iPhone XR ringer volume issue
For the past 4 months I have been unable to keep my ringer volume up. Even after I raise it to its highest level, it drops down on its own and I do not hear it ring. I have consistently updated the software (IOS 14.2 is the latest I have) , and it did not work in previous updates. At the same time the ringer volume issue happened to my wife's phone (XR) as well. Any suggestions why this would happen and how to fix this problem?
Thank you
