I fixed my screen a month ago and it has worked fine until today.Now the bottom half is not responding, but the top half is fine.Any ideas what is wrong?
stephanie_sk this “bottom half is not responding” is usually caused by a bad digitizer. Of course, you can try a complete reset and see if that resolves it. If it does not you may need a new display assembly. Of course it is possible that his is a deeper issues related to failure on the logic board etc. but I’d start with the easy stuff first. iPhone 8 Plus LCD and Digitizer Replacement
