BT keeps disconnecting from car radio 5.1 Android - X 2014 Q&A, Help & Troubleshooting

This phone (stock, non rooted) was working with BT fine under 5.01and Kit Kat before it for mostly calls. I know it is the phone because I have tested it now in three different cars, my 2014 Prius, a new Chrysler and Ford. It exhibits the same behavior. Pairing is not a problem. If the screen in on when I enter the car the connection is made. When the screen dims (sleeps) the connection drops shortly thereafter. If I swipe and get the screen back on I can manually re-connect through the car's radio. If I enter the car with the phone in my holster, likely asleep, it will not connect.
Keeping the screen from sleeping appears to "remedy" this issue but that is hardly an option in terms of battery life. Normally I keep the phone in a holster and never had this issue. I have tried every remedy on the Internet. I am using safe lock and have the radio as a trusted device. I have removed safe lock and the same issue ensues. I have unpaired, cleared cache, re-paired etc.
last night I hooked up the phone to my Garmin Nuvi via BT. No disconnect issues.
Any suggestions on further troubleshooting? Any advice on this problem would be greatly appreciated. Thanks..

Work around found
I found an app called Bluetooth keepalive. It appears to have solved my problem for now. Since installing it the connection has not disconnected. The app uses very little battery power

what kind of car do you have? you might wanna look into updating software in your car or at least try it with another phone (preferably the same) just to rule it out

[Q] Car hands free - problems

Hi guys,
I am having problems with car BlueTooth hands free and Samsung Galaxy S:
With Eclair 2.1 it was working flawlesly, connected automaticlay after paired, I could make phonecals, receive phonecals, no quality issue, phonebook worked fine etc... The only problem was that once I did not swithced the BT on my SGS before starting to drive, for some security reasons the car was not searching for phones while driving, so I had to turn the BT in car off and on again and then it connected well. But overal problem free...
With latest 2.2 Froyo (i9000xfjp7) and also previous Froyo distributions (i tried JPA if I remember correctly), the phone can be paired, it connects to the car but after one phonecall it looses connection and works no more. The strange thing is, the BT icon on the phone shows brackets (like when connected) and also the car shows the phone is still connected. But phonecalls cannot be made via car HF and also cannot be received through it. Only by manualy accepting or dialing on the phone. And naturally the sound goes only via the phone, no HF.
The strange thing is, when I turn off the car and leave it, the phone says it is still connected to it, which is impossible.
Any ideas?
Thank you!

That is weird... When I switch back to Eclair, it works OK, back to Froyo, no HF after one phonecall...
I dont know how to work with ROMs, I managed to find out how to flash firmwares, I even handled many problems with Odin and its moods, incomplete flashes, etc... But I dont know how to use these custom ROMs...
Anyway, i would appreciate if someone told me how to resolve it without custom ROMs, as I plan to use offical Froyo when it becomes available, but with this issue, it is useless for me, as I travel a lot...
No one else?
I'm having a related problem.
I'm getting music stream cut outs (1 sec max) when streaming bluetooth to caraudio WHILE wifi on.
If i disable wifi, bluetoothaudio works fine. I know they share range bt/wifi, but this is unacceptable. They should negotiate. Everytime wifi scans, i get cutouts. Unusable. Only workaround is disabling wifi (and thats annoying because i have to be constantly activating/disabling it everytime i enter somewhere with wifi etc.
Using Docrom xxjpo v8 with voodoo.
Anyone has some software fix that makes wifi behave better when bluetooth musictream on?

