Text appeared stuck on my galaxy S5 screen

[Wickermuz]

i play a game and in this game u have a limited number of moves, which is displayed at the top right corner. when i exit the game, the word 'moves' still appears on that same spot and looks like it's stuck there. Reboot, uninstall the game, same thing. i haven;t flashed the phone coz i have a lot of stuffs.

Any tips will be welcome.

Cheers,
Muzz.
