Samsung Galaxy Core Prime restarts itself when I try to unlock it?

[Android Central Question]

I was using my phone last night and I fell asleep and it died. When I woke up this morning I plugged it in and turned it on. It booted up normally and was still responsive, but the weird part is that when I tried to unlock it, it would freeze and just restart by itself.

Any help?
Thanks.

Welcome to Android Central! How long did you let it charge for? Make sure it's charged fully (i.e., let it charge for at least 6 hours undisturbed), then power on again.
