Someone clearly had a lot of fun making all of those components. Adorable and whimsy. One nitpick - when writing uppercase letters in text field they should make larger ripples than lowercase.
Another nitpick: why are only the button outlines having a jelly effect and not the texts written on them? This makes them feel physically unconnected.
There is a severe lack of compact smartphones in the market. Are there any devices available with regular OS updates, that fit into normal sized pocket?
I have found a very usable phone (for what I do, which is not much) in low cost Chinese "mini rugged phones" namely I had (until I broke the screen and battery was not in very good condition) a "king kong mini" and then I got the (slightly larger) "king kong mini 3" (the 4 is the latest model, I believe). They are slightly heavier than you would expect, but have very long autonomy and fit nicely in a shirt's pocket.
This is actually a really great feature for everyone else trying to reduce their phone use without switching to different "dumbphone". But why mandatory lock by passcode? I agree, that adding more friction would prevent user to switch back to standard UI, but still - it should be optional.
