While allowing your iPhone to automatically adjust the brightness of your screen can be a useful option, you may find that the screen is just brighter or darker than you would prefer.

It’s probably a good idea to disable the auto-brightness setting in cases like these.

If you disable auto-brightness on your iPhone 14, you can adjust the screen brightness manually by navigating to Settings > Display & Brightness and dragging the Brightness slider to the right to make the screen brighter, or to the left to make the screen dimmer.

Swiping down from the top-right corner of the screen to access the Control Center, then dragging the Brightness slider on that menu instead, will allow you to alter the screen brightness.
