Currently have the same issue, happens if it is turned off. Will not turn back on unless rebooted

I experience the same problem, Nexus 4, version 4.2.1

I have just come across this issue too.

Me too. I have been able to toggle BT repeatable since I got the phone a week ago, up until just now, had to boot to make it work again.
After booting, it allows me to toggle it again.
nexus 4 Android 4.2.1

Same here on the nexus4

I have the same issue on Nexus 4 after about 2-4 days

Same problem multiple times on my nexus 4.

Same here.

Got this on both mine and my wife's Nexus 4.

Just to give a bit more detail, both my wife and I set up google wallet also. Whenever this condition occurs (bluetooth refusing to turn on), google wallet/bluetooth will drain battery rapidly, causing battery drain of around 8%/hr when idle instead of the normal 3-4%/hr.

Same problem on Nexus 4, works only once after reboot and then can't turn on.

It's a software issue... My wife on the galaxy nexus has the same problem.

Same issue here also. I realized it a couple if weeks ago but now the situation has occurred more than three times. Bluetooth only works when I restart the phone. It looks like  this happens if I do not restart my phone for more than two to three days. Jeff.

My nexus 4 is having similar problems as well. I tried restarting and resetting, neither fixed the problem! This is quite irritating!

Same problem on my nexus 4. Restart is the only solution I've found...

same here with my Nexus 4 and Android 4.2.1 running.
It turned BT on, maybe connected to my navigation system, turned it off and then when turning BT on again it almost immediatly switches off again.
only solution is a reboot... this is not something i would like to have paid for.

Same issue here:  Nexus 4, Android 4.2.1.  Noticed it on the second day after the update was pushed out.  No power-conserving apps installed, and no other radios were on at the time -- no GPS, no WiFi, no NFC.  Sounds like a defect with Bluetooth.  Only way to fix is to restart.  I've had to do this twice now.

sigh, another BT/wireless problem on the N4.

N4 running 4.2.1.  For whatevver reason BT't turn on in the settings, if I flip the switch to the "on" position it immediately goes back to Off.

rebooting the phone fixed the problem. it's not acceptable to have to reboot my cell phone all the time.

I bought all Nexus devices since the Nexus One, but the N7 and N4 are turning into a disaster. I have lost faith in Google's ability to deliver a product and actually follow thorugh to support it.

Same issue but I noticed it after flipping airplane mode on then off. After that Bluetooth won't come back on until reboot. Please fix.

same problem, BT won't turn on in settings or Power Control widget until I reboot.

Same issue here. Seems random but will check if aeroplane mode or disabling Bluetooth trigger the issue. Reboot certainly fixes it.

Add me to the chorus. I have the same experience as above. On 4.2.1, bluetooth arbitrarily refuses to turn on until after a full reboot.

Same issue attached bug report

My problem with the instantanly turning off bluetooth got fixed as it seems.
The problem started after the update to 4.2.1 as it seems. The hotline asked my to make a factory reset. I did this and after reinstalling everthing as before it works like a charm. No reboot necessary at all.
And the runtime until the next recharge is suberb now (2 days it no problem at all).

I have this issue too. Can't figure out how to reproduce it. Only fix is to reboot.

Same here very annoying.
It happens on my brand new nexus 4
Stock unrooted and freshly installed.

Nexus 4 running 4.2.2 (Build JDQ39)
Typically can not switch on bluetooth after airplane mode enabled then disabled. Phone needs to be rebooted to re-enable BT.

Me too have the same problem on my Nexus 4 running 4.2.2. Google please fix this.

Android 4.2.2 and still having this issue. Google fix it, I thought it was because oft airplanemode but then I decided to dont use airplanemode over night and after 3 days had the same issue: Bluetooth stucks in turning on process and stays greyd out

nothing else to say. just fix it.

Same problem here (Nexus 4 with Build JDQ39). After a while Bluetooth cannot be started. When rebooting the phone comes up with bluetooth enabled.

Same issue here. Unknown cause. I never use airplane mode, and disabled all apps, widgets, profiles, etc... which might manipulate bluetooth. Still happens.

Nexus 4.
Stock 4.2.2
Build JDQ39

Bluetooth issue is linked to WIFI.  They just don't work together.  Turn WIFI off, bluetooth works great, but then WIFI fails to reconnect to AP and vice versa.  Other sites claim this is a driver issue.  

I have definitely had this happen, even when WiFi is already turned off.

