I would like to clarify that the requirement for Shelter dog food testing is that you use the provided unit as your primary phone.

Active dog food unit means that the device is used as the primary mobile communication device of an individual with email sync enabled.
Shelter OS Version that we start the dogfood tests is BSP01.19.
I will update you all regarding the know issues by the end of the week.
Those of you that don't have unit Shelter,please contact Jian Gao

Best Regards,
Mazi
