As to Huawei mate 9 series, it is quite obvious that the phone screen flickers and stops responding when disconnected from internet whith mainly whatsapp still running in the background.
Until issue is properly addressed it is advised to stop internet hungry apps before getting disconnected from wifi or mobile data.
This process can be done from within settings>battery>power intensive apps.
Only there whatsapp can be shut down.

How to get "reactivate setting" in Huawei Device (Development)

Hi folks,
I stumpled over the setting "reactivate system" which whatsApp holds on Huwei Devices. I am developing a chat app, which gets killed everytime screen goes off. I followed all instructions for the new doze mode in Marshmallow. This is the last option that I can imagine that causes my problem.
Does anybody know what I have to do, to make my app show this setting?

I think you should probably change the power saving mode from smart to performance.If this doesnt work go to apps then select your app then battery ( make sure you are not on charging) then slide on the keep running after screen off. worked for me sometimes. also try to allow all the permissions.
Huawei is messing with its customers badly, this is actually very bad considering they have become the third largest manufacturer after samsung and apple.

Mate 9 with runkeeper

Hello, I am actually using Mate 9 Pro, but I thought that more users here so I wanted to ask you one question.
I yesterday noticed that when I try to log my run with runkeeper, the app always closes when I quit it. It doesn't happen with any other phone I have (Nexus 6P and OnePlus3T) nor doesn't happen with other run trackers. But Runkeeper is just unusable.
Is the same problem with Mate 9 also?
OT: Where did you buy the Pro ?
Same problem
I have the exact same problem with Runkeeper on my new Huawei Mate 9 Pro:
When the screen locks, either automatically or through me pushing the lock button, the tracking stops...
Mine was bought in Norway where I live...
Anyone?
There is a standard setting in EMUI in which apps default auto close when screen is off. This can be changed, but you need to get into something like Settings -> apps -> [Your App] -> Battery

No its not this since every other running app does work well. I just don't want to change to other app after using runkeeper for several years now

Huawei mate 9 vs runkeeper
I have a same problem with my huawei mate 9. Before I had Honor 7, and runkeeper always stopped with it too when the screen is off. So I think the problem is maybe with the EMUI...
I made the settings which you mentioned below, but doesn' t help.
Anyone, is there any solution?
I know it doesn't help but I haven't noticed any issue on my UK Mate 9.
There was a Runkeeper app update yesterday - check if you have the most up-to-date version.

I have the same issues with Huawei Mate 9 Pro and endomondo. Try changing the power settings for runkeeper in:
Settings->battery->power saving from apps->close apps on screen lock->runkeeper - disable
And:
Settings->apps->settings->special access->ignore battery optimizations->runkeeper->allow
I have done this and but still have some issues with endomondo.
Tried to install GPS locker to keep a lock on GPS while using endomondo even if I do believe it is a power issue.
But maybe it will work for you?
I'm on the B156 software.
I know this is less ideal, try converting to a system app and see if that works.

Same here but apps are dolphin browser, xe currency and stock message app
No solution?
Workaround is to use another launcher.
Thx for the tip,will try
I used google now launcher, but when choose app from opened apps, the screen will dim again. Waiting for fix with next update.

We reported this during the beta testing and it was ignored

I did clear cache of nova launcher,and since yesterday it is working normal
I think that's not a bug, it's power save function, same happens in stock dialer, stock sms app and Gmail
When it cant be control by user in a normal on/off way,then its a bug
I have a same problem with Chrome and SMS stock app.

The auto-dimming in email and Chrome happened for me in EMUI 4 and now 5.
I was told that it is a power-saving feature and cannot be turned off.

I didnt have this problem in 4.1,im going back
Hi, occurs this problem on to the build 380? Thanks.
Same problem here. Battery saver is off, auto brightness is off too. Any workarounds or word from Huawei?
This happens on all mobiles with emui 5
Mate 8, honor 8, Huawei p9, nova...

Really stupid bug that shows how poor emui developers are. Still in latest chinese developer rom, no sign that developers are even aware of the problem. Don't know how so few little people are reporting this, must be blind.
It should only happen when power saving mode is enabled like it did in older emui.
It causes so many problems. I have screen set to my preferred brightness then it dims so much when I open browser that I have to increase brightness every time. The only work around is to use 100% brightness all the time, then it does not dim the screen but this just a stupid waste of battery and bad for your eyes indoors.

It's not just email and chrome either. It's any web browser, nearly all system apps and a small few other third party apps.
Another issue that may not be a bug is when watching a movie the screen contrast increase dramatically and causes crushed blacks, does not happen on honor 7 with emui 4.

Notifications fixed?

Hi,
I had an Honor Note 8 and notifications any came through if apps were open in app memory, or if they had a widget.
Adding them to a whitelist/ignoring battery optimisations did not work and notifications were blocked and only came through when you opened up the apps.
Is this fixed in the Honor Note 10?
Could any users please test by closing all open apps from app memory and seeing if notifications come through for the following apps:
eBay
Etsy
Amazon seller app
Google Hangouts
WhatsApp
Facebook messenger
This is the only thing holding me back from buying this phone. It doesn't look like a Global version will ever be released and I need to know if the Chinese ROM still kills notifications.
Thank you
Hi buddy
I have noticed when my screen is off for a bit then when I open WhatsApp loads of notifications come through.

