Our product has a layer of plastic protective film applied to the screen during manufacturing, which can be peeled off.

Please first try replacing the SD card and restarting the device. If the issue persists, the display flex cable may have been affected by moisture. Please clean the display flex cable with alcohol. If the issue is caused by physical pressure damage to the screen, the display or the entire device will need to be replaced.

Please check whether the power indicator light turns on. Charge the device for about 30 minutes and check if the battery is damaged.

• If the light turns on after charging, the battery is functioning properly, and the issue may be with the screen.
  
• If the light does not turn on, try removing the back cover, disconnect the battery, and connect the charging cable.

• If the light turns on and the screen powers up, the problem is with the battery.
  
  If the screen still does not turn on, the motherboard may be faulty, although battery issues cannot be completely ruled out.

If the power indicator lights up, the motherboard should be fine, and the issue is likely with the screen. Try reconnecting the display flex cable.

If the problem persists after ruling out the motherboard and battery, please contact us via email.

Please open the back cover of your device and check whether the magnet inside the hinge has fallen out. If the magnet has come loose, simply place it back into its original position and the issue should be resolved.

If the magnet is still in place and the problem persists, please contact our support team for further assistance.

This issue can sometimes occur due to slight misalignment of the screen frame during assembly or use.

Suggested solution:

First, please try the following method:

Carefully press along the edge of the screen frame, starting from an area where there is no light leakage, and gradually move toward the area where the light is leaking. This helps gently realign the frame into place. Please repeat this process several times. Moderate pressure may be applied, but please take care not to damage the screen.

If the issue persists:

If pressing does not resolve the issue, you may try the following:

• Remove the screws located around the screen area (These screws are covered with silicone screw caps)
• Carefully remove the screws and separate the shells of the device
• Reposition and properly align the screen
• Reassemble the device and ensure all screws and covers are securely installed

Please proceed carefully during disassembly to avoid any damage.

2. Select Calibration to recalibrate your joystick.
   
3. Select Key Map to reset button assignments.
   

After completing these steps, the buttons and joystick should function normally.

When inserting the SD card into the slot, please use your fingernail or a thin object to gently push the card further in. Simply pressing it with your finger may not be sufficient.

When the SD card is properly inserted, you should hear a clear “click” sound, which indicates that it is securely in place.

Please first go to Hardware Test in the settings and check whether there is any response.
If there is a response, the button itself is not faulty. You can try disassembling the device and adjusting the corresponding rubber pad under the button.

Before starting, please make sure both devices meet the following conditions:
