The Unofficial Android Auto Thread

Hi All,
I've been extremely excited about the integration of my smartphone with my car for a while. Almost anyone who would be in the market for a motor vehicle with an advanced head unit would also already own a smartphone with data access.
However, like any new use of technology, there are growing pains and Android Auto is no different. I have struggled through a few issues already and continue to grapple with others. A huge difficulty I had was simply finding discussion threads. Do I look on sites that focus on cars? On Android Auto? On Android OS?
So here it is. I'm starting a thread to pull together the most common problems and their solutions. Also, please note - I am not an expert in any of these things, just a user. I will give credit where I have a source but I am just gathering the info into one place and adding it to my own observations.
I haven't decided how this thread is going to look or if it will be small or big, so I will save the first few message placeholders in case and I will add known problems, work-arounds, and identified solutions as they come.
Hopefully this helps out some other users!

Troubleshooting:
I strongly suggest you make sure you have a good quality USB cable and confirm that you are able to connect your phone to your computer and transfer a file (some cables will allow charging but not data transfer).
1. Problem: Bluetooth won't pair, won't connect, etc.
Possible Solution:
It appears that Android Auto will attempt to create a BT profile. So
a) Delete the pairing on your cell phone
b) Delete the pairing on your car head unit
c) Turn OFF bluetooth on your phone
d) Plug your phone into your car's head unit. Depending on your settings, you may need to tell your car to launch Android Auto and you may need to select the device. If so, make sure you are selecting it in Android Auto (NOT Bluetooth pairing). Respond appropriately to any requests for authorization on your phone and car.
This should leave you with a properly paired device and car.
2. Problem: Every time I launch Android Auto, I have to pair my phone again!
Work-around: Once you have a working AA connection between the car and your device, go into the settings in the Android Auto app on your device and turn off the option to "Add new cars to Android Auto."
3. Problem: Android Auto notifies me of a new message but won't read it out loud/but starts to read it and cuts off.
It looks like there is a conflict between Google Now, Android Auto, and the Bluetooth handoff with the car head unit. Kudos to XDA member BuildaWall for discovering that turning off the BT headset option in Google Now fixed it for some people. I did a little more testing and found that forcing Android Auto to make your phone the primary source of audio seems to be the other piece.
UPDATE:I applied the August CM-13 Snapshot and this workaround no longer fixes the problem. I have reheaded it as a possible work-around as it might fix the issue for people on slightly older ROMs
UPDATE Sept 27/2016: I have upgraded to stock Nougat (Android 7). This issue still exists. However, after reading this XDA article, I tested an accessibility option. AA began reading the messages once again.
Possible Work-arounds:
A) Several people reported that their Media volume on their phone was being changed to zero when they plugged into AA. Some also reported that turning USB Debugging OFF fixed this issue. If you don't know what USB debugging is, don't worry about it; you would have to have intentionally turned it on. For volume, tap your volume rocker but then tap the drop down on the pop up volume notification.. It will expand to multiple volume sliders. For simplicity, make sure none are zero.
B) On your phone, go into Google Now, Options, Settings, Voice and then turn off Bluetooth Headset. This was reported to help by some but not didn't help for me.
C) On your car's head unit, in Android Auto, select a music option (I have Spotify and Google Play Music, but I think any audio source app within AA will work). If you don't want to listen to anything, just play and then pause/stop it but you CANNOT go back to the car as a primary source (eg radio or sirusXM).
D) On Nougat (Android 7) go to settings, accessibility, and enable one of the options (I have tested Voice Access, but in theory, activating any accessibility option should reactivate the message reading in AA.
4. Reported with work-around by @ReppinTheSouth - Android auto either being laggy or flat-out disconnecting
ReppinTheSouth observed this on a Pioneer avh 4100 and a galaxy s4 and reported August 7, 2016
Suggested Work-Around: Clearing the phone's cache periodically seems to help a lot. I also added a swap file which has seemed to help even more.
5. Reported by @ReppinTheSouth - When driving in maps with voice commands enabled, it will freeze sometimes right when a voice command is about to come on. My GPS will no longer track and my head unit at least an Android auto is completely unresponsive.
I'm not listing this as a work-around, as it doesn't resolve the problem, but is still good to know: @ReppinTheSouth advises: This only happens when voice commands are enabled & Unplugging and replugging the phone gets the head unit out of its frozen state.
More to come!

