bell sound rings when I go into setting app
hello, I'm currently using Iphone XS with the latest ios version, and I have a problem that almost 3 times out of 10, when I go into setting app, my phone rings the default bell sound for about 1-2 seconds even when my phone is on silent mode. I have tried iTunes reset and use the phone without backup, but this happened again and I am not sure how to fix. Does anyone knows how to fix or had same problem with me?
iPhone XS, iOS 13
