Chosen Solution
my phone is exhibiting some weird behavior. when i hold down the up or down volume to go to max or min volume, i can feel the taptic engine thumping away. once i hit max or min and continue in that direction, i also feel a thump. if i do a volume change one increment at a time (there are 16 of them), there’s no feedback. none of my other iphones (7 or otherwise) give me taptic feedback with volume changes. i’ve been inside and disconnected and reconnected all the flex cables, even swapped out the taptic engine. any thoughts?
Hi B C, My first suggestion is to try software solutions first. The things that come to mind would be to do a hard reset on the phone, try the Reset All Settings option in Settings, update to the latest iOS version, and finally try a full backup then wipe the phone and restore it. macReports has an article on iPhone System Haptics that has this to say about haptics and the volume button. Volume slider: Your iPhone has volume up and down buttons. You can use these buttons to control the volume. You will get subtle taps when you turning up or down the volume. If none of that does the trick and it is indeed a hardware problem, then the only replaceable part you have left to try is the lightning cable assembly. The Taptic engine connects to the logic board through that flex cable and since you’ve already tried replacing the Taptic engine, that only leaves the flex cable as a possible source of problems. I have heard that some Taptic Engines lose functionality when replaced unless data from the old engine is copied and rewritten to the replacement, but since your issue started before you replaced it, that wouldn’t seem likely as the cause of your problems. Good luck; let us know what you find.
