iPhone 4S keyboard issue!

Ok so I have an iPhone 4S 16gb black for verizon and I have recently noticed some mistyping issues with my keyboard I have gone to Apple to no avail and my issue is that when I'm typing using almost any app I get a lot of cross talk on the keys is this normal? For anyone who doesn't know what that is its when the key you meant to type actually types the key directly next to it. Example: if I try to type "fox" its comes out "fix" or "quick" come out "quivk" because the key next to the o is i and c is next to v now many would say im not hitting the right key but i know that to be false because i can actually see the input drift over to the adjacent key. It also misses letters as well. Any help is greatly appreciated. I have noticed on only a few other devices but it seems hit or miss. Or is this the lack of the keyboard not being able to respond fast enough or accurate enough to differentiate between the keys I dunno. Random I know but please help because apparently Apple couldn't.
