Phone Vibration not working

• ​First, restart your phone.
• ​Go to the Phone Settings and check the vibration intensity and toggle switches (On/Off).
• ​If it still doesn't work, you need to check the vibration motor. This is often caused by a loose connection/cable; the motor itself rarely fails.

Well restart you phone and then check if the issue remain or not if yes the issue remain then check for the software version sometime outdated software version can also be the reason of this kind of issue so make sure that your phone is updated to it latest and stable software version.
