When it comes to software updates, Samsung is really on the money nowadays compared to a few years ago. The Galaxy A30, for example, was supposed to get Android 10 next month, but Indian users are already receiving the new software which comes with One UI 2 on top and the February 2020-dated security patch.
Since we are talking about an update from Android Pie to Android 10, it is not surprising that the software update weighs no less than 1.4 GB. The version number of the new firmware is A305FDDU4BTB3 and its rather long list of features includes a Dark mode that also darkens the wallpaper, new navigation gestures, improved facial recognition, enhanced Digital Wellbeing capabilities, and more.
Unfortunately — at least according to SamMobile, since we were not able to test the new firmware on a Galaxy A30 ourselves — the update lacks the built-in screen recorder.
As usual, the update can be downloaded over the air (go to Settings > Software update > Download and install) or by downloading and flashing the firmware image with the help of a Windows PC.
