It happens so frequently, when I touch the screen it wouldn't respond as expected and I have to touch again, it's really annoying. Is it because of the screen protector? But it's by Belkin, which I suppose it to be the one of the best protector in the market. Or is it because it wasn't applied to the screen perfectly? I applied it carefully, without alignment tool though. Or should I peel off the screen protector now and use the phone without it?
