I am having facebook messenger problems

Hi everyone.
My wife has an S8 and recently she has noticed that she hasn't been receiving notification on Facebook messenger.
Me thinking it was an easy problem to solve went into the phone setting clicked on notifications and found that the notifications for the app were all on how they should be.
Then I went into the app settings and checked there and everything was right.
Then I restarted the phone and it still wouldn't work.
Then I uninstalled and reinstalled the app and still no success
I even got my phone out an S7E and checked how the settings should look on mine and hers matched my settings.
All her other apps are working except this one.
Am I missing something here, because it doesn't make any sense why it's not working. I performed a stock flash on the device about a month ago to 3 software, so she could have wifi calling but I don't see how this could of affected this one app and none of the others.
If anyone has any suggestions here I am all ears because I am out of ideas.

Make sure that it's not being forced close by the S8's onboard memory manager... sometimes it shuts down apps and you won't get notifications. Double check in the battery settings (you can get there from settings or the swipe panel) to see if the Messenger app itself is active.

Hi people, I seem to have solved the problem.
I followed the suggestion and went to the battery setting. In those setting there was an option for unmonitored and monitored apps. When checking the list of apps that were in these setting everything was right, including the messenger app in unmonitered app section. I removed it from that list and didn't bother adding it back.
Tested.........and it worked....I even got other people to message her in different situtations and it worked and still works.....not added it back in to the list yet, as long as it keeps working I prob won't

Push Notifications - Don't work on mobile data

Not sure if anyone can help, or if it's been covered before but I'm a new oneplus 6 user and have scoured these forums, oneplus, reddit etc and cannot find a working solution to my problem.
I currently have no real issues receiving push notifications on wifi, however mobile data is different. Once the screen has been locked for a small period of time I stop receiving push notifications. When I wake the phone some will show up, some won't show until the relevant app is opened.
Advanced battery optimisation is off.
Individual apps I want notifications from all have battery optimisation set to "Do not optimise".
I have cleared the phone cache through recovery mode.
All notification settings for the apps are on, background data on etc.
There is no option for doze mode in developer mode to turn off.
I have a Tesco Mobile and a 3 sim card. The issue seems worse with the Tesco mobile sim card. The 3 one seems to work better but slowly reverts to the same issue the Tesco one has. I've tried other people's tesco sim cards and replaced my own but none have worked.
Any help would be appreciated, it's driving me mad.

Just to make sure, under Advanced optimization settings there are two switches which are "Advanced Optimization" and "Sleep standby optimization", keeping the latter off might be the problem. Though if they're both off, I assume that it's just the native Doze working to save battery

Yes both are turned off. Do you know of anyway to turn off this "native doze". As a football (soccer) fan, I want instant score notifications for games, I used to get these fine on my iphone 6 but now I have to wake my phone all the time to get them to come up, even then sometimes they don't come through for another 15-20mins.

Have you tried settings in Wifi preferences?

I've looked in there but can't see anything that would affect mobile data. The notifications work ok when on wi-fi. I've checked mobile data settings and there are no settings for the apps in question which would restrict data usage.

Is this happening to all apps (ex. social apps like twitter or whatever) or just the football app? If it's the latter it should be a problem with that specific app. While if it's the former case, It should be something system-wide, so I'd recommend doing a factory reset maybe?
Btw my phone performs the same as yours with the "sleep standby optimization" on, while it operates as normal with it off, so your case seems pretty hilarious :/

I've experienced on all apps, it's most noticeable on the football one as you can time the push notifications exactly so can tell when they're late but WhatsApp, facebook messenger etc both the same. It seems as if the device just goes into a form of heavy sleep mode after around 5mins of lock. I've tried a factory reset already and nothing changed. OP have advised me to try and reinstall the OS but I don't hold any hope. It's almost as if the phone cuts off all mobile data after 5mins of downtime.

If factory resetting doesn't solve the problem then reflashing the system likely wouldn't either I suppose.
I still have two options in mind that you may be able to try.
First option is to use apps like "Doze" or "Naptime" both on play store, and mess with those advanced Doze settings to try to disable the function itself and see if it works.
The other would be to try the new HydrogenOS P beta or other custom Roms such as Havoc and see if they don't have this problem.
If neither of these work, I really have no other ideas
But I think these are worth giving a try though

I tried the Naptime app but that required root and doze didn't seem to do anything.
I've now tried Android P beta. Exactly the same issue. Once the phone has been locked for a few minutes all updates stop. Once I unlock the phone I get flooded with notifications. So frustrated.

no idea dude sorre

I'm having the same problem

I have similar but different issue with a few apps that I don't use often.
The push notifications only come through the second I put my phone on charge

Which mobile networks are you on? I found the issue to be resolved when using an o2 SIM card instead of my Tesco mobile one
Edit: Since this I have tried again with an o2 sim card and it didn't resolve the issue. Leads believe it's an issue with my handset.

