"Unlock your device with a jedi hand move"

Reviewed by / Jun 05, 2012

ScreenWakeUp uses the proximity sensor to lock and wake up the screen

Some devices that today would be called "low-end" devices had some issues with the lockscreen button. Perhaps due to that ScreenWakeUp came up: an app for unlocking without touching any button, just moving your hand over it or when taking your device from the pocket.

Although it was probably its main use, it's still an app that can be useful even if your lockscreen button works properly. Lock and unlock quickly or even tease your friends making a jedi hand move over your phone to unlock it. You can lock the screen by long pressing on search key or by covering the proximity sensor on the top of the phone for a few seconds (or putting it in your pocket).

NOTE: Before uninstall you must release the lock admin (run ScreenWakeUp and select on "release lock admin").

The app works great, and it's highly configurable: set lock in call, lock in landscape, auto-unlock, lock screen after X seconds... and much more. The only catch: it can be unlocked sometimes by accident. Anyway, recommendable.

Developer's original description available here
ScreenWakeUp uses the proximity sensor to lock and wake up the screen. It run as a service and it will restart automatically on boot.

WARNING: BEFORE UNINSTALL YOU MUST RELEASE THE LOCK ADMIN! (run ScreenWakeUp and select on RELEASE LOCK ADMIN)

You can lock the screen with ScreenLock application (it's not a widget), a long press on search key, covering the proximity sensor on the top of the phone for a few seconds (settable) or simply you can put the phone in your pocket (I've noticed it can fail if the tissue of pocket is opaque black, I think due of how the proximity sensor works).

The screen automatically wakes up (or unlocks if enabled) when you take the phone out from the pocket or you move a hand over it.

The program is event driven (don't uses CPU cycles to check sensors), but the phone needs to stay in PARTIAL_WAKE_LOCK mode to permit the wake up. The CPU doesn't go into sleep mode, so after a few minutes (settable) the lock will be released to prevent battery drain. You can read more about PARTIAL_WAKE_LOCK here: http://developer.android.com/reference/android/os/PowerManager.html

Don't be afraid about consumption of proximity sensor, it's really low (0.045mA on my atrix).

Permissions required:
- WAKE_LOCK for turn on the screen
- DISABLE_KEYGUARD for unlock the phone automatically
- MODIFY_AUDIO_SETTINGS for check if a headset is connected
- RECEIVE_BOOT_COMPLETED for restart automatically at boot
- VIBRATE for vibrate on screen lock

No internet connection needed, no ads, no privacy risk.

Known bugs:
- Sometime the auto unlock option don't works
- Sometime the proximity sensor stops to work when the phone is connected to PC (you must restart the phone)
