I think you are overstating the delay involved in taking a photo and having it process inside Android. Whether or not you're taking a screenshot of the viewfinder or properly processing the photo, the moment you press the shutter button is the exact moment that Android captures what the camera sees. The processing that goes inside may take a second or so (if you're using the camera API) but it's fairly negligible in the long run. Any other app on Android that properly uses the camera - whether it's a built-in camera app or something third party like Facebook, Instagram, OpenCamera, Snapseed, etc - it's not like you're waiting 15 seconds for an image to process. It's all fairly quick and seamless. The excuse of "oh it's just for quick sharing so we don't have to focus on quality" is a strawman argument that doesn't really work, because the tech is there to allow it to function both beautifully and quickly - they just don't put the resources into making it happen.

I think it can take a hundred milliseconds or more to actually capture. It has to switch the camera from preview mode to capture, which involves a change in resolution, encoding and perhaps recalibrating white balance and automatic gain. So press the button and hold for a beat, or when you release the button you make shake/blur the image at the moment of capture.

  None of these performance hits sound like they negatively affect the purpose of the app though, at least not detrimentally to the point where poeple would complain about it. I am but one person, but there are far more complaints about the quality of the photos, than the milliseconds of lag you see hitting the capture button.

Using the stock camera app on my unmodified LG G6, this is just not true. There's about a second of lag between pressing the button, and actually capturing photons. Trying to capture my son in a specific pose is basically impossible. Maybe I'll download an app that screenshots a live video, rather than using the camera API, or whatever it's doing.
