Since the OS update to Andoid 6.0, my Z5 no longer maintains a Bluetooth connection with any of my devices. It connects OK but after a minute the connection drops and then reconnects. It keeps doing constantly.

Any ideas?

I just got some information on the logs you sent me. Can you please try remove the pairing with your car from Settings -> Bluetooth -> [settings icon next to your car] -> Forget and then try to pair them again.

@Javlar

Can you please also try this suggestion? Also see the PM i sent you.

Have tried what you suggested and have even reverted back to factory settings twice and its not worked. I've tried it with a Motorola phone with Androuid 6.0 and there are now issues with that.

I have a similar problem. Bluetooth audio is stuttering to the point where it is unusable. Seems to be related to CPU/device usage, as the issue is much more audiable when doing CPU intensive loads (loading webpages, installing apps etc.).

I have tested with three separate devices (B&W P5 Wireless, ODT Big Turtle shell, Frankenspiel FS-X) and the same issue is present across the board.

Using my Nexus 7 (2013) which is also updated to Marshmallow shows no issues, and this issue was not present before the update to Marshmallow. I have used the P5W for over a year, both with my Xperia Z3 and the Xperia Z5 and the issue has never happened before.

I tried booting into the failsafe mode, and the issue was not very noticeable (however still present). I would be happy to help debugging this if required, otherwise I will be flashing back to 5.1.1 later in the weekend, as this makes the Z5 unusable for commuting.

I tried this earlier, didn't help.

However now I have changed car and phone is working fine with Mercedes-Benz.

There is another thread on bluetooth stuttering

If you do find a fix for this, can you post to me as well. I nearly crashed the ca today trying to make a call because it dropped out at the wrong moment. It does it with all three cars hat I drive. I also have a smartwatch, I wondered if that might be the cause??

Hi Rickard,

why the testing team cannot reproduce a big issue like this? It is very simple... The device after 2-3 days (or less) of uptime will start stuttering when you listen to A2DP audio and you do some basic tasks (like web browsing ,installing an application, etc).

Here are also some logs provided that shows the buffer underruns.
