Is it just me or is the touch response on the 5 not as good as previous models (4, 4s, etc.). I always remember my previous iphones as being very accurate when it comes to touch response. But I have been getting so many false positives/negatives on the 5. Everything from the keyboard to buttons in games/apps. Clicking icons on the homepages seems to be ok, but everything else is out of whack. Do you think my phone is defective, or do you think this is just an unfortunate consequence of the in-cell touch display?
