Thank you for your support. Each phone undergoes strict professional inspections before leaving the factory, so you can use it with confidence. OLED screens use a combination of DC and PWM dimming. DC dimming is a technology used in displays to control brightness by varying the direct current (DC) flowing to the screen. PWM dimming, or pulse-width modulation dimming, adjusts screen brightness by rapidly turning the display on and off at different intervals. This method helps reduce flickering at lower brightness levels, which can be easier on the eyes, especially in low-light conditions. The DC dimming can lead to uneven brightness in lower-light environments. This is a normal characteristic of OLED displays. You can adjust the color scheme in settings.
