Please go back and read the forum rules.

When searching for answers and reading information (especially ones that are as easy to find as the OP's), people gain invaluable information about their issue and device in General. It IS part of the XDA rules to do so for a reason. People should know how to use the search function and be willing to read / research some BEFORE posting in the Q & A section. Q & A is not a substitute for doing so. And, pointing people in the correct direction (giving successful search terms or correct sub forums) allows people to find a lot more information than giving them a short half-answer that is no substitute for the many threads full of information that already exists. Linking people to all-in-one threads or hard to find obscure information is different, but all other cases should use search and read tactics first.
[Nexus 4 Q&A, Help & Troubleshooting] pshaww:
I am subscribed to a few Google group conversations about Bluetooth issues with the Nexus 4 and reading each complaint prompted me to ask. Does anybody out there with a Nexus 4 NOT have an issue with Bluetooth?

I am on my 2nd replacement Nexus from Google Play device support and a third is on the way. If this third device doesn't work, then I either can opt for a refund or wait for Android 4.3 to hopefully fix it, if the problem is software salvageable. So I'm just curious if anybody's N4 actually has no issue with Bluetooth and in what manner do you use Bluetooth and with what devices?
[Nexus 4 Q&A, Help & Troubleshooting] Lewythefly:
I got my N4 in the first batch from play store back in November

I have never had any issue with Bluetooth

Granted I don't use it often (once every couple weeks on average) but each time I have its never failed in any way.

I have used in my car for hands free and also to send pics to my GF's phone and a couple times to transfer files from my laptop

Started out stock and then last few months been on custom ROM's with no change
[Nexus 4 Q&A, Help & Troubleshooting] AdamHart612:
Day 1 N4 here too - never had bt problems. Pairs with my car, Motorola headset, and Moga Pro just fine. Fiancée's stock unrooted N4 pairs with her car and jawbone speakers fine. Hoping 4.3 brings LE bt support for my fitbit flex, but besides that haven't had to do anything but turn on bt and pair.

What problems are you having? Haven't heard of people really having issues...
[Nexus 4 Q&A, Help & Troubleshooting] nascasho:
To my knowledge from researching the problem myself people claim it's a hardware issue based on some of the responses they get back from google I guess? I knew right away it wasn't just me when someone else I know has a N4 as well and when I use my LG Tone with his while connected via WiFI it pulls a dubstep and drops.

Other than that it's the only issue I have with BT that I can replicate. Hands-free while connected via data works like it should.
[Nexus 4 Q&A, Help & Troubleshooting] Rusty!:
No Bluetooth problem here.
[Nexus 4 Q&A, Help & Troubleshooting] daern:
Stock 4.2.2 doesn't work properly with my car (BMW E61 5-series). Basic phone works, but no contact sync due to bugs in the N4 bluetooth stack. Moved to CM10.1 which contains various fixes for this and it's worked perfectly since then.

Honest truth - if the first device didn't work and the second was the same, why on earth would you assume that this was a hardware problem and keep sending the phone back? Either request a refund, switch ROMs or put up with it!
[Nexus 4 Q&A, Help & Troubleshooting] AdamHart612:
Oh sure I guess I have heard people mention that... BT and both 2.4ghz and 5ghz wifi coexist just fine on both N4s here. I just wish it could take advantage of my ac router.

Got my N4 in the second batch of those available and have no issues pairing with my vehicle. I don't use Bluetooth for anything else, though
[Nexus 4 Q&A, Help & Troubleshooting] moe6:
Bluetooth generally works, it only screws up from time to time for things like pairing with a new device. It's been more or less this way since JB and generally if you have a regular bluetooth setup of headset, in-car radio etc, it 9/10 works just fine.

Introduce some complications and it does wonk out sometimes. I've had plenty of times where it wouldn't want to pair right to my laptop or desktop after I factory reset my device. Sometimes it just won't get picked up either when BT is on, visible and another device is looking for it.

I believe I remember reading that there was a legit explanation for this regarding drivers and or some security thing but it's been long enough that I don't remember what the details were or where I even read it on XDA. May have even been the GN forums.
[Nexus 4 Q&A, Help & Troubleshooting] ghostlobster:
I've seen the exact problem indicated by the video on CM 10.1. I just restarted, wiped dalvik and all was well again.

