Thank you for your support of Xiaomi products. The POCO F7 Pro undergoes strict professional inspections before leaving the factory, so you can use it with confidence.
If you notice this phenomenon when using the phone, please refer to the following information:
1. If the screen stays on one interface for a long time, there will be a certain amount of image residue after switching to other interfaces. This is an inherent characteristic of the OLED screen and is a normal phenomenon;
2. This phenomenon will gradually disappear with the normal use of the device. It is recommended that you avoid using it on the same interface for a long time to get a better usage experience. We appreciate your understanding and continued support.
