1. Go to Settings
Apple’s “Taptic Engine” uses vibration-based haptic feedback that feels much like pressing physical buttons when pressing an iPhone 7. You can customize this experience in Settings by accessing Home Button & Vibration option.
Your iPhone vibrates depending on the vibration pattern you select; either only when receiving calls and texts or every time notifications arrive. Or if you would rather remain unaware when calls or texts arrive on your iPhone. If necessary, vibrate can even be disabled altogether if that would better suit your preferences.
Erroneous settings are usually behind an iPhone not vibrating when receiving calls or text messages, especially if your phone is set to Silent mode. Make sure the Do Not Disturb slider is set to “Off,” otherwise try rebooting your iPhone to see if that helps resolve this issue.
2. Select General
An iPhone offers many different ways to use its power, from home improvement techniques like using it as a level to alert options such as flashing your screen whenever a text or call comes through to makeing Do Not Disturb mode vibrate if set correctly.
Customizable vibrations for various contacts will allow you to identify it as Aunt Greta calling about her Pomeranian and not some telemarketer, while general settings allow easier access to features through button shapes and On/Off labels. And if your iPhone doesn’t vibrate when receiving calls or texts, the solution could lie as simply as replacing its vibrator motor; though that repair job should be left to professionals.
