Samsung Galaxy S7.
I'm a Samsung fanboy now (Galaxy Nexus, S3, S5 and now S7 and a NotePro tablet). After hearing all my Android friends rave about their phones, the OS, the apps, etc. a few years ago, I realized their was a better mousetrap than the iPhone... and boy, was I right.
I was an iPhone user for three years and remain a happy Apple computer user. Note to all who are curious: Android phones and Apple computers play very nicely together. With Android File Transfer, I can move files back and forth with ease and don't have to mess with any unreliable cloud storage. Yes, I have an old-school mentality when it comes to that as I've heard too many horror stories about Apple's cloud, especially about how iTunes and Photos doesn't properly sync across multiple devices with the same Apple log-in... so I'm happily boycotting using it. And guess what -- my way works beautifully and easily.
Yes, the S7 has treated me extremely well the past couple of years. The OS is sweet, battery life is stout and the camera is just as fantastic as everyone says. The Google Play Store is terrific (it's kinda like the Mos Eisley spaceport... vast and diverse options... so sometimes you have to dig a little to find what works), but I always get what I need. I love how they have tons of apps the Apple Store doesn't while still offering all the apps that are in the Apple Store.
The S7 has survived drops without a scratch as well as splashes and dunks in both fresh and saltwater. Btw, Samsung offered up waterproofing and OLED screens YEARS BEFORE Apple... what does that tell ya? At the recommendations of the employees at the AT&T store, I went with the S7 and not the S7 Edge as I was told the latter was more prone to cracked screens (their words, not mine). I've purchased the same brand of el cheapo silicone case off eBay for the past couple of phones (no screen protectors, mind you as I don't believe they're needed) and my phone looks pristine. Gorilla Glass is a good thing.
Not sure what my next move will be. My S7 will soon be paid off... however, I'd like to move back to Verizon as their coverage is better in my nape of the woods. Unfortunately, I've had too many dropped calls on AT&T and won't be sticking around for more. The S9+ would get my money today if I had to make a move... 6 gigs of RAM? Yes, please!
YMMV.
