Hey everyone,
I've been battling this issue since Day 1, and its been a bumpy road. It seems as though this is a widespread issue across many Android devices, and fixes range but none of them seem to completely eliminate it.
When connected to Bluetooth audio, certain devices, the audio stutters or "skips". Ive noticed this extensively in KItKat. One fix for rooted devices was to increase the idle CPU frequency, I did so with Tasker and it definitely suppressed the stuttering, but did not completely eliminate it.
One of the most notable points of stuttering is when you answer a call via Bluetooth, then hang up. After hanging up, and music resuming, there is a solid ~10-20 seconds of constant stuttering and skipping until playback returns to normal.
Imagine my surprise when I upgraded to 6.0.1, and had absolutely no stuttering without increase CPU frequency or anything! Just buttery-smooth playback, all the way through, even after hanging up a call.
However, a couple of weeks after, the issue came back again. I had to re-enable my task to increase idle CPU frequency, and that horrible stutter after hanging up a call is back, strong as ever. To me this indicates perhaps something I modified after stock interfered., however nothing I can think of should come close to affecting it, other than XPOSED (however, XPOSED was installed prior to this issue coming back up, and no new modules were added)
Additionally, since Marshmallow, my phone won't reconnect automatically to my head unit. For example, when my car is on accessory mode and the stereo is on and BT connected. When I start the car, the system momentarily turns off for ~5 seconds at most, and turns back on. With Lollipop it would automatically reconnect, here is causes some serious problems as the only way to get them to reconnect after is to turn off the stereo and the phone, and turn both back on again. Sometimes I even have to do a couple of cycles.
Does anyone have any ideas?
i tried to do everything possible to fix the issue... I have a stuttering keyboard as well... anykeyboard I use seems to stutter, it lags a little, but most words that i type apear two times...
I have no issues at all like that, or stuttering throughout the system. It is specifically related to Bluetooth audio.
Anyone?
I've always thought kernel

If you do not have this problem, what kernel do you use? I just flashed BeastMode today, hoping that will bring me a bit of luck. However as it worked initially and a few weeks later broke down into the pathetic mess once again, I have my doubts
I use power amp and in advance I set thread priority to the highest and audio buffer to 750ms. I've used them all and haven't had skipping

Seems to have improved it, but reconnect issue is still present
The reconnect issue may be related to the stuttering.
The unit may be also trying to download contacts at the same time which causes the stutter.
Have you tried unpairing it from the unit, renaming your phone and then pairing it again?

I have in fact tried to re-pair the unit many times, to no avail. Factory resets also yield no benefits. It is set to auto download contacts, I'll try to disable that option to see if it improves anything.
I have the stuttering almost removed, however it still sometimes occurs. On a recent long-distance road trip, it randomly started stuttering after playing flawlessly for 1.5 hours, it was incredibly frustrating. I rebooted the phone, and the stereo, reconnected and it started playing smoothly again. Keep in mind however this is with both raising idle CPU frequency, and changing the poweramp options mentioned in Post #7
Perhaps I should try a custom ROM?
You can also try stopping media scanning. I think there is a xposed plugin
I only notice this on a non-name-brand headset. (Also, after it happens, I disconnect and reconnect...and it works fine from there on out...until Power down) My other 3 don't have this problem. Music plays, get a call, hang up, music pick right up. Didn't read your post in detail to see if you've tried a different pair of BT receiver.
FWIW it's not just you, also use PowerAmp, have the buffer turned up, and also get stuttering. On pvsgh's stock rooted deodex'd debloated 5.1.1 with beast mode 1.92 + ZL fix and both my motorola s10 headset and sharkk speaker stutter from time to time. It does not seem to be universal. In the beast mode thread it bluetooth audio issue was brought up, but didn't really get much attention ::shrugs, palms up:: I even limited them to media only but still get the stuttering.
Like so many things it seems, it worked ok before the MM update (910t3 on dok2 ootb) and now doesn't. Kinda like my ability to sign into enterprise level (work - EAP login) routers...
CM12.1 didn't make a difference in my case. Been on several stockish 5.1.1 roms as well. It still happens. Swapping out roms doesn't appear to pay off. It hasn't for me anyway :-/
Interested to see if a solution (or a cause?) lands here...

I just got a 128 GB OnePlus 3T a few days ago to replace a dead Nexus 6P. So far I'm very happy with the phone (performance, screen, etc, camera is almost as good, blah blah) except one thing.
My bluetooth is completely nuts. Sometimes I will turn it on via Settings or Quick Settings and it will not turn on at all (the slider moves to the right but stays greyed out, then moves back to the left). Other times I am "luckier" and it switches on and begins scanning, and I can see devices in the area. I pair to a speaker dock via NFC or my wireless headphones via tapping on them and the connection is established, you can hear the speakers go "hey something connected".
So that's all fine. But then you start playing music. About 40-60 seconds in it will skip, crackle, or pause the music entirely. Sometimes the device makes its disconnect noise immediately followed by its reconnect noise. At this point pressing 'play' again starts the cycle over again, usually, or sometimes it will just refuse to "talk to" anything any more until you reboot the phone.
The phone came with OOS 3.5.4 out of the box and immediately got an OTA to 4.1.1. I was suspect about the upgrade procedure and sighed and did a full reset and re-flashed the full 4.1.1 image using adb sideload, logged back in, did the barest of minimum updates to the Google apps to make it stop complaining, and then tried music again. More skipping and pausing. My headphones have a volume up/down key on them, pressing that pretty much immediately results in a disconnect.
It's like the AVRCP (command) bluetooth protocol is "fighting" the A2DP audio stream protocol? It doesn't make any sense. This would also explain why my car audio has NEVER worked, because my head unit uses AVRCP to read track names and my headphones and speaker dock don't have any sort of screen to speak of.
I want to love this phone and don't want to pay double for a similar Pixel, but I might just have to return it if it's effectively useless at one of the main things I have a phone for! :crying:
Hmmm...My Bluetooth connection never have that issues. I used Bluetooth headphones and my car head unit. Running oos 4.1.1 as well.
Try dirty flashing your ROM, there might be something wrong with the drivers. Bluetooth commands (volume, pause, voice assistant, skip, etc.) work find on my headset, I don't believe its a compatibility issue.
If that fails, it might be a hardware defect?
I don't have problems with Bluetooth im using sony wireless earphones everyday. Try reformat the phone
Hi!
Android Nougat has heavy issues regarding bluetooth connectivity. If you Google it you will see...
I have the very same Problems like you with my car radio...
This must be finally adressed by Google.

