If you are playing an online video, it may be caused by:
1. Network connection problem: Please check whether the current network is smooth, or try another network, or you may reduce the resolution of the video file you are currently playing
2. Insufficient system resources: If the memory space is insufficient and there are too many programs running in the background, it is recommended that you clear the cache or delete useless files to free up more memory space and close unnecessary applications running in the background.
It is recommended that you change other video clients, or change the network of a different operator (the video provider may provide different acceleration servers for different operators), or change the time period and try again.
If you still can't solve it, please try the system freeze solution.
1. Maybe the effect of the source file itself is not good. It is recommended to change the video source and try to play it again.

Possible causes and solutions:
1. The impact of non-standard chargers: When using non-standard chargers to charge, if you change the charging to using a mobile phone, abnormal charging may interfere with the touch screen and cause the touch screen to respond to a jump screen. It is recommended to unplug the charger and try again.
2. Environmental impact: In an environment with high humidity (such as a bathroom), due to the abnormal response to the capacitance of the touch screen, it may cause problems such as screen jumping. It is recommended to try again in a normal environment.
In this mode, the sensitivity of the touch screen will be greatly improved. If it is used without gloves, the user may have the illusion of jumping the screen because it is too sensitive. It is recommended to turn it off under normal circumstances.
Please make sure that both the mobile phone software and third-party applications are updated to the latest version. Some third-party applications have design problems that may create the illusion that the touch screen is not sensitive. You can refer to the evaluation of the application market.
3. If there is still a problem, please back up your personal data and take the purchase certificate to the after-sales service outlet for maintenance.
