Hey @qtwrk
I encountered a similar behaviour on a fresh Lineage 18.1 + MicroG installation on a OnePlus 6T. Every time I rebooted the device, or sometimes randomly, device registration turned off and thus push notifications did not work as expected. Fortunately, I found a solution on https://android-freaks.de/forum/thread/539-fix-push-probleme-mit-microg/

The trick is to add the following two lines

<boolean name="checkin_enable_service" value="true" />
<boolean name="gcm_enable_mcs_service" value="true" />

in the file /data/data/com.google.android.gms/shared_prefs/com.google.android.gms_preferences.xml. In my case, only the <boolean name="checkin_enable_service" value="true" /> was missing. After a reboot, I was immediately prompted to allow a bunch of apps to register for push notifications and now everything works as expected.

Hi, @hemker

Thanks for the info, but unfortunately that's not option for me as there is no way to root this device to get access to /data partition

I was actually looking for some kind of automated app that can be set to auto-dial that code every certain time :)

Are you sure that EMUI doesn't behave like FlymeOS ? In FlymeOS when you slide out MicroG of recent applications screen, the MicroG process is killed and the GCM service is automatically disconnected.

The only way to restart the MicroG process without making it appear in the recents applications screen is to restart the phone.

Hi @abda11ah

Yes, for that I am pretty much sure the MicroG was NOT killed because I frequently got notification like "microG is running for long time and consuming battery , consider to kill it " that kind of message

meanwhile , I also noticed something peculiar , it seems if I set phone into "do not disturb mode" , the GCM disconnects after certain time , however if I disable "do not disturb mode" , it seems keep connection alive for longer time (since yesterday morning till night , roughly 14 hours without disconnection )

Try set the ping intervals for wifi and mobile to 2 mins and reboot. I am able to get push notification working after that. Tested on LOS with microG and Calyxos

Hi, @ex-git thanks , actually that's my current setting already :)

Everything should already be fixed on the latest version so I close it for now. Open a new issue if needed.
