Weird glitch in camera

I have encountered what seems to be a glitch of some sort in the camera app. It’s hard to explain but it’s like the camera is switching to one lens and then back very quickly. It usually happens when switching between 1x and 2x zoom but also sometimes when focusing in 2x zoom mode (shown in the second video). Does anyone have any idea what’s causing this or if something is wrong with my phone? I have an iPhone 12 Pro.

I don’t know if you can upload videos here so I uploaded 2 example videos on Youtube showing my issue.
