Goal: Disable Samsung's Bixby or Microsoft's LinkedIn preinstalled app.
Standard approach (fails on many devices): adb uninstall com.samsung.android.bixby.wakeup (often returns DELETE_FAILED_INTERNAL_ERROR)
Extended key solution:
adb shell pm disable-user --user 0 com.samsung.android.bixby.wakeup
To re-enable:
adb shell pm enable com.samsung.android.bixby.wakeup
Solution: Suspension and disable-until-used are persistent. However, --user flags are per-session. Create an init.d script (root) or use Tasker with ADB WiFi to reapply extended keys on boot.
To truly wield adb app control extended key, you must understand five critical modifiers.
Solution: Some system apps are protected. Use adb shell pm disable --user 0 com.android.app first. If that fails, you need root or adb shell pm uninstall -k --user 0 (which doesn't remove the app but hides it for the user). adb app control extended key
ADB extended keys turn your computer into a powerful remote control for any Android device. Whether you’re automating media playback, building a custom accessibility tool, or simply testing how your app responds to hardware events, mastering input keyevent is a game-changer.
Start with the media keys, experiment with system controls, and soon you'll be scripting complex sequences that feel like magic—no root required.

Stay tuned for Part 2: "Injecting complex gestures and multi-touch events with ADB."
ADB (Android Debug Bridge) is a versatile command-line tool that lets you communicate with an Android device. While standard input (taps, swipes) and basic key events (Back, Home, Menu) are commonly used, "Extended Keys" refer to keycodes defined in the KeyEvent class that represent hardware buttons not typically found on a touchscreen device.
"App Control" in this context refers to the ability to manipulate a running application's state (e.g., pausing music, skipping tracks, taking a photo) by sending these specific key events via the ADB shell. Solution: Suspension and disable-until-used are persistent
