It's not a duplicate, because this question isn't about shredding files that already deleted, it's about deleting them in the first place in a way that recovery software wouldn't find it.

I delete photos, but this software FindMyPhoto still recovers them. I think photos are really deleted, and those that restored are thumbnails, because when I restore them they doesn't look that sharp. I delete photos through the Gallery application. I tried to clean Gallery app cache, that doesn't help.

I tried to use firmware (preinstalled by manufacturer) that cleans Android of junk (like cache etc), but the application above still finds it. And I don't know how to completely remove the files. It's like I've got a device with undeletable files and starting really hate Android (it's really betrayal and annoying behavior).

So if you could recommend some application may be (preferably from a well known company or free software, like those from F-Droid repository) I would appreciate it. Thanks.

  • it is still a mystery to me, this app does not restore anything on my device (rooted, no encryption). if you delete a file via rm from terminal and clear gallery app data, the file is gone

    You could take a look at my corresponding app list. Though due to wear-leveling on flash storage, I always wonder if those apps even can work.

    Thumbnails are separate files from the actual pictures on many phones. They are usually hidden from many apps because they are located in a directory (or subdirectory of one) that also contain a hidden file named .nomedia

    Well stop using the gallery to delete what the gallery tells you isn't there... Use a REAL file manager to delete images and thumbnails and then go clear the gallery app cache in Android settings->Apps->"Gallery app name"->Storage... Then use the "clear cache" button...

MIUI Gallery creates thumbnails in

/storage/emulated/0/Android/data/com.miui.gallery/files/gallery_disk_cache/full_size
/storage/emulated/0/Android/data/com.miui.gallery/files/gallery_disk_cache/small_size

Some versions of MIUI Gallery do not even delete thumbnails when pictures are deleted.

Unlike for user apps MIUI does not provide the Clear Data button for system apps. The Clear Cache button does not wipe app data, therefore one need 3rd Party app to Clear Data (Link2SD can do it)

Once you deleted files from

/storage/emulated/0/Android

such apps like FindMyPhoto and similar stop working, as they don't really undelete files.
