I am along with several other people facing issue with the screen. When the brightess levels are changed the screen fluctuates and also the color is bit dull. When brightness is in between 20 to 60 percent, this issue is clearly observed. There are horizontal lines observed as well and this is creating unwanted viewing experience. Also while watching any movie or picture, whenever black color appears, that color is distorted and it looks like squares (depixalated). This issue is also known as black clipping. You may check internet with keyword 'black clipping on samsung mobile. Also to confirm, this all started as soon as warranty period expired and after the update.
