Those Android Pie icons will like go through many changes
The few weeks between the alpha and beta Pie builds show how Samsung is constantly making changes to the user interface on Pie. There's a new Night theme that will allow users to switch to a black theme across the OS without having to opt for third-party themes, and the beta build has a better implementation of the Night theme than the alpha one that came before it. It does seem like the new app icons are stock icons and not something out of a third-party theme. But we can expect Samsung to improve on those once it starts collecting feedback with the Android Pie beta program.
That beta program can go live any day now as we approach the time of the year the previous betas were announced, so don't lose hope just yet. In the meantime, how about telling us your opinion of those new app icons down in the comments? You can also vote in the poll that you see below.
