Welcome to Android Central! Does this persist after a reboot? If so, then you could also try wiping the cache partition. Follow the steps in this video, but instead of selecting Wipe Data/Factory Reset, make sure you select Wipe Cache Partition. When complete, then select Reboot System Now.

I have similar problem on my tablet. Restart usually helps. Unfortunately I did not found better solution.
