After upgrading my Galaxy A51 from Android 10 to Android 11, it has started periodically (or randomly) killing my two XMPP client apps, yaxim and Bruno, despite both having a permanent (and visible) foreground service notification.

Ironically, the OS recognizes those kills as a crash and immediately restarts the app, causing a large amount of unneeded network traffic:

03-22 08:55:09.470  5028 10568 I ChimeraPolicyHandler: Killed on trigger2 : org.yaxim.bruno, freed: 34707, 10202[4548]:G2(0x20000) score=26,8(39 5 34707), pids: 4548 / stats: 4 / adjs: 200 
[...]

Even more ironically, it also keeps resurrecting (auto-starting) apps that I have manually force-stopped before.

The ChimeraPolicyHandler seems to be a job running multiple times per hour in the system_server process. ps shows:

system         5028   4601 12953324 266152 0                  0 S system_server

Hello, I think this supports the theory that in fact at least of the new issues on Samsung after Android 11 could be accounted to memory management issues. So IMHO Samsung did memory leaks in their Android 11 so the memory on your phone periodically runs out and this is a standard Android feature to kill processes to regain memory. We have seen such issues especially on Moto G phones in the past which were notorious for memory leaks. This issue basically does that all services get restarted from time to time on your devcie which causes performance issues and of course apps may not work properly.. this issue is on Samsung to fix IMHO..

I've seen the OOM killer in the past, but I'm pretty sure it wasn't advertising itself as "ChimeraPolicyHandler", and I can't find any reference to "ChimeraPolicyHandler" in the AOSP, so I tend to think this is some Samsung magic at work. It also seems to have some whitelist of processes / UIDs ("Skipped by uid"), but maybe that only really whitelists the system process.

In the app I work it is happening the same. I have a Samsung 20 with the latest Android 11 (security patch 01-03-2021).

I have a foreground service and I've already put the app (org.myapp.msg.dev) in Battery optimization ignored list. I don't know what to do anymore.

I would like to know how "ChimeraPolicyHandler" selects the app to be killed. Samsung should be more transparent in this aspect.

Hello, big thanks for the growing evidence on this issue.. Did you see https://issuetracker.google.com/issues/179644471 ? Does maybe disabling battery optimization on the device prevent the ChimeraPolicyHandler from killing the foreground service? Big thanks for all your feedback!

JhonHuGit commented Apr 14, 2021

I am not an expert, but from my experience, disabling battery optimization does't stop apps from being killed. Radomly, I get crash report.
And would you mind modifying the content of samsung on DKMA website? Because it does't do the trick at all. In fact, maybe there is no way to maintain apps running in the background.

@JhonHuGit Many thanks... unfortunately we are not yet sure if this is a bug on some Samsung devices (API level 30) or if this is really intended behavior by Samsung... At least on our support requests from Samsung users in wast majority of cases on API 30 the DKMA link resolves the issues. But we are updating the https://dontkillmyapp.com/samsung page with more details on this and with a link to this thread..Many thanks..

Two days ago, Samsung rolled out a new update, patch level "April 1st" , One UI 3.1. Since then, my apps weren't killed a single time. To me, this looks like it was a genuine bug and that it's fixed now. Thanks to Samsung for listening to users and developers!

In my Galaxy S21, since february second update, this problem was solved, but in latest may update is this problem returned. Foreground services are killed. My own application and also another applications. This not kill application, but restarts foreground service (parameter intent in service onStartCommand() method is null). Notification for foreground service is removed and application must again generate it. Similar problem is in application GSam Battery monitor.

@henrichg big thanks for the valuable update. In some of my own apps when the service is critical to keep it I use an AlarmManager-based restarting of the foreground service. Nevertheless this can happen on stock Android even without ChimeraPolicyHandler.. actually when running critically low on memory Android will kill the foreground service and restart later on if STICKY with a null intent. Did you check in the logcat if this is still caused by Chimera? As I guess a memory leak is not an uncommon thing on Samsung devices unfortunately and it would cause similar observations.. Big thanks..

@henrichg
Copy link

Hm, I do not know, if it is caused by Chimera. Maybe yes. I must log it.
I'm using applications in mobile since buy it. Facebook, Twitter, Reddit, Chrome, GitHub, XDA Developers, Instagram, Google Play, Galaxy Store, F-Droid, GSam Battery monitor, Autentificator, Google Pay, .... Not any new application is added to mobile.
Also in my PhoneProfilesPlus application was not any news.
Memory usage in mobile is (by me) good: 5GB from 7.5GB. Average usage 66%.
For PhoneProfilesPlus it is 90-130MB.
And yes, I know. If system restarts service, intent parameter is null. It is in API documentation. But by me, it is not due to low memery.
Service is STICKY, is started with startForegroundService() followed by startForeground().

