I don't get it. Comparing the Sony Z3 to the Samsung S6, I can't fathom why I'm loving the Z3 so much more! I think this is the 2nd android device I really like, the first of which is the Xperia ray. Never really got into the Nexus 4, and the android tablets I have/had? Blargh. No thanks. IOS ftw there.
To me, Z3 vs S6:
The ergonomics on the Z3 are poorer.
The hardware feels cheaper.
The screen just does not compare at all.
The camera is pretty crap compared to the S6.
The charger that came with the phone evidently doesn't supply enough current to charge the phone (I have to use my Nexus 4's charger lol)
Opening the waterproof flaps to charge the phone is fiddly.
Instructions on how to insert the sim card are practically non-existent.
The torchlight is an epic fail.
But somehow, the UI and feel of the phone is just right. I really like the included widgets, they just align on the home screen just right. THE BACKGROUND SCROLLS! And best of all, I didn't have to waste time "rooting" the phone or going through the app store to find replacements. It just frakkin' works!
So glad the S6 is sold. Hope the new owner likes it :)
