I was able to run some of the settings hidden apps via ADB with ADB shell am start -a android.intent.action.MAIN "com.android.settings"
These hidden apps are actually some of the activities runnable via "secret codes". Since secret codes are various and some of them are also vendor/device defined, is there a way to retrieve a list of every secret code available on a particular device? Maybe from a manifest, by identifying the receivers, via some ADB commands, etc.
Thank you in advance!
