I have bought galaxy grand prime plus that has an 8 megapixel rear camera, the camera looks good put once you take a photo and see it it looks like it's blured or bad quality i showed it to a friend and he said that the sensitivity is very high, when he tried to put the camera on a surface that doesn't move at all the pictures were great. i looked for an app that fixes this problem since i found no such option to lower the sensitivity in the settings and i can't find one could you please help? the android is marshmallow
