The Samsung Galaxy S9 and S9+ have been out for a little over a month now. Samsung and the carriers have not released an update for their phones since the day one update. Almost every Snapdragon Galaxy S9 and S9+ are still running the February security patch from launch.

The updates in this guide are for the Snapdragon variants of the Galaxy S9 and S9+. The Exynos variants of the phone have already received the March security update, but nothing past that. The update has not been certified in the Play Store and doesn’t pass SafteyNet, but while running this update on my own device, Google Pay and all the Google apps are still working. This build includes the May security patch and bug fixes, though we do not know any specific bugs that were fixed. This update also adds Chatbots for AT&T users.
