That sounds like it can’t possibly be true, and yet a quick search later – indeed, even the Galaxy S26 Ultra relies on traditional PWM to adjust its brightness. Simplifying things a bit, in case you don’t know what we are talking about, PWM (Pulse Width Modulation) is the traditional way of… Samsung Galaxy S27 might finally introduce DC dimming.
