The screen is not sensitive due to the unclean screen:

Use a clean dust-free cloth to wipe the dirt and water stains on the phone clean, and the question is that I just restarted him and messed up by himself.

Answer: The failure of the capacitive screen is due to the local charge on the surface, which is commonly referred to as static electricity, which makes it impossible to judge whether there is a finger or other conductor (such as a capacitive pen) pressed on it. Dry in winter, the human body itself with static electricity may cause partial charge of the screen.
