In Microsoft OneNote 2013 for Android, is it possible to move a page from one folder or section to another?

Unfortunately the functionality to move pages between different sections doesn't appear to be available. I would love it if you could move pages between sections, and even move sections between different notebooks.

As a workaround, the functionality IS available on the web version of OneNote. If you have the OneNote notebook stored in your OneDrive (which I can't see ANY reason why you wouldn't) then log into www.onenote.com and move the pages between sections using the browser.

Then, sync your notebook with your Android device again.


I don't know if there is a way to save them directly on the device, but I do know of a tool called SMS Backup + that I have been using almost since my fist android phone in 2008, and before I used SMS Backup +, I used SMS Backup.

This application will backup your SMS messages and Call Log to your gmail. It puts them in to SMS/CallLog labels so they don't clutter your inbox, but it is a very handy thing to have all your messages backed up. Especially when your wife says "I told you to get 3 loafs of bread", you can pull up and say, "Nope, see you said 30 loafs"...

SMS Backup + can not only backup your SMS/Call Log, but it can also restore them. The developer says MMS is also "coming soon". (but he has said that for a while not, not that I am in any rush for that feature). And, did I mention, the app is free.

Even if I was able to save them to my phone, I would have deleted them 100x over by now with all the times I have done factory resets, new sdcards, etc. Gmail also has way more storage available then my SIM, device, or sdcard. It is also more reliable. I have never lost data stored in my gmail, but I have had 4 sdcards fail on me.


Go into your Settings/Language & Input.  Under "Keyboard & Input Methods" hit the settings icon next to your keyboard.  Scroll down to "Text Correction" hit "Auto Correction" and select "Off". That should do the trick.


First of all, since you've modified the system, the OTA update could very well fail partway through -- most of those are distributed as patches against the existing binaries.

The easy way to update is to find a pre-rooted stock ROM, like this one.  You may  need to update your radio first though, information and download links are available here.  I think the one you have was the official Froyo radio -- you'll need the Gingerbread radio for newer ROMs to work properly.  2.15.10.07.07 is the official Gingerbread radio.

However, if you want to go the hard way, keeping root (or at least the ability to re-root easily) is easy provided your Incredible is NAND unlocked (aka S-OFF).  Recent versions of Unrevoked do this automatically, but depending on where you downloaded from and when could affect that.

To check if you're S-OFF, reboot into the bootloader (aka HBOOT).  To do that, power off the phone, then hold down the volume down button and power it up.  Keep the Vol Dn button held until you get a screen like the following:

You can also see the notification that it has S-OFF at the top of the screen.  That's what you want to see.  If that's missing (or says S-ON), then you don't have S-OFF.  If you're not, get the latest Unrevoked Forever.

Once that's done, you can flash whatever you want and still be able to reroot easily by simply flashing your recovery of choice (often ClockworkMod) from HBOOT and then reflashing a root/superuser package from recovery.


I can't open or close any tabs on my Android tablet in Chrome

I had this issue too on my Galaxy Tab A.
I found a workaround. It's not the fix just a workaround. Please enable rotation of display btw. landscape and portrait. Each time you encounter this issue so you cannot close any Chrome Tabs any longer just rotate your display. That's it!
Regards and stay healthy!

Yes and no. As far as I'm aware, a typical Android install will not contain unzip. You can, however, install busybox for Android, which provides the unzip utility. Then a simple:

adb shell unzip /sdcard/archive.zip

Would do the trick. If you're rooted you can use a busybox installer from the Market like Stericson's. If you're not rooted then you should be able to manually push a busybox binary (one here on Github, for example; click "raw" to download it) to somewhere like /data/local and then invoke it. It should be something like:

adb push /path/to/busybox-android /data/local/busybox
adb shell chmod 0755 /data/local/busybox #Make it executable
adb shell /data/local/busybox unzip /sdcard/archive.zip

Alternatively, many file managers will unzip files for you. I personally use File Expert but there are a lot of others. Usually you just need to long press on the archive and it will present an "extract" option or similar.


Mysterious documents in internal storage -android

Nothing mysterious their it looks like app data and its common in all android mobiles


Why are apps slowing down my phone just by being installed?

Phones use Solid State Drives (SSDs) for storage instead of traditional Hard Drives (HDDs). This is because carrying and jostling HDDs can cause hardware problems.

Solid State Drives, however, get slow as you fill them up. So when you start to fill up your phone, its storage gets slower. This means that it takes longer to read the code from storage into RAM to execute.

It should also be noted that the description on Autorun Manager says that some apps will just attempt to restart themselves after it kills them. This constant restarting-killing behavior could possibly be even harder on system resources that just letting the background app run, so be careful which apps you kill.

Some background tasks help apps start-up faster too. I can start up a heck of a lot faster if I've already updated my app while you weren't using it. Instead of waiting for my app to get all of the data it needs when you open it, it grabs it in the background and can just display it when you open the app.

Also, if your device has very little RAM, then it can only hold a couple of apps in there at a time. If the apps you're opening have been erased from RAM, you phone has to erase another app from RAM and use that space for the new app.

Basically, there are a ton of reasons why your phone could be acting slow, and it's probably a combination of them that's causing your phone to act so poorly.


How to make hangouts forget your accounts password

One way to do this would be to:

Go to Settings
choose Applications (or applications manager)
swipe left/right to see all (installed) applications
click on Hangouts then Clear all data.

Note: This erases all data Hangouts had stored on your phone (just in case, you might want to do backup first).


Is there any old style keyboard (numpad style) available for Android?

Well...Look for a keyboard that has a T9 layout.

As an example, I use Smart Keyboard Pro (which is a paid app, but a trial is available) and you can choose from the full, T9 and compact modes for portrait as well as landscape orientation. There are tons of other customizable options and considering that a keyboard that one is comfortable with, is what allows one to at their productive best, I opted to buy the full version.

How to enable mobile network in Android Tablet

According to the specs you linked, this tablet doesn't support 3G mobile networks, only GSM. To enable the mobile network features, you need to buy a 3G USB dongle and connect it to the tablet.


Toggling USB mass storage on (or off) via adb commands

Alas, the UsbStorageActivity doesn't use an intent to enable and disable USB mass storage, so there's no way to achieve this using am. It instead calls the functions StorageManager.enableUsbMassStorage and `StorageManager.disableUsbMassStorage to do its work. As these functions are hidden in the framework, it's not possible to write an app to do this, either. As far as I know, there's no existing command to do this.

It might be possible to write an app that offers a command-line interface and uses the bound system service MountService to call its setUsbMassStorageEnabled function, but that would be way off-topic for this site.


Task Manager and profiler for Android Wear apps

I've been unable to find any profiling apps designed for Android smartwatches. However, its been reported that Trepn Profiler can be used with Android Wear smartwatches. Here is a screenshot of Trepn running on the LG Watch R:

Based on the data I've seen, this smartwatch reports accurate power consumption:

With a dim display, 252 mW of power is consumed.
With a bright display, 671 mW is used.

It looks like the above screenshot was created using Trepn's 'Network Activity' preset.

Obviously Trepn is not ideal for this purpose, since it was never designed to run on a smartwatch. You won't be able to access important features like its Advanced mode or Settings.

Although I haven't tested them yet, I would expect all of Trepn's overlay presets to work. Note: To make sure you have an overlay preset, touch the icon to the right that looks like an overlay, not a list. In most cases it's the bottom icon.

Disclosure: I work on the team that created Trepn and App Tune-up Kit.


This XDA thread provides a method for rooting without unlocking, though I don't know if it will still work for 2.3.6.  Worth a shot.  If I doesn't I think you'd need to downgrade your firmware to avoid unlocking, which would wipe your data anyways.

As for backing up without root, see How can data on an unrooted phone be backed up?


You can save data usage recordings using an ADB command like the following:

adb shell dumpsys netstats detail full > data_usage.txt

If you are interested in the data usage of a specific application, you can find its identifier (which is used in the above recordings) using a command like the following:

adb shell dumpsys package com.example.application | grep userId

How do I stop voice typing from muting/pausing other playing media?

As you know the voice typing feature works by listening to microphone of the device in use and any device where you use voice typing would behave same as if the device keeps playing the audio and also try to listen to microphone at the very same time, it may end up listening to the audio that the device itself is playing and would cause conflict between the user's voice or external voice and audio played by device
Generally this is the standard way voice typing work on any device not only android, i just tried this thing on windows Cortana and it reduced the speaker voice to very low level while the conversation was going on
In short i guess that wouldn't be possible without going too deep inside the system and modifying system files


The built-in Google Voice Commands can't (at this time) launch apps.

