The first Samsung Galaxy S9 and S9+ updates bring March security patch15
In some countries, Samsung confirmed it will ship the Galaxy S9 and S9+ one week earlier than the market release, which is set for March 16. If you are one of the lucky persons who got his/her phone before they are supposed to hit the shelves, then you'll also receive an update.
It's the first update that comes to the Galaxy S9 and S9+ and while it doesn't bring any new features, it really is an important one. Samsung has decided to release the March security patch, an update that Google launched earlier this month.
The update is meant to address some of the security concerns that Google found in the last few months, as well as fix some issues from Samsung's part (if any).
According to the changelog, the update file weighs in at 242MB and may include (but is not limited to) device stability improvements, bug fixes, further improvements to performance, as well as new and/or enhanced features.
The Galaxy S9 and S9+ are in the second wave of smartphones to receive the March security update after Galaxy A8 (2018), which got it earlier this week.
