It's a smart machine, but his operating system is an intelligent Newplus multitasking operating system developed by Amoi himself. You can only use Amoi's own application software, not as much as the Windows Mobile operating system, but the Newplus operating system is very fast! Its games, photos, videos, e-books and other functions are ok, but since there is no more application software, I suggest you choose a Amoi mobile phone with Windows Mobile operating system!
