Touch Screen Less Responsive on Right Edge with iPhone 5

So I've been having this issue with my iPhone. I actually had it replaced because of this and have the same issue with the new one.

What happens is that it seems like the right edge of the screen is either intermitently or always unresponsive. This is noticeable when trying to toggle the On/Off switch in the settings like for Airplane mode. There's no problem on the left side when I press the round button but it doesn't respond when I press it on the right side.

I also notice it in Safari when I try to drag a page near the right edge and the upper right hand in Maps doesn't respond to double taps. In general, it is difficult to select small buttons.

The last thing is that, when I try to use the keyboard, I'll try typing in an M and it will press Delete instead. Needless to say, this is annoying, particularly when I'm trying to fill out a form with an email address and the keyboard doesn't have a .com button. In fact, the keyboard buttons tend to skew ever so slightly towards the left side of the screeen in general. I have relatively fat fingers, so I tried using my fingernails and my pinky, and still had the issue.

Has anyone experienced anything similar to this? There were a few threads that touched on this but they weren't that specific. It seems like a design flaw rather than an isolated incident, as it appears to be present on all iPhone 5s that I've tried. I'm not sure if it's a software problem or if the new manufacturing process is flawed. In any case, it seems like something Apple should resolve.

I realize it's kind of a small thing but it really hampers usablity. I'm guessing most people just assume that it's supposed to be like that but I guess I expect more from Apple. I know that it wasn't an issue on some of the Android phones that I've tried out. The only reason I got an iPhone instead of an Android device is because the App ecosystem is so much better on the iPhone, particularly for music apps, as I'm a musician but I'm thinking that I should just get an iPad for the music stuff and an Android device for a smart phone unless Apple wants to address this issue. I did contact Apple Care and the rep couldn't really do more than apologize and say that the issue would be recorded. My hope is that enough people complain about this issue they might do something about it; I'm not holding my breath though.
