Thank you for your support of Xiaomi products. This is normal and you can use it with confidence. The phone has been strictly inspected before leaving the factory, which makes the phone meet the specification requirements of Xiaomi products.
For your reference, here are the reasons for the display difference between the POCO F7 and the POCO F7 Pro:
1. Due to normal process fluctuations in the production of mobile phones, there will be slight color differences between the two mobile phone screens when you view the screen at a straight angle or tilted angle;
2. You can also go to [Settings] >> [Display & brightness] >> [Color scheme] >> adjust the point position in the color temperature adjustment area according to your preference.
