My galaxy a72 received the one ui 4.0 update and after the update I was not able to use my Bluetooth earbuds with the device. Everything I connect my earbuds the media file in my device does not play. I believe it has something to do with the Bluetooth audio codec as my earbuds use aptx but the new update is showing some error with aptx codec.
