I have an unlocked N10+ on Verizon. In the Samsung Members app I saw the banner at the top of the page (banner 1/12) and scrolled to 2/12 and selected it to enter the Beta Program. I'm DL the update now.

Although I like using Night Mode, I would rather have a white Google search bar (it defaults to black) . I can't find a way to change it. I have gone to the app settings and tried to customize it with no luck.
