Welcome to Android Central! Try restarting your phone and seeing if the glitch goes away that way. Have you downloaded any launchers or other apps recently? Does this issue persist in Safe Mode?

Okay! Try seeing if the issue persists in Safe Mode. If it doesn't, then it's likely that you have an app that is causing the issue.
