[Nexus 6 Q&A, Help & Troubleshooting] MVLJR:
Hello everyone,

I'm having major issues with my Nexus 6 over the past 3 weeks or so.

I've had this phone for almost 2 full years now and love it, however, over the past 3 weeks the bluetooth function keeps turning off when I reboot my phone every night.

It NEVER did this in the past 2 years. Only the last 3 weeks. It seems to be some sort of battery saving feature, I would presume.

What drives me nuts, is I always like to have my bluetooth on, since I get in my truck and it auto connects to my GMC IntelliLink (which is also a problem).

So does anyone know why, all of a sudden, after reboot, bluetooth defaults to off and I have to manually turn it on every time? My Nexus 6 has been flawless up until now.

I've looked everywhere for an "auto start" option for bluetooth, but cannot find one. I have ZERO idea how this happened all of a sudden. I've been running the same ROM since last February with no problems (ROM screenshot attached).

As for my bluetooth truck problem, that started today. All of a sudden "phone audio" will not let me select the box, only "Media Audio" and "Contact Sharing" boxes are selected. Thus my Pandora plays over bluetooth, but my phone calls will not.

Also my Bose Quiet Comfort headphones used to connect perfectly with my Nexus 6, now I'm at work and I notice if I turn the headphones off, then come back and turn on, it'll say "connected to Nexus 6", but the sound is playing through the phone instead of the headphones, even though the bluetooth connection has been established.

Again, this is only over the last few weeks.

Any help would be greatly appreciated.

I'm willing to update to a new ROM or do a wipe, I just tend to live by the motto "if it ain't broke, don't fix it"........ except now it is broke and I want to fix it.

Thank you-

Paste a logcat here. A dev could take a look and help you out.

or

Backup your stuff and do a clean install of a new pure nexus or whatever rom, if it's still present after that, maybe it's just your battery starts to dying after 2 years.

Edit: I'm using crdroid as daily driver and have no bt issues
[Nexus 6 Q&A, Help & Troubleshooting] Fvolfrine:
So glad you posted this, I'm having the same issue! After either a restart or just a period of time my Bluetooth turns to disabled. It is especially frustrating as I have it connected to my watch, which allows me to unlock with smart unlock. When the Bluetooth is disabled, I have to punch my pin in.

I am on stock 7.1.1, February update. I am rooted and flashed the Echo Permissions Fix. I was going to flash stock again this morning, but decided to check here first for a solution. I am just happy to know that it's not just me.

That being said, like [MENTION=1204871]MVLJR[/MENTION], I recently flashed PureNexus ROM and that for me is when this began. I flashed back to stock via flashall, but it has not stopped the problem. Could it be a PureNexus thing?
[Nexus 6 Q&A, Help & Troubleshooting] Fvolfrine:
As we have PureNexus somewhat in common, I am doing some searching on that page. I had previously posted there about it, but I don't think I ever got a response. Someone mentions it on Page 3417, I'll keep reading to see if I find a solution.

My post, by the way, is on page 3420.
[Nexus 6 Q&A, Help & Troubleshooting] muiriddin:
I had a problem like this on Pure Nexus and flashed back to stock (N6F26R) to see if the problem goes away...

Previously on stock (release before N6F26R) and never had an issue. I use Bluetooth with a watch, fitness band and sometimes my Wife's Ford...
[Nexus 6 Q&A, Help & Troubleshooting] Fvolfrine:
[MENTION=5143648]muiriddin[/MENTION], did the problem go away for you? Because I flashed back to stock and the problem persists.
[Nexus 6 Q&A, Help & Troubleshooting] Fvolfrine:
[MENTION=1204871]MVLJR[/MENTION], I suspect that the problem is Android Wear 2.0 on our phones. Do you have a smart watch?

