Flaky capturing

[Ghedeon]

Not every single click results in onPictureTaken() callback.

I'm not talking about throttling when you click too fast, as you can see, it's enough time between clicks. It's just skipped randomly.

OnePlus One, 6.0.1

TL;DR of this log: Capture, Skip, Capture

Looks like same issue is already reported for the official Camera2Basic sample app: https://github.com/googlesamples/android-Camera2Basic/issues/33

The issue is with your android device. The devices that do not support auto focus throw this error. You need to disable auto focus to get rid of this error.
