Ever copied images from one phone to another, or from an external storage or cloud provider to your phone and ended up with a messed up timeline in the gallery? This happens because the file modification dates of your images will be set to the the date when you transfered your files to your phone. Here comes to the rescue. It can read the capture date of images and videos from its EXIF metadata and sets that as file modifidation date using the Android File API. In case your images do not contain EXIF Metadata, but contains the date in the filename, Image and Video Date Fixer can parse the filenames to extract the date from it and uses that to correct the file modified date. The free version allows you to fix 50 files per run. If you want to fix more files per run you can buy the premium version with an in app purchase. Due a bug in the Android Framework, fixing the file modification date will just work on Android 9 upwards. In some cases it might also work on Android 8 for some manufacturers.
