iPhone XR camera starts shaking and makes a weird sizzling or crackling sound
Has anyone experienced this for no apparent reason? I haven't dropped it, recently added apps or updated before it started doing this. When I open the camera (rear facing) it's focuses initially and then within seconds starts shaking and I can hear a faint sizzling sound.
I've tried all of the common fixes except factory reset and reload, I guess that's next but I'm not that optimistic it will fix it.
Any help would be greatly appreciated
iPhone XR, iOS 15
