Normal permissions give access to isolated
application-level functionalities. These functionalities
have little impact on system or user security and are
therefore granted without an explicit user's approval.
However, the user can review which permissions are
requested prior to application installation. An example of
a normal level permission is access to the phone's
vibration hardware. Since it is an isolated functionality,
i.e. user's privacy or other applications cannot be
compromised, it is not considered a major security risk.
