Reception

Positive

German Security Researcher and Pentester Kuketz said that it was the "...gold standard of Android ROMs...".

Cellularnews.com stated "GrapheneOS is arguably the best mobile operating system in terms of privacy and security."

The French Cybersecurity Agency (ANSSI) reportedly uses and suggests modifications for GrapheneOS.

Negative

Louis Rossmann, a consumer rights advocate and influencer, praised the project, but criticized the Lead Developer, Daniel Micay. A conversation between the two accused Rossmann of promoting harassment, slander, and attempted murder of Micay for commenting on the YouTube creator Techlore's video stating: "This is informative, and unfortunate." Micay subsequently threatened to ban Rossmann from their Matrix channel, and accused him of being discriminatory of people with autism.
