Yes me too. Exactly the same issue. An initial command might work (ie "call mum") but otherwise, as op describes. 

Same here, but Galaxy s9+

This thing bothers the hell outta me! Any attempt to converse with Google Assistant causes this, not just attempting to send someone a message. After this, Google Assistant no longer responds to my calls. OnePlus 7t, latest everything.

I am guessing no one has found a solution to this problem? I am facing the same issue as the OP.

I've been stuck with this issue for almost 3 weeks, I even tried updating to the beta and unregistering, clearing cache and restarting, reinstalling, the whole nine yards.

Exactly the same here on Note 9 with Android 10. So frustrating! Wish I could roll back to Pie as it this is not the only trouble this update has caused me.

Same problem here, Galaxy S9 plus and the problem started after I did the official upgrade to Android 10 yesterday. Also, I found another problem. When I ask it Android Auto to navigate to one of my contacts that has a address it tells me it can find that person. Always worked in the past when I would say it, wish I never upgraded to version 10.

Same here too. Is there any solution to make it work or should we wait for a fix?

Same here. Extremely frustrating. When I get messages, AA will play them, but when I go to respond, I keep getting told "your internet connection is not stable at the moment". I can see my signal strength is full, and am on 4G(LTE). Other things like Spotify / Google Podcasts work fine.

Hi. Same problem here. Android auto says: "Not possible to connect to internet. Unstable connexion"

Same answer here in Germany with Galaxy S9+. "Internet not strong enough", very mysterious bug. Hello to Maintain 😉 ... Mountain View, pls. help us to get happy again with your product.

Update.... Turns out I was a bit previous with the below message. Basically it worked fine for 12 hours only! It is back to being more annoying than ever. I'm regularly in the car for 3 hours a day, so being able to respond to all my messages whilst driving was a big positive. Now however, it is a great source of frustration. I'm not the kind of person that uses foul language. However, every time I hear "this Internet connection isn't stable at the moment" or something similar, I find the air is blue with the tirade of expletives that involuntarily escape from my mouth in a torrent of abuse towards this app! Please please please get this resolved ASAP. 

I am having the same problem.

Same problem. Galaxy S9+. Just upgraded to Android 10 as and One UI 2.0

Yeah, same issue here cannot sms as internet connection isn't stable but can use google to turn on hive heating which uses internet, how does that work?

Same issue as all the rest, Note 9 and Adroid 10... Driving me insane

Same issue for me. Android 10, Galaxy S9 and Pioneer AVH-2400NEX

Same issue with Samsung Note 9 in 2019 Subaru Impreza. So annoying!

Hi everyone,

Yes, this is happening to me also. I hope you will report back to this thread when you find the fix so we can all get this resolved.

Im new to this, I just got my car 9 days ago just learning how to use Andriod Auto and navigation and last night stopped working. Been at the car dealership, worked with On Star and had the dealership do a diagnostic. They claim its the app or my phone. VERY DISPLEASED....whats going on????

Same here. Assistant won't engage via voice command, button on steering wheel works. I speak my message, Google reads it back & asks if I want to send or change, I say send and immediately Google says "the internet is unavailable or unstable," and shuts down. Seems all the other apps work, phone, maps, news, weather, calendar... It's only messaging. This started immediately following the Android 10 update.

Can also agree to the previous said. Short SMS seems to work for me. Long SMS not because then I also get told internet connection not stable enough or to weak.

Same as all the rest. S9+ running Android 10 official, was doing it during the Betas too

Same exact issue with Samsung Galaxy Note 9 on official OTA Android 10. Vehicle is a 2019 Golf R.

Same basic problem. On two phones, one Samsung Galaxy S9+, one S9, started with Samsungs recent upgrade to Android 10, happening on GMC Acadia 2017 and 2019 Subaru Outback.  Error message sometimes says internet unstable, some times says internet not working.  All other Android  Auto functions seem to work.  Tried many common fixes on phone.

Same problem with my Galaxy S9 on Android 10, though I had no problems on Android 9.

Thought I was going mad, glad to see it's not only me suffering with this problem.

Same here on my Note 9.  Started immediately after the Android 10 update.

Same here S9 Android 10 ATT running  AA 5.0.500.224 on 2017 Chevy MyLink.  Trying to send text message via voice command,  unstable connection error.

Same thing happened to me  my Note9 after the 10 update.   I will give it a few more days if it is not resolved I will be going to another brand that has a much more stable hands free system.

