Maybe it has something to do with this problem: https://talk.sonymobile.com/t5/Xperia-XZ2/Bluetooth-stuttering-issues-with-the-codec-AAC/m-p/1370672#M3548 Just give it a try and manually set the Bluetooth-Audio-Codec to "SBC". Also you can play a bit with the AVCRP-Settings.

Since the Update to Build 52.0.A.3.163 I have some annoying Bluetooth-Issues. Now - at Build 52.0.A.8.14 the problem is still not fixed. As soon as I start my Car (BMW, HiFI Audio System) Bluetooth autmatically connects with my XZ2. After a few seconds i can hear the sound stuttering or the Playback speed varies. Really annoying. I found out that this the problem has to do with the audio codec. After every connect the Codec is auto-set to "AAC". A little workaround is to change the Bluetooth-Audio-Coded zu "SBC" in the Developer Options. But the annoying thing about this workaround is, that you have to repeat this every time you reconnect. I can't manage it to make the SBC-Codec sticky. The following steps I have tried so far * Smartphone Factory Reset (with my pc) * called sony customer care (they dont know anything) * completely reset of the BMW * Tryed all AVRCP-versions in the Dev-settings (1.4 workst best but still stuttering) * connected other Phones to my cars HiFi (no problems there), to exclude prolems with my car's HiFi The Problems are also described here: * https://forum.xda-developers.com/xperia-xz2/help/52-0-3-163-bluetooth-problems-car-t3892571/post78734440# * https://www.motor-talk.de/forum/bluetooth-aussetzer-android-und-aac-t6545334.html (german) * https://talk.sonymobile.com/t5/Xperia-XZ2-Premium/Poor-bluetooth-audio-playback-since-January-52-0-a-3-163-update/td-p/1361652/page/ * https://talk.sonymobile.com/t5/Xperia-XZ3/Bluetooth-AAC-Codec-Buffer-Issue/m-p/1367766#M1527 Does anyone have an idea how I can fix this? Many Xperia devices seem to have this problems..
