Backcamera doesn't focus on big distance anymore

I dropped my phone a few days earlier. Now I noticed that the backcamera can't focus on big distance anymore. You can see, that it try to focus. It moves.

I'm not sure if this comes from the crash, because the camera does work normaly on close objects and the display is unbrokenly.

Any experiences with this?

Thank you for answers!

Sounds like you busted something internally or at the very least jiggled the camera lose enough to cause it to not focus properly.
