Which Android versions should I test on?

Android statistics chart

It has been an interesting couple of months for Android enthusiasts. The highlight probably has been the release of the Samsung Galaxy S8 and S8 Plus. Next to releases of new devices, Android Nougat is being released by manufacturers to more devices. We can see this in the Android statistics for the last three months. Android Nougat has gained a market share of 7.1% compared to the 1.2% it had in February. Together with the growth of Nougat, we can see the stabilization of Android Marshmallow and Lollipop. Kitkat still holds a marketshare of 18.8%, losing only 3.1% over the last three months.

Looking at specific version numbers we can see the same trend. Android 7.0.x and 7.1.x are gaining marketshare while Android 5.0.x, 5.1.x and 6.0.x are stabilizing. All older versions are slowly but steadily losing marketshare.

Based on these statistics, we can conclude that Android Nougat is really taking of now. For testing, it should be one of your priorities. Based on the trends we have seen in the past, Android Nougat will quickly gain more marketshare in the coming months. We expect it to be the largest Android version in about a year.
