I just recently bought the DHD and was loving it up until the other day...when I looked down at my phone and saw this weird blotchy effect like suddenly my phone had downgraded itself to an old PC monitor...it started colour banding really really bad...when I look at my stored photos or even take photos with it, it seems like it has ridiculously bad resolution or something. its like the colours don't blend in with each other! theres no flickering lines and I haven't dropped it, so I don't know why suddenly it just started doing this. No new apps or changes or anything either...HELP! it looks horrible
