The jelly screen on your tablet may be caused by screen frequency mismatch. When the refresh rate does not match the frequency of the screen, a jelly screen will appear. In this case, the user needs to modify the refresh rate of the tablet or monitor to match. If you don’t know how to change the frequency, you can try searching for relevant tutorials or asking for help from the manufacturer.

The jelly screen on your tablet may be caused by overuse. If you use your tablet for a long time, the screen may have problems such as jelly or flickering. This is because overuse can cause the screen's capacitors to overheat, which can lead to display issues. In order to avoid this situation, users need to appropriately reduce the frequency of using the computer for long periods of time and give the screen a break.

The jelly screen on your tablet may be caused by hardware problems. If the above two scenarios don't apply to you, it may mean that your tablet is experiencing a hardware failure. This requires you to seek professional technical support and may require replacement of the screen or other accessories. During this time, to protect your device, do not use your tablet or send it to a repair center.