However, a quick search on the Market revealed a few possible alternatives. Here are two:

message saying "disable harmful apps Galaxy apps can damage your device"

Galaxy Apps is Samsung's Appstore for its own software, which are usually variants of apps produced and distributed by Google through Google Play Store. There is generally a complement app for every Google App. Galaxy Apps, the Appstore frontend, is not unsafe, but it can be a propaganda spread by other appstores and virus checkers to dissuade you from downloading and using Samsung APKs there. The official opinion is that ANY APKs distributed through any appstore than Google's Play Store can be unsafe, and as a consequence, to install Galaxy Apps distributed APKs demands the permission "Install unknown/outside apps". Something is warning you about this setting; accept the warning under this understanding or remove whatever checking is in place.

EDIT: as of my Samsung Galaxy S8, or possibly earlier, Galaxy Apps CANNOT be disabled, so while whatever is possibly reporting a false safety warning, it may also be hinting that the app may be unsafe but can be corrected with a more current update?


Some apps not supported on Samsung Galaxy Player

Developers can choose to target specific devices or not.  Presumably these apps are either limited to devices that are known to work, or have blacklisted the Galaxy Player due to incompatibility.

Another option is that some apps might be available only while connected to a cell network or a particular cell network.  There are some AT&T apps that are only available to those on AT&T, for example, and I imagine this might be more broadly the case.

Here are some workarounds:

Get the app via another (legitimate) means, possibly the developer's site or another app market.
Use an app like MarketEnabler (requires root) to fake a different network.
Edit your /system/build.prop file to report your device as a different device.  Only edit the device name and versions and so on, not other settings, or your device may stop working!  You should be able to Google the various fields for other devices and see what to use if you want to mimic one.

Note that doing 2 or 3 in order to circumvent distribution controls may not be legal in your region.  The onus is on you to ensure you are acting legally.  I am not a lawyer and this is not legal advice. Etc.


UPDATE: According to a comment below, the OpenMic+ app has been taken down by the author.

According to Google Help Forums, this feature seems  not to have been implemented yet:

  At this moment, changing the hotword is not an available feature.
  However, we appreciate your feedback, and your feature request has
  been noted.

Fortunately there is a workaround:

There is an application, Open Mic+ for Google Now, with lots of customisation and enables the user to change the hot phrase.

  With Open Mic+ you aren’t limited to “Okay Google”. Live out your
  sci-fi fantasies, support your favourite team, and just feel awesome
  with complete control over your phone.

Instructions:

Download and install the latest version of Google Search App on your device if you haven’t already.
Download and install Open Mic+ For Google Now App.
After installation ,open the app Open Mic+ For Google Now.
As soon as you open up the app you will see a warning indicating you to turn off Google Now Hot word Detection, here click on Settings >>Voice >> OK Google Detection >> Turn it Off.
Now head back to Open Mic+ For Google Now App and tap on Say area with a pencil icon.
Here type any command with which you want your Google Now respond like “Hey Device” and then hit Set.
Once set click on the Play button.
That’s it you now have successfully customized and changed Google Now wake up command from OK Google to something else in this case to Hey Device.

Hope this helps

Note 4 contact quit syncing with Outlook

Try this tool for testing whether the problem is in your Note 4 or in the exchange: http://www.akruto.com/best-ways-to-sync-android-with-microsoft-outlook/

This should work at least for identifying the source of the problem. If you would sync your smartphone with Outlook using this software then it means that the problem is somewhere inside of exchange settings. If this software would act just like your current connection, try to check for special characters and the like in your address book.


Note 8 dies when battery is drained completely

Since it's a Note 8, it MAY still be covered by a warranty. If so, take the phone to the store you bought it, they should look it up for you, and if it needs any repair they will take care of it, since as far as I can tell it's not your fault.


Google Account activation: What should I consider concerning privacy?

On activation of a Google account on your device, you will be asked whether you want to backup your data to the Google cloud. While this must be explicitly supported by the apps to take effect for their data (which only a few do), and thus will never be a complete data backup, many of your most private data will be affected here – amongst others your WiFi APs including their (plain text!) passwords, which even might lead to other issues beside privacy. But even if you answer this with "No", your contacts, calendars, and more will be automatically sync'd with the Google cloud without you being explicitly asked for.

So here are some things you might want to consider. The list is definitly not complete, I certainly have missed some points (and might add some lateron).

"Do you want to backup …" (see above): This includes data of some apps which support it, a list of apps installed on the device – but also sensitive data such as configured WiFi APs with their passwords in plain-text (open issue #57560)
In the sync settings of your Google account, de-select what you don't want to sync. Do this before entering any of your private data (contacts, calendars, etc.), and remember you will have to re-do this after a factory-reset. Side-effect: the less you sync, the less this can eat your data-plan.
Consider switching the default storage in your contacts/calendar/... app from "Google Account" to "Device"1
Android 4.4+: Install an alternative SMS app and make it the default one (in Settings→WiFi you can chose which app to be used for SMS) to avoid your messages being mixed into Hangouts. To be on the safe side, you can also disable SMS support in Hangouts.
Android 4.4+: Install an alternative Gallery app2 to avoid your images being mixed with Google+ (looks like the separate gallery app will be gone soon as well). Side-effect: again savings on your data-plan for not automatically syncing all your photos (alternatively, photo sync/instant upload can also be turned off in G+ settings AFAIK).
Avoid services like Google+ which are quite intrusive to privacy. If that's not an option for you, check their settings thoroughly, and opt-out from intrusives whereever possible.
Disable Google Maps and replace it by a good alternative. Apps like the open-source OsmAnd, OruxMaps, or Locus Map not only offer you much better offline capabilities, but also save your device's juice by not constantly running in the background even without being explicitly started by you.
If you followed all above suggestions, you now might as well think about disabling Google Now – it no longer can tell you it's "10 minutes to your parents", or "you need to start to work earlier because of higher traffic", as it doesn't know where (or who) your parents are, and where your work place is (or what the traffic conditions are). And cannot give you advices like "buying this because your friends like it".
Just discovered: Google Settings › Smart Lock for Passwords. Enabled by default, it saves passwords of your apps and websites to Google's cloud (your account). Not sure if it honors the initial "Do you want to backup …" setting.

There are several more things you can do for your privacy, not being restricted to Google's services. If rooting is an option for you, things like Xprivacy are definitly worth a look. A good starting point are our privacy tag-wiki and other questions tagged "privacy".

PS: Turning WiFi off when you don't need it (with 4.3+, remember there's also the "keep scanning for networks even if WiFi is switched off" setting in Settings→WiFi→Advanced to be considered) could even protect you against being tracked by advertising trashcans...

Dialer app becoming too slow and less responsive

This is likely a combination of two things: a) stuff that the dialer has to load on startup and b) possibly shortage of memory (RAM) created by loading those things. The biggest gains are to be had by resolving (a) however, this will also have the side effect of resolving (b)

You might like to try clearing the following:

Call log - this is loaded each time the dialer is loaded.
SMS messages - Some users have reported that a large number of SMS messages can cause the dialer to slow down, though I'm sceptical that this makes a difference.
Contacts - finally, the number of contacts does have a bearing. Not only the ones you can see ("My Contacts"), but anyone you've ever emailed (i.e. Other contacts in GMail contacts).

The last point can be quite important. I have about 130 'real' contacts but nearly 1000 people I've emailed at some point while using GMail. There were all being synced to my phone, just not always shown.

It is important to make the distinction between RAM and persistent storage. For example, clearing out your trash, deleting emails, uninstalling unused apps, or moving them to SD storage is unlikely to help, because these are using up persistent storage, not transient RAM.

Having lots of persistence storage free means just that apps can't use it to run any faster. RAM, however, can make them fly.

You might also like to take a look at Superdial and Dialer One, two dialers that I've found most agreeable. They also have T9 contact lookup, which can be a dream to use.

How to encrypt full device on Android Nougat?

Head to Settings > Security > Screen Lock and tap your current screen lock. If “require PIN to start device” is an option, you’re running full-disk encryption.

If you’d like to convert to file-based encryption, you can do so by enabling Developer Options, then heading into Developer Options and tapping the “Covert to file encryption” option. Keep in mind that this will erase all of your data, effectively factory resetting the device!

Here is the full tutorial from howToGeek.


Can we make a Vpn server run on Android?

