Don’t know if this occurs on iPhone as well, but I found these issues on several Android devices:
The App sometimes crashed after taking a picture, so that the photo is not stored, but more often the screen is not responsive anymore (the camera symbol faded out) but eventually the photo is transmitted (see screenshots of the spitting spider before and after taking the shot)
The frame jumps every time I click a picture. This was also consistently happening on different devices, but of the same brand. In the example, the phone was fixed, so any movement was prevented. The final photo is only shown for the fraction of a second, so it is already fading out, but I think the issue is clearly visible.
Can others replicate?
