There is Palm. It looks a bit like the first iPhone, but the size of a credit card. https://palm.com/pages/product https://palm.com/pages/product Regretfully, it filled with a lot of carrier spyware (originally Verizon) that eats the battery in the background. If cleaned up, the battery life gets much better (up to two days). But, after a month or so, for me the phone for some reason factory-reset itself. Not sure, if it was an update or initiated by the carrier or a hardware glitch or something else. Nice, clean looking, unlocked, very inexpensive hardware (<$100 refurbished), but very poor android build.
