You can follow the steps in this guide to upgrade the firmware and resolve these issues. Additionally, the firmware upgrade will help calibrate the touchscreen and adjust its sensitivity (either increase or decrease).

3. Open the TouchUtility app, select “Firmware Upgrade,” then choose the firmware file you prepared earlier and click “Upgrade.”
