1. Check for software updates: Make sure your iPhone is up to date with the latest iOS version. Sometimes, software updates can address bugs or issues related to screen brightness.

2. Check display settings: Navigate to Settings > Display & Brightness and ensure that the brightness level is not set too low. You may also want to toggle off features such as Night Shift and True Tone, as these may affect screen brightness.

3. Disable automatic time zone: Go to Settings > Privacy > Location Services > System Services, and turn off "Setting Time Zone." This feature can sometimes trigger changes in screen brightness based on your location.

4. Reset all settings: If the issue persists, you can try resetting all settings on your iPhone. This will revert your device to its default settings while keeping your data intact. To do this, go to Settings > General > Reset > Reset All Settings.

5. Restore or update via iTunes: If none of the above steps resolve the issue, you can try restoring your iPhone through iTunes. Connect your device to a computer, open iTunes, select your iPhone, and choose the option to restore it to factory settings. This will erase all data on your iPhone, so make sure to back up your device first.

Note: If the problem still persists after trying these steps, it might be worth contacting Apple support or visiting an authorized service center for further assistance.
