Bluetooth issues

I pretty much love this phone. It would be my ideal device if it had double-tap-to-wake. As it is, I could almost learn to live with using the fingerprint scanner (which I avoid using on all of my other phones) to unlock, but I finally encountered a deal breaker.
I have had all kinds of bluetooth issues. I have a lot of connected devices and I've been encountering the following:
Gear S3 constantly disconnects (even when it's really close to the phone)
Fitbit will not sync
Car Stereo Bluetooth profile deleted itself
AirPods break up, have static, or completely cut out
Here's the thing. I went back to my V20 and I don't have any of these issues. The Fitbit always syncs, the AirPods work flawlessly, the Gear S3 NEVER disconnects, and my car stereo has never disconnected. I have to believe it's a bluetooth stack issue. Perhaps the proprietary processor is to blame. But with all of the bluetooth devices I use on a daily basis, I can't live with this.
I really want to keep the phone, but I think I'm going to have to return it. That sucks because there's nothing else really like it on the market for me. But after all of the testing I've done, I can't draw any other conclusion. Maybe a software update might fix it in the future, but I can't take that chance.
I'm sure some of you will chime in and say "I'm not having any of these issues". That's great. I'm fairly certain you don't have the exact same devices/combination I've listed here. The fact is, my currently daily setup does not mesh with this phone. I still have my Mate 8, but I haven't tested this combination of devices with it yet.

I also have a big issue with this phone's Bluetooth. I can't pair it with a 2014 Pajero. Any other phone works perfect when paired with the car but this one cannot even pair. I always get "pairing failed".
I tried every oprtion and pairing application and still no success.
I know mate 9 has bluetooth 4.2 but it should be backward compatible.
Anyone has a solution or similar issue?

I wonder what firmware version your mate is on.
I'm running MHA-L29C432B138 and I have no problems with my Gear S3, nor with my Mazda bluetooth hookup.

Yeap, latest B138 version.
Gear S3 is fine. Only issue is the car connection

B138 here.
Won't connect to my 451 Bosch Highline car radio (they can't even see each other).
Connects fine to my laptops (Win & MacOS), BT speakers and Xiaomi Roidmi.

I am on MHA-L29C567B138
I have the U.S. unlocked model. So, unless there's something specific about the firmware on that model, I don't know what to tell you. I have tested this repeatedly with all of my Bluetooth devices. Nothing works as it should, especially compared to my other phones. It would be interesting to see if I have the same issues on the Europe firmware, but I'm not flashing it to find out.

This bluetooth seems to be issue with this phone, does anyone know if this is something huewei is working on to fix or its an android issue ?

I hate to be the guy that says "mine works blah blah blah" but I've got multiple devices connected through Bluetooth and have yet to have an issue on any of them. 2 Ford vehicles running Android auto, 3 Bluetooth speakers and a set of Bluetooth headphones.
With that said, I wonder if your actual device is faulty. Has anyone with the issues done a factory reset? If so I'd be contacting Huawei support.

I have same issue as describe. My tought is mate 9 do not accept Bluetooth multipoint connection... 2 devices with same profil cannot be connected in same time

I am wondering if the manufacturer is aware of the issue or not but to me it seems more of a Android nogut issue than anything else

I have the same issue. The Mate 9 takes about 3 minutes to pair with my car where my LGV10 automatically did it within seconds. It also does not seem capable of handling being paired with multiple Bluetooth devices at the same time. It has to be disconnected from one and wait to pair with the next one. For cars, I have tried it with both a Tesla and a Jeep GC and the I have the same problem.

It's interesting and frustrating how different people have different experiences.
As you'll see from my sig area, I am on US version, with 183 firmware. Interesting too, I had first tried a V20, and left it because of BT issues. As you are probably expecting to hear given my intro statement, I am not having BT issues. But, I am on different phone and firmware from most posts here.
I've only had my phone a couple weeks. When I received it it was on 138, and the GPS didn't work at all. Was about to box it back up and send back, but then checked, and had the update. After update, it's been great for me so far.
I'm not sure how different the 138 is from my US phone and yours...but a common thread for problems seems to be (based on this thread) is 138.

