I broke my OnePluse 9 5G screen

@thepsychonaut it’s a relatively new phone so you will have limited information available. For now use the youtube videos available but as always, proceed slowly and focused. Watch the vidéo a couple of times beforehand so you are comfortable with it. I also find that by reading any comments left, it might inform of any shortcomings etc. While you are changing your display, take lots of pictures. After you have successfully changed your screen, create a guide for the rest of us https://www.ifixit.com/Guide/new

OnePlus is actually offering repair out of warranty which is reasonable. If it is just the screen, then it is $206. Not many have seen this. https://www.oneplus.com/support/repair
