About Microsoft Edge Dev
Microsoft Edge Dev is the development channel of Microsoft's Edge browser for Android, published by Microsoft Corporation under the package name com.microsoft.emmx.dev. It is built for people who want to follow the browser's direction before it settles into its mainstream form. The app is listed in the communication category. What this development build offers As a Dev channel release, this build is aimed at testers and curious users who want to see the browser evolve between major milestones. It carries the familiar Edge experience of opening pages and reaching web destinations, packaged in a build that is expected to move more often than a final, frozen release. Anyone wanting a predictable, unchanging tool may prefer something else. Release details for the current build The current release is version 155.0.4283.25, dated 2026-09-30. That string identifies exactly which build is on offer, which matters when you compare it with another build or describe a problem. The listing does not publish a content rating, so there is no published rating to consult when deciding whether the app suits a shared or family device. Device and storage expectations The build requires Android 10.0 or newer. The package occupies 246.2 MB, so a meaningful amount of free storage should be confirmed before installation begins. Devices running system software older than the required version cannot install it, while newer devices satisfy the requirement. Where it sits in the communication category Grouped under communication, the app is placed alongside tools that move information and connect people. A browser fills that role by reaching web-based mail, chat and social destinations from a single place, so links and conversations can be handled without leaving the app. The classification reflects that everyday connected use rather than one narrow, specialist function.
