Hi everyone. I had this issue today. I replaced the screen and the phone went crazy. First, it takes about 4 minutes to start. After that, it says home button needs servicing( it works if I remove the front camera flex). However, I still have touch ID function working. Then, opening apps is very, very slow. Once started, they work properly. Speaker is not working anymore( can't use Voice Memo) and I have no idea why- I'm blaming the software.
I did everything by the book, in the lab. All parts were removed with extreme caution, nothing fell, batery was previously removed (I never replace anything with the battery attached to the phone). The phone is a 7 Plus with a broken screen, OS11. I restored and updated to 11.0.1 but I still have the same problems. Question is, can I downgrade to 10.3.3?