Fast solution: Downgrade to Android 9 (Pie) with ODIN tool. Check these website https://sfirmware.com/ Download the right firmware of your device/country, download ODIN Flash Tool. One hint: Don´t use the HOME_CSC, because last app updates fitting only to Android 10 so you will get a boot loop, use CSC for factory reset. You will find every instructions how to do this on the mention site and tutorials in YT also. Be aware about loosing your warranty of you device probably!

I am having this issue and went so far as to factory reset my phone (after determining that the phone was the problem by experiencing the issue in a rental car as well) without success.

I have a 2019 Ram 1500 Classic. I had to download the Android Auto app on my phone for the music, hands free phone and text capabilities. It all worked perfectly, and then my phone updated recently. I cannot ever send a text now. Every time I try, I get a whiny voice come on that says, "This internet connection isn't stable right now" and it stops the process. I can have a full signal on my wifi and it doesn't work. I get the same message. I can have full bars showing on my data connection and I get the same message. Also, now the voice activation, "OK Google" or "Hey Google" no longer work. I was going to deleted and re-download the app, but since the update I cannot delete it anymore. Any ideas?

I have a Galaxy S9 Plus which I have absolutely LOVED until this One UI 2.0 update. I too am having this issue, I also have a brand New Hyundai Kona and I was loving the completely seamless integration with my phone and car, I was completely hands free. Now not only does Google Assistant NOT work with Android Auto, when I use my mic button on the steering wheel to get Google to wake up, I will say something like "send a message to my wife." it will go through the whole process and then give me the "this internet connection is not strong enough at the moment" error or it will give me this error somewhere during the process. I have not been able to send a single message since this update. I am also having memory issues on my phone as I have seen others complain about. PLEASE, PLEASE, PLEASEEEEE fix these issues. My phone which was virtually perfect until now, is useless for some of the main things I need it for!!

My Google voice and AA started to work tonight when completed the Google Link my Voice profile on the assistant.  https://support.google.com/assistant/answer/9071681?co=GENIE.Platform%3DAndroid&hl=en

Any solutions yet dangerous driving and having to unplug phone and reply to text......

Google AA Team, have you tried unplugging and plugging back in? Sometimes it works for me.

Same with me as well. S9 plus received the One UI 2 update when this started.

Come on Google fix this. I am able to use every function. But for some reason it won't recognize voice commands I have to hit the mic button and text always say no internet connection. Isnt it suppose to switch to mobile data? Just started happening 3 days ago. S9 phone 2018 Silverado

Same here. It happened after last update 3 WEEKS AGO. Note9 user

Same thing  here in uk Samsung note 9 and  Hyundai i10

Mine just started doing this after the last update from Samsung on my s9plus. Before last week I didn't have any issues with it.

Same error here at Spain with Samsung Galaxy S9+ updated to latest version (Android 10) with the carrier O2

Same error here with Samsung Galaxy S9+

What is wrong with Google?  Just shucked out $47000 for a new car so I could use android auto and it doesn't work! Get error messages and the voice assistant doesnt work! Should have gotten an iPhone! My daughter never has problem with apple play.

I am experiencing this exact problem following recent update (not sure if update to android 10 or android auto 5.0.500224 or a combination of the two. Am using Samsung note 9

I just updated my OS this weekend and now I'm getting the same problem.  It was fine for more than a yr but now it's impossible to send a text message.  I'm using an S9

This is a pretty widespread issue. I'm surprised it took Google so long to find it and more surprised it's taking so long to fix it. Doesn't DevOps mean they can get fixes for major issues like this out fast?

Same trouble here in Italy. Samsung S10e updated with the last firmware release (Android 10) last Monday. After that, I got the trouble: "interner connection isn't strong enough" and the automatic voice recognition stopped working.

Same issue last three days. Receive WA and SMS messages; unable to initiate or reply. No other voice commands are affected.

Yep, having exactly the same issue with my S9+.

Bei mir auch das gleiche😡 Galaxy S9 mit update auf Android 10.

To save people time,  there are no workarounds unless you want to downgrade to Android Pie (9) - I have not tried that -- so no guarantee that works.  I can sit in my car in my garage and connect to my home wifi (very stable and reliable) and still get the unstable internet connection (or not strong enough) issue when I try to send a dictated text via android auto. I have a Galaxy S9+ and the problem started with the recent Android 10 upgrade. I guess I am going to have to wait for a fix.  Highly annoying.

How about an update from Community Specialist Paul - Android Auto Team?  It has a been over a week since last update.

Come on Android Auto team this is poor you should have found a fix by now!!

Same issue 2020 Malibu running android auto

Same issue 2018 dodge durango. Started immediately after the android update her in the last week or so.

Same issue as well.

