It's very smooth and quick Steven. It's large with it's 5.0 screen and the boom speakers on front. You will like sense 6.0, it's very well integrated and quick. If you are into social, it has a nice blinkfeed page that isn't annoying but quite functional. I put a case on this phone... first phone ever. The case is beautiful but with it's rounded edges and back I was a bit concerned about the grip. I have no complaints about the camera. I'm not a photo buff and those that are seem to think it's short sheeted in comparison to S5. The pics I've taken are as good or better than what I'm accustomed to. The battery life is simply incredible. A normal 16 hour day will not take half of the battery life. A day of little use will leave you with 85% . All in all it's a great phone. No glaring negatives for me to report.
