Bluetooth Constantly Drops - Nexus 7 General

This is nothing new to my device, but am just now looking into it. I have it "installed" in my dash and use it to stream media through BT to my car stereo. Unfortunately, the BT on my n7 is very inconsistent. It works fine when connected, but will disconnect quite often. Sometimes it disconnects when I change tracks or when it changes tracks on it's own. Sometimes it disconnects when wi-fi drops. Sometimes it disconnects out of nowhere.
The fix is to turn BT off then back on. Obviously, this is a huge pain. I'm using Tasker to somewhat circumvent the issue although I'm sure I could use it to do more.
Any fixes out there for this? It's not my head unit in the car either. Every other device works flawlessly when connected through BT.

Well 4.2.2 did have issues with Bluetooth, I haven't experienced them in my n4 though.
For ****s and giggles you could try a 4.1.2 rom

Thanks for the reply. I had the issues with 4.1.2 as well...At least whichever version of android it shipped with.

[Q] Car Bluetooth: Problems connecting

Here is what I see:
1. 1st time pairing - Both phone and media audio work fine.
2. Next time whenever I would get in the car: Nothing connects automatically. I try to connect manually from the phone, and it takes a while, and media audio connects. Phone audio fails.
3. Now if I go to advanced options and uncheck and re-check phone audio, it seems to connect most of the time.
4. If I unpair and delete the phone from the car's memory, and do it all over, it works for the first time, same as above.
Phone is running stock HTC stuff, no root etc.
Car is Subaru Impreza 2011.
My HTC Aria used to connect both phone and media automatically each time flawlessly. (Running CM6 and 7, <never got a chance to try with stock )
Any pointers would be great!
Thanks
Might be a car problem. My last 2010 VW GTI had a finicky bluetooth. You could stream audio and take calls, but if you walk out of range of the BT while the car is on and walk back in range it won't connect until I reset the head unit. However in my 2011 BMW, I can walk out of range and it instantly connects to my phone when I'm back in range. Connects every time without a flaw (even though I did have some occasionally difficulty with my iphone and bluetooth in the BMW)
I have exactly the same problem as described by the op. Not sure what to do but I don't talk much on the phone so it's not that big of a problem for me. If it was the other way around it would be much bigger problem. Anyone has suggestions? I woud like to make it work as it should.

For you also, does nothing connect by itself? I'd be somewhat happy if atleast media connected automatically
Once we have a good permanent root solution I'll play with tasker to see if I can create a workaround...but this sucks!
Raider
I have a Rogers Raider and it works really well with my Kia Sorento. I think it is the vehicle or both. Both meaning compatibility issue. I had a Samsung Vibrant (i-9000) and it worked but sometimes it doesn't connect and always seems to upload my address book which takes a long time. With this Raider, it works like a charm. The Raider works before and after root.
Did you check your vehicle Bluetooth vehicle compatibility chart? They might have one.

I have a 2010 Hyundai Sante Fe (similar to the Sorento). After initially pairing my Vivid to the car's bluetooth, the two have always connected, reagrdless of whether I turn on BT before or after I get in the car. I also had no problem with the old HTC HD2 (WM6x) and the Santa Fe's bluetooth.
Have you tried un-pairing the phone and car and re-pairing?
Everything works fine with mine too. I have a Toyota with BlueLogic. I used to have this problem with my old device, Motorola Atrix, didn't connect most of the times. I checked many forums and I found out it is a Gingerbread problem, with Froyo everything worked flawlessly.

I have a Subaru impreza 2011 which has Bluetooth in it, and I just bought an htc rezound. I run all my music via Bluetooth so this is a pressing issue... It pairs and connects just fine the first time but I have to erase the Bluetooth memory on my phone and my stereo and re pair everytime I get in my car. I used go have an iphone and it worked fine. I checked my phone with a Bluetooth headset and it acts just like its supposed to. Any suggestions?

Same symptopm..
My only hope is that the BT libs of CM9 will do some magic
What's CM9?
Mine seems to automatically connect just fine. However from time to time, very few times, the sound won't work right off the bat. If I press the volume rocket it will play a sound. Sometimes I have to press it twice then the sound will come through the speakers and music will play just fine. It's strange and quirky, but eh. Lol so if you're suck without sound, try to adjust your ringer volume to stimulate the sounds before repairing. See if that works.

