The newer Google Camera APK has a redesigned UI that placed the camera modes below the shutter button and hid the settings for each camera mode, requiring you to swipe down from up top to show them. This leaked APK was notably a “dogfood” build, ie. an internal release intended for only Googlers to test, so it wasn’t meant to be used by the public.
The biggest change in this new release is obviously the new UI, but we’ve already gone over this change in-depth in a previous article. Apart from the new UI, I did notice that the new app version has renamed “camera coaching” as “framing hints” and has added the new “social share” feature. Basically this feature lets you quickly share a photo to a social/messaging app of your choice. All you have to do is swipe up on the preview of the picture you recently took and then select one of the apps from the options that appear (up to 3 of your choice.)
The framing hints simply help you take better photos by making recommendations when you aren’t holding your phone properly.
