CM12.1 and Android Auto: "Connection Error 7" - ONE Q&A, Help & Troubleshooting

I'm currently on the latest CM12.1 Sultan-Mod. Last week I got a new car which supports Android Auto (Volkwsagen Columbus Headunit), at the beginning I got a connection a few times, but all the time with frequent connection losses ("Error: USB Device" shown on Headunit), the longest period it worked was about 1 hour. Today on my phone I got the message "Communication Error 7", now it's not possible to get a stable connection at all.
I've tried removing the car from the auto app and removing the auto app but without success. Has anybody been able to get a working connection between a CM12.1 device and a car?

Missing features after resetting mobile
Hi,
I am using OPO with CM 12.1. Yesterday i have reset my mobile and few apps and features (Screen Pinning,Screenshot,Menu button ) are missing after resetting my mobile. Please let e know the solution.

I've tried different CM13 Nightlies and CM12.1 without success now. Seems like Android Auto won't work with the OPO at the moment.

For future notice, I was having this same problem all of a sudden on my Nexus 6P, found how to fix it.
Uninstall updates for Google Play Services, it's a buggy install that is doing it. Found a few other forums talking about it, did it myself, and even after it re-updated, everything is working fine. I had to plug it in and unplug it several times, and it finally gave me all of the prompts again to start like new.

MDA Compact IV Can't Turn Wi-Fi On

Hi guys, now something odd is going on with my MDA Compact IV (aka Touch Diamond). With the original T-Mobile ROM I could connect to Wi-Fi fine. When I upgraded to Dutty 2.6 ROM I could still connect fine but after a couple of weeks it stopped connecting for no reason I could see. When I mean it stopped connecting, basically, when I click the "Turn on Wi-Fi" option, the little spinny ball pops up to show you its trying to do something but then nothing - it stays unticked and there is NO error message. I have tried setting power mode to best performance and changing the wifi to connecting between "The Internet" and "Work" - the two options available (I think it used to work on the default Work settings) - but it still doesn't work. I just upgraded to Dutty 2.9 and it does exactly the same thing - no error message so I am not sure how I am supposed to diagnose the problem!
Anyone have any ideas? Any help would be much appreciated!
Hi,
I'm having the same issue with the same device.
I already reverted back to stock spl/rom/radio but the problem still remains in every rom i try.
The only solution is to get out the battery for at least 10 minutes and try again.
It should work until it stops again.
Thanks for the message, I just managed to fix it on mine about 5 minutes ago. In the end, I cleared my internal storage and hard reset it and it finally worked. That is after trying various ROMS/Radios. Lets see how long it lasts....
Hi,
I'm having the same issue now... It just started yesterday - And I have no clue - except, that I recently have used the device connecting my laptop using internet sharing...
Any clue someone? don't want to hard-reset...
Thanks!! J

Bluetooth Metadata & Connectivity Issues

I'm running my OnePlus One and I've had this issue since the first CM12 update to Lollipop, but with the recent OTA claiming to have fixed "Bluetooth" issues and this still isn't fixed I'd really like to know if theres a solution.
Basically I have an aftermarket Pioneer headunit. When I start the car and it attempts to connect to the phone, the phone takes almost a full minute before it connects. Prior to lollipop it would connect in 2-3 seconds.
I stream music from my phone using Spotify and Google Play Music, using either has tons of stuttering over Bluetooth. Atleast once every minute or so, it will stutter for a second or two.
And finally, the radio only ever sees the song information for the first track that plays from when the phone connects. Skipping songs, restarting the app won't change the song data that's being sent out. The only thing I can do to update is to restart the phone and it will get stuck again. This is by far my biggest gripe because it worked fine on KitKat and JellyBean for me on CM11.
I really like Lollipop but neither CM12 or OxygenOS has solved this issue for me. Right now all I can think of is just flashing an older CM11 rom but I'd like to know of any alternatives, whether that be a different ROM or whatever. I've also read up that someone just flashed an older CM11 radio/modem onto CM12, but I don't know if that was a solution, there was no follow up post.
It does this with nearly every aftermarket radio I've paired my phone with (friend's cars etc.)

No connection to LG G Watch since 6.0 update.