Edit: On the PureNexus forum, people without Android Wear are also experiencing it. So back to the drawing board. I still do not think it is your ROM.
[Nexus 6 Q&A, Help & Troubleshooting] Morpherios:
Reading this thread reminded me of something I dealt with a while back, I don't know if this will do it for all of you, but I figured I'd post this. I screenshotted a reddit thread that fixed the problem for me. I can't remember if what I experienced was the same as all of you, and I am not having the problem now. But I hope this helps. Please see the attached screenshot.
[Nexus 6 Q&A, Help & Troubleshooting] MVLJR:
I don't have an android watch, but I do have a fitbit and don't have any problems with it.

A little update, I cleared my Bluetooth cache and changed the name of my device, which seems to have helped.

My Bose headphones now autoconnect like before.

However, my Bluetooth still shuts off after reboot. My GMC Intellilink still won't let me select "Phone Audio" either.

I think I'm going to flash a new ROM this week, which sucks because I've grown attached to the Pure Nexus ROM.

Can someone show me how to post a logcat?

Thanks

This (and similar) bluetooth issues have been reported on the nougat product pages. It's not unique to PureNexus or the Nexus 6.

Reports are that 7.1.2 (beta) fixes the issue on devices that have access to it. Hopefully a fix comes down the pipe for the Nexus 6 as well, as I have some of the same issues.

Similar posts can be found on the nexus6 and googlepixel subreddit pages.
[Nexus 6 Q&A, Help & Troubleshooting] MVLJR:
My question is, what prompted this?

I've had the same ROM for a year, no OTA updates. Had to be an app update, correct?

No other way to explain how it worked for a year, now problems all over the place
[Nexus 6 Q&A, Help & Troubleshooting] larrysteeze:
You've been using the same ROM, but updating the version of the ROM, correct?

And the ROM updates are based on updates made to Android by Google.

So if a bug makes it into Nougat, it will (generally) make it into the modified ROM as well.
[Nexus 6 Q&A, Help & Troubleshooting] MVLJR:
Incorrect, I've been on the same version of Pure Nexus since last February, screen shot in original post
[Nexus 6 Q&A, Help & Troubleshooting] Morpherios:
I take it the fix I posted didn't help? I was really hopeful that it was the same issue and that would fix it up.
[Nexus 6 Q&A, Help & Troubleshooting] MVLJR:
I haven't tried it yet, at work right now, I'll give it a shot later.

I'll update my findings.

Thanks
[Nexus 6 Q&A, Help & Troubleshooting] Morpherios:
Will keep my fingers crossed. One thing to note, when doing that fix, it *will* wipe your bluetooth auto-pair devices. So don't fret if nothing automatically connects afterwards. You have to repair everything.
[Nexus 6 Q&A, Help & Troubleshooting] Pkt_Lnt:
It is not a new problem, there are many threads in the Q&A forum if you search. Here is one:

https://xdaforums.com/nexus-6/help/bluetooth-off-reason-pattern-t3435436

(there are more links and suggested workarounds in that thread from me)

That said, installing the AW 2.0 DP 4 totally solved my BT disconnects from my Huawei watch and LG stereo headset.

The changelog on the latest Huawei AW 1.5 mentions BT issues, but I have not tried it.

AW 2.0 official is supposed to start rolling out OTA tomorrow, so we shall see. (finners crossed tite ;) )

I'm on Jan 21 PN 7.1.1, latest AW app. I have no suggestions of those having issues with no Android Wear, but there are threads here with suggested workarounds that solved this for many of us before, you might want to check them.

[MENTION=6679863]Morpherios[/MENTION] and [MENTION=1204871]MVLJR[/MENTION]

I don't know if it's of any note, but one of the actions I attempted in trying to fix mine was to reset all network settings via the "More" option in Wireless & Networks settings (I backed up wifi settings in advance). That's essentially a nuking of all network settings, including wifi, cell, and bluetooth. It did not resolve my issue.

