Common Reasons Square Register Touchscreen Stops Responding
- Overheating after long periods of use
- Software crash in the Register OS
- Static electricity buildup on the display
- Loose or faulty power connection
- Corrupted cached data in the Square POS app
- USB accessories (scanner/printer) interfering with system performance
How to Fix Square Register Touchscreen Not Responding
1. Restart the Register (Fastest Fix)
A quick restart resets the OS and clears frozen processes.
- Hold the power button for 3 seconds
- Tap Restart
If the screen is totally frozen, hold power for 10 seconds to force reboot.
2. Clean the Touchscreen (Static or Moisture Can Cause Ghost Touches)
Moisture, grease, or static can block touch responsiveness.
- Use a dry microfiber cloth
- Wipe gently in circular motions
- Avoid cleaning sprays directly on the screen
Even a small smudge can make taps stop registering.
3. Check for Overheating
If your Register feels warm, the touchscreen may slow or freeze.
- Turn off the Register for 5–10 minutes
- Move it away from direct sunlight or heat lamps
- Ensure vent openings aren’t blocked
Heat is one of the most common causes of touchscreen lag.
4. Disconnect USB Accessories
Faulty scanners, printers, or cash drawers can cause freezes or input delays.
- Unplug all USB accessories
- Restart the Register
- Reconnect accessories one at a time
This helps identify whether an external device is causing the freeze.
5. Check Power Cable and Outlet
If the Register isn’t receiving stable power, the touchscreen may become unresponsive.
- Ensure the power brick is seated correctly
- Try a different outlet
- Avoid using extension cords or power strips
A loose or low-voltage connection can cause random freezing.
6. Update the Register Software
Square regularly fixes touchscreen bugs with OS updates.
- Go to Settings → General → About
- Install available updates
An outdated OS is a leading cause of touchscreen glitches.
When to Contact Square Support
- The screen freezes multiple times per day
- The Register won’t restart or stays stuck
- Touch points register incorrectly (ghost touches)
- You see physical damage or discoloration on the display
