Bluetooth keeps stopping

Tretiak

Just recently within the last 1-2 days, I've been getting prompts on my GrapheneOS phone telling me Bluetooth keeps stopping. I use it as a Wi-Fi hotspot fairly frequently but this has only started happening out of the blue. I don't have any physical damage to the phone. No drops. Water damage. Etc. I can't seem to find any support for this problem anywhere either, there doesn't seem to be a fix or any explanation for why it happens. I've not downloaded any third party app's recently that I haven't been using for awhile. Here is the error below:

Tretiak Have you tried rebooting?

Have you tried resetting Bluetooth and Wi-Fi settings? That may be somewhat disruptive, but it might be the next step...

Tretiak

Several times. It doesn't work. And if I try to turn on a hotspot it simply says:

Wi-Fi hotspot
Error

Even after I reboot the phone, I immediately get a pop-up that says, "Bluetooth keeps stopping." It doesn't always happen every single time. Even if I let the phone sit for an hour, two hours, three hours while it's off and turn it back on, I get the same prompt. Sometimes I'll reboot and magically nothing pop's up and I can use the device just fine. Then say after a few hours, it'll pop up again and say:

Bluetooth keeps stopping
App info
Close app
Show details

No luck finding any resolution to this. This also never happened once until the most recent GrapheneOS update. Don't know how that may factor into things.

Tretiak Unfortunately, these symptoms seem consistent with a hardware problem. Also unfortunately, the measures to determine whether that is true are probably disruptive, e.g.:

Carefully back up all data,
Use the "factory reset" function to wipe all data,
If the problem persists, flash the device back to Google's stock OS,
If the problem still persists, it is very likely to be due to a hardware failure.

Tretiak

Yeah, I don't think its a hardware issue at all...

After doing some research it seems a lot of people are having closely related issues. It seems the Android 15 update bricked some of the basic functionality of Bluetooth. It makes sense seeing as I never once, even remotely had this problem on Android 14.

A write up on the next beta also seems to indicate that at least some of these Bluetooth issues are being resolved. But it doesn't at all seem like this is an isolated incident.
