Question [Q] Display problem

I don't know what's wrong with my 6 month old GN3 SM-N900! But all of a sudden the display got divided into 12 screens(3x4) of same homescreen! The touch and everything is normal! Nothing except rebooting (by removing the battery) fixes the problem! My friend's GN3 has the same problem the other day! Sorry that I couldn't get a screenshot as I was terrified! Is there a fix? Me and my friend are up to date with the OTA updates!
Thanks in advance
