Going to settings and checking out storage:

 

SD card - roughly 13 MB storage left

Internal Storage - 111 MB storage left

 

 

And my questions are:

 

What´s point with the 111 MB storage when i can´t access it?

 

And how can i access it if possible?

As with most storage mediums, you don't get the full amount listed. There are a few reasons for this:

1) the actual format of the drive takes up space (NTFS, FAT32, etc)

2) the main reason is that manufacturers usually list storage capacity as base 10, rather than base 2 (binary). Computers work in binary, so a Gigabyte is actually 1024MB, but the manufactures list a GB as 1000MB. So that's why when you start approaching multiple TB storage, you are "losing" 200+ MB.

 

Of course, it could just be a glitch.

 

Edit: A really interesting read is the use of gibibyte vs gigabyte. It's a bit misleading that OS's use the SI prefixes for decimals when referring to binary units.