I am still having trouble with updated AT&T S7

Around late June 2018 my phone was updated to Oreo. I posted this complaining of a slow and sluggish phone with poor battery life. After a full clean flash the phone improved noticeably but still wasn't where I thought it should be. Certain apps still seemed slow to open I continue to have WiFi issues.
About four to six weeks later there was another update. I'm not sure if it was a Samsung update or an AT&T update (security patch maybe?). Once again all aspects of the phone became slow and battery life plummeted. I was back down to eight or nine hours per charge. So, once again, I performed a clean flash of the phone and things got a little better. I was back on par with my initial post-Oreo clean flash and still nowhere near my pre-Oreo performance.
About four or five weeks ago my phone started nagging me to update again. I kept WiFi turned off and continually procrastinated the update for about a week or two. Finally I allowed the update and again I am having major performance issues. Battery life is unacceptable. I get around eight hours per charge. All apps are noticeably slower to open and run slower. My G-Mail app is slow to open and show new correspondence. My navigation app is virtually intolerable. The telephone app takes forever to open. Often it will ring four times and go to voicemail before the caller ID opens to show who is calling. My Swype keyboard sometimes takes two or three seconds to come up also, I forgot to backup my custom dictionary before my last clean flash so I lost all my slang and cuss words.
Here is an interesting and annoying quirk. Bluetooth now fails. I'll get in the car and the phone will automatically sync to my JVC receiver. This still happens without any issues. The issue is that, at random times, the music will just stop playing through the stereo and it will play through the phone's speaker. The bluetooth connection is not broken or interrupted (the devices are still conntected), it just randomly starts sending music to the phone's speaker instead of the car's stereo. The easiest work around I have is to hit the pause button on the car's stereo, wait one or two seconds then un-pause. It may be simple but it is BS. I shouldn't have to do it. It wasn't a problem before and it should not be a problem now. This happens with other bluetooth devices as well such as my headphones (no pause button) and a bluetooth adapter (also no pause button) that is connected to an older home stereo that doesn't have bluetooth.
So here are my questions:
1) How can I know who is responsible for these updates? Is it AT&T? Samsung? Which 'higher power' can I direct complaints to? Honestly it feels like my phone's performance is purposely being compromised in an effort to push me to a new device. If this is the case then I'll purchase a cheap 'Sprawl-Mart' phone. At least I know I'll be buying a cheap, slow and crappy phone for $60 or $70 instead of a $750 'flagship' phone that is only good for 18 months.
2) Is it possible to set my phone to never even look for updates? I look at it this way; if I have to perform a clean flash every time my phone updates then I don't want the updates anymore. Since Oreo, none of the updates seem to provide me with any noticeable benefits.

Just a bump
Just a bump to get me back to the top of the pack. Hoping somebody has some answers for me.
Thanks,

Is Oneplus became flagship to be killed?!

Hi
Idea if flagship killer was very cool to me so I really fall in love with OnePlus. I became part of community and I really want to help OnePlus to became really killer.
Today, after 4 Oneplus phones I am really disappointed, Oneplus became expensive top brand, flagship company. Rolling out Android 10 without serious testing for company's most expensive phone is most selfish and irresponsible move I ever seen. Looks like to me whole company working on Oneplus 7T Pro, and no one cares too much about "old" phone. This morning I was late for my work because alarm did not ring?! I don't know reason, I don't care why, I am user of 800€ phone and I don't expect that.
Wake up Oneplus,
I'm running official GM21AA on my GM1913 for 2 days, no root, just stock phone.
So far I noticed this problems:
- This morning my alarm did not ring?!
- After that disappointing situation I notices mobile data was off, so I have to turn it on manually
- Choppy audio on Bluetooth in my car ( I have to keep screen on for normal reproduction)
- Horizon Light don't work at all
- During Viber video call, video connection shuts down every few minutes, so I have to turn off then on video call constantly.
- Battery life was very nice first day, but second became terrible. Btw I have no issue with Viber, alarm clock, mobile data and Car Bluetooth during first day of using Android 10.
Any suggestions beside rolling back on Android P or selling and leaving OnePlus and back to Pixel phone

Why not do some research? There are a dozen things you can try to fix your issues. I updated from Stable 9 to 10 using Oxygen Updater and I have none of the issues you have so what is the difference? Maybe you have one or more apps that are not playing well with 10? Maybe you need to uninstall them and reinstall them so that they work better with 10? Maybe you need to do a factory reset (yes it is a pain) and DO NOT let your apps automatically reinstall from Google, to see if that fixes your issues? Or you could just sell the phone and go back to a Pixel! Then when you have the same types of issues with your Pixel you can complain on their forums about bugs and issues that you are not willing to try and fix. Solved!

NO. Still doesn't have wireless charging (which I miss A LOT) and the camera software is still not good.

Any fix for Bluetooth connection issues on Android 10?

Ever since Android 10 hit my device using my Galaxy watch and some headphones has been a pain. My watch disconnects constantly and my headphones do too but not as often. Using my watch is also painful, even while connected certain things won't reach it so i end up missing notifications even though the watch never really disconnects.
Is there anything i can do? I don't want to wipe my device to downgrade just so i can use basic functions of what my phone should be able to do. Would rather not settle with Android 9 so that my Bluetooth works.

Bump

No issues with my watch or headphones, both Bluetooth. However I did have issues with audio consistency on my car and found that resetting my head unit mostly fixed my problem. Maybe doing a reset on your watch may help. Headphones I'm not sure.

Switch back to ?

