My Samsung Galasy S3 I9300 model restarts automatically

[newbie2013]

I have a Samsang Galaxy S3 version I9300,bought it 2 months back. It was working perfectly until now when it switches it self off and restarts automatically randomly, no updates downloads,the phone is simply on the table , battery is good and suddenly I hear it restarting itself. Anyone know whats the issue here? My phone is not rooted and I prefer not to, also do not trust the Samsung repair guys and will prefer to resolve this issue myself unless I absolutely have to take it back to the service center. Anyone had similar issue? Plzzz help..

Hi. I guess there is some app that takes up a lot of memory , so to clear the cache may be your phone is getting rebooted. So search the app which is doing so. Or another option is to go for Factory Settings. I was facing a similar issue with my old Galaxy note and I restored my phone back to factory settings and my problem was solved. You can try this out.
