I'd like to see an iPhone thats about 4.2". the 4" iPhone SE is a little too small, but much nicer for me to hold than the 4.7", and the 5.5" is right out at the size.
I've been recently using a 5c again and forgot how much i loved this design. if the screen were just slightly bigger, and slightly less border, it would be my favourite phone.
except for iOS >.<
I upvoted you, but really, 4.2" is too big.
4.1" is the maximum size possible for one-handed use, in my opinion, and even that's pushing it.
