Test mode
The value set here is returned to other apps through a content provider. It can be used to disable analytics during automated testing. Since Android 11 apps can lose visibility of this content provider after some time or a reboot, so launch this app immediately before running any tests to make sure the permissions are freshly granted.

content://com.sengami.appium_test_helper_android.provider/
