iphone XR alarm doesnt ring as is the sound is muffled and ring qietly when some one call or texts.

Im on my 2nd iphone XR and soon to get a 3rd one.

calls drops

texts gets mix up or doesnt leave my ph undelivered

ringtones and alarm muffled

although i heard them clearly they dont hear me clear.

if im using the ph, i dont hear notifications of texts or calls same if im playing a video..yes the settings and notifications are right.

I have several tickets and still dont know.. does all XR has the same issue???
