realmayank , via OnePlus 8 , May 21, 2020 : I bought this OnePlus 8 two days back and I am having this issue while playing games (such as Call of Duty or Free fire) or watching movies on Netflix or Amazon Prime Videos, the visuals appear darker. I tried increasing the brightness but it was of no use. the visuals seems like burned like too much of black ratio in it. I was previously using OP6 and videos works fine in it. I thought switching off the video enhancer might help but it didn't change the result. kindly assist. Edit: Images attached below: The first one is how display looks on OP8 and other one is from my previous OP6. I tried DC Dimming On/Off, Video Enhancer On/Off, but nothing worked. Today I called the customer care executive and he told me that it seems it is a Hardware issue and I should return the product.