Yeah reset my watch a million times. It's not the watch. I was running other phones off and on and only the 7 pro does this...

bump again still

I, too, face audio connectivity issues on my OP7P after the Android 10 upgrade on OOS. I paired my OnePlus bullets 2 to my Nexus 6 running AICP pie and didn't experience any connectivity issues. I also have it paired with an aftermarket head unit in my car and that doesn't have any connectivity issues. I've cleared the storage data for Bluetooth and reset networks through the system menu. To no avail. I'm highly annoyed with something so trivial that got past OnePlus Android devs. The connectivity issues happen in a cycle. Upon 1st connection, it'll happen within 5-10mins. After that, it happens every 15-20mins. It sounds like interference or the data being sent from the phone to the bullets2 isn't complete/is corrupted. The audio gets chopped up like when you have poor cell signal on a phone call.

Bluetooth signal worsened after Android 12 update

I usually always laughed at my friend, because his iPhone 12 would make the music go choppy on the Bluetooth speakers whenever he went to the bathroom at the office only just next door, while my awesome OnePlus could play even if I was in another room in another floor, it didn't even matter how far away i was, the signal still went through and amazed us all.
But gosh darn it, after the android 12 update.. even if my phone is just in my pocket - if i point it away from the speakers, the music gets Choppy.. it's an obvious massive downgrade from the signal strength i had before and I was wondering if anyone else has noticed this since updading?

Did you do a factory reset? This maybe needed.
Did you at least do a network reset?
Many Samsung users rolled back to 11 from 12 so it's not just OP devices.
Personally I refuse to go beyond Android 10 with 9 being my preferred OS. This has more to do with resource sucking scoped storage though. Anything from 9 up is relatively secure. 12 especially is too secure

Ugh, factory resetting is such a hassle
I mean if it fixes it I guess I'll have to do it, but I'd hoped it was as a last resort. I haven't tried a network reset, I don't think I've ever even done that before, so I'll just look into how that's done first and try that out

A network reset sadly didn't work, on the bright side my speakers finally plays Christmas music the way its intended - not playing

One reason I don't upgrade especially if the current platform is fast, stable and fulfilling its mission. Little to gain and a lot to lose.
A network reset is pretty painless just need to reinitalize the bt devices and wifi ones if you use them. I'll use it from time to time if having connection issues.
If you can clear the system cache on that device do so. That can fix a lot of bizarre behavior issues especially if you made major software or firmware changes. Many times a factory reset is the best option if you did a major OTA firmware upgrade. Last thing you want is a boot loop; take any sign of system instability seriously. Make sure all critical data is fully and redundantly backed up as it should always be.
Play with it. A rollback to 11 may be possible as well; not sure about that variant.

This has nothing to do with old files requiring a factory reset. Something has definitely changed in the firmware for OxygenOS 12. I now can't be more than 4 meters apart from my device without the audio getting choppy - it's crazy.

Of course I did. This has _nothing_ to do with storage or stale data. It's something they changed in the firmware when moving from Android 11 to 12.

Well a rollback is your only option then or wait until it's patched unless you can track it down. A lot of Samsung users rolled back from 12 to 11 because of issues.
This an example of one of reasons why I never update firmware that's fast, stable and fulfilling its mission. Zero trust in Gookill. They can and have screwed up good products in the past; it's their nature.

ARGH I've been using pixelexperience for months now since I posted this thread, but there were just so many small annoyances so I decided to come back to stock. I had briefly forgotten about all these friggen BT issues so I just installed the newest version again. ARGH XD
Yeah the BT thing is just really annoying.

Same here since Update to Android 12. The Bluetooth Range thing and den slower charging speed (tested with the Android app "Ampere") was very annoying.
None of the known solutions work. The only thing I could do now was go back to Android 11.
Back the Android 11 and bluetooth Range and charging speed ist fine again. Maybe a custom Rom like Lineage 20 or pixel experinece 13 works but in dont want to try, because the installation and the subsequent change back to stock is very time-consuming.
Did somebody test the Android 13 custom roms in view of the two problems??
Greetings

I tried Pixel Experience 12 & 13 on my Nord.
It feels alright most of the time but there's the occasional annoyances. For instance :
- When rebooting my Nord, the system will ignore the current alert slider position (e.g. I'll shutdown my phone on "silent", move the slider to "ring" when the phone is off, and the phone will stay in "silent" when booting up while the slider is in the "ring" position.
- There's no clear visual feedback as to what mode you're in when moving the alert slider (e.g. the little bubble appearing momentarily on the right side of the screen)
- The camera feels janky for some reason. I did not research this area further unfortunately.
- Sometimes, my Nord will not be able to transfer files to my computer, unless I enable "USB Debugging", which is awful.
I did not notice any unusual behavior regarding charging, but those issues are what you get when only one or two people are working on supporting your device rather than its manufacturer.

How about the Bluetooth Problem in Pixel experience 13?

I feel like it's a mix between OOS 11 and 12. It's not as bad; but still not great. I don't have any detailed test results, sorry.
Though keep in mind that I'm talking from memory as I had rolled back to OOS 11.

OK, np... I'll stay at Android 11. I dont understand why oneplus dont fixed that Problem. In the oneplus Community Forum many Users Report that Problem..
It feels Like "you are unhappy with your Phone, buy a new one"....
Next Phone no more oneplus.
