The Galaxy S26 Ultra, Samsung's latest flagship, has sparked a debate about display technology and accessibility. While the Privacy Display feature is innovative, it also highlights a glaring omission: the lack of eye-care features to address display flickering, a problem that has been solved by cheaper Android devices for years.
The Flickering Issue
Pulse Width Modulation (PWM) dimming, a common method to control display brightness, can cause discomfort and even migraines for some users. Lower PWM frequencies are associated with eyestrain, headaches, and nausea, and this issue is exacerbated at lower brightness levels.
Samsung's Missed Opportunity
Samsung could have easily implemented higher PWM frequencies, as demonstrated by brands like HONOR and OPPO. Even budget smartphones offer higher PWM rates, yet the S26 series lags behind with a low 480Hz rate. Samsung could have also adopted DC-like dimming or introduced software features to reduce flickering, as seen in devices like the Xiaomi 15 series and the OnePlus 13.
Accessibility and Transparency
Display accessibility is not a niche concern. Photophobia, or sensitivity to light, affects a significant portion of the global population, especially those with migraines. Megan Ellis, a chronic migraine sufferer, highlights how flicker reduction is essential to prevent migraine attacks and reduce eye strain. Many people may not even realize that their eye strain is caused by their phone's PWM rate.
The lack of transparency and accessibility options is a major oversight. As the world's largest Android smartphone company, Samsung should lead by example and provide users with the information and features they need to make informed choices.
A Step Towards Progress
While Samsung has yet to address this issue, there is hope. The awareness and advocacy around display accessibility are growing. Brands like Xiaomi and OnePlus have taken steps to improve their devices, and Samsung could follow suit.
In my opinion, the S26 Ultra's Privacy Display feature is a step in the right direction, but it's not enough. Samsung needs to prioritize accessibility and transparency, ensuring that its devices cater to a wider range of users. Until then, the company will continue to lag behind in an area where even budget smartphones have made significant progress.