Hm interesting. Problem was going away. After change of Samsung battery optimizations settings:

  • enabled: Device care / Battery / 3-dot menu / Auto optimize daily
  • enabled: Device care / Battery/ Background usage limits / Put unused apps to sleep
    -- Device care / Battery/ Background usage limits / Sleeping apps: Mi Home
    -- Device care / Battery/ Background usage limits / Deep sleeping apps: 0
    -- Device care / Battery/ Background usage limits / Never sleeping apps: 0
  • enabled: Device care / Battery/ More battery settings / Adaptive battery

But "Optimize battery usage" for PPP is set to "Not optimized".

Interesting. :-)

Greetings,

I have the same issue on my good old Galaxy S5 running Lineage 18.1 (Android 11). The problems of Sleep as Android being killed while running in foreground started after the upgrade from Lineage 17.1.

I've noticed two things:

  1. The problem goes away in airplane mode (or turning off wifi and mobile data)
  2. The Goole Play Store now is radically killing all kinds of apps while searching for updates (not only the ones actually being updated).

So, just a guess that those two could be related. Prevent the Play Store from doing its thing by killing all data connections.

Regards,
Zy.

Hello folks, I have been contacted by Android Team recently and they are asking for developers willing to contribute tests as part of their CTS (Compatibility Test Suite)...

I have reimplemented the DontKillMyApp Benchmark as part of Android's CTS Verifier tool which is now in review as a pull request under https://android-review.googlesource.com/c/platform/cts/+/1799749

I would like to ask you, are there any devs who would be willing to help and contribute their tests to the CTS Verifier so that we can help Google put further pressure on misbehaving OEMs?

Big thanks.

Hi.
I can confirm that the issue with Android 10/11 killing foreground processes is still happening and not exclusive to Samsung devices.
I noticed the issue with an autoclicker app I've used for months. Then, maybe since july, it started closing misteriously after about 1 hour of un-attended use (screen on and device active). It happens on both my android devices: a Samsung S20+ (SM-986B) with Android 11 and a Huawei Media Pad M6 (SCM-W09) with Android 10.

I did assume that it was related to some new Android battery conserving intrusive policy but until yesterday I didn't get serious about trying to fix it.

I decided to unlock my S20+ in order to try some custom ROMs and see if the problem persisted. It does.

Then I found @petrnalevka about Android killing apps on samsung devices (https://dontkillmyapp.com/samsung, very informative, thank you).
I did follow all advise there on both devices, but the issue still occurs.

I have focused on just the one device for now, so I can do proper tests.

The thing I'm inclined to think now is that the issue is related to excesive App power consumption since I've noticed that if I load a script with, let's say, 1 click every 10ms, the app is closed so much sooner (maybe after 5 minutes) that if I test with 1 click every 100ms (maybe it gets closed after 1 hour).

I would like to investigate the android logs now to check who is doing the killing. I have to research that since I've never done it before, but I will update results here when I do.

Thanks all for the information and I hope we can get to the bottom of it and force Google or whomever to fix it.

@jurrabi many thanks for your investigation. I'm little skeptical that there would be a common mechanism across Android 11 and 10 and Samsung and Huawei. IMHO I do not think this is something in AOSP and I'm not seeing this behavior on my Pixel phones. IMHO it is more likely that those are two independent mechanisms as both vendors are problematic / or it may also be a memory management issue - memory leak as Android standard policy is to kill even foreground services if critically low on memory. But if you can investigate the logcat it would be great if you would share some hints on what is happening.. many thanks..

jurrabi commented Sep 9, 2021

Thanks foryour response. I'll share the logs. But first I'm gonna check if a can find a stable AOSP for my S20+ and try to reproduce the issue. I'm guessing if it does it would probably mean as you said an issue with memory management on the app itself...

@guptapurv

I am seeing this exact issue on all the Samsung A11 devices at my organization. They're on Android 11 with Aug 1,2021 Android security patch installed.

They have 2GB RAM and it happens quicker if I open other apps after starting the foreground service as compared to not doing anything after starting the foreground service so this makes me think it's a memory related issue which others have already pointed out.

Should we re-open this issue since it's marked as Closed?

Let me know if anyone has got any updates from Samsung?

Setting the correct wake lock is THE CORRECT thing to do, on any phone, for cases when the app must work in background or with screen off. The whole point of dontkillmyapp.com pages is that many device makers modify the system to kill or put to sleep, or otherwise stop the app working in background, DESPITE setting the correct wake locks.

