This was initially noticed by the folks at Android Police who have noted that the app dropped its “beta” tag recently, but yet for some reason it is still called “Microsoft Edge Preview” on Google Play. Essentially this is Edge for Android devices, where users who use the browser on their Windows 10 PCs can also sync content across platforms.
“Microsoft Edge, now available on Android, creates one continuous browsing experience for Windows 10 users across their devices. Content and data sync seamlessly in the background, so users can browse across devices, without skipping a beat.” It also lets users pick up where they left off, where according to Microsoft, “Go anywhere and pick up where you left off by seamlessly moving content between your mobile device and PC (requires Windows 10 Fall Creator’s Update).”
The app is free so if you are an Edge user on the PC, or if you just want to find a new alternative mobile browser, it could be worth checking out.
