All Mate 10 Pro have Crippled Bluetooth

I have noticed this is a widespread issue and I've decided to raise it. This needs to be fixed and Huawei should stop ignoring this problem. The Bluetooth is basically crippled and locked to SBC. I've tested multiple devices and all exhibited this behaviour. Why is it ignored? Are all the reviews fake?

i read that Bluetooth options in pixel dont stick too. so it must be some wierd oreo crap. you cant even change gpu renderer. it always defaults back. best way to handle that is to chat with huawei support and check it out.

I don't use Bluetooth very much but it appears to be the same for the regular Mate 10 as well. I'm currently using my virtual desktop so I could not test if after changing the setting in developer mode does it stick after a reboot?

this confusion is due to a lack of follow-through. all oreo devices have this "issue". it's not an issue at all. if a connected bluetooth device supports these codecs, the best one will automatically be selected. it is not limited to huawei devices. this is normal and does not affect functionality. you should take down this thread so no one throws any fits for no reason.

Well mine switches to aptX automatically when I connect to aptX-compatible devices. However you are correct that I cannot manually change it in developer settings.

Further testing has shown this issue not to be an issue, I've managed to successfully connect to an APTX device and the codec was selected. Video removed. Apologies for this confusion.

Doesn't matter, it will still randomly switch to loudspeaker and the quality will still be terrible.

I don't have any issues regarding Bluetooth for now, haven't really tested aptx I think, but it worked fine otherwise. And never switched to loudspeaker or so

It's not crippled, it's buggy.
SBC and aptX have high noise floor and specially on SBC, it causes some deformations to the Audio.
AAC is totally broken.

Good for you, people here all have Bluetooth problems:
https://www.android-hilfe.de/forum/...oth-problem.853624-page-19.html#post-10970173

I have no issues with my Bluetooth headphones, the Sony WH-1000NX2
The highest quality of transmission is selected automatically, LDAC, that's 990 kbit/s
It's the best Bluetooth can do in the Audio section.
The Sony headphone App confirms the LDAC connection

i am trying my friend's MDR 1000x. i tried both SBC and LDAC. Now I can't go back to LDAC. Help please

Aac not working on p20 pro, works fine on the pixel 2

Bull****.
AAC No longer works on my head unit and my Bose QC35 Headphones.
It worked perfectly before 8.0.0.128 update.
Factory Reset does not work, nothing works. It refuses to use anything else than ****ty SBC.

they are reporting issues with many devices on that forum. android has always had some issues with bluetooth. huawei is no exception. my samsung and sony devices were the best by far. i think it's because of improvements that they make to the android system.

Anyone on b142? Can you comment on if the Bluetooth audio quality is better?

Can anyone confirm if b142 solved sbc problem? I think aac is stilo broken, but sbc quality?

Solved.

I don't have a clue what you guys talking about with all those 3 and 4 letter/digit combinations of names but i feel I've gotta share i use Bluetooth all day long for different kinds of profiles and i mean all day long, and to say this doesn't fail nearly as much as nougat did would mean i imply it does fail to a certain, however small, degree, which isn't even close to being the case, so... But i do notice the in band ringing settings don't stick just like they don't stick in my Oreo S5...

I've had Android phones since 2012 and the Huawei mate 10 pro is the only one with Bluetooth issues. Constantly dropping parts of songs when connected to my mazda 6. Infuriating to say the least. The most expensive phone I've ever had....

Aptx codec dont work on Oreo keeps reverting to SBC.

Is Aptx codec enable on Oreo?
Every time I change it it keeps reverting to SBC but my headphones are aptx HD compatible....any ideas?

That's because the Note 8 supports just Aptx and not Aptx HD

Thanks for your reply but not relevant because it should work fine hd or not....
And it's the same whith the Sony codec, none sticks and notice that when you change the codec in the developers zone and then you just start Bluetooth without any device paired it reverts to SBC automatically. Someone is able to change it?

In fact, at least for me, as soon as it connects to a paired device it auto selects the compatible codec.
For my MacBook pro it's AAC, for the Sennheiser Momentum is aptX, for the Bose SoundSport wireless is again AAC.

Did you try Developer Options.
I checked also I don't see BT codec option in the BT settings. Only available from Developer Options.
Edit: for LDAC I do get this option in BT settings so don't need to use Developer Options. Also Note 8 does not support Aptx HD.

I tryed an app call "media codec info" and aptx is not apering in the list so i dont know if is realy activ or not....

Hi, after april update its working good....
Diference in quality sound is huge...thanks to who try to help me !

