iPhone 8 Plus vibrating vigourusly.
Hi everyone, I have an 8 Plus that I recently did a charging port replacement on. After the replacement, the taptic engine started to act up. The entire phone would vibrate very strongly and the mute switch would make a grinding noise. I replaced it with a new engine I got used from eBay and it still has the issue. Could that be an issue with the charging port? Thanks in advance.
