How can I simply change the aspect ratio of pictures on Android 4.2.2? Say from 1920x1080 to 1920x1280.
Background: On my Samsung Galaxy S4 mini, I can take pictures using the native camera app and this gives normal results. I have a remote that needs its special camera app ("Snap remote"), and the output of this app comes in the wrong aspect ratio.
I wrote the developers but they haven't replied or fixed it.
