Known issues and limitations


Scheduled tasks
If you are planning to run the update to Sophos Mobile 8 overnight please disable the scheduled tasks to stop and restart the Sophos Mobile server (default: 4:00 am and 4:05 am) if those times interfere with the update and migration procedure. You can re-enable them after the update is finished.
Changing the server URL after installation
After changing the URL of the server using the Configuration Wizard, the Sophos Mobile standard license needs to be reactivated. To do so, go to Setup > System setup > License, enter your standard license key in the input field and then click Activate.

Android devices

On some Samsung Knox devices it is not possible to add a profile with a root certificate
On some Samsung Knox devices (e.g. seen on a Samsung Galaxy S2 with Android 4.0.3), installing a root certificate via a profile does not work. This is an issue of the Samsung API where a call to a Samsung API returns success although the root certificate could not be installed on the device.
On some Samsung Knox devices it is not possible to remove the VPN profile from the device
On some Samsung Knox devices (e.g. seen on a Samsung Galaxy S2 with Android 4.0.3), removing a VPN profile in the Sophos Mobile admin console does not work. This is an issue on the Samsung API on the device where removing the profile via a call to the Samsung API succeeds although the VPN profile is actually not removed on the device.
Some Samsung Knox devices must be restarted to turn on Kiosk Mode
Samsung devices with Knox Standard (formerly called SAFE) SDK version < 5.4 must be manually restarted after a Kiosk Mode profile was installed. Otherwise, the user would be able to stop all running apps in the task manager and then switch to the default launcher home screen.
Knox premium restriction "Prevent installation of another administrator app" can only be applied on the device when there is no other device administrator app active
The Knox premium restriction Prevent installation of another administrator app can only be applied on a device, when there is no other device administrator app activated. If another device administrator app is already activated, e.g. the Android Device Manager, the user has to first manually disable the device administrator for this app so that the policy can be applied (see also This policy can only be applied if there are no other administrators activated in the Samsung Knox documentation).
Android 6 power saving features might impact Baidu push notifications
The App doze and Stand-by mode power saving features introduced with Android 6 can impact the receiving of Baidu push notifications.
On Sony devices it is not possible to protect or control so called small apps (with an app protection or app control profile)
Small apps are Sony specific apps on Sony devices that overlay existing apps. Due to the technology of these type of apps, they can’t be controlled or protected by the Sophos Mobile Control app or by App Protection.
Password reset on Android 7.x device was removed
With the release of Android 7.0, Google removed the methods for resetting device passwords.
Email accounts can't be removed from the Android work profile (only if you remove the complete profile)
If an Exchange email account is transferred to an Android work profile, the account stays on the profile even if the policy gets removed. It is possible to send another policy containing another Email configuration to the device. Always the last Email configuration gets used. However, it is not possible to remove the configuration from the work profile. In case the configured account should get removed, the whole Android work profile must be removed from the device.
No compliance violation “Installation from unknown sources” on Android 8
Starting with Android 8, the installation of apps from unknown sources is not a device setting anymore. Instead, it is a permission setting of apps that are able to install other apps - like for example a file manager app. Currently, it is not possible for Sophos Mobile to check if any third party app has this permission. Therefore, the Apps from unknown sources compliance rule is ignored for devices with Android 8.
Android enterprise: No manual enrollment for “Managed Google Play Account” scenario
If Android Enterprise is set up using the "Managed Google Play Account" scenario, devices can only be enrolled by scanning the QR code or by using the Configure app link from the enrollment email.
Android enterprise: Chrome app enabled in work profiles by default

There is a known Android issue related to the work profile. Starting with Android 8, the Android internal WebView app is no longer enabled by default. As a result, apps in the work profile that rely on the WebView app may stop working. Google resolved this issue by enabling the Chrome app, which in turn enables the internal WebView app. However, you may not want to allow a browser app in the work profile. As a work around, use the App Control configuration of your Sophos Mobile Android enterprise policy to block the Chrome app.

