Freezing after unlock

[aliasunknown13]

Have a strange issue where my device will freeze on whatever screen I unlock it to (from a notification or just unlocking in general) after being locked for a couple minutes. I can hit the back button to "unfreeze" the phone, but it's really frustrating to have to do that every time.

Anybody have an idea of what may cause this?

Welcome to Android Central! Try booting into Safe Mode, which temporarily disables all 3rd party apps. https://support.t-mobile.com/docs/DOC-28008

If the problem disappears in Safe Mode, then something you installed is causing the problem. You may have to uninstall apps one by one until the problem disappears. If the problem persists in Safe Mode, then it's more likely to be a hardware or firmware problem.