Do you have anything else connected to your phone via Bluetooth, at the same time? Like a Samsung Gear watch, Plantronics Headset, ...
If the second device is not aptx compatible the phone will stay in sbc on both/all devices.
I had the same problem but it got solved as soon as the Sennheiser Momentum was the only device connected to the phone by Bluetooth.
After disconnecting all other devices, stop then restart bluetooth. It should connect automatically to your headphones on aptx.
Hope this helps.

You can't enable it on a device that doesn't support aptx. if the device supports aptx it will be enabled automatically in developer settings. When you disconnect it will go back to SBC

You have to turn off the "Dual Audio" option in settings... Will work after that

aptx HD

Hi, I understand the P20 Pro hardware supports aptx and aptx HD butdoes this work out of the box or does a codec need to be installed? I can see it in the Bluetooth section of the developer options but I can't select anything but SBC.
Thanks

Does the option only change when connected to a compatible Bluetooth receiver? I thought my car receiver was compatible but if that's the case then I guess not.

I had the same issue with regards to Bluetooth defaulting to SBC, after some reading I discovered that it was possible to change the Bluetooth mode on my headphones by holding a button combination, it went from prefer connection to prefer sound quality and unlocked aptx and LDAC on my Sony MDR-1000X. So the P20 Pro is definitely capable of it without any additional codecs.
Maybe read the manual for your device and see if it also has something like this.

I have this problem too.
On my OnePlus One i can change the audio codec, it should not depend on the bluetooth headphones connected. My Mpow Wolverine sounds way better with the One Plus One, on the P20 pro it sounds like sh*** ;any suggestion?

I have headphones that are both SBC and AAC compatible.
Paired to my pixel, aac works great.
Paired to p20, it sutters, skips and is stuck on SBC

I noticed when there is an actual icon just after the Bluetooth device name of my headphones that says 'APT-X', in the phones Bluetooth settings.... My previous Huawei P9 didn't have it or support it so did surprise me a little as I didn't look into it when switching.

On the P20 you can change the BT codec (in developper settings) but the settings doesn't stay...

Same **** here, guys.
PowerBeats 3 are in AAC with Pixel and S9, but in SBC with my P20 Pro. And I also hate that EQ is not avaliable.
I have emailed Huawei, but those dumb idiots are asking for IMEI and system version... They don't realise, that it's a wide problem....

Contentear Huawei Team, I have purchased my P20 Pro during a first sales week at your store in Singapore. In general, I am happy with it, but, I have COMPLETELY confused with your audio experience. PROBLEM: I own two pairs of headphones: Bose QuietComfort 30 and PowerBeats 3. I don't understand why I am not able to tweak EQ over the bluetooth! S7 was able to do it, old Sony Z2 was able to do it too, but 1000$ phone by Huawei with triple camera and AI can't provide damn equalizer! I don't need any processing by Dolby, I just want to add some bass, because I am lisening to EDM, not a classical music, I don't need a analytical audio presentation. Then, codec selection is broken! PowerBeats are not able to get their native AAC, and Bose are working in SBC mode. What a shame! I can't tweak audio, and I have to listen compressed nonsense. I didn't expect that I will have to deal with such problem in the 1000$ phone. Please, release the software update, I would like to have at least eq.

Thinking of buying some Sony 1000xM2 which are aptx HD compatible but if the sound quality isn't any better, I won't waste my money

My Sony MDR100's use LDAC and sound great. They have a built in EQ profile that kicks in once they are powered on according to reviews. I could of sworn it was using APTX HD at first but I was mistaken.

Ah, I didn't know the P20 Pro supported LDAC.
Just got to wait for my Bose to sell on eBay now

Tried on a few different headphones here. Seems apt-X is working, AAC is not.
110 firmware.

My p20 pro is on order and not arrived yet, but what you should try is:
1. Clear bluetooth connection of remembered device
2. Enable Developer settings, go to settings->about phone->click on 'buid number' a bunch of times (8?? from memory)
3. Go to: Settings->developer settings->the bluetooth sections and select whatever you want to be the normal
4. Re-connect your bluetooth device. If its compatible then it will default to your previous selection.
At least, this is how it works on my S8, Zenphone 3 deluxe and Oneplus 3T, with my Sony WH-1000XM2 and audiotechnica headsetsand WI-1000X.
But they all have custom roms and i have never had a Huawei so im not 100% sure.

In theory the Bose QC 35 ii headphones support both SDC and AAC but I can't select AAC in the developer settings. Are others having the same experience?

