Microsoft Edge for Android exits beta, stable version released in the Google Play Store
First off, it can sync your favorite websites across devices, so that you can continue to read them from where you left off no matter what device you have with you. It has a QR code reader, voice search feature, and the so-called Hub View.
On top of that, Microsoft Edge comes with an InPrivate mode that prevents browsing data (history, temporary internet files, and cookies) from being saved on your device when it's enabled.
Of course, Microsoft Edge is available for free and should work on any device running Android 4.4 and up. Try it out and maybe you'll find it more useful than other browsers with pedigree.
