It seems that if I hold the iPhone in one (left) hand, so that the palm kind of "cups" right below the speaker, it seems to be much louder and more pronounced than if I hold it without my hand there (ie. typing with both hands, nothing below speaker). The difference is very clear, the "clicks" when typing, for example, come out much "brighter" and crisper with my hand there. Without it, the sounds seem dull and hollow. I guess my question is, could some of you please try this out and see if it makes a difference on your phones or if there's something wrong with my phone in particular?
