Bluetooth toggle doesn't work all the time?

The past few weeks I have been experiencing the bluetooth toggle both widget and settings not working unless I reset my phone. Any ideas why it's acting like this? I doubt it's a hardware issue. Any help would be great. Thanks!

i have / had the same issue, but lately has not happened. I am on the franco kernel r29. give that a try and see if you still cannot enabled bluetooth.

I had the same problem today. It was stuck on "off" until I rebooted my device.

I had this happen once. I am stock. Rebooted and it was fine.

I reboot when it happens also, but then it happens a few days after. I'm not sure why it does that. Maybe a bug?
Sent from my Nexus 4 using xda app-developers app

I can't turn on my wifi and bluetooth neither. First I can turn them on after reboot, 2 days later, reboot doesn't work. Maybe it is a bug.

Okay well at least someone else is having the same issue as me, I hope it just a bug also.

do you have an NFC tasker installed? I think that might cause the problem...no sure tho, I'm having trouble with bluetooth not turning on too.

My 2 nexus is having the bluetooth issue, it will work when reboot or restart, but after a couple of day, you cannot switch the bluetooth on until you restart it. One nexus is rooted stock with bunch of app, The other is bone stock with very few app install.

This is partly true. It could be a compatibility issue. What year and model is the car?
What ROM/kernel are you using?
Sent from my Nexus 7 using Tapatalk 2

Blutooth is broken on 4.2.1 you need to wait for 4.2.2 or use a custom kernel like Franco's Kernel.

Mine connects to my 2012 Ram on unrooted stock 4.2.1 with no problem. OP, see if there is an update for your vehicle from the dealer. My '12 has already had one due to an issue with the HDD in the radio.

Just called and nothing. They actually have never heard of anyone trying to pair their tablets. I had a feeling they would not be much help.
I am wondering if I try to go to another rom.

You're on 4.2.1 stock?
Wouldn't hurt to try. I'll try connecting to my 2013 Jetta tonight. What is it you're trying to tether? Audio, I suspect...

Cars usually only connect to Phones via bluetooth because phones have different bluetooth profiles than tablets since phones have changes in their framework to allow phone calls.
most cars connect to the phone so you can use the phone hands free. tablets dont have hands free bluetooth profiles thus is probably why your Mercedes isn't linking properly as the tablet doesn't support syncing phone books and phone calls.
Someone else may have paired theirs with their Dodge ram but they most likely paired it for Audio to their audio system but not their navigation/phone system.

I got the same problem next time will buy a BMW.

I had issues connecting an android 4.2.1 device to an AUDI A6. gave up after a few days, even took it to the dealership and they couldn't figure it out.
for some odd ball reason, android bluetooth just doesn't work right. I tried all my apple devices (ipad and ipod touch 4g) and it connected instamagically to the car.

Let me know how it goes for you and I will try the later rom

Nexus 4 aokp sound not working

Hey so I've been running aokp for a few days now, and suddenly I noticed that the sound isn't working, not for notifications, not for music, videos, anything. Not even when the headset is plugged in. So I flashed my stock Rom backup and it still isn't working, any ideas?? Thanks!
Sent from my Nexus 4 using xda app-developers app

Ok this is weird, sound just started working on my stock Rom. Haven't tried aokp yet, the restore backup of stock Rom took 30 minutes and I need to sleep soon so I don't want to risk hanging to stay awake for it, it normally takes 3 minutes to restore backups though, idk what's wrong

I'm having a pretty same problem here, the only difference is that I'm running Paranoid Android on my Nexus 4. Do you find any solution yet?

[Q] my nexus 4 bluetooth ruins the wifi (drops)

So, when I turn on the bluetooth and connect it to anything, like headset or stereos, speakers, there is some wifi drops every 10 seconds or less which is so annoying, cant watch a youtube video or browse easy and everything is ruined, so how to fix that? And is that only me? Im rooting my phone next week, cause that was a replacement and on my old nexus 4 never used bluetooth after 7 months , so dunno if i had that on my old nexus 4 or not.

I have the same issue, when you use Bluetooth it interferes the 2.4GHz radio waves created via WiFi chip, 5GHz works fine on WiFi with Bluetooth on.

Sorry im not good at these hardware stuff, but how can i change it? Is it in the router settings or inside the phone, thanks!

Unfortunately that is where the problem comes in, I am not sure if it is hardware or software which is causing the issue.
If you want to keep connection on WiFi with Bluetooth then for now you have to use a Wireless Router which supports 5GHz (to enable support on Nexus 4 go to settings, WiFi, advanced and then Wi-Fi frequency band which will show up a list, choose "Auto" for 5GHz and 2.4GHz).

It's not fixed when I receive a call in my car the n4 drops wifi. And that was the main reason for getting a wifi router in my car. I'm on 4.3 My galaxy Nexus does not have that problem. This needs to be fixed soon.

I dunno, its fixed since i flashed the 4.3 paranoid android rom, and google support sent an email saying that its fixed in android 4.3 and they said that cause i called them several times because of that issue, Ive never had this issue on my gnex, but I had the gnex when it was on 4.1.2, i heard that its a bug in 4.2.

[Q] nexus 4 locking up during chromecast

I've noticed my nexus 4 completely locking up during chromecast control being active. It especially likes to happen after locking the screen. I'm on 4.3. Anyone else having this issue? It never locked up before and doesn't seem to unless I'm actively controlling my chromecast.

Did you get 4.3 OTA or did you flash it?

Were you trying to stream with Netflix?

Flashed it. And it does it for Netflix and YouTube and gmusic. All I've tried.

No problems so far with 4.2.2. I'll try and remember to post back when the 4.3 OTA hits.

It happens to me too

Me too.

I am having the same issue. When I am Chromecasting, the phone will not wake and I have to hold power to reset, luckily this does not affect the stream. I also flashed 4.3 and did not wait for the OTA.
PS. I picked mine up from Best Buy also. I had to call around and find one that just had it delivered as they are going FAST. I know that a few of the other Best Buy's around me are getting a few shipments in over the weekend.

I flashed mine but I used the factory image, there shouldn't be any difference between the factory image and the ota..... Right?

Dunno, it seems everyone having issues flashed 4.3, but I have yet to see a post from someone with an OTA update.
4.3 is supposed to have new DRM in it. Perhaps it doesn't get along well with root.

Yeah, root was my very uneducated guess
Sent from my Nexus 4 using XDA Premium HD app

I do not think that it has anything to do with root. I sideloaded with locked bootloader and not rooted and am currently not rooted. But then again I could have messed up somewhere.

I'm having the same issue with Netflix and YouTube on my Nexus 4 (haven't tried Google Music). I'm non-rooted, completely stock 4.3. I got my update OTA.
My wife's Nexus 7 (stock, unrooted 4.3 via/ OTA) has no issues.