I have an A71 and Tab S6 Lite, both running One UI 3.1, security patch Oct 1 2021. I use Sleep as Android on the foreground to track my sleep, and in the recent 2 weeks, I noticed that it got killed on both my devices.

My alarms don't go off on Sleep as Android and Google Clock, but the built-in clock app works fine. Sleep tracking does not seem to run when I check the app, but there is no notification that the app crashed, so I think it got actively killed.

I tried both the battery optimization and device care methods but they don't seem to do anything.

Signal is getting killed or receives messages at least 4 minutes late on the Galaxy Tab S7 FE 5G. I whitelisted it everywhere the battery was mentioned. It seems that I had to also whitelist it from memory management, but I'm not sure yet if this is enough, and as it turns out, it isn't.

AbandonedCart commented Apr 9, 2022

@Whatnoww A lot of issues with Signal are related to Signal itself, though.

I stumbled across this issue because I develop an app that runs exclusively on Z Flip 3 devices. The app should always be available through a foreground service. I have received three separate reports describing the same behavior. They have all said the app "randomly stops running and requires a full reboot to run again."

I have been able to personally confirm that the app was being randomly killed off. I was able to stop that (temporarily, read on) by adding the app to the "Never sleeping apps" list. What I found interesting is that the app randomly disappears from the list, either in the process of an update or simply after a few days. It would seem they are still overriding manual configuration.

Mgcripps commented Sep 3, 2022

There may be a solution if implemented please add to android 12 , One ui 4.1.

This has occurred to me and I have found this is usually implemented when restarting phone but not necessarily. I like too use my home network through my data connection to my cellphone I first make a connection to my phones data and start up VPN'S with credentials then login to then addhome wifi allowing me to secure both my devices as it should be able to detect added information at either point between the devices connected. But when they do this to me I usually have to input new credentials logged on to a browser in safe mode. Then logon to phone normally with data as a hot spot then use both data to Hotspot. Usually I have to pick a random location from phone then logon to other device and logon to VPN but using the fastest location to make connection there-bye tunneling connection between devices. When one of my devices is hacked this is my default response as I am unable to use my credentials. So, I don't know how simple this solution would be to implement but when someone logs you off of an app and doesn't allow you to logon again you could setup the website to recognize you have logged on under safe mode and then simply send a command to automatically log you on to your phone vpn under your default sellection as you have proven your credentials are proper and the monitor OS for any indication as to who has hacked your device to further the intervention protecting the app User from further being compromised.

Have been testing a foreground service App on Samsung A10 (Android 11) and Samsung A04E (Android 12) The Samsung A10 occassionally kills the App but it immediately restarts! This occurs when the phone is doing something else intensively ie when playing YouTube video's etc! No problems with the Samsung A04E. The A10 seems to have other bugs as well. The newer A04E is considerably better. Also notifications occassionally delayed on A10, but not on A04.

TEhala42 commented Feb 23, 2023

@Pleasantless I would like to know on the www.dontkillmyapp.com website on which devices following their recommendations helps to SOLVE the auto-kill problem vs not or only just makes the killing happen less often. And there should be 2 different ratings, how they behave on DEFAULT settings and how they behave AFTER trying everything possible.

There also seems to be difference between BACKGROUND services and FOREGROUND services. Samsung was highlighted with red text and given the lowest/reddest rating because of them also killing FOREGROUND services. I'm not sure I entierly understand that but some apps got around the auto-killing by creating foreground services and on Samsung THOSE are killed as well e.g. a Voice Recorder app I'm trying to use in background. Some say foreground services are restarted and I get different notifications, sometimes it says "Voice Recorder Recording has stopped", sometimes "Voice Recorder Recording" but in any case recording is actually stopped. GPS logging USUALLY seems to work but is rarely killed as well, Call Recording seems to have worked so far.

Are FOREGROUND services also killed on your other non-Samsung devices?
Thanks for sharing info

P.S. I'm also afraid of updating because in every Android update something has been broken that wasn't before or more "security by obscurity", playing Big Daddy for us. I saw somewhere that "Software updates are meant to break perfectly working systems".

After turning off the screen, after 2 hours the app is killed:
ActivityManager I Killing 32118:com.my.app/u0a283 (adj 200): BarTender

Rich968 commented Mar 9, 2023

Implementation of foreground services for Android 13 is the same as was for 11 and 12. I have foreground service running OK in all versions testing on Samsung A04E. The problem may be with the content of your foreground service. Try removing the active content and then see if the App gets killed. Under some circumstances my App was momentarily killed and then immediately restarted on a Samsung A10, but OK with the Samsung A04E
