HTC Apache one handed use

[SDellJunior]

So I'm new and maybe this post is dumb and you all are going to yell at me to search but I didn't turn up anything when I did so here it is:

What exactly do I need to make my Apache touch screen work easily for one handed use. I know I saw something about it but I've read so many posts I can't remember where it was. I'd appreciate it if someone could point me in the right direction or tell me what to do. Thanks.
