After experimenting with it in the beta channel, then doing a bit of A/B testing, it seems that Google is finally ready to roll out bottom navigation in the YouTube app. The update is a combination of an app update, which happened last week, and a server-side update, which is happening now. Assuming you have the former, the later should be coming to you over the course of the next few hours.
Once you have it, gone will be the top tab navigation for Home, Trending, Subscriptions, Shared and Library. Instead, they are all clearly identified on the bottom of the display in the streaming content app.
The change fits the overall style of navigation that Google has been pushing to many of their apps. It also fits more nicely with the
Material Design look that the company is pushing for all developers to use in their app designs.
Feature wise, you won’t find anything new in the update. This is all about the navigation changes.
If you don’t have the latest version of the YouTube app, the OTA should be to you at some point this week and the new navigation will quickly follow suit.
