iPhone 8 charge port, vibration, sound, and volume buttons not working
I have an iPhone 8 that I am trying to repair. The issue is that the charge port doesn’t work, the volume buttons don’t work, there is no vibration whatsoever (I have already checked the settings), and there is no sound. The phone will charge over wireless, however. Even stranger is that when trying to change the volume in control center, the slider is stuck at full volume and does not react to touch.
I was just wondering what part is the culprit. If the taptic engine goes bad, could it cause all this, or could all the malfunctioning parts be damaged and need replacing?
