Thinking of trying a custom rom. Couple of questions.

Hi all. I have a SM-G930F on the latest UK BTU Nougat firmware. I have a fair bit of standby drain probably about 10% overnight with or without AOD. I also find the home button to respond kind of slow when closing apps but I dunno if that's just me. Anyway the whole point of this is can anybody recommend a stable ROM that would make the phone run smoother and have less standby drain?
The thing with the home button I mean is if you press it it can take a second or so sometimes before closing the app. I never seen my Xperia Z1 or Z2 do that like they close as soon as you tap it.
Also would triggering KNOX affect anything else on the phone apart from it just saying 0x1? I use the fingerprint sensor in apps also so I'm not sure if a custom ROM will disable that.
Sorry for all the questions and thanks in advance if anyone has any help to offer.

The home button delay can probably be fixed by disabling s-voice and/or double tap home button for camera
For standby drain, try clearing caches from recovery
Other things can be disabled without root using Package Disablers from the play store

Thanks. It does seem to respond faster with the camera quick launch on which is kind of awkward since I like having that option but I'll put up with it. Holding it launches Google at the minute. I'll have a look at the other stuff and see what standby drain is like from there too.

Seems (With MM anyway) there are two quick launch settings for the same function, Applications > camera and in the actual camera settings too
For me disabling them both makes it faster than just one of them, although when you toggle one, it should toggle the other too, but doesn't appear too
EDIT - Correction, it appears 3 times, also in Settings > Advanced features
Not sure I see the need for the same function to be in three different locations, unless they're copying Windows 10 now

Possible Solution For Notifications

I think that the notifications that don't appear when screen off is caused by the restricted background data that lenovo has pre-checked. Just untick the option ​shown in the picture to allow background data for the application you want. Tell me if this will work for you

Also turn off battery optimization for this app.
Settings->power management->battery optimization and then choose all apps instead of not optimized, find the app you want and disable battery optimization

I have done this also :crying:. Upon re-opening Messenger while on data, it shows 'Waiting for Network' then 'Connected' and all the notifications come through. Ive also tried disabling Doze to no avail. Notifications work fine when on Wifi so not sure what the problem is, looks like a software design problem made by Lenovo. I might try Lineage in the future.

I find that when I return home and phone gets WiFi while pulling in drive I suddenly get Gmail notifications so seems mine is same.

The only way to fix notifications I've found that actually works is to disable doze via adb shell.
Sadly this fix needs to be reapplied every time you restart the phone making it a bandaid for a gunshot wound.
It feels like the OnePlus 3 all over again...

Install this app...
This app should work very well...

OxygenOS/Adroid Pie keeps autokilling or refreshing background apps

So ive been having this issue recently where the phone will turn off apps that i want to run in the background and i cant figure out a way to fix it. The biggest issue is with AdGuard. When im using it, the phone will randomly kill the background process and the vpn will turn off allowing all the adds to come pouring in. I've mentioned this issue on the oneplus forums and nobody there seems to know how to fix it. I'm considering moving to a custom rom once i find one that works well with my needs but first i want to make sure this isnt something that i can fix on the stock rom since i dont really need all the custom settings that come with custom roms. Im running the latest stable 9.0 pie/OOS.
Thanks for any help in advance

When you open the recent app tab press on the 3 dots right above the app. The press lock. That worked for me

did you set it to not optimize in battery settings?

under battery optimization. disable advanced optimization.

Ive enabled the lock and it still clears it and i have to reopen the app and re-enable the lock
Ive also set background process limit to be unlimited in the developer options. I cant think of anything else to do except maybe install adguard as a system app???? I've seen that this problem occured with the OP5 as well and people modified build.prop to increase the process limit, i've since found out that the option thats in the build.prop file is gone in the OP6 so i cant do that either. This is driving me crazy and i dont even know if its related to the os or the kernel.

