Google yesterday released the Chrome 25 beta for Android 4.x for smartphones and tablets, a version number in sync with the release for personal computers. Previously, the only option was the stable version of Chrome for Android, which is still way back at version 18.
The Chrome for Android beta is available on the Google Play app store, but only by following that link — it’s not visible in Google Play’s search, Google said. The beta version can be installed and run side by side with the stable version.
