FP5 pretends that BT audio device is connected

Sometimes, my device pretends that a bluetooth device is connected when it isn’t, preventing me playing audio.

Recently, I happened to see this video from LTT, which corroborated this. Has anyone else experienced this, and have you ascertained a workaround, if so? I ask because I didn’t notice this listed in ✏ Known reproducible and reported issues of the Fairphone 5.

Hopefully it’s been remediated in android14, but I’ve solely been using that version for a day, so I can’t tell yet.

Can you elaborate? What kind of device(s)? I use different Bluetooth devices and I haven’t encountered a FP5 issue on them. Also no ghost connected devices. Is there a way for you to reproduce it? Did you already report it to FP support? What was their reply?

@UPPERCASE:

1 x SONY WH-1000XM5.

I don’t know. It hasn’t happened for about a week, so I forget what occurred beforehand. It might be after playing music via Spotify with the headphones connected.

Not yet. I shall when it occurs again, because I’ll have enough information for it to be actionable then.

I too never had this problem (FP5 i have 10month), using different earbuds (JLab, Lenovo, MPow), speakers (Wavemaster, EnergySistem), carradio (Dasaita)…

I use YouTube Music and VLC. Just leaving it here so we can maybe find a common denominator for this issue. And I use the Fairbuds XL and sometimes Jabra Elite t75 earbuds. Sometimes someone connects her Airpods to my Fairphone as well. No issues.

Thanks for the information. My brother also uses the Fairbuds XL and YouTube, and hasn’t experienced it.

Perhaps

refers to this. I hope not, since it’s evidently not remediated.

You link to something from 2020 concerning the FP3?

So I’m not sure I really get what happens: the BT device isnt comnected any longer, however its still seen as connected device and Spotify is playing and you dont hear it on the FP?

I think I have seen this with Spotify 2 or 3 times . so really nothing reproducible so nothing I pay much attention to. I dont think I had to reboot the phone when it happened

@yvmuell, no BT devices need to be considered connected for this to occur. Specifically, “Connected devices” can be empty, yet the volume slider irrespective displays the Bluetooth logo.

If I connect a Bluetooth device, it plays audio. However, disconnecting it does not change which audio stream is played.

It’s probably incorrectly not switching between the appropriate constituents of Atribut audio  |  Android Open Source Project.

Yeah now that you explain I remember better how it was. So I have seen this 2 or 3 times probably always in connection with Spotify I think, dont remember which BT device was connected before. At the end without logs or anything to trigger and reproduce rather difficult. So if this always happens to you get in contact with Fairphone

I hadn’t considered getting a logcat output. Thanks.

10 posts were split to a new topic: A14 BT connection issues

Submitted at https://support.fairphone.com/hc/en-us/requests/1205063.

I would not call a report to support as solution…

Btw did you upgrade in the meantime to A14?

Its still ocurring with A14 just had it, even disabling BT doesn t help… Will change the title and if you hevant yet, updating will be the first thing support asks you to do.

Newly connecting a device and disabling BT while connected doesnt help either…

I agree, although I’m very used to having a dedicated bug tracker when I have a problem, so learning how support tickets work (etc) is a little new for me. Usually, posting a GitHub issue to a Discourse thread would be considered the solution because it would publicly track triage of the bug.

If I could add you to that ticket, I would, but ZenDesk doesn’t provide that functionality (especially to a mere user).

The fact that https://issuetracker.fairphone.org/ was removed when @Fairphone transferred to https://fairphone.com/ remains terrible. They could open https://gitlab.fairphone.com/ to us if they so desired…

@yvmuell, yes. I updated immediately - when it was first provided to me, that is. Notably, it hasn’t occurred since, but because I don’t yet know the cause of the bug, I can’t ascertain whether the update remediated it. Unfortunately, I expect that Support shall consider it sufficient.

I already reported it when it happend today and just linked to this topic.

@yvmuell, likewise. Thanks for that.

I use FP5, Android 14 (13 previously), WF-1000XM5, WH-1000XM4. I also use Spotify. I generally don’t experience this issue, except when I do not socket my WF-1000XM5 in the case well enough. Because then they stay on. Other than that, I sometime forget to put Bluetooth off on my laptop and it can cause issues since the headphones try to connect to it first and hijack the controls (or vice versa with smartphone). To mitigate this, I suggest to always put radio’s off when you don’t use/need them. At the cost of convenience.

Do note that Spotify can be controlled from smartphone if it is being played elsewhere.

If I do experience your specific issue with regards to the volume, I’ll let you know.

I suggest if you encounter the issue to create a faraday cage to ensure nothing is MITMing (ie. pretending to be your headphones).

To avoid another discussion here about issues to connect a BT device: All what you dedcribe is not related to the issue here. There is no issue to connect or disconnect the device properly nor Spotify being played on a another device.

@JeroenH, indeed, for that’s the scope of this post - more specifically, the inability for the device to register that a BT device is disconnected, even when Bluetooth itself has been disabled. Consequently, although your previous advice would be of use otherwise, this situation is rather too easily demonstrably a bug in the OS itself.

Quite a tall order, although I’m thankful for the advice.
