I have tracked down the cause of my delayed/missing notifications to the FCM receiver not automatically re-connecting when I roam from one access point in my network to another with the same SSID. This behavior started after I did a factory reset and updated my 6T to OOS 10.3.2 from OOS 9.0.17 (whatever was the last version of Pie)
Does anyone know the setting to enable the Reconnect Manager for FCM? You can see the status by dialing *#*#426#*#* and turning on advanced view in the menu on the top right.
My notifications do not work when it is in a disconnected state. As soon as I turn WiFi off and back on the FCM service reconnects and I get all the notifications I was missing. I have waited over an hour and FCM never reconnects on its own.
I have searched on Google on how to enable this setting with no luck, I even tried the Heartbeat fixer apps for GCM but they do not enable the Reconnect Manager setting in FCM.
I have attached screenshots that show the logs and status of the FCM on my device.

The problem is that Background Data and Sync ignore the wi-fi policy meaning that the settings to disable wi-fi don't actually disable wi-fi, they just block applications from using wi-fi. The OS can still use it and it still drains power.
That basically means you can never disable wi-fi unless you go in and change multiple settings. The wi-fi policy when the screen is off is useless. Any toggle wi-fi widget you put on the page don't work.
Manually refreshing gmail shows 'no connection' - browser wont connect. But the OS can still get your email and download attachments. Relegating any wi-fi policy to a 'user stop function', not a 'data stop function'.
I have a toggle wi-fi widget on my home screen. I have wi-fi toggled off (also shows as off in settings) I *just* saw the widget flick on for a second, then flick back off. That's the Background data/ sync kicking in right there and that's my whole point.
Another point - if you have disabled wi-fi then turn it back on, it should be looking for the router and getting an IP address. It doesn't do that. When you turn it back on all it does is enable applications to connect. Meaning, when you disable it (via settings>disable wi-fi or disable wi-fi policy) all it does is make the software think you're not connected. It doesn't actually disconnect from the router.
It still shows in your routers wireless list (which it shouldn't if it's disconnected) and ping test will fail because it will refuse any incoming/outgoing requests that aren't from the OS (background data / sync)
If you wait for the background data/sync to connect, you can then ping your tablet and it will work. A security issue as far as I'm concerned.
UPDATE | May 05
An update. I can confirm that the wi-fi will never turn off for me. I have toggled it off and put it in airplane mode and I will still get email notifications.
Under battery power it even still shows wi-fi as taking 4% even though by all settings it is off.
The gmail application shows 'no connection'. If i refresh it, nothing happens. If i turn the screen off, eventually it will sync/connect and I will get email - even though I also have the wi-fi set to off when the screen is off.
So to sum-up - wi-fi never turns off. Ever.
You can help by testing!
Disable wi-fi
Set the policy for wi-fi to disable when screen is off
Go to home screen
Turn off the screen
From another location, send yourself an email
Wait for notification on your tablet or wait for about 5 minutes
Turn on your tablet, email should be waiting for you.
UPDATE | 12:15pm
On the phone with acer support and they confirmed this is the case. They started to explain about Background data and Sync and I stopped them right there. This isn't a settings issue, this is an OS/Hardware issue.
Going to the next tier.
UPDATE | 12:30pm
Everything is confirmed with tier 2 and for what it's worth, it'll be pushed further down the chain and looked into.
I had to clarify with them that the issue was with the OS/Hardware and it's not software. If the wi-fi is disabled and I can go into gmail and it show 'no connection' and i hit refresh and it wont get email, then open the browser and it tells me I'm not connected, then the software thinks the wi-fi is off.
The problem is that the wi-fi isn't off as far as the OS is concerned. It is still draining power and Background data/ Sync are still able to connect (and/or override your settings). This shouldn't be the case. The wi-fi setting should superseed all other settings. If i set the wi-fi to off, it should be off for everything and not be draining power. To me this means that the disable wi-fi setting doesn't actually disable the wi-fi, it just locks out software from using it... which is *not* disabling it.
Same issue here, have to get a widget to turn of the wifi. How can they oversee such simple things?
Also sometimes the power button just randomly lights up when its in sleep mode, it's a small light but very anoying if it's dark in the room (e.a on your bed stand).
Okay - Good to hear it's not just me then. But not so good in general.
If you're reading this thread, try it out. Set the wi-fi to disabled when the screen is off then email yourself from another computer and wait for the notification on your tablet. Or get a friend to email you a minute or so after you've turned your screen off (with wi-fi disabled on screen off)
You can reset the policy after.
If you get the notification then your wifi didn't disable while the screen is off like the setting is supposed to do.
mine is NOT giving me issues, but I have found that it can take up to 10 minutes for the wifi to go off. I just used ping to test it. In some cases it took a while but did turn off. My battery doesn't really go down at all when in standby with wifi off when screen off.

I've set the wi-fi to disable itself when the screen goes off but unless I disable sync and background data, the wi-fi still stays on when the screen is off and I can hear my email/IM notifications still.
Anyone else have this issue?
I mean, I think it's an issue. If you set the policy to disable wi-fi when the screen is off in the OS it should override any apps - I shouldn't THEN have to go and disable sync and background data as well otherwise whats the point?

