Galaxy s4, growing increasingly slow. Probably upgrading to the iPhone 6+ because I like big phones. Maybe even a 6s or 7 if that's released near my upgrade.
I'm running a Sony Xperia z3 compact only got it a few day ago but it's great, massive battery life high performance in a small size running Android 4.4.4
Depends on what you do with it. Its perfect for drawing gaming media and that kind of stuff. Still, it fits into any pocket as long as you don't wear skin tight Jeans
If my thumb can't reach the top left corner of the screen easily, it's too big. Phones weren't made for both hands.
Provided that it isn't an ios device where the back button is at the top right my thumb doesnt have to be able to reach the whole screen but the phone does need to be manageable and personally i don't think i would find anything that is much over 5 inches comfortable to use. But having said that i need to say that its not really screen size that matters, Some phones have huge screens and huge bezels such as the iPhone6+,HTC or Xperia devices whereas others dont have much around the screen such as the Samsung,lg and Motorola devices. Its more the body size and shape that matters.
Xperia Z!! It's wonderful even though it's old; Battery life is pretty good (can do 2 days of use presuming airplane mode is active (for college)), has plenty of storage, can run pretty much anything (quad core with 2gb of RAM) and has a beautiful screen with a really robust glass shell. Dropped it several times (by accident of course) and it's obtained no damage (one of the corners where the plastic bevels the glass sides is slightly misshaped from where it bounced off a rock) and is by far the best phone i have ever had (Sony Ericsson W700 comes pretty close behind though). IMHO it's also one of the prettiest phones out there.
Note 3. I'm getting behind lol.. For the longest time I was trading up and up and up. S3 note2 s4 and now note 3.. This note 3 really does it all for me. I'm a full blown nerd.. I utilize as much of the phone as I can and no complaints. Never really lags on me at all. Really don't want to make the trade to a s5 they are nice just too common. Keep forgetting there is a note 4 lol.. Samsung quit making phones so fast. The LG g3 is a sexy phone. Been a Samsung fanboy for a while now but if the g4 is compelling enough I might have to end that reign