Since few days, i have the same problem here, i try severall things but no solution at the moment.

I also had notification issues. Then I installed the stock rom of this topichttps://forum.xda-developers.com/oneplus-6/how-to/rom-stock-fastboot-roms-oneplus-6-t3796665 and my notification returned to normal

my notification come onl;y when i turn my screen on -> https://forum.xda-developers.com/oneplus-6/help/notification-android-p-stable-t3849170

I have this issue and I can't understand why more people aren't complaining about it.
Don't suppose your apps are restored from some kind of backup?
EDIT: Okay, people are complaining about it: https://forums.oneplus.com/threads/push-notification-issues.451149/page-121

have this exact same issue on my note 8 with android pie on vodafone network and so far nothing seems to help or fix the same really frustrating.
did you manage to find any solutions so far ?

Mi Note 10 Lite, Global MIUI 11 ROM - Push notifications from Gmail Problem

That's a very frustrating one, very common 'feature' for all the Xiaomi bloatware. I thought 6 years later, they will finally fix the sync.
So basically, when the phone goes to sleep or at least I do not touch it for more than 5 minutes, the Gmail notifications do not get delivered unless I unlock the device. Sometimes even if I unlock it, the said emails do not pop up unless I open the app or manually click my Google account to sync.
Things I've done so far:
Check any sort of notification setting for the app itself and make sure I get the proper notification type. Also the app settings are all right.
Check the battery saver nonsense and make sure the app isn't limited in any way.
Check battery saver and make sure it is not restricting background usage for the app
Reinstall Gmail app using XiaomiADBFastbootTools
Remove and re-add my Google account to the device
'Locked' the Gmail app to the memory
Things I cannot do on this crippled Android version, but work for regular apps, are:
Set 'autostart' setting for Gmail. The app seems to be preinstalled and I cannot manipulate this option for it.
Your help is appreciated!

maybe you could uninstall the Gmail using XiaomiADBFastbootTools and later you install Gmail again from Google Play.

I'm having the same problem. I have to go into the app and refresh and so on.

Strange, never had such problems (with all apps) after configuring the data saver mode for the app. Gmail is working without a problem here

The problem seems to have gone away for the last 3-4 days, but I was mostly on data connection. No clue how. There were no system updates.
From time to time it gets stuck when I am on Wi Fi at home. Either never comes or is delayed a lot.
Most notably when the phone goes to sleep (more than 10 minutes of not touching it or not receiving any other notifications that might wake it up.

Have you checked the notification settings within gmail? Stock configuration is that it will only inform with important emails and not all emails. Maybe this is also part of the problem?

Install Nicecatch by Samsung. It'll log all notifications so you can view the source.

Thanks for the reply,just installed it today and waiting for the issue to occur again

Just had the issue again, have noticed a pattern this happens around same time daily, nothing shows on the nice catch app ,wondering if this can be network related ,this is driving me crazy

Just checking back again if anyone has any suggestions,i did a phone reset and didn't face the issue for a week,and now its back

Sounds like maybe the reset fixed it, but some app you're installing or some setting you're enabling is causing this. I know if I temporarily lose service (dead zone) I'll get the same notification sound as my text message.

I might be due to Galaxy store update. When ever an app gets updated from galaxy store i here sound. Try disabling notification for galaxy store and experiment...

Question Notifications not pushing

Hi all,
I have been facing a weird issue of notifications not being pushed (some apps) on my S22U.
It was bearable in the beginning but now I am missing notifications of MS Teams and other important apps. Which quickly turns it into a nuisance.
I am rooted with latest magisk, lsposed - zygisk.
I would like to resolve it without reflashing my firmware again. Any help is appreciated.
Few things I have tried.
Checking if the notifications settings is on of the app.
Checking if I have not accidentally enabled DND (which is off)
Restarting the device.
Googling if someone have similar issue.
Reinstalling the app.
Clearing app data.
Disabling and re-enabling the notifications.
Thanks in advance.

Make sure battery optimization is turned off on the affected apps & that you have data enabled in the background as well on each affected app.

How about in the phone's device care/battery settings? Is the power saving option turned on?
Just spit-balling here, but, I myself forget to turn it off (sometimes) on a new device set-up/after a factory reset. Guessing power saving option turned on could possibly affect timely notifications.....

Checked. Power saving is off. Appreciate the spit-balling, never know what will work.

same issue here, i hear notification sounds, but never pop-up message or screen wake-ups.
just beeps...no solution found so far

I don't even get the chimes. I have watch 4 too. Thought if not on phone it might get pushed on watch, but no luck there too

This happens to me with LinkedIn: I get notif sound, but no pop up and icon on top bar. If I swipe down the notification is there though.

I am not getting any indication, no notification in statusbar and notification bar and no notif sounds. Weird that it is happening on some apps. I think some magisk module might be culprit but not certain.
