I gotta say this is the best beta I have tried out of all. The phone works wonders as if it was an official release. I love the Night Mode on it, as I love black stock colors rather than 3rd party themes which will start going on 14 day trial from now on and pushing sales as well. Phone's performance is amazing. Battery life is even better. Media volume is higher and with more bass. Wow, I'm pretty impressed with Samsung
