72 Product information
This Android 4.2.1 operating system is not standard Android, so access to Google Play™ is not
available. APK cannot be installed in the default location unless given permission by the
management units. Contact your BenQ dealer for the required support for management
permission. Without management permission, installing function won't work. There is no
guarantee that the self-installed APK can function normally.