Android 9 (Pie) - Bugs after Update

Hello to the XDA Dev Community.
I'd like to start a threat with bugs after the Android Pie update on our devices.
1. Bug:
Camera App forgets the "volume down key" binding. Means, when double pressed in standby mode the cam is not started.
Solution: Sadly this works only temporary - start the cam app and exit or close. After that the above mentioned shortcut / quickstart works for a short time in standby mode.
2. Bug:
This one is still not repaired: when switching to black mode (to lower the battery consumption) one can not see in the apps overview which of the apps are deactivated - the letters are not visible. When you have the white menues, the term "deactivated" is quite readable. (This bug is existent from the beginning with Android 8 - i chatted on this topic with the customer service of Huawei last year but that guy had no blink of an idea, he sounded very unexperienced.)
My Device:
Unbranded, European version, yesterday received the update.
Wonder if anyone experienced same difficulties and perhaps if there are solutions to this.
Have a good day

Whenever you do a significant upgrade, do a factory reset. This cures most problems, people need to start doing this rather then moaning.

Quite a good idea - but I am long enough into the smartphone scene (since Windows CE and Mobile) to know well that "factory reset" is unfortunately not the magic solution to all problems as some would like it to be...
Of course factory reset is done. Problems are still there, and to be honest - we would have not awaited it as a solution to both bugs i mentioned above a priori, would we?
Well besides I recognized another bug or feature(?)
3. Bug (or feature?):
The native mail app no more shows contacts pictures left to the associated mails.
Does someone know if this is somehow configureable?
Thx in advance

Hi,
found next bug.
4. Bug:
Fast double tapping the "square button" works inconsistently.... It should switch between the two last apps in the tasklist..... May be it has to do with a little time delay / time lag in reaction of EMUI9/Pie... I have the slight feeling that the OS is not that fluent as before (under Android 8)
I hope that is it....

That AI thing in the left most corner in the camera APP is not working, it is the same button as the one you see next to the search bar when you swipe down for searching. I think it used to be some kind for scanner or products? Now the button just flicks and does nothing.

Working on my device, I had to confirm the consent before... Maybe u clicked it into the background?
Update:
I deactivated the corresponding Huawei app (HiVision), now it fully disappeared in the cam app and on the lock screen (formerly found at the bottom when you swiped from down to up... The list where the flashlight, calculator and so on appear)

Hey there,
Have you tried to go to battery optimisation (go to settings, hit the search bar on top and start writing "optim" and the first one), then search for "camera" and disable battery optimisation. It solved the problem for me.
I've found that the Pie is more aggresive overall with killing the background apps. I've had to add way more applications (than on droid 8) to the "disable battery optimizations" and to "app launch" (in settings, battery, app launch -> set applications that you want to survive on the background to "manage manually")

Thanks, will try your idea!
OTA Update: Against all info - the update was found by manual search in the standard system settings. As it was found I parallely checked HiCare App - NO updates were found, it was a joke!
So maybe also check this way, do not trust HiCare alone.
Update:
Found and activated the performance mode (as you said - battery settings). Sadly no change in performance of the app-switching.

Disabling the battery optimization for the cam app is the solution. It works even after restart of the device without starting the cam app before!

Hi,
It helps a bit, but still inconsistently working, even after restart of the device. I also tried to put EMUI into the AppAssistant app to enforce it, but the app is not selectable (guess it should be HiStart, EMUI or something like that)...
Only solution atm is to SLOWLY double-tapping the square button.

Update on this issue, I tried to clear data and cache which brought me back to give consent again and all but it still didn't work. What I did was disable it, which tuned it into factory default and then enabled it again and wolah, it works again. Thanks for informing me about the app name btw, would have been impossible without it. HiVision.

Calendar invites for office365 meetings cannot properly be accepted on the device. it sends the originator a 'not supported format.ics' file - rather than actually accepting the meeting.
Pretty stupid tbf. I'll look to move off the standard mail client i reckon

My P20 Pro (C782) finally prompted me to updated to Pie today, but having done so I'm experiencing choppy / clipping / stuttering audio when connected to my Sony WH-1000XM3's (using LDAC codec). This wasn't happening on Oreo at all.
I've done a factory reset, but the issue persists. Happens throughout whatever's playing (Spotify, Tidal, PocketCasts, YouTube) and is especially noticeable when pressing the power button to activate the screen.
Any ideas?

Anyone else having problems with the volume rocker?
I can't slide the volume to the left to get multiple profiles. Isn't it possible with the pie update?

Wonder if the volume rocker is not vertically orientated in Pie. Mine is working good, sliding down goes to silent. Above the slider is a button for vibration, sound and silence.

