Photos/Videos Disappeared after shutdown

I've notice that sometimes my photos/vídeos disappear from my cellphone.
At first I noticed with media received from whatssapp and I thout it was an app issue and don't give to much attention to it.
Now I realized that recent media disappear, and then paying more attention I notice that they disappear just after my cellphone suddenly shutdown when running low battery.

Today I had a sad story, I was recording a trial, after that while using Waze my phone just shutdown without showing the logo information "shutting down". When I charged my phone and tryed to send the videos to people in the trial they do not appear. Searching for them I discovered the files still there, but the size now is 0 kB (and I watched some of them before the sudden shutdown)

So the question is, does anyone is facing the same issue? Is there a known solution? And the most important to me, does anyone know how to recover the videos?

Since Android does not appear anymore as a common removable card I can not use anymore tools like "miniTool Power Data Recovery".

Can anyone help me?

Thanks
