Help Screen flickering

So I noticed this morning that when my phone is turned off of brightness that it flickers in the background.

How do I go about unrooting so that I can exchange my phone due to this problem?

Sure it's not the auto-brightness in action? You can try disabling this feature, and see if that makes a difference:

[Menu] > System settings > Display > Brightness > Uncheck [Automatic brightness] > OK

run 'wipe date/factory reset' from the recovery

then 'apply update from external storage'

and 'reboot system now'