Yeah I get the same issue with the bose headphones but ldac works when I connected to a sony speaker

Im in the process of buying some earphones that supportthe newer aptx low latency codec as I will be using them for gaming aswell. We know p20 pro supports aptx and aptx HD but does it support aptX LL

Yeah just received my Anker SoundBuds Curve headphones and it shows aptX next to the connection in the bluetooth settings. I guess AAC isn't supported as it's not listed on Huawei's tech specs page- https://consumer.huawei.com/uk/phones/m/p20-pro/tech-specs/ I also don't see aptX LL on there so I supposed that's also not supported

I've changed nothing. Only installed .128 Firmware with funky Huawei. When I connect my Ultrasone Sirius Bluetooth Headset there is automatically a aptx-Icon near the name. Nothing to change in developer-settings. See my picture on instagram:

Change Bluetooth Codec

Hello guys !
I just updated my MIUI ROM from Android 8 to Android 9. Since I have this one, my Bose QC35 II connected via Bluetooth uses the SBC Codec, which delivers a bad quality comparing to AAC. I tried to change this via the developer options, but when I set to AAC it always comes back to SBC. When I was on Android 8, I had the AAC.
Do you know how can I change that ? I'm on MIUI 10.1.1.0 Global
Thanks a lot, hope my english is understandable

I didn't find a solution, always on SBC Codec which the sound quality quite bad. If anyone has a solution

Isn't Aac a iPhone/apple thing....?
Anyways you can force a specific output mode in developers settings.
My mi8 on global beta defaults to aptx when using my Bluetooth headset.

No it isn't, it's a classical codec. I tried to force it, but it always goes back to SBC, here is my problem !

What I meant is that aptx is superior in every way.
But I guess the BT device your using is aimed at iphones and doesn't support aptx ?
Maybe try and switch to global beta and check if the issue was fixed.

Same thing on my mi mix 2s. While everything works just fine with an Nvidia shield and Android pie. So it's xiaomi fault. I'm Very disappointed because SBC is really inferior.

Try developer mode!

Already tried on dev mod, doesn't change anything. When you set on AAC, the phone simply doesn't care, hope it will be corrected in an update !

Now I am having the same problem and couldn't find any solution. In Developer options, my arrangements revert to old ones when close, they don't stick. I have Android 8 MIUI 10 Xiaomi Mi6. Via Magisk Manager, I flashed codecs and necessary modules to my phone but nothing's changed. when i connect my JBL Free to my phone, SBC logo right next to the earphone's name is there. Before I lose my mind, someone please help me! I am inexperienced to this complex Android world :crying:

I'd start by posting in the correct MI6 subforum

You can use PowerAmp, it can force better audio codec (by cable and BT).

Have you tried it ? It doesn't work

Just a quick update, since the last update 10.2.3.0, i've got the AAC when using my Bose QC-35 The sound quality is waaaaayyyy better than before. Thx Xiaomi !

I didn't receive BT fix with my new update and I dont believe I will I bought Sennheiser Momentum True Wireless Earbuds and I rarely have stutters thanks to aptX but if codecs were good I would have perfect connection with these earbuds.

I'm afraid you just have to turn on BT in order to change BT CODEC

Unstable Bluetooth bitrate

I have a serious problem with Bluetooth audio.
I have really good headphones, but they are quite old and there's no support for ldac or aptx (just sbc). However I'm coming from Huawei P20 Pro and I never had any problem with audio quality on that phone.
And what exactly I mean? When I'm listening the music I can hear occasional drops of audio bitrate. It's extremely annoying. And no, I'm not using different Bluetooth devices (but I was able to do this with Huawei which had older Bluetooth version [!]), everything about multiple output is disabled, that option in developer's menu is set to 1.6. I'm out of ideas and pretty disappointed that premium device like Note 9 have problems with basic functions like this.
Ps. It's not a problem with my device. Same thing is happening on my friend's Note 9.

connect headphone via Bluetooth then go to
developer mode enable it/Bluetooth audio codec/(select the code you needed)

At what volume do you listen via bluetooth?
I have the same issue with my car receiver and noticed that if i play it at max volume i experience that and if i play it at a slighty lower volume, one or two steps from max, the issue is gone (or so i hope) for now it seems it is resolved by lowering the volume from max, or it is fixed in CSC1

I'm not listening on max volume, but sometimes it's close (older or more niche music recorded and mastered properly).
Btw just tried listening on my dad's S8+ and it's the same, so Samsung generally has something broken with sbc codec which is rather disappointing.
Btw, I'm using European Exynos model.

That's probably why Samsung still includes the headphone jack with their phones. I don't use bluetooth that often, except in the car and I don't recall experiencing any issues with it. Maybe I don't pay attention to it, but I will this time and see.
