[FIX]How to fix bluetooth absolute volume problem on 7.0 - Moto G4 Plus Guides, News, & Discussion

Problem: For a few days my Bluetooth headset hasn't been with BAV(the buttons on the headset didn't control the phone volume).
Solution: Powering off the bluetooth headset completely through plugging in the charger(if yours support that). Then go into blueooth settings>forget device>turn off bt>power on the bt headset in pairing mode>turn on bt on the phone>pair them. This solved my issue and may solve your too although not guaranteed.
Devices:
- Moto G4 Plus XT1642 with android 7.0 and elemenalX 1.04 and root
- Sony Bluetooth Headset 60 (SBH)

if anyone is wondering this DOES NOT work for the s7 edge on verizon

Google is the one to blame! Nougat release is totally broke bluetooth absolute volume.

This worked for me.
Device : OnePlus 5 - OxygenOS Open Beta 7 Android 8.1 and Motorola Verve Rider+

So, I've found a way to get BT absolute volume work on Nougat
Actually BAV activates when BT device is connecting, but for some reason gets deactivated after few seconds.
So, I've found a way to get BT absolute volume work on Nougat:
Each time you connect your device, quickly press volume buttons on your bluetooth device (headphones, or speakers, or your car) until you see a VOLUME SLIDER on your phone, then IMMEDIATELY touch it and MOVE. It should keep BAV active.
Method is valid for my Xperia Z5 Compact and JBL Charge 2+. If this works for you, please share your success story.

BT Headset disconnects

Hi all!
Here is my problem (tried with several other headsets as well):
When the headset is connected to the phone and you take it from larger distance than it's disconnects of course. BUT when you take it back it doesn't want to reconnect automatically. It's really annoying thing, because i'm using a stereo headset to listen music, and i can't bring it with me everytime when i have to move from my desk. I've had some other HTC before but never experienced this untill now on Raphael.
Any idea how to force TP to try to reconnect as the other devices do?

is this a new BT headset you're using now? I believe some bt headsets simply don't (re)establish connection by themselves
There is a new Bluetooth stack in the Raphael compared to older HTC devices, so this could be an issue with it. Have you tried pressing your headset's play/pause button when you come back in range?

Motorola H3 headset: if i press the call button that the connection is reestablish
IQUA BHS-701-S: i have to turn it off than on to make the headset recconnect
btw: i've also noticed, if no device connected on BT, than raphael simple turns off the BT after a while
Mine has never turned BT off on its own. There must be an option for it, perhaps in power saving.

Bluetooth connection problem with sony Bluetooth headphone DR-BT50

Hi to all
Before I had nokia n97 and a sony DR-BT50 Bluetooth headphone which could connect to n97 and my laptop so easy.
after I buy samsung galaxy s I tried to connect the headphone but no way. the phone can not discover the bluetooth headphone
Before i was on Eclair and try it but could not, after I update to Froyo I had hope to make it work but the problem persists.
here are the bluetooth headphone specifications:
Bluetooth® Technology : Bluetooth Version 2.0
Diaphragm : PET
Function : A2DP, AVRCP, HFP (1.0), HSP (Ver. 1.1, Vol. 2, Part K:6)
Interface : A2DP, AVRCP, HFP, HSP
I was wondering if this is a hardware matter or could connect phone to Bt headset by applying some update.
Anyone have any idea?
Hello! I have dr-bt50 and shw-m110s (korean galaxy). Before froyo i was able to pair devices and translate media to headset. No luck with voice calls though. After froyo pairing is successful too. But when i turn headset off, android forgets about a2dp profile associated with dr-bt50. So i have to unpair device, then pair it again EVERY TIME i want to listen to music or watch a video using headset. This is really sick.

I have a MW600 with SGS I9000, I never had any problems (Eclair included).
I'm currently on Froyo 2.2.1 XWJS5. But I have installed all leaked ROMs with no issues too.
I hope to help you.

