Security

RealWear continually enhances the security of its devices through updates in each firmware release.

The most visible is via periodic security patch updates for the Android operating system. Each month’s Android patch set is closely analyzed by RealWear and incorporated into the code base as appropriate. (Not all patches are included as they are not relevant. For example, some patches are for different chipsets than what is used in the HMT-1 or are for mobile phones only.)

Android security patches from February 1 – April 30, 2021 have been integrated into the RealWear device firmware.

Bug Fixes

The specific bugs that have been fixed will be provided in the release notes when available. The fixes are not only to the operating system, but also to the RealWear native applications that are shipped with the operating system. Several have been incorporated directly, in response to issues discovered by the ISV partner community.
