People who are on iOS 11 may have some trouble turning off the auto-brightness setting on their iPhone and iPad.

iOS 11 was released in September and is the software that came with the iPhone X. The update can be installed on Apple’s latest iPhones, including the iPhone 8 and 8 Plus, as well as other previous models.

Some users might be fine with how the auto-brightness works on their device, but others might not be as comfortable with how low or high the light on the screen display gets.

How To Turn Off Auto-Brightness On iOS 11, iPhone X

With previous iOS versions, users headed to Settings > Display & Brightness to turn the Auto-Brightness option on or off. However, the auto-brightness setting location has been moved from that spot in the iOS 11 update.

To turn the auto-bright on or off, users on iOS 11 (and iPhone X) can go to Settings General > Accessibility > Display Accommodations. The auto-brightness option is found between the Color Filters and Reduce White Point options.

After getting rid of the auto-brightness feature, users can go to the Display & Brightness section in Settings and manually choose how bright they want their phone’s screen to be. This can also be done in the Control Center on iOS 11. On the iPhone X, users can open the Control Center on iOS 11 by sliding down the screen from the top-right area of the home display. For other iPhone models on iOS 11, users can swipe up from the bottom of the screen.

The $999 iPhone X comes with an edge-to-edge OLED display. The bright and colorful screen could drain the device’s battery faster when auto-brightness is turned off. The disabling of the auto-brightness feature could also cause screen burn-in.

How To Turn Off True Tone Display Setting On iPhone X, iPhone 8

The iPhone X and iPhone 8 also brought True Tone technology to its display. The feature uses an advanced six‑channel ambient light sensor to adjust the white balance on the screen depending on the environment the phone is in, whether it’s a cloudy day outside, or if its inside a home with warm lighting.

True Tone is intended to reduce eye strain, but some users are not happy with the feature.

“Turning on Tru Tone makes all white pages yellow.  About 2/3 of the way to the yellow that night shift gives,” said one user on a thread on Apple’s support forum. “I ended up turning it off.  I have to admit, that on my iPad Pro 9.7, the True Tone Display is my favorite feature. However, on the iPhone X, in order to get a true white I have to tilt the phone away from me to induce the color shift that occurs with the OLED screen when viewing at off angles.”

“My iPhone X is also way too warm with True Tone turned on,” said another user. “It definitely does not match the light in the room I’m in. If I hold a white sheet of paper beside the phone, the paper looks white and the phone looks yellow.”

To turn off True Tone on the iPhone X and iPhone 8, users can go to Settings, then Display & Brightness and turn the option’s toggle off.
