The phone has a great camera (including front facing) it's extremely fast. The finger print scan, spo2, heart rate monitor in the s health app is super neat and a great addition to tracking health. I got the 64 gb which is a large amt of space however the only thing I would change on the phone is Including the SD card slot.
I've had a Galaxy S3 for the past four year and really liked it. But the S6 is a definite upgrade. And I was able to get the 64 GB phone for the same price as the 32 GB. The camera is great and the extra storage will allow me to keep more pictures on my phone.
I'm only a couple of weeks in, therefore any review I give is going to be relative. With that stated the camera is amazing, the apps and on board software seem to work effortlessly without bogging down the phone, and it is fairly easy to get up to speed when using. Overall I expect to get great use out of my phone.
Pros: Realistic color, Bright display, Durable
Cons: speakers are not as great as my previous droid
