Just wondering what does samsung have to do with android?))) Many offices in 2018 will die due to the fact that they forgot that Android belongs to google and therefore the United States. Just as many people still think that qualcom's snapdragon is a Chinese processor. Well, let's compare a helicopter with a quadcopter!
Yes, but we won't buy cars of the old model year, because they came out earlier? Cars are improving every year, the same with smartphones, that is, it is better to wait a year than to regret it later. Of course, you can buy earlier, but every year it gets better and better. Moreover, the main competitor of Apple is Samsung, Samsung pulled out a lot earlier than Apple. Android will always be better than Apple.
You can google the answer to this question. Here's what Wikipedia tells us: the first release of Android on September 23, 2008, and iOS (iPhone OS) on June 29, 2007. It turns out that iOS appeared earlier. Such is the case.
