i've tried again on TV app and it didn't reproduce but without bringing control center and turning the phone from one landscape to the other makes the screen flicker for a sec.. that's really weird ....
BUT now i know for sure it is software cos i added a movie on VLC, and in landcape moving brightness , changing landscape orientation , i wasn't able to reproduce the issue... so it's a strange bug that for sure will be fixed soon for those like me who still have it somtimes on particular occasions... the bad news is that i've ordered a 9th iphone 12 pro max this afternoon , to try to push my luch thinking maybe i'll get aunit that was produced in january or february.. and it's already on it's way.. so i'll keep you guys posted if the new one is better , 100% fixed out of the box, or worse than the one i have.
i wonder if apple will not send me an email like ' dear customer we noticed that you returned to us a ton of iphone 12 pro max , please be careful cos we will not accept future returns... like amazon does to some customers who have a retun rate to high...
i've phones apple this afternoon asking them if i was to order a new phones i had more chances that this issue would be fixed, but the person i had was so bad, i told her that apple aknownleged the issue on public beta 14.5 beta 2 notes, and she told me that they didn't know about this, that it must be me, i was so angry at one point that i hang up on her.... sometimes some employees are not fit and up to date with the info... nut usualy they are efficient i must say.
have a good week end.
