One UI is a user interface (UI) developed by Samsung Electronics for its Android devices running Android 9 "Pie" and later. Succeeding Samsung Experience and TouchWiz, it is designed to make using larger smartphones easier and be more visually appealing. To provide more clarity, some elements of the UI are tweaked to match colors that are based on the color of the user's phone. It was announced at Samsung Developer Conference in 2018, and was unveiled in Galaxy Unpacked in February 2019 alongside the Galaxy S10 series, Galaxy Buds and the Galaxy Fold.

The Samsung Galaxy Note 10 is a line of Android-based phablets designed, developed, produced, and marketed by Samsung Electronics as part of the Samsung Galaxy Note series. They were unveiled on 7 August 2019, as the successors to the Samsung Galaxy Note 9. Details about the phablets were widely leaked in the months leading up to the phablets' announcement.
