Galaxy fame continuous restarting

[leobeckstars]

My samsung galaxy fame is continuously restarting itself.
I tried to factory format and cache format but it continues to do same. What should I do?

Check to see if its the phone itself , Because i had a similar issue on a galaxy s3 mini, when i would move it to fast or tap the back it would restart

Welcome to Android Central! Try reinstalling the firmware using either Samsung Kies or Samsung Smart Switch. If that doesn't help, it could be a hardware issue (either the Power button or the motherboard).
