Nexus 7 with 4.2 - Bluetooth issues

Can anyone with a N7 and 4.2 confirm my issue?
I'm using the N7 everday to stream music from TuneIn, Google Music and Spotify to stream to my Bluetooth speakers. I never had issues with Android 4.1, but since 4.2 it's stuttering every few seconds. Especially when the content gets streamed over wifi and is not stored on the N7. To go sure that it's not just my wifi I tried it with my GNex and 4.1 and there I don't have this issue.

Yes, I believe all Nexus 7's will be affected, too. Check out this Google Code bugreport:
http://code.google.com/p/android/issues/detail?id=39633
I am highly disappointed in Google for this. This is a HUGE use-case for me, and it has essentially made my $150 headphones worthless, as well as essentially ruined my use of the Nexus 7 in public, as I cannot listen to music/videos at a public shop/location with the BT headset/headphones that I always have with me. Wired headphones? Ick.

Yes, I've created that issue in the bug tracker. Please star it if you've the same issue. I'm now thinking of going back to 4.1 since I used this feature daily.

I did star it, haha. Small world, I suppose. Did you see this too: http://code.google.com/p/android/issues/detail?id=39632
Very similar to what happens on my N7 on the odd few seconds I have uninterrupted BT audio output. WTF does Google keep doing with their BT stack? This is ridiculous. It is affected BOTH of their flagship devices. I will all but guarantee that the N4 is affected too.

Well since the 4.2 update my nexus has become quite useless to me. I used to use the bluetooth tethering feature on my phone (which I pay for).
Since the update this feature no longer works
http://code.google.com/p/android/issues/detail?id=39637&thanks=39637&ts=1352902123

just tried my bluetooth headset. crackling/studdering issues.
nexus 7, 32gb.

I can confirm the bluetooth tethering issue as well. Sound is stuttering and tethering over bluetooth is impossible. So now we've two big bluetooth issues :/

I have the same issue. What's weird is that it's fine when playing through my creative bluetooth speakers in my kitchen but affects my philips fidelo bluetooth speakers in my bedroom!

Have you checked "connect to device for internet access"?
I'm having no issues tethering to my HTC desire since upgrading to 4.2, but I did notice that i have to check this box every time that I connect via Bluetooth now.

I just tested BT tethering to my Galaxy Note, all is well there too. The audio problems are not acceptable, though. I am not happy at all.

Are you playing music you have locally loaded on the device? This issue is most prevalent with streaming audio such as Pandora, and streaming videos like YouTube. I have tried: A set of Motorola SF600 headphones, Belkin B51 Audio Bridge, and a Plantronics M155, so I doubt it is an audio-sink specific issue.

I have D200s too which are working fine for amazon cloud streaming. My fidelo dock using the same cloud streaming is breaking up so does seem to affect different devices. Maybe they only tested it on creative speakers!

It may be a 2.1 vs 3.0 issue? **** at this point I am just sick and tired of doing Google's own testing for them. This is a disgrace.

I am testing this right now.
I am able to get audio from Audible book loaded on N7 to my Plantronic M1100, no problems. Headset is 2.1 EDR
Also, I have just paired my N7 with my work Lenovo X230 Laptop (Win 7) via BT, Audio is being played through with no issue and on screen controls on laptop are working. Laptop has a 4.0 chip built in.
Edit: Just installed Tunein radio, working on BT Headset and laptop still.

My speaker system is using Bluetooth 2.1 + EDR. Flashed the full factory image to go sure that it wasn't caused by the update procedure ... still the same problem. It's stuttering every 2-3 seconds.

Playing Spotify direct from the cloud

Just gave it a go with Sony DR-BT21G headphones. Play Music and YouTube both worked without problem. These headphones are only BT2.0, for what it's worth. My Nexus was stock 4.1.2 and did OTA to 4.2.

Bluetooth Issue

So I paired the One with my QED uPlay at home and I'm having issues. The phone has to literally be 30cm away from the receiver or the audio will start getting distorted until it eventually cuts off. I have two uPlays, issue exists on both so its not tbe receiver. Also my iPhone 4s has no issues either. I was hoping the One had better audio than the iPhone since it has aptx, but its quite the opposite. Has anyone tried bluetooth music streaming? Is it just a faulty phone?

Bluetooth and Wi-Fi both use the 2.4GHz channel. Asus had issues with the Prime because of its all-aluminum design where they had to greatly amplify the Wi-Fi signal and use diversity antennas to get through it. HTC uses the latter on the One. When used together, the Wi-Fi signal can overpower and interfere with the BT signal. Try turning off Wi-Fi and see if your connection quality changes. You're the first one to mention a BT issue so it could be unique to your device. Time will tell.

I have had a problem with bt connecting to my car (audi a1) I can hear the call but the other end cannot hear me. Going to delete connection and try again tomorrow.