Tips and Tricks:
I will use this page to list tips to improve performance or usability that don't fit under troubleshooting.
1. Keeping the phone screen alive and accessible.
Please exercise safe driving habits.
TL; DR:
Turn on Developer options
Turn on Stay Awake
Optional: if you have a security lock you may want to add your car Bluetooth as a trusted device for smart lock so it doesn't lock you out.
Details:
Android Auto changes your screen timeout to 15 seconds every time it is activated. When combined with its flaws with hangouts chat notification (no groups, can't initiate a new chat without certain contact book entries, can't access chats that began before connecting to AA) it is VERY frustrating.
Access the Developer Options menu
Settings >>> About Phone
Scroll to the bottom and tap the Build Number option seven times in a row. You will get some sort of message saying you have access to developer options. You only need to do this once.
Settings >>> Developer Options
Make sure they are turned on. Next turn on the Stay Awake option.
Your phone will now allow dimming but won't turn off the display.
Optional:
If you use a security lock on your device, you may want to authorize your car Bluetooth connection as a trusted device under smart lock so it won't lock while connected.

Thanks for this thread Mad Medik.
However, I also have the same problem as number 3, but the workaround doesn't work.... I changed my phone Bluetooth Headset setting to off and I was playing my spotify music through Android Auto. Am I forgetting something here? what versions of AA and Whatsapp do you use?

Good thread and it is much needed as far as I am concerned. I have a Pioneer avh 4100 and a galaxy s4. One of the issues I have had is with Android auto either being laggy or flat-out disconnecting for no reason. One of the things I have noticed is Android auto seems to be a resource hog. Clearing the phone's cache periodically seems to help a lot. I also added a swap file which has seemed to help even more.
The other issue I'm having which I can't solve is when driving in maps with voice commands enabled, it will freeze sometimes right when a voice command is about to come on. My GPS will no longer track and my head unit at least an Android auto is completely unresponsive. I have to unplug my phone and then plug it back up to get it to work. This only happens when voice commands are enabled. I have not been able to resolve this issue.

Hi NLatuny & ReppinTheSouth!
@NLatuny - Thanks for the info. I just updated my Nexus 6p to the latest (august 2016) CM13 Snapshot, and the work-around no longer fixes the problem for me either. I've updated the original post. I think your request for version numbers is probably a good idea moving forward. I will update the original post to suggest that people include that in their posts.
@ReppinTheSouth - Thanks! I will look at adding those problems and your possible solutions for the lag to the top of the thread

Might be good to add a list of things you can and cannot do. For example, I found the other day through just trying you could ask various questions.
How old is (enter famous person here). = Correct answer.
I need to remember some of the other ones I've done. Good thread.
---------- Post added at 10:42 AM ---------- Previous post was at 10:40 AM ----------
Perhaps also add how to get into Developer Mode, and what the settings in there do? The Force Day or Night mode thing is super useful.

I am not sure if this is the righjt place to ask, but I have been everywhere with no answer.
I Have a Galaxy s7 edge in a Mercedes a class. It connects just fine, but I cannot make calls saying "call >name>". Maps, Music, weather works just fine, but when I try to make a call, the woman just replies "not sure how to help you with "call..."". I can dial numbers as well BTW.
Making calls through Google Now works fine as well.
Any help would be much apiciated.

Check your permissions for Android Auto, you may have missed a few.
You can also uninstall and reinstall it.

