FastPhotoTagger

This is a GREAT app. It's the only app I found where you can add and edit metadata, such as captions or keywords. It also accepts files over 100 MB (e.g. Nikon 16 bit scans). I don't use much memory, and I can't remember it ever crashed. And, the cherry on the cake, if you have any questions they are replied too quickly.

I have 2000 scanned images of trains I took in the 70s plus 3000 digital photos taken more recently. Each has embedded exif data such as a caption, tags, gps data, date taken etc. which was loaded semi-automatically via my laptop. I have looked high and low for an app that can select photos by searching the metadata and then display each one along with its caption. To me this is a superb facility. Seeing the captions with the photos is a bit like looking through (real) photos where the taker has written a bit about it on the back. I can view my photos quickly and efficiently whenever I like and unlike many apps, this one does not bombard you with irritating ads. Having decided which Exif fields to search on I have had very few problems using the app. After set up a typical search of the 5000 images takes around 10 seconds, and the selected photos are ready to view. Note: if you are using Fast Photo Tagger with Android 6 (Marshmallow) and wish to access an SD card make sure storage access is granted by ticking the box in Settings --> Apps --> Fast photo tagger --> Permissions. I am very impressed with this app as it allows me to search and display images quickly and easily.

Doesn't work on S8+. Ace just flashes.

Attempt to open the app on my Galaxy Note 8 just gives a blinking screen. Uninstalled.

Doesn't work for me. Just flashes on the screen S8 Plus, have to force close

Couldn't write in approximate values for gps tags.

Freezes while trying to scroll in-app explorer.
