I had to change the bluetooth antenna of my iPhone 11. Everything went smoothly, and when I plugged in my screen, for a moment everything seemed to work perfectly. After about 30 seconds, I noticed some ghost touches on the iPhone screen. I figured that the connector might be a little loose or something, so I shut off the iPhone, checked the connections and turned it back on again. Now I saw no ghost touches, but rather the upper part of the screen didn't work at all. I repeated the previous step, and everything got worse: 2/3 of the screen stopped working, from the top to the bottom. I happened to have a screen replacement, and tried that: same result. Now I get no screen feedback - the screen works, is bright and all, but I can't press anything, unlock my phone etc. What might be the problem?
