Why my vibrator is not working

@kittumawa if the rest of your phone still works like it is supposed to, you want to go ahead and check to make sure that vibrate is turned on. Check something like this video to check your settings. After that I would try a hard reset. But first you have to make sure that you have all of your passwords/passcodes/contact list and backed up your files (pictures etc.) since those will get lost during a hard reset. Here is the How-to for the hard reset.

If none of this works, you need to consider replacing the vibrator. Use something like this video (~2:25min) to work on your Realme

While you work on your phone, take lots of pictures. Once you are done with it, take those pictures and create a guide for iFixit. That will help the next person that has the same problem as you do. It's easy and fun to create these guides. https://ifixit.com/Guide/new The iFixit community will appreciate this.
