My iPhone 5 will not vibrate.

Resetting my iphone worked for me.

hello sir i m using iphone 5s late time i have updated IOS . Vibrating don't work i m all settings check not work plz help me

This what fixed my vibrate:

Go to settings , general , accessibility , vibrate and turn it on.

For some reason it went off and that's a way to fix your vibrate

Tried the other stuff but it was the settings reset that worked for me! Thanks!

Thanks, tapping (gentle tap) my phone with hand twice worked for me as well !!🙂

Thanks buddy it really worked for me also. :)
