Ive had my phone since mid june 2018 and it started to make this loud bzz sound whenever i get a notification. My ringer isnt on and i cannot turn it down. I dont know what to do besides turn the notifications off in school. Even when I click the home button it makes the noise.
Are you comfortable opening your phone? If so, more than likely the screw or screws holding the taptic feedback (vibrate module) in your phone are loose and need to be tightened. It’s a quick repair.
