The Fragmentation Trap: Why Android 16 is Struggling to Overtake Its Own Ancestors

Google’s updated Android distribution metrics show Android 16 at 7.5% adoption as of December 1, 2025, with Android 15 leading at 19.3%, followed by Android 14 at 17.2% and Android 13 at 13.9%, underscoring ongoing fragmentation compared to iOS. The report attributes slow updates to OEM customization and carrier validation cycles despite Google’s earlier Android 16 release, while noting that Project Mainline and Google Play updates increasingly deliver features and security fixes independent of full OS upgrades.
