Of course, when it comes to the soak tests, those participating must abide by Motorola's rules which means confidentiality is key. Having said that, the update could relate to the recent camera update for the Motorola Moto X, and if there is one thing that DROID owners both big and small like to see for their handset, it is improvements to the snapper. Owners of the updated devices should notice improved color accuracy and focus speed among other changes.
To participate in the soak tests, you have to be a member of the Motorola Feedback Network. The tests are designed to allow a small number of Motorola device owners to receive an update in advance of a wider rollout. This way, if there are any problems with the update, it is contained to a small number of devices.
