I love it! Hate the bumper I bought though, so I'm buying a case...
Lightening speed, very smooth and easy to operate, superb keyboard. Continuity is banging: I was texting my husband on my iPad while my phone was being set up, and as soon as the phone was good to go, I closed the iPad and bam! The conversation was instantly continued on the phone. The camera is a dream. Yes, even "just" the 6. Oh, and the calendar is so user friendly!
So far I have zero complaints about the battery life, I got it fully charged, I've been on it ever since and I still have a good 50% battery left.
Got all my pics, music, videos, wallpapers, ringtones, apps, everything works perfectly with the added oomph of being larger and sleeker.
This is a super phone. But I need to explore it further because I know it's still got plenty under the hood.
