Why does the brightness adjustment on the Xiaomi MIX Flip result in flickering or uneven transitions during manual or automatic brightness changes?

Our phones undergo rigorous professional inspection before leaving the factory, so you can rest assured of their quality. We have adopted the new LTPO (Low-temperature polycrystalline oxide) technology, which allows adaptive refresh rates under different brightness and scenarios. To ensure display performance at low brightness levels, we use 480Hz low-frequency PWM dimming. During transitions between high and low brightness, you will notice slight brightness changes. This is a normal phenomenon due to the technology employed to optimize battery life while ensuring excellent display performance. We are constantly working on further optimizations to enhance your experience.
