Turn Your Android Phone into a Bluetooth Keyboard and Mouse

10 min read Learn step‑by‑step how to use your Android phone as a Bluetooth keyboard and mouse, enabling you to control a PC or laptop without extra hardware. September 27, 2026 12:00

Before you start

Make sure you have the following ready before you begin:

A phone running Android 9 (Pie) or newer – the Bluetooth HID profile is supported from Android 9 onward.
A computer (Windows 10/11, macOS 10.15+, or Linux) with Bluetooth capability.
Both devices charged to at least 50 % to avoid interruptions during pairing.
A stable Wi‑Fi or mobile data connection only if you need to download the helper app.
Permission to install apps from unknown sources (required for some HID apps).

Warning: Enabling the Bluetooth HID profile gives the phone the ability to send keystrokes to the paired computer. Only pair with devices you trust.

Why use your Android as a Bluetooth keyboard and mouse?

There are several practical reasons to repurpose an Android phone for input:

Travel light: When you’re on the go, a single device can replace a spare keyboard and mouse.
Quick presentations: Use your phone as a remote clicker and slide‑advancer without extra hardware.
Ergonomic flexibility: Position the phone on a stand for a mini‑trackpad while you work on a laptop screen.
Privacy: You control the software stack, unlike generic Bluetooth dongles that may have hidden firmware.

Method 1: Using a dedicated Bluetooth HID app (recommended)

Several apps turn Android into a Bluetooth Human Interface Device (HID). The steps below use the popular Bluetooth Keyboard & Mouse app, which is free on the Play Store and works on most devices.

Step 1 – Install the Bluetooth HID app

Open the Google Play Store on your phone.
Search for Bluetooth Keyboard & Mouse (by AppGround).
Tap Install and wait for the download to finish.

After installation, the app will request several permissions: Bluetooth, location (required for Bluetooth scanning on Android 10+), and the ability to run in the background. Grant all of them.

Step 2 – Enable Bluetooth HID mode on the app

Launch the Bluetooth Keyboard & Mouse app.
On the main screen, toggle the switch labeled Bluetooth HID to On. The app will display a small notification indicating it is acting as a HID device.
Tap Settings (gear icon) → Keyboard Layout and choose the layout that matches your computer’s language (e.g., US‑QWERTY).

This step configures how keystrokes are translated. If you use a non‑English layout, select the appropriate option to avoid mismatched characters.

Step 3 – Pair the phone with your computer

On your computer, open the Bluetooth settings:
- Windows 10/11: Settings > Devices > Bluetooth & other devices
- macOS: System Settings > Bluetooth
- Linux (GNOME): Settings > Bluetooth
Make sure Bluetooth is turned on and click Add device (Windows) or wait for the list to populate (macOS/Linux).
In the list of discoverable devices, you should see an entry named something like BT Keyboard or the name you set in the app’s settings. Select it.
When prompted for a pairing code, the app will automatically generate a 6‑digit PIN on the phone screen. Enter that PIN on the computer and confirm.

After a successful handshake, the computer will treat the phone as a standard Bluetooth keyboard and mouse. You can test it by moving the finger on the phone’s screen – the cursor on the computer should move accordingly.

Step 4 – Fine‑tune mouse and keyboard behavior

Return to the app’s Settings screen.
Adjust Mouse Sensitivity to a comfortable level – low values give precise control, high values are faster.
Toggle Tap to Click if you prefer tapping the screen rather than a dedicated button.
Enable Multi‑Touch Gestures (if supported) to simulate scroll wheels or right‑clicks.

These options let you tailor the experience to the way you normally use a laptop trackpad.

Method 2: Using a PC‑side companion app (alternative)

If you prefer not to install an app that runs as a Bluetooth HID on the phone, you can use a companion solution where the phone streams input over Wi‑Fi or USB while a small server runs on the computer. One well‑known example is DeskDock (free version) which creates a virtual Bluetooth mouse using the phone’s touch screen.

Step 1 – Install DeskDock on the computer

Download the DeskDock server from https://deskcop.com (choose the Windows, macOS, or Linux package).
Run the installer and follow the on‑screen prompts. The server runs in the background and creates a virtual input device.

Step 2 – Install DeskDock on the Android phone

Open the Play Store, search for DeskDock, and install it.
Open the app and enable the Accessibility Service when prompted – this permission allows the app to read touch events.
In the app’s main screen, tap Connect. The app will look for the server on the local network.

Step 3 – Connect the devices

Make sure both phone and computer are on the same Wi‑Fi network.
When the server appears in the list, tap it to connect. If a firewall blocks the connection, open port 1730 (TCP) on the computer.
Once connected, moving your finger on the phone will move the cursor on the computer. A single tap acts as a left‑click.

This method does not use Bluetooth, so it works even on devices without BLE HID support. However, it requires a local network and the extra server component.

Testing the setup

After completing either method, verify that the input works reliably:

Open a text editor on the computer and type using the phone’s on‑screen keyboard. The characters should appear instantly.
Move the cursor across the screen; check for lag or jitter.
Try right‑click (if supported) by using a two‑finger tap or the app’s dedicated button.

If everything feels smooth, you’re ready to use the phone as a permanent secondary input device.

Troubleshooting common issues

Device not discoverable: Ensure Bluetooth is enabled on both devices. On Android, pull down the quick settings panel and tap the Bluetooth icon to confirm it shows as “On”.
Pairing fails with “Authentication failed”: Cancel the pairing, restart the Bluetooth service on the computer (toggle off/on), and try again. Make sure you enter the exact PIN displayed on the phone.
Input lag or jitter: Reduce the mouse sensitivity in the app’s settings, and move the phone’s hand slowly while testing. Wireless interference can also cause lag – keep the phone within 3 meters of the computer and avoid other active Bluetooth devices.
Keyboard layout mismatch: Change the layout in the app’s Keyboard Layout menu to match your computer’s language. On Windows, you can also add the same layout under Settings > Time & language > Language & region.
App crashes after Android update: Re‑install the Bluetooth HID app and grant permissions again. Some updates reset the “Allow background activity” flag, which must be re‑enabled.

Safety and privacy considerations

Because the phone becomes a HID device, any malicious app that gains access to the Bluetooth HID service could potentially send keystrokes to your computer. Follow these best practices:

Only install the HID app from a reputable source (Google Play Store) and keep it updated.
Disable the Bluetooth HID switch when you’re done using the phone as an input device.
Regularly review the list of paired Bluetooth devices on your computer and remove any you no longer use.
If you work with sensitive data, consider using a dedicated “work” profile on Android (Settings > Accounts > Work profile) and install the HID app only there.

With these steps completed, your Android phone is now a fully functional Bluetooth keyboard and mouse, giving you a lightweight, flexible way to control any computer without extra peripherals.
