I have an iPhone, since I have updated my phone I’ve had a problem. When I’m on call, Facebook messenger video call or on FaceTime it always cuts out and it’s got nothing to do with my network because it’s completely fine! I have turned my phone off multiple times, ended the call to see if it’s just a glitch and deleted the app (Facebook messenger) incase it’s the app but after multiple tries after trying everything it still doesn’t work. This has started happening after I updated my iPhone a few days ago and I was wondering if it’s because of the new update or because of O2? The new update is called “IOS 13.4.1” Could I have some help please. Thank you
