I was playing a game on my phone then suddenly the whole screen started going random colours and then my phone screen turned off when I re opened it too my shock I could only see a little bit off the top of my device so how do I fix it because the entire thing is completely ok I can use it just I can only see the top of my phone the rest is just black.
Hi, Sounds like you may have a damaged display. If you have done a hard reset and the issue still persists you’ll need to get it replaced either via DIY or a professional repairer.
