I've had my note 2 for just over a week now and it's an incredible phone, however i'd like some input on a potential issue. I have my screen brightness on the lowest setting (not a lot of sun here) and I'm sure it didn't do this on the first few days but the screen seems to shimmer a little. This is most noticeable where there is a white area of the screen surrounded by darker elements - and is less noticeable/not noticeable on higher brightnesses. Battery charge level appears to make no difference. Is this a problem that has come up at all before?