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

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
I don't know if it can help..

[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!

Anyone having Bluetooth connection issues?

Trying to stream music from Google Play to my Big Jambox over Bluetooth. Sounds like a CD is skipping and then it eventually pauses the music.

The only problem I have is the bluetooth in my car is always on. The phone wants to stay connected to it even when I'm in the house. Makes for a frustrating time when I'm doing work in the yard and trying to listen to something. I will plug in the headphones and after a while it will switch to the car's bluetooth.
Short of that the bluetooth connection has been stable and used a lot.
Can anyone help me..

Blue tooth connection issue
Ok, let me be as descriptive as possible to my condition/experience.
I went for a walk today with Droid Turbo in tow, blue tooth connections to my Moto 360 (synced with Run Keeper) and Beats bluetooth earphones, playing a downloaded podcast, to avoid weak signal/streaming issues.
The sound coming thru the connected headphones was choppy, cutting in and out. Not listenable.
I thought the Moto active display were being tripped over and over again in my pocket, causing the choppiness of the bluetooth audio.
I turned off all the Moto active settings, as well as double twist to open camera app.
After turning off all those settings, it seems to play without a hitch. For the first couple of minutes. Then it would alternate between continuous playback and chopped playback, couple minute at a time, back and forth.
I am now done with that walk, sitting down typing this up and bluetooth thru Beats are working flawlessly.
It must be related to motion of the phone as I walk that causes the chopped playback, i dont have a clue.
Anyone have similar and create a setting profile that eliminates this?
Only issue with Bluetooth is with my mazda cx5, connects faster than my note 3, plays well except sometimes with play music the display won't advance to the next song but the song plays. Also sometimes the skip track won't work. Had zero issues with the note 3, hoping the next update fixes these problems. That's the problem with being an early adapter, but love the phone so far, miss having viper4android and pandora patcher, but can live without them, but keeping fingers crossed for root, although I seriously doubt this phone will get it.
Me too

I had what sounds like the same problem. At first I thought I was getting notifications that would make the Bluetooth connection to my car cut out, but eventually realized that it was indeed garbled and sounded like a CD skipping quietly. I also had horrible battery life and touch screen issues even after a factory reset. Returned it and I'm using my GNex until my N6 shows up.

Fortunately for me the CD skipping stopped. Seems it worked itself out for me. [emoji1]
My turbo has a terrible time staying connected to my pebble, so much so that I'm attempting to set up llama to periodically check for connectivity, and if it finds none, reset Bluetooth and attempt a reconnect.
No audio problems, but I've never tried for more than a half hour or so.

I have this same stuttering problem when I use my LG TONE while everything works fine while connected to my car's radio.

I run regularly with the Turbo in my pocket, with BT Headphones (Motorola H11), BT heart rate monitor (Polar), with Runkeeper app tracking my run and music playing from Google Play music. Works very well. Once in a while, I do get a little skipping (1-2 minutes of skipping on 1 out of every 5 runs?). I do usually turn my wifi off when I'm going for a run. I run by a few saved hotspots, and I think that the skipping is related to wifi attempting to connect to a weak hotspot.
Just curious... The ones having issues with BT connections. Are you by chance connected to Wi-Fi? I've always had issues with Bluetooth on my devices when connected to 2.4ghz WiFi. No issues with 5ghz. They're too close to the same frequency. My note 2014 can't even keep a connection to my work 2.4ghz Wi-Fi and stream over a Bluetooth connection. Drops it every time.

Yeah I'm pretty sure that's the issue here. When I first got this phone, music over my bluetooth earbuds would skip like crazy while I was walking across campus. Eventually I noticed that if I set the wifi frequency band to 5GHz only or turned it off completely, then the stuttering would stop. Likely the stuttering was from my phone trying to connect to access points as I walked through campus. So now I just have tasker set up to disable the wifi whenever I'm connected to my earbuds. Not a proper solution but it works for now. Never had a problem like this with my Galaxy S3, though. Hopefully it can be fixed in some sort of software update.
I've had what sounds like skipping, but it only happens when the phone is either connecting or disconnecting from WiFi and I am streaming music, that wasn't uncommon with previous phones though so I wouldn't consider it a Turbo issue. I stream almost every day for a total of about 1-2 hours.

