What is the reason why the screen of OPPO mobile phone flickers, the page jumps by itself, and the touch screen is messed up?

If your phone’s screen flickers, it is recommended that you try the following methods: 1. Turn off the automatic adjustment function of the phone’s screen brightness; 2. Turn on certain content in the developer options, such as turning on CPU rendering and other switches. Close; 3. Uninstall and delete recently installed software (excluding whether the screen flashing phenomenon is caused by the downloaded software being incompatible with the mobile phone); 4. Back up important data (contacts, multimedia files, etc.), and then restore factory settings. If the problem still exists after performing the above operations, please bring your purchase invoice, warranty card and machine to the OPPO Customer Service Center for testing, and a professional engineer will solve it for you.