I always get disconnected with my bluetooth

i have the same problem as some other people do as well. There's no actual fix, afaik, although the gingerbread roms seemed to have fixed it for me.
You can ask in the appropriate Q&A for your ROM.

in his defense - although I could be wrong, I found that it has nothing to do with one particular rom. I had this problem on stock eclair and many of the custom froyo roms. Once I ran GB, the bluetooth was more reliable.
I'm having the same issue with stock 2.2.
I found a quicker method to fix it.
I downloaded a Bluetooth widget that toggles Bluetooth on and off - this seems to reconnect with my Jeep after the toggle:
com.curvefish.widgets.bluetoothonoff
I'm sure there are a ton of widgets out there; but, you may want to give that a try!
Thanks,
Shawn
I also ran into this as after chatting with Samsung support it turns out that the Galaxy line is set to never auto connect to any bt device even if the connection was already there.
I had trouble with disconnections from my car deck (jvc kw-xr810) when it was trying to share contacts. Once I set the phone to deny contact sharing and set up a separate phone book in the deck, it connects perfectly and never drops.
It's not a perfect solution if you want your whole address book access accessible from the car however.

I use tasker for this. I have a task setup that as soon as I turn my car off and BT disconnects, toggle BT off and back on. I noticed that as long as BT is toggled off and back on, it will connect and hold it the next time I use it.
although, I have since turned that task off because GB roms seemed to have fixed the BT issues with my car. I rarely have this problem since switching to gingerbread.
Captivate stock 2.2 intermittent bluetooth problems
I have a stock Captivate with 2.2 android and I'm using a Motorola S10-HD headset to listen to music while I'm at work.
The bluetooth will randomly disconnect causing the music to pause. Sometimes it will reconnect on it's own several seconds later and I am able to continue listening by clicking the play button on the headset. If it doesn't reconnect on it's own then I have to turn off bluetooth on the phone and turn it back on. This will cause it to reconnect but the problem may occur again.
I have switched to listening to music on my Galaxy Tab 10.1 and haven't had any problems so it must be the phone.
Is there anything that will correct the problem?
Is this a defect with my phone or just a design problem with all Captivate phones?

[Q] Issues with Moto X and two Bluetooth devices

I searched this forum and didn’t see any posts related to this issue directly, please direct me to any existing threads if I may have missed them. Sorry for the length of post, but I wanted to be as detailed as possible to fully explain the issue.
I am having some issues with the Bluetooth connections that I use in my car. I had this setup working previously on my Droid Razr Maxx with no issues, and was really hoping it would carry over to my Moto X.
I use Tasker in my car and have several profiles setup based on my Bluetooth connection state. When I enter my car, I connect to my General Motors Bluetooth for hands free calling. This connection works without issue. I also have a small USB powered Bluetooth audio receiver that converts the Bluetooth stream to a 3.5mm cable and goes into the radio deck for audio. It was a pretty cheap dongle that I got on eBay. It doesn’t have a brand name on it, but it comes up in my phone as “dmzmusic”. I’ve never had any major issues with it before, other than on occasion it fails to turn on when the car starts, but shutting the car off and turning it back on again works fine.
Last week I had my phone in a basically stock 4.4 state. Not rooted, nothing changed, etc. When I would get in the car, General Motors Bluetooth connected just fine. I did not happen to take any phone calls last week, so I’m not sure about how well that was working. I’ll get to this in a minute. My other connection for dmzmusic seemed to connect and then very quickly disconnect. This was evidenced by my Tasker profile launching Pandora, which it is supposed to do when it connects to dmzmusic. However, Pandora immediately exited again, and when I went to the Bluetooth settings, only General Motors was connected. If I tapped on dmzmusic in the list of paired devices, it connected and worked fine.
Over the weekend I rooted my Moto X with SlapMyMoto, which was quite a long process, but in the end, I was rooted and all was well. This morning, I got in my car and re-paired both devices mentioned above. When the Tasker profile fired for dmzmusic, I watched it launch Pandora, and then close it within a few seconds (there is an exit task to kill Pandora). It did this cycle three times, and then apparently stopped trying. As with before, I tapped on the connection and it worked fine. It launched Pandora, music played my whole way to work, and Pandora was killed when I arrived at work.
Now, back to the General Motors issue. Today when I was driving to work in the lovely Minnesota weather, my boss called to see where I was. My music paused, but my radio deck did not show an incoming call on the screen. I pressed the hands-free answer button, but it didn’t work. I picked up the phone and swiped right to answer, but it didn’t come through on Bluetooth. So I started talking on the handset, and after about 30 seconds, it connected to the radio and hands-free worked. When I was done with the call Pandora and music resumed, as it should.
So my question is, has anyone else had any issues with hands free Bluetooth, and/or any issues when using a hands-free device AND a media only device? In the Bluetooth settings, my General Motors connection only has the option for phone. The dmzmusic device has phone and media, but I have unchecked phone so it’s set to media only, if that makes any difference.
I know it’s a somewhat unique situation, but it’s really annoying that it doesn’t work. Tonight I am going to test having a few seconds delay on the Pandora task to see if that helps the repeat cycle that it did this morning.
Thanks!

