[Q] Buletooth A2DP skipping! (Gnex)

Both the stock ROM and Android Open Kang Project - maguro build 19 ROM's are skipping a lot when I play music via Bluetooth using a2dp to my car stereo. My other phones Sony Ericson k800, iPhone 3G, and the Samsung Galaxy S Vibrant almost never skipped. My Galaxy Nexus on the other hand is skipping about 12 times per song (2-3min songs). I have disabled WiFi and search for available wireless networks. I have tried a few factory resets, cleared all the cashes, re-flashed, and re-paired the Bluetooth many times. Nothing has improved. For me its a big deal because since 2006 I have been using Bluetooth to listen to music in my car. On a side note when I use the car stereo to take phone calls there is no problem (does not skip) its just the A2DP part of the Bluetooth that has a problem. How can I fix the A2DP skipping issue on my Galaxy Nexus? Should I RMA the phone or is this a common issue for the Galaxy Nexus?

I have the same problem. Using bluetooth for audio, I have very frequent skips. I barely hear anything. Just a short blip and then silence. Sometimes reconnecting helps, but I have basically given up trying. I use the 3.5mm now which is a pain because then i cannot use bluetooth for calls. annoying.
I have asked about this issue and am waiting for an answer.
good luck,
chris
EDIT: I found that maybe? turning off NFC helped. Went out to test and it may have helped. It's 14 degrees now, so I won't be braving that too long. Will test this out tomorrow.
Fingers crossed.

Is the skipping problem only when screen is off or all the time?

all the time.

Did anyone find a working solution to this?
I listen to music on my laptop over A2DP and the skipping is really really annoying!

I will second this problem. Strange that it seems to mostly happen when the phone is placed in a pants pocket. I have tried duplicating the problem by covering the phone, shaking it, bumping it, anything that might be happening to it in the pocket. And, nothing seems to replicate the problem.

I second this problem.
Strange that it is most prevalent when the phone is placed in a pants pocket. I can leave the phone on my desk and was 30 feet away and have no skipping; but place it in my pocket and it skips all over the place.
I have tried to duplicate the problem by covering the phone, shaking it, bumping it. Anything to recreate the pocket environment. But, nothing causes the skipping the same.

Any solutions to this problem found yet?
I'm on a Verizon Samsung Galaxy Nexus and a Motorola S10-HD bluetooth headset. I've been through many ROMS. Was on ICS, and am now on JB 4.1.1. I have the latest 4.0.4 radios. None of this matters. I'm having the same problems with the connection and it's bugging the crap out of me. My bluetooth FM transmitter is fine in the car and my phone calls are fine.
Using the phone, more than 30 feet away in a room: fine. Walking: fine. In the pocket, a couple minutes later and it cuts in and out. The latest ROM I flashed (CNA 3.2.0) made it much better, but it's still crap. I can listen without getting that annoyed now. It used to start cutting out constantly and sometimes I just gave up and stopped listening to music.
Any ideas? Looked at these other XDA forum threads, but there really wasn't a solution there.
Thanks

Pondering:
I think this may be a headset issue more than the phone itself. A lot of these responses are for the Motorola S10-HD, and the like, headsets. I think that it is a coincidence that these newer bluetooth headsets arrived on the scene about the same time as the Galaxy Nexus.
Just a thought. Reactions?

BLUETOOTH issues CM12, CM13 and other ROMs N7100

hi. I have done so many tests so far so I know what I'm saying.
most used ROMs for N7100 are heavly unstable with bluetooth.
effects are various, from stuttering in a2dp with BT headset to bad reconnecting to low power devices (example smartbands) etc.
again, to connect to some special device I need to reboot many times, for example some kind of internet things.
at the moment the ONLY rom, beside stock, that has a PERFECT manage of bluetooth is:
[OK] ---- [ROM][5.1.1][Haxynox] AOSP for n7100
and roms I tested that has not:
[NOT] ---- [ROM][5.1.1] 12.11.2015 Cyanogenmod 12.1 N7100
[NOT] ---- [ROM][6.0.1] Cyanogenmod 13.0 N7100 Build 8
[NOT] ---- Paranoid Android for Note II(GT-N7100)
[NOT] ---- [ROM][5.1.1_r24][Official][Nightlies]Exodus Android for Samsung note II
[NOT] ---- [ROM][5.1.1][Lollipop][Official][Nightlies] NamelessROM 2.1
[NOT] ---- [ROM] CyanoBiz - CM-13.0 - Doze enable - n7100 / Galaxy Notes2
[continue]
how to test:
there are many methods to test bad handling of bluetooth, most important test with daily use, but to prevent headache you can do in this way.
- pair any bluetooth headset or car free-hand kit.
- play some music to that device
- meantime go to bluetooth option and search for new devices
- if music stutters that rom is affected with bt issues, if not rom will never hurt you and your devices.
so: why I don't stay with Haxynox?
I would but that rom is
a little unstable.
vivavoice volume doesn't work.
bt file transfer crashes.
sometime reboots.
doesn't handle >16GB sd card.
doesn't handle movetosd.
developer is working on CM13 and left this.
please feedback here to have stable bluetooth back!

