Samsung has started rolling out a new update to its Galaxy Note5 smartphone from last year. The update, among other changes, brings the Grace user interface, which made its debut on the ill-fated Galaxy Note7, and will probably also arrive on the S7 series with the Nougat update .
Currently, only South Korean Galaxy Note5 units that are on the Korea Telecom's network are getting the update, which arrives as firmware version KKU2CPI1, and is based on Android Marshmallow version 6.0.1.
As is usually the case with OTA rollouts, it may take time for the update to hit your device. Meanwhile, if you feel impatient, you can manually check for the update by heading to your handset's Settings menu.
