Unfortunately there is nothing you can do. The only place where image names are written is database, which most likely you won’t be able to access on your old device.
It’s located in the
“/data/user/0/com.fstop.photo/files/FStop_PhotoAlbum”
You can also try this path
“storage/emulated/0/data/data/com.fstop.photo/files/FStop_PhotoAlbum”
but I think you won’t be able to access this file. If you can please copy it somewhere and let me know and we will try to find a way to recover your file names.
