The POCO F6 Pro undergoes strict professional inspection before leaving the factory, so please feel free to use it.
It is a normal phenomenon for the device with an OLED screen that the text has a slight image retention or color deviation when scrolling the screen. In a low-light environment, the color display of the OLED screen will have a slight difference at 120Hz and 60Hz.
You can manually adjust the refresh rate to 60Hz or 120Hz for your preference. Alternatively, you can turn off the dark mode, which will alleviate this phenomenon.