Hi, MW600 works well on my SGS since Éclair. Are you pairing it correctly?
here are the instructions from the user guide:
Pairing the headset with another device
1)Make sure the headset is turned off.
2)Turn on the Bluetooth function in the other device
3)Place the other device within 20 cm (8 inches) of the headset.
4)Press and hold down the power on the headset for about 5 seconds until the pairing indicator appears on the display.
5)In the other device: Search for and add a new device.
6)If a passcode is required, enter 0000.
To reset your MW600
1)Make sure the headset is turned off.
2)Press and hold down the power until the pairing indication appears.
3)Simultaneously press and hold down power & call until the headset turns off.

Yes, all of the buttons and touch sensitive volume works. Did you try to reset the MW600?
MW600 can pair with 3 devices, maybe during the time that you tested it, your SGS was set as the "calling device" coz usually the first one if it is a phone or mp3 player will be set as the "music source".
You can either reset or manually set your SGS as the "music source" by long pressing the play button and selecting your SGS.

Thx
Problem solved by uninstalling 3trd party music player, must using the default player...
Oh yeah, is it safe to charge with the galaxy s charger ?
Sent from my GT-I9000 using XDA App
You don't have to reset the MW600 just to pair with another devise, you just need to power off and long press the power, I posted this, 3 posts above.
I tested this with PowerAMP music player and all the controls work.
I've charged mine using SGS charger and USB but I can't say if it's safe, I'm no expert in that.
I Swyped this on my Galaxy S
It seems that the headset sony DR-BT50 is working on XWJS5 rom but not working on the others such as JVP/JVQ, anyone knows which files are involved for bluetooth so port them from JS5 to JVQ ?

Unable to Pair HTC Inspire with Bluetooth Device

Hi
I recently rooted my Inspire and I'm unable to pair my Bluetooth (Plantronics Explorer 210) with My Phone..don't even 'see' the device after 'Scan for Devices'..
I have an old Nokia set and the same Bluetooth is 'pairing properly ' with that ! So,the problem seems to be with teh new 'Inspire'--don't know what
My HTC Inspire Software details are:
Android version 2.3.3
HTC Sense Version 2.1
Baseband Version
12.56.60.25p_26.10.04.03_M

Do I need to Flash another Radio/ROM?
Thanks in advance for your Help....
Did you put the bluetooth in pairing mode? Guessing you did but just making sure. That process is overlooked so many times.
Hi
I don't think this so..as the same Bluetooth works with another NOKIA set !

Strangely,..my HTC pairs properly with my Laptop !
The Bluetooth device too pairs with another Nokio Mobile...But the Blutooth device is not even Detected by HTC Inspire
Does this input give any input to solve this issue?

i have no problems with a number of devices i have tested now.
i have several phones that i have tested pairing with
my car
pulled the blueant out of a box and tested that

couple of laptops
all paired fine with bluetooth

Hi Pirateghost
I'm trying to Pair my 'Bluetooth Headset (Plantronics Explorer 210)' with the HTC Inspire ..This device is not even detected by HTC when I do the 'scan for devices' from the Phone...but,I see the Bluetooth symbol dispalyed onteh phone...
Also this Bluetooth Headset is properly 'pairing' with my another Nokia Phone...
Further my HTC also 'pairs' properly with my Laptop'...
But the HTC doesn't detect the 'Bluetooth Planatronics' Headset!
it's Plantronics Explorer 210 Bluetooth Headset
....But this headset pairs properly with my 'Old Nokia phone'..but refuses to pair with the new HTC Inspire
But,the HTC Inspire pairs properly with my 'Laptop computer'...I'm reallyconfused..what's wrong...Appreciate your thoughts on this
I asked you earlier if you put the bluetooth in pairing mode before trying to pair with it? Not the same thing as pairing your phone to a laptop or using it with a phone that it is already paired to. First time you turn on bluetooth it goes in auto pairing till it is paired with a device. After it is paired with a device you must do something special to get it paired again with a new device. Again I only bring this point back up because this sounds like the only reason your phone cannot see the bluetooth.
How to Pair Your Headset if it Has Been Previously Paired
With Another Device
1 Turn the headset off.
Press and hold the call control button until the indicator turns red
and then turns off.
2 Turn the headset on.
Press and hold the call control button until the indicator light
continues to flash red and blue. The headset is now in pairing mode.
3 Use the commands on your phone to locate your headset.
For most phones, select Settings/Tools > Connections > Bluetooth
> Search > 2XXPlantronics. See your phone’s user guide for more
information.
4 When prompted for the passkey, enter 0000.
Pairing is successful when the indicator on your headset flashes
blue. Your headset is now connected and ready to use.

