Galaxy M30 update has been pushed a week early. The update comes with software version M305FDDU1BSEA, includes the May 2019 security patch, and is a 1144 MB download over the air.
The Galaxy M30 is getting a rather bare-bones version of Android Pie and One UI 1.1. One UI 1.1 debuted on the Galaxy S10 with features like Digital Wellbeing and Bixby Routines, and only the former has come to the Galaxy M30 with the Pie update. Other new functionality includes a system-wide Night mode, floating mode for the Samsung Keyboard app, Scene Optimizer for the camera app, and a few others, which you can see in the screenshot below. The update also adds Amazon Prime Video as a preloaded app while removing the LinkedIn and Microsoft Office apps.
