# How to remotely scan devices?

The **Scan Device** remote action allows IT administrators to fetch real-time device details —including battery percentage, installed applications, and system configurations—to ensure the Hexnode UEM portal reflects accurate data and compliance status.
**Why is Device Scanning Essential?**
-------------------------------------

Regular scanning is the primary method for synchronizing physical device states with the management console. It updates critical metadata used for reporting and policy enforcement.

1. **Data Synchronization**: Refreshes information like battery levels, storage capacity, and app inventory.
2. **Compliance Verification**: Marks a device as compliant or non-compliant based on the gathered information.
3. **Instant Visibility**: Verifies if a device is currently reachable and active on the network.

**Scanning Devices Manually**
-----------------------------

Manual scans are used to obtain updated device details instantaneously or to confirm a device is responding to remote commands.

- #### Scan an Individual Device
    
    
    1. Log in to the Hexnode UEM portal.
    2. Navigate to **Manage > Devices**.
    3. Click on the target device name to open the summary page.
    4. Navigate to **Actions > Scanning & Monitoring** and select **Scan Device**.
    5. Check the **Action History** sub-tab to verify success.
    6. Reload the page to view updated device parameters.
- #### Scan Devices in Bulk
    
    
    1. Go to the **Manage** tab.
    2. Check the boxes for all required devices.
    3. Navigate to **Actions > Scanning & Monitoring** and select **Scan Device**.

**Scheduling Automatic Device Scans**
-------------------------------------

Hexnode UEM automatically performs an initial scan upon enrollment. Administrators can further schedule recurring scans to maintain data integrity.

1. Navigate to **Admin > General Settings**.
2. Locate the **Scheduled device scan** section.
3. Configure the **Time** settings: 
    - **Daily**: Specify the exact scan initiation time for a daily refresh.
    - **Weekly**: Select specific days of the week and the initiation time.
4. Click **Save**.

**Troubleshooting Guide**
-------------------------

#### Initiating Scan from the Device End (Force Sync)

If a remote scan fails due to communication issues between the **Hexnode UEM app** and the portal, a **Force Sync** can be initiated locally by the user.

- **Process**: Click the **Sync** button within the Hexnode UEM app on the device.
- **Function**: Re-establishes the connection to the management portal and pushes all pending actions.
- **Supported Platforms**: 
    - **iOS**
    - **Android / Android TV OS**
    - **Windows**
    - **macOS**
