I have read my reviews of other users. Also I have a 5-inch display phone from Sony, but I have not said problems. I find the app even very good, because there are many editing options. For me, everything worked perfectly first time. A tip: Anyone who has completed an image editing and wants to edit a new image, with the camera, the press must return to the image shooting, so he can edit the current photo, first of all because the previous image is shown.
