Screen is dimmed after unlocking iPhone

Question

Level 1

4 points

The screen is dimmed when I unlock it. Then after a few seconds it makes the brightens up and goes normal.

The letters even look ghosted when the phone is unlocked, then they go normal and sharp and the screen brightens up a little.

Here is a video example. ( I uploaded to YouTube because I can't attach a video )

iPhone 5s, iOS 12

Hello iñaki97,

Thanks for asking the Apple Support Communities for help with your iPhone. Thanks for the video example as well.

If you have Automatic brightness enabled, I recommend disabling it, restarting, and then testing. Restart your iPhone - Apple Support

Test with Auto-Brightness enabled and disabled. If it is currently disabled, enable it, restart, and then disable it again, then test.

Your info shows iOS 12, so you can turn Auto-Brightness on or off in Settings > General > Accessibility > Display & Text Size.

For devices with iOS 13, you can turn Auto-Brightness on or off in Settings > Accessibility > Display & Text Size

Also, ensure there is nothing blocking the ambient light sensor on your device. Some third-party screen cases and screen protectors may block the sensor. You may need to remove them and test again. Get help with the display on your iPhone, iPad, or iPod touch - Apple Support

Thanks and have a wonderful day.
