Several problems after trying to replace iPhone speaker
So I recently followed the guide for replacing the speaker in an Iphone 6s. Not only did I think everything went smoothly but it almost seemed surgical. Used every proper tool, every screw and component was kept track of, and I didn't force my way through anything. Although after booting there seemed to arise several strange problems.
1. During the first boot after the installation, the phone was stuck on the apple logo which I was able to get out of by hard resetting. Weird, but didn't think much of it.
2. For a few hours the phone was working flawlessly but then it stopped charging at a certain point. I tried different cables and outlets but nothing has worked so far. Now it only charges when the phone is off.
3. In addition, even when the battery does charge, it loses its battery extremely quickly.
I find this to be very strange considering I didn't even touch the charging port, or the battery for that matter.
CAN SOMEONE HELP ME OUT PLEASE
