I cannot take pictures because my phone says "your internal storage is running out of space" I have over 7GB of internal space left on my phone yet it keeps telling me to delete files and pictures. I deleted all of my pictures and some big apps but it continues to tell me the same thing when I try to take pictures. I have a droid RAZR mini. It has no space to put a SD card in. Unless I can somehow take off the back. Someone help please.
I managed to fix the issue where I was getting an "Insufficient storage" for my camera app.  This was after I 'changed' a MicroSD card in my Moto X Pure.  It was driving me a bit batty.  But it's fixed.

I downloaded a file explorer (in my case it was ASUS File Manager).  I saw that I had a DCIM folder.  (Under Internal Storage and navigate to DCIM).  I found that I was unable to move any files to this folder or even SEE the folder on my laptop (as you can connect to your phone using the ASUS File Manager via a wireless mirroring connection).  So I tried to create a DCIM folder via my laptop.  But got a permission denied.  So I went back to the phone's file manager and renamed the DCIM folder to DCIMold.  I then created another DCIM folder.  Yay!  That seemed to work.  And more excitingly so did my camera app.

So it was the dreaded lack of a DCIM folder.  In my case it wasn't because it was missing but rather that it was somehow corrupted and had the wrong permissions.  If it was even really there.

If anyone needs a better explanation let me know.  I just jotted this down for my reference as I was so excited to get over the latest hurdle on the phone!
