information about your Android device. The question is, do
you always have problem with your Android device? Is the

device because of virus, application error or bugs?
Regardless of the problem your Android device might be

Useful Android Secret Codes You Should Know

codes
Or manually follow the information below;

about your phone and battery. It shows following 4 menus
on screen:
