Haptic enginge rattles once and stops
This is the 2nd iphone X I have seen with this problem. The vibrate function isn’t working. It makes a loud rattle sound and stops. I have replaced the taptic engine and the dock unit but still the same. The phone was lightly water damaged. Screen didn’t work what I replaced but everything else besides the vibrate function works.
My experience with repairing iPhone X is limited so I hope this doesn’t require microsoldering.
