How to set up Android device Restrictions?

Jump To

Setting up device and app restrictions features on the work managed devices reduces distractions and improves its security. Controlling the device settings and restricting access also prevents third-party apps from accessing corporate data and resources.

The availability of the device restrictions might differ based on the UEM plan you’ve subscribed to, the device make, and the operating system of the endpoint. Some of the features listed here are built exclusively for Samsung Knox devices, LG’s GATE (Guarded Access to Enterprise) devices, Kyocera business phones, and Android Enterprise enrolled devices.

Configuring Restrictions for Android devices

To configure Android device restrictions via the Hexnode UEM portal,

  1. From your Hexnode portal, head on to the Policies tab.
  2. Set up a new policy by clicking on the New Policy button or continue with an existing one.
  3. Navigate to Android > Restrictions > Basic/Advanced. You can set up device restrictions from there.
Notes:

  • The Advanced Restrictions in Hexnode UEM lets you have enhanced control over Samsung Knox, LG GATE, Kyocera business phones and Android Enterprise enrolled devices.
  • Restrictions set up for devices enrolled in Profile Owner mode is only applicable for the apps within the work container.

Factory Reset Protection (Google Account Verification)

Google Factory Reset Protection (FRP) is a security feature enabled by default on devices running Android v5.1+, designed to prevent the use of devices if it gets reset to factory settings without your permission. If you have a Google account set on your device and your device is reset, the device remains unusable until you log in using the Google account previously set on your device.
‘Default’ option takes the default device settings for FRP.
‘Bypass Factory Reset Protection‘ enforces the Google account verification step. Add G Suite email address and/or Google Plus Profile IDs to log in to your devices in situations where you forget/do not know the previously configured Google account credentials. Integrate your G Suite account with the Hexnode MDM server to add the accounts to the list.
‘Disable Factory Reset Protection‘ lets you skip the Google account verification step. When asked to enter the Google account credentials, the user can skip the verification by clicking SKIP.

Steps to fetch the package name of an application

To configure the following restrictions, Allow cross-profile app communication and Allow input methods, you must include the correct app package names in the restriction. If these package names are provided incorrectly, the restriction may not function as expected. There are two ways to fetch the app package name within Hexnode UEM. To fetch the correct app package names, follow the steps below in Hexnode UEM.

Method 1

  1. Navigate to the Apps tab.
  2. If the application is not yet added to the app inventory, first add the app to the app inventory.
  3. If it’s already added, search for the app for which you must specify the package name in the restriction.
  4. Ensure that the app’s platform is Android, as the same app may be available for multiple platforms.
  5. Click on the app to access detailed information about it.
  6. In the list of available details, the package name will be listed as the Identifier. Use this as the package name within the restriction.

Method 2

  1. If the application is already installed on the device, navigate to the Manage tab > Devices > Select the device to view the complete device management details.
  2. Within the device details page, navigate to the Applications tab.
  3. Now, ensure that the Identifier column is available. If the column is not present, you can add it by editing the columns available in the table.
  4. Next, search for the application and copy the identifier from the column for use in the policy.
