Touch 4 Keyboard Mouse is a server-client application. The Android app (your phone/tablet) acts as the remote controller, while a small server application installed on your Windows PC, Mac, Linux computer, or Android TV handles the connection. Once linked via Wi-Fi, your phone’s screen becomes a multi-touch trackpad, a full QWERTY keyboard, and a media remote.
Unlike Bluetooth keyboards or mice, this solution uses your existing home network. It requires no dongles, no pairing hassles, and no extra hardware. If you own a smartphone and a computer, you have a premium wireless input device for free.
| Issue | Solution | | :--- | :--- | | App cannot find PC | Check firewall settings on your PC. Allow "Touch 4 Server" through Windows Defender Firewall. | | Laggy mouse movement | Switch from Bluetooth to a 5GHz Wi-Fi network for lower latency. | | Keyboard not typing | Make sure the PC server is running. On Mac, grant Accessibility permissions to the app. | | Connection drops | Disable battery optimization for Touch 4 in Android settings. |
Dedicated buttons for volume up/down, play/pause, next/previous track, and home/back buttons are built in. You can also launch specific applications (browser, media player) directly from the remote.
Pair the app with a PC-based emulator (like RetroArch or Cemu). Map the phone’s touch areas to emulate a mouse click for light gun games or point-and-click adventures.
Even reliable apps have hiccups. Here’s how to solve frequent problems with Touch 4 Keyboard Mouse.
Issue 1: Phone cannot find the computer server.
Solution: Check firewall settings on your PC. The server uses UDP port 2794. Add an exception in Windows Defender or third-party antivirus.
Issue 2: Cursor jumps or lags.
Solution: Reduce network congestion. Turn off video streaming on other devices. Switch your router’s channel if you live in a crowded apartment building.
Issue 3: Keyboard doesn’t pop up when tapping a text field on the computer.
Solution: On the phone app, manually tap the keyboard icon. Some apps on the PC side (like games with exclusive input) block this feature.
Issue 4: “Parse Error” when installing the APK.
Solution: You downloaded a corrupted or incomplete file. Delete it, clear your browser cache, and download again from a trusted source.
