The OLED screen reflects "wave patterns" when it is off
The visible wave patterns on the bottom of the mobile phone screen are a normal phenomenon, which is due to the display screen being attached to the protective glass frame position through optical adhesive. The bending effect of the optical adhesive causes the wave patterns to be visible at a large angle of reflection when the screen is off, and it does not affect the display effect when the screen is lit up. You can confidently use your phone, as this phenomenon will not have any impact on its functionality.
