android phones shown here have a very poor history of having latest OS many models including the most expensive in history are released with old software and sometimes lag multi generations behind, consumers have resorted to sharing the ROM's between each other doing custom versions to update their own phones instead of doing what the phone vendors want them to do which is buy a new phone to get the latest software, torrent is one of the distribution methods of the software. As it stands the majority of it is legal practice.
