Hello Garmin people, since yesterday I have really furstraring issue. I have Xiaomi mi A1 and yesterday I updated to 9.0 android pie. Since then the Bluetooth connection is really bad and keeps diaconecting all the time. In the past I had stable connection for 20 mettres and now it keeps disconnecting even if I move for 2 meters. Sometimes it reconnects but it is really unstable. I tried almost everything I know. Removed the device from Garmin Connect, unpaired device,cleared Bluetooth cache plus data, hard reset of the phone and still it keeps disconnecting which was not the case one day ago. If I pair my Bluetooth speaker I have absolutely no issue even if I go in the near room and I have walls and doors between me and the phone. I don't know how it is possible this in Android pie. Any ideas how I can bring back my stable Bluetooth connection ?

    I had the really same issue with my Fenix 5 sapphire after upgrading to Android Pie on my Xiaomi yesterday.
    But I was able to fix it following the informations given in this thread :
    https://forums.garmin.com/forum/into...id-pie-problem

    The problem doesn't comes from GCM, but the way we have to pair the device and the phone under Android 9.
    It seems that we have to pair it with the phone, before going into GCM app.


    Hi Pasitia,

    Can you share the exact steps you did in order to solve it. I tried pairing first from the watch, then from the phone, but I will do it once again if you give the exact steps you took.

    And are you sure that while you are in GCM and looking or changing some settings the white bubble Fenix 5 is connected does not appear every 30 secs ?

    Thanks !

    Here are the steps I followed :

    1) On the smartphone, go to Settings => Connected devices => Previously connected devices => Forget the Fenix device.
    2) On the Fenix, go to Settings => Phone => Pair Phone.
    3) On the smartphone, go to Settings => Connected devices => Pair new device.
    5) Android will now ask a pin code. The Fenix shows a 6 digit pin code. Enter the code on your smartphone.

    Once the device is connected in Android, open Garmin Connect and it will recognize your device again.

    What I noticed is that the connection status icon on the fenix, is now nearly always off. But I'm still able to receive instantly my notifications, even when the icon is off.
    I think Android 9 is managing bluetooth connection a different way than before.
    I'm not an Android expert, but I think one of the main improvement with Pie 9 is the battery management.
    This should impact the bluetooth connection with garmin device, that doesn't use a permanent connection with the phone.
    It seems that the bluetooth connection is activated between the device and the phone, only when there is some information to transfer.
    Perhaps this is why the connection status is always off from now.

    Maybe a future version of GCM will clarify this ...

    I tried this method and the connection is better but still is disconnecting after some time. At least I think the annoying pop up Buble in the app stopped to show every 30 secs. Apparently the issue is between the GCM and Android pies new Bluetooth battery optimization. I have really
    low expectations if this will be ever fixed as it is really tricky to reproduce and I don't know if only Xioami devices are affected.

    Update. I don`t see any improvement. Connected the watch in every single way possible to the Android. Still disocnnects and says "waiting for phone". In the GCM the buble "Fenix 5 is Connected" appears every 1 min and you cannot do any changes if you are not fast, because it brings you back.Sometimes it re-connects in a second sometimes takes 2-3 mins. When it says "waiting for phone" and I call my phone it does not trigger the Bluetooth on the phone.Connected the watch to an iPhone and works without any issues. Android Pie seems to be the problem and the solution seems to be somewhere in the nowhere.
  • Today, everything is fine. It worked fine during my morning run of ~50 minutes, then I turned it off, and sync'd via cable. Disconnected and turned watch off. Turned it back on by charging via cable connected to my laptop (different computer). Activated Garmin Connect on my iphone. Tried several setting changes and faked a strength workout. No problems so far. ??? IOS is not updated, and watch is still at 12.0.

    This thread is for problems with Android 9 not with IOS :)

    I had a chat with Garmin support unfortunately it seem we are the only one with those issues on Android 9. I thinks it is from the Xiaomi and the software. I am tired of looking for a solution at the moment and hope a miracle will happen :D

    But this is pure Android, there is no additional software...
    I found in internet other threads for Bluetooth connection problems similar as ours with Android 9 and other smart phones.

    Yesterday I sent a bug report to Xiaomi through the phone for this problem and I hope that they will check it...
    You can do this too - find the "Feedback" icon in the phone apps. The more users report the bug, the more likely it is Xiaomi to do something :)

    Yes it is consired as a pure Android but I believe Xioami does some minor adjustemnt in the background (may be not so minor). I sent as well feedback yesterday via the Feedback app. Hope for the best, otherwise will have to change the brand and the phone because the watch is 3 times the price the phone :D
  • Same problem also for me after updating my Xiaomi Mi A2 Lite to Android 9. No kind of problem with car bt or headphones but the connection with Garmin is not stable and the most annoying thing is that the continuous connection/disconnection drain the wath battery very fast (about 25-30% por day).

    If someone else find a solution, please help. I tried all the possibilities with energy saving and different way of pairing
