Samsung Galaxy S8 Android 7.0 and up Stopping Network Traffic

Question

I'm working on an app targeting a Samsung Galaxy S8 running Oreo or Nougat that requires constant network access in the background. The app needs to send UDP packets and access user GPS location at regular intervals at ALL times, regardless of app-standby or doze mode. I know this is not standard, but this app will not be on the Google Play store, and this network activity is mission critical to our app's functionality.

I am referencing this document for development purposes:

https://developer.android.com/training/monitoring-device-state/doze-standby#understand_doze

and have made my app Oreo compliant by using startForegroundService and startForeground as described in the video below:

https://www.youtube.com/watch?v=Pumf_4yjTMc

I have added the below code to opt out of battery optimization as well:

    Intent intent = new Intent();
    String packageName = this.getPackageName();
    PowerManager pm = (PowerManager) this.getSystemService(Context.POWER_SERVICE);
    if (!pm.isIgnoringBatteryOptimizations(packageName)){
        intent.setAction(Settings.ACTION_REQUEST_IGNORE_BATTERY_OPTIMIZATIONS);
        intent.setData(Uri.parse("package:" + packageName));
        this.startActivity(intent);
    }

Additionally, I have turned off all battery optimization and app monitoring, and for my app checked allow background data usage and allow app while data saver on. I've also set the Wi-Fi to "allow while sleeping". I have seen the CORRECT behavior when debugging and testing for app-standby/doze using ADB as described in this link:

https://developer.android.com/training/monitoring-device-state/doze-standby#testing_doze_and_app_standby

but when I actually unplug the device and continue running the application, I do NOT see the behavior that was shown when I emulate unplugging and doze/standby. Eventually, the network activity stops for the app running in the background, even though the foreground service notification is still showing that the service which sends the UDP packets is still active. This makes it very hard to debug since I cannot force whatever state is causing this bis the adb like the docs suggest. It also makes me suspect that this is a Samsung issue and not an Android issue since I feel that I've complied as best as I know to the Android background execution standards.

When I'm able to examine the system logcat after noticing a network outage, I still can't find any indication of what's going wrong, and upon plugging the phone back in to debug, I can confirm my service process is still alive. Here is a snippet of the logcat that contains the last UDP message my app is able to send before it simply sends no more (at 07-09 12:10:17.206 23046-23107 in the below trace):

My main questions are:

Is there a reason why I would have see no issues while testing for doze/standby while debugging with ADB but see issues and behavior changes after unplugging?
This app functions correctly, with all background network activity persisting for a Nexus 5X with Nougat. Is there a reason the app wouldn't be working on an S8 with Nougat when it does function as intended on the Nexus 5X?
Is there a clear definition for Samsung Galaxy S8 app management somewhere that might describe the behavior I'm seeing? Maybe it's possible that the "Samsung Experience" doesn't actually kill services but it does do some other magic like simply snuff the network activity whenever it wants. If this is the case then I don't know about it.

Thanks for taking the time to read and for any help! If I can provide any other specifics let me know in a comment.

Galaxy devices have given me a lot of problems with this sort of stuff. Even if you turn off all of the battery management stuff it seems to put your app to sleep anyway. — BShaps, Jul 09 '18 at 18:27
@BShaps yea this is exactly what I'm experiencing right now. Feels good to hear a similar experience. Do you know if there is any definitive description/documentation of this behavior? — ThePartyTurtle, Jul 09 '18 at 18:29
For anyone experiencing this problem still, I ended up having to ignore battery optimizations, implement my service as a foreground service, AND secure a CPU wakelock, which as far as I had read, shouldn't have been necessary but it did turn out to be the case. — ThePartyTurtle, Jul 17 '18 at 15:48
did you find a solution, i'm having the same issue with a samsung phone? — 124697, Jul 23 '20 at 15:49
@code511788465541441 I actually sort of addressed my own issue in the comment above. You just reminded me of this open question though, so I'm going to submit that comment as an answer and accept, for the sake of anyone else that cruises by this post. — ThePartyTurtle, Jul 24 '20 at 19:52

Go to Device Maintainance in Settings then tap Battery, If you haven't already added your app in ''unmonitored apps, then add it.

Alternatively, Tap the 3-dots menu and Turn off App Power monitor. Maybe that puts your app to sleep.

Hi Updesh. Yes I have already listed my app as an unmonitored app and turned off the app power monitor. – ThePartyTurtle Jul 09 '18 at 18:24

I posted this in a comment sometime ago, and a recent commenter reminded me that this question is open and I figured I should post and accept as an answer what worked for me:
