2.6 Android Security Updates

  • Security updates released through the end of July 2020 are incorporated into this release.  See the full list of updates in the appendix of these release notes.

2.7 Cloud Sync

Cloud Sync is a new application that allows customers to easily authenticate cloud storage drives like Microsoft OneDrive in order to upload tagged photos and videos captured in My Camera and browse cloud drives in My Files.

Cloud Sync provides the following features to HMT users and administrators:

  • Improving on the experience from Release 11.1, customer IT admins no longer have to find, install and deploy the OneDrive application to their RealWear devices separately. Once installed, the authentication experience for end users has been further simplified by allowing users to login with a simple code that can be easily entered in any browser on a non RealWear device.
  • After authentication, photos, which may be tagged, and videos captured from My Camera are quickly uploaded to the OneDrive cloud without needing to side load them off a RealWear device using a USB cable. The upload location can also be configured by IT admins so that a fleet of RealWear devices can upload content to a single preferred cloud location
