Help Screen sensivity


Hi guys I am looking some help or information my GS III. I just had my HTC Sensation replaced with a GS III which had lots of freezing issues that could not be solved by T-Mo. However my concern with the GS III is that the screen sensivity is very high, meaning that most times I do not have to touch the screen to have a selection made, I just have to hover my finger over the screen then it happens. My question is, is there a way to adjust the screen sensivity or this is a problem with this phone? Any help or information are welcomed. Thanks guys.