Hey guys,
2 days ago I updated my German z5 due pcc to Android 6.0. Since that I'm facing issues with my smartwatch. Directly after the update, I didn't get any connection to my watch again. I tried do reset the watch and installed android wear app new. Luckily the first connection is always possible, but after first setup I´m not able to connect again. Does anyone has another hint, then reset my z5 like the support of Sony did? I don´t have the feeling, that a reset would, because it is obviously a Bluetooth issue. Thanks for any help and see the screenshot attached. The screenshot shows, how android wear is always stopping when trying to get a connection.
Update:
Yesterday something strange happened. I settled my watch the whole day in it's loading station and in the evening I saw, that my watch was muted like my phone was. When I opened up android wear, I saw my watch was connected, also every app was synced. So I started to install some new wear app and the all get synced. But when I pulled up my watch from the loading station, the connection immediately got lost and until now, I'm not able to connect again. Now I'm pretty sure it is an Bluetooth bug, coming with the android 6.0 update of my z5.

So I have been reading about and there are loads of bluetooth issues with Marshmallow even with googles own Nexus devices I know it's not going to help you... http://ausdroid.net/2015/11/17/google-working-fix-nexus-6p-bluetooth-issues/ so I think google need to understand what the problem is a provide a fix for the other manufacturers to include.
My best guess is bluetooth is not behaving nicely in the new google ART cache which is supposed to fully replace delvik in Marshmallow.

Bluetooth keeps enabling

Hi!
Im on exynos version of S7 and i have a little problem.
On apeq stock firmware (i didnt noticed this before), when locking device / turning off screen, phone is activating Bluetooth on its own! Ive noticed Bluetooth icon disappearing moments after turning screen on. There is battery drain from Bluetooth sharing (or someting simmilar, i have non-english version of android set).
Bluetooth is disabled in options and Bluetooth scanning is turned off. I do not use any kind of Bluetooth hardware /dongles.
Is this a common bug?
I haven't seen or heard of this before, but just thinking about it...Do you have any location based apps running that night trigger your bluetooth like IFTTT or My Places?
No, i've got no such things besides standard google apps. No new apps since last rom update.
Well, i think i have found a guilty app.
I tried factory reset, then i have downgraded to APC8 firmware and still, after app installation bluetooth started to show up.
By trial & error method i started to delete apps one by one and found out that SwiftKey was the "bad apple". Unfortunately for me - it's my favorite keyboard...
Well, after uninstalling and replacing it with google keyboard all is fine for now.

App updates hang / delayed notifications

Recently on my Note 10+ (SM-N975U1) running stock Pie and Dec 1 2019 update, I have been experience 2 issues.
Notifications for some apps are delayed
App updates hang on Google Play Store
For the app updates, they stall with "Download Pending" or the download stalls with <100% complete.
Resolution steps that have NOT worked
Clearing cache and data for Google Play Store
Rebooting phone
Rebooting into Safe Mode
Changing from Wifi to Cell Network Data and vice versa
Stop/starting app updates
Current Workaround
Closing/swiping the Google Play Store and opening it again. It will eventually complete downloading after multiple attempts and install/update an app - you will have to repeat this continuously for every app you want to install or update.
Is there anyway to debug this without doing a complete reset?
This is a problem I've had on many phones over the last few years. It took me a while to figure it out but it's bluetooth related. More specifically, I had the "Dynamic Lock" option enabled on my Windows 10 work laptop (which basically just locks my pc when my phone gets far enough away). I disabled this and now all my notifications come immediately and play store updates work as they should. I realize that you may not have that enabled and if that is the case then turn off your bluetooth for a while and see what happens. It worked for me and several others on the samsung community forum.

Thank you! I turned off Bluetooth but nothing happened but after I rebooted with Bluetooth off everything started to work again. Is there a permanent fix for this? I am assuming turning back on Bluetooth will cause this to happen again? The strange thing this never happened to my Note 8.

I have no idea why this happens. What I do know I have had this issue on LG phones, Pixels, and Motorola's. It isn't a Samsung thing. I think it's an Android Bluetooth issue.
This is an old thread - but in case someone else finds it, I came across someone's suspicions in another thread that their Plantronics headset was causing some kind of problem with their Bluetooth. I began unplugging my Savi headset when not in use and it seems to help... YMMV.
This has been going on since Pie; made me upgrade from my Note 8 to Note 10 and it came right back. Infuriating.
You may also want to try to rub a lucky stone and do some chanting as well, because it's about as effective as hoping for a fix after all this time.