For information from Google regarding this issue, see https://support.google.com/work/android/answer/7506908.

iOS devices

When use of Safari (iOS Browser) is restricted via a profile, recommended and required apps can’t be installed via an iTunes link
Installing a recommended or required app via an iTunes link on an iOS device requires the use of Safari. If the use of Safari is restricted, recommended and required apps can’t be installed via an iTunes link.
Automatic synchronization of the Sophos Mobile Control app against the server does not work reliably
In some cases the silent trigger sent by the Sophos Mobile server does not result in an automatic background synchronization. In those cases the user can still synchronize the app manually.
Managed Sophos Secure Workspace looses the management status after upgrade of app
When upgrading a Sophos Secure Workspace for iOS app that is already managed by Sophos Mobile, it may happen in very rare cases that Sophos Secure Workspace is no more managed on the device. This is caused by an undefined behavior of the Apple iOS mechanism used for managing the app: the managed settings are lost. Installing the profile again for the device in the Sophos Mobile admin console takes the app under management again.
Single App Mode profile changes do not affect the device
Updating an iOS Single App Mode profile does not update all contained settings. The Disable… options are updated correctly. All other options only work on the first installation of the profile. For switching those settings, the profile must be removed and installed again. This is an issue in Apple iOS.
Restricting app removal does not work reliably
On some devices, users are able to remove apps even if the Allow app removal restriction is disabled in the iOS device profile. This is an issue in Apple iOS.

macOS devices

Network Access Control (NAC) not possible for Macs connected via Ethernet
Sophos Mobile can only retrieve the MAC address of a Mac’s Wi-Fi network adapter, not that of its Ethernet adapter. Because for Network Access Control (NAC) devices are identified by their MAC address, a Mac connected to the network via its Ethernet adapter is treated as an unknown device when your external NAC software asks Sophos Mobile for the device’s network status.

Windows Mobile devices

Windows Phone 8.1 devices < GDR1 do not set Exchange account names correctly
Windows Phone devices running 8.1 < GDR1 do not use the Exchange account display name as configured. Instead, they just use a numbering scheme. This display issue does not affect the actual synchronization. Newer Windows Phone 8.1 versions use the name as configured.
A "no passcode" compliance violation is reported although a passcode is set on the device
The Password required compliance rule does not work correctly for Windows Phone and Windows 10 Mobile devices if no passcode policy is enforced by Sophos Mobile. The devices do not report a passcode being set if the user does this without being forced to by a policy. This is an issue in Windows Phone and Windows 10 Mobile.
A "no encryption" compliance violation is reported although the device is encrypted
The Encryption required compliance rule does not work correctly for Windows Phone and Windows 10 Mobile devices if encryption is not enforced by an Sophos Mobile Restrictions policy. The devices do not report a device to be encrypted if the user does this without being forced to by a policy. This is an issue in Windows Phone and Windows 10 Mobile.
SafeSearch restriction
The Windows Phone 8.1 restriction SafeSearch permission is not working correctly. Due to an issue in Windows Phone 8.1, the restriction is ignored on the device and defaults to “moderate”.
Windows 10 Mobile devices can’t be checked for compliance rule "Data roaming allowed"
On devices that run Windows 10 Mobile, Sophos Mobile can’t check for compliance with the Data roaming allowed rule because the operating system does not provide the Sophos Mobile Control app with the relevant information. When you forbid data roaming, a Windows 10 Mobile device with data roaming enabled is still reported as compliant.
Windows Phone 8.1 devices ignore email configuration changes
In some cases, Windows Phone 8.1 devices ignore changes that you make to the IMAP/POP configuration of a Windows Mobile policy. To get around this issue, change the email configuration in two steps: First remove the IMAP/POP configuration from the profile, then make the required changes to the configuration and add it again.

The IMAP/POP configuration for Windows Mobile policies is a new feature introduced with Sophos Mobile 7.1.