Yes we can run VPN server on Android, but not without root. Stock Android doesn't support VPN servers, even many protocols aren't supported as client too, so you have to install third party apps. There are apps like Servers Ultimate which offer VPN server, but I haven't tested. CLI keeps life simple:

Build openvpn static binary and copy to /system/bin.
Create a basic server configuration file:

### /etc/openvpn/server.conf

# basic configuration
port 69
proto udp
dev tun
mode server
tls-server
keepalive 10 120

# dynamic IP pool
server 10.8.0.0 255.255.255.0

# send RESTART command to clients if tunnel is restarted (UDP)
explicit-exit-notify 1

# configure like a "traditional" broadcast-based network
topology subnet
push "topology subnet"

# send all traffic from client to VPN
push "redirect-gateway def1 bypass-dhcp"

# DNS nameservers
push "dhcp-option DNS 1.1.1.1"
push "dhcp-option DNS 1.0.0.1"

# certificates and keys to use
ca ca.crt
cert server.crt
key server.key
dh dh2048.pem
tls-crypt tc.key

# cipher algorithm to use for encryption
cipher AES-256-CBC

# log files
log /data/media/0/openvpn.log
status /data/media/0/openvpn-status.log
verb 3

# do not recreate TUN interface on reset (SIGUSR1)
persist-tun

# do not reread key files on reset (SIGUSR1)
persist-key

Create server keys and certificates. tc.key can be created by executing openvpn --genkey --secret tc.key.
ca.crt, server.key, server.crt and dh2048.pem are built using EasyRSA. It can be done easily on a Linux/Windows PC, on Android it rquires some extra effort:

~$ easyrsa init-pki
~$ easyrsa build-ca
~$ easyrsa build-server-full server nopass
~$ easyrsa gen-dh

Copy configuration file, certificates and keys to /etc/openvpn/ and set permissions:

~# chmod 0600 /etc/openvpn/{ca.crt,dh2048.pem,server.crt,server.key,tc.key}
~# chmod 0644 /etc/openvpn/server.conf
~# chmod 0755 /system/bin/openvpn
~# chown -R 0.0 /etc/openvpn /system/bin/openvpn

In the same way build client key and certificate using EasyRSA:

~$ easyrsa --days=30 build-client-full client nopass

Copy the contents of ca.cert, client.key, client.crt and tc.key to client configuration file. Also add public IP address of Android device if want to connect from internet or local (WiFi/hotspot) IP address:

### client.ovpn

client
dev tun
auth-nocache
verb 3

remote-cert-tls server
cipher AES-256-CBC

pull
resolv-retry infinite

remote <IP_ADDRESS> 69 udp
nobind
connect-retry 5 5
connect-timeout 10

# only for Windows
#block-outside-dns

<ca> INSERT_HERE </ca>
<cert> INSERT_HERE </cert>
<key> INSERT_HERE </key>
<tls-crypt> INSERT_HERE </tls-crypt>

Android ignores main table at all, create custom rule and insert routes:

~# ip rule add table 5000 priority 5000
~# ip route add 10.8.0.0/24 dev tun0 table 5000
~# ip route add 192.168.43.0/24 dev wlan0 table 5000
~# ip route add default dev rmnet_data1 table 5000

Where rmnet_data1 is the interface connecting to Mobile Data and wlan0 is WiFi or hotspot. Adjust interface names and network addresses according to your device.

Setup forwarding and source NAT:

~# echo -n 1 >/proc/sys/net/ipv4/ip_forward
~# iptables -I FORWARD -i tun+ -j ACCEPT
~# iptables -I FORWARD -o tun+ -j ACCEPT
~# iptables -t nat -I POSTROUTING -o rmnet_data1 -j MASQUERADE

Run server, but first make a minor adjustment due to difference in Android vs. Linux:

~# mkdir /dev/net
~# ln -s /dev/tun /dev/net/tun

~# openvpn --cd /etc/openvpn/ --config server.conf

Import the client.ovpn in any OpenVPN client app (on Android / Windows / Linux) and connect.

You can do advanced configuration on server, run it as an Android init service, or what ever you want.

Though I've never seen this kind of notification sticking (or even appearing): It's obviously informing you that your SD card was mounted. Note that almost all recent Android devices come with an internal-sd card – so even if you have no external card, there's still one that should be mounted.

The other part of your question is a general one on notifications. First, there are two kind of notifications: the best known are those just giving you a one-time information, and you can simply "swipe them out". The other kind are so-called "ongoing notifications", and they "stick" (i.e. they cannot be "swiped out"). The only way to get rid of them is "silencing" the app giving them. Long-pressing a notification gives you a menu to do exactly that: telling the system you don't want this app giving you notifications.

Host usb application not recognizing my usb devices?

This result indicates that your device claims to support USB host mode, but that it doesn't actually work.

There are 6 reasons I can think of that would cause you would get this result:

A. You did the test wrong and didn't plug things in at the specified time.  Try it again and follow the instructions exactly.

B. Your USB host cable is defective or is not actually a usb host cable.  Try it again with another cable or the correct cable.

C. You used an improper device (e.g. a device that tries to draw more current than the tablet can supply, like an external hard drive, rather than a flash drive) and thus the test failed as it couldn't detect the device, because the device was unable to power up successfully.  Try it again with a different device.

D. Your device claims it supports USB host mode, but due to a software bug, it doesn't work.  An update or custom ROM may fix this.

E. Your device claims it supports USB host mode, but the hardware doesn't actually support it.  You're SOL unless you can return this device to exchange it for a Real Tablet.

F. Your device is a weird piece of work regarding USB.  Some android devices (such as the HTC Incredible S) technically implement USB host mode, but they won't provide power to the attached device.  In this case, you need to provide the juice yourself, via a self-powered hub or similar.

What's the purpose of "Emergency Call" button on SIM unlock screen?

It is required for phones (at least in Europe and US) to allow emergency calls without requiring the user to unlock the phone or the SIM card. You can always make an emergency call when you're in a cell coverage area and the phone has power. It's a safety feature, which guarantees you can use any phone in an emergency to get assistance, regardless of the state the phone is in.

Take this scenario: you're in a car crash and your own phone breaks. An unconscious friend's cell phone is working, but it has a pattern/PIN/password lock on it, or it lost power but boots to the SIM PIN screen. The feature guarantees that you can make the call without knowledge of the correct pattern/PIN/password.

The numbers you can call with this feature are restricted to the most common or regional emergency numbers, and are translated by the carrier to the local emergency numbers if you're roaming.

The exception to this are WiFi-only tablets, which can't make calls at all.

Edit:
If the device's SIM is locked, it detects the networks available and identifies it's own network, but doesn't register the device to the network. In the case of emergency calls, the phone doesn't need to be registered to the network, all calls to emergency numbers are allowed, regardless of the state of the SIM or carrier subscription. Even with no SIM at all, the networks are detected and the carrier with the strongest signal is used.


A widget to show tasks that are two days closer to due date

Pure Calendar Widget (not free) has an option for how many days ahead to show calendar/task entries for.  There is an option for 2 days that would suit your needs perfectly.  Note that you will need a supported app to sync the tasks from Google (GTasks, Astrid, etc.)  See the list of supported task apps here.


is it required to do unlocking of bootloader before installing and upgraded rom for sm-g550t galaxy on5 and then reroot

As Samsung hasn't updated your device to android 7.0 so in order to upgrade your android version you have to unlock bootloader then flash a custom recovery.

Then you can flash any 7.0 custom rom.


listen to radio on xperia ray with wireless headset

Most of phones (including Xperia series) does not have an internal FM radio antenna, so they need a wired headset to be inserted, in order to use its wire as antenna.

You cannot use FM radio until you plug a wired headset to the phone.


Fast Charging can be achieved in two ways

Hardware based Charging

Qualcomm-  Qualcomm Quick Charge 2.0 and Qualcomm quick Charge 3.0. Also see Fast Charging by Qualcomm 3.0- impact on battery?. This is the most popular, adopted by OEMs under various brand names
Type C USB Charging- USB Type C Charging explained. Also see Android phone “charging slowly”: How to make it faster
By OPPO- VOOC (Voltage Open Loop Multi-step Constant-Current Charging) and Super VOOC

Kernels (including kernel tweaks) capable of increasing charge rate whether it is USB or wall outlet charging

First part of your question How does fast charging work? Does it actually charge your device faster

This has been covered at length here (linking it rather than copy-paste) Will plugging the Samsung fast charger into a outlet rated 10W/2.1AMP slow down the charge rate?.

To summarise, normal charging is done at 0.5 to 0.8 C (C is charge rate) and fast charging done at 1 to 3 C. Please note that the exact or indicative charging rate is not revealed in any OEM documentation despite extensive search and it is unlikely that OEMs will reveal such  details, deeming it "proprietary"

Coming to the second part of your question Is there a downside to it (Fast Charging)?

Yes, in two ways:

A common feature while using fast chargers is raise in temperature of battery (since more current is being pumped in and power (read heat) is proportional to square of current) and this is inimical to good health of battery, which is extensively  covered here.