[MENTION=4403217]Pkt_Lnt[/MENTION] seems to be indicating that with updated AW on his watch, the disconnects are not happening. How the software on the watch (as opposed to the AW app on the phone) would be causing bluetooth to crash, I'm not sure. But it's not outside the realm of possibility.
[Nexus 6 Q&A, Help & Troubleshooting] Pkt_Lnt:
My words were / are different than that:

AW 2.0 DP 4 totally solved my BT disconnects

That means they do NOT happen any more, since Dec 11, 2016 when I installed AW OS 2.0 DP4 was released and I installed it on my watch. Not. One. Disconnect. None. Nada. Zero. Zip. Zilch. Nein.. :victory:

BT devices communicate both directions. The watch CAN control the phone, and was turning off BT. It was obvious when it happened, when my headphones prompt "Out of Range, trying to connect" (I came to hate hate that voice prompt :mad: )

I would immediately open the AW app on the phone at disconnect and was prompted to turn on BT because it was off. :(
[Nexus 6 Q&A, Help & Troubleshooting] larrysteeze:
[MENTION=4403217]Pkt_Lnt[/MENTION] I completely agree that it BT communication is two-way...I stated that it's not outside the realm of possibility because there are a number of factors that could do it, including the phone receiving a message it simply doesn't know what to do with and causing a fault. This could explain my bluetooth share crash messages that I received on occasion.

It's encouraging to know that it's fixed with AW 2.0 for you. I hope it carries through to me when I get the update. If the OTA doesn't drop tomorrow, I may have to flash the DP as well.
[Nexus 6 Q&A, Help & Troubleshooting] Pkt_Lnt:
That OTA will begin roll out tomorrow, but will likely take a few weeks to get to everyone. Many of us in the Huawei watch forums are looking for it to capture the URL and upload it.

I tried to find this file via Astro viewer, but it was not there.

Any other idea where this file can be found?
[Nexus 6 Q&A, Help & Troubleshooting] muiriddin:
It did not, it did happen less often...

Just yesterday I went into settings - location - three dots - scanning and turned off bluetooth scanning. Have not had a reoccurrence after that... Yet...
[Nexus 6 Q&A, Help & Troubleshooting] Fvolfrine:
I flashed back Monday and it still happens every time I reboot. And sometimes Bluetooth just turns off on its own.
[Nexus 6 Q&A, Help & Troubleshooting] muiriddin:
I just rebooted to test and Bluetooth came up and reconnected to my watch... We seem to have slightly different symptoms...
[Nexus 6 Q&A, Help & Troubleshooting] Moguledyouth:
Work Around

As a work around and since I already have and use Tasker, I have it set up that Bluetooth is always on, if it is disabled it will automatically re-enable it.

**Update** so I decided to install the AW 2.0 DP4 on my Huawei watch, and just had my bluetooth disable itself on my phone AND would not re-enable itself and caused a loop in the Tasker task because of it...
[Nexus 6 Q&A, Help & Troubleshooting] larrysteeze:
Thanks for the update.

I'll try flashing it tonight as well. I'm doubting we'll see the OTA for another week or so.
[Nexus 6 Q&A, Help & Troubleshooting] scap99:
I'll join in on the BT issues wagon.

Mine is weird. BT doesn't turn off, but doesn't work until I cycle it off then back on. I get in my truck, it will connect but Pandora will only play music. The song data doesn't display. Also, I can initiate a voice dial with the truck, but the phone won't dial.

After I toggle BT, all works as it should.

I don't own any AW products, and there's only my truck paired to my phone right now.

OP, thanks for starting thread and I hope we find a solution soon.
[Nexus 6 Q&A, Help & Troubleshooting] MVLJR:
Thanks for your input.

My truck does the same thing, except Pandora will connect, but my phone audio refuses to play over bluetooth now, all of a sudden.

This is the most annoying part of all! I can live with having to toggle bluetooth on after a restart, but I cannot live without bluetooth in my truck. I keep forgetting it won't work and have to hit the speaker button on my Nexus 6 instead, major PITA

Flashed the 2-15 Pure Nexus.

So far so good. Truck and phone paired and worked without cycling BT
[Nexus 6 Q&A, Help & Troubleshooting] Moguledyouth:
Day after update... after I made sure that all the app updates were done on DP4 (both android wear and google app needed updating) as well as I believe a new Google (beta) app update last night, I have not had the problem of my bluetooth turning off after a reboot. I am still on the early Jan. PureNexus release.
[Nexus 6 Q&A, Help & Troubleshooting] larrysteeze:
Your post gave me hope.

