Hello idontreallyknow342,

It sounds like you may have an accessibility shortcut enabled on your iPhone. For help with checking the current settings of this feature, use the steps below found in the article here: About the Accessibility Shortcut for iPhone, iPad, and iPod touch

"Use the side or top button

If your device doesn't have a Home button, it has either a side or top button.

If you have a protective case on your iPhone that may cover or involuntarily enable this feature, test with the cover temporarily removed. You can also find helpful information here: Use accessibility shortcuts on iPhone

With Switch Control check your settings with these steps to see if a third-party Bluetooth device or gesture is enabling the feature: Use Switch Control to navigate your iPhone, iPad, or iPod touch

Cheers.
