The new version includes Full HD video recording, a local calendar, and much more.

NTC IT "ROSA" company introduced a new version of the mobile operating system "ROSA Mobile" 3.1. The update affected the camera, messenger, calendar, mail, connection to networks and computers, as well as interface settings.

The new version features Full HD video recording – 1440 x 1920 pixels for vertical shooting and 1920 x 1440 for horizontal. Changes also affected working with long videos.

"ROSA Messenger" now implements push notifications via the OMMG Technology service, so messages are displayed even when the application is closed. Photos in chats are now loaded as previews, and originals can be obtained separately. Group chat filtering and additional contact management features have also been added.

Another new feature is the local "ROSA Calendar". It allows creating, searching, and deleting events, setting reminders, and saves data after device reboot. Connection to third-party calendar services is not required for the application to work.

For Wi-Fi, you can now create a QR code with the parameters of the current network and transfer it to another device. USB connection options to a computer have also been expanded: file transfer, modem mode, and charging are supported.

The developers also added three system font sizes, optimized "Gallery" for large collections of images, and expanded the management of active sessions and connected devices in "ROSA ID".