It has happened to me three times since I had my Nexus 4 (1 month). It "fixes" when it is rebooted (and then BT appears as already on). Turning airplane mode on and off does not work.

4.2.2 JDQ39

[Comment deleted]

Same issue here with using 4.2.2 JDQ39

Same here. Rebooting doesn't seem to fix it for me. This sucks.

Even though this does not seem like a hardware issue; I went ahead and got an RMA. I am testing the replacement unit right now. Will post back any finding, good or bad.
So far I tested Airplane mode on/off and Bluetooth still working afterward. Will post back more findings.

Same issue. airplane mode...no BT....reboot... BT works.

No response from google.  I think we need to get some media involved to cover this.  

Please post a comment to endadget here: http://www.engadget.com/about/tips

I have the same issue on my N4 4.2.2

Same issue on 4.2.2, have to reboot

Same issue on my Nexus 4 on 4.2.2 (already had this problem since 4.2.1).

When I boot it, I can connect my Audi MMI handsfree and use it, after I disconnect and turn bluetooth off, I have to reboot the phone to successfully enable BT again...

RMA unit testing day 2, no bluetooth turning off. I was able to go in and out of Airplane mode and bluetooth still working.
This could be the same effect of factory reset. But we will see.

Same thing here with 4.2.2. Was hoping that they would have fixed it with the update. They must know about it as enough owners have experienced this bug/fault.

I also sometimes get an unresponsive screen and none of the presses register. Was hoping that would have been fixed by the update as well.

I've had this since I've received my N4 last December.
Can the Android team please address this.

4.2.2 Stock.

Seems to occur after an extended period of time with bluetooth on, has occurred post update to 4.2.2 when using a Pebble

Same issue here - starting to get really annoyed with this, its been going on for months.

Just been onto Google support demanding a response to this and whether it a hardware or software issue. They told me it's the first they'd heard about it and I raised the point that how could they possibly not know about it given the number of warranty returns for this and given that I'll be on my 4th nexus from them.

Regarding my posts #44, #50. Here is my update for testing with a RMA unit. Finally after 145 hours of uptime, I tested the Bluetooth on my RMA unit:
1/ Did a test file transfer to my laptop. Success.
2/ Putting it into the airplane mode briefly and then turn off airplane mode.
3/ After that the Bluetooth remained "OFF" and there is no way to turn it back on. The indicator shows the Bluetooth is OFF before going to step 4.
4/ A power off, power on sequence will turn the Bluetooth back to ON automatically. This leads me to believe that the saved state of the Bluetooth was not touched, otherwise the after power on, the Bluetooth should have been OFF.

I draw from this test:
1/ RMA or factory reset won't help resolve the problem. These are just put the phone into a condition where it take longer to exhibit the problem.
2/ Power restart will take your device back to working Bluetooth condition. This is not a desirable remedy.

I think we all should let the press and Android team aware of this problem to bump up the priority.
Cheers,

Same issue with 4.2.2, stock. This should have been fixed already.

Same for me on my N4 4.2.2

They REALLY need to fix this. Tired of waiting!

Same on mine! N4 4.2.2

Reboot seems to be the only fix for N4 with 4.2.2

I have the same problem with two N4 phones. One is 4.2 and the other is 4.2.2.

Same issue with my Nexus 4 on both 4.2.1 and 4.2.2

Same issue with my Nexus 4 on 4.2.2

Yes I do have this issue. Pls try to fix this asap

Same problem on my nexus 4 (4.2.2 build #JDQ39). Restart is the only solution I've found...

Google replied to my email asking if it was a known hardware fault or know software fault. You'll notice they completely avoid answering the question about known software fault......see below.

"I do understand your situation. What I do here is troubleshoot the faulty devices. I understand your Nexus 4 has a Bluetooth issue. If none of the steps we provided was a success, our next step would be to issue a Warrant Replacement.

I assure you for the Nexus 4, the Bluetooth is not known for any hardware manufacturing fault. It could've been your device itself. When your Nexus updated, something could of not updated properly.

If you would like, please reply to let me know if you are wanting a Warranty Replacement."

I've have now written to "The Register" about this and provided the links to the numerous threads on this fault

Same issue with my Nexus 4 on 4.2.2

I also have this issue with nexus 4, android 4.2.2.
Bluetooth sometimes becomes unresponsive and only a reboot fixes it. It mostly happens in the morning, and (I THINK) it happens more often, if airplanemode was activated over night...
If this doesn't get fixed soon (suffering this issue since December with android 4.2.1) I will sell this phone

I too am facing the same issue. Nexus 4 - android 4.2.2

Such a basic feature is supposed to work flawlessly on and advanced phone like nexus 4!

