Everyone use their smartphones to go on the internet or to watch videos and not to call anymore, so bigger is your screen better will be your experience for those usages.
Something doesn't look right about that tape measure and the phone in that pic to me. Not sure what it is but it just seems...off. The way I'm seeing it in the pic, phone would be over a foot tall, or maybe over 8 inches. Just doesn't look right to me. I don't know.
I prefer 4... but I can only dream. I don't get the world and it's fascination for big *** phones.
