[Q] [B506] Background apps get closed and can't receive notifications

Hi all,
Has anyone experienced this with B506? Some apps like Telegram or WeChat get closed in the background just after a few seconds and then if someone messages me I don't receive the notification until I actually open the app (which completely defeats the purpose of the notification...).
Is this just a problem with my phone or has anyone else experienced this?
I know it's the app that's getting somehow closed because every time I start for example, Facebook or WeChat, I see the splash screen (which is only shown the first time an app is started).
Thanks for any help!

Are you allowing it to run in the background, and allowing it to startup at boot?

That's the thing, ever since I flashed B506 I lost that setting in the menu where we had the security options and could choose what runs in the background and what doesn't... I thought this was removed by Huawei on purpose. Do you still have it?

Yes, I still have it, and you should too.
Do you have the Phone Manager app? All the options are there.
In settings, Protected apps is the setting for the background apps.

Ugh, I'm so stupid! I froze the Phone Manager app (as well as a bunch of other Huawei apps) without realizing this one is actually needed.
Thanks! It works now!

Multitasking Issue

Do Anyone have issue with app closing too quickly in background even less than a minute??
I am noticing it for past few days. When i switch chrome with any other app and come back within a minute then chrome page reload itself. This was not the case with my previous device Moto X2.
Also faced issue with mini militia app when switched to whatsapp for few seconds, the app restarted when came back.
Any help will be grateful.

Yes, this phone has very aggressive memory management. It kills background tasks too quickly.
Looking under memory settings, I have used 85 apps in the last 24 hours and the maximum amount on RAM this phone has used is 1.6 GB...seems the RAM usage never hits more than 2 GB as the phone keeps killing apps.

Noticed mostly in Chrome, page reloads even if switched app within 30 seconds, no other heavy app running in background.
Faced with Mini Militia game too, app reloads if switched for like 10 seconds or more.

Delayed Whatsapp notifications

Hi guys i just installed Crdroid pie rom, is a nice rom i really like the customization, the problem is that my notifications for Whatsapp are delayed, don't really know if it is the same for other apps. I got the doze for google play sevices module for magisk, i removed greenify because i thought this app was messing with this, i removed whatsapp from battery optimization, but nothing works. To clarify, i had all this configuration on Leedroid rom and never got this problem. Any idea on how to solve this?
Thanks

You would probably get better assistance from the Crdroid ROM thread. Asking here you would need someone who has that ROM to help. You will have better luck with that on the Crdroid thread

Did you by any chance restore a whatsapp backup from Titanium Backup? I know when I did that, I would miss tons of notifications and had reinstall whatsapp and restore chats via the app's own backup and restore function.

No, i just installed from play store and didn't did the backup from the app. Now i did a hard reset but i think that the problem still there, this time i didn't install any mods or change any config.
Is so annoying, the messages are delayed to 5 or more minutes, and sometimes they doesn't show until i open whatsapp.
I've seen this app as optimized in the battery configs: com.google.android.gms.setup
Sorry guys but im such a noob

Sounds like maybe you don't have the app set to allow background data usage..?
I don't use the app myself, but that's what I would check.
Go to*Settings > (may be under network and internet)Tap Data Usage > Tap Mobile data usage > Select WhatsApp*> Tap Background data to enable if unchecked*(path may vary slightly depending on OS version and rom)

i tried it before but don't change anything. I looked on stanby apps on developer options and whatsapp appear like "EXEMPTED" other apps like the messaging one appear like "ACTIVE". In background check whatsapp doesn't show, would it has to show the app or maybe change the stanby status to ACTIVE? Thanks guys

I've trying a lot of things, and i get to the conclution that is there's no problem with battery optimization because i disable Doze by adb and the messages still delayed. I think is ram managment, a very aggressive behavior of it, whatsapp just don't work in background, gets killed by system just a few minutes after being open don't know if it is caused by the rom or by pie. Gonna try another pie rom to see if that solves my problem, if not, i'm gonna have to back to oreo

How to prevent Android from killing apps?

So, I have this issue, where most of my apps can't stay in recent apps overnight. They all get killed, all but 5 I have noticed. I did the battery optimization thing for all apps I use on a daily basis. I have edited build.prop file and added sys.keep_app_1=com.whatsapp and so on for the rest of my apps. I also did that in the local.prop file. None of it worked. How to prevent my phone from killing apps overnight?

If you are rooted you might try the app LSpeed and use one of the build in RAM profiles.

I am rooted. OK, I will try it. Thanks. It shuts my app very VERY aggressively. For instance, I was watching some youtube video yesterday, and in the other app I was searching for some products and was going back and forth between YouTube and Google Chrome, and every couple of times it restarted YouTube app, even though I was using it 2 minutes ago.

Both youtube and chrome are resource hungry apps, that's why it keeps reloading.
I guess your device is 3 gb version as mine.

I have the 4 gb version as well and I don't face such an issue, if nothing works try factory reset, absolute solution :good:

Tried it already, didn't work. Try leaving 10-15 apps opened in the evening, and see in the morning if they are still in recent apps. And tell me tomorrow.

Well, then you probably need a custom rom. Android One is known to be optimized for dumping non needed tasks. You could try to disable battery optimizing for the apps you would like to stay alive.

Tried that too, didn't work.

My previous phone was 2Gb running android 6. Now i have a mi a2 life 4Gb and it is OK except for 2 games.
Apparently there's some AI that learns what you use but after many weeks no change.
Most apps open pretty fast. It's only these 2 games that I run daily. Annoying to have to wait for them especially since the old phone was able to keep them cached.
I tried the low-memory config (magisk module) but it didn't help. I guess android has changed its algorithm. I'm resigned to it.

