I have the NEW Taptic Engine fitted but the problem still exist. Is that possible that it can not receive the proper voltage so the vibration is not that intensive? What is the right way to diagnose this issue on the Motherboard?
Are you still trying to fix this issue? You have made sure it isn’t a serialization problem? Try and find the original serial number for the taptic engine with 3uTools. Copy it and write it to one of the other engines you have.
