BT transfer is working with the new build. I tested BT headphones for quite a long time too and it works fine
BT headphones work just fine, but file transfer is still broken. Now one can send files, but can not receive them - process freezes on 83-87%.
Also, I've encountered device sleep issues. It active all the time (no deep sleep at all) so 40% of battery drain thought the night with WiFi and Data off.
