Help Notification panel putting phone to sleep

[Dr Poiuy]

My AT&T S5 just updated last night to lollipop and now when I look at my notification panel, even if I'm actively touching the screen, the screen timeouts and goes to sleep after just a few seconds.
Extremely annoying! Any ideas?

Sounds like you need to boot into recovery mode and first try clearing cache partition. If that fails I'm afraid you'll need to factory reset

Oh no! That does not sound good! :-(

Can you give me instructions? I've never really played with my phone systems.

Thanks!

To boot into recovery, turn the phone off then hold in Power, Home and volume up until the Samsung screen appears and phone vibrates then let go and this should take you to a screen called recovery.
There you have to use volume buttons to navigate to Wipe Cache Partition then hit the home button to select it (use the power button if home doesn't work).
Then navigate back to reboot and select that.
Wiping cache doesn't wipe anything important.

If this doesn't fix the problem I think you're gonna have to do a factory reset (this wipes the whole phone so backup everything important to you)
