Hi, I have a problem on my m2s. When I opened my camera app in a dark room, or any games that have a black background, I can see 2 small dot pixels on the center left side of the screen displaying a bright blue color where it is suppose to display black. Weirdly, the same pixels will display correct color for other background color. So it always happen on black background. Anyone of you have the same problem? Can it be fixed by software?
