Do you like use the physical home button more often than the capacitive Setting button in your Samsung Galaxy S3? Personally, I do. I do not like to use the physical button as it take me more energy to pressing it ^^ If you feel to find a virtual replacement button for the physical button, you may not have it right now and I do not able to find a good app to do that too. The only option is to swap the function of the physical button with other buttons. Full credits to aydc, from Xda who has created the method to switch the function of Home & Setting buttons in SGS3 i9300.

I hope you are delighted when you see this post. But you may feel sad if I tell you the modification only can be done with the rooted SGS3 ^^