Huh? Must be an compatability issue between the BT device and your phone. I have 6 active BT devices I use all the time with this phone and my tablet. Car stereo, fitnessband, speakers and inear plugs.
Only issue I sometimes face is the 'stuck in connecting to last used device' where BT needs to be turned off and on again. Wouldn't call it a heavy issue.
bluetooth perfect here. better than my lg g3 that i had previous.
So, more info. If 2.4 GHz WiFi is active in ANY WAY, the bluetooth goes nuts. AVRCP (bidirectional commands) make it worse. Putting the phone in airplane mode to disable the "ambient" wifi location scanning and such, then turning bluetooth on manually and playing some downloaded music, seems to work fine. Switch the WiFi on though (even though my access point is 5 GHz), bam down the toilet. Ugh.
I did a complete reset and flashed OOS 4.1.1 from adb, no improvement. I'm trying the Open Beta 4 right now but I doubt it will be any better.
Did you turn off the scanning feature?
Happens to me like once every 3 days. I usually reboot by then

Hi, I have the exact same phone and been having stuttering performance with Bluetooth and Sony MDR-X330BT and worked fine with the 1+ 3. I decided to tell the phone to forget the headphones and start afresh; big mistake headphones kept refusing to pair. I noticed they have the NFC symbol on one of the earpads so I enabled NFC and used app I had downloaded a while back, 'Tap-and-Pair' that did not work either. I did a search today and found a great app that worked - 'NFC Easy Connect' from the Play Store. Now all I need is stable connection from car system which appeared to be tied in with length of screen life before going to sleep but think it may be faulty Twingo as been on the car forum and found others with similar issues but different smartphone to the 1+ 3T. Hope this helps.
I've just recently switched to a Samsung S10 (about a month ago) and keep having this issue. I set the media volume to 10% and then, all of a sudden, I'm browsing through facebook and BAM, volume is at 100 and a loud AF sound is playing and I'm in public (since then I disabled the start videos with sound on FB). It is weird to me because when I was using my old Huawei P20 I did not have any type of problems like this, but, nonetheless, I went over all my apps and uninstalled any useless stuff and all apps that somehow relate to sound and music.
Every time I disconnect from bluetooth my media volume resets back to 100. I even set a MacroAndroid to set media volume to 0 when I disconnect bluetooth and it STILL sets it back to 100, almost as if it is fighting the macro to get back to max. This happens on all my bluetooth devices too, it is not exclusive to one.
I unchecked the "use volume keys to media" trying to fix the issue and also turned the volume option on Developer Options -> Networking as well, to no avail.
Does anyone know how to fix this? I have gone through every setting and searched all over google but still coming up with nothing.
Appreciate any help in advance.
Have you figured it out?
I am having the same problem and it is extremely annoying. It happens to me in the browser, but also with Spotify...
Thanks!
very weird issue. stuff like this is usually only ever resolved with a factory reset and if that doesnt do it, its probably the bluetooth stack overflow having issues which is only resolvable by flashing the factory firmware in Odin.
Same problem here... Did anyone find a solution to this problem?
This is a bit of an odd issue but I've noticed occasionally that when listening to media using the speakers at low volume (below ~1/4), occasionally one speaker cuts off or channels swap. It also seems to be random which speaker cuts off but usually the left speaker is the one to cut off. If I turn the volume up, the speakers/channels restore and I can turn the volume back down.
Anyone else experience this?
I take it no one has encountered this? Although since the latest system update, I've not had it occur nearly as frequently.
Makin' an account to add that I've been encountering this issue since I got the phone at end of July. I've seen a few reports on other messageboards of people experiencing this, too. Have you had any luck with resolving it?
I've been trying all sorts of things to try to fix this. Sony Support has unfortunately not been able to provide a solution.

Unfortunately, I still can't pin down why this happens nor have I found a solution, just the temporary mitigation of turning up the volume for it to start working again and then turning the volume back down.
could be a hardware fault
I got the OTA and one of the issues I ran into was actually listening to any media app ( Spotify, Youtube, YT Music, etc. ). Whenever I turn the screen off, the audio stops and when you wake the screen to unlock it has a terrible slowdown. I tried this in Safe mode and even factory reset and the issue is still there. I does not happen with the screen on if you're watching a video, etc. only when the screen goes off. Anyone else having this problem?
Edit: I think I found and workaround for this and was driving me crazy cause I listen to a lot of podcast/music whie driving Go to settings/system/developer options/default usb configuration/ and switch it to " no data transfer ". DO NOT tick any other option.
Yes, I am having the same problem, and since I use a wired headset for work calls all day, this is a significant problem.
Your work-around appears to work, but this needs to get fixed.
I have the exact same problem on my Pixel 6 since the March update, identical symptoms including the massive slowdown, and it's infuriating. While doing tests to try to find a work around it suddenly also blasted to 100% volume for some reason causing hearing damage.
April update fixed this issue.
