Android definitely has a lot more users all over the world, as you can view here. I've seen it on the Android forums and elsewhere that it has been said that Android is the best app I've ever used in my life. Although there are many iOS fans, there is no doubt about that either.
Modern mobile operating systems for Android have so many modifications that you can get lost among the descriptions. The easiest way is to follow the news regularly. I do this when I read blogs on avanda.id. They explain complex things in simple language and this is what I need. Do you read gadgets reviews?
