Smart Screen Off it's a simple and light app which uses the Proximity Sensor built in your Android smartphone to turn the screen off and on automatically

Requirements: Android 1.0+


************** REASON ****************
I decided to code this app when I bought my Galaxy Nexus: this device
doesn't have any physical button on the front screen. Being a quite huge
phone, it's quite difficult to press the "turn off" button every time I
wanted to turn it off and on. So I needed a way to turn the screen off
every time I put it into the pockets and off when removed.
**************************************
************ HOW IT WORKS *************
The app itself is a toggle button, to switch it on just press the App Icon. Then every time you put the phone into your pockets the screen turns off.
If you put the smartphone upside down on the table, the screen turns automatically off.
NOTE: It doesn't lock the screen (just like in a call)

************ REQUIREMENTS *************
In order to use Smart Screen Off, you need to have a phone with Proximity Sensor (nowadays every smartphone incorporates one).