Same here, with 4.1 AND 4.2

My problem is the headset disconnects in the middle of a call, but I can reconnect by opening the bluetooth controls. This headset previously worked flawlessly on an HTC One and an iPhone 4s

I am having this issue as well! The Bluetooth sometimes cannot be turned on unless the phone is rebooted. Also sometimes it disconnects and reconnects by itself even in the middle of Bluetooth music streaming. Is this a HW or SW issue?

I forgot to mention that I'm running 4.2.2

Same for me. It seems like Bluetooth might have already been on just the phone doesn't know it because when I restart Bluetooth is on.

Apparently turning off nfc solves the issue

>Apparently turning off nfc solves the issue

Do you have more info/proof that it does?
I'll turn NFC off in my phone (have yet to ever use it anyway) and will report if I see a difference. I encourage others on this thread to do the same.
I'm running 4.2.2 but it would be interesting to see if this has the same effect on 4.2.1

Was thinking that this was fixed but it's still here, at least on my nexus 4 4.2.2, but it seems like fixed on my Galaxy nexus

Disabling NFC does not solve the problem. Mine has been off since flashing 4.2.2.

>Apparently turning off nfc solves the issue

I will try this also but this still is not a fix, just another workaround.  Currently I use the "workaround" of just not turning off bluetooth.  Google needs to address this problem though rather then pretending there isn't one.

Please spread this bug report link to Android bloggers, press, hopefully to bring this bug priority to higher than "Medium"

I also leave Bluetooth on to avoid the issue. Unfortunately, I also run into the problem of the Nexus simply refusing to pair nearly every time I try to connect it to a device, even two devices that work fine with my Galaxy Nexus. Since I can't turn Bluetooth off and back on (a reboot lets me connect) I've found that power cycling the device I'm trying to pair with works and is faster. Utterly insane that I have to do this nearly every time just to pair a device.

I can confirm that turning off NFC did *not* fix the problem for me.
N4 running 4.2.2

Didn't fix it for me

Turning off NFC does NOT fix the fault.

very annoying bug, pleas increase priority

[Comment deleted]

Same annoying thing happening to me on Nexus 4 + rooted 4.2.2 stock.
The issue is real, and BigG should not pretend it isn't a thing.

-Turned off NFC and Developer Options, then restart the phone. I've been two days without problems. It worked for me

This continues to happen to me too on a Nexus 4 with 4.2.2 stock.

Continues to happen on Nexus 4 running 4.2.2
Related bug: https://code.google.com/p/android/issues/detail?id=39688

Me too having similar issues when toggling the Airplane Mode ON and OFF.
To Workaround, now I turn OFF bluetooth before turning ON Airplane Mode.
Then, turn OFF Airplane mode and then turn ON bluetooth. It worked for me multiple times. To live with until it does get fixed though.. :(

Am having the same problem with my nexus 4. Bluetooth will only work after a reboot.

I have the same issue and only works after rebooting. :(

+ 1. Same problem on my N4.

Same issue.  

[Comment deleted]

same here! almost every time i try to turn on BT it does not turn on!

I've tried this with NFC off and it doesnt seem to make any difference. Its just broken.

Just noticed this today. Seems to have been resolved by a restart. See how long before this happens again.

Same problem here.

I have same issue

+ 1, same problem.
N4 4.2.2 JDQ39

The same issue.Please fix it

Same problem here. N4 4.2.2. Only rebooting helps. Come on Google, please fix it.

Same issue. Reported to Google and techs tried to blame my headset. Complete refusal to acknowledge problem.

[Comment deleted]

+ 1, same problem.

Same issue even if I never turn blue tooth off. I have to restart the phone in order for the Bluetooth to connect to my car. I have to do this each and every time.
Never had this problem with other devices.
Everything on my phone is stock.

Same here.. very annoying..

Nexus 4 Android 4.2.2.
I switch to airplane mode every night before i go to sleep (I do that to save battery because the network signal at home is very weak). In the morning, i switch back to normal mode and bluetoot does not come on. Even if i try to manually turn it on, the sliding bar just denies to slide, and bluetooth stays off. Only if I reboot, then it's all back to normal...

I just got my nexus 4 and wanted to transfer data from laptop to smartphone, the bluetooth button won't turn on. why?

happens randomly after turning bluetooth off...

Most annoying. I need BT all the time and to have to restart the device every few days is so arghhhhh.

