Both the Windows Camera and Microsoft Photos apps for Windows 10 Mobile and desktop received updates today, and are currently being rolled out to users through the Windows Store.
The changelogs for both apps aren"t included with the updates, but what we do know is that the Photos app - now at version 15.820.15120 - on Mobile now has pivot (swipe left or right) controls to access Albums and Photos, versus the old version"s "Hamburger" menu, the latter of which has become a common feature in both the desktop and mobile versions of Windows 10.
Not much is known about the Windows Camera update - now at version 5.49.2004 - due to the lack of release notes, but you can grab the updates at the links below, or wait for Windows Store to do the update for you.
