I was wondering if other have experienced the same as me? (I have sent my Samsung Galaxy S20+ to repair.)
In the start I occasionally experienced when talking to other people that I suddenly could not hear them/they could not hear me – and I when lost the connection. Of course, it can happen – but it was way more frequent than my old Huawei Mate 10 Pro.
I also occasionally experienced that I lost connection to the internet (Not WIFI – I was using the mobile broadband). I have 2 Sim Cards in my phone – they would show no connection - when shortly after they will show connection.
One time I was sitting in a car (which was not moving).
First both sim cards – showed no connection:
2 seconds later only one of them showed no connection:
and 2 seconds later both sim cards showed connection:
As you can see at the last image - there are full bars for both sim cards. All 3 images are taken from the same place with only a few seconds interval. I have of course tried to reinsert the sim cards and also hard booted the phone.