Same here and apparently there's no fix yet??

Just like everyone else here,  SAME! 

This looks to be a Samsung problem....I too have the exact same issue and I have a note 9.

The same with me Chevy equinox 2018 and a Samsung Galaxy 9s+ no hay Google no more or texting and say no internet connection

Same here on a renault captur.   Absolute ballache!

Same issue. Samsung Note 9,  android 10 is. 2018 Subaru Outback with starlink. Problem started when I updated to android 10.

Same issue Note 9, Jeep Grand Cherokee w UConnect. Driving me crazy. 

Same issue. Galaxy s9+, 2019 Honda Accord. Android auto.  Wiped cache.  Uninstalled.  Even tried factory reset if phone and car. No luck

My issue is on Android 10, too.  Coming thread appears to be Samsung in all of these problems. This latest update made Android auto as unusable as the Apple Auto.  I left Apple to get stability and reliable and customizable phone.  Might as well downgrade to an iPhone

After updating my Samsung S10+ I found these problems. Annoying as I used the features a lot and relied on them so I didn't have to keep pulling over! If I'd have known I wouldn't have updated my phone as it was already an issue.

I bet it is the new version of Bixby that is causing problems.  too bad you can't uninstall it or delete it or disable it to test it out

This is a road hazard and creates a deadly situation.  Fix your issue so people won't text while driving.  I never text and drive but so many others do because of your bugs.  Fix your issues!

Same here. Attempted everything to try and fix, reboot, change cables, refresh apps etc. No go! Any assistance will be gratefully appreciated.

Same problem note 9

2 weeks, still no resolution, nor comments from Google in almost a week. What's up with a resolution?

Same problem here too. Using this in a work vehicle while on the road. 

Same here in s9+ since Update to Android 10

Same issue s9+.  Extremely inconvenient.

Galaxy Note 9. Same problem. Sucks.

Galaxy S9+ and same issue. Some updates from Google would be good!!!

Same error message, but it only happens when attempting to send or reply to a text. I can make and receive calls fine, play music, use Google maps with no issue. Only outgoing texts. Has anyone else noticed that the voice that gives the error message sounds slightly more "robotic" than the normal Google Assistant? Strange...

Can not use voice text since Android 10 update and the app became a system embedded app that can not be uninstalled. Cords and phones have been replaced, not resolved. Have done hours of research and troubleshooting, no luck. Looking like iOS is going to be in my future.

Here in Austria too. Received yesterday the Android10 Update from T-Mobile Austria. Since then no "OK Google" working in the car and whatsapp does not accept new nessages with error ""weak internet connection".

I have the same, Note 9, Android 10.  Going to get Iphone later today.  This is too dangerous

Judging by the created and resolved dates on some of the issues listed as "recently addressed" in the Android Auto Known Issues post, it seems like we'll be waiting a while:

Same here for me S10.. Internet Connection not stable...

Same for me was fine till android 10 update using Samsung note 9. Really loved this function.  When will there be a fix? For this unstable connection error when replying to a message .

Same here lg g8 andriod 10 with andriod auto

Hey Paul, how about an update?

Really hoping they have a fix soon...I'm about 2 "hey google" fails from switching to apple.

Well I gave Android 3 weeks and there has been zero communication on this issue.  Going to get my first iPhone tomorrow.  Thanks Android for showing us how much you really care about your customers.  Really sucks as I have owned every Note and loved it.

Still having this issue for last 2 weeks on s9 with latest updates. Any news as to when this should be getting fixed or is it a case of wasting my time choosing a car that's supposed to work with Android phones.

I have the same issue on a galaxy s10 linked to a VW Tiguan. I can't send/answer  messages anymore but I can ask Android auto to call someone

I  noticed this screen pop up yesterday. I went ahead and left "this phone" selected but also selected transferring files/Android auto. It then would let me successfully send texts. I am still not able to successfully answer calls from my vehicle screen though. Glad we could test in production......not

Add me to the list. S9+ recently updated to One UI 2.0. Using on a 2019 GMC Terrain. I hope it is rectified soon!

Same here. Using Galaxy S10 / Android 10. Skoda Octavia 5E with Columbus connected AA with USB. WhatsApp support decline to check issue without reason.

I am having the same issues with my Galaxy S9 & Android Auto. After dictating a text message & say Send it tells me my internet connection is not strong enough or my internet is off line.

I have the same issue.  It seems to be just an issue with text messages.

This is doing my head in. It worked perfect last weekend now just keep getting connection not stable

Same here. I´m using Galaxy S9 with Android 10 on Mazda with MZD Connect
