Hello -Vonte- and welcome to Apple Support Communities.
It appears you are having some difficulty with focus on an iPhone 12.
If this is an iPhone 12 Pro Max, keep in mind that the larger sensor means a longer focal length which may make items very close to the iPhone photograph as blurry.
Also, some magnetic accessories can pull the camera out of focus.
If there is no case or other accessory attached to the iPhone and focus remains an issue, you'll want to arrange to have someone do camera diagnostics which does require going to an Apple Store or Apple Authorized Service Provider.

Cheers.
