iPhone 7 Plus Vibrator Motor (Taptic Engine). If your iPhone 7 Plus is not vibrating properly during phone calls or alarms/notifications, you may have a bad Vibration Motor. This replacement linear oscillating vibrator for the 7 Plus is the part you'll need to swap out to get that fixed.
This part is standard across all iPhone 7 Plus models, but is not backwards compatible or compatible with the 7 Regular. This part will work with the Apple iPhone 7 Plus, iPhone 7 Plus A1661, iPhone 7 Plus A1784 and iPhone 7 Plus A1785 (Japan).