Other than that my BT has been perfect. I use it daily in my car for audio streaming and phone. At home I pair it to my PC for audio streaming and it works perfectly.
[Nexus 4 Q&A, Help & Troubleshooting] crowboats:
I actually haven't run into many issues with Bluetooth. I use it mainly with Jawbones Jambox and it pairs up just fine. I think it may have dropped connection a couple times but less than a handful. I do run into problems when I miss a call from someone though. The audio quits playback though the devices remain paired.
[Nexus 4 Q&A, Help & Troubleshooting] michaelg1030:
I guess I have issues. I leave BT on all the time and only randomly does it automatically connect when I get in my car. I generally have to go in to the BT settings and click the device to pair with. It identifies the device, but doesn't connect automatically.

On stock 4.2.2, I had issues with BT not connecting at all and it would get stuck in an on/off post ion (it would never fully turn off or turn on when I toggled the switch). I would have to reboot to get it to work. I have yet to see this happen on cm10.1, I just have the automatic connect issue with cm10.1
[Nexus 4 Q&A, Help & Troubleshooting] flintdragon:
I usually have no issues pairing and using. But I definitely have these two issues:

1. BT won't turn on at all (like in the video).

2. I notice my phone hot and draining battery. I look at the BT indicator and it is blue indicating a connection but I'm not connected at all. I only use BT in the car and I'm nowhere near my car. Yet the indicator is blue and my phone is hot.

Either is resolved with a quick reboot. I'm not troubled by it but is annoying at times.
[Nexus 4 Q&A, Help & Troubleshooting] CyberDonky:
A few weeks ago I thought that I also had issues with bluetooth, but it was just the app 'Tasker'. This app was struggling with my system.ui/bluetooth.

November unit. No bluetooth issues. Running stock rom and kernel. I use it around once a week only though
[Nexus 4 Q&A, Help & Troubleshooting] TonyHoyle:
No issues... been working great since JB in fact - the older versions would fail to pair or (most annoying) pair the hands free but not the BT audio, meaning a frustrating round of switching bluetooth on/off until it worked.

Sound quality seems better too, but that's subjective of course.

Stock rom, standard OS (although I do use bluetooth keepalive.. not sure if that's still needed).

If you are having an issue you need to go back to stock. You can't return your phone because of issues when you are not even running what it came with..

Having the same issue with a stock N4. The funny thing is that it happens with a RMA'd N4 from the latest batch - 306K(!)

It doesn't matter if I disable/enable WiFi, it won't allow me to turn BT back on without having the device rebooted.

I think that the drivers are completely faulty in 4.2.2.

I guess I won't disable BT until Google sort it out, hopefuly in 4.3
[Nexus 4 Q&A, Help & Troubleshooting] kmandel:
Two Issues

I'm running stock 4.2.1 bought direct from Google shortly after they became available after the long out of stock. I see two BT problems

1) After a reboot when I pair with an ad2p device the media sound still goes to the internal speaker not the ad2p device. My workaround is to place a phone call and at that point it starts playing through the ad2p device (both media and phone). I can abort the phone call after I hear a ring. This is ok until I reboot.

2) I do a lot of switching between ad2p devices. I have ad2p earphones and a ad2p car radio device. I switch when I go in or out of the car. The main issue is that after several switches the phone goes to black screen unresponsive and I have to force a reboot (which plays into 1)). Also from time to time it just doesn't want to pair with the live device. (I'm careful to switch one off before turning the other on)

Do you think there could be a hardware issue addressed under warranty?

Do you think these issues are addressed in 4.2.2?

I don't really want to go to 4.2.2 just now because of LTE. LTE works nicely on my stock 4.2.1, and my BT issues precede any LTE availability. I know there are LTE workarounds for 4.2.2 but I figure that 4.3 is coming soon and I'l wait for it and just deal with whatever its LTE issues are.

I've never had any problems with Bluetooth on my N4 until I was updated to 4.3. Now Bluetooth is a nightmare. My BT headset works fine but my BT keyboard has stopped working properly and my BT OBD2 car ECU adapter has stopped talking to my ECU (still works on my wife's N4 on 4.2.2) - both were fine when I was on 4.2.2, both with and without WiFi.

