Edith is an Oracle smartphone. While Her phone is definitely smart, it doesn’t appear to be any obvious brand.
They’re both touchscreen, but Edith has a basic physical Home button that doubles as a control for the music player. Edith is designed to be extremely intuitive, easy for anyone to just pick up and use. I’d imagine that the touch keyboard for texting is AS HUGE AS POSSIBLE given the screen dimensions.
The interface of Her phone is a little more complicated, although just as intuitive if you have the right kind of mind. It involves rapid touch manipulation of the little red boxes (folders) to navigate through the terrifying amount of information stored on it.
That one tiny yellow box up top is probably a Home button, although I would personally be a little scared of poking it to find out.
