Modify Android Phone file permissions

By default, an application must not be able to read data from another application because it has insufficient permissions. But we must read, how to do?

Modify the permissions we want to read the file.

Android is Linux-based, so the way to modify permissions is roughly the same as for Linux.

Only after the handset is produced, the manufacturer restricts the access to the mobile phone and gives us a normal user, for example, we cannot delete the native app of the phone, modify the permissions of the phone file, and so on.

But we can root the phone to get the highest access to the phone.

With the highest authority, we enter the mobile phone terminal as a super user.

After entering the terminal we can modify the file permissions by chmod

Before modification

After modification

Attention:

If we can not modify the success at once, then we need to change from one folder to another, such as Modify the/data permissions, and then modify the/data/data permissions until the last we want to modify the file.
