    This is so wrong, there’s 2018 and author tries to make differences between AOSP and Google apps using screenshots from Android 4.x.x (released in 2013) as well as not taking LineageOS and other forks into account, which are greatly improved in these fields. Same for statistics and graphs, these are limited to 2013 only.

    For me, it clearly looks like some old repost with minor updates.
