Backspace to move from photos to camera

In an effort to making the phone even more smooth, it is possible to consider the addition of a "Backspace" button addition that brings you back to the Camera app. I'm suggesting this because you can press "Backspace" to get from the Camera app to the Photos app, but it isn't a simple click of a button to return to the latter (back to the Camera app). If possible, make it so that hitting backspace from the Photos app saves the position you are at within your photo album as well, even after another photo is taken. This should also make it even smoother for players to take pictures, look at them, and then go back to shooting more pictures (or compare old pictures to retakes). Btw, this

functionality is also the current standard for the iOS Camera app! Let's get those "perfect shots," instead of some "good enough, too much work" shots lol.

I've attached an image of the "Backspace" button popup from the Camera app for reference.