I have tried all that, with no luck unfortunately

Having had a courtesy car for a few days that had an android auto system in I'm looking to purchase an android auto headunit for my car, probably after Christmas.
Until then I've been using my handsets connected to the aux input on my factory system. However since I got my Pixel handset last week I've encountered a couple of issues that weren't an issue on my m9 handset previously. I've reported then to the relevant support sites but as yet have received no response, so thought I would try you knowledgeable lot.
Firstly, when making or recurving phone calls with the aux cable connected the Pixel defaults to using the loudspeaker on the handset rather than putting through the aux to my car speakers.
Secondly, when receiving a message on WhatsApp i touch the screen too get it to read the message, it does so fine, then tells me I can press the mic soon symbol and say reply. When I do so I'm told "this chat app is not installed or needs an update". The app is installed and is up to date. I can send WhatsApp messages by saying "send a WhatsApp message to...." but can't reply.
Lastly, when I ask it to play specific tracks on Spotify it often comes back with no search results. Songs that I used to ask it to play regularly on my previous device come back as no search results found. Searching manually the tracks are there and can be played. And it isn't all tracks, some tracks are found without issue.
Thanks in advance.
Also hope this is in the right thread, I notice you seem to be taking mainly about the in car systems but as it can now be used on most android phones without a dedicated in car system I figured many would be doing so.

Hi folks, sorry for the absence. My N6P died on me in November and was sent away for warranty repair. Long story short, I'm very disappointed with Huawei and futuretel. Two months later, the process ended with me owning an unfixed Nexus 6P which is still under warranty until February 2017. It has a defective motherboard according the repair center but they will not repair it. So, after 2 months of making do with an iPhone 6 with a broken screen (wife's old phone), I have moved on to a One Plus 3T.
Irritatingly, Apple Carplay worked flawlessly for that time. Typical of Apple it was very locked down and had limited options. But in fairness, it executed those few features very well. Come on Google!

I'm back and will try to get the thread up to date.

Hello, thank you very much for this information, is very useful.
In my case, I have a Le Pro 3 X720 and is nightmare with AA, when I plug the phone on my Hyundai car the phone only charge so I had to change their ROM to lineage is 14.1 (Android 7.1.2) and with this AA starts quickly but after 5 minutes the screen is freeze then change the cable but it doesn't work, I change the cable again with the same result, so I back to use the original leeco cable and change their ROM again, with the same result, after 5 minutes the screen is freeze, the last one is AICP 12.1 (Android 7.1.2).
Do you know how to fix this?
Thank you in advance for your response.

Hello everyone,
i found this thread and i hope that is the correct one for my problem.
In the first page i read that AA set the screen timeout to 15sec when activate, but in my case, the timeout remain also after when i unplug the phone from my car.
If i manually set the timeout to 5 minutes, after the first screen lock, it return to 15sec and this is so frustrating.
So i tried to set the stay awke mode in the developer options, but i see that the description of this setting is "when is on charge" (i'm italian, i don't know the english description, sorry), there is some walkaround to fix the 15sec also after the unplug ?
Thanks in advance

Hi Mike,
You should say what phone and android version you are using. I have used both a One Plus 3T on Oreo beta and an LG V30 on 7.1.2.
The screen timeout sets to 15 sec when I plug in, but returns to normal when I unplug.

Is my Samsung Connect broken?

2 things:
SM-N950F vs. My phone (Galaxy Note8) audio output
Gear Sport preference reset
(links are to cropped screenshots)
First, I somehow have 2 audio devices available at all times and the default is the "wrong" one. Whenever I disconnect from an external audio device (plug-in earphones, car's bluetooth, etc) it defaults to "SM-N950F" which is just silent all the time and I have to manually change to "My phone (Galaxy Note8)" every time. If I open the Samsung Connect app manually neither audio device is listed anywhere for me to change the default or find any detailed info.
Second, no matter how many times I tell it not to show my Gear Sport in the notification panel it "forgets" this setting seemingly at random. Not a massive annoyance seeing it in the notification panel, but it is a massive annoyance that Samsung Connect apparently doesn't give a sh*t about my preferences.
I only got both devices on Wednesday 17th and I set the OS and all apps to update automatically even over mobile data so everything should be the latest version. I haven't tried uninstalling Samsung Connect yet as I'm worried it'll get stuck on the "SM-N950F" audio device and then I have to wipe my phone or something.
Anyone encounter something similar before?

