I have a Samsung A8 with 32GB of internal storage and 32GB of SD. I recently connected it to my PC through USB, and ran a PC disk space analyser on it. Everything on the SD card looks normal and understandable, but the internal storage is weird.
Okay, so the internal file system shows only the storage is only 24.1GB instead of 32GB, I guess that's typical for the games that storage manufacturers play with their sizing practices, I don't care about being shortchanged a little. But it shows that 22.8GB of the 24.1GB is used up. I then fired up the disk space analyser program, and it showed that I'm only using 231MB of space on the internal storage: 104.7 MB for Android, 94.5 for WhatsApp, and 19.0 for logs. The rest are just sub-megabyte numbers. So where is the rest of the system hiding? The remaining over 22GB of stuff?
