My Pixel 6a flickered really crazy, It sometimes even felt like the screen was running at 30 or even just 10 Hz at the lowest brightness in a complete darkness. The flicker was noticeable while shaking the phone and paying attention only to the display. For the ambient display, once the only red pixels turn on, the flicker is just noticeable with a bare eye. I know the a-series is supposed to be a mid-range and more budget friendly, but Google could do better with the OLED panel.

Wow... Love the visual comparison. I have one suggestion for future updates on this pwm update each year. Create 5 brightness levels testing and level them on the video screen: 95%, 75% 50% 25% 10%. This makes it so easy to compare.

My settings is Reduce White Point on 87% for indoors(usually 40-100% brightness), true tone on and dark theme. For outdoors RWP is off. Maybe it’s helps for someone. P.S.

All the Chinese who allegedly have a high PWM frequency are nothing but marketing. This frequency is turned on at low brightness, in other modes they operate at a frequency of 120 Hz. While the iPhone and Samsung operate at 480hz frequency over the entire brightness range. Therefore, it is much easier to transfer

[@PeterB12345]

Well the blue light issue can be addressed with screen filter apps, or if that doesn't work, you can get a pair of glasses with the special FL-41 coating. This will filter out the wavelengths of blue light that have been found to be harsh to the eyes. Theraspecs makes nice FL-41 prescription lenses. They do look a bit pink though, so you might not want to wear them at all times.
