iPhone 15 Pro screen brightness issue after iOS 26 update

After ios 26 update when waking up the phone (iphone 15 pro), the screen brightness is very low. After unlocking the phone, screen remains dimm regardless of the light intensity. I have to lock and unlock phone again to make automatic brightness start working (and brighten the screen to level that allows me to use the phone). This doesn't happen every time but often enough to be annoying.

17PM here running ios26.2. Issue still persists. It's extremely annoying. I've tried every display setting change suggested and a few others I can find, and also resets, etc. It still does it. FIX THIS APPLE!

I've seen several comments in this thread about the 17PM doing it, but ok....... it's just one more way for Apple to ignore its customers. Got it, thanks....

I don't think you got it. We are not Apple, we are volunteers. If you want to talk about iphone 17 you are welcome to start your own thread

I get that you’re frustrated. But in multiple places users, like you and me, are alerted to the fact Apple does not participate here. You’re posting to other users, not Apple employees. Volunteers, like me and others, care enough about other users to try and point them to possible solutions to their issues.

I understand that you came here looking for solutions. I would too. Solutions lay with the links and information I shared. If you want solutions you have the path. If you came here to whine and express your frustration, we get it. I wish you nothing but the best and hope you can find a way forward that accomplishes your goals.
