General :: IPhone 4S - How To Disable Lock Button

After having an IPhone 4s for two years i decided to switch to a galaxy s4 to see what it was like. My first touch screen device was a cheap rubbish MID rocketchip tablet running android 1.7. Every since then and seeing my friend using his HTC wildfire and how laggy it is in things like scrolling i always though iphone was better until i got the S4, realising that with the latest android scrolling was smooth (although can still be laggy at times but rarely) and with all its customization etc i don't like iphones as much as i did but don't completely dislike them just don't think i'd go back to one. That said i do miss some of the apps that i can't get on android.

Anyway whilst i love the galaxy s4 i found what you could say in a design flaw but it's also a good design at the same time. Samsung as positioned the lock/power button on the right side of the phone. Which ok is more natural when holding the phone and other phones are the same too but i've noticed a problem although it could just be me. Whenever i play a game or use any app in landscape mode i've found myself accidently pressing the lock button so i have to make sure that i haven't placed my finger on top of it as where it's placed is natural for my fingers to hold the phone in landscape mode. As i say might just be me that can't hold it properly. Anyway i was wondering if there is a way i could disable the power button in landscape mode so that if i press it, it won't do anything. I was thinking of using tasker but doesn't seem to be away to disable buttons.
