colour loss I think after last update...brightness of screen is dim like....it can solve by next update only....but if you don't post any screenshots then we can't understand that it's display burn in issue or something....because if it is display burn in issue then only way is to change the display no other option for s amoled screen
last update i did it from the service centre itself.So it was properly done.And it just happened suddnly.My phone did not fall down or there is no physical damage or water issue..How to fix it ???.i will post a display image of it for your reference.
I think there is no problem in this...because I am not able to notice any fault in this immage....anyway do one thing ...go to display settings then tap on dark mood option...then check whether apply dark mood on wallpaper option is on or off ...if it's on then switch off it.....but I can assure you that last security patches of s9 series have that bugs because I can also feel brightness of display is not up to the mark ...it's looks like dull images only...regarding that I launched a complaint already
your device iris scanner is ok?I am facing a typical issue ....when I am taking a photo by builtin camera app then trying to unlock my device with iris scanner..then the area of iris turning into dark blackish pink...this issue overcomes when again I I restart my device
