The touchscreen is an important part of any modern device: smartphone, tablet, laptop or ATM. If it does not work correctly, it can cause freezing, false positives or no response to touch.
Manual test
Swipe your finger or stylus across the entire screen to test the response. Please note:
- Missed touches
- Spontaneous activations
- Uneven multi-touch activation
What to do if the touch screen does not work?
- Restart the device — sometimes the problem is solved by a simple restart.
- Remove the protective film/glass - they can interfere with correct operation.
- Update the firmware — software errors can affect the touch screen.
- Calibrate the screen (if there is such a function).
- Contact the service — if the problem is hardware (broken display, damaged cable).
