The Xiaomi 15 has undergone strict professional inspection before leaving the factory, so you can use it with confidence.
If the Xiaomi 15 has a text smear when sliding the screen, please refer to the following details:
1. It is normal for the text to have a slight smear when you drag the screen of OLED products, so you can use it with confidence;
2. You can try to manually adjust the frame rate to a custom 120Hz or adjust the font to the thinner type, which will alleviate the problem;
3. A defective display panel or aging screen can also cause excessive ghosting. If your phone was dropped or exposed to moisture, it will affect the screen’s refresh ability.
