Can You Run Microsoft 365 Desktop App in DeX Mode on a Samsung Galaxy S7?
Question details
The user wants to know if they can run the full Windows desktop version of Microsoft 365 using Samsung DeX on a Galaxy S7, or if they are limited to the mobile version.

- Product
- Microsoft 365
- Device & OS
- Samsung Galaxy S7 / Android
- Scenario
- Using a Samsung Galaxy S7 in DeX mode connected to a monitor, keyboard, and mouse.
- Observed behavior
- The user needs clarification on whether the full desktop functionality of Microsoft 365 is available or if only the mobile Android app is supported in this environment.
Ensure your Samsung Galaxy S7 is fully updated, and you have a compatible monitor, keyboard, and mouse properly connected to activate the Samsung DeX environment.
Use the Microsoft 365 Mobile App via Google Play
Since the Galaxy S7 cannot run full Windows desktop applications, you must use the Android mobile version of Microsoft 365 optimized for DeX.
A Galaxy S7, even in DeX mode, is an Android device and cannot natively run the full Windows desktop versions of Word, Excel, or PowerPoint. Samsung DeX provides a desktop-like experience, but it still relies on running Android applications.
Available features in DeX mode depend on your specific Android version, the Microsoft 365 app version, and whether you have an active Microsoft 365 subscription. For advanced tasks requiring full desktop functionality, a standard Windows or Mac computer is required.
Open the Google Play Store on your Samsung Galaxy S7, search for 'Microsoft 365', and tap 'Install' to download the official mobile app.
Connect your Galaxy S7 to an external monitor, keyboard, and mouse using a compatible DeX cable or dock to activate the Samsung DeX desktop interface.
Open the Microsoft 365 app from the DeX app drawer and sign in with your Microsoft account credentials to access available mobile editing features on the large screen.

Use WPS Office for a Seamless DeX Desktop Experience
If you are looking for a fully featured, desktop-like office suite to use on your Samsung Galaxy S7 in DeX mode, WPS Office provides an optimized, lightweight, and highly compatible alternative to Microsoft 365 without requiring an expensive premium subscription to edit on external displays.
- 1. Download WPS Office: Open the Google Play Store on your Galaxy S7, search for 'WPS Office', and install the free application.
- 2. Connect to DeX: Plug your phone into your DeX hardware setup (external monitor, keyboard, and mouse).
- 3. Enjoy Desktop Editing: Launch WPS Office from the DeX interface to enjoy a multi-tabbed, desktop-class editing UI completely for free.

Frequently Asked Questions
Do I need a Microsoft 365 subscription to edit files in Samsung DeX?
Yes, typically Microsoft requires an active Microsoft 365 subscription to unlock the ability to create and edit documents on external displays like Samsung DeX, even when you are using the free Android mobile app.
Why do some features from desktop Office not appear in the DeX version?
Samsung DeX runs the Android mobile version of Microsoft 365, which is designed for touchscreens and mobile processors. It does not include the advanced features found in the full Windows or Mac desktop versions, such as complex VBA macros or advanced data modeling tools.
Can I run Windows applications directly on my Galaxy S7?
No, the Galaxy S7 runs on the Android operating system and uses an ARM-based processor. It cannot natively install or run standard Windows executable (.exe) applications.
How can I get a true desktop Office experience on a mobile device?
To get a full desktop experience, you can use remote desktop software to connect to a physical Windows PC, utilize a cloud PC service like Windows 365, or switch to mobile office apps that offer robust desktop-mode optimizations like WPS Office.
