Google Chrome is not the default browser on Android 4.3+. There are now at least eight Chromium-based Android default browsers, and they are all subtly, though not wildly, different.
The number of Chromium family members has recently risen from nine to eleven with the addition of HTC and LG Chromium, default browsers for modern HTC and LG high-end devices.
I don’t see the problem. The engine is the same and that is the biggest part, if they each have their own interface that might make at least one of them halfway decent..
