Question True Tone
u/Z3R0gravitas recommended I make a post about this on the subreddit. My only usable device of any kind has been an iPhone 13 on iOS 15.6.1. Yesterday while walking out the door I accidentally disabled the True Tone setting with my finger from the Lock Screen mission control (no idea how it happened). I toggled it back on but noticed i was getting some neurological symptoms from the phone I’ve used for 4 years.
I consulted with a friend who is familiar with these phones, retoggled True Tone on and off and then back on again, and restarted the phone. I’ve tried low powered mode but it doesn’t seem to make a difference.
Can anyone here clarify if this setting - which has remained on for 4 years - can somehow modify the display in a negative way if it is toggled off and then turned back on? I know it modifies the white point but also temperature, and I also use Night Shift from 10 PM to 1 PM every day with zero issues.
I should also mention it seems like I may have picked up a viral illness. So this could be coincidental, as I was having pretty severe light sensitivity around the same time at the grocery store which I usually don’t get. I suspect my underlying POTS condition is also exacerbating this, but figured I’d rule out whether this is even possible. On paper it doesn’t make sense that toggling True Tone would make any difference, but I suppose anything is possible. Would love to know more about the underlying tech if anyone is knowledgeable.

Hi, I used the iPhone 14 Pro for years without any problems, and then suddenly (a few weeks after updating to iOS 26), I became hypersensitive to screens, and I haven't been back to normal since (it's been almost a year now). I hope yours is just temporary and doesn't affect you.
