Is there a way to find age of an Android device

Question

I want to find out how long the device has been used. I dont want the uptime i want the actual time elapsed from the device first boot

Answer 1

you can try:

Log.i("ManuFacturer :", Build.MANUFACTURER);
Log.i("Board : ", Build.BOARD);
Log.i("Diaply : ", Build.DISPLAY);
Log.i("Time : ", Build.TIME);

Unfortunately the Build.TIME will be reset when new ROM is installed.
