Iphone 12 pro max audio and screen brightness issues since updated to new iOS (26.1)

Iphone 12 pro max is having audio and screen brightness issues since updating to iOs26.1. The audio goes down on every app I use. A notification shows up the audio goes down. I click on a song to listen to it, the audio goes down and so on. The screen’s brightness keeps on trying changing every few seconds…all of this started when I updated to the latest iOs. Is there some way to fix all of this?
