This is a copy of an error report i have just sent to Samsung. Also check out the article in the link I've included in this post. "The screen on my Galaxy Tab S7 Plus has started to flicker with a green tint, I noticed it at first when I had the display at low brightness. Now though the screen flickering is more pronounced at low too mid brightness level. I have researched this problem on line and it seems to be a fault not only on the Tab S7 plus screen, but it's a problem on the Galaxy Note 20 Ultra phone as well. I believe it's a problem only on devices using the Snapdragon 865 plus prosser. Can you advise if it's a software patch thats going to be issued, and if so when, or are Samsung going too have to recall the effected devices. Here's one article I found among the many i saw"
https://www.androidauthority.com/samsung-galaxy-note-20-green-tint-1150691/Is your device affected by this if so I suggest you contact Samsung, as this maybe a big issue for all of us & if we all voice our concerns Samsung is more likely to find a fix & not brush individuals off treating it as a storm in a teacup issue. I will post any updates to this i receive, Danny Caine.
