I have created simple Batch file... *.bat

I can unlock Screenlock/Screensaver with this...

Tested on my S8600 with I9001 Firmware... because unsupported Hardware and Touch not working yet....

Also on I8150 tested successfully... because taken from I8150...

Here Log, which I have converted into Dec Values by my little brain... line by line...

I am using old Android Version, where only input text and input keyevent is supported...

I can't install Android 4.x during incompatibility on my GT-S8600 yet...

Best Regards
