Currently i'm using a custom camera application, the preview looks just fines. But when i take the picture and save the devices the picture has decreased with like 80%(also size).Anyone knows why this is happening? Also in gallery the quality is poor. I am using this camera plugin
and thats the paramaters. I can't add all codes(getPicture and Save codes). You can see from the link I shared.
