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

GrapheneOS Pixel 7 Pro, Shockz OpenFit, Bluetooth audio in calls works but the microphone does not always work and sometimes drops put. Have to manually reselect Bluetooth device in the call for the microphone to start working again.
Edit: using 2024030800 I've had the issue occur today after updating but I've been experiencing the issue for over a month now and only just made an account here to try and figure it out.

Galaxy watch6 classic doesn't connect.

If i open my bluetooth screen it seems to keep trying to connect. It cycles rapidly from saved devices to the top (where the connected devices normally show)

Same thing.

p8 Pro running 2024030800.

Religiously use apple airpod pros new and old generations and have never had issues on any release.

I use a 2nd profile as my daily driver and noticed when switching to the Owner profile sometimes get a "Bluetooth has crashed" notification on the Owner. Will try to save logs next time but doesn't happen often.

We've found and fixed an upstream Android 14 QPR2 use-after-free bug with Bluetooth LE audio discovered via our hardware memory tagging support on the Pixel 8 and Pixel 8 Pro. It is likely causing issues on all devices, not only 8th gen, it was just easy to fix it via MTE catching it as it happened. We'll be making a new release later today with our fix. This thread we posted across platforms has more info (note it was posted before we found and resolved the issue):

No problems with my Apple AirPods Pro (2. Gen.) ever (using with Pixel 7 Pro and 8 Pro).
Now with the newest GOS version 2024030800. Works very well.
Thank you for the great work!

Jabra Elite Active 75t earbuds working fine before the update and on the current build (2024030800).
Pixel 7 Pro

BT works fine before and after the recent updates (currently using 20240308) on P7.
Tested with Google Pixel Buds Pro, Mazda car, Toyota car. Connection is established ways faster with the cars.

Thanks a lot for all your efforts!

    "Releases are tested by the developers and are then pushed out via the Alpha channel. The release is then pushed out via the Beta channel shortly afterwards. Finally, the release is then pushed out via the Stable channel after being tested by some users using the Beta channel. In some cases, problems are caught during Beta channel testing and a new release is made via the Beta channel to replace the aborted one."

    Below devices also work pretty well and connect faster than before the update:

    • Jabra Evolve 65
    • Inateck KB01101 (keyboard)

    GrapheneOS I tried this update, and unfortunately it did not fix my bluetooth issue with the said medical device, same error "Connection failed" when it requests pairing (the pairing code does not appear on the phone)

      doffactory Your device likely broke due to the major security improvements for Bluetooth in Android 14 QPR2. It's likely also broken on the stock Pixel OS. The only way it would be broken specifically on GrapheneOS is if there's ANOTHER new memory corruption bug that's being detected. If you have a Pixel 8 or Pixel 8 Pro to test with, that could largely rule out this possibility since MTE would detect it and make a crash report that's easy for us to deal with compared to weird symptoms stemming from something like use-after-free combined with zero-on-free defending against it which can result n the functionality not working due to memory corruption bugs but protects against exploits.

      Galaxy Watch Pro 5 is still not connecting. Will there be another release/fix? Thank you

      GrapheneOS Pixel 7 - Sony XB900N headphones wok perfectly. LDAC works same as before updating. I have not been able to test whether or not the Fast Pair prompt works when pairing for the first time.
