Chosen Solution
So several months ago I had dropped my onePlus one and cracked my screen loosing all touch capabilities on the bottom 2/3 of the screen. After getting by using a microUSB mouse I decided the best solution for me was to fixit my self thanks to this website. I was able to successfully replace the screen and didn’t have any problems with my phone for several months. However, over the past 2 months it has began to have a very annoying Ghosting problem that seems to come and go but has gotten bad enough I have had to apologize for phone calls I didn’t make and delete pictures I didn’t take. From my research and experience on the issue I’m still uncertain if this is a hardware or software issue. It does seem to be worse if my phone is hot from intense use or very visually intense apps but that is the only clear connection I have seen. Any advice on how to resolve or troubleshoot the issue is welcome and appreciated. Thanks for you help.
Had and still have the same problem, certain cause for this is that screen replacement is glued to the midframe, unlike the original one which is double-taped.. as you said, heat does play a strong factor considering it heats and evaporates the glue causing these touch sensitivity problems.
