About Microsoft Edge Beta
Microsoft Edge Beta is a pre-release build of Microsoft Corporation's browser, distributed under the package name com.microsoft.emmx.beta. It lets curious users work with upcoming functionality ahead of the general rollout while still delivering a complete everyday browsing and communication experience.
Beta Channel Purpose
Microsoft Corporation uses this channel to publish a stabilized preview of its browser so that feedback and real-world use can shape what eventually lands in the mainline release. Because it is a beta, it sits between a rough test build and the final product, balancing new ideas against the reliability most people expect from a daily driver.
Version and Release Details
The latest available build is 155.0.4283.25, issued on 2026-09-30. Anyone tracking the app over time can use that version string to confirm whether an installed copy matches the current offering on this listing, or to note which build they were running before an update is applied.
Device and Storage Needs
The build requires Android 10.0 or newer. Installation package size is 246.2 MB, so devices should have comfortably more free space than that available before the setup process begins, accounting for the initial unpack plus any cached data generated during first use.
Where It Sits in Its Category
The app is filed under communication, reflecting the way a modern browser serves as a hub for messaging, accounts, shared links, and online collaboration rather than as a passive document viewer. As such it is aimed at people who treat their phone as a connected workspace.
