Why does the brightness fluctuate and exhibit slight flickering during manual/automatic adjustment of the Redmi Note 14 Pro+ 5G's brightness?
The slight brightness fluctuations and flickering you notice during manual or automatic brightness adjustments on the Redmi Note 14 Pro+ 5G are due to the high-frequency PWM (pulse-width modulation) used for brightness control. The phone employs a 1920Hz PWM to adjust brightness, which is effective for reducing flicker at low brightness levels. However, during the transition between high and low brightness, you can perceive minor changes in brightness. This is a normal phenomenon and part of the design to ensure smoother brightness adjustments. You can continue using the phone with confidence as it has undergone strict quality control.