Short Term (Battery capacity after charging) Battery is not really fully charged as it does not undergo charging spending enough time in all stages, compared to conventional charging. In simple words battery may deliver typically 85% of performance compared to regular charging. Details on this are available here
Long Term (Battery life span) Battery life is specified in Cycles or discharge cycles. OEMs/ Battery resellers may specify this number, for example, it is 550 Cycles for Samsung Note 2

Quoting from BU-501: Basics About Discharging

  What Constitutes a Discharge Cycle?

  A discharge/charge cycle is commonly understood as the full discharge of a charged battery with subsequent recharge, but this is not always the case. Batteries are seldom fully discharged and manufacturers often use the 80 percent depth-of-discharge (DoD) formula to rate a battery, meaning that only 80 percent of the available energy is delivered and 20 percent remains in reserve. Cycling a battery at less than full discharge increases service life and manufacturers argue that this is closer to a field representation because batteries are commonly recharged with some spare capacity left.

  There is no standard definition as to what constitutes a discharge cycle.

This does not mean that every time you charge you are consuming a cycle

  For example, if you discharge a battery to 50 percent one day, charge it back to 100 percent, then discharge it 50 percent again the next day, that is counted as one "cycle" of the battery. So shallow discharges, in all these regards, are ideal for a Li-ion battery.

Now that battery life in cycles has been explained, let us see how fast charging adversely affects long term battery life

Figure 2 from BU-401a: Fast and Ultra-fast Chargers graphically shows deterioration in long term battery life. Note deterioration in charge holding capacity and life of battery are both affected adversely

Figure 2: Cycle performance of Li-ion with 1C, 2C and 3C charge and discharge
Charging and discharging Li-ion above 1C reduces service life. Use a slower charge and discharge if possible. This rule applies to most batteries.

Bottom Line: Use fast charging when you "have to" due to time constraints else if possible stick to normal charging if you care for your battery( if you have read this lengthy answer, it's because you care:). But a relevant question is what can be done if your cell is equipped only with a fast charger? Answer would be to use a battery pack for normal use and fast charging when you really need it. This way, you could end up spending more but wouldn't need to bother about battery health

Perhaps realizing that ill effects of fast charging would be negative, Samsung has come up with user selectable enable/disable fast charge option

See FoneArena Labs : Best Fast Charging Standard in the market for performance comparison of different charging techniques


How can I get the stock mail application in Android to sync all my Exchange/Outlook contact folders?

Touchdown is your only option to fix this. An admin at my company got his Motorola Droid 2 and had the same problem. We tried everything we could find online in an attempt to sync all his contacts. Eventually we came across touchdown, paid the 19.99 and it worked fine. With the exception of notes it cleared up all the short comings of the stock Android Exchange sync.

Side Note: I don't personally use Touchdown nor am I affiliated with them in any way.


Android Market auto restore apps not working

I recently did a factory reset and I can see all of the apps that I'd previously had installed, not just the ones I've only just gotten around to.


Get Windows PC Notifications/Updates on Android Mobile

The implementation of what you are asking is too application-specific to work well for most computer applications, thus the usual (and possibly only) solution you will find is use some screensharing app. All applications handle such notifications differently, so it would be too hard to make it work for all applications correctly.


Unable to install system images for the Android SDK: "Failed to create directory"

How can I easily tag a photo I am previewing?

F-Stop Media Gallery does exactly that. You can preview photos and it has an on-screen 5 star rating and "favorite" button.
Unfortunately, the tags don't "stay" with the photo if you upload to Google+ or Facebook.


delete all email from Samsung galaxy s3 at one time?

Go to Settings => Storage => Used Space => Applications

Find your email app in the list and select it. For example mine is Gmail.

Click on "Clear data". You will get a warning saying you will have to set up your account again. It is your choice if this is what you want to do.

Once you have done this, go back into your email app as you normally would to check your emails and enter your account details. In the Settings of your email app you should set things up not to keep so much email. So for example in Gmail you can reduce "Days of mail to sync" from the default 30 to for example 5.


stuck trying to fix bad Android 6.0 update

The solution was simply booting in fastboot mode (I already was there). Apparently, booting in fastboot → plugging in the USB cable → waiting a couple of minutes for the device to be detected by ADB (adb devices) works best (otherwise it won't list the device). I was then able to install Android 6.0 successfully via fastboot commands (USB debugging and OEM unlocking were previously enabled and the bootloader unlocked).

fastboot flash bootloader bootloader-flounder-3.48.0.0135.img
fastboot reboot-bootloader
fastboot flash recovery recovery.img
fastboot flash boot boot.img
mfastboot flash system system.img
fastboot flash vendor vendor.img
fastboot flash cache cache.img
fastboot reboot

mfastboot was used instead of fastboot to flash the system.img file because the latter gave an "could not allocate -1995847632" error message (it can't handle big image files).

I will re-lock the bootloader later.


Unsure if 'adb push' has completed correctly in recovery mode

After that line (X bytes in Y seconds) appears, transfer has been completed.


Tune-in to next radio station on FM radio without unlocking the phone

Have you tired to double press the button in your headset? The stock radio player app should do it. And in case if does not there are plenty of apps (Headset Control Center to name one) in market that can recognise the double press and do a task for you, which could be change the radio station.

Update:
After realizing the absence of headset button through the OP's comment, I suggest to use Tasker and Intent Radio app.  The concept is that the Tasker can be used to identify a trigger. This could be head set plug in, head set removed, power button pressed, volume buttom pressed, movement gesture - few listed out of many options.  This trigger will raise an intent to the Intent Radio which can change the radio station.


Try running "sudo adb devices". Or, fix your udev rules so that the USB device is writable by your user (see the link in caffinatedmonkey's comment)


I cannot provide a definitive answer, but some folks have had over 20,000 messages, based on this Reddit discussion. So if there are any limits, it may have been set by the OEM (or their custom app). Using 3rd-party SMS apps might provide a workaround to the limit.

I would bet that if are hundreds of thousands of messages, there could be a significant performance issue, although that may depend on how the app processes the records. Go SMS Pro, for example, does not load the messages all at once. But if it reaches the point where it has loaded already a lot of messages, the app slows down.

UPDATE #1: To paraphrase Izzy, the storage limit will also trigger the "insufficient memory" error, usually when there's less than ~25 MB free space on internal storage. This would also prevent the SMS from being stored (plus the possibility to send some on your own).


Does Android support the single-user mode runlevel?

Single user boot is a feature of the init daemon (initd, like sysVinit) and not the Linux kernel. Since Android only shares the kernel with Linux and not the init process, a genuine single user boot can not be achieved.

Android has something that is called "Recovery Mode", but it's not exactly the same as a single user boot on an Unix system. The approach of recovery mode on Android is different because instead of trying to repair the bricked/broken system, on simply can re-flash the ROM or perform a factory reset, which will hopefully restore the systems functionality.

About the init used: Android uses just a script called init.rc, which gets started by the kernel and is used to start further services. You can view the current source of init.rc here. It supports no runlevels.

What is rootfs? Can I make persistent changes to my device's root filesystem?

What is rootfs?

It's an initramfs. Basically, it's a prepopulated RAM drive. It's prepopulated with some content at boot time, usually from a cpio archive which has been compiled into the kernel.

Can I write to it?

One way to make changes to your rootfs is to unpack the cpio archive, make your changes, and repack the archive.  Your device will almost surely have to be rooted before you can do this.  As well, you'll need the necessary tools.
Alternatively, you can make changes to the rootfs copy which is loaded into RAM; but, if you do so, there are four gotchas.

You must root your device first.
Then, you must remount the filesystem as read-write.
Don't write too much to the rootfs; if you do, you'll take up too much RAM and your device will slow down.
The biggest gotcha is that the files you create will disappear when you shut down or reboot. Please keep on reading.

Will my changes persist even after I shut the device down?

No. If you create or modify files in rootfs, your changes will be undone when you shut down or reboot.

What should I do instead of writing to the root filesystem?

Store your files somewhere under /storage or /data or /system instead. You can choose any of the three. Somewhere under /storage is probably best, since that's the most common choice.

Why doesn't my device act like a normal Linux device and mount a normal disk-backed filesystem to /?

I don't know.

I suspect that the answer is as follows:  Android isn't a full Linux distribution.  It doesn't include a full glibc, it's probably not fully LSB-compliant, and it doesn't feel obligated to provide the niceties that most Linux distributions provide (e.g. a disk-backed root filesystem).

Elsewhere, Gilles writes:

  Most desktop Linux systems have a small initramfs which contains just enough programs and configuration files to mount the real root filesystem, which is then mounted on /, replacing the initramfs. Android, like some embedded Linux systems, keeps the initramfs mounted forever. Android's initramfs contains only /init, adbd and a few configuration files.

