This guide covers everything you need to know about the Touch4Keyboard/Mouse app, a specialized tool for Android users who want to play mobile games using physical peripherals without rooting their devices. What is Touch4Keyboard/Mouse?
Touch4Keyboard/Mouse is a "touch emulation" app developed by P4FW. Unlike standard remote apps that turn your phone into a mouse for your PC, this app does the opposite: it allows you to use a physical keyboard and mouse to control touch-based games on your Android phone or tablet.
Key Advantage: It works without requiring root access, developer options, or complex client/server software on a PC.
Best For: FPS shooters and landscape games (like PUBG Mobile) where precision control is an advantage. Essential Hardware Requirements
To use this software effectively, you need a specific hardware setup to bridge your peripherals with your mobile device:
OTG Cable: To connect USB devices to your phone's charging port.
USB Hub: Ideally with at least 3 ports to accommodate both a mouse and keyboard.
Arduino Board: This is a unique requirement for this specific app. It requires an Arduino Micro, Pro Micro, Leonardo, or Beetle (models based on the Atmega 32u4 controller) to act as the hardware translator. Peripherals: Standard wired keyboard and mouse. Download and Setup Guide
The app is a paid tool typically found on the Google Play Store for approximately $5.99.
Download the App: Purchase and install the official version from the Google Play Store to ensure you receive the latest updates (currently version 3.21). Connect Hardware: Touch 4 Keyboard Mouse Apk Download
Plug the USB Hub into the OTG Cable, then plug the cable into your phone.
Connect your wired mouse, keyboard, and the programmed Arduino board to the USB Hub.
Configure Permissions: Launch the app and grant all requested permissions. Since it doesn't use root, it needs these to simulate touch inputs on top of your games.
Map Controls: Use the app's interface to assign keyboard keys and mouse movements to specific areas on your screen where the game's touch controls are located. Alternative Apps
If you don't have an Arduino board or are looking for different features, consider these popular alternatives:
Bluetooth Keyboard & Mouse: Turns your phone into a remote mouse/keyboard for a PC or TV via Bluetooth.
Octopus - Gamepad Mouse Keyboard Keymapper: A popular free alternative for gaming that supports various peripherals, though compatibility can vary.
Remote Mouse: A highly-rated choice for using your phone as a wireless trackpad and keyboard for your computer.
Touch4Keyboard/Mouse is a specialized Android utility designed to bridge the gap between external peripherals and mobile games that were built strictly for touchscreen input. Unlike standard "remote mouse" apps that turn your phone into a PC controller, this app allows you to use a physical keyboard and mouse to play Android games without requiring root access or developer options. Key Features This guide covers everything you need to know
Hardware Integration: Requires an Arduino board (models like Micro, Pro Micro, or Leonardo) and a USB hub/OTG cable to function as a physical hardware bridge.
No Software Hacks: Operates without server/client software, root permissions, or typical developer hacks that might trigger anti-cheat systems.
Landscape Support: Specifically optimized for landscape-oriented games, allowing users to map keys to specific touch coordinates.
Precision Control: Updates often include fixes for high-end "Pro Gamer" mouse movement events to ensure high responsiveness. Download and Installation
The official version was historically available on the Google Play Store for approximately $5.99. For those looking for APK files or community-supported versions:
Direct Download: Reliable APK listings can often be found on platforms like AppBrain or community forums like 4PDA. Installation Requirements: An Android device running OS 5.1 or higher. An OTG Cable and a USB hub (at least 3 ports).
An Arduino Leonardo or compatible board (Atmega 32u4 based) to act as the mapper. Alternative Options
If the hardware-heavy setup of Touch4Keyboard/Mouse is not what you need, consider these alternatives:
For PC Remote Control: Use Remote Mouse or Bluetooth Keyboard & Mouse to turn your phone into a touchpad for your computer. Pro Tips for Optimal Performance:
For Gaming Without Hardware: Apps like Octopus allow for keymapping but may require specific permissions or encounter anti-cheat issues.
Open Source Alternatives: Projects like KeySync use Shizuku for permission handling to map mouse and keyboard events to touch without root.

The app is available on the Google Play Store, but many users search for the Touch 4 Keyboard Mouse APK download to get the latest version faster or to install it on devices without Google services (like some Amazon Fire TV sticks or Chinese ROM phones).