Yup... My Dev GSM Moto X on 4.2.2 connected just fine to my Mazda for both Phone and A2DP everytime I entered or exited the car. With 4.4, I'd have to manually go into Bluetooth and have the phone connect to the car. Very annoying... Haven't had that happen since ICS days.. Might have to downgrade to 4.2.2 again just to make this go away.
Bluetooth working fine on 4.4 with my Hyundai Elantra. Phone and A2DP. Maybe try repairing?

Thanks. I wasn't able to test it on 4.2.2 (it took right away OTA out of the box) with my Moto X, but it was working fine on my Droid Razr Maxx on 4.1.2 Jelly Bean before I got the Moto X.
I will have to try and see how it works with just the A2DP device without the handsfree. I rarely ever talk on the phone, and with the Touchless Controls I could call people and just pick up the phone. Or turn the phone portion back on for the A2DP device so the sound would come through my speakers but I'd still have to use the mic on my phone...
Still annoying. Thanks again for the reply.

Both pair automatically together when you enter the car?
I can get them to coexist, but I have to manually add the A2DP device. The car radio (General Motors) connects fine, but the A2DP cycles and then gives up, it seems.
I will try pairing them in a different order, and temporarily disabling or adding a wait clause to my Tasker profile to see if it works without that.
Thanks,
I have a Dension BT gateway for my car that provides BT audio and hands free. My phone connects automatically as long is bluetooth is turned on. I also connect to a BT OBD2 adapter sometimes, and I tried it today, and I kept playing Pandora via BT and also connected to the OBD2 adapter and had data going from both of them.

Yeah, but they aren't a separate connection I don't think. Pretty sure the one connection handles both.
Seems to be an issue with the A2DP device specifically. I unpaired my car and the dmzmusic device and repaired them both, same result. I added just the dmzmusic, and got the same thing.
I changed my Tasker profile to just flash a toast message to show it connecting and disconnecting instead of firing Pandora to see if that mattered and it didn't. I did not try disabling the Tasker actions entirely to see if that worked.
I have a pair of Bluetooth headphones at home that I may try as well to see if it will connect to those. They fire the same task as the dmzmusic does to launch Pandora when they connect, and kill it when they disconnect.
Hoping this gets fixed, because it's VERY annoying.
Is it possible to submit this to Google/Moto as a bug if it is a larger problem with all A2DP devices?
But it's not a problem with all A2DP devices. Works fine with both my 2013 Hyundai Elantra and my Jaybird Freedom buds.

Thanks. I will try it with the Philips bluetooth headphones as well. The device in my car is pretty cheap. I don't know what version of Bluetooth it has, but it was only about $5. Anyone know of a similar device that can receive a Bluetooth audio signal and convert it to 3.5mm, and is powered by USB?