Can the Droid Eris be charged on a PowerPlate Wireless Induction Charging Base?

eldarerathis is right.  The PowerPlate is a two part system.  1. The Base and 2. The Receiver.  The receiver clips onto the phone and is specific to the phone.  It looks like the powerplate system replaces the battery cover on the blackberry and is a snap-on cover for the iphone.

Duracell makes an inductive charger that is compatible with the Eris.  PowerMat doesn't have an Eris receiver but they have some universals.  Or you could hack your own solution.


Turn off notifications for old unread emails and only keep for new emails in gmail

As confirmed , the solution that worked is posted below

You can try automation.  I prefer Macrodroid, being easy to learn and free (upto 5 macros)

Create a macro

Trigger: Notification → Notification received  → Select Application  → Gmail  → Text content contains  → Enter here the text you see on the unread notifications

Actions:

Clear Notifications  → Clear all
Optional if you don't want notification sound Volume Change  → Set notification on slider scale to zero

Constraints : Leave blank


Generate a browser bookmark from file manager

As suggested by t0mm13b in his comment on your question, a shortcut on the desktop is the easiest way. This requires you to first open the page with your browser, and create a bookmark for it (you will see later why this step is required).

As you stated not to be able to add the shortcut in the usual way, here comes an alternative approach:

Some tablets come with a launcher that only offers wallpaper settings on long press (I have some of those as well). In this case, oben the app drawer (where you can find all your apps), and switch to the "widgets" tab (usually by swiping the page from right to left). You will see the word "Widgets" highlighted on top. Now look out for the "bookmarks" widget. You may be offered multiple of them, from "1x1" to "4x4" (the numbers here specify the size the widget will consume on your screen). You can play with them to find the one suiting you best. Long-PRess it, and the drawer behind it will "fade out" -- instead your homescreen(s) will display. Drop the widget where you want to have it.

Now it will ask you for which bookmark you want to use for the widget. Chose the bookmark you created in your browser at the beginning. Now the widget should be created on your homescreen.


My HTC Android Touch is creating problems some times

It might be a digitizer problem, you should take it to a warranty. Usually problems like that can be cause of a digitizer issue.


Which system process do I block from the internet to prevent ads from showing up?

Such ads are not fetched from the internet, they are built into the app. Usually the ads would feature some other app from the same developer.


By installing a different version of Cyanogenmod. Android is not like Windows, where you have to install each driver separately: all the drivers come integrated in the ROM. Sometimes, with third-party ROMs like Cyanogenmod, they don't quite manage to integrate the drivers properly (because only the manufacturer has all the required information), so you get defects like this one.

If you found the problem in a stable release, release candidate, or beta of Cyanogenmod, you should report it to the maintainers for your phone so they can fix it. If you've been using a nightly snapshot, don't bother, as they are expected to have serious errors and aren't suitable for everyday use.

Upgrade to a newer release if there is one, or perhaps to an older release.


Why don't see notifications on 5.0.2 Android update for Sony Z3 Compact

I think the problem is that you are using the PIN lock screen. Try changing to something else and hopefully it will work.

I also faced this problem and it disappeared when I changed the lock screen type.


There is different method from Android 9 and later.
For Android 9 and 10 devices, ensure to disable dm_verity by flashing an empty vbmeta before flashing magisk patched boot. Some devices most especially those using Unisoc chipset require that you generate your custom signed vbmeta.
Sorry, I don't know more but only this difference about Android 9 or newer.


How to share my mp3 collection with my family's android devices?

The first thing that comes to mind is network-based sharing. A common solution is Plex.

Ideally you would install Plex Server on a device that is on 24/7, like a NAS/router/home server. Then install Plex Clients on each device and connect with the Server.  The added advantage is Plex allows connections from over the Internet if you configure it to do so. So you can access the songs from work/school/car etc.

If you don't want to set up the full-time Plex Server, but just share from your phone over LAN, then you can also use the Plex client on your phone to serve the files. But using the client to serve means it is UPnP, so not easily accessible over the Internet. (You can't install Plex Server on Android OS).

TLDR; install Plex clients on all your devices. This solution is not free. If you just want LAN sharing, there are free DLNA apps like bubbleupnp. I personally use a Servers Ultimate server with Ginkgo DLNA clients. Ginkgo is very small if your family just want to consume your content.


How can I get Google Navigation (navigation in Maps) on Android to navigate walking directions?

Take a photo in PNG (or other lossless) format

If you really want to take lossless photographs, you should look for a camera app with RAW support. Typically, you would be working with a .dng file, instead of a .png file. RAW photos are lossless and uncompressed, which is what you're looking for, and (as the name suggests) captures the raw data from the camera's sensor.

The Lollipop Camera2 API includes a feature to capture RAW images, and there are at least a few popular apps that take advantage of this.

OpenCamera (Free, Open Source)
Manual Camera (try the compatibility checker app before buying)
Camera FV-5


GPS Battery Drain -- LocationManagerService

Short answer:
Simply reboot the device. I've had that on multiple devices already, a reboot always cured this.
Explanation:
The real culprit is not the LocationManagerService itself, but the way how is dealt with it. In my answer to the question How to deal with (orphaned) WakeLocks? you find a section called What if it is the Android System itself?, which explains this to a degree (and offers a link to further information):
An app might have requested location updates with a frequency of 0 seconds, thus keeping the device busy. Instead of requesting a "partial wakelock" (with an appropriate auto-timeout), it might have requested a permanent one (which it needs to release explicitly). If now this app crashed, the wakelock gets orphaned, the request for location updates remains, and nothing (but a reboot) can solve this.
This is just a raw description and probably not 100% technically perfect -- but I tried to put it into "laymen's words" to make it easier to understand. If somebody wants to put the details into "technically perfect terms", feel free to do so :)


What precisely is CloudAgent process? Its files eats space like crazy

It's Samsung software, built into the system in certain Samsung phones. Like the Dropbox app, it's a service to automatically upload photos you take on your phone; it connects to your "Samsung account" if you create one. It also integrates with Dropbox to sync photos to the device Gallery; if you have "Camera upload" turned on in Dropbox as well, this probably results in your phone having two copies of each photo: the usual one, and one in CloudAgent's storage.

You can change its settings by going into the main Settings app and choosing Cloud from the Applications manager list (in the Device section). You can clear its data and disable it, or "freeze" the app if your device is rooted, and the only consequence is that photos from Dropbox won't show up in Gallery. If you have the Dropbox app installed as well, Dropbox can still sync (and automatically upload photos) without CloudAgent running.


How can I change my Asus Eee Pad's language from Taiwanese to English?

Use the icons.

First look for the settings app or icon (looks like cog wheels). Scroll through the list of apps in your launcher. You can also press the menu button while on your main homescreen and choose the settings from there (same idea - look for the cog-wheel icon).

Once you're in settings, look for the menu option with a little 'A' icon on the side - that's the one for Language settings. Press that.

Now press the very FIRST menu option to get a list of languages.


Minimal Internet usage on an Android phone

Depends entirely on how many contacts you have, how often they change, how often you set it to sync, etc.  Paying for data as you go is generally a bad idea with an Android phone, they use a lot.

You should be able to shut off 3G though (probably dependent on the phone) and just use WiFi.  Although, it might be more difficult to prevent it from using 2G data.  Some phones let you use WiFi while the phone is in Airplane mode, which would shut off both 3G and 2G.  Android has the ability to store WiFi credentials and connect automatically.

Google Account Log in doesn't work on LTE/Data

I had the exact same problem: Cannot log in to google account when on data (works on Wifi)

After contacting both google and my network provider, it was clear that the problem is on the device. For me there was a built-in security app from Lenovo, blocking 'google services'.

Check all your firewalls, antivirus programs and the settings>data that nothing as googleservices or googleframework is blocked. Uncheck 'restrict background data' in case it is enabled for all apps or google-specific. Also allow syncing data for apps while on data ofcourse.


kindly copy and paste the link into chrome and stay logged in to your account. Else link looks fine to me.


How do I get my rooted Incredible to install the latest Verizon update?

Are you running the stock ROM, only rooted?  If so, you have a few options.

RUU to the latest OTA & reroot.  Available Here.  (Requires Unrevoked 3.22)
Install a pre-rooted ROM.  Available Here.

If you're running a different ROM, you should be able to do a build.prop edit to keep from seeing OTA notifications (and burning your battery, redownloading the OTA constantly, etc.).  This post describes what needs modified.

Finally, you can flash a ROM based on the latest OTA.


