Lumia 521 Not Waking From Sleep

[SteveMobbs]

I've got a Lumia 521 on T-Mobile and once my device has been asleep for more than a few minutes the power button won't wake it up. Anybody else having this issue?

Try to remove battery and put it in again.

Yes, that works, but I was hoping for a fix.

Do you have this problem often?

Do you have this problem often?

Yes it's happened twice since the update. So twice within 3 hours.