Sounds to be a limitation by Huawei software...
I also recognized following bug (Android 8 & 9):
If I configure any mail account to "manually" in the native Huawei mail app, the app still looks for mails after a time when i only open the inbox....
Same situation when device goes into ultra power saving mode or automatically powers off because of low power....after return to normal state or reboot after charge the app now looks on all mail accounts for new messages itself/automatically. This happens when WIFI was on before powersaving mode or power off. As soon WIFI is available at startup or return to normal mode aforementioned situation occurs.... Can be avoided by canceling WIFI connection to the server/router....
That is indeed annoying!

And what does sliding to the side do?
It should show all the profiles like media, alarm and phone volume? No?

I noticed that the homescreen shortcuts, that arised if you press and hold on the Phone Manager icon, were removed. Too bad, would link the power mode to homescreen. Even better would be a shortcut in the Quick Settings.

Inconsistent notifications

Hey guys,
So have the Chinese version with the Chinese ROM still.
I have noticed that sometimes apps no longer give me notifications unless I open them.
For example, if I do not open Gmail it does not auto download the emails and does not notify me of new mails.
WhatsApp does not always tell me I have new messages unless I open it etc.
I have tried to check the power settings and such and cannot find anything.
This happens regardless of whether I am on mobile data or WiFi.
Any ideas what may be causing this and how to stop it? I'd like to get my notifications as I receive new WhatsApp messages and emails etc.

I can't find the source or any helpful guide to fixing it, but I swear I remember seeing something about how MIUI prevents some notifications from reaching you by default for some reason.
I'm pretty sure there was also ways to get around it as much as possible, but another solution is to flash a custom rom.

Hmm, I did a quick Google and saw something about battery optimization but could only find MIUI optimization.
Will keep looking, hoping the global ROM will fix it though?

For emails, I suggest turning on auto sync. Maybe other notifications will get fixed too. Do note that turning on auto sync will result in more battery usage.

It is and has been on from the beginning. So that's not the cause.
Still experiencing this issue. Had full signal earlier and had a friend try to call me 3 times in WhatsApp and only got the notifications when I opened WhatsApp.

(I'm assuming most of the settings in MIUI 8 are still available in MIUI 10)
MIUI is VERY aggressive when it comes to controlling apps running in the background (when in this phone is completely unnecessary given the massive battery), I would do 2 things to fix these problems:
1) Look in "Battery and Performance" > "Manage Apps battery usage" look for the app you want notifications to work properly select it and select "no restrictions", or you can just turn off power saving mode completely and every app will show notifications properly
2) Look for a setting named " about this phone" or something similar, in the "MIUI version" tap 7 times till you get a message "you are now a developer" .
Go back to settings, select "additional settings" and look for "developer options" , go to the bottom and disable MIUI Optimization.
These two actions should fox notification problems and also RAM management, you apps won't be suddenly closed when running in background.
Quick note: after a few years, when battery starts showing it's age and your phone starts rebooting randomly , turning on MIUI Optimizations might come handy, it will work similar to iOS, slowing the performance a bit and limiting the amount of background processes to lower the battery draw, your phone might run a little worse, but it won't have random restarts.
Again, I currently use MIUI 8, so some names might have little variations, but the steps should be similar.
Hope it helps and sorry for my english

Oh yeah, and also turn on sync
Edit: just read your reply, keep sync on then

Try these settings

Here's a possible solution.
Open Security App > Manage Apps > Select app
> Enable "Autostart"
> Notifications > Enable "Show notifications" and "App icon badge" > enable the following toggles for all notifications found under NOTIFICATION CATEGORIES > "Show notifications", "Floating notifications", "Lock screen notifications" and "notification light" (also "Sound" and "Vibration" if needed).
> Battery Saver > No restrictions
In order to prevent MIUI from killing specific background apps you need to do this:
> Open each app separately > Go to "Recents" menu to see the apps running in background > long press on each app separately and lock it by tapping the lock icon.
> Reboot the device
Please report back and let me know if this has solved your notifications problem or not.

Thanks guys, I will give the above a try and see if it works and if so which setting(s) fixed. Y issue.
Will report back once I've had a chance to test it all.
