Diaa Elhimdi Updated by Diaa Elhimdi

The Sunmi T2s is a versatile Android-based POS terminal, widely used in retail and hospitality for customer transactions. Here are some common issues users encounter with the T2s model, along with simple troubleshooting steps:

1. Touchscreen Unresponsiveness

  • Issue: The touchscreen may become unresponsive or lag, often due to software glitches or hardware wear.
  • Troubleshooting:
    • Restart the device to fix temporary software issues.
    • Check for any protective screen cover that might interfere with touch sensitivity.
    • Ensure the screen is clean; use a microfiber cloth to wipe away debris or smudges.
    • If the problem persists, consider a factory reset (after backing up data) as a last resort, as it may be caused by corrupted software.
    • Verify that the Access point is connected and is well exposed (not covered, not facing downwards)

2. Battery and Charging Problems

  • Issue: The battery may not hold a charge, or the device might not charge at all.
  • Troubleshooting:
    • Use the original charger and cable, as third-party chargers may not deliver the correct power output.
    • Inspect the charging port and cable for damage, and try a different power outlet.

3. Slow Performance or Freezing

  • Issue: The device may slow down over time or freeze due to heavy usage or insufficient memory.
  • Troubleshooting:
Exit Kiosk Mode :
1. Press and hold the power button until a screen appears.
2. Click "Exit Kiosk" on this screen.
3. Enter the default code (usually 0000) when prompted.
4. The app will close, and you'll have full access to the device.

Remember, when you start the app again by pressing its icon, it will automatically relaunch in kiosk mode. For more information, click here.
  • 2. Clear cache and unnecessary data to free up memory.
  • 3. Check for any available system updates; outdated software can negatively impact performance.
  • If running multiple applications, consider limiting to essential apps only to reduce memory load.
  • In case any third party apps have been installed, please make sure to remove them, as the device is designed and optimized for a specific purpose/use case.
  • Restart the device periodically to help manage memory usage.

4. Network Connectivity Issues

  • Issue: Difficulty connecting or frequent disconnections.
  • Troubleshooting:
    • Verify the correct IP address is set up in the POS APP.
    • in case WLAN is Active, please make sure to turn if off. The screen must be connected via Ethernet at all times.
