Sophos Mobile Encryption Version 2.0 for Android Release Notes

New in this release

Support of Skydrive as cloud storage provider

Sophos Mobile Encryption now supports SkyDrive (https://skydrive.live.com/) as cloud storage provider. 

System Requirements

Sophos Mobile Security runs on Android devices with an Android version 2.3.3 (API level 10) and higher.

Note: With the release of 2.0 Android devices running on Android versions prior 2.3.3 will not be supported any more.

Installation

Installation of the application must be done via Google Play.

Known Issues

Encrypted Files cannot be opened by third-party applications 

Encrypted files cannot be opened by some third-party applications due to problems with access permissions. For displaying the content of an encrypted file, the file needs to be decrypted beforehand and access permissions are applied to the file so that only this single file can be opened by the third-party application. Some third-party applications fail to work properly if they're not granted universal access to files and therefore cannot display the file.  Applications known to have this problem are ASTRO Image Viewer or ES Image Browser. If this problem occurs, please use another application to view the decrypted file.

Going back when linking a Google Drive account may cause Google Play Services to crash

When the user links a Google Drive account in Sophos Mobile Encryption, the application triggers the selection of an account in a Google application. Selecting "Add Account" on the first screen directs to the "Add a Google Account" screen. If the user then clicks the back button, the Google Play Services may crash (seen on a Nexus 7, with Android 4.2.1). This crash is caused by another Android application and not by Sophos Mobile Encryption.

Viewing of favorites may show an outdated version of the file, e.g. using the Android Gallery App

Some applications used for viewing favorites of Sophos Mobile Encryption do cache files internally and do not recognize when only the file content changes. E.g. the Android Gallery application caches all pictures it views. When only the content of the file changes, the Android Gallery App does not recognize the change when opened from Sophos Mobile Encryption and displays the cached content. Only a change of the file name will cause the Gallery App to reload the file. Please use another application that does not show this behavior for viewing the favorite files or forcibly close the Gallery App before viewing updated content.

Update from Version 1.0 may result in unlinking of DropBox and missing metadata for the favorites

Updating from version 1.0 may unlink an already linked DropBox account. Please link the account again and all favorites of the DropBox will be visible again. It may also happen that the file metadata of favorites (size and sync date) cannot be retrieved and only default values are shown. After syncing the favorites again all metadata is restored. The favorites can still be opened, even with wrongly displayed metadata.

Microsoft Skydrive not working on certain devices

The Live SDK for Android version (5.0) that is used for Sophos Mobile Encryption to support Skydrive as storage provider is distributed by Microsoft as pre-release, time-sensitive unsupported software that may not operate correctly. Therefore it may happen that Skydrive is not working on certain devices, e.g. we could not logon on to Skydrive on a Motorola Defy+ with Android 2.3.4. 

Developer Option Don't Keep Activities causing problems when user-visible interaction is required with third party applications

Sophos Mobile Encryption relies on third party applications to support the different cloud storage providers. When requiring user-visible interaction with such third party applications (e.g. to logon to a cloud storage provider like Google Drive), having the developer option Don't Keep Activities activated may affect the normal lifecycle of SMEnc or even cause the crash of it . This is caused by the OS behavior activated with the Don't Keep Activities setting: SMEnc may be closed while a third party App is shown, whereas the third party application tries to start SMEnc resulting in an infinite loop. As recommended by Google, this Developer setting should not be activated in normal use of a device.