Well I sort of solved this. There's an app in the Play Store called Bluetooth Auto Connect. This can connect to bluetooth devices with a set of conditions and states, and works as a plug-in to Tasker. I told it to connect to dmzmusic upon connection to any other bluetooth device (in this case, my General Motors hands free). Worked perfectly. Thought you'd like to try it out for your dual device setup.
However, I also have a new issue. It seems the reason my phone call wasn't on bluetooth at first was due to some sort of connection issue with the General Motors unit. While driving home tonight, every few minutes my car radio said Connected. And every time I turned the car screen on to thumb up a song on Pandora, it flashed Connected to a trusted device. Which implied to me that it was disconnecting periodically. No idea why it would do this. Didn't see any setting for it in bluetooth, and battery saver isn't on.
Anyone seen something like this? Will try tomorrow without the trusted device settings to see if that matters....
I noticed a similar auto-connect issue with mine, when I was attempting to troubleshoot the stuttering A2DP issues I'm having. If I have the HFP and A2DP profiles both enabled, they both connect right up when the ignition is on. If I have the HFP profile disabled, and only A2DP enabled, it doesn't connect right away and I usually have to manually force it. Very strange. This whole BT situation on this phone has been a pretty big disappointment for me, since I had everything working great with my GNex (running 4.3) and now it's like I've lost the heart of my car audio system.
I bought the Kinovo BT dongle for my wife for Christmas, so it will be interesting to see how that works with her Moto X. I'm pretty excited about trying out the AptX encoding for lossless audio, but I doubt she will even notice the difference.
Just to give you an update.. I downgraded to 4.2.2 and it connects to my Mazda automatically just fine.. Upgraded to 4.4 and the problem returns.. No apps.. Stock + root. Keep in mind that the problem lies only with the auto connect aspect of it.. Streaming/calls work fine but only after manually connecting.

Did you look at the auto connect app? It worked fine for me. My Bluetooth stopped working for a day or two because I froze a process without realizing what it was so BT wouldn't turn on at all. I think I have to remove and repair both of my devices to get the same setup I had on my Razr Maxx on 4.1.2,
The connecting/disconnection and/or 1-2 minute lag from my General Motors hands-free connection was annoying too. Have to see if that persists. I tried making the A2DP device the trusted one to see if that changes anything.
Really hoping this is something that Moto can/does fix, especially through a Play Store push like they've done with Active Display and the camera app.
not that this is much help for the OP, but my subaru auto connects voice (calls) automagically each time. it also auto-pairs/connects with my TuneLink audio (BT receiver for audio output over headphone/FM).
in the bluetooth settings, the settings button next to your device brings up the paired bt device profile. check to see if all of your devices are registered correctly. for example, my subaru says, "phone audio" and my tunelink says, "media audio".
to help complicate/annoy/support above, i also have a soundbar and BT house phone (cordless). both devices behave the same way my car/tunelink do.

Thanks. I do have the boxes ticked in the device settings for which stream to use. The General Motors connection only has Phone Audio (and it's checked) and the dmzmusic A2DP device lists Phone Audio and Media Audio, only Media is checked.
Did you have these devices setup on 4.2.2 before taking the upgrade to 4.3? Did you wipe in the process? Wondering if that's why @totempole had the issue if he is rooted, he probably wiped the device in the process SBFing back to 4.2.2. If you aren't rooted and didn't wipe between 4.2.2 and 4.4, that could explain why it works OK for you and not us..

Must be something with setting it up AFTER taking the update to 4.4 Kit Kat. Wonder if @totempole tried setting thiers up after going back to 4.2 and before taking the upgrade for the root process with SlapMyMoto?

