Known issues and limitations

Setup

Scheduled tasks

By default, there are scheduled tasks that stop (at 4:00 am) and restart (at 4:05 am) the Sophos Mobile server. If you want to update Sophos Mobile during that period, disable these tasks before the update and re-enable them after the update is finished.

Changing the server URL after installation

After changing the server URL using the Configuration Wizard you need to reactivate the Sophos Mobile standard license. To do this, go to Setup > System setup > License, enter your standard license key in the input field and then click Activate.

Android devices

Knox container can’t be created on Android 5.0 devices

You can only create Knox containers on devices with Android 5.0.1 or later. Existing containers on Android 5.0 devices are not affected. This is a restriction of the Samsung Knox SDK version Sophos Mobile 9 uses.

Some Samsung Knox devices must be restarted to turn on Kiosk Mode

You must restart Samsung devices with Knox Standard (formerly called SAFE) SDK version earlier than 5.4 after installing a Kiosk Mode profile. If you don’t, the user could stop all running apps in the task manager and switch to the default launcher home screen.

Preventing additional device administrators on Samsung Knox devices

The Knox premium restriction Prevent installation of another administrator app on a device is ignored if there’s already another device administrator activated. Make sure Sophos Mobile Control is the only device administrator before you assign the restriction.

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’s 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. These apps can’t be controlled or protected by the Sophos Mobile Control app or by App Protection.

Password reset removed for “Device administrator” devices with Android 7 and later

You can’t reset the password for devices running Android 7 or later. This applies to devices where Sophos Mobile is the device administrator. This is because Google removed the “Password reset” command from their device administrator API. Android enterprise devices, devices on which Sophos Mobile is device owner or work profile owner, are not affected.

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 with the profile even if the policy is removed. You can send a policy containing another Email configuration to the device. The latest Email configuration is always used. However, it is not possible to remove the configuration from the work profile. If the configured account is removed, you must remove the whole Android work profile 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. It is a permission setting for apps that are able to install other apps. For example a file manager app. It isn’t possible for Sophos Mobile to check if any third-party app has this permission. The Apps from unknown sources compliance rule is ignored for devices running Android 8.

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 isn’t 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 enables the internal WebView app. However, you might 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 more information regarding this issue, see the Google article https://support.google.com/work/android/answer/7506908 (external link).

Android enterprise: On some devices, Factory Reset Protection (FRP) can’t be turned on

On some devices capable of Factory Reset Protection (FRP), we have noticed an “FRP is not supported error” when FRP is turned on using Sophos Mobile. This issue isn’t caused by Sophos Mobile.

Android enterprise: Device owner enrollment sometimes fails on unencrypted devices

Normally when you enroll an unencrypted device in Android enterprise device owner mode, the device is initially encrypted and then enrolled. On some devices (including Samsung devices using Android 6.x or earlier) the process stops after the encryption and the device remains unenrolled.

As a workaround, restart the enrollment after the device was encrypted.

Android enterprise: Enrollment through Sophos NFC Provisioning app sometimes fails for Chinese

On some devices (e.g. seen on a Samsung Galaxy A3) enrollment in Android enterprise device owner mode fails when the language of the Sophos NFC Provisioning app is set to Chinese.

As a workaround, use a different language.

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 doesn’t work reliably

In some cases the silent trigger sent by the Sophos Mobile server doesn’t result in an automatic background synchronization. The user can synchronize the app manually.

Managed Sophos Secure Workspace loses the management status after upgrade of app

This is a rare issue. Sophos Secure Workspace becomes unmanaged after upgrading. This is caused by a problem with 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 resolves the problem.

Single App Mode profile changes do not affect the device

Updating an iOS Single App Mode profile doesn’t update all contained settings. The Disable… options are updated correctly. All other options only work on the first installation of the profile. To change these settings you need to remove and reinstall the profile. This is an issue in Apple iOS.

Restricting app removal doesn’t work reliably

On some devices, users are able to uninstall apps even if the Allow app removal restriction is disabled in the iOS device profile. This is an issue in Apple iOS.

iOS email synchronization is broken with the internal EAS proxy

After upgrading your Sophos Mobile installation to version 9.0.2, the iOS email app fails to synchronize with your email server if you use the internal EAS proxy. It appears that this issue is caused by the switch from the HTTP/1 to the HTTP/2 protocol. For further information and a possible workaround, see Sophos knowledge base article 133752.

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. 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 earlier than GDR1 do not set Exchange account names correctly

Windows Phone devices running 8.1 versions earlier than GDR1 don’t 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 doesn’t work correctly for Windows Phone and Windows 10 Mobile devices if no passcode policy is enforced by Sophos Mobile. The devices don’t 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 doesn’t work correctly for Windows Phone and Windows 10 Mobile devices if encryption isn’t enforced by an Sophos Mobile Restrictions policy. The devices don’t 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 isn’t 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 doesn’t 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.

Sophos Mobile Admin console

Pages layout corrupted after Sophos Mobile update

Some pages of Sophos Mobile Admin might look corrupted after you’ve updated your installation of Sophos Mobile. To correct this, clear your browser cache and reload the page.

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 isn’t necessary (this only applies to Microsoft Active Directory). It’s also not necessary if the device's Active Sync ID is already known. That is the case when using Sophos Secure Email or Samsung Knox.

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 with Apple DEP profiles configured fails. To delete those customers, you need to delete the Apple DEP profiles before deleting the customer.

Task bundle tasks for profile removal don’t list the current profile names in some cases

When profiles are renamed, removal tasks may 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. You should check the list of installed certificates in the device details.

Empty Windows Mobile policies are not correctly listed in the installed policy details

Assigning empty policies to a Windows Mobile device doesn’t 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 doesn’t work with all apps

The restriction for Copy & Paste on Windows 10 Mobile doesn’t work for some apps. Those apps still allow Copy & Paste actions.

Detecting deactivated Defender on Windows 10 computers doesn’t work in some cases

In some cases, Windows 10 computers 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 doesn’t check if real-time protection is enabled.

Removing duplicated Android profiles using a task bundle doesn’t 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 don’t register correctly for push notifications

Some Windows 10 mobile devices and computers don’t 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 a known 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’s 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. As a workaround, use a different browser to configure the external directory connection or the SMTP settings.

Number of users invited to Apple VPP at the same time is limited

When you invite too many users to the Apple Volume Purchase Program (VPP) at once, Apple might reject further requests for a few minutes. If you are experiencing this issue, please reduce the number of users included in the invitation.

This issue will be fixed in a future version of Sophos Mobile.

Android zero-touch enrollment and Samsung Knox Mobile Enrollment not possible with self-signed certificate

If you use a self-signed SSL/TLS certificate for your Sophos Mobile sever, you can’t use Android zero-touch enrollment or Samsung Knox Mobile Enrollment. We suggest you use a certificate issued by a globally trusted certificate authority (CA) instead.

Not possible to save HTML-formatted text

In some cases, you get an error “Text contains forbidden HTML elements” when you try to save SSP enrollment texts or system messages that contain HTML formatting, although the text you’ve entered is valid. This issue is caused by an error in the HTML parser library.

As a workaround, change the font size of underlined text and delete any “style” attributes.
