After the launch of Android 13, all the companies started distributing their own OS based on Android 13. Samsung has so far provided the One UI 5.0 update based on Android 13 to more than 60 devices, while OnePlus has provided more than 15 devices. There are many other companies like Realme, Xiaomi, Sony, Nokia, Asus, etc who have released Android 13 updates for their devices.
Android 13 is now on 5.2% of all (GMS) Android devices, according to the latest version statistics provided by Google in Android Studio! 18.9% are on Android 12. Android 12L isn’t distinguished here, but likely a negligible % are running it.
Meanwhile, 24.4% of Android devices are on Android 11 and 19.5% are on Android 10. That means ~32% of Android users are on versions that no longer get security backports. February 2023 is the last Android Security Bulletin that’ll include Android 10 security backports, so that % will grow soon.
