3.5" to 3.7" is perfect. Anyone that wants a higher screen has either poor eye sight or no computer at home.
Have the original desire which is 3.7 and any bigger than that is much harder to manage with one hand unless you have big hands.
If you are holding your phone with one hand and cannot touch the 4 corners of the screen with your thumb comfortably then in my opinion the phone is too big.
Anything bigger than 4 is too big.
Just measure the reach of the lower tip of your thumb. If you need to stretch to operate the other side of the screen, if you need to flex your palm... it is too big ... for your hand. So it will probably be unpocketable in pants your size. Again clear sign that people's desires easily verse in not pratical territory. Beyond 4 inches is a sure path to "carpal tunnel syndrome" class action lawsuits. That is why Sony-Ericsson released phones with the same architecture and resolution but different screen sizes.
martin, 15 Mar 2012Speaking about diagonal display sizes without mentioning different screen aspect ratios is jus... moreMy opinion is that screen size should not exceed 4.3 inches to maintain a compact body. Now that said it is also dependent on the hand size...for smaller hands 4 inches is the max and for bigger it can go to 4.3.
I agree at 3.5 to 4.5 for Smartphones. From 5.0 to 10.1 for Tablets & PhoneTablets
i like my galaxy note 5.3 inch screen ... but if there have a only 5 inch should be nicer
Nick25, 15 Mar 2012i like my 5'3" inch NOTE screen.the only thing i don't like is that you look stupid making/taking a call if you are not using headset.
that being said, a headset on galaxy note is a must. unless you don;t intend to use it a a phone (just being funny here)