On RR Lollipop I've had bt stuttering
on dr.ketan kitkat bt was very good
on CM 13 build 7 bt works just fine: tested on mazda infotainment, bt jack adapter, JBL speaker, laptop, pairing with other phone also ok and recently with SmartWatch 3, so I think it's related to hardware if you can't get it to work

thank you for reply. sorry but I don't think is hardware related.
I read tons of thread where n7100 owners wait for a build with decent bluetooth manager. most are still searching for. I was lucky as I found at least haynox build.
so I decided to share this.
did you test playing music through bt speakers and while listen music going to 'searching for bt device' screen?

no, I think when it's paired with device and sound plays well, so there is no need to go there, but I#ll check it this evening

thank you. this may be useful for me.

tested:
[ROM][5.1.1_r24][Official][Nightlies]Exodus Android for Samsung note II
[ROM][5.1.1][Lollipop][Official][Nightlies] NamelessROM 2.1
both have bt issues

yep, I had to go back to stock.. my sony smartwatch 3 was unusable.... I don't like to put my money on trash...

[ROM][5.1.1] 12.11.2015 Cyanogenmod 12.1 N7100
[ROM][6.0.1] Cyanogenmod 13.0 N7100 Build 8
Have problems with bluetooth calls (Static, robot voice), Music player is fine

As I added more bt devices it started to stutter rarely. I noticed that it only stutters when bt is searching, although it's connected.
CM13 build 7.
I believe it's related to data flow, it just can't send/receive that much data simultaneously

ok, after tried so many roms I can say that if you have that stutter bluetooth is less stabile than ideal. can be that you have devices where is less evident. but it's not the way to be:
if you can nandroid backup your note2 and try haynox build. you'll nave stable BT and in test never stutters. in fact there's no way to make it stutter with this ROM. but as said there are other issues..
less than ideal.

[ROM] CyanoBiz - CM-13.0 - Doze enable - n7100 / Galaxy Notes2
my hope for BT was fix by P.A.N. from i9305 github, but NO, it doesn't work well.
waiting for AOSP from same developer

Any news about this?
CM Roms were always weak about bluetooth stream. I have a 6p now and it's happening. On Pure Nexus I'm fine but would love to stay CM

after many devices and settings I came into conclusion, that bluetooth problem is related to android wear app. When I had paired SW3 and allowed Note2 to constantly search for my watch it stutters often, but after uninstalling all that crap, Note don't search for other devices when connected to 1 device and sound doesn't stutter, not even once.
I'm using CM13 build 10

Umm I posted some stuff in Ivan's build 10 rom thread. If you switch network to 2G instead of 3G, bluetooth calling works once again. I tested this about 20 times afterwards and it worked everytime. It even works with traffalguar square's rom.
Hope it helps.

[ROM][6.0.1][v6.18][Beanstalk][OFFICIAL][Great Experience][DU-Features][19.06.16]
This rom have bt issue too.
Still no solution ?

I found a good ROM
I've been struggling with BT Handsfree issue for a very long time. I almost bought a new phone recently, because of this issue. I drive a lot and I really need that function. Samsung original stock rom is so bloated and ugly that it was not an option. Unfortunately non of the CM and AOSP ROMS have fully working BT audio.
I found a solution: [ROM][GT-N7100][TW 4.4.4] Eclipse By AC version 9
It is a stock based ROM with TouchWiz UI. I don't like Samsung interface but this one is really debloated and very pleasant. I think I will get used to it. It's super stable and very fast. I moved to it a few days ago, and my Plantronics M70 headset is finally working like a charm. Just remember to make a full phone wipe before install (including data partition). I had some issues with that.

