Brand new R13 has terrible bluetooth performance. LG Infinim headphones will not connect. Sometimes they will connect but sound still will not transmit to headphones. I will routinely add and remove the headphones under bluetooth devices to reset still will not transmit sound consistently if at all.

There are bunch of logs from bluetoothd saying "Device or resource busy". Not a known issue, we probably can ask test team to try if it's reproducible on our side.
