Navigation problems

[celts17]

So I got my s4 on august 25th, and everything has been great. Tonight, however when I was using the 3d map on the nav there were small squares on the screen that had a series of colored lines on them. Also, the map was responding very slowly. I turned the mmi off, and back on, and this didn't resolve it. Anyone else have this problem???

Its possible the GPU in the nav went bad. Thats sounds like what usually happens when a PC video card goes bad. I noticed the MMI system display is now powered by an NVidia graphics chip, probably somewhat similar to their desktop ones.

it takes longer for the software to come up ,I noticed on the 3g just do a master reset on you MMI settings.
