Smart invert

Hello iva135,

Thank you for reaching out to Apple Support Communities.

You may be enabling it using a shortcut. These steps should help:

"Triple-click the side button or Home button

With Accessibility Shortcut, you can quickly turn on or off accessibility features by triple-clicking the side button (on an iPhone with Face ID) or triple-clicking the Home button (on other iPhone models).

• Set up Accessibility Shortcut: Go to Settings  > Accessibility > Accessibility Shortcut, then select the features you use the most.
• Slow down the double-click or triple-click speed: Go to Settings > Accessibility, then tap Side Button or Home Button (depending on your iPhone model).
• Use Accessibility Shortcut: Triple-click the side button or Home button.

See Adjust settings for the side or Home button on iPhone."

More details can be found here: Use accessibility shortcuts on iPhone

If the issue persists, can you provide a few more details? When did you first notice this? What is your exact iOs version? Also, how often does this happen?

Cheers!

Hey iva135,

Since this continues after checking the settings from the previous reply, this may be something that Apple needs to look in to further. You can reach out directly from Apple Support.

All the best.
