I am aware that this have been discussed many times, however, if anyone can suggest some pretty quick, off the top of the head, answers, I'd appreciate it.
I currently use a Note 2 (dated now), and my carrier is T-Mobile. I'll pretty much be seek a no cost upgrade (but that's for me to work out). I'm not committed to Samsung or Android (although an iPhone would be new to me). My eyes are a little weaker now, than they were a few years ago, so clarity is pretty much a requirement now.
Thanks.
