Before Samsung's Unpacked event for Galaxy S10 phones, a Reddit user noted that Galaxy Apps is being renamed Galaxy Store.
In addition to the new name, the One UI aesthetic has been updated. As with other Samsung One UI-ified application headers, the Galaxy Store's header occupies nearly half of the screen. This may seem like a waste of space, but you can access more applications with one hand.
Based on the screen capture, the top navigation menu of Galaxy Apps has been moved down into the Galaxy Store. The Galaxy Store also updates the navigation menu options: Home, Games, My Galaxy and Watch. Previously, the navigation menu included trends, games, exclusives, plans and equipment.
Finally, it seems that Samsung has slightly redesigned the application icon. The aesthetics of the yarn and the vivid colors of the front have been replaced by thicker lines and darker hues. It's a more subtle difference, but one that matches other One UI icons.
As nice as the Galaxy Store may appear, a Reddit user noted that the application update did not conform to the overall system night mode found in One UI. It would be a disappointment if it was true, although it may change with a future update.
The renamed Galaxy Store is being deployed as a mandatory update. Be on the lookout for version 4.5.01.7, which weighs just over 20 MB.