How to stop Time Warner cable search on Firefox for Android?

Your issue is not related to Firefox but to your internet provider (Time Warner Cable). According to this site, it "hijacks" your browser's default DNS resolution failure behavior (also known as "404 page"), redirecting you to Road Runner.

Following this site instructions, you just have to go to Road Runner's preference page and disable the Web Address Error Redirect Service option then save.


Doogee S60 - Can't hide/change battery icon

The answer lies in build.prop!

All credit for this goes to Nephiel on XDA-Developers (this post, specifically).

The Doogee S60 has the setting battery_view_land_show, which is defaulted to yes.
On a rooted phone, this setting can be changed easily using BuildProp Editor.
Set the value to no, reboot the phone, et voila! Back to the standard battery icon, and all expected behavior from GravityBox and such!


Android devices shows up in wrong account on Google Dashboard

The default account is the one that you logged in with first. If this was your Apps account and the "Remove account" option doesn't work than on a non-rooted device the only way to remedy this I to perform a Factory reset. However the device will still show up on your dashboard, I have devices I stopped using two years ago still there.

One other thing to note is that your phone should show up on all accounts that you're logged in with. If it doesn't, try downloading a free app with that account.


Why does my Android phone download files slower over the same network than my laptop?

You seem to be using different measurement units, 50KBps is the same as 400Kbps. Remember that 1 Byte = 8 bits.

If that's not the case, check if your laptop is connecting using 802.11n, HTC Legend does not support 802.11n, it only supports 802.11b/g.

  How do I check the connection speed?

Download SpeedTest app from the Market. And in your laptop, go to speedtest.net.


No. This folder is not created by Android.

This is the folder created by the app named Super Backup & Restore. This app is used to backup Contacts, SMS, Call logs, and some user Apps. And to restore to any version of android.
During backup, it creates a root folder named SMS Contacts Backups, and with sub folders with each category: apks, logs, contacts, sms in the internal memory.
You can remove those folders after restoring.(Note: Also, you need to remove App(Super Backup & Restore), otherwise it again creates folder with same name.)


Timeriffic is fantastic for this purpose.  You can get the latest version from the app's Google Play store page, or you can get an older version from f-droid.org.

Reading NFC tags from the front of the phone

With the backing of dotVezz, summing up from the comments:

Considering the specifications, this is quite unlikely:

range of the NFC signal is limited to a max of 10 cm on "clear view" (see Wikipedia)
material with a greater density will reduce this even more: air ~ 0.001 g/cm3 versus Lithium ~ 0.53 g/cm3 makes rawly a 500-times-density difference, so a factor of 10 (as I mentioned in my comment) probably is a huge under-estimation
even calculating with a factor of ~10, this would reduce the range to below 1 cm. And you will rather have to more than double that factor.

With few devices being thinner than .8 mm, your wish is close to impossible of being fulfilled.


Meaning of version code name on Google Android ROMs?

Per this:

  ... the first letter is the release family (e.g. KitKat), second letter is the branch code (Release or Testing), and the next three characters indicate date code (quarter beginning in Q1 2009, day number within quarter).


How can I ensure that I'm logged out of Google Latitude?

If you see "Join Latitude" then your latitude options are already "off". If you also now see "location sharing is not turned on", then your account is not set up to share the location information and it will not be sharing the information.

If you don't already, turn off wifi & gps when you are not using them, mpas will be less likely to try and get "pin point" information if you do not have these running.


Applications normally store their data in /data/data/com.foo.bar but you won't have access to that via adb on an unrooted device, by design.  I don't think there's a way around that without rooting the phone.

How to access the RecycleBin or trash folders and recover deleted files?

Android has no "Trash Folder". Maybe your file manager provides one but with no info provided, we cannot determine how it is. Usually unchecking such an option like "Delete Permanently" just disables file shredding, which is far different from moving to a "Trash Folder".


How can I delete data from phones that won't start up?

Preview Facebook Messenger's message on lock screen

I have noticed the same thing.

It appears the latest Facebook updates have actually removed the feature as there is no setting in the app for the lockscreen.


Unable to get output buffers (err=-38) when attempting to screen-record emulator from ADB

From ADB documentation :

  "Some devices might not be able to record at their native display
  resolution. If you encounter problems with screen recording, try using
  a lower screen resolution."

Documentation link :
https://developer.android.com/studio/command-line/adb.html#screenrecord

Try to use the size option :

  --size widthxheight

  Sets the video size. The default value is the device's native display resolution (if supported), 1280x720 if
  not. For best results, use a size supported by your device's Advanced
  Video Coding (AVC) encoder.


Samsung Galaxy S4 USB Not Recognized by Windows 7

After searching the Internet for similar issues, I did the following:

I unplugged my phone from the USB cable.
On the home screen, I pressed the bottom left Settings button and chose Settings.
I selected "... More".
I pressed "Developer options" in the list below.
I turned on the Developer options at the top.
Under the Debugging section, I checked "USB debugging".
I reinstalled Samsung Kies.
I started Kies.
After Kies started, I plugged in my phone to the USB cable.

After connecting my phone with Kies running, the Windows Update form appeared and a new entry was in the list.  After the driver installation, everything worked.  I don't even have to run Kies first before connecting my phone to get Windows 7 to recognize it.  It just works.

I don't know exactly what series of events caused this to start working, but now I can actually copy stuff to and from my phone.  (Yay!)


How to extract ZIP files on SD card via MTP from Linux?

In order to unpack a ZIP file that's located on your phone, you can make use of the unzip command, which is included in BusyBox. To execute it, you can either install a Terminal emulator on the phone, or use adb from a computer with your phone plugged to it via USB.

ADB method

Before plugging your phone to the computer, make sure that the checkbox near USB debugging, located in the Developer settings, has been selected.

Next, plug your phone to the computer, start a shell on the latter and install ADB, which you'll use as a means to execute commands in your phone.

After the installation is complete, start ADB by issuing adb shell, which will trigger an authorization dialog on your phone's screen. Accept it, and focus on the newly issued command, since you might have noticed that a new, differently prefixed shell has taken your previous one's place on the computer: you're now commanding your phone.

Now, from the ADB shell, cd to the directory where your ZIP is located, and create a new directory with mkdir Directory (replace Directory with a name of your choice).

Finally, issue unzip archive.zip -d Directory, replacing archive.zip with your archive's name; the contents of the archive will then be extracted to the specified Directory.

Should you find too much output cluttering your shell, replace the unzip command above with unzip archive.zip -d Directory &> /dev/null, which will silence the command.


I found a solution:
If you don't have a RMA option like me, it's possible it can be fixed with just disconnecting and reconnecting the front facing camera.

Try deleting cash, reinstalling camera, safe mode, factory reset, etc. before doing this.
Proceed at your own risk!

As shown in this video: https://www.youtube.com/watch?v=OPuCmfhzgbg)

Remove the back of the phone (beginning of the video).
Unscrew the top plastic plate (7:15 - 8:10).
Disconnect and reconnect front-facing camera flex cable (13:43 - 13:57).
Put everything back together and you're done.

Viola!
I hope it helps someone.

UPDATE: It stopped working again and this didn't help anymore. I had to buy a spare part and according to the video above replace it. The repair was succesful though.


Smart Lock unreliable/not working with NFC tag?

This is a known issue, https://productforums.google.com/forum/#!topic/phone-by-google/DyxZwJpsOwY & https://issuetracker.google.com/issues/62268615.

In addition, the NFC Smart Lock feature has been removed from 7.1.2 (I think that was it) and is still gone in Android 8.0.0 Oreo.


How do I synchronize my FireFox Bookmarks from my PC to both my android devices?

By far the easiest way to do this is to use Firefox as your web browser everywhere, and then use Firefox's built in sync functionality. This will (optionally) sync not just your Bookmarks, but also your History, your Saved Passwords and your Preferences, and let you see the recent tabs you've had open on different machines.

Start by installing Firefox for Android, then on your PC go into Firefox's Options, click the Sync tab and run through the wizard to set up sync and the encryption key.

Then open Firefox on your Android device and you should see a prominent option to set up sync that will involve copying a short authentication code between your phone and PC copies of Firefox. After that it will start pulling all of the info down from your PC to your phone (you may want to make sure you're on wifi for this first sync).

For a clearer guide, with pictures, see this page on the Mozilla support site How do I sync Firefox between my desktop and mobile?

cant get my emails over a month old even though i didnt erase them

If you are using the Gmail app or the default email app, you can set the timeframe in which you want to sync emails by going to Settings > [youraccount@gmail.com] > Days of mail to sync (default: 30). Increasing this value will give you a longer history of your emails, but keep in mind that syncing emails over a large timeframe may take up significantly more storage space on your device.

