Brightness

Are you suggesting that the iPad screen brightness changes regardless of your iPad settings?

To disable automatic changes to screen brightness and colour balance, ensure that TrueTone is disabled:

Settings > Display & Brightness > True Tone - set to OFF

A forced restart of your iPad might be helpful - as doing so will often resolve an isolated software issue:

• On an iPad with a Home button: Press and hold the top button and the Home button at the same time. When the Apple logo appears, release both buttons.
• On other iPad models: Press and quickly release the volume up button, press and quickly release the volume down button, then press and hold the top button. When the Apple logo appears, release the button.

You are welcome.

What model of iPad do you have?
