Am I right to say that? because I claim that there are only two phone operating systems in the world! 1. Android — the Google operating system that it is used in the brands: Samsung, Huawei, Nokia, Motorola… 2. iOS — used in all cell phones manufactured by Apple. Previously there was a lot of competition, from cell phone operating systems, for example,
blackberry system, java, ios, android, windowns phone.
Am I wrong to say that? I don’t think so, because there are only two mobile operating systems that currently dominate the world, so I can say that there are only two phones in the world.
