S20 FE 5G - Playing games prevents apps from pushing notifications, have to restart device

Having played a game earlier, I notice after a couple of hours afterwards that I'm not getting notifications from many apps.

When my phone is restarted, either manually or automatically, the notifications all come flooding through. This is incredibly frustrating and worrying, considering that the apps include many popular ones like YouTube, Twitter and some messaging apps which I use to stay in contact with my family for urgent reasons.

I'm 99% sure this has something to do with the game optimization service, game booster and/or game launcher as its only after I play a game that this happens, even though I've troubleshooted by disabling the game optimization service via the game booster settings.

Does anyone know how this problem can be averted or fixed?

@AndrewL sorry to bump this thread again but I've further information on this and a more likely cause of this.

I've been monitoring this matter for a couple of months now and the issue was still occuring unfortunately, despite all the troubleshooting I've done in this thread to date.

I've since realised that the issue is now associated to my device automatically disconnecting from (leaving) a 5Ghz Wifi network zone (which has been my main Wifi network at home) and connecting automatically to a mobile data network.

To troubleshoot this, I've been manually disabling the Wifi before leaving the 5Ghz Wifi zone and allowing an immediate connection to mobile data without any further Wifi activity - this worked, but obviously it's inconvenient as sometimes I've an adhoc chore or two to do around the house hence there will always be a cavity wall and obstacles between my phone and the 5Ghz Wifi zone - I noticed that this was again causing a tug-of-war between the 5Ghz wifi and mobile data networks, and of course the app notifications issues reoccurred.

So on remembering that 2.4Ghz Wifi networks have wider ranges and better through walls, I then one day switched over to an available 2.4Ghz wifi network and on that occasion, all the app notifications came flying through.

I've since struggled to recreate this, but in any case have decided to disconnect my device from the 5Ghz Wifi altogether and stick with the 2.4Ghz Wifi - for the last few days now this appears to be working. Even when leaving the 2.4Ghz Wifi zone, the transition from the wifi network over the mobile data (and back) appears to be less problematic, if at all!

So there is the issue I believe - when the device transitions automatically between 5Ghz Wifi and mobile data, app notifications appear to be prevented from coming through on to the device. They don't get pushed to the device until the phone is restarted, or (if you're lucky enough) switching over to a 2.4Ghz wifi network.

Workaround/Solution - if the device is frequently in use in and out of the 5Ghz Wifi, it would be best not to connect to a 5Ghz wifi network. Instead connect to a 2.4Ghz wifi network.

Same happens to me on my S9+ (One UI 2.5), but don't think it has anything to do with games (don't play and game optimization is disabled, because all it seems to do is to intentionally slow down other apps). No idea what causes it.

Thanks for letting me know. It happens me 99% of the time after playing a game for sure. But I did notice as a once off the issue happening even though I hadn't touched a game. I presumed it was just a once-off, but based on your experience it doesn't appear to be the case at all.

I just got an update this morning so we'll see what happens from here.

Are you saying that getting rid of the game booster is the solution, and if so, how do you do it exactly?

Or are you venting? :face-with-tears-of-joy:

To keep this thread updated, I've learned that this may not necessarily be a fault of the game, game launcher, game booster or game optimization service. Rather it appears to be just the battery management by the device (for sure it's possibly due to the managing of the game services which put the battery management under pressure).

So I've since done some troubleshooting - on the apps which weren't pushing notifications until a device restart, I've changed the battery settings on each of the apps from Optimised to Unrestricted.

I'm hoping that this resolves the matter; if not, my next step will be to add each of the apps to the "Never sleeping list" inside Device Care > Battery > Background Usage limits. I'm really not sure what the difference is between this and changing the apps' battery settings to Unrestricted.

@daherlihy: Please can you try opening Game Launcher > Tap the 3 lines in the bottom right > Game Booster > Block during game > Notifications, and toggle this option off to see if this helps?

Already troubleshooting with this but I can assure you that Notifications are not blocked in the Game Booster settings. Indeed I do get notifications during game time from various apps.

Just to stress that this has nothing to do with notifications in-game.

And the issue doesn't appear to be exclusively related to gaming afterall - yesterday I opened a game in the morning afterwards - no issue for a number of hours as I was still receiving notifications. But then in the afternoon I step outside to collect the kids, leaving the wifi and entering mobile data. It was a few hours after this when I returned back to my home wifi that I realised that I hadn't received any notifications! So I restarted the phone and boom ... they all flooded through.

So it might now be something to do with the network management on the device, as well as any battery management.

@daherlihy: It might be worth checking Settings > Advanced features > Bixby routines, to see if you have any routines set up that might enable Do Not Disturb, or disable notifications under specific conditions. If the apps are web based, try heading to Settings > Apps > Select an affected app > Mobile Data > Allow background data usage > On > Allow data usage while data saver is on > On.
