Install About this app arrowforward Rename & Organize with EXIF, formerly Picture Manager makes use of EXIF Metadata to rename and organize your pictures. This confused me for a few weeks (image appears upright when displayed in phone gallery, but then arrives on my server with bad orientation and no apparent metadata). In addition to Orientation data, you might also lose other valuable metadata such as make/model, etc. But if you have done any bitmap processing on the image and saved it to a new file, all of that Exif data is lost. Whenever the image is displayed later, the relevant image code should detect the presence of the Orientation 'tag' and rotate the image appropriately. However, other devices (especially Samsung phones in my testing), do not rotate the contents of the image file - rather, they set the Exif 'Orientation' tag. This can cause problems, especially if the device in question relies on the 'Orientation' tag to properly show the image upright.ĭifferent Android devices handle camera/image rotation in different ways - my trusty old Nexus One seems to always rotate the image immediately post capture, so the file's native contents are always 'upright' when viewed. There are no new tools or feature addition in the file manager, with the update only focusing on the UI revamp. If your Android app uses the device camera to take a picture and then resizes it (this is very, very common to reduce the size for upload), you might not realize that this resize operation strips the Exif metadata.
