h1. Nexus S Proprietary This is the list of the proprietary libraries, binaries and firmwares shipped on the Nexus S and the status of their replacement. h2. Note on shipping libraries *Note that we don't ship any proprietary binary, library or firmware.* *First because our goal is to reach a 100% free Android distribution and also because sometimes, these are not even distributables.* h2.
