Owners of Samsung's Galaxy S22 series, Galaxy Z Fold 4/Flip 4, and A53/A33 will not receive the upcoming One UI 8.5 update. This decision stems from the update being built on a significantly different Android base, Android 16 QPR2, rather than the original Android 16.

• Samsung is reportedly halting development for older devices, including the Galaxy S22, on the One UI 8.5 update due to its complexity.
• The One UI 8.5 update is based on Android 16 QPR2, a newer branch with substantial platform changes, making it difficult to port to older hardware.
• While major OS upgrades are complete for these devices (they received Android 16), they will continue to receive vital security patches.
