Why do I need to keep restarting my device?

[AC Question]

Most of the time when I continuously use my mobile phone more than one hour it gets of at its own and I have to restart the phone

Hi and welcome to AndroidCentral.

What device do you have?

What apps are you using?

Has this always happened, or is something new?

Have you tried wiping the cache partition? Please see this guide from Ambassador Javier P. http://forums.androidcentral.com/ambassador-guides-tips-how-s/558872-guide-bit-cache-clearing.html
