That being said, this feature soon to be called a bug, feels like one of those things being done in the name of performance. I do not agree with this solution, however, the startup time for the camera on older iOS devices can be frustratingly slow. My 6S now on iOS 13 can take several seconds for the camera to turn on. This is most evident when trying to capture something in the moment on Snapchat. The stock camera app takes long enough that I often miss key moments (I plan to upgrade soon, but have not yet committed to losing my headphone jack).
I’m not at all excusing this, but I can see why they’d try this if they want their users to post more original content
