> This is one of multiple carrier apps in the stock Pixel OS which we don't include in GrapheneOS. We were aware of it already since we had to go through them and figure out why they exist... GrapheneOS has gone through each of the carrier apps included on Pixel generation to determine their purpose and consequences of including or excluding them. Here it is being excluded from the new adevtool project for ProtonAOSP and GrapheneOS in 2021.

GrapheneOS does massively improve privacy and security, but these apps aren't a problem if you aren't using Verizon SIM and even then the retail demo app is not remote attack surface.
