Welcome to Android Central! That could just be corrupt firmware. If someone tried to hack your phone, they probably wouldn't want it to glitch out like that so as not to draw attention to the fact that it was hacked.

Try reinstalling the firmware using Smart Switch (http://www.sammobile.com/forum/showthread.php?t=29914) or Odin (http://forums.androidcentral.com/amb...interface.html).