Even with those option it does not work on note 8. We had to remove an APK called powergenie from the system to stop it from killing app even if those app are whitelisted.
Huawei power management is too aggressive.

One year I used Note 8 with Nougat and no problem with Power Management! Upon upgrading to Oreo system it automatically shuts down applications in the background, and it also does Note 10 ... ?
Phonemanager was the problem here on the Note 8. When i disabled that everyting worked great.
There are 2 settings that will totally minimize this problem (even Galaxy note 8 and iphones of my brothers are having this problem too)
but if you follow these 2 steps you will definitely minimize them as much as other phones
1. Settings/Battery/App Launch and set individual aps you like to get the notification to Manage manually
- turn all the 3 options on here (running in background , startups , and can be run by other apps) this will stop your phone from killing these specific apps from running in background
The second reason you don't get your notifications is because when your screen is off the Wifi will be disconnected first and then for a certain period of time , the system will also turn off your mobile data to save the battery as well. This means even if you have those apps running in background , you still won't get the notification because there's no internet connection....
So step 2 - go to Settings/Battery/ then look at the top right corner for the "gear" icon ,click ---- > Keep mobile data on <----- turn on option
(if you don't have mobile data plan and only rely on your wifi connection,well, you need to turn on keep your w-lan on instead )
Have fun and cheers

Thanks, but I did all of this on the Note 8 (when I had one) and it did nothing. All of my notifications were blocked. The only way to fix it was to remove the awful PHONE MANAGER app via the ABD removal method.
If the Note 10 is going to be the same, I'll have to pass. I just want a phone that'll work properly out of the box.
No problem with WhatsApp, messenger eBay and Facebook so far, everything comes straight thru.
I did however observe sligh delay with Gmail.
Even with Gmail widget active in the background emails come at least one minute later after sending from another device.

I am using the Honor Mediapad X2 and having the same notifications issue, please note that there exists a HIDDEN WHITE LIST within Phone Manager where certain apps like Whatsapp are white listed and allow notifications to come through whereas other apps such as Hangouts and email clients are not. Having said this, do not use Whatsapp as a test to determine whether the Note 10 has the same issue or not. I do not know whether the Note 10's white list now includes apps such as Hangouts as it is a newer device and so it may be more up to date.
For your test, try an unpopular app which uses standard GCM protocol, kill the app, put the device into DEEP SLEEP (screen off, etc) and only then see if the device wakes up and notifications come through, they should.
Please use the QUOTE feature when replying to me to get my attention. Thanks!
The problems that i had on the Honor 8 are not on the Honor 10. I get all notifications with no problems. Just set the apps in manual mode and select all 3 options in phonemanager -> startup apps.

Hi
I am sorry to disappoint you. On the Huawei Honor note 10 (EMUI 8.2.0 build 132) you won't receive notifications if the application is closed (not running in the background nor in the foreground), with one exception that I have found so far: WhatsApp.
All the settings you can modify only affect the application WHILE IT'S RUNNING IN THE BACKGROUND, that is, the app will keep running if the background and won't be killed if you disabled battery optimization for the specific app and changed the App Launch setting to "Manage Manually" with all 3 options enabled. However, if the application was closed by you or never launched after restarting the phone, you won't receive notifications even with disabled battery optimization and power management.
I am so frustrated, I don't even get reminder notifications from Google Keep notes app. The only workaround is to manually open all the apps you wish to get notification from when you power up the phone.
If anyone has a better workaround or has a different behavior than what I described, please advise!
Cheers,
David

David, plz see my post above. I believe there is a built-in white list which once we are able to decipher would be very happy

Hi,
Unfortunately I believe this is per design and not a bug (Huawei strict battery saving policy.
The only way to guarantee notifications is to open the app you wish to get notifications from and keep it always running in the background.
Read the article below, it explains down to the bit level why notifications don't work on Huawei phones:
Damn I cannot post outside links because I am a new user. So Instead, search Google for this:

Whatsapp keep disconnected

Hi Mate 30 pro fans,
I have weird issues, regarding whatsapp application. I will frequently disconnected while im idle or not turn on the phone for 5 minutes or more. Seem like EMUI keep killed Whatapp in backgroud. Does anyone have similar problem like me? For information, i already re-install the application twice, set special permission to disallow system to automatically kill the app manually. but the issue keep coming.
Thanks in advance guys!

2 things under settings u adjust. i solved mine via these 2
1) go App. under App launch. select "manual" and tick all 3 options for Google framework, account manager , huawei mobile services and whatsapp. i did that for google map too
2) again go App, under permission. select special access on the drop down list on top right hand corner. choose battery optimisation. i select whatsapp as well as those apps mentioned as above 1) and choose "not allowed" so that these wont be killed . Just adjusting 1) under App launch does not work. its the battery optimisation that kills the app after a while.
u need to perform these 2 adjustments so that whatsapp will continue to work behind .
this 3rd step is optional. I've also enabled locking whatsapp under the task it so that it won't be close even if i clear all app in the background. click on the square icon at the bottom most of the phone menu, scroll to whatsapp and swipe down to lock it. swiping up kills the app
make sure u enable data for these app.
hope it helps. i did it for my 5G set from china.