could be completely device specific too. if your vehicle is BT v2.x or whatever. my tunelink specifically has problems with data/audio stream with the X that my X doesn't have problems with on other devices. could be software/hardware incompatibility issues.
FWIW, my vtech BT phone @ home would NEVER pair with other devices. i would always have to manually pair.
I just emailed Moto about this, because I'm having bugs too. I think that you're on to something, 640k. My Pioneer headunit (FH-P800BT) has BT 2.0, and while HSP connects fine, A2DP only works on the first pair, and after disconnecting once and reconnecting, it won't ever connect A2DP. I have to completely unpair the phone and re-pair it to get both A2DP and HSP working. My phone also gets stuck on "Connecting..." under BT whenever it's having issues connecting with A2DP. Here's the email I sent off to Moto"
I've noticed an issue with my new Moto X that I never had with my Samsung Galaxy Nexus. The phone itself performs way better than my older phone, but I've had a specific bluetooth problem. I have a Pioneer headunit that supports A2DP as well as HSP (music playback and headset functionality) and with my Galaxy Nexus, it worked great, I paired my phone up with the headunit, and both A2DP and HSP would pair at the same time, and work perfectly. With my Moto X, when I first pair the phone to the headunit, it pairs both profiles, but after I've disconnected (turned car off or turned bluetooth off) and come back, it only pairs HSP, and when I try to pair A2DP, my phone gets stuck on "Connecting..." under bluetooth to the headunit, and never will connect to A2DP unless I unpair and re-pair the entire phone. I've tried resetting my headunit and phone and still the same problem exists. Looks like other people are having issues with bluetooth too, as per this article on a popular Android forum > http://forum.xda-developers.com/showthread.php?t=2562186 < I'd like you all to check this out. Seems it's just on 4.4, and wasn't present on 4.2.2 (I never checked myself on 4.2.2, as I immediately upgraded to 4.4 when I got my phone. This doesn't seem to be a hardware problem, but more of a software problem. Please check into this, and don't just read this and act like it's only a problem a handful of people are having. I'd like to have this fixed, and while it's not a deal-breaker for me to use the phone, it does make me a bit frustrated. Thanks in advance!

[Q] Bluetooth Connection Issue (Redux)

Hey All,
I've done a quick and dirty search for this problem, but I haven't found anything that's exactly the same.
I have an XT1060, Dev Ed, on KK 4.4.4, and I'm just wondering, am I the only one who cannot get my bluetooth radio to hook up to paired devices easily?
The problem is, I always have to ask to connect manually; this is a bit of a pain, especially after turning off my car, say, for a few seconds. Oh, it'll connect, but sometimes it takes 10-15 tries before that connection is made, and even then, it's often after I have to disconnect then attempt to reconnect a few times because it doesn't connect both the phone and media modes.
I have done the unpair/re-pair thing a couple of times, but nothing changes.
I had an HTC phone before this, and it'd reconnect automagically to my cars BT server, so I suspect it's nothing to do with the car's BT radio. I really miss that...
Thanks for any suggestions anyone might have in how to remedy this. Fwiw, I'm willing to go through a diagnostic procedure if someone would clue me in to just how to do that.
cheers,
john
I've had issues with the bluetooth and pairing. When I was on 4.2.2 (I think..) it wouldn't connect automatically at all, and I used an app to connect for me. I have a Chevrolet Cobalt and it wouldn't connect to my built in bluetooth for calls or a small bluetooth dongle that I use for playing music through the AUX input on the stock radio.

Once I was on 4.4.2 it seemed to work much better. I have no real issues now on 4.4.4. The only time I notice it not really working right is when I try to connect to the bluetooth speaker in our bathroom at home. If I turn the speaker on, it almost always connects to my girlfriends phone nearly instantly, even though I open the bluetooth menu and tap the paired device to manually initiate right when I turn on the speaker. It usually takes me a few tries to get mine to connect before hers, or I ask her to shut her bluetooth off for a moment while I connect. She uses the speaker every day because she leaves for work after me, so it only happens to me 1-2 times per month on the off chance that I want to listen to music or a baseball game in the shower, so it never really bothered me much.
I think the bluetooth radio in this phone could be better.. I never had any similar issues with my Droid X or Moto Razr Maxx so I'm not sure what the deal is...
Edit: forgot to mention I also have an XT1060, but not dev edition. My bootloader is unlocked and I am rooted, but using the official 4.4.4 VZW rom with Xposed.
I have never had any issues pairing Bluetooth - on either my car or moto 360 watch (even simultaneously).
However, I have noticed that the Bluetooth connects much quicker on custom ROMs when compared to stock.
I think tour connection issue may be a setting or rogue app related.

Thanks to both of you for your replies!
Fwiw, things have not gotten any better since I posted my question. I'm getting more accustomed to it, though.
As for the possibility of a rogue app, yes I suppose so, but short of uninstalling everything, and adding them one by one and trying to connect to something via BT, how can someone go about debugging such a thing?
cheers,
john

You may need to delete the profile for the Bluetooth pairing in your car. Could be a conflict there.
Otherwise, try looking at your Bluetooth settings on the phone.

