Lock screen concepts are cool, but I don’t like other stuff honestly.
The notifications panel scrolls vertically, and adding a vertical scroll container in it smells like bad UX (the box with the earphones details).
Also there’s a horizontal scroll indicator at the bottom of sliders, that’s confusing: the scrollable part includes the sliders? If yes that bad, because there’s a horizontal widget inside an horizontal scroll container; if not that is also bad, because user has no clue on what is the scrollable part.
The dialer looks like a stock dialer with a different font, not very impressed.
The gallery design is ok, but when watching a picture I would like to use all the screen pixels I have.
I hope this feedback will make you improve 😎👍
