Three minutes into checking Google Maps on a sunny sidewalk, my Galaxy S25 dimmed to the point I couldn’t read it. The phone boasts 2,600 nits of peak brightness, which should overpower afternoon sun, but dragging the manual slider to maximum did nothing. For weeks, I assumed the sun was just too strong for any phone to handle, or that my display panel had a defect. The hardware was fine, but a built-in software safeguard was throttling panel output the entire time. Reclaiming the screen I paid for meant hunting down a single buried toggle that Samsung refuses to put in the main settings app.
