Android partition layout
Android has multiple partitions such as /data /system /cache. Usually apps are installed in the data partition. For rock pro, we have 8GB on board storage, for rock2 square model A, we have 16GB on board storage, for model B, it's 32GB. Some users install a lot of apps on the device so they might want to make the /data partition as big as possible. This guide is how to change the size of each partition.