Same here... if there was something wrong i would have found it because BT is a MUST for me and it is usually the first thing i test when i install ANY version of android
[Nexus 4 Q&A, Help & Troubleshooting] kmandel:
This could easily be the problem on 4.2.1 I was seeing where after switching between car bt and headphone bt several times the phones goes black until a reboot.

I just updated to 4.2.2 since that seems to be the easy way to get to 4.3, and the hybrid radio seems to address the LTE issues. I'll probably stay at 4.2.2 for a few days just to see if the BT hang is gone, before venturing to 4.3.
[Nexus 4 Q&A, Help & Troubleshooting] JTHM:
Guys,

I too don't have any problem listening to music and making calls through BT. It's when I try to do something a little more obscure (/less tested for) where the problems I'm struggling with are arising. If all you do is listen to music through BT then you're probably not going to see any issues at all.

As I said above, my wife's N4 on 4.2.2 doesn't have any problems and neither did my N4 until I got updated to 4.3.
[Xperia Z Q&A, Help & Troubleshooting] Stephen_wolf:
Hello there,

I was running the latest android 4.2.2 on my device when I installed the current version of CyanogenMod for the Xperia Z. Since using the mod, my NFC no longer works, which it did previously. I tick the box, it stays grey and then unchecks itself. I have tried 2 fixes to no avail, both "NFCfix" and "possible nfc fix).

Is this a commonly known issue and is there a fix? Many thanks. Stephen.

PHONE: I9100TDVLS3

Android Version: 4.1.2

Kernel Version: 3.0.301-889696 dpi@DELL168#3

Build Number: JZO54K.I9100TDVLSM

I'm having trouble working out what files I need to root my phone as there are so many variations, I don't plan on installing a custom rom I just want superuser access. There does not seem to be the correct kernel version for my phone in this post. http://xdaforums.com/showthread.php?t=1101671

The closest one I think would be GT-I9100T_DUKF2_insecure is that correct as I don't want to brick my phone if there is a chance using the wrong kernel as I don't have a spare one to use until I get it fixed. I have seen people suggest using I9100 instead and flash the modem but I don't want to do that or is this the only way?. I would have posted this in the kernel topic but I don't have the user permission to do so.

I will be using this guide http://reviews.cnet.co.uk/mobile-phones/how-to-root-your-samsung-galaxy-s2-50004972/

Aside from the rom manager https://play.google.com/store/apps/...EwMiwiY29tLmtvdXNoaWtkdXR0YS5yb21tYW5hZ2VyIl0. Are there any other recommended apps that need to be installed after the rooting process
[Galaxy S II Q&A, Help & Troubleshooting] Hopper8:

I've got another one:-

If you can't work out how to root this phone without making a thread in Q&A given it was released two years ago, I'd question whether you should be messing with your phone in the first place. Read some threads (which people attempt to circumvent by posting threads like this; refer to my sig as to what happens to these people), settle on a method. It's not rocket surgery.

Edit - And another - If you're scared of bricking your phone, just don't go there. The moment you root your phone, kiss goodbye any expectation of warranty service.

[Sony Xperia ZL] Dr_SUSE:
Hello,

I recently tried to update my Xperia ZL L35H (purchased in China) to the latest 10.3.A.0.423 firmware. I chose the C6502 variant because it seemed that this was the same model with some regional variations. All worked well, until I tested the mobile data connection, which was non-existent. Considering that both L35H and C6502 both use HSPA, this incompatibility with the C6502 firmware was surprising. I even used the AOKP ROM for awhile and had no issues with data connectivity.

What's worse, I had my CWM backups on internal storage. My bad, I know. Updating to the 10.3.A.0.423 erased my internal storage, so, no more stock firmware backups.

I would be most grateful if some one could help me either:

*Help me find a L35H firmware, or

*Help me troubleshoot the data connection on the C6502 10.3.A.0.423 firmware.
[Sony Xperia ZL] Thorc:
L35h

Glad to see someone else has the L35h. I'm afraid I can't help you with your problem, but I was wondering if you were able to root it, and how?

I rooted mine with Bin4ry's script, but then made the mistake of upgrading, not knowing that it would remove the root. (I'm completely new to Android and had no idea that the phone would come with a bastardized version of Android that doesn't even allow a Google account to be on it, without rooting.) Now I'm on 10.1.1.A.1.253, but none of the rooting scripts will root it now.
