How bad can One UI be?

Really bad for Google!

One UI and TouchWiz, ah, yes, we all know those. Developed by Samsung, it’s included in all Samsung Galaxy devices. Sadly for them, they went farther from the Galaxy to the Black Hole! We all know that Android is open-source, and made for developers to build a UI on top of Android. Google. Was. Furious. That’s why they started their own line of Android devices called Nexus. What went wrong here? Google teamed up with many phone developers, even Samsung! Did Samsung use TouchWiz on the Nexus 10?

Doesn’t seem like it! But Nexus didn’t really take off, which led to the creation of the Google Pixel, the phone Google made all by themselves.

Now, about the Pixel, it’s only developed by Google.