Thanks for the replies. I switched off WIFI, re-paired the device and bluetooth started working perfectly, so it makes sense it was interference. Strange thing is I turned WIFI back on and bluetooth was still working fine. I'll do further tests in my car tomorrow see how it goes. If I'm not convinced I'll just get the phone replaced.

I have also had issues with bluetooth paired to my hands free car kit. Issues have surfaced when streaming music and also when making audio calls via bluetooth.

The One X had a similar issue:
http://forum.xda-developers.com/showthread.php?t=1688538
It could be that when I was first trying the WIFI antenna was stuck on high power, which caused the interference, but when I reset the WIFI it reduced its power and no longer interfered with the BT. I have changed the WIFI at home to run at 5 GHZ, but work still runs on 2.4.

Apparently 1.29.709.4 has been officially released in Taiwan by HTC, so it shouldn't be long before the update arrives to the rest of us (hopefully).

got the same issue...some times I got no lags in audio streaming, but sometimes they are there...until it (maybe) will be fixed I'm using a widget, my cousin has coded for me yesterday . Quite simple solution. If I press the button, wifi turns off and bt turns on...works fine for me, so far

[FIX] Possilbe A2DP Streaming Workaround

Stuttering and skipping streaming are very known issues on many jelly bean devices.
The most times when I listen to music in my car, i do this via bluetooth. So it is really annoying me and some day, I will have an accident, while I am fumbling with my HTC One.
I replaced the audio.a2dp.default.so with one of the Nexus 4 (4.2.2) and it just worked well, but only the first time using bluetooth streaming after rebooting the device.
I changed some settings in audio.conf and it still stutters.
But then, i deactived wifi while the device was streaming and all stuttering and skipping was gone.
So... can someone just confirm, whether the a2dp streaming works correctly, when wifi is deactived?
I want to know, whether this is the only point to get this work and I don't want to change my working mess

is nobody interested in this?

I posted this bluetooth issue a while back on this forum, and the issue is corrected by switching off WIFI while using BT. Apparently the new update which is due soon fixes the issue but only one user has confirmed that so far.
Since I use bluetooth streaming on the car mainly, I use Tasker so that when Bluetooth connects, it automatically switches WIFI off (don't need WIFI while driving and saves battery), and when it disconnects it switches it back on. This way the phone just works seamlessly.

Just turning the wifi off and back on again when I connect bluetooth seems to solve this issue for me.

i can confirm - turning wifi on/off fixes it as well for me (until next time I go bluetooth)

I discovered this a couple of weeks ago too. I was about to send it back too. Cant live without podcasts and audible in the car!

I have the problem that i cant even here any sound on my HTC CAR A100 Car Stereo Clip, even if wlan is deactivated With my old sensation everything is okey..

I wonder if this also improves the bitpool value. I'm noticing on my HTC One that bluetooth streaming quality is not very good. From what I've read it has to do with a bitpool value that it set too low, increasing this value is supposed to increase the streaming quality. Highs sound distorted on my phone over BT I can't believe Google/HTC have not addressed this issue.

I have not been able to solve the bluetooth audio streaming issue by turning off WiFi for my car. It works perfectly fine with my Jambox even with WiFi turned on, but in the car, it does not work either way and I'm using software version 1.29.401.13

I'm running 1.29.401.13 too and it looks like it is working nearly perfect for now. I can remember only one time, when it stopped for a second. Mabye the car radio is facing similar problems? Did you try to update the firmware or whatever of you car radio?

I've tried researching how to update the firmware of my car's bluetooth, but have had zero luck there as well. It's a 2009 Acura TSX.

Did you manage to fix the problem with the A100 as mine is exactly the same, works fine on my Sensation but no the HTC One.

have the same problem:
If wifi is ON and bluetooth is ON, eg at streaming youtube over the bluetooth headset, it stutters and has distortions.
If wifi is OFF and stream a video from the sdcard over bluetooth all is fine.
what i find out:
I use the JellyBean from Quarkx for defy.
The build from 7.3.2013 worked
All later builds, with the new wifi driver had this problem.
But its a known bug that JellyBean has a2dp issues, i guess.
This trick, to change audio.a2dp doesnt helped me

I didn't noticed any problem with my phone even when the wifi ON, I'm using the latest radio "4A.16.3250.24_10.38.1150.03L" found in this post: http://forum.xda-developers.com/showthread.php?t=2245615

Bluetooth Audio Stutter / Skips

I have received my T-Mobile Note 4, and I have the infuriating problem of random Bluetooth streaming skips / stutters. Does anyone else have this issue? I know it was a known problem on the S5's, and it never really got fixed...
Does anyone have any solutions for this? I checked out the ViPER EQ mod, could that help?
Currently I am 100% stock (latest version, got the T-Mobile patch right away), and I only use Spotify for music. I have experienced stutter in my Nissan, a pair of Sennheisers, and a Monoprice Bluetooth adapter. What's also upsetting is that the stock Samsung music player often starts playing when a Bluetooth streaming device is connected...
Any advice?

