Manual Camera App is the best app for Nexus Devices

Manual Camera is a great camera app that take full advantage of the new camera API introduced with Android 5.0 Lollipop. This app is a great camera app and it support only two devices the Nexus 6 and Nexus 5. This camera app comes with a very clean and easily accessible layout, with shortcuts for everything like flash, white balance, focus, ISO, shutter speed and exposure that are present on the left side. While on the right, we get gallery and settings shortcuts, a shutter button, and a dial that lets you quickly control all the settings from the left side. 

When you start the it will camera starts in auto mode, which you should have no problems shooting in, but if you want to tweak the manual focus or ISO or shutter speed, you can do that too. It also shoots in RAW, includes a few different shooting grids, and a shortcut to maximise your device’s brightness. Stock Nexus 6 Camera is very slow with auto focus and shutter speed while this app makes auto focus and shutter speed very fast. It’s a brand new app and it will improve over time.