I have an XT1060, Dev Ed, on KK 4.4.4, and I'm just wondering, am I the only one who cannot get my bluetooth radio to hook up to paired devices easily?
The problem is, I always have to ask to connect manually; this is a bit of a pain, especially after turning off my car, say, for a few seconds. Oh, it'll connect, but sometimes it takes 10-15 tries before that connection is made, and even then, it's often after I have to disconnect then attempt to reconnect a few times because it doesn't connect both the phone and media modes.

Is it *ALL* bluetooth devices, or just the car? What model and year car? Are you connecting to the Hands Free profile, Headset Profile, or doing something like A2DP for music streaming?
How long have you had the phone, how long has this been a problem? Has the symptom ever changed?
Keep in mind, just because your HTC phone connected to the car just fine, doesn't mean the car could not be the issue. While the Bluetooth profiles and protocols should be "standard" I've seen many issues of interoperability issues between bluetooth devices over the years. Especially with car kits.

Guys, thanks for staying with me on this. One thing I've definitely learned is that the bluetooth thing is something I'm pretty ignorant on. I can see that I'm going to have to study it a bit before too long. Gad, that HTC spoiled me rotten---at least in that way.
I haven't tried the phone with any other BT devices. This is mostly because I don't own but two, the car and a travel speaker, and I haven't had the speaker out of its case since I scored the phone six or eight weeks ago. Also, I did some housecleaning, so I have only a small fraction, maybe 20%, of the same apps on the MotoX that I had on the HTC. I have no apps on the MotoX that I didn't have on the latter.
As for some of the car-related suggestions, it's a 2015 Subaru Forester Premium 2.5i, which is really only level up from the base model of that line. I can't find that there is a bluetooth profile setting in the car that I can change; I think that it's too basic. The relevant user manual simply states the following:
Media format
Bluetooth audio devices cannot be
connected if they are not compatible with
the following Bluetooth® profiles.
. A2DP (Advanced Audio Distribution
Profile)
. AVRCP (Audio/Video Remote Control
Profile)
I don't even know what either of those mean!
Anyway, what I did do is go to the phone settings, and uncheck the Media box that shows up once the car's BT server is detected. Then I try to connect with the Phone box checked. It'll still fail to connect several times, but (a) it doesn't take as long to fail to connect, (b) it doesn't take as many tries (it seems) to make the connection, and (c) when it fails, it fails totally, so I don't have to disconnect from 'Media-only Connected (No Phone)' connection. That makes it easier I suppose. Then once the connection is established, it's a simple matter to go back to settings, and check the Media box. That add-on connection happens pretty quickly, but the process is still a little overwrought, imo.
Of course, KidJoe, up until you mentioned a Headset Profile, I didn't know one existed. But when I try to play music on my phone using PowerAmp, well, the app doesn't hook up to the BT anyway. That's a key difference between the HTC and the MotoX. In PowerAmp, I have "Play over Bluetooth on Detection" selected. The headset isn't being detected at all. So maybe that goes some distance to explaining what I'm encountering.
Again thanks to both of guys for hanging in there with me! I'll keep trudging "onward through the fog," as it were...
cheers,
john
A2DP and AVRC are used for Bluetooth Stereo audio streaming (like playing Pandora on your phone via your car stereo). Not phone calls.
For phone calls, usually a Headset or Handsfree profiles are used, and sometimes BT Phone Book Access (so you can see your phone's contact names/numbers on the car's screen).
I've run into compatibility issues between some phones and some Headset/Handfree devices (mostly cars, but a few bluetooth headsets too). Often times when this happens, you're stuck. Each side will blame the other (i.e. Moto will blame the Subaru car stereo, and Subaru will blame the phone).
I have had issues re-connecting to my car (a 2011 Saab 9-4x with Bose/Nav), IF I had my Moto S11 Flex HD headset connected to my Moto X before I got in the car (even if the S11 was powered off/disconnected from the X before I started the car). Usually toggling the X's bluetooth off/on, and sometimes worst case rebooting the phone, has always fixed it.. Another time I had troubles connecting to my Saab's car kit was when my wife was using her phone to stream audio. The next time I got in the car, I had to manually connect my phone. The car always tries to connect to the the last phone used, so it was looking for my wifes and it took a while before it timed out. When it did time out, it didn't look for mine.
Since you have a 2015 Subaru, I would consider visiting your car dealer, ask them to help with pairing the phone properly, and making sure its working right. See what they have to say.
My bluetooth in my car stopped pairing the other day, and it turns out it was an app that updated and requested permissions related to bluetooth. I didn't notice them because it's an app I trust so I accepted the new permissions without really looking at it.
I used App Settings (Xposed module) to disable the permissions and my bluetooth works fine again.
I could still pair with things if I went to the bluetooth paired device list and manually tapped on the device I wanted to connect with, but it would not pair automatically (like when I got in my car). Once I disabled that permission, it started working again without issue.
May be worth a look through your installed apps to see if anything has access to bluetooth and may be interfering.
Hey All,
Thanks again for the continued help!
It's true, I didn't do any research on app interference before I posted this thread topic, but since a couple of you have brought it up, I decided to do a little research. I installed a permissions app, and took a look at the permissions that allows an app to automatically seek out, and pair with, Bluetooth servers. I have to admit, I got some surprises there. (Who would've thought that Beautiful Widgets needed that permission; it is now gone.)
Anyway, most of the remaining apps are either system/Moto-related, or ones I would really like to keep. I'll report back on what I learn. If there are other permissions that I need to reference besides the two pairing-connecting to Bluetooth ones please let me know...
cheers,
john

