So I'm capturing frames from the camera preview, and I'm experiencing an issue on two of my phones where when the camera opens, it immediately gets extremely dark. I then have to tap the screen to get the phone to then exposure for the correct part of the image (the part I tapped). My other developers aren't experiencing this on their phone though. I'm having the issue on both an Xs and 11 Pro. The other developer has an Xs and doesn't have this issue.
For me, when the camera opens, it's fine for a split second, but then you see the camera preview immediately get super dark, as if it's automatically changing the exposure way too low. It's like if you were to open your camera facing a super bright window. The camera would immediately adjust exposure setting to expose the window, but leave everything in the room too dark.
The weird thing is that there is nothing bright in my view. I'm just pointing it at my face with a front facing camera. For some reason it thinks the view is super bright or it's getting the wrong light reading initially. If I then just tap on the screen, it immediately adjusts and exposes how it should.
I'm totally stumped. It's happening on both of my phones, but not his.
