When copying files, Android does not retain the original creation date. This usually doesn't matter except for photos and videos as it completely messes up the gallery. Fortunately, it is usually possible to recover the creation date and thus restore the display order of the gallery. That's what this app does automatically. The free version allows you to process 50 images or videos to allow you to verify that this application meets your needs. Files can be selected individually or by folder if you don't want to fix your entire gallery. The application correctly takes into account the new PXL file format introduced by Google on its Pixel devices with Android 11. Not all versions of Android have the same possibilities or limitations. Therefore, the features offered by the application vary depending on your Android version. See notes below. For a small fee, you can purchase the full version so you can fix an unlimited number of files. Permissions The application only uses strictly necessary permissions. In particular, it must be able to read and write (for Exif data and file date) to your device's internal storage and SD card. Before Android 10 the permission used is WRITE_EXTERNAL_STORAGE and, from Android 10, MANAGE_EXTERNAL_STORAGE. This last right is mandatory to be able to modify the date of the files, otherwise the gallery does not correct itself. Important Notes: Before Android 5 (Lollipop) The application can process all types of images and videos. The MediaStore database is fixed so that images and videos display correctly in the gallery. However, the application does not touch the files and, in particular, does not modify the date of the file and does not modify the EXIF ​​data . Android 5 (Lollipop) to Android 7 (Nougat) The app can repair gallery for all types of images and videos. Here it is possible to save the date in the EXIF ​​data for certain file formats. Indeed, if Android generally knows how to read this data, on the other hand, it can only write it for JPG, PNG, DNG and WebP files. This option must be enabled in the menu as it increases processing time. Unfortunately, for these versions of Android, it is still not possible to change the date of files. Android 8 (Oreo) and 9 (Pie) Changing the date of files finally seems to work. It becomes possible for these versions to modify the date of the files! This option must be activated in the menu. Android 10 and above The MediaStore has become read-only. Therefore, it is no longer possible to update it directly. The only possibility offered by Google is to modify the date of the files and to write the EXIF ​​data in the files. Unfortunately, only JPG, PNG, DNG and WebP files support writing EXIF ​​attributes. The bad news is that the app could no longer process some videos. Fortunately, files that do not contain metadata (such as WhatsApp videos) are still corrected. For the others, we hope that forcing the MediaStore to refresh its data will reclassify the gallery correctly. Confidentiality This application is certified without tracker and does not collect any personal data.