Confirmed same issue here with mine.

same issue here :(

wish this wasn't happening but it is.I use airplane mode at work as I'm surrounded by lead walls and no signals get in. Having to reboot seems an asinine thing to have to do for Bluetooth these days. Has anyone had luck with a new kernal?

I'm having the same issue. Bluetooth will turn on once then refuse to turn on again unless I do a reboot.

Same issue here

The Issue only comes up for me when I have Bluetooth turned off for more than few days.
Its really frustrating having to reboot right before I need to pair my phone up

Bluetooth has been off ever since I got a nexus, it wont turn on. Its been months!! I cant use sixaxis controller app without it :( Anybody know if there is going to be a fix soon??

same issue here, glad its not just me. sad its a reported non-addressed issue :(

So, I called support and reported my Bluetooth not turning on issue. She put me on hold to talk to tech department. When she got back to me she told me that there was no problem with my phone sine i can still use it and that I just have to keep rebooting my phone every time i get that issue. I told her that have own many phones before and I have never have to reboot my phone every few days. I told her that rebooting the phone every 2-3 days is not a fix. It's a work a round that are becoming very annoying. At the end she ended up giving me an RMA.
So, after receiving my RMA after 3 days of use it happened again. This time i did not install any apps and left it all stock.
Google please get a fix for this ASAP

Same issue. In addition, I got three replacement of Google nexus 4 in one month but can't get a phone which doesn't have this issue. Sad but it's true. I don't use Bluetooth often but still it's a bad thing for this type of phone and company. Hope it will work

Same issue here

Something I'm trying to make it less annoying: if you have Tasker, program it to turn Bluetooth on and off a few times a day for a few seconds. So far it's working for me, but will report again after a few e extra days.

#127, all you need is to put the phone into airplane mode and back a few times, then the problem will show up. I don't know why it take so long for Google and/or LG to fix this problem.

Same issue with nexus 4.
I'll try the airplane workaround instead the reboot

Experiencing the same problem since I got the N4 in January.  Rebooting "fixes" it for a day or two and then it's back to the same problem - can't turn on bluetooth.  What's up with "Apple" treatment of your customers, Google?

In my particular case (4.2.2, bluetooth switch won't set to on):

dmesg shows:

Well done Google.

Been following these threads (there are about 30 on this bug tracker, tracking similar BT issues) for about 8 weeks now and I keep seeing the same trends:

Google won't take responsibility for the fault. One developer implies it will be fixed in Key Lime Pie.

Now, I would happily wait 6 months for that to happen, perhaps even plumping for an N5, but judging by Googles complete inability to recognise, communicate and fix the issue, I've just ordered a Galaxy S3 for £20 more than an N4. Google have simply failed to instil faith in their competence at fixing this and this is seen among other users on these threads.

So congratulations Google. Your incompetence is now not only losing existing customers, but also potential new ones. Which is a shame because the N4 seems like a great piece of kit, save for this one minor bug (I played on a friends N4).

I'll be unsubscribing from all trackers soon. Come Thursday, I just won't give a shit about the Nexus as a brand anymore.

For reference, I have borrowed an old HTC Wildfire (after my Nokia E5 gave up) and now want to give the phone back and get something a bit quicker. N4 was in the spotlight, but now I've voted with my wallet. 8 weeks is frankly, long enough and in fact, this issue has gone on MUCH longer than this.

I'm not advocating others jump the Nexus ship. Google may well get their act together. But for me personally, I'll be moving into a job role soon where reliability of features on a phone is more important than anything else.

Same issue on nexus 4 for 4.2.2. BlueTooth is not turning on

Same issue, very frustrating.

Same issue. I ordered my Nexus on day one. Received and I saw the problem within a few days. I ordered a replacement, and I got the same problem! I know other people with Nexus 4s and they are not seeing the issue. Could this be a software problem? I don't any weird apps installed or anything like that. Has anybody had luck with ordering a replacement?

Same issue.

Same issue.

Same issue, I'm in Italy with a n4 imported from great Britain (here it's not sold).
Don't want to flame, but Google's silence about this issue is kinda disappointing, I bought this particular device specifically for software support...

Same issue. Very inconvenient when using handsfree systems in a car.

I've been having this issue fairly consistently, 100% of the time. Until yesterday, when I noticed that after toggling airplane mode on and back off Bluetooth was still working. Since then I've been able to toggle Bluetooth on and off without any problems.

