Seems that even angels need help sometimes. Since 3 months, about every two days or so my FP2 tells me that my internal storage is full (completely - 29,12/29,12 GB used). I still don’t know how this happens and which app is responsible, but what I know is that out of nowhere a folder called “Thumbnails” frequently appears in my DCIM folder. It contains low quality thumbnails from all the pictures which are on my phone (as far as I can tell), which already is stupid since I have the real pictures in eg DCIM/OpenCamera. But there are also two enormous files called “thumbnail…”, each being around 8GB. I don’t know anything about them except that it’s not actually possible for a file on the internal storage to be larger than 4GB, because of FAT32 limits.
While this was super annoying, I could just delete the folder and a couple of minutes later I have around 2-3GB free storage again (which is also weird, but that’s not my main problem at the moment).
Just now, I again was in the completely-full-situation while I tried downloading a file, and Signal was already continuously crashing because it couldn’t store incoming messages anywhere. So I deleted my Signal backup and the Tempates folder. Then Amaze started crashing all the time. I thought “well, mabe because the battery was almost empty and it couldn’t handle all this with power saving mode and I just plugged it in 2mins ago, so lets just reboot” which I did. And now, my entire storage/emulated/0 is gone. There are no folders there anymore. I thought that Amaze was just uncapable of displaying them, but also my gallery app/VLC showed nothing/shortcuts to non-existing files.
I immediately shut down my phone to prevent data from getting overwritten, but honestly, I don’t know what to do now. Every “Professional Data Recovery Pro 2018 Rescue Extreme Free Edition”-Software that I used earlier for USB-sticks etc was completely useless, and of course I don’t have a backup, because I’m always too lazy to make one.
If someone could recommend any program that could recover my files, I’d be very happy.
