Android os Marshmallow is seeding for the Exynos-powered version of the particular Samsung Galaxy Note 4, with reports of the OTA arrival to arrive from various parts with the world. So far, we now have gotten tips from Poland, India and the US ALL, and the screenshots below result from Turkey (though the device is running over a Polish ROM).
From that which you gather, the firmware is at the whereabouts of 1. 3GB (a small bit less than the Sprint Marshmallow build for your Note 4) and delivers the OS version to be able to 6. 0. 1. The users inside the Turkish forum (source link below) report the Screen off memo feature from your Note5 has been carried up to the Note 4 at the same time. And as you is able to see, the icons have gotten the identical design as the ones around the latest Note.
We do have a note 4 N910C on the job, but it is nonetheless on its trusty Lollipop 5. 1. 1, so we can't report first hand around the changes it brings. With any luck ,, that'll change sometime shortly.
