Taking raw photos using Android devices I have a Samsung Galaxy S4. Is there a way in Android or an app that can take raw photos? I.e. have the raw camera data to process in a program like Photoshop. I am using Android 4.2.2.
Now it's possible to take raw photos on some Lollipop devices, like Nexus 6 and 5, among others.

Why is this possible? Because Lollipop includes a lot of new APIs to work with the camera (Camera APIs v2), so any developer today can use them and take the most of the device camera.

Nowadays, Camera FV-5 is the best app to do this (although it is compatible with older versions of Android, raw format only works on Lollipop devices). You can try it or buy it.

Note: Raw capture only works on paid version.