It's insane. What's the point of having 4, 6, 8 or 10GB of ram if you can't use it?!

Connect it to a monitor, install Taskbar app and SecondScreen app, enable Freeform windows and turn your phone into a mediocre PC. Assuming you can get all the resources back from OS's hidden service threads of course.

Facing the same issue
facing same issue specially after android 10 update. Change apps back and forth even in recent apps menu kills the app. My phone is 4/64.

Android 10 has a known problem. Rebooting helps. For how long seems to vary. I get a week or so, some people only get a day.

I had the same problem when I was unrooted during the Android 10 update crash. After rooting and installing Lspeed again, Android is not killing apps anymore as I set these settings

Battery drain issues

I've been experiencing battery drain issues with random apps even after shutting off permissions for those apps and shutting off background activity. These apps have also been added to battery optimization.
I've noticed this happens when I open the app and then shut them down, by swiping away from recent apps screen - verified by reopening the app and it never is in the memory and reloads. But they still continue to drain the battery in the background (as can be seen on the screenshot with battery drainers). Facebook is a usual culprit but not the only one, there is generally a few of them as you can see there are some games too. This pretty much keeps changing to different apps every now and then. I feel I'm doing something wrong which is really causing this drain.. every now and then. Any suggestions / opinions?
Thanks!

To add, I'm on the latest firmware with May security update (the one has been persistent throughout before and even now) ans not rooted.

How many time you do it ? Because it consumes less battery to keep them in memory than to reload all the apps every time you use them.

Just a pointer re Facebook.
Take a look at your System apps in Device /Settings /App category
Look for Facebook... and you will see other 3 x Facebook related
apps also listed ..!
You shut Facebook down but the Facebook Services, Facebook App Manager.. etc...? is still running and suckling battery.?
See my screen snip.
I most probably don't need to remind you that Facebook,
has over the past years, been fingered/known, to drain battery
.
My solution, which you most likely won't l "ike"
is to temporarily disable Facebook and the other Facebook related system apps.
Uninstall the one small Game or both??
and see if there is a improvement ?
Good luck.

I meant I've tried both strategies. Shut them off by swiping them away, letting them be and also shutting off thr app's setting to run in background. Nothing worked really.

That's the issue, Facebook doesn't really bother me but the games (or other apps like Twitter or tiktok or Instagram) do. And it's not always Facebook or these specific games. It's different each day - any apps I more frequently used that day continue to stick there consuming power. Every day it's a different set of apps. But wondering why stick causing a drain!

yes ,
Firstly ,
over the years ,i have been a few times, in similar "position" than you, re apps and battery draining .!
I know it's very frustrating ..annoying .....
and in the end i always ended up doing a factory reset . !!
I use a cross section of a different "set " of tools eg BettterbatteryStats ,Wakelock Detector lite ,Gsam Battery etc . ( all ADB enabled) to try and pinpoint the culprit ..
Unfortunately ,the permutation/reasons can be many ??
eg You installed and uninstalled an app and "something " eg System settings got corrupted .?
You disabled /freezed ,an System app and it has an knock on effect .
You did some mod /hack or maybe a sideloaded app thats causing it ..?
App that you installed that's badly coded .
It also could be that when you did an OTA to latest firmware that something/system ,got corrupted..?
Bottom line ,
You sitting with a very irritating/frustrating issue .
Your options is either to live with it ? or try and find the culprit ?
or doing a factory reset .?
Yes, i know you most likely, don't favor a factory reset.
As stated i always ended up doing a factory,on the spur of the moment !!!
Then doing a clean install from scratch ..a few apps at a time .......
Anyway it's your choice .??
Good luck .

Thanks buddy, you make some really good points. This is the first time ever that I haven't rooted the phone or done anything to disrupt the default OS. All I've done is the ADB permissions required for the GSAM Batteey app tk be able to pill detailed info.
I'm thinking if there's some way to reset all permissions and reconfigure them as the apps require? That has fixed things for me in the past.
Factory reset isn't an easy option for me because of RSA apps configured on the phone otherwise I've got to go through a few calls to get access - sorta irritating.
Hopeful something works but until then I'm letting it be lol.
Thanks!

I understand above if you say factory reset is an issue.!
I have a app call Bouncer paid (Play Store) installed on my device.
Don't think there is a free version, cannot remember, as I've had it for a while.
It basically controls your app permissions.
You can configure it to automatically remove permissions after using relevant app.
Also you can reset permissions.
It might help you.?
You can Google around a and see reviews.
To give you a idea, look at my screenshot.
Sorry, can't give any links, as it a paid app.
Good luck

Purchased the app. Kinda handy, but even after rule once set, when you come out of the app, you need to remove the permissions (the overlay window on top requests for removal) - that sorta adds work opening / closing apps.
My battery issues have improved immensely by putting the Facebook app in deep sleep. Battery life now is pretty decent.

check find my mobile.apk and samsung internet browser.apk if at all installed official apps from apkmirror etc the uninstall that apk and go through galaxy store but in galaxy store dont update findmymobile.apk

I suggest you take another look at your Bouncer settings.
You can auto remove it.
I had it on this setting but, change it to lock notifications, as i had better control.
Also remember to back up your Bouncer settings.
If ever you make a mistake you can just import you permission settings.
I forgot to do this a one stage and had to redo over Bouncer 200 apps.. Permissions...!
Otherwise if not sure as dev of Bouncer, for assistance
Good luck
