Has anyone else has this issue? Asking as the last two iphones I've owned have been ridiculously low in screen brightness. I've been through all the settings i should have them on, on ChatGpt. Last one just intermittently went from dark to readable; this one is barely readable outside at all right now and i'm sitting in the shade. Both have had heating up issues as well. No particular reason for the random heating up either. (Oh and BOOM - screen just became readable again) Infuriating.
