According to this source, as of Jan 23, no. 10 is at 18.01%, which is beat by both 11 (23.15%) and 12 (25.29%). This is why you buy a phone with good support, and update your OS. They can’t support everything forever. Progress happens, security changes, and they can’t always backport the fixes, which also takes their talent away from evolving the OS. statista.com/…/mobile-android-version-share-world…
Personally, I get Pixels and install GrapheneOS. They get 5 years of support.
