Samsung Galaxy S9 and S9+ update adds Night Mode function, other improvements
Apart from the Night Mode functionality, the update contains a bucketload of improvements meant to further enhance performance and stability. For example, the performance of the camera has been improved, and the same goes for the security of the phone and the usability of QR Code reader.
Other improvements included in the update hit areas like Messaging, Contacts, and Gallery. The update is quite sizeable at 575MB, so make sure you have enough free space on your phone. Keep in mind that once you apply the update, you won't be able to downgrade to the previous version of the OS.
Now, it appears that the new update is rolling out in Asia first, TizenHelp reports. For the time being, Samsung Galaxy S9 and S9+ users in Thailand, Vietnam and the Philippines should be able to download the June update, but we can safely assume a wider rollout will commence in the next few days.
