Why does the edge of the screen on the Xiaomi 14T Pro appear bright?

The Xiaomi 14T Pro has undergone strict professional inspections before leaving the factory, ensuring that you can use it with confidence. 
In dark environments, the bright edge is a result of the extremely narrow frame structure surrounding the display. This phenomenon occurs when light reflects off the edges of the screen, creating a bright appearance. It is a normal occurrence and does not indicate any malfunction or defect in the device. You can use the phone with confidence, knowing that this is simply a characteristic of the design rather than a failure. If you find the brightness distracting, consider adjusting your viewing conditions or using the phone in a well-lit environment. This will help mitigate the effect and enhance your overall using experience.
