Since there doesn’t appear to be an answer here, I will tell you (and anyone who comes here looking for a solution) what worked for me. If the phone is buzzing like this when you are charging it using the physical charging port it is usually caused by something interfering with the charging port. Simply try blowing into the port to remove any dust or other stuff and try charging again. If that doesn’t work, try using a wireless charger to charge it. If it doesn’t work or if your phone doesn’t support wireless charging, I can’t help you there but from what I saw there might be an “issue with the display” so look that up on Google or something.
