Recently bought a New 3DS off eBay, specifically the Black Friday limited edition Mario one. Its in basically perfect condition however I was so blown away by the physical condition that my eyes completely glossed over the pictures.
Fast forward to yesterday, I got it, and turned it on only for the bottom screen to be weirdly bright?? Even when fully black, it ends up being more of a bright grey. I also noticed that it was getting Ui elements burnt into it really easily. I thought it might be a burn in problem so I ran SPF (Stuck Pixel Filter) on it for about an hour and it was gone!
I thought I had gotten rid of it, however once closing the lid and turning it back on again the brightness came back.
Redditors with more hardware knowledge than me please help me out here 😅🙏
