I have a couple things that I am kind of wondering about concerning the screen. First I have the brightness set to like 30-40% but there are times that it seems to fluctuate, if I open up a few menus that have a white background it starts out kind of dim but then will brighten up once I start to scroll through them, kind of like when the phone is about to go to sleep and it dims down for a second but if you touch it will brighten back up. Doesn't do it for everything but enough stuff to be kind of annoying. Second is, does anyone have trouble with severe color banding? I thought these screens where 24bit with 16m colors but there is a lot of apps and things that show lots of bands. One off the top of my head is the weather channel app, the blue background has it super bad. Do I maybe have a bad screen?
