Google is working to introduce improved one-handed controls when using Google Photos.
in a recent APK teardown, Android Authority found a new floating toolbar that appeared in albums. This new tollbar appears closer to the bottom of the screen and even includes a new button to help organize the albums you've uploaded photos to. This toolbar appears at the bottom of the screen and disappears as you scroll but it is easy to bring back simply by scrolling up. The bar never changes location, so it's much easier to access the share and add buttons with one hand.
