geographies. The device itself cost $399 (USD) (including free shipping in the US). Google stated that "The Android Dev Phone 1 devices are not intended for non-developer end-users. Because the device can be configured with system software not provided by or supported by Google or any other company, end-users operate these devices at their own risk."

System access and copy protection

Applications developed for distribution on Google Play allow the developer to enable copy protection which prevents the end user from copying the application from the phone. Because the Android Dev Phone allows unrestricted access to the OS, this copy protection is disabled. If the developer enables copy protection on their application, then the application does not appear on Google Play for the Dev Phone.

Availability

The device was available for purchase in 19 international markets, including United States, United Kingdom, Germany, Japan, India, Canada, France, Taiwan, Spain, Australia, Singapore, Switzerland, Netherlands, Austria, Sweden, Finland, Poland, Egypt and Hungary.