Note: the wording for "Days of mail to sync" may vary depending on which email app to use.


How can I increase the brightness of photos on the HTC Wildfire S?

You can access advanced options to better configure your photos outcome and maybe improve them on that particular environment.

Open the menu panel to access and change camera settings:

To open the camera settings, while within the Camera application, press your device "menu" button.

Available Options:

Image adjustments

  Slide your finger across each of the slider bars to adjust the
  exposure, contrast, saturation, and sharpness.

White balance

  White balance enables the camera to capture colors more
  accurately by adjusting to your current lighting
  environment.

ISO (photo mode only)

  Choose an ISO level or set it back to Auto. Higher ISO
  numbers are better for taking pictures in low light
  conditions.

Auto enhance (photo mode only)

  Select to reduce noise when using a high ISO setting and to
  automatically adjust photo brightness.

These are the most relevant settings to play with in order to obtain better results to your current scenario. You can read all about this and the remaining available settings on the users manual for your device under page 86.


Where can I see what the screen dimensions are of an Android mobile phone

Here is a chart with most devices specs to help find the resolution. Source matt :)
in a response on what-size-should-images-be-for-android-wallpaper?


The "While locked" or "When device is locked" menu is missing in settings

Go to Security settings and select "screen lock". Create a lock (even if you have one already). After confirming the lock, you will be asked to change how your lock screen notifications are displayed. Change according to your liking.


Vibrations or not depending on phone position

You could do that with Tasker. This app matches defined conditions with tasks -- i.e. you can tell it to execute a task (which is a set of actions) whenever a (set of) condition(s) is met.

Under conditions it lists "Orientation".

As actions, it e.g. describes:

  Vibrate On Notify: Whether to vibrate with a system notification.
  Vibrate On Ringer: Whether to vibrate on an incoming call.

So you could create a task named, say, NoVibrate, which says:

Vibrate on Notify: Off
Vibrate on Ringer: Off

Then create two profiles FaceUp and FaceDown (there's no "OR" connection possible with conditions, hence you need two profiles), each with the respective orientation, and have them execute the NoVibrate task.

What happens then? As soon as the phone is FaceUp or FaceDown (where "face" is the display), vibration is turned off. And as soon the orientation changes, the prior setting gets re-activated.

Problem solved with the 6-letter-solver of (almost) all Android problems: Tasker :)

Android - Limit app permissions *before* installing app

You can't change app settings before the app has been installed.

However if you are concerned about data leakage I would do the following:

Download the apk to your device
Disable all network connections
Install the app
Change the app permissions according your preferences
Open the app manager and select the just installed app
Force the app to quit and delete the app data and caches (just to make sure)

Afterwards you can safely re-enable network access

Anyway, for common permissions the app have to ask before it can be used the first time. Therefore it is unclear to me what permissions you are referring to that could be directly used without that you have explicitly granted access to.


With a rooted mobile ,Can I free up some internal storage (ROM) after delete some google apps from system

No. Deleting apps from the system does NOT free up usable space. System applications are stored in the /system partition which is not usable space to the user, you will not gain any usable space this way.


As of until Marshmallow, stock Android does not support connecting to both WLAN and Data network simultaneously.

You may keep them both turned on, but the OS will then choose to connect to WLAN or Data depending on Internet access and network quality.

Android has a Bookmark widget that supports individual sites, and a Bookmarks widget that will display all of your bookmarks.

It looks like you don't want to use the Bookmarks widget, but rather an individual Bookmark.

There are 2 ways:

From within Chrome: Bookmark the site you want to link to. Open the Bookmarks (via Menu > Bookmarks) and long-press the one you want to add. Select Add to home screen
From the App Launcher: Go to Widgets and find Bookmark (it looks like a red flag with a star on mine) and add that to your home screen. You can then pick whichever bookmark you want.

Either way results in a direct link to the desired bookmarked website.


I can't find the developer options in my tablet running Android 4.0.3

http://m.androidcentral.com/how-get-developer-settings-galaxy-s4

Head into the Settings menu. Samsung's done things a little differently and changed the way the settings menu looks, so you'll need to hit the "More" tab, and then get into the Software information.
Look for "About device" at the bottom. Tap it.
Hop on down to the build number, and tap it seven times. One. Two. Three. Four. Five. Six. You'll get a little prompt saying you're about to unlock the developer settings. Hit that button one final time -- seven! -- and they're unlocked.

Have you tried this? Its really a bit tricky.


How can I turn off speaking of incoming caller?

Well, what you can do us head over to the Settings>Accessibility>Vision>Tap over Talkback>Tap on Settings over the Talkback window>Uncheck speak caller ID, that should fix your problem out.


Does Chrome's reduce data make browser faster?

It depends on the pages. If the pages are media-heavy (lots of large images or other media) then yes, the pages load faster since Google scales and recodes the images on the servers before sending them to your device, and optimizes other page content also. However, the device still needs to render the layout of the page, which can be slow on mobile devices. This happens on the device and requires CPU+RAM, and is unaffected by the bandwodth optimization. Also, since some content is compressed when sent from Google's optimization servers, it needs to be decompressed on the device, which uses CPU.

All in all, reducing data helps move the bottleneck from the bandwidth to the device itself, and the benefit of the setting depends on the content of the pages and the performance of your device.


How to choose a firmware before downgrading Andriod version?

According to this site, this is for Region XEO, which would be Poland, located here.  You can't just choose any version and have it work, and Samsung is known to not allow you going backwards in firmware versions due to a lock in the bootloader preventing this.  You may be able to go back to 5.1.1, but most likely not 2 Android versions backwards, and even going back to 5.1.1 may not be possible.


Accidently wiped out all data. Now I can't restore it.

Well, I haven't had this issue, and I'm not experienced much.

If you plugged it into your computer, opened KFU (not sure if it'd detect it), you can download the latest stock ROM. Then maybe all you'd have to do is push it onto the SDcard through ADB? and then reload TWRP (or something to refresh the list) and it'd appear, and then you could flash it?

Not sure if that'd work. Again, not an experienced person with this, but maybe you can figure something out with my idea. :P


Play Store (web) doesn't show my device on my default Google Account

Error RPC:S-5:AEC-0 is known issue and many are facing the same issue as you. Check: Google Play Error [RPC:S-5:AEC-0]


Per this link you can create a profile that defaults to phone silence and changes the ringer to not silent when someone you want to take a call from or is not a person you blocked and then when someone you have blocked calls it will answer the call and hangup.

Here is a summary

Create new profile Allow Calls
Add context --> State --> Incoming Call

Specify who to allow calls from (ex. C:FAV (for favorites) or !)
"!" reverses logic (such as is not contact) and 0 can be used for anyone calling from a restricted or unknown number

Add Task --> Audio --> Ringer Volume

select ringer level (7 is highest)

Add Exit Task --> Audio --> Ringer Volume

select ringer level 0 (to silence the ringer once the phone call is done)

Create new profile Blocked calls
Add context --> State --> Incoming Call

Specify who to block (ex. !C:FAV (is not on favorites)  "0")

Add Task --> Phone --> Take Call
Add Task --> Phone --> End Call

This should allow your phone to ring when a favorite is calling and pickup and hang up on someone you wish not to talk to without you even knowing.


Reverse Tethering won't work for me - is it because my phone isn't rooted?

Yes, you need root:

$ netcfg usb0 dhcp
netcfg usb0 dhcp
action 'dhcp' failed (Permission denied)
$ su
su
# netcfg usb0 dhcp
netcfg usb0 dhcp

action 'dhcp' failed (Network is down) <-- I used 'netcfg usb0 down' from another terminal here
#

The only way I've personally seen to accomplish this without root is to basically have some sort of proxy server-esque application on your computer that communicates with an app on your phone using ADB's port forwarding. It's not especially reliable from what I've tested out (we were looking for a solution like this for a client at work), but you can give it a shot. You can take a look at this app/thread on XDA, or this CodeProject page for a start, although I'm not sure that either of them provides truly transparent internet passthrough.


Can't find shortcuts for downloaded apps

Creating that shortcut is done by the Google Play Store app, which has a setting for that. So:

start the Google Play Store app
go to its settings page
check the setting for creating shortcuts (and enable it).

I currently can't tell you what exactly that item is named (I have no device with Google apps installed available at the moment), but it should be easy to identify. On the other hand, there's always a Google Image search :)

Is there a way to view the file size of an image without downloading any apps?

Is there a file manager called "My Files"? Most Samsung phones have that by default now, although I'm unsure if Vanilla Google Android on the Nexus S will have that. Check file size through that.


How to properly play 720p/1080p media with subtitles through MHL (HDMI out)?

