Voice cutting out during FaceTime video calls on IPhone 11 Pro
On video calls through any app, be it FaceTime or Whatsapp or even Facebook messenger, my voice keeps cutting out. It has become really annoying as the people I am talking to keep complaining that I keep cutting in and out. This happens on WiFi or on cellular data and with any contact. I have already got my phone replaced once and then set it up as a new phone, but still same issue is seen again. Also tried to factory reset my phone and start it without any backup 3 times after (thinking maybe it's some app that is causing this problem), but still the issue remains. I am on iOS14 and on T-mobile network. This problem has been occurring since quite some months now. Maybe this started in some previous versions of IOS and has continued? When went to store for apple support, they claim there is no problem on hardware side. Can an apple developer please investigate this? It is very frustrating to have any video calls like this.
