I figured out how it works. App always resize to 1920px when you have only RAW file on your camera (even with option do not resize). When you have RAW + JPG or only JPG everything is ok - app transfer file with original size
The answer is from 2015, I think that app has changed since that time, because there are additional options.I don't understand how it works - there's no difference if you choose resize or don't resize, image size is the same.
