Random reboots using Bluetooth - Moto X Q&A

I had an issue with a New Potato Tunelink and choppy audio (I have a thread in here somewhere).
I bought a Kinivo BTC450 Bluetooth Hands-Free Car Kit and it does not suffer from the same audio problems, it sounds great... when my phone isn't rebooting.
The only time my phone reboots is in the car. I've disabled Active thinking it might have something to do with that, but no. If I turn off BT the phone doesn't reboot. There is something with my VZW MX and this Kinivo paired together that creates a situation where it unexpected and randomly reboots.
This morning it rebooted almost immediately after connecting. Sometimes I can manipulate the controls, pick a song and start playing it and it will reboot shortly thereafter. Other times it won't reboot and will start working until I go to skip to a song or something. There is no pattern other than BT and this phone hate eachother.
It's frustrating because I don't know when it will reboot. There are no options that I can see to try at this point other than look for something else or plug a stereo miniplug into the MX, which I'm not a fan of doing.
I've not done a factory reset due to the time and inconvenience of getting it all setup again. I've not tried to have VZW replace it.
Any ideas?

Well, a factory reset did not fix this problem.

I've experienced the same thing, but only twice and I connect to bluetooth multiple times per day in both the car and a standalone headset. I can't see any pattern, but it would certainly be nice to know how to prevent it.

I was having trouble with random reboots and I think it was the Updater app running in the background that may have been causing it. I saw that app running, went to Settings and checked for updates (obviously no updates yet). Ever since then, no random reboots. I use Bluetooth every day with a headset and Car audio device. BT working way better than any CM ROM I ran on prior devices.

[Q] Bluetooth/sound malfunctioning

Got Note 3 on launch day. Worked well until a few days ago when all attempts to use my Bluetooth speakers (Jambox and Big Jambox) began to result in the sound coming nearly inaudibly from the phone speaker. Additionally, when I attempt to use the auxillary jack in my car through the headphone port on the phone to listen to audio, the sound now comes out the car's speaker phone unless I turn off Bluetooth (on the phone). Even worse, after I attempt to use Bluetooth, the volume on the phone is stuck at approximately 25% of normal even with the all the volume sliders at maximum until I restart the phone. I have performed a factory reset without any change. I have unpaired and re-paired all three Bluetooth devices I use. Any ideas on how to fix this or do I have a faulty unit? Any help would be appreciated.

Finally...found someone who is having the same problem as mine.
yes.. im getting pissed off because of this to. Had to do a factory reset for nothing. Didnt fix it at all.
when i get into my car and turn the bluetooth on ... open the stock music app...it says "unable to play during call". Using another music app will result in the sound coming from the phone speaker (the one to use for calling)... reseting the phone makes no difference....
this is really annoying..

I did not have this kinda issue with the old version that came with the phone. After the newest update, it's kept on happening. So I guess its because of the update....
"the volume on the phone is stuck at approximately 25% of normal" => This actually is the reason why we can't play music. The phone thinks that we are on a call.
Your point about the volume rocker showing the call symbol is exactly what was happening in retrospect. And the phone, while it wouldn't play media files, would still connect for a phone call. This is all past tense because I swapped that phone out tonight and am really hoping that will do the trick. One would think that if this was due to an update, a whole lot more people would be having trouble.

Unfortunately, the new phone is acting like almost exactly like the old one now so software it is. I have found a couple of work arounds but hope they will be only needed temporarily.

Found an idea on another forum that seems (so far) to have solved my problem. One of the folks on the Android Central forum noted that when the text+ app was set to take incoming calls, the Bluetooth got wonky in exactly the same way mine did. When I unchecked "Enable incoming calls" in the settings of the text+ app, my phone started working correctly again (so far).
Same issue

Your not alone this a many of several none issues on this phone. When i stream music from my bluetooth headset the audio is minimize to a set volume and I'm unable to increase it.
Fixed
I have had no further problems since changing the setting in the textplus app. I would consider my issue solved!

Hahahha REALY ???? I'm using Text+ TOO
Let me try that ! Thanks a bunch for that
This fixed the issue for me too. Thanks!
also fixed
Had the same issue, using a galaxy s3 took the 4.3 update and the problem started.
turns out it was text plus, I had to log off of text plus , all good once again. I'm going to uninstall text plus and re install, see if it helps, if not, I don't need that app that bad.

Hangouts is in call in the background
I was getting the same error "Unable to play during call".
By killing Hangouts from Application Manager, music starts playing normally.
I turned off Hangouts to permanently resolve the issue.
Hit Thanks!, if it helps

Strange bluetooth issue

My AT&T GS5 will connect to my car's Sync system fine, but when I play music or audio, nothing happens. I have verified with Spotify and Stitcher. This only happens once in a while, but when it does, a full reboot will not resolve it. To be clear, the track plays (progresses in the status bar) but no audio is output. Anyone have this issue?
I stream music through bluetooth devices all the time. Not once have I had this issue. Maybe try turning the volume all the way down then back up? Seems like they have some bad S 5's out there but not all of them.
Try turning the volume up
Sent from my SAMSUNG-SM-G900A using XDA Premium 4 mobile app
So I got a new S5, and am having the same issue. Maybe it is a problem with my car? Rebooting the phone will allow it to connect, but music won't play still. Will have to take the car in.
Though one thing leading me to believe that there is an issue with the phone is I try to turn bluetooth off and back on to connect to the car. When I do this, bluetooth turns off, but will not toggle back on without a reboot. That is definitely an issue with the phone, no?

What Could Cause Bluetooth Audio Stutter? [6.0.1]

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?

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...

Crazy, useless Bluetooth on new device?

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.

Weird problem, no "media" related sounds. Alarm, calls, ringtone work perfectly

Weird problem, no "media" related sounds. Alarm, calls, ringtone work perfectly
Hello, for some reason in the last couple of days i can hear no media related sound.
What's weird though is that i can hear normally call sounds, phone ringing and alarm.
The issue started while on the latest version of MIUI. I thought this was related with operating system so I installed Pixel Experience 10 (through complete wipe out, even internal storage). The problem persists there as well.
After looking around, it looks like people had similar issue when the phone mistakenly thought headphones were connected. As it turns out, this is not the case with me. (see 2nd post)
Edit #2:
It looks like it's indeed the "earphone mode" thats causing the problem. Using the aerphone mode off app I managed to get media sound playing again. The problem now is that as soon as i close the app, earphone phone turns back on. Any ideas for permanent fix are welcome.
Thanks
looking around, it looks like the phone might somehow got stuck in like "headphones connected" mode.
I've never connected in the past with any kind of headphones, but i got the charging port changed.
In any case i've tried connecting and disconnecting with Bluetooth headphones but didn't solve the problem.
I will see if i can get my hands on any type-c ones and try again.
Edit: i see there is an option to select the audio output device, and the phone is the only choice, so the headphones mode wasn't the problem
