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.

Try and force restart the iPhone to see if the issues persist

Press and quickly release the volume up button. Press and quickly release the volume down button. Press and hold the side button.When the Apple logo appears, release the side button.

I'm having the exact same issue on my iPhone 15 Pro Max since I upgraded to iOS 26. Nearly half the times I unlock my phone, it's too dark, so I have to lock and unlock it again so it's bright enough to see.

The brightness is always fixed after the second unlock, but this is very frustrating.

I have toggled all the settings off/on that everyone has said to and forced a restart. The only thing I haven't done is a factory reset of my phone and I'm really hoping it doesn't come to that.

Same issue with my 15 Pro.

I do not use “always on display” if that matters.

This bug is extremely annoying.
