Hi J_Mampilly,
Thanks for reaching out in Apple Support Communities. I understand that you're having trouble with the vibration on your iPhone after updating to the most recent iOS version. I can see why you'd reach out about this behavior; I'd like to help. First, I'd suggest verifying that Vibration is enabled in Settings > Accessibility > Touch > Vibration. If it's not enabled, tap to enable the feature and test for vibration.
If vibration is enabled, try these steps next:
- Tap Settings > Sounds & Haptics > disable both "Vibrate on Ring" and "Vibrate on Silent"
- Restart your iPhone: Restart your iPhone, iPad, or iPod touch
- Tap Settings > Sounds & Haptics > enable both "Vibrate on Ring" and "Vibrate on Silent"
- Test for vibration with the Silent switch on and off.
Let me know what you find.
Best Regards.
