Taptic engine not working - how to test outside of phone.
I got a client's phone today that is not vibrating. It was previously jailbroken, and had the issue a few months after that. Now after damage, no signs of drops, I'm the "first one" in it. (found some finger prints in the speaker)
I'm not sure if it has a bad lightning assembly, taptic engine or something else. I don't have spare parts to test at the moment. Any idea how to test it outside of circuit? Or any pin outs for it? Ideally I'll have another iPhone 6sp come in to try this one in that phone, but I'm not holding my breath.
