Vibrations

Hey there, devswarup,

Thanks for visiting the Apple Support Communities. I understand you're having some trouble with the vibrations on your iPone, as they sometimes work but other times do not when expected. I'm happy to help!

From hat you've tried, I would suggest toggling the vibration options off, then back on: How to put your iPhone on vibrate, ring or silent mode – Apple Support.

Then, restart your phone: Restart your iPhone - Apple Support and check for any available updates: Update your iPhone, iPad, or iPod touch - Apple Support.

If you still have trouble after that, please get in touch with Apple Support directly: Contact Apple Support.

Best.
