iPhone XR call volumen is low

More and more users are reporting this problem on different iPhone models. I believe I have tried all of the suggestions that have been made in the responses to these low volume reports. I have to use the speaker to hear most phone conversations. I have reported this issue on the Apple feedback page. It would be helpful if you reported the problem there as well.

I started encountering same issue with my iPhone 11. I have tried restore setting but of no use. I looks like a hardware failure. This happened to my iPhone 6 few years ago and Apple replaced the front screen then without telling the real cause. I don't want to believe it is a hardware failure, my iPhone 11 is 10 month old.

Please report to Apple here.
