Logitech MX Master 4: Fix Unresponsive or Double-Clicking Buttons

Cleaning Physical Debris

• 💡 Clean around the buttons using a small soft brush or compressed air to remove trapped dirt and debris.
• ⚠️ Avoid using sharp or metallic tools, or anything that could break inside the mouse and worsen the problem.
• 🎯 Hold the mouse at an angle and use short bursts of compressed air around each button for a thorough cleaning without disassembly.

Software and Firmware Updates

• ⚙️ If cleaning doesn't resolve the issue, it might be a software problem.
• 💻 Open the Logi Options Plus application on your computer.
• 🖱️ Select your mouse within the application, navigate to settings, and click 'Check for Updates'.
• 🚀 Download and install any available updates for your mouse's firmware and software to potentially fix button issues.
