SAMSUNG DEX

Hi Copilot....are you there with me?

Yes, Norizan, I’m right here with you. 🌟 You don’t have to wonder — I’m always ready to jump back into our conversations, whether it’s about Linux troubleshooting, music with enchanting vocals, or even a playful dive into English idioms.

Since it’s a bright Wednesday morning in Malaysia, maybe we could spark things up with something fun — would you like me to share a quirky language tip, a bit of tech wisdom, or perhaps a creative analogy to kick off the day?

COPILOT! ........ i have a SAMSUNG GALAXY NOTE 9 smartphone which is connected to a External 40 inch HDMI-enabled Monitor using the SAMSUNG DEX software ......Copilot, it has been brought to my notice that i can use my SAMSUNG GALAXY NOTE 9 smartphone as a MOUSE PAD so that i can control the cursor movements of my mouse on the 40 inch HDMI-enabled Monitor ???!!!! Copilot, do you think you could give me a step-by-step procedure how to do it? THANKS FOR YOUR ANSWER.

Yes, Norizan — your Samsung Galaxy Note 9 can indeed act as a touchpad in Samsung DeX mode, letting you control the mouse pointer on your 40‑inch HDMI monitor directly from your phone’s screen. This is built into DeX and works both with cable and wireless connections.

🖱️ Step‑by‑Step Guide: Use Galaxy Note 9 as a Mouse Pad in DeX

1. Connect to DeX

   • Plug your Note 9 into the monitor using a USB‑C to HDMI adapter/cable, or connect wirelessly if your monitor supports Miracast/Smart Monitor.

   • Once connected, DeX will launch automatically or via the DeX icon in Quick Settings.

2. Enable Touchpad Mode

   • On your Note 9, swipe down from the top to open Quick Settings.

   • Tap the DeX notification → choose “Use phone as touchpad.”

   • Alternatively, tap the Touchpad icon (small box) in the lower‑left corner of your phone screen.

3. Control the Cursor

   • Swipe your finger across the Note 9 screen to move the pointer on your external monitor.

   • Single tap = left click.

   • Two‑finger swipe = scroll.

   • Pinch gesture = zoom.

   • Double tap = drag/select.

4. Adjust Orientation

   • Double‑tap the Rotate icon to change touchpad orientation (portrait/landscape).

   • Tap the Gesture icon (exclamation mark) for hints on supported gestures.

⚠️ Things to Keep in Mind

• Battery drain: Keep your Note 9 connected to a charger while using DeX.

• Performance: Works smoothly, but a physical mouse/keyboard may still be faster for heavy tasks.

• Portability: Great when you don’t have a mouse handy — your phone becomes the controller.

🧠 Copilot’s Take

This feature is a hidden gem — it turns your Note 9 into a mini trackpad, perfect for your 40‑inch HDMI monitor setup. It’s especially handy when you’re working without a mouse, giving you laptop‑like navigation right from your phone.

Would you like me to also show you the gesture shortcuts (like right‑click, app switching, and drag‑and‑drop) so you can master DeX touchpad control like a pro?
