The status bar position of OPPO mobile phones cannot be changed. The time, position and color of the mobile phone lock screen are set by the system and cannot be customized. However, the time and position will automatically change according to the lock screen style. ColorOS 11 has been optimized based on the screen clock and added a new screen style. ColorOS 12 brings more colorful screen styles, such as plain text personalized signature, picture and text combination, dial clock, Omoji and art album, etc. You can also perform personalized hand-painting to create your own exclusive screen pattern. You can even turn photos of your parents, children, relatives and friends into a portrait screen pattern. Setting method: Here we take the OPPO FindX3Pro mobile phone ColorOS 11.2 version as an example: "Settings > Personalization > Screen Style". Warm reminder: ① The screen-holding clock is related to the hardware, and some models do not have the screen-holding clock function. Thank you for your attention and support. ② Omoji and art albums will be updated with the subsequent ColorOS 12 version. Please pay attention to the OPPO community for specific upgrade plans. Due to different mobile phone system versions, the operation path may be slightly different. Please refer to the actual operation interface display of the mobile phone. This answer applies to all OPPO models.
