  • Request for testing and feedback with Bluetooth on Android 14 QPR2 GrapheneOS

GrapheneOS Since the first QPR2 release I have issues on mx Pixel 7 listening to music. When I listen to music on Spotify, which is running in the workprofile, and turning the screen of, after approximately 5 minutes the audioserver crashes once and then the music is extremely stuttering.
Basically I can only listen to music now, when the screen is turned on

If recommended I can also open a Issue on Github

      Hi, similar to letgamer and emilycestmoi, Bluetooth disconnects while playing music when screen is locked. If on call, there is disconnect and the call is dropped. No such problem is there while the screen remains on. I am using a P7 pro running 2024032100 from Beta channel.

      • Here are the logs for Bluetooth crash when it is simply switched on/a device is connected. This occurs 2-3 mins post screen lock

      Hope this helps in identifying the problem. BTW, big fan of Graphene OS. Thanks a lot for all the effort.

            Like user topro, I too am able to connect to my bluetooth OBDLink (LX model for me) using beta channel build 2024032100. Thanks for doing this!! Hopefully this tagging issue is just a one-off mistake on their part and not part of a new pattern.

            Hi all,
            hm, so this is strange. I still can't get the Pebble Time paired using the Gadgetbridge app though I can still pair it using the system preferences. With latest alpha release, of course.

            BUT using the old, original Pebble app, it now works! 🥳

            I used the Pebble app for initial configuration; but as it didn't work well with GrapheneOS 13 when I set everything up in autumn 2022 I deactivated it (but kept it). Now with current GrapheneOS the app seems to work well again and I'll keep it to the disadvantage of Gadgetbridge. Have to do a longer term test (fingers crossed).

            Now it seems to me the problem is not the watch - but rather the Gadgetbridge app, maybe in conjunction with GrapheneOS?

            I added my comment to their specific issue here: https://codeberg.org/Freeyourgadget/Gadgetbridge/issues/3596

            Cheers

            @GrapheneOS Thank you, yes it was indeed a hardware error. I bought the phone to use GrapheneOS without trying stock Android. Bluetooth is broken on stock Android as well. Phone was returned. Thank you for all your work!

            Bluetooth tests with Pixel 5 on 2024032100 alpha release:

            Garmin watch (2021) syncs fine through bluetooth with garmin connect app = WORKING
            Polar watch (2020) syncs fine through bluetooth with Polar Flow app = WORKING
            Polar bicycle computer (2015) syncs fine through bluetooth with Polar Flow app = WORKING

            All worked fine before & after QPR2 .

            matchboxbananasynergy Yes, broken on stock as well. However, there is another observation.

            This issue occurs only when WLAN adaptor is switched on simultaneously (not with mobile data on or when WLAN is switched off) with Bluetooth. So, probably not purely a hardware issue and probably stems from the HAL.

            However, for anyone else facing the same issue, check if the WIFI is switched off. It works then.

              Hi guys, yesterday the update of 2024032100 landed on my phone. Did not have yet the opportunity to test it with my medical device just yet as I am on a journey.

              However, I am able to report that this version somehow broke the internet sharing between 2 android phones via bluetooth (ie. not WiFi hotspot). Tested between Pixel 7 with GOS and Pixel 5 with LineageOS

                GrapheneOS unstickied the discussion .

                @GrapheneOS Like the OBDLink I can confirm BlueDriver scan tool is working with the 2024032100 release.

                Thanks for all devs' hard work!

                I can also confirm that the Galaxy Watch 5 Pro works like before. Nothing I needed to change on my end. Just installed the Alpha and the watch was back on track.

                Thanks a lot for that!

                Pixel 7 Pro - beta channel 2024032100

                Can confirm this update fixed my issues with OBFLink MX+

                Thank you!

                I can confirm both Watch 6 Classic and my Oppo running AsteroidOS are working properly, battery on the Samsung watch seems to drain a little faster than I expected, its seems to run the watch down faster than Wifi did, but it last me the day so I dont care at this point, good work GOS team.

                4 days later

                Since this does not yet seem to have been reported yet:

                With version 2024032100 on the Pixel 4a (5G) (updated via Beta release channel), the battery percentage of paired Bluetooth headphones is no longer shown (neither in the Bluetooth quick toggle nor in System Settings > Connected Devices).

                Is this the currently expected behavior? And will the battery percentage display return in the next versions?
