No - I mean going into settings > accessibility > display & text size > auto-brightness and then toggle that to “on”. That has worked for me and for many others on this forum. For me, when I take the phone off the charger, while it may technically be down to zero brightness, the auto-brightness feature then kicks in and automatically turns it up as it should. So, it makes sense that that would make it work. However, I really don’t like auto-brightness and anyway, the phone clearly should not work like this.