Nokia 7 plus (ver. 9.0) bluetooth problem

Is there any fix to the Bluetooth not working issue for Nokia 7 plus running Android 9.0 ?
I've tried
wiping Bluetooth cache
Selecting don't optimize in Bluetooth settings
Installing Bluetooth scan apps
Nothing works
Phone was great when running ver 8.0 - now cannot connect at all to my Bluetooth speakers...
Can't rollback either as device is locked (datestamp incorrect) .
Thanks
Steevo

I have emailed Nokia and got a reply on the WiFi and Bluetooth issues. They replied with the following
In the meantime, we can suggest you a workaround in order to sort it out:
1.
- Please go to settings > network and internet > 3 dots on the top > reset network preferences. Keep in mind that this will erase all the Wi Fi passwords.
- After that, please do a Soft reset: Press the Power button and Volume UP button simultaneously for at least 10 seconds, release them when you feel the phone vibrate and you see "Powered by Android" on the screen.
2. Check in safe mode:
- Press and hold the Power button.
- In the window that will appear on the screen, select and hold the "Power off" option.
- It will appear a new window called "Safe Mode". Then, press OK.
The device will restart in safe mode. An inscription about this will appear at the bottom left of the screen. After going into safe mode, use the device as usual. Check if the problem has disappeared. Remember that only preinstalled applications are available to you. If you want to go back to the normal mode, you just need to restart the device.
I haven't tried it as of yet, need time to do it.
The issues I have is sometimes going from home to work and visa versa the WiFi or BT will not automatically connect all the time.

Google destroyed Bluetooth on Android 9. I personally had no voice call functionality in my car as soon as my 6.1 plus updated to Pie. I've since returned it and am now rocking a 5yo LG stuck on Marshmallow... but BT calls work in the car.
Nothing you try to do will fix your problem until the issues are sorted in the core OS. Google need to pull their head out of their arse and get it sorted so manufacturers can push OTA. Nokia have lost me as a customer.

I am running pie with march update and bluetooth works fine in my car. Video calling, music plays without any issue.

Bluetooth issue on my Nokia 7 plus fixed
I had an issue with Bluetooth after Android 9 upgrade.
I could connect to previously connected devices but my handset would not detect any Bluetooth devices. So, i was unable to connect.
Based on some of the comments here, i reset network, wifi, Bluetooth. Still didn't work. Then i reset app preferences and notifications. This worked like a charm. Now i don't have the problem anymore.

thanks man this saved my life, i Just bought a new headphone (sabbat e12 ultra ) and it wouldn't connect even though its pairing fine , and connections reset didn't work but who would have thought apps and notifications reset will solve it , thanks again .

I got working my sabbat e12 ultra by
Going back to oct 2019 update.
via fastboot, fastboot getvar current-slot, this will determine the active slot if its a do this command
fastboot --set-active=b and if b fastboot --set-active=a
This may wipe your data you may backup

I am so glad I got rid of this smartphone from Nokia , which has some defective hardware and software.
The freeze was a never ending issue.

Bluetooth earbuds can't connect.

Hello, after 2 and a half years using the phone and not having big issues, just the known (red tint screen etc) and saying that the phone itself still stands good, i now have a problem. I just purchased the Creative outlier air v2 earbuds and i simply can't connect them to Nokia 8. Phone hasn't been tweaked , is stock Android 9 with the last October update. The phone discovers them i pair them, i hear the "pair successful" from the earbuds but they don't connect , instantly they appear in "Saved Earbuds" section in Bluetooth settings and the earbuds flash as they supposed to when they are disconnected from a device.
I tried pretty much everything i can find, Bluetooth on-off, developer options on-off restart, clear bluetooth app cache, clear apps settings even clear WIFI/Bluetooh cache (bye -bye wifi ssids) tried to changed the avrcp bluetooth versions to 1.4-1.6, select aptX codec etc but nothing changed. The disable bluetooth a2dp hardware offload is grayed out so i couldn't changed that, but don't know if it will make any difference.
So is there a thing i can do to make them work, tweak/re install firmware or version of bluetooth ? Or i just hit a situation that the two devices just don't go along.
Just for the record, the earbuds pair and work fine in my laptop and even in 2 Xiaomi redmi 5 i tried to.