Anyone having problems with Bluetooth

I previously owned a Sony Z3v and had no complaints. I run and workout regularly so I often use bluetooth headphones while doing so. These in particular http://www.plantronics.com/us/product/backbeat-fit. I'm been having issues since day 1 with these disconnecting. I have to power them down and power them up again to reconnect. Even when they lose connection, they show they are connected but are non responsive. I had not trouble whatsoever with my sony experia.
Anyone else having these kind of issues? I've checked the forums and I don't see any reports. Is this isolated?
I only use Bluetooth when I'm in the shower with the beats pill but it works great for me.

Not entirely related but I have had issues with my original Galaxy Gear disconnecting somewhat frequently when I disconnect my BT head unit or at other seemingly random times that sometimes require me to turn BT off and on again. It's not that huge of an issue usually but BT on my S6 is not perfect for sure.

I am having Bluetooth disconnect issues with my car. Will connect and disconnect repeatedly for about 7 minutes and then stay connected. Very annoying. Have tried several fixes but nothing has worked.
I haven't had an issue with mine when using it for my gopro.
The issue is with Android using Bluetooth 4.0 and WiFi simultaneously. I've had these issues since owning the phone. For whatever reason if you connect your phone to a bluetooth speaker where both devices are BT 4.0, the WiFi will be extremely slow or not work at all.
If you don't believe me, try it. As soon as you connect the device, try to load something like a video or song over WiFi. Or even send a Facebook message. It'll stall. As soon as it stalls, turn off WiFi and it'll magically start working again over cellular data.
No issues here, usually stream to a Bose Color Sound device, getting connection through WiFi
I have issues with mine pretty regularly with my car. A reboot of the phone will sometimes fix it. It's annoying, sometimes it will disconnect from audio but not phone or vice versa. Or it will work perfect, I'll get a phone call and it all goes to crap. The remainder of the drive will generally result in fighting with it. Maybe it will reconnect, but most of the time it won't. Never have I had a phone with so many bluetooth issues.
Had issues with my truck head unit / phone BT. Phone would continually disconnect.
Tracked it down to the Messages transferring to head unit.
If I disabled Messages in the Bluetooth / Allow Access To area, it worked fine, but obviously messages wouldn't go to my truck.
I cleaned all messaging apps, factory reset truck head unit, no fix. eventually factory reset the phone, havn't had any problems since.
