I like the skin, it's light and doesn't totally bog down the phone like others do. I love the launcher (I almost always download nova prime, haven't even downloaded it to this phone), I really really like the file browser. It's similar to the one Asus has on the play store, but polished a bit better, unlike other skins I feel this phones power saving mode actually makes a difference without destroying performance, the camera app is WAY better than the one from stock Android. I also like the short notification pull down menu. I can access Wi-Fi, data for both Sims, sound and gps. (They can be changed) , AND the voice recorder works extremely well. You can record in mid quality mp3 or high quality WAV. AND you can TRIM after..
The most important things when I'm setting out driving. It's similar to that seem in nougat.
it's missing some simple things like on screen button options, a dark settings option, and it seems like there will be more themes made available than miflavor and stock Android. but coming from touchwiz, I can say I'm very pleased.
One bug I've noticed is while I'm on phone calls, her notification panel goes to garbage. It gets EXTREMELY laggy.. I mean... HORRIBLY laggy. Every other aspect of the phone works no differently than when I'm not on call.
