Does Chrome use Android's standard Webkit?

Question

Android

I noticed that the useragent shows the same webkit version in the standard browser with Android 5.0.2, in the latest chrome and the latest opera. It turns out that under the hood they are the same, as in iOS? For some reason I thought that Chrome for Android uses its own Blink instead of the system one. And why are the results in html5test different if the engine is the same?

Answer 1

But isn't the standard browser in Android 5 chrome?