I am having the same issue. I really don't know if this is an issue or not. I drive charger and my M8 was the same. It's annoying I feel ya. hopefully someone can tell us how to control this thing.

i've had that issue since HTC One...
not sure if i ever saw a way to fix this issue.

It's funny because I'm coming from the M8 and it was flawless for me. That is was running 4.4.2, whereas this is 4.4.4... Any correlation?

I really don't know if this an issue. My M8 4.4.3 and had same thing. But to be fair Note 4 is more superior inside my car. I am able to listen to my text msg. Voice commands works really good on note 4.

I have this issue from time to time on my Nexus 5. I have to reboot it to fix it. It happens maybe 1 out of 30 times I use BT headsets. Enough to be annoying but not a deal breaker. I am beginning to think this may be an Android issue and not Samsung. Those that have the issue on Note 4, does a reboot fix the problem?

Every now and then when I play Tunein Radio Pro, it would be a hick up. I already did the 30 sec buffer. But usually it works. Is this what you mean?

In my Jeep Wrangler I have BlueTooth. Every few months when I get a new device, I always have to call my mom for the BlueTooth test. The Note 4 has been the only phone to pass. For whatever reason my mom's phone would always sound like I was in a tunnel with the exception on the Note 4. Even the LG G3 failed this. In my 2012 GTI I had issues with some devices as well as my 08 WRX. It always came down the the BlueTooth stack for phone call quality and skipping and sometimes just dropping/crashing out of BT all together. Hope you guys get yours resolved. I know this is a huge problem. Heck when Note had its recent update, I was worried it would break something its just been too good so far! Best of luck guys.

I believe its a kitkat bug. It happened on my note 3 as well

Might warrant a return.
This is so annoying. I'm coming from an M8 (and previously M7) and use bluetooth for everything. Wireless headphones at the gym, wireless speakers at home, media in my car, and a Moto360.
Never had any skips/stutters on previous devices through any of these. Moreover, sometimes the music just STOPS and drops the connection and I have to repair the two devices in the middle of a workout. Is anyone experiencing the music STOPPING? Might return/exchange mine if not.
This happens through any media app - GPM, Milk, Netflix, etc. Want to throw my device.

I am having this issue in my Outback, but it is not happening in my WRX. I was thinking maybe it just doesn't like one, but now I see this is a larger issue. I haven't had this problem with my S5, so maybe it'll clear up when some Roms are released.

I'm having the same issue with my wireless Bluetooth headphones. I thought it was because I was too far away from the phone, but I'm having the same problem when I'm close to the phone also. My Note 3 does not have this problem.

I used my like at least 6 years old Bluetooth headset for like the 4 hours and in that time I barely had skips it only skipped when I left the room and went a few feet away also
Sent from my SM-T210R using XDA Free mobile app

same here
I'm having the same problem

I find this happens when the screen is off. When it's on, no issue. I hope an update fixes this soon.

This stopped after I went to Firekat Rom. Not sure why or how, but Bluetooth is smooth now

Just wanted to verify if anyone is NOT experiencing this issue? If there are Note's out there that are not experiencing it then I might exchange mine. If this is a software issue for all notes then this blows.

As I reported before, I had a similar issue on my Nexus 5 and rebooting would fix it. It was a rare occurrence but it would happen from time to time.
I have not experienced the issue at all on my Note 4 in the 8 days I have had it. I use BT quite a bit with my Heart Rate sensor and BT headsets while running and also connected to my stereo in my Sonata. Has been flawless so far.

This might have something to do with S-Health. Audio skipped for me every 10 minutes or so. Didn't matter the BT equipment. Yesterday, I decided to Disable S_Health. Today, at the gym, about a 90 minute session...no skips. The guy above using FireKat, by any chance that rom has S-Health disabled/uninstalled by default?

Marshmellow Bluetooth Phone Issues?

As soon as I updated to Marshmellow I instantly starting having issues with my audio quality via bluetooth car. On 5.1.1 voice quality was fine, but now it sounds almost like it's out of phase and skipping badly. Is this a known issue, if so, is there a fix?
Thanks!

I use BT in my truck every day. I haven't had any skips that are consistent. Every once in a while, I might hear the audio drop for a split second, but I don't find that it's worse than it was before. I use mine for music and voice calls. I never have any trouble with voice calls. I've always had those little random split second drops with any phone I've had, so I figure it's my stereo.

This sounds more like someone put the whole car underwater and is trying to speak with their mouth full of water as well. I had no problems before when I was on 5.1.1. I've tried a customer 6.0 rom and it has the same problem. I'll try going back to a 5.1.1 rom and see if still does it.

Audio streaming from something like Spotify is not affected, just when the car is used as a headset.

Thanks for trying. I went back to Lollipop and the issue is gone. Definitely a bug in Marshmallow.

My experience was opposite. Bluetooth sound quality was horrible on 5.1. After updating to 6.0 all problem went away. I was extremely happy with their fix.
