Constant Reboots on Lumia 521

[Jim Powers7]

I have a Lumia 521 that is constantly rebooting. I installed the Stop Restart App but the App says the phone is ok. Does anyone have a suggestion. Thanks!

Like the 520, the 521 has battery fit issues.

Make a folded paper shim to place between the bottom edge and the well in order to push the battery up against the contacts and another to go between the battery and the back to help hold it in the well.

Thanks, I'll give it a try
