AT&T

Best phone I've used so far... Does everything better than my last phone which was pretty good for nearly 3 years (Nexus 4). This phone fits my specific needs very well. I drive a truck and do delivery work. This phone is my Audiobook entertainment, Google Maps navigator, Link to my home office texting machine, Customer contact phone (Bluetooth : LG T-One) and I'm not afraid of dropping it or pulling it out in the rain. A touchscreen that works when wet is a big big boon as is a camera that shoots excellent documentation pictures in nearly any light condition.
My complaints are very minor:
-Power-on with home button. I carry phone in cargo pocket in my uniform pants and flexing my leg pushes the Home button sometimes. Without a pattern lock enabled I wind up "butt dialing" all sorts of stuff. I've yet to find a way to disable this without rooting. (This is the first phone I have NOT rooted: I don't own it, yet...)
-Bloatware: Samsung has a few useful enhancements - maybe 5% of the Gig they add to the OS. AT&T has NONE that I would ever use since EVERYTHING they offer is done better by applications on the Play store. That's the bad. The good is that you can "Disable" most of this crap and let the phone run a bit faster and longer on a charge. The bad is that you can't remove them without rooting (see above).
This has been a GREAT phone for me over the last 13 months and I consider myself a "power user" fairly savvy about Android and the millions of things we can do with these devices. I -highly- recommend this phone if it meets your use case.
