I made an android Videography focused camera app that uses the Camera2 and bypasses manufacturer post-processing. Comparison video - https://youtu.be/mUlqaDxmk4k It shoots open gate 4:3 using the full sensor with manual controls. I started working on this as a personal project because I loved Lumia Camera on WP. This is being actively developed and feedback is welcome -https://chiapps.userjot.com/. You might encounter bugs, please report them.
