I can't tell due to the fact my flip case is huge bigger than a chest coat pocket.
If I go naked its fine quite nice not too big TBF its just me, but I'm sure the note2 screen was bigger and I found mucking about with that one okay aswell. I think the Koreans got it right because my assumption Asian hands aren't as big as Americans and they designed it well as you can in all fairness have multiple smaller screen folders placed anywhere on the phones main screen, shink it to size so you can text or type with just one hand. I find I use the speech recognition software on the note4 as you can actually use it properly and not give you random settings. Access is not a problem at all.
Only thing I would have changed was the rear speaker for the front, but TBH the sound is fuller or more bass than any fronted mounted speakers guess is the design of it was to amplify or compensate for the rear location.
One annoying thing is the camera when you take pictures holding the focus button too long it snaps about 20 pictures in one go as I can't tell when to let go due to the auto focus? I think its my fault as I'm used to holding the take button for my other phones to focus, as this phone all you need is to just press once and its auto focuses and then takes the picture?
Haven't made a vid yet, I'll try and post the quality soon as I can, still playing about
Need to dig out the camera take some pictures of it and upload it for you guys!
