This is a wonderful phone. It runs so smooth and functions well. I love the amount of customization available on it. The camera is amazing and the amount of modes are great. the video quality on this is great too. It's very comfortable in the hands too. Overall, for what you pay for, awesome working phone. The battery, I wish lasted a bit long than it does, but it's not to much of a problem.
I have loved my S2 and S4, but as always with new releases, some features are missing. The Swipe keyboard is missing. On previous Galaxy phones you had a Samsung Keyboard and a Swipe Keyboard, they are both the same on the S6, which I find makes more mistakes and I'm continuously having to fix what I Swipe. I hope they fix this in the first update. Custom ringtone for voice mail is gone, which is a bummer, because I had a fun ringtone to alert me when I missed a call. I also hope they bring that back. The way you close apps has changed, which took awhile to get used to. I found the "thumbprint" lock annoying, especially since the home key is used for so much else and if you held your finger too long, it popped up other boxes when unlocking. It would recognize my finger 1 out of 5 tries and never if your finger was damp or your used the tip or side. I love the new feature where you can set "safe spots" so you don't have to put in your password in your own home, etc. Genius idea! The look is great, but not having a removable back or SD card kind of bites. Switching all my music, pictures, contacts, etc. was a breeze with the Samsung app, although I had a lot of stuff and it took quite awhile, about 2 hours. Everything was transferred perfectly! I'm happy with my new S6, but I hope they fix a few things. The best part, the camera of course. The pictures are stunning! I still prefer my regular camera, but the picture quality really is amazing! The heart/stress monitor is a neat feature too and I'm enjoying the S Health keeping track of my steps. I should mention the speakers are great, sound is great, and having the mouthpiece at the bottom instead of on the back is perfection. Now everyone says, I can hear you so much better! Loving my phone! Wish the USA had gotten all the colors, I really wanted the blue!
