Thank you for your support of Xiaomi products. The phone undergoes strict professional inspection before leaving the factory, so you can use it with confidence. For OLED products, slight text ghosting is an inherent characteristic of OLED devices and is considered normal.
To alleviate this phenomenon, you can try the following methods:
1. Try to open [Settings] >> [Display & brightness] >> turn on [Light mode];
2. Go to [Settings] >> [Display & brightness] >> [Refresh rate] >> [Custom] >> tap [Refresh rate] and choose 120Hz manually setting the frame rate;
3. You can go to [Settings] >> [Display & brightness] >> [Font settings] to adjust the font to a finer setting to alleviate this phenomenon.
