I would like to try out the 4.7 inches on my Note 3. I'm thinking about downgrading screen sizes. The 5.7-inch is a bit too tall. Is there an app or a picture out there that I can bring up on my phone to see if my thumb will reach the top? My biggest complaint about my Note 3 is that I have to use two hands when I want to click anything at the top--not too convenient!