Unfortunately, I'm still having the issue with the new PN version.

That said, I drove home the last couple days with my watch turned off. Both days, I did not have one bluetooth issue until the watch was turned back on. I'm ready to declare [MENTION=4403217]Pkt_Lnt[/MENTION] correct. I intended to flash DP4 to my watch last night but did not end up having the time to do it.
[Nexus 6 Q&A, Help & Troubleshooting] Moguledyouth:
Just make sure to update all apps (both Google app and Android Wear app had updates) on DP4 once you have it set up, after that it was smooth sailing for me.
[Nexus 6 Q&A, Help & Troubleshooting] scap99:
Since I don't have anything but my truck paired, that does seem to indicate the possibility that we've narrowed this down a bit.

I don't know what would have changed in the background from the 1-21 to 2-15 PN, but I was a late adopter of the 1-21 version since I absolutely hate clean flashing.

Shortly after installing it I noticed the BT starting to get wonky. Not sure if it was coincidence or not, just happy to have eliminated the extra step each time I start my truck.
[Nexus 6 Q&A, Help & Troubleshooting] scap99:
I swear my phone must know I'm talking about it.

Jumped in the truck to go home and it wouldn't pair with my truck.....

BT was off, whiskey tango foxtrot!?!?!

It's like it suddenly got worse.

All I did was root, update my ad away hosts file and install elementalX kernel.

Anyone one else using any of the above and having issues?
[Nexus 6 Q&A, Help & Troubleshooting] scap99:
Had to cycle BT, when I got in the truck this morning.

Pandora was playing, but the song name data wasn't loading on my truck's screen.

After cycling the BT, everything seemed to work as normal.
[Nexus 6 Q&A, Help & Troubleshooting] MVLJR:
Ah here we go again. Major Bluetooth issues, phone audio won't play in my DENALI truck. I know it's not the GMC Intellilink because I paired an iPhone with no problem and audio works.

My Bose QuietComfort headphones also lose their Bluetooth connection!

So damn frustrating, guess I have to do a complete wipe and install a new ROM
[Nexus 6 Q&A, Help & Troubleshooting] scap99:
If you find something that works, please let me know.
[Nexus 6 Q&A, Help & Troubleshooting] stevemw:
Same here. I was on 7.0 (Dec 5. 2016 security patch) and updated the phone app to 8.0 when the problem began. I applied the OTA updates for N6F26Q (Jan) and N6F26R (Feb security patch) but the problem persists. I read somewhere that the 8.0 phone app is the cause of this.

This is a problem for me because my Moto 360 2 gen keeps getting disconnected and I find that Bluetooth is turned off on the phone. To make matters worse I use the Google Authenticator app a lot and it's more convenient to get a code from the watch than picking up the phone.
[Nexus 6 Q&A, Help & Troubleshooting] scap99:
I swear mine has gotten worse this weekend.

Not sure what updated for the worse, but it is frustrating the crap out of me.
[Nexus 6 Q&A, Help & Troubleshooting] MVLJR:
Well great news!

I flashed over to Pure Nexus 7.1.1 -20170215-OFFICIAL, Build NOF26W

And no more bluetooth sync problems. It now works in my GMC truck again.

However, I still have to start bluetooth manually after a restart, but I can live with that for now.

I'm just happy I get bluetooth audio over phone calls in my truck again.

I did a clean install and wiped the cache, dalvik cache and all settings.

This seemed to do the trick.

If anyone has any findings on how to restore bluetooth to always on, I'd appreciate any input.

Thanks
[Nexus 6 Q&A, Help & Troubleshooting] scap99:
I've been on that version of PN since it dropped.

