"Can you imagine your iPhone 7 plus without vibrator? There are a number of times when you have to keep the ring volume off and turn on the vibrator. It assures you don’t miss out on the notifications and the incoming calls even when the audio tunes have been turned off. But what if you land up with a problem with the iPhone vibrator (taptic engine) only? Well, then, you can’t afford to live with a non-functional vibrator for long and you ought to look for a standard replacement part."
