  The recent evolution on the smart phone technology has made its application
market huge and less secure. Every single day large number of apps introduced
in the android market (mostly on google play store) without any particular
inspections which creates a lot of security issues and they remain unresolved.
There are a lot of recent and increasing security issues which are mostly
caused by the android apps. Mainly, the access of user data through the apps
relied on the users given permission to apps.So, it is always a big question
that how different apps on the android smart phones bypass the android
permission model to have root access and how user data compromised or stolen by
its apps. It is not startling that the Google Play Store has massive number of
malicious apps that may gain users attention to fall victim for one, but some
time it might be even worse than we thought. In this paper, we will look at the
security issues (i.e. rooting phone, malware bypassing and secondary storage)
and how easy to get access to users phone by using its app.
  Furthermore, I will discuss the android update mechanism and its
functionalities as well as vulnerability to possible third party bypassing and
root access. Moreover, a key feature and source of the all possible access
route to android applications I will discuss an android permission model.
Finally, I will first time present concept of the feature based development
model implementing a feature based permission selections as a solution to
android application system and describe the purposed Feature based permission
model in detail how it is the solution for current security issues caused by
intentional (evil coded) or unintentional (poorly coded) coding using android
permission models.
