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

'Mobile Networks' Disappeared from Settings

I have the 920F model and activated it with a UK sim a few months ago.. Have been using a US sim for the past 2 weeks, but today I went into an area with no service for a bit. Went back into an area with service and suddenly it says 'Not registered on network' when I go to make a call and 'No SIM card'.

I have gone into flight mode, cleaned and checked SIM (not a problem with the card), and then when I went to check the APN settings I noticed there was no way to get into my 'Mobile Network' settings! Its just gone!

Is it possible that it has reverted back to the European region lock and is awaiting a European SIM to be inserted before I can re-insert my US?

If it is a region lock, is there anyway to unlock it without using a European SIM as I no longer have mine and dont have quick access to one either.

Any help is appreciated. Hoping there is an easier fix.

WiFi networks disappeared forever

My device is Galaxy S6 920F

WiFi networks stop showing up after a few days of Root, Rom, or Kernel. My S6 connects to the saved ones, but I have to add the new ones manually
And I experienced it with :

*Stock Rom + Adam kernel 2.3
*Stock Rom + UniKernel v8-0002 (both Odin and TWRP)
*XtreStoLite Deo-Mod 2.3

I'm on COH2
I tried to reflash the Kernels, but it didn't work. Clean dalvik/cache didn't work as well. Factory reset/Rom will solve it temporarily.
