Sorry guys, but your PWM measurements are a joke at this point. From your own graphs I can see around 15% dip (amplitude). Not 75%. Also, the frequency is likely 720Hz. Also, you're not testing the anti-flicker modes built into the smartphones. Bring those tests to some updated standard or just exclude them maybe? They're misleading
If you are looking for a comparatively inexpensive flip phone, you should take a look at the Motorola Razr 60. With its unusual concept, Pantone colors for the housing and high-quality features, it could be a good choice for trendsetters and photography fans. But has it improved enough on its predecessor?
