4. Installation Guide
Follow these steps carefully to install your GuliKit Hall Effect Joystick Module. A small Phillips head screwdriver and a plastic prying tool (spudger) are recommended.
- Step 1: Turn Off Steam Deck OLED
Ensure your Steam Deck OLED is completely powered off before beginning the installation process.

- Step 2: Open the Back Cover
Carefully use a prying tool to open the back cover of your Steam Deck OLED. Refer to online guides or videos for the precise locations of clips and screws if you are unsure.

- Step 3: Remove the Joystick Module Cable
Locate the existing joystick module and carefully disconnect its ribbon cable from the ZIF connector on the mainboard. Use tweezers or a plastic tool to gently lift the connector's locking tab before pulling out the cable.

- Step 4: Remove the Original Joysticks
Unscrew the retaining screws that secure the original joystick modules to the Steam Deck's internal frame. Once unscrewed, carefully remove the old joystick modules.

- Step 5: Install GuliKit Joystick Module
Place the new GuliKit Hall Effect Joystick Module into position. Plug its ribbon cable securely into the ZIF connector on the mainboard and lock the tab. Then, secure the module with the retaining screws.

5. Operating and Calibration
After installation, it is crucial to calibrate the joysticks for optimal performance.
5.1. One-Button Calibration
Perform this calibration before securing the back cover of your Steam Deck OLED.
- Move the joystick to the symmetrical position of the central point (e.g., push it fully in one direction, then release).
- Press the tiny calibration button located on the joystick module's board.
- Release the joystick.
- Calibration is successfully completed when you observe the joystick return to the center position.

5.2. Reducing the Dead Zone
The Hall Effect joysticks are designed to minimize controller dead zones. You can further fine-tune settings within your Steam Deck's operating system to potentially achieve a zero dead zone, allowing for more responsive input and reducing issues like stick drift.
6. Maintenance
To ensure the longevity and optimal performance of your GuliKit Hall Effect Joystick Module:
- Keep the joystick area clean and free from dust and debris.
- Ensure the stick caps are securely pressed down, as they can sometimes become loose during shipping or handling.
- Avoid excessive force or impact on the joysticks.
7. Troubleshooting
If you encounter any issues with your GuliKit Hall Effect Joystick Module, consider the following:
- Joystick Not Centering: It is normal for the joystick not to return to the absolute center each time when operating in a 'no dead zone' mode. This is a characteristic of highly sensitive joysticks designed for minimal dead zones.
- Stuck Joystick Cap: If a stick cap feels loose or stuck, gently press it vertically downwards to reseat it properly.
- Calibration Issues: If the joystick behavior is erratic after installation, repeat the one-button calibration process (Section 5.1). Ensure the joystick is moved to its symmetrical position and released before pressing the calibration button.
- General Performance: If issues persist after calibration and checking physical connections, ensure all ribbon cables are fully seated and locked in their connectors.
