Replacement lightning port and screen works…sorta. Need help!
I recently upgraded my phone and want to give my old one to my grandma so I decided to change the battery, lightning port, and screen just to kind of refresh the phone. I managed to replace them all, I made sure all the connections were seated in, no missing screws, but when I plugged in a charger, the phone turned on but the battery indicator was all the way down and not showing percentage or charging status. I also noticed that the motherboard seemed to get a bit hot . Another problem was the home button Taptic feature didn’t work but it still functions normally. So I took it all apart and put back the oem lightning port and screen and now the battery shows it’s charging and it’s at 66% but the home button Taptic still didn’t work. So is the replacement port bad? Is my Taptic Engine broken? Did I mess something up? Any help is greatly appreciated!