Hey I just posted my experience here http://forum.xda-developers.com/showpost.php?p=57604084&postcount=4 but I'll just copy and paste it to this thread:

Rixanu - I think you're on to something... I'll give my "story" and hopefully someone a little more savvy than us can help figure it out.
I switched over from the good ole Galaxy Nexus about a month ago. No major complaints on the Turbo yet as we await Lollipop, with the exception of this Bluetooth issue. I have the Bluetooth paired in the car, and a set of headphones - music and everything worked perfectly on the GNex through the Bluetooth. Now, primarily, it's often choppy (mustic anyway) - for reference, when listening to music I listen via Google Play (all access or whatever they call it now). I figured the choppiness was related to the fact that the music was being streamed since most wasn't downloaded yet, but after very limited experimenting, I believe it must have to do with the physical Bluetooth radio. I had noticed in the past that when the music streams perfectly, a lot of times if I pick it up to check an email, text, etc., it becomes choppy, but thought that was strange since the RAM should be more than sufficient to multitask without choppiness. On my way home from a friend's, I played around and stuck my hand over various parts of the back of the phone, and would press the phone against my pant, etc., and could effectively interfere completely with the connection such that it would be only silent, and not even choppy. Yet, while the music wasn't playing, the track continued to playback on the device and when the music would pick up after I moved the phone, it would be 10 seconds or whatever later as if it had been playing straight through the whole time.
I haven't tested this theory too much yet, but I think combined with your issue, there's certainly something there. Unfortunately, I frequent these parts in order to find answers to these types of issues and don't have the solutions myself.
Do we have lemons, or is this issue prevalent?
I'm happy to provide more info to anyone that can help.
Thanks in advance!
Guys user: BIOYAM
Found a fix that worked for him and for me. You can try this:
Install SetCPU (I used a free app No-frills Cpu controll) with Governor: Interactive, CPU: Max 2265MHZ & Min 652
This totally stopped my bluetooth audio issues. Of course you need to be rooted to use these tools.
Hope this helps. :good:
Just an update for all y'all... My brother has the same phone and he's sort of oblivious to these types of issues, so I didn't trust his take on whether he was having the same problem. Anyway, I tested his phone on my BT devices and his phone had no issue whatsoever, even though mine did as I flipped back and forth between a pairing of the two.
Long story short, I called Verizon who connected me through Motorola and they're shipping me a new one, though they required me to put a $500 hold on my cc until I send this POS one back.
Happy Holidays
Yes
I would be happy for suggestions. My bluetooth headphone keeps losing connection to the phone, and then reconnecting. Now, this only happens when I'm not listening, but since I tend to keep the headphones around my neck when I've paused playback I hear the reconnection beeping, it's annoying. When I resume listening the headphone may, or may not be connected.
I've made sure all the other bluetooth devices have bluetooth off, so I don't think the phones are trying to connect to something else. I read in another post that someone thought they might be having trouble because their car bluetooth was always on. I don't know if mine is, but I can tell you it's a pain to connect the phone to the car. Every time I do I need to go through several menus and, of course, this can only be done in Park, so I doubt the car is trying to take over the phone's bluetooth. :fingers-crossed:
Thanks
Since the MM upgrade, my phone has stopped connecting to my BT headphones automatically when I turn the headphones on. I have to manually connect them, by selecting them out of the list of paired devices. Is this just a change in how MM handles BT?
My issues with BT happen with both Lollipop & MM. My Turbo will randomly turn off BT and when I go to turn it back on I see the BT icon flash a couple of times quickly but it never turns back on. I found a remedy for the issues by using an app called Bluetooth Auto Connect but even with that I still have the issues now.
The phone also turns BT on by itself, even after I have manually disabled it
I'm sure the phone knows that it's going to be replaced with a Pixel and is messing with me as much as possible until then.
Any ideas?