This morning, I had to manually start BT. It connected to my F150, then 30 seconds later turned itself off. It would not restart, at all. So I reflashed PN and wiped caches. Still didn't work. Then I tried force closing and clearing cache and data in the BT share process. Didn't work. Did that again, but added a reboot, and now BT turns on. I won't be back in my truck for a bit, but hopefully this method cleared a gremlin. Otherwise, tonight I'm going to get drastic...
[Nexus 6 Q&A, Help & Troubleshooting] scap99:
20 minutes into my morning drive, BT crashed.

I'm going to do a factory reset and run stock :( to see if it goes away.

This is quickly pushing me to look at other phones....

I flashed the N6F26U factory image and radio a little while ago.

So far so good. I mean it kinda sucks being on stock rom, but I'll take function over form any day.
[Nexus 6 Q&A, Help & Troubleshooting] Axel85:
So there's no Bluetooth bug on march update? I m going crazy,because this bug randomly turns off my Bluetooth, enter the do not disturb mode (I find it's started by wear so should be related) and sometimes when I get a call in car my stereo is connected and I can answer from that, but the audio goes through the phone loudspeaker,and I have to switch it manually to Bluetooth even if connected. Never had those problems on a nexus 5. I m starting to think that android wear makes Bluetooth bug worst... Someone said that had no bug after he updated the smartwatch to wear 2.0, sadly I can't try because mine will not get it.
[Nexus 6 Q&A, Help & Troubleshooting] scap99:

Today after I disabled this setting seems to works good,but I'm not sure
[Nexus 6 Q&A, Help & Troubleshooting] scap99:
Thanks, I was not aware of that feature. It is now disabled.

I'll be leaving work in 3.5 hours, so I'll be able to update after my drive home.
[Nexus 6 Q&A, Help & Troubleshooting] Axel85:
Today I had no problem. Those are the ones that I have:

Bluetooth random turn off

Android wear starting do not disturb mode

Parrot asteroid car stereo that even if connected sometimes and displaying the caller number and name has no audio, and the audio is switched to the phone earpiece. I have to manually select that I want it on Bluetooth.

My Bluetooth devices are an LG g watch with android wear 1.5 and a parrot asteroid classic with shared internet connection from phone through an app called BT auto tethering, because elsewhere I have to start it manually everytime (Bluetooth tethering is not automatic as wi-fi)

Never had any problems with the same devices and configuration on a nexus 5 with pure Nexus marshmallow instead of a nexus 6 on pure Nexus N
[Nexus 6 Q&A, Help & Troubleshooting] scap99:
Once I disabled instant tethering, my BT did not turn itself off during the day. Also, it connected and stayed connected for my drive home this evening.

I will continue to monitor it, but finally, this seems promising.

[Nexus 6 Q&A, Help & Troubleshooting] Axel85:
Rock solid even for me since yesterday no issue at all. I m on last pure Nexus without the march update... So it should be something with instant tethering

It was certainly there on the Stock ROM that just got released....

Someone else stated the same. Maybe that is a USA only feature (don't know where you live from profile), or something else with Google services or apps, if you have restricted anything. I have Mini Dynamic GApps, maybe a different GApps changes that, dunno. Or maybe it takes time after a new install, dunno. Found this on AP:

I have the instant tethering under settings, Google . Maybe it s related to the halls package you install. I m on the same pure Nexus build with full dynamic gapps 2/15. If it letter I'm in Italy

Today I had the android wear problem, the one that trigger the full do not disturb mode for everything, even special contacts. Apart from this Bluetooth is rock solid, so this bug should not be related
[Nexus 6 Q&A, Help & Troubleshooting] scap99:
Not sure what overnight does, but it is acting up again.

Paired with audio, but no phone.

To further clarify. Phone connected to my F150, and Pandora played audio. The song data never transferred to my trucks screen, so I knew that was the first tell. I tried to voice dial my wife and it failed...Tell number two.

Opened BT settings, toggled off then back on, and it connects both phone and audio.

This is where my woes started last time. I'll be flashing back to the March Security image tonight.

Good thing I just did this the other day, because it won't take me as along this time. :)

I hadn't done anything via fastboot since I got this phone and I was like a blind man in a brothel.
[Nexus 6 Q&A, Help & Troubleshooting] Ugurundu:
