constant "Bluetooth keeps stopping"

I just started receiving the error "Bluetooth keeps stopping" on my Pixel 3 XL a week ago. It comes and goes seemingly completely at random, sometimes clicking close app will work and other times it will just keep coming back over and over until I restart my phone. It's a huge problem because it takes my wifi and sometimes I think even my mobile data down with it. I've read a bunch of posts and it seems like many people have been having this issue.

I've tried turning off Wi-fi and Bluetooth scanning.

updating Google Play system update.

Clearing cache and storage of Bluetooth.

resetting every bluetooth device I own

Factory Reset

sideloading an OTA image

Flashing a factory image

I'm all out of ideas. The only thing I can come up with is it's a hardware issue, but generally hardware issues I run into are not so sporadic and random. Usually it's either broke, or not broke. It doesn't seem to correlate to how hot the phone gets. I feel like Google broke something with an Android update. I've tried to warranty it through Google but I purchased it new on Ebay and they want the original purchasers name, email and order number. Anyone know of a way around that for Google's warranty?

As a last ditch effort I just flashed the Sep 18th Android 9 factory image, crossing my fingers that for some reason that does something.

My only other idea is google has driver binaries posted for pixel devices. Do these binaries get written over/rolled back when the factory image is flashed? Or are they isolated and not touched when flashing a factory image? Could flashing new driver binaries fix the problem? If so, does anyone have a guide on how to flash the driver binaries, google gives documentation for sideloading the OTA or flashing factory images, but nothing for how to install the driver binaries.

Try flashing the dec/Jan build then lock bootloader then start phone as normal setup then unlock bootloader. There's also some Bluetooth settings in the developer ootions. Also check battery settings for the app maybe try turning off optizmation for it. There's also a setting somewhere that will let you turn off the ble236a scan it's always on mine new pair list. But the drivers are usually flash with the update or ota. I needed to flash those when flashing Dirty Unicorns. Fastboot flash vendor_a vendor.img and same for vendor_b believe the other is the radio img you would need to extract them with 7zip if using Windows.
Mine did this as well but I was using naptime,and servicly to kill and or deep sleep quicker. Which is what made me think of the battery optizmation

Just a precaution, as soon as you start locking and unlocking bootloader you're going to be doing a complete wipe of your device. So backup before hand. You'll also want to do a complete install of the factory image, with the wipe option, before you attempt to lock the bootloader. If you lock the bootloader and you are not 100% stock of something goes wrong you could end up with an expensive paper weight.

The error happened once immediately after a full factory image flash before I had downloaded a single program or changed a single setting, so I don't see how it could be bluetooth settings, battery optimization, wifi/bluetooth scanning, or a rogue app. Oddly enough, since posting this last night I've managed to go 12 hours without an errors after flashing the Sept 2018 factory image. buuuuuuuut now I'm afraid to upgrade to Android 10 again.

Thank you for making sure I understood this. Yeah, I generally factory reset my phone and laptop once a year so I always back everything up before a reset. And yeah, I haven't changed anything from stock on this phone since I've had it, so unlocking and locking the bootloader should never cause any issues. As I told Billy, the Sept 2018 image seems to have fixed the problem, fingers crossed.

Is it probable that upgrading once again to Android 10 will cause the issue to return? The Sept 2018 image must have changed an internal setting or driver that wasn't functioning properly.

I can't tell you for sure, but i would think the latest firmware should work. There have been a number of Bluetooth fixes since the original firmware, which it appears you're on now. That, and lots of security fixes.

Yeah, I mean I would much prefer being on Android 10 and having the latest updates, I normally update as soon as they come out. But, given that I flashed the Jan 2020 image and bluetooth was still broken, and then flashed the Sep 2018 which seems to have fixed it, I'm hesitant to go back to the Jan 2020 updates. Kind of tending towards the if it isn't broken, don't fix it philosophy right now. If I had time to monkey around with my phone all the time I wouldn't mind, but the semester just started and I use my phone for everything at school so I don't really have time for it to be not working. >.< Such an odd issue and odd fix.

What do you have Bluetooth connected to when it happens?
Nothing. It doesn't matter whether anything is connected or not. It literally happened on first boot up of a fresh flashed Jan 2020 factory image, before I had put a single thing on the phone.
Generally I have my Fitbit Versa connected, I got 2 tiles awhile ago, but first troubleshooting thing I did was remove the app and delete those from bluetooth since those were my latest additions to bluetooth. I have backbeat fit headphones I use sometimes, the same with bose soundlink ii headphones, ps4 controllers, a jbl pulse 3, my car radio. But I factory restored all of those items so they weren't trying to connect to my phone, and then flashed the factory image. So I don't see how it has anything to do with an actual bluetooth connection.

Im having this same exact issue. Android 9 was always super smooth. It all started with the Android 10 update. I was having all kinds of Radio related (wifi/bluetooth/data) issues ever since. I noticed sometime in Nov/Dec that google released some kind of radio system app update and things got a little better. But I still have the Bluetooth problem (like today, which prompted me to find this thread) or every once in a while ill lose all data connectivity and have to reboot my phone for everything to come back. I LOVE the dark theme, but this has to be the worst Android update from a stability standpoint ive ever experienced.

Just want you to know it isnt just you. Its something to do with some phones on Android 10

Yeah, I wish this thread held a solution for you. I've searched and searched and tried every solution I've found on google and nothing has worked, and really none of the threads I have found have ever had a concrete solution either, just one or two people going "well I did THIS and it worked", and a bunch of people saying it didn't work for them. I just cannot fathom how a full factory flash back to the very first image would not revert the changes that came with Android 10. That's why I was questioning whether or not a factory flash replaces driver binaries. It's the only way I could see the factory flash to Sept 2018 not fixing our issue. (Other than it really being a hardware issue, but that doesn't seem possible to me.)

Oh wow, you're still having same issues on Android 9??

Im still on Android 10, most recent update. I did do a full factory flash a few weeks ago and it was quite the improvement. But I still do have the Bluetooth/radio issue every once in a while, like yesterday.

I wonder if it's a hardware issue and/or substandard hardware performance that Android 10 made more prevalent? That's something we'll probably never know

I only pointed to hardware as I had a similar issue years ago. The radio connections were slightly loose so it would come and go. I do hope you are able to figure out what is wrong, was not trying to be rude.

Oh no, I didn't think for a second you were being rude. And I appreciate your idea, just with what I'm experiencing with my specific phone it doesn't seem to be a hardware issue.

Strangely enough, the issue has been tapering off as of late, after the factory resets I just continued to use my phone while I wait to figure out if I can get a refund or a warranty replacement, etc. The issue has been occurring with much less frequency since then. Still happens, but not like it was.

Damn, the Bluetooth bug is back again. It was so bad the other day, my phone kept bootlooping for like 20 mins while I was on the road.

I finally just let phone sit for a while and it fixed itself. Man this is completely sporadic.

Yeah, mines been better for like 4 days, and then it just crashed and rebooted by itself earlier today.

has anyone gotten to the bottom of this yet? it seems to be a result of the play store system update being "stuck" on Sept 1st...even if you get it to download to the current version, currently March 1st, after a reboot it will not show the March update has been applied. And should it actually show that the March update has been applies, within a day the phone will reboot and the bluetooth bug will return, strangely the update to the play store system reverts to Sept 1st.

I'm having this issue with my son's phone. I tried unlocking the bootloader and flashing the factory img from April but of course the bug is still there, and after signing in the Play Store system is of course dated Sept 1st

There is no fix. I made an official Android Issue Tracker thread.

https://issuetracker.google.com/issues/151033055

and a Google Pixel Phone Help thread.

https://support.google.com/pixelphone/thread/32828289?hl=en

Google's being ****ty about it. I eventually just bought a new Pixel 4 XL. I needed a functional phone for school and work, and as much as I hate to spend money on another Google product after this mess, they do make the most powerful pure android phones with the best camera. Ebay FTW, $600, never giving them another penny directly.

If you still have warranty, get it warrantied immediately, and don't take no for an answer. I dawdled around thinking it would get fixed and even though I reported that I was having issues with it directly to Google's phone support BEFORE the warranty expired, by the time I called a second time and pushed a manager to see if they could warranty it, my warranty had expired so they told me to go jump in a lake.

to make it worse, Google told me the phone still has an extended warranty but I'm not the original owner and have no way to contact that individual. But you need that person's email address for it to work. So it was purchased but because of this technicality it's null and void. I get the security of it but it's still garbage
