Touchscreen failure
1. Keep your hand and touch screen clean and dry. Otherwise, the touch screen may not respond.
2. If the mobile phone is being charged and the touchscreen cannot respond due to the impact of current, try to use the standard charger. If the touchscreen still does not respond with the standard charger, stop charging the handset, and then check whether the touchscreen responds.
3. If the touchscreen does not respond when a third-party application is operating, the fault may be caused because the third-party application is incompatible with the mobile phone. Uninstall the application or back up important data, and then restore the factory settings.
4. If no response is received from the same position on each screen during different operations, it may be caused by bottom-layer driver faults, touchscreen faults, or other faults. Please carry the purchase invoice to the service office for repair.
