16g内存只显示12g可用(16g内存只有13.9g可用)

Manufacturers calculate the memory of computer mobile phones according to 1G=1000M, but the actual computer calculation is 1G=1024M, so the maximum memory of 16G is only more than 15G Or less!
The 16G memory only has 12G available space. That’s because there are system files and hidden files occupying part of the space. This is normal!

Normal. In fact, after 16G is formatted, it only has about 14.9GByte. It is divided into several partitions and hung in different directories. The total is about 14.9GByte, which is equal. It seems that Sanshuang has not killed you. ! It can also be seen here that the system occupies about 2.2G of space. This space cannot be used by us - even if it is empty - not only because it is generally invisible and read-only, but also because it is not related to the so-called "built-in memory card". "It's not in the same zone at all!
Of the remaining space, part is still occupied by the Dalvik virtual machine, and the actual allocated space for the so-called "built-in memory card" is less than 12G!
