Please help. Video software of hardware issue during video recording?

[Lara512]

Hello. I have iPhone 13 Pro Max. I was making a video of my cat, with out of the box settings, nothing fancy, and it seems like the camera lost focus and then I hear slight lens movement, and the video became sharper. Is this known? Should I replace my phone while there is still time? I would appreciate your feedback! Thanks

Hi! It looks like the phone automatically regained focus of something within the frame (sorry, the attachment you posted doesn't work). This might happen when the ambience gets darker/brighter or you move the camera a bit to fast. Maybe you accidentally tapped the screen and that tap made the camera focus on something else?
