Alternatively, you can also swipe across the viewfinder to reveal the toggles. The arrow will change directions and reveal the various toggles - flash, live photos, aspect ratio, timer and filters - and you tap the button again to hide them once you're done.
To view all of the toggles, tap on the arrow that's at the top of the screen if you're holding your iPhone vertically. I personally like the clean look, but at some point, you'll surely need to make an adjustment before you take a picture.
Apple moved the settings toggles for things like the timer and filters because, well, they aren't used all that often. The next time you want to take a group photo with your iPhone and use the built-in timer, you may have a hard time finding the toggle.