Thanks Agoattamer ---I totally overlooked it--Perhaps did not have the old Planatronics manual----and after getting into 'pairing mode'--everything is perfect..

Hi Pirateghost
I think,I had been too 'stupid' to overlook this 'pairing step'....and now the HTC is able to connect---Thanks a lot for your time......
Appreciate your help too...for giving such a good 'ROM'

some Bluetooth drawbacks

So I got the honor 8 as my new phone since I wasn't satisfied with my previous LG V10's battery live and didn't wanted to spend 600+ € again.
Two drawbacks I found on my H8 after setting everything up are related to the device's Bluetooth:
1 - although introduced in android 6.0.1 again, the H8 is not able to control Bluetooth volume correctly. I can only control the device's media volume and have to manually set the volume on my Bluetooth device, too. Expected behaviour is to control Bluetooth volume on the phone (this works perfectly on my Xperia Z3 Compact)
2 - you simply can't have to hands free devices connected at the same time over Bluetooth. In my car I have a build in hands free in my car's audio system and I'm using TomTom 620 for navigation and to display incoming calls or initiate calls. This worked perfectly on the LG V10 where all connected devices would ring at the same time and the one I used to answer the call would than do the audio while TomTom would display active call information. Unfortunately LG seams to use a more advance Bluetooth hardware as this also doesn't work on my Xperia Z3 Compact simultaneously, nor on my brand new H8.
What's your experience with that?
For the bluetooth headphone issue, you can head into developer settings and enable "Disable absolute volume" to go back to the old way Bluetooth headphones used to work!

xiaomi 10 lite connected with BT to car entertainment system, only noise during calls

very strange thing.
skoda car, i've used for 2 week without any problems the call when connected via BT to the car system.
but now every call i make or receive, both I and the responder/speaker, hear only a big noise.
Tried with another smartphone and no issue, but very strange if i connect the xiaomi to a BT ears no problems at all, if i connect the xiaomi to a BT speaker no problems at all...
I have already tried,:
-delete and reconnect the phone to the car
-reboot the phone
-manage the bt option on the phone, disable AAC and absolute volume
I have to try the xiaomi with another car....
any suggestion?
android auto isn't connected but it's possible that interfere with something else?
Many thanks

Hello. Any updates on the topic?
Let me add my story here too. The thing is- my phone is mi note 10 lite.
Here it goes. So, recently, about a week or 2 ago the Bluetooth audio stopped working completely on my device. I don't understand where to look, and how did it happen. The phone was global official rom, locked bootloader no root etc.
The situation is as follows : the headphones /car audio system can connect and pair. But there's no sound when you press the play button. Moreover, the Bluetooth works, at least I think it works also because I have a huawei watch connected to the phone. And I have notifications everything is fine.
So during these 2 weeks I tried to clear cache/bt and wifi settings (no need to tell you that my headphones connect and play music with no problems with other devices. Tried on my wife's p20 pro.) i tried to make factory reset. No results. Today I even rolled back on android 11 rom from 2021. Offcical rom. Sadly nothing changed. Everything works perfectly, except Bluetooth audio.
Have redmi buds 4 pro and amazfit powerbuds. With my phone they connect but no audio. With huawei p20 pro they connect and work how they should. Also they have no problems with my mi tab 5.
Don't know what to do.