Hi, I just ran these tests and unfortunately I can't reproduce your results.
When I disable wifi, I don't have any data connection.
As for wifi sleep, I don't know if it's a bug or intentional but it seems to put wifi into an extremely low power mode, but not necessarily disable it or turn it off when using the sleep policy.
As someone mentioned somewhere in this thread, it looks like wifi has some sort of 'cooldown' period until it turns the chip and process off completely.
I have used Wifi sleep and played Pandora and had Pandora play for hours until it finally disconnected.
The problem is that Background Data and Sync ignore the wi-fi policy meaning that the settings to disable wi-fi don't actually disable wi-fi, they just block applications from using wi-fi. The OS can still use it and it still drains power.

Hi,
My H990DS has been bothering me for a couple of days as WiFi turns itself on without any kind of intervention.
Turning it off manually or having the phone restart does not help. I made sure the latest apps installed make no impact.
Playing with Developer Options made no difference.
I am ready to Factory Data reset.
Anyone experienced something similar ?
Thanks,
My 918 always shows wifi active in GSAM's graph, even when set to "Never" under the "Wifi on while inactive" option in system settings. I ended up just downloading Leandroid from the play store and setting it to disable the wifi radio, and renable it periodically to check for push messages. Seems to work fine with doze and standby time has improved.
Under settings, location, three dots top right, scanning, turn wifi scanning off. It turns back on anytime you use wifi and you manually have to turn it back off each time.
Mine (918) does this all the time. Im thinking its a 7.0 thing. There has been a few exceptions where it has stayed off. In my case I drive through a busy section in town and it constantly connects to the 20 or so open wifi spots so I turn it off. Well once I pull into the garage at home its magically back on.
Maybe something to do with networks it recognizes, Xfinity wifi wreaks havoc on it as well.
As soon as I uninstalled the latest apps, the issue disappeared. Not a single exception in 24 hours.
I suspect a Sip Client had caused the problem.

What!?
That sounds utterly horific for the battery, nevermind privacy concerns. I thankfully haven't experienced anything similar myself, but I've only ever used custom ROMs so perhaps that's the cause. But that sounds terrible.
I think it started when I accidentally put the Wi-Fi setting panel/app into multi-window mode. I already had an app halfway at the top and even though it should filter apps that are not multi window capable, the wifi setting panel was available and tapped on it. It could not be placed at the bottom half though.
And/or I played with NFC tags and wrote my network onto a sticker then read it back.
Ever since, Wi-Fi is unavailable. The toggle just toggles the icon state, but no actual connection is made. When I swipe down from the status bar again, the Wi-Fi icon is enabled again. Second screen icon doesn't do anything. I can't get the list of available networks as it's frozen and empty. After a while it says "Wi-Fi isn't responding. Do you want to close it?" This seems to eat the CPU so much it drained the battery quickly. How to I reset this or bring back the normal behavior? Device is factory unlocked H990DS, 1 month old and not rooted.
Screenshots here
I tried:
Rebooting
Removing the battery and putting it back
Entering recovery with: adb reboot recovery (it didn't do anything just an icon with "no command")
Connecting via scanning my NFC sticker but it just freezes the connection prompt
Enabling hotspot (it doesn't turn on and cannot be configured, seems to use the same configuration app)
I experiencing one rare bug with my new Nokia 5 phone. There is Wi-Fi Scanning option in Locations settings, that allow to scan Wi-Fi networks even if global Wi-Fi toggler is off. This option turning itself off after 2 hours of phone inactivity. I think it is something wrong with deep sleep mode in the last updates for my phone. I need this option being on for better location quality. But I can't to find any solution to keep this option turned on constantly. For a while I use global Wi-Fi option enabled as a workaround. How can I t fix this problem? Or is it inner program bug and I should wait for any luck in updates? Thanks.
Nokia 5, Android 8.1.0 with December security patch. I tried safe mode, factory reset, but nothing helped me.
P.S. This issue is somehow linked to known bug with removed by Google menu item "Keep Wi-Fi on during sleep". Some people reported it wasn't worked even if turned "Always". In our device it is always on by default (and hidden).
This issue is not linked to deep sleep or doze mode. It is linked with Google Play Services and device administrators. I removed all updates for Services and problem was solved if I'm right. For it I disabled all two device administrators in Security settings (Google Pay and Remote Controls). Now I installed updates again. I will test further.
Unfortunately issue returned after Google Services update. But I found another solution. I disabled idle (sleep) mode using adb. And Wi-Fi Scanning work all time now.
Hi, I'm running a rooted stock Oreo (version 8.0.0) and I've just discovered that when I turn flight mode on, if I then turn wifi on, I get the pop-up message "In flight mode" and the wifi icon in Quick Settings stays a light blue shade but Wifi doesn't actually turn on.
I may be mistaken but I thought this was working last year and I haven't done any updates to the phone.
Anyone have any ideas how to fix this?
Kind regards,
Mack.
Hi, I'm pretty sure you can use this:
SystemUI Tuner - Apps on Google Play
PLEASE READ ENTIRE DESCRIPTION BEFORE INSTALLING
play.google.com
One of the settings allows you to tune Airplane Mode.
Just to update - I think there must have been some kind of data corruption... I did a factory reset and it all worked correctly again.
