  This paper addresses the problem of building an affordable easy-to-setup
synchronized multi-view camera system, which is in demand for many Computer
Vision and Robotics applications in high-dynamic environments. In our work, we
propose a solution for this problem -- a publicly-available Android application
for synchronized video recording on multiple smartphones with sub-millisecond
accuracy. We present a generalized mathematical model of timestamping for
Android smartphones and prove its applicability on 47 different physical
devices. Also, we estimate the time drift parameter for those smartphones,
which is less than 1.2 msec per minute for most of the considered devices, that
makes smartphones' camera system a worthy analog for professional multi-view
systems. Finally, we demonstrate Android-app performance on the camera system
built from Android smartphones quantitatively on setup with lights and
qualitatively -- on panorama stitching task.