The only thing I did yesterday that might have affected Bluetooth was I messed around with my Nexus Q a bunch, trying to set it up at my shop. I hadn't touched it in months and I was having trouble setting it up so in the process, I deleted the Nexus Q app data, uninstalled and reinstalled it, etc. I have a hard time believing everybody here has the Nexus Q app installed but that's all I can think of...

I am running on stock 4.2.2, the latest version of JB, but I am facing a similar issue with bluetooth. my issue is not limited only to the car BT connectivity but also my MW 600 BT headset. It shows that Bluetooth is connected, but I am unable to hear the other person, i go back to handset and switch to bluetooth it works for sometime, only to repeat again. i have tried everything including only enabling phone audio, restarting the phone as well as unpair and pair the device, but to no effect. the issue continues. incidentally, my nexus is 2 months old and on the same version. the issue started around 2-3 weeks back, since then i am facing this and it is a huge problem

Same issue...

Same here - bought an expensive set of bluetooth earplugs (Jaybird Bluebuds X), only to find out that bluetooth on the Nexus 4 can't be turned on half the time. Whenever I turn bluetooth off (to save power), I have to reboot my phone in order to be able to turn it back on.

Same problem da da da da ... my ifanboy friend laughing like hyenas now. Damn you google.

This thread is uber long, and I feel silly saying it, but I'm also experiencing the same issue. I've been dealing with it since December, and I'm shocked that it still hasn't been fixed. I'm a developer. This isn't how bug fixes should be handled...

To clarify... Every couple days, my bluetooth will not turn back on, and a device reboot is required. I don't know what causes it, but this is not acceptable.

Same issue, please do something.

Same problem in my Nexus 4. please fix.

Same issue

Same issue. Google, please fix the radios on your flagship phone.

Same issue on my N4.

Same issue with a brand new Nexus 4, running on 4.2.2.

After reading about the same issue on several forums, with complaints dating a year ago, I find it unacceptable that Google has failed to address the issue so far.

Same issue here with 4.2.2, hope there will be a 4.2.3 soon. I am disappointed about the stability of Android as I have to reboot my phone average every 2 to 3 weeks. With my old Symbian handy I was rebooting about twice a year.

same issue. pls fix it ASAP.

Same BT problem here. Extremely frustrating to have to reboot the phone just to get it to turn Bluetooth on. Please sort ASAP

Seems like everyday someone posts how theirs is not working either. So i am also saying mine doesnt work. when you run an rfkill list i am surprised it doesnt have bluetooth listed. I wonder if the android devices that do work use rfkill?

Same issue, please fix it asap, it is so embarrassing when using my NFC beam! I have to reboot then turn on BT again in order to use it.

Everyone has this issue I assume, attention required!

Same issue here...

Same problem with my Nexus 4 version 4.4.2

I am having the same problem. The Bluetooth will randomly turn off and on.

Same issue with Nexus 4 (302K/rev_11/stock Android 4.2.2).

Same issue here.
Version 4.2.2

Same issue here on Nexus 4 Android 4.2.2

I had this problem on my skyrocket with past M2 snapshot and following nightlies.

I fixed them with the following...

Updating the baseband radio firmware (UCMC1)
Factory reset
Flashed to RC2 of CM10.1

The RC2 candidate had the same issues until I did the baseband update and factory reset.

I've been using LG phone since December last year. It worked OK but all of a sudden, I noticed this problem yesterday.

Still having this issue with a Nexus 4 on 4.2.2. Embarrassing that it hasn't been fixed in nearly 6 months.

having the exact same issue on 4.2.2 stock nexus 4

same issue , bluetooth is not turning on!!!!!!

Same issue. Normally Bluetooth work great, except after my phone comes back from airplane mode. Then I have to reboot to get Bluetooth to switch on.

Same...

[Comment deleted]

Same Issue!
I have Nexus 4 stock rom 4.2.2
I can't pair nexus 4 with any other device (TomTom Rider, Galaxy Nexus, etc...) because bluetooth turn off.
And bluetooth turn off random and it is not possible turn on, only after restart Nexus 4 bluetooth I can turn on bluetooth but there remains the problem of the pair.
This is a serious issue, Bluetooth is not usable! I'm very disappointed and I find it unacceptable that Google has failed to address the issue so far.
Please, solve the issue asap

Same issue. Ready for an S4.  Has there been response on a fix?

Ditto! This issue is driving me nuts! Please google fix this in 4.3!

Same issue. (4.2.2).
And I see that some report that not even RMA helps.
Does anyone know for sure if this is HW or SW related?
Wake up Google!
