If the touch screen automatically jumps and touches the screen, you can use the following methods to troubleshoot the operation:

1.If the problem of jumping or ghost hands occurs when charging only in a fixed place, it may be caused by the unstable power supply voltage, and it is recommended that you change the charging to another place (replace the power supply).

2.If there is a problem of random jumping and ghost hands when charging only with a third-party charging device, please use the standard charger and data cable to try to charge first, if there is no problem, it may be a problem with the third-party charging equipment; It is recommended that you use the original charger in scenarios where you need to charge and use touch control, and you can remove the protective case to improve the touch experience.
