Description
A gesture lockscreen replacement that offers both convenience and security.

Imagine this scenario:
A guy picks up your phone.
What's the first thing he'll do? Turn it on of course.
He presses the power button... no response. Presses a couple other buttons and touches the screen... no response.
What's the first thing he'll think of? Phone's Off. Battery's Dead.
It wouldn't occur to him that the phone is actually ON, but pretending its off.

Features:
-Two methods of unlocking
--Gesture Mode
--Key Combinations
Both offering an incredible amount of security
-App launching from lockscreen
You're able to create gestures for ANY app and launch it from the lockscreen. Please be advised that if you use simple gestures for these, it places your device at risk more
-Activate Settings from lockscreen
Need to turn phone to vibrate? Normal lockscreens requires you to unlock the phone, then unlock the lockscreen, then pull down the status bar to press Volume. Now, just do a volume down gesture, its safer too
-MugShot
For Android 2.3+ devices, there is front camera support to take pictures after a certain amount of failed attempts at unlocking

Issues:
-Certain devices will have their screens turned off if Display brightness is too low. The Setup screen will try to take care of that. So read the instructions, and email me if anything.

I should probably address the issues that some users are having with uninstalling. Void Lock can not be uninstalled after you have set it as a Device Admin. To uninstall, go to Settings, then find Security, find Device Adminstrator, and disable it.

Now, if there's any questions or suggestions, email me

This version is free, but still the full version. Differs from the paid version because of the ads, but DO NOT WORRY, ads will only appear after a successful Unlock and only once every 2 hours.
Sorry, but... I need to eat too. However, I don't want anyone to miss out on the lockscreen because of price so at least now there's an alternative way to get the lock?

Comments on Void Lock for Android

★★★★★ Great app This is a great app, works great especially for a beta. If you have problems with set up, read the directions! I would like to see the set up buttons look like actual buttons rather than pressable words.
★★★★★ Backup unlock Setting the "button configure" is your backup way to unlock your phone if the program doesn't recognize your unlock gesture (which it wont because the sensitivity is to high to start, but you can change it) so pick something simple like press the Volume Down button 3 times the combo should say 25 25 25. So when the phone looks broke just push the Volume Down 3 times give it a sec and it will start up. IF YOU ARE GOING TO LOCK YOUR PHONE MAKE SURE YOU PICK A COMBO YOU CAN REMEMBER!!
★★☆☆☆ Cool in theory but.. SGS2 CM7 setup doesn't work. Used setup app and when it tried to detect brightness level it turned my screen off. Hit where start button was and it did nothing. Power button brought me to my normal lock screen but when I unlocked it was black and relocked my phone. Had to reboot to clear it and get back to my home screen. Uninstalled for now. Will follow dev and see what happens.
★★☆☆☆ Crap!!! Pour menu! Very cheap interface. I waste my time with this app and after i have a lot of problems!!! I cant uninstall and after i made this, i cant lock my phone like before. I lock the phone and the screen still wake....!!! I NEED A GOOD APP, BUT NOT THIS! Very DISSAPOINTED!
