Other Unintended Access
- Users might gain access to Airplane mode, Wi-Fi, Bluetooth and other device settings via the Quick Settings panel in the Notification drop-down even if Settings app is disabled by EHS. This can be prevented with settings configurable using the UI Manager through StageNow or EMDK.
- Wireless capabilities also can be individually disabled through these MX modules:
- SettingsMgr for Airplane Mode and Wi-Fi
- UiMgr for Quick Settings and the "Gear" icon
- WirelessMgr for Bluetooth, GPS, NFC and WWAN
- MX modules are accessible using EMDK or StageNow tools.
- Taking a screenshot (by pressing the "volume-down" and "Power" buttons simultaneously) while in User Mode might expose users to the Gallery app or to apps used for sharing images such as Gmail and MMS. To prevent this, disable such unwanted apps in the Disable/Enable Applications section of Optional Feature Tags section.
- If the Programmable Keys feature on the Android System Settings panel is used to program a key to launch an application, that key mapping will be available in User Mode.
