How does storage space in our phone is partitioned? How can we access our storage space?
Most Android phones have
eMMC (flash memory), partitioned in GUID partition table (
GPT) just like a PC's hard disk. There are usually less or more 50 partitions on a latest Android phone. OS uses
/system while user uses
/data mainly. Internal SD card is
/data/media. Other partitions are smaller.

If you have a rooted phone, you can use Linux tools (
gdisk etc.) to manipulate Android 's partition table. But that's really risky.
To fully access storage space, you need root permissions.
