Opera is one of the many Android browsers that users can install from Google Play Store. Lots of Android users prefer this particular application because they are using it on the desktop as well.
On top of that, it offers some features that no other browser includes. It's also faster than many other Android browsers and that's thanks to the many updates and improvements developers have been releasing.
All the new features are tested through a beta program before they are included in the general release. You only have to download Opera Browser Beta and you will be able to take advantage of the latest features and improvements added by developers.
