Why does the screen of the POCO X7 Pro stay on one screen for a long time, resulting in image retention when the screen switches?

Thank you for your support of Xiaomi products. All phones undergo rigorous professional inspection before leaving the factory, so you can use them with confidence. Due to the display characteristics of AMOLED, the phone will show slight visual changes after long-term use, including "image persistence" or "burn-in", which means that even after you switch to a new image on the screen, the display will show a faint residual image. This is a screen effect, not real damage or aging. You can further reduce the "image persistence" or "burn-in" effect by reducing the screen lock time, occasionally adjusting the desktop icon layout, and automatically switching wallpapers.
