I did get to take two pictures, looks like the UI is very adaptive to this resolution. Also personally i think it looks lovely. pic.twitter.com/tqhZ51p5xj— Gustave Monce (@gus33000) January 20, 2021
Gustave is quite clearly the man in terms of this sort of hacking, so make sure you follow him on Twitter if you want to keep track of progress.
But - as I say - this will never be a useable day to day smartphone. The complexities in creating such a thing are enormous, and it only takes a single aspect that's broken (SIM, camera, speaker, etc.) and the whole pack of cards comes tumbling down in terms of usability. Plus the UI has compromises on a much smaller screen that it was designed for, of course.
Still, all power to Gustave and his programming prowess!
