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.

Hi, Apple Support Communities is not Apple Support. Apple and Apple Support do not participate here. Everyone posting, commenting and reading are fellow Apple users just like you.


I can address some issues you’re experiencing. Facebook scrolling is a FB issue. Their developers have not fully optimized the app for iOS 26 yet. FB has had 10 updates in last month. An update every 3 days should tell you how buggy their app is.


Liquid Glass can not be turned off. Every time Apple makes significant UI changes some like it some do not like it. Apple is making slight UI changes in response to feedback from users. Link is below to add your voice.


Scrolling on Home Screen is probably just an optimization issue. 26.1.0 will have improvements and optimizations.


Brightness dimming could be hardware or software. Either wait for 26.1 or have Apple do diagnostics. If 26.1 doesn’t resolve almost certainly hardware.

Little Update: I've reported the issue via feeback app already last year and have got an answer this week. It seems, it will be solved with an upcoming iOS release, hopefully with 26.3. This is what Apple answered:


Hello B,

Changes have been made that may have resolved this issue. If the behaviour persists, please send us a new feedback report so that we can investigate the issue further.

Thank you for your feedback.

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.

i have had the same since day one. I have also already tried restarting it many times and it works fine for like the first 10 unlocks after that, before starting to be dim again. I have also used recovery mode to reinstall (update) the phone's os again, but i havent tried fully wiping and reinstalling it as thats too much hassle. Hopefully this gets fixed as it’s super annoying.

Same issue on my iPhone 15 Pro Max as well, 26.0.1 did not correct. Seems to be something with the camera? When I have my phone sideways on the charge dock at night too, the standby display does not show on motion like it did prior to iOS 26. This is the alarm clock like display that shows when the phone is sideways on a magsafe charging dock. Anyone else experience this as well?


The brightness can adjust after a bit of time (10-20 seconds) but it does not always adjust.