IDK if it helps, but Creative recommends to use the SXFI app (https://play.google.com/store/apps/details?id=com.creative.apps.superxfiplayer&hl).
Install this app
Create your profile
Connect the earbuds to your device
Have you tried it already?

Yeah i tried that, creative suggested some methods mentioned it this site, for different Nokia models, but it was basically what i've done already(clear apps, cache, reset phone) I've given up, the only solution is just use different phone...

Question Bluetooth disconnecting frequently

Got my 21 ultra four days ago. Came from a Note 9. I have a Motorola headset on most of the day. Never had an issue with a disconnect with my Note 9.
About maybe every 1-2 hours I get a notification through my headset that the Bluetooth has disconnected and reconnects fairly quick after. That happens when I'm not on a call.
When I'm on a call it doesn't alert me but I can tell I lose the person I am talking with for about 5-10 seconds.
I have done all the clearing cache, resetting network, etc. Was hoping someone might be able to give me any tips.

Have you tried with another Bluetooth headset? It will help diagnose whether the issue is with your phone or the headset.
I have been using my S21 Ultra with the following bluetooth devices and not lost connection unintentionally even once since I've owned the device (across all software updates so far)
1. Galaxy Buds Live (use them for hands free calls all day)
2. Anker Soundcore 2 BT Stereo speakers (for music)
3. Mi Outdoor BT Speaker (podcasts at night before sleep)
4. OnePlus Wireless Z BT neckband earbuds (for running and other exercise)
5. QCY Airdots TWS earpbuds (general purpose audio)
6. House of Marley BT speakers (Hi-Fi audio streaming)
Please test the connection with another BT headset and check if the problem persists.

That won't do it. It's still active; those buckets represent the ones you can alter and even those may not "take".
You toggled on adaptive battery etc in Device Care*. The only thing that should be enabled is fast charging.
The Power Mode should be Optimized or higher.
Clear the system cache as well.
Hopefully this will cure the cutouts... it worked for me and stopped a lot of other erratic behaviors. Battery Optimization etc was always a dog. Android does fine by itself. However some apps like Brave need to be closed out or they run in the background wasting power.
If you're battery life is bad or gets worse let me know.
*I'm running Pie on a 10+ but they should be similar.

Sometimes apps will interfere with Bluetooth operation and clearing the cache can solve the problem. For Android phones, go to Settings > System > Advanced> Reset Options > Reset Wi-fi, Mobile and Bluetooth

After all power management is disabled clearing the system cache on the boot menu advisable and maybe a network reset.

Edit: Looks like more than one user is having this issue. So could be an issue with the phone itself instead of the headset. I haven't had a similar experience so I don' think I'll be able to add anything of value here. Hence removed my previous suggestions.

It happens to me very often... I use Buds+ and Buds pro. I am connect over bluetooth to my laptop, galaxy watch 3 and buds. During phone call it disconnect and I must connect on py phone again. Mostly I see it just change output to phone. And I have to change phone call output to buds
It is very frustrating. Cos It happens during call. And I have to manualy change to buds during call... Do I have any weird option enabled so buds diconect durring call?

Maybe because of so many bt devices, try using one or two at first.
Make sure Wearables is up to date. Samsung sometimes pusher out updates frequently, it may fix it. Lol, I waited almost a year for the Buds÷ sound fix
Network reset. Then add only what is needed.
Clear system cache.
Hard reboot.
