I adore the phone ^_^ I mean, I'm not going to get too technical with my description but I'll try to tell you all I know, or at least which features make me love it:
64 GB internal storage
You can put an SD card up to 2 T additional storage
Rear camera is 12 mp with super fast focus
Selfie camera is 8 mp with a wide angle lens and fast focus
There's an always on display (you can deactivate it)
Gorgeous display and design <3
Not sure what you mean exactly with warping? Do you mean the ones where it "beautifies" your face and slims it down or distorts it? If so, it still has that feature, but you can turn it completely off now, which you couldn't do on the S6 for some dumb reason. If that's not what you mean though, feel free to show me the picture and I can let you know if mine does it or not.
I think it's worth it to upgrade if you have the S6 or older models
Let me know if you have any questions about it ^_^ I'll be happy to tell you everything, as long as you're not asking about all the technical numbers and specs because I'm not exactly good with those haha
