The update also has the February 2019 Android security patch along with some system improvements. When Galaxy S9 and S9+ received the stable Android 9.0 Pie update in January, the Night mode feature was absent in it. So, with this new update the phones will be getting the much-awaited Night mode. The update also brings system improvements like Wi-Fi stability boost, improvements to NFC & email and improved hand gestures. The update is of 361.35MB and has the build number G960FXXU2CSB3 for the Galaxy S9 and G965FXXU2CSB3 for Galaxy S9+. Currently, the update is only available in Germany and in the coming weeks it will be pushed out globally.
A dark theme (Night mode) has many benefits than their lighter themed counterparts, for instance, they put less strain on the users’ eyes so they can sleep better. The Galaxy S9 and Galaxy S9+ feature a Super AMOLED-display so the night mode will also improve their battery life. The users can now either choose from the default night mode which is scheduled to turn on after sunset and turn off after the sunrise automatically. But they can also choose the custom setting where they can turn it on/off when they wish, on keep it turned on, forever. The update also brings improved hand gestures so it can register the gestures more accurately. Post the update, when the user pulls down the notification, they wouldn’t see the blur effect. There is also considerable speed-up in the UI and apps department so that they open and work more smoothly now. The Android security issue is also fixed in the update which could allow someone to remotely execute arbitrary code by sending especially designed PNG file. It was a vulnerability which could have been exploited by someone if the user decided to open a PNG file in his smartphone. But currently, there hasn’t been such news.