If you're rooted you could try to force a certain combination of phone screen resolution and DPI using Second Screen and maybe your selected video player will conform to that even as the video is being streamed out through MHL.

Just make sure you keep failsafe options like "don't keep settings after restart" enabled in case your experimental Second Screen settings make your screen unusable.

skip whatsapp restore on temporary phone but keep files for restore on next phone?

No.  If you want to do this, you need to first go to settings in Google Drive, go to apps and disconnect whatsapp.

Then skip the restore.

It automatically overwrites your old one.

I had the same situation, followed the advice in the first comment and lost 1.7G of precious data including many pictures I have saved nowhere else :(


Your phone's internal storage is not the SD card, it's the internal partition where all apps and app data goes to. There's an automatic decision to put excessive data somewhere else (the SD card) if an app is too big. Your app was already installed to the SD card and you therefore have an option to move it back to the internal storage.

There are mainly the following sections:

/system - The firmware sits here. Write protected.
/data - all apps and app data goes here.
/mnt/sdcard - This is your external sdcard. Also referred to as external storage
There are some other but the above 3 are the most important/interesting ones

If free space in the internal section (/data) is low, Android allows to move certain apps/data from /there to the SD card to free space.


You're probably not going to like my answer, but I don't think there's anything you can do about it. I've tried to turn this off myself in the past, but the Android OS is such that you will receive a force close vibration no matter what. Now, regarding your application actually force closing, here are my two best guesses (since I can't see any of your code):

You are trying to use a feature that requires documentation in the manifest file.
You are overburdening the UI stack by not threading processes that take a long time to accomplish (i.e. contacting a server and receiving data, handling remote data, etc.), which can be solved with AsyncTasks.

Also, if you are getting frequent force close errors, please use DDMS. It's an absolute God send for this kind of stuff. I know a lot of people who just try to "figure out" where they went wrong. Debugging is a skill in its own right.

Sorry I couldn't directly answer your question. I instead tried to pinpoint where else you may be going wrong with your applications, which, to me, would seem to be a bigger issue.

EDIT:

To show you how I arrived at this conclusion:

I firstly tried to look through all settings (including my Galaxy S manual), and obviously no cigar.

I noticed that there are two classes that a developer must look into to at least see if this vibration can be turned off programatically (for your specific program). These classes are the Notification and Vibrator classes. Upon inspection, you can see that there's nothing within these classes that will allow you to do that. It's a system property. Realizing that you must put in a "vibration" intent into the manifest in order to even manipulate the vibration should further prove this point:

    <uses-permission android:name="android.permission.VIBRATE"/>

I wasn't really prepared to mess around with the actual Android low-level code so I brought the issue up with my friend (who has been messing around with the actual Android kernel and OS itself for a while) in order to validate my suspicion. He said that this property was built in. In other words, you would have to override the property within the OS itself in order to change the force close vibration. For me, that was the end of me trying to turn off this property.


Okay, somehow or the other, I got it to work using tips gleaned from various links from Googling 'brand new Galaxy Nexus not booting'. I haven't figured out the issue, but I had the phone plugged in without the battery and inserting the battery then showed me battery charging image on the phone for the first time, but it quickly died out and I couldn't start the phone. After subtly pressuring the battery randomly, I got the charging screen back and switched it on.

Some of the posts in the aforementioned Googling suggested there might be slight defects in the Chinese-made Galaxy Nexuses (apparently it was made in both Korea and China), and mine is made in China. It might have to do with the battery not getting placed just right. I suggest to anyone facing similar issues to try to see if there's any effect with inserting the battery with the phone plugged in as I did in my case.


Why are portrait photos sometimes sideways?

I found the answer to my own question.   It seems cameras take the picture and then store an flag, the Exif orientation, rather than just storing the rotated data, because the latter would be too time-consuming or it would be too expensive to give the camera custom hardware. (https://www.impulseadventure.com/photo/exif-orientation.html)

But not all software supports these image rotation flags, so it's best to process images when importing them to convert them to an image with no rotation flag.  Some tools for doing this are here:

http://how-to.wikia.com/wiki/How_to_auto-rotate_digital_photos_to_their_proper_orientation

The exifautotran script seems to work for me, e.g.:

exifautotran *.jpg


No. There's no way you can prevent it. It's a security feature implemented by Google as pointed out in comment

If security can be relaxed there is no security

In your case with people joining in and leaving all the more reason - think of it as you are running a small company with employees using a common mail account - you wouldn't want unauthorised access

That it's a low value account to you is not relevant given that it's your account and Google security policy rightly does this

You can flash the Open GApps package as I found that to work for me best.

Today I read that flash write performance diminishes with use. I'm a heavy user. Should I change my behavior?

As a user, and not a developer, this is not an effect you should concern yourself with. For operations like disk defragmentation or use of flash memory as virtual memory, the sustained high disk write rates can wear out flash memory quickly. But "normal" usage by a human will not produce enough writes to create a wear issue.

Let's take the sleep app as an example and estimate how many writes this will cause on a wear-leveled disk. Suppose the app collects 128 kilobit / second audio to store uncompressed and runs and collects audio at all times for 5 years. (128 kilobits / second) * (128 bytes / kilobit) * (5 years) * (365 days / year) * (24 hours / day) * (60 minutes / hour) * (60 seconds / minute) ~= 5.17 * 10^11 bytes. On a wear leveled disk of 1 GB ~= 10^9 bytes, this will be (5.17 * 10^11) / (10^9) ~= 517 cycles over the 5 years, which is well below the expected 100,000 cycles for current flash memory.

Also, note that almost all SSDs are currently built from flash memory, so there is no significant difference between the storage for your Android phone and that in a consumer SSD for a laptop/desktop in terms of expected aging issues.

EDIT

If you are really worried about this, I would benchmark your storage performance. I don't think it is a good assumption that erase/write operations take 0.6 seconds; your flash memory is not the same as that used in the example figures.

This empirical evaluation of flash memory gives actual figures for degradation. The magnitude of the effect is not that large for cycles in the low thousands.


How do I send this explicit intent from Tasker?

Here is how I fixed it.

Lock screen shown when notification selected

If you have any custom lock screens, un-install them. This will make the annoying behaviour stop. At least it did for me. There was some funky systems settings between the lock screen app and next launcher that you get prompted for. This made the default lock screen come up (not the one I was trying to use).

To recap, this happened with the NeXt launcher (very good, btw), Go Lock Screen and stock android 4.1.1 unrooted on the Samusung Galaxy Note II (Rogers - like AT&T).

Hopefully this helps someone pin down the real reason this happens.


As the comments above suggest, you may have to check your time zone in Settings. On stock Android, it can be accessed under System > Date & time. The best thing to do is to select "Automatic time zone" if you have a cellular network connection; this will automatically set your time zone for you. If you can't, you should set in manually under the Select time zone option. If your time zone is correct, then it could be the app that is displaying the weather instead; uninstall it and reinstall it, and see if it is fixed.


i noticed all the rooted MZ601 roms, have poor OTG support in the kernal, or next to none, i had the same issues with eternal USB DAC, not been recognized since the 4.0.4 stock ROM, after spending weeks , blowing images, roms, went back to the stock ROM 4.0.4, seems OTG support is not on their high list to things to do, only external USB hard discs.

the USB DAC is only 4 months old, so its not some special kernel patch, as the 4.0.4 is over 2-3 yrs old and worked, try going back tot the stock rom.


Gmail app on LG Optimus U doesn't get email anymore

I've had this problem before.  Sometimes the "unread" count goes up as well, but the emails never show in the Inbox.

The best thing to do to fix it is to go to Settings -> Applications -> Manage applications and clear the data for Gmail and for Gmail Storage, then to try syncing your Gmail account again.  If this doesn't work I recommend clearing the data for all Google apps -- Gmail, Talk, Voice, Google Framework Services, etc. -- then rebooting and trying to sync your account again.

Is tethering/hotspot dangerous for your Android phone?

There isn't enough/real evidence suggesting that tethering is harmful to device hardware. AFAICT this is a feature-by-design that any android device (supporting tethering) should be able to handle without detrimental effects other hardware except perhaps that the battery may be degraded a little bit due to overheating.

(Just like using your PC to play high graphics games 24/7 with a gaming PC, even though the PC seems to be "overworking", you'd agree with me that's what its designed for. Isn't it?)


ADB_SERVICES error on catlog errno = 5 I/O error

Enabling GPS flag on android preferences: what is the battery impact?

Normally your battery life will be the same. Only if applications start requesting GPS updates the battery will be affected. The switch from the Power Control is just a shortcut to prohibit / allow applications to enable GPS location updates.
