Before Android 4.4 all devices run Android WebKit as their WebView. (Is this the same Android WebKit as their default browser? Don\u2019t know yet.)
\nFrom Android 4.4 the WebView is Chromium 30.
\nFrom Android 4.4.3 the WebView is Chromium 33.
\nFrom Android 5 the WebView is Chromium 37. In addition, the promise is that the Android 5 WebView will be updated to newer versions app-wise, i.e. without a firmware update. I will keep an eye on that.<\/p>\n

Before Android 4.4 all devices run Android WebKit as their WebView. (Is this the same Android WebKit as their default browser? Don\u2019t know yet.)
\nFrom Android 4.4 the WebView is Chromium 30.
\nFrom Android 4.4.3 the WebView is Chromium 33.
\nFrom Android 5 the WebView is Chromium 37. In addition, the promise is that the Android 5 WebView will be updated to newer versions app-wise, i.e. without a firmware update. I will keep an eye on that.<\/p>\n