Sophos Mobile Admin console

Synchronizing an Android device with an Exchange server
Android devices are automatically enabled through the EAS proxy, if the device was enrolled through the Self Service Portal. If an administrator has added the device to Sophos Mobile, it is required to enter the sAMAccountName value in the respective property of the device details view to make ActiveSync synchronization possible. If devices are registered with an LDAP entry and SSP, this is not necessary (this only applies to Microsoft Active Directory). It also is not necessary if the device's Active Sync ID is already known. That is the case when using Sophos Secure Email or Samsung Knox.
Password fields may look corrupted in Internet Explorer 10
When entering a password, e.g. in an Exchange email configuration, it may happen that the password is cut off and not all asterisks are shown. The user can still enter any password, although the input field does not show the correct amount of characters entered. This is caused by a defect in the web control within the standard framework used by Sophos Mobile.
Admin console may look corrupted in Internet Explorer
Internet Explorer may classify the Sophos Mobile admin console as an intranet site. As a result, compatibility mode is activated by default which results in a corrupted view and erroneous behavior. To turn off this browser feature, clear the Display intranet sites in Compatibility View check box in the Compatibility View settings of Internet Explorer.
Plain Exchange ActiveSync traffic is no longer supported using the internal EAS proxy
Exchange ActiveSync traffic without encryption (SSL/TLS) is no longer supported by the internal EAS proxy.
Customers having Apple Device Enrollment Program can’t be deleted
The deletion of customers having Apple DEP profiles configured fails. To delete those customers, the Apple DEP profiles need to be deleted manually before deleting the customer.
Task bundle tasks for profile removal do not list the current profile names in some cases
When profiles are installed on devices and then later are renamed the list for profile, removal tasks in task bundles might be confusing. Tasks might display the profile with the old name.
List of Windows Mobile root certificates may not reflect the actual state
Installing root certificates as part of policies is always reported as successful. The actual list of installed certificates can be checked in the device details.
Empty Windows Mobile policies are not correctly listed in the installed policy details
Assigning empty policies without any settings to a Windows Mobile device does not correctly update the installed policy details displayed in the web console. Instead, settings of previously applied policies might be shown.
Restricting Copy & Paste on Windows 10 Mobile does not work with all apps
The restriction for Copy & Paste on Windows 10 Mobile does not work for some apps. Those apps still allow Copy & Paste actions.
Detecting deactivated Defender on Windows 10 Desktop does not work in some cases
In some cases, Windows 10 Desktop devices might be reported as compliant even if Windows Defender is disabled. This is because the compliance rule Defender activated can only check if the Defender service is running. It does not check if realtime protection is enabled.
Removing duplicated Android profiles using a task bundle does not work
An Android profile that has been created by using the Duplicate command in an older version of Sophos Mobile can't be removed from devices using a task bundle.
Some Windows 10 devices do not register correctly for push notifications
Some Windows 10 Mobile and Windows 10 Desktop devices do not register correctly for the Windows Notification Service (WNS). There is a time out of their push registration after 30 days, and the devices fail to renew the registration automatically. Although the Sophos Mobile server enforces the renewal, some devices send the old, invalid push registration information to the Sophos Mobile server when they re-register. As a result, the Sophos Mobile server can't send push notifications to these devices to synchronize the built-in MDM agent. This is an issue in Windows 10.
Accurate server time required to set up Android enterprise

If the system time of your Sophos Mobile server deviates by more than 15 minutes from accurate time, you will not be able to set up Android enterprise for your organization using the Managed Google Play Account scenario. This is because the Sophos service that manages Android enterprise communication classifies the request from your Sophos Mobile server as malicious and rejects it.

Configuring the external directory connection not possible because of Chrome issue (field content disappears)
When configuring the external directory connection, Google Chrome automatically tries to fill in a saved user account. The field content is automatically removed and added again, and it is not possible to configure the user credentials. Also, when configuring the SMTP tab for the super administrator, saved credentials are automatically inserted.

This issue is caused by a defect in Google Chrome 59. Because of that, the issue can’t be solved by Sophos Mobile. As a workaround, use a different browser to configure the external directory connection or the SMTP settings.

Standalone EAS proxy: PowerShell mode not supported for Exchange Server 2010
For email access control through PowerShell, the standalone EAS proxy doesn’t support Exchange Server 2010 email servers. If you’re using Exchange Server 2010 with Sophos Mobile 7.1 and don’t want to update your Exchange Server version, we recommend you continue to use your existing installation of the standalone EAS proxy. The EAS proxy from Sophos Mobile 7.1 also supports Sophos Mobile 8.

Self Service Portal

Self Service Portal enrollment of Windows computers is disabled after update to Sophos Mobile 8

If you’ve configured Self Service Portal enrollment for Windows computers, you must adjust the configuration after you’ve updated Sophos Mobile to version 8. In Sophos Mobile 7.1, the initial package is a policy while in Sophos Mobile 8 it is a task bundle.

For information how to re-enable Self Service Portal enrollment for Windows computers, see the Sophos Mobile installation guide, section Post-update tasks.
