AMOLED PWM Ranges
KM Because we discovered that AMOLED smartphones are potentially usable when PWM is turned off (and the OS is friendly), I looked up notebookcheck.com's AMOLED reviews that claim PWM is only used at low brightness levels. These are the results so far (I cut the list at 40%):
Acer-Liquid-Jade-Primo-Smartphone: 238.1 Hz up to 23% brightness
Google-Pixel-XL-Smartphone: 238.1 Hz up to 23% brightness
HP-Elite-x3-inkl-Lap-Dock-Phablet: 357.1 Hz up to 31% brightness
Lenovo-Moto-Z-Play-Smartphone: 243.9 Hz up to 20% brightness
Lenovo-P2-Smartphone: 240.4 Hz up to 20% brightness
OnePlus-3-Smartphone: 243.9 Hz up to 10% brightness
OnePlus-3T-Smartphone: 244 Hz up to 10% brightness
OnePlus-X-Smartphone: 237 Hz up to 25% brightness
Samsung-Galaxy-J1-2016-Smartphone: 238.1 Hz up to 30% brightness
Samsung-Galaxy-J3-2016-Duos-Smartphone: 238.1 Hz up to 38% brightness
Samsung-Galaxy-J7-2016-Smartphone: 238.1 Hz up to 40% brightness
ZTE-Axon-7-Mini-Smartphone: 238.1 Hz up to 20% brightness
If anyone wants to try AMOLED phones, those are probably our best bet at the moment. Please let me know if you know of other sites that test for AMOLED PWM.
APK to simulate 100% brightness (to remove PWM dimming)
WooteverXDA Hello, a few days ago i switched from a Nokia 6.1 to a Samsung Galaxy S9+, unfortunately the still present 240hz PWM flicker makes it unusable for me.
However, i noticed that constrast dimming via a transparent overlay leads to almost the same result as a manually adjusted pwm control in the display kernel driver would.
Here is a small application that dims the brightness with a accessibility overlay, effectively removing pwm (measured on lowest brightness):
This is mostly tested on a Galaxy S9+ but should work for every AMOLED device that doesn't utilize PWM at 100% brightness.
I would be very interested in feedback and/or bugreports from other devices, thanks.
