low sensibility of the touchscreen, sometimes
this is my very first post :)
I have a new iphone since a week, and i noticed this issue (or better: i don't know if this is an issue...): sometimes, the answer to the tap is not immediate.
For example: in the image gallery, i double tap over a pic to zoom, then, double tap again to resize and nothing happens (or, sometimes, appears the upper/lower nav bars). Double tap for a third time and, finally, the pic resizes.
Same thing with the sms / browser charachters magnifier: to get it appear i have to tap stronger for more times....
many thanks in advance!
