Adult entertainment site Pornhub has released data on how people access its portal from various Android operating systems - something that Google never reveals about.

In 2019, 48 per cent of its Android traffic on its website came from Pie (last yeara¿s major update from Google), 23 per cent from Oreo (2017's update), and 12 per cent from Nougat (2016's update).

The newly-released Android 10 (Q) represented 2 per cent of the year's traffic on Pornhub, reports The Verge.

By comparison to Pornhub's statistics for 2018, Android Pie has seen significantly higher adoption than Android Oreo did.

Another noticeable statistic is that Android usage has decreased while iOS has increased, making iOS the most used mobile operating system for browsing Pornhub. The latest iOS 13 version is used 71 per cent times.

Overall, the adult streaming service revealed that iOS accounted for 52.8 per cent of all mobile traffic in 2019 while Android accounted for 46.6 per cent of traffic this year.

"The data is interesting because Google hasn't updated its own dashboard of how many devices are on each version of Android since May. So for months, there haven't been any public figures about the current state of Android OS adoption," the report said on Wednesday.

The data was released as part of Porbhub's annual 'year in review' listing.

Pornhub's data only measures how much traffic it got from each version of Android.

Google's Android distribution dashboard, however, tracks how many devices are running each version of Android.
