Ever copied images from one phone to another, or from an external storage to your phone and ended up with a messed gallery?
This happens because the file modification dates of your images have now the date the images were copied at.

Here comes Image and Video Date Fixer to the rescue. It can read the creation date of images and files from its metadata and set that as file modification date.

In case your images do not contain EXIF Metadata, but contains the date in the filename itself, Image and Video Date Fixer can even parse filenames to extract the date and set it as EXIF date attribute.

The free version allows to process 100 files per batch.
If you want to process more files per batch you can buy the premium version via an in app purchase.

Attention:
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.
