Have you ever faced an issue with mobile Bluetooth? I can connect to any external device with Bluetooth, I can skip songs, rewind everything is working on data level but sound is not transmitting (only sometimes, when I move/push my mobile device in a certain way).

I tried factory reset

I tried safe mode

Nothing, still same

I got Samsung S21 FE 5G

I was wondering if you can help me out to find a way to troubleshoot this, either some guide or at least some analytics app (I’m quite familiar with IT protocols)
