Why does the phone screen operate automatically and the screen jumps around?

Explanation：

Screen jumping, automatic operation is not necessarily caused by screen damage, it is recommended to take into account the use of the environment and so on.

Most devices currently use capacitive screens. Capacitive touch screen technology is the use of the body's current induction to work, some of the following factors may affect the use of capacitive screens.

1, too high and too low temperature: capacitive screen is more sensitive to temperature, too high or too low temperature will affect the capacitive touch, you can first confirm whether the phone is used in an abnormal temperature environment.

2, there are water droplets or moisture: water droplets touching the touch area will also cause changes in the current, hands with sweat or water droplets and then touch easy to form a conductive layer on the screen and drift, jump screen. Even lying under the blanket in winter, the phone outside the blanket, due to the screen temperature is very low, breathing heat and a slight moisture attached to also cause changes in the current, resulting in automatic touch problems.

3, near the magnetic field: speakers and other magnetic things may make the capacitive screen failure, do not often contact magnetic objects.

4, unstable charging voltage: when charging the phone, if the charger or socket generates abnormal voltage, the capacitive screen will drift in the case of unstable transmission voltage. This situation is manifested as a jumping screen and automatic touch phenomenon when charging, normal when not charging. It is recommended to replace the charger, replace the charging plug and socket to try.

5, electrostatic shock more powerful: some lower-end led lamps, lampshades may generate static electricity, winter human body or clothing prone to static electricity, computer USB interface near static electricity may also be stronger. Static electricity can easily break through the capacitive screen of the mobile phone, resulting in abnormal touch recognition, jumping screen and other problems. It is advisable to observe whether there are things in the environment that are prone to static electricity.

Note：

If environmental factors have been investigated and the user has been instructed to restore the factory and the problem persists, it is recommended to request an after-sales service.
