I have bought my android smartphone in 2012 and use a windows phone in 2014 for while.
Windows phone are not user friendly. The windows operating system is very difficult to use, very difficult to manage own file or matters. If an application come on play store of android today, it will come on windows store after one month or later.
And in other hands, Android operating system is very easy to use. So many applications and features are available at play store which makes it easy to use which makes it world’s top Mobile operating system. All updates are easily available.
I love android over Windows.
