[Greenify] Lusty Rugnuts:
I've quieted Greenify. I used MyAndroidTools to disable the following for Greenify:

Content Provider:

com.crashlytics.android.CrashlyticsInitProvider

com.google.firebase.provider.FirebaseInitProvider

Activity:

com.google.android.gms.common.api.GoogleApiActivity

com.google.android.gms.tagmanager.TagManagerPreviewActivity

Broadcast Receiver:

com.google.android.gms.measurement.AppMeasurementInstallReferrerReceiver

com.google.android.gms.measurement.AppMeasurementReceiver

com.google.firebase.iid.FirebaseInstanceIdReceiver

Service:

com.google.android.gms.measurement.AppMeasurementJobService

com.google.android.gms.measurement.AppMeasurementService

com.google.firebase.components.ComponentDiscoveryService

com.google.firebase.iid.FirebaseInstanceIdService

com.google.android.gms.tagmanager.TagManagerService

That Tag Manager Service and Tag Manager Preview Activity are worrisome...

So Tag Manager is yet another way for Google to track your every move... in apps and on web pages. It's almost a backdoor to your device, since Tag Manager can be used to remotely change what it tracks and when. Google is getting awfully malware-y, which is why I've worked so hard to make it so I can completely kill all Google components on my phone and the phone still works... and the Google components stay killed until I start them (without the necessary modifications, Google Persistence kicks in and restarts the Google components, which is also very malware-y... Google is a service provider, they shouldn't run unless the user wants to use their services, and there should be an interface to disable (or uninstall) any functionality the user doesn't want.). Further, the user shouldn't have to rely upon changing settings on Google's servers, while leaving the Google components running on their phone... that means we have to trust that Google is abiding by those settings... does anyone believe they are?

I've uncovered instances on this very phone where Google is less than honest in abiding by settings... another is their GoogleOtaBinder, which disregards the Developer Options setting to disable Automatic System Updates... the only way to turn off Google pushing a new ROM (without consent, without notification) and rebooting the phone (at midnight each night, without consent, without notification) is to edit a file such that GoogleOtaBinder can't authenticate with Google's servers.

You'll probably also find an app in Settings > Apps called 'Tag Manager'... I got rid of it long ago.

Google Tag Manager / Tracking Pixels and Tags

package:/system/priv-app/TagGoogle/TagGoogle.apk=com.google.android.tag

To get a list of packages installed on your system, in an Administrator-privilege command prompt on your computer, with your phone plugged into your computer via USB and set to 'File Transfer' USB mode, type:

adb shell pm list packages -f

Here's the list of packages I've removed.

{UPDATE}

I've also found the following:

The file:

/data/user/0/com.oasisfeng.greenify/app_google_tagmanager/resource_GTM-KN73P2

contains the following:

Component Display Name:

com.xiaomi.mipush.sdk.PushMessageHandler

alibaba.sdk.android.push.AliyunPushIntentService

com.igexin.sdk.PushService

com.tencent.android.tpush.service.XGPushServiceV3

org.android.agoo.client.MessageRecieverService

com.baidu.sapi2.share.ShareService

"MessageReceiverService"? PushMessageHandler? What is being pushed to our phones?

Further down, because I've completely neutered Google Analytics, it reads:

.analytics.disabled.exception.NoSuchMethodError true

{/UPDATE}

Greenify is also using the real 'adid_key' content in /data/data/com.google.android.gms/shared_prefs/adid_settings.xml, although I doubt they're in on Google's nefarious scheme to trick users into thinking they can reset their Advertising ID, while tracking them with a non-changing GUID (Globally Unique ID).

There are two keys in adid_settings.xml... 'adid_key' and 'fake_adid_key'... pushing the "Reset Advertising ID" button in Settings > Google > Ads changes 'fake_adid_key', but 'adid_key' never changes and is propagated to many other apps.

Further, I tried to uninstall Greenify (I'll manually set up device_idle_constants to mimic what Greenify did)... it's never had Device Administrator privileges, I disabled Usage Access, uninstalled the XPosed Framework 'Greenify Experimental Features', then went into Greenify's settings and disabled all that was there... but when I went into Settings > Apps > Greenify, there isn't an "uninstall" button, just "Force Stop" and "Disable" buttons. There's no way to uninstall it from within Greenify itself, either.

I booted into TWRP Recovery Mode, went to /data/adb/modules, deleted the module for Greenify, and when I rebooted, Greenify was gone. All that remained was to wipe it from the Dalvik cache.
