Vibrate does not work after changing battery
I ordered a replacement battery from ifixit and changed the battery following the instructions provided on the website. After changing the battery the phone no longer vibrates? I have reseated the connector for the taptic engine but still no vibration. Is there anything else I can try to fix the problem?
Is this a good question?
Does it vibrate at all? Like when you toggle the ringer switch? If I had to guess, I'd say you might've killed the taptic engine.
