Samsung gt b5512-How to put screen on without pressing power button.

view story

http://forum.xda-developers.com – i have own samsung galaxy y pro duos GT B5512 and question is that could anybudy tell me about is there any other way to unlock the device without pressing power (when screen goes off) button, i mean to say like samsung galaxy y s5360 where we can press home button to stay screen on? If after rooting device is it possible please tell me. My idea behind asking this Q. Is that after pressing power button several time once it goes out of use. If we can use another button to awake screen from sleep mode it's better. Like any nokia phone does not lock screen or keypad itself, when we open menu or w (HowTos)
