I am using the Xiaomi Mi A2 phone with gear s3 frontier and galaxy buds. My phone has Bluetooth 5.0 version. I use both devices at the same time. When I listen to music my watch disconnects and I am not able to switch song by Gear s3. When galaxy buds stops playing music, my watch connects again. Also, headphones have a poor connection when I put my phone in my pocket. I guess it might be a problem with my phone but maybe 2 devices connection can be fixed by some trick?
