Solution 1Recommended

Use the Samsung Device Screen as a Touchpad

Since the issue primarily affects mouse input in DeX mode, using the phone's built-in screen as a touchpad bypasses the limitation.

Microsoft Word for Android is heavily optimized for touch interactions. When connected to DeX, the app sometimes fails to register click-and-drag mouse events. Utilizing your smartphone's screen as a trackpad allows you to use touch gestures to manipulate objects.

1
Launch Samsung DeX

Connect your Samsung Galaxy phone to your external monitor and launch the DeX desktop environment.

2
Enable Touchpad Mode

Swipe down the notification shade on your phone's screen and tap the 'Use your phone as a touchpad' notification.

3
Select and Resize Objects

Open your Word document on the DeX screen. Use your phone's touch screen to tap, hold, and drag the corners of pictures or tables to successfully move and resize them.

Frequently Asked Questions

Why can I resize pictures with my finger but not my mouse in Word for DeX?

Microsoft Word for Android is primarily optimized for touch interfaces. Its support for external mouse events, specifically click-and-drag actions required for resizing objects, is currently limited or bugged in desktop-emulation environments like Samsung DeX.

Will reinstalling Microsoft Word fix the DeX resizing issue?

No, reinstalling the Word application typically does not resolve this issue. The problem stems from how the Android version of the app handles mouse input protocols, rather than a corrupted installation file.

Does this mouse issue affect other Microsoft Office apps on Samsung DeX?

Yes, many users report similar external mouse input limitations when trying to select, move, or resize objects, shapes, and charts in Microsoft Excel and PowerPoint for Android while using DeX.

Is there a permanent fix for mouse support in Word on Android?

A permanent fix requires Microsoft to release an update for the Word for Android app that fully supports advanced external mouse events. Users are encouraged to submit feedback directly through the Help & Feedback section in the Word app.