Bluetooth phone call issues in car

Hey there,
I'm currently running a OP3 with the OmniDragon 8.1 ROM and previously the ResurrectionRemix ROM. However, I do not believe this issue to be a ROM issue so that's why I'm posting here instead.
I've recently been having some issues with bluetooth and was hoping someone could help. I can connect my phone to my cars handsfree system perfectly fine and it works correctly. I can play music via Spotify and any other music player fine.
However, as soon as I make or receive a phone call I'm left where the person can't hear me, and I can't hear them. I can't even hear the ringing tone when phoning someone. However, as soon as I turn it from bluetooth back to the phone or just regular speaker, it works fine.
This previously was not the case when I was running Nougat.
But as soon as I upgraded to 8.1 this issue started happening.
I don't think it has anything to do with the ROM and is actually something to do with perhaps OP3 Firmware/Modem or something similar.
Car hands free works fine with other phones like an iPhone, so that's out of the question.
I've attached a catlog to this post from when this issue was happening in the car, so hopefully someone can narrow it down for me.
Any help is appreciated!

Actually many roms have been having issues with BT calls. It's due to some of the changes in the telephony package.

Hello, did you manage to find any Oreo rom that fixed this issue for you? Would appreciate any tips.
I too have had similar issues with Oreo and OnePlus 3. Using an handsfree Jabra Freeway and the microphone often does not work when I answer or phone someone during a drive. Which is extremely annoying and dangerous.
I had hopes that with the release of some alpha Android Pie roms, these BT issues would be fixed. But the issue seem to persist, at least for my device.
My only fix was to go back to nougat. The most stable rom i've found is the unofficial lineage 14.1 by sultan. This have been my daily driver for awhile now and seems to work fine.

Lineage 14.1 / HTC M8 - BT issue

Hi,
I don't know if this thread is here in the right subboard but please let me explain my issue with Lineage 14.1 for the HTC M8 / single sim.
BT is generall works well with headphones and speaker but I have a serious problem with the phonebook function im my VW car navigation system RNS310.
The pairing is easy, also call-in and -out works.
The problem is the phonebook part: no phonebook, no arrived phone calls, no call history are available on the car system.
I tried it several times since the weekly updates dropped in cointaining less or more system changed but: No success since almost a year ago. Deleting the pairing and re-pairing also no success.
The latest rom "lineage-14.1-20181026-nightly-m8-signed" was tested, too.
Any ideas to help are welcome as the bugbash forum
P.S. The original HTC rom works flawlessly in this respect.
P.P.S. The jira bugbash community is dead on this issue.

Hi, I have the same setup and seems to work with my Mercedes no problems. I have noticed Bluetooth disconnecting randomly occasionally, but haven't worked out if its the merc command system or something with lineage 14

Hi,
that's good for you.
Anyhow it doesn't work in my Golf.
Commercial ROM works as well as other smartphones with factory versions.
So, it remains one of the big disadvantages of LOS 14.1 as well as the HDR camera crashes after second click.
Hopeless.
P.S. A big bunch of patches is forseen for the weekend even some changes in android_bt. Maybe this comes with a solution.

Finally I found a solution: It works !
In settings / apps / system processes I deleted data of the two available BT services.
Then I re-paired the phone and the car and after 30-40 seconds all phonebook stuff was displayes on the car navi screeen.
Case can be closed, I'm happy with the working status.

Redmi Note 8 Pro Bluetooth Issues?

I have been facing issues with Bluetooth on my device. I am using a wireless earphone that has the latest Bluetooth version 5.0 and whenever I call anyone the audio is not audible or distortion is heard on the other end also this happens randomly and range what I used to get on my note 7 pro is reduced. However, I haven't faced any such issue in other devices while using the same earphone.
Anyone else getting this problem. Please let me know if I can do anything to any fix the issue.

Same problem here.
I thought it was the earphone(jvc) but same distorsion on other earphone(pioneer).

yes same here. i use jbl reflect mini 2 and i have constant interruptions when talking. very frustrating. could this be only software?

I use Pamu Scroll, Pamu Slide, Redmi Airdots and i have constant interruptions. One earphone disconnect and i've to turn it down and reconnect tu use it again. Pretty terrible Bluetooth issue.

with another new pair of headset same constant interruptions when talking

Xiaomi we need an update to fix this.

no news, bad news?

Yesterday I received an upgrade.
I will let you know if it changes something.

Try disabling absolute volume in the developer menu if you haven't already.

Same problem here with Xiaomi Necband headset. I tried with 2 sets and same issue. I can listen, there is no problem with audio apps, but when talking there are some problems.
I also tried change bluetooth Latency to long and Bluetooth Playback Quality to connection quality. It works for a while but than it doesn't.
If someone has some other tips & tricks pls share

all good with the new android 10
