b8r2 if this really isn't nonsense then you should know we need more than an extreme and anecdotal story that you can't back up, so please share proof, if not now then when it's available to share, we'll wait but nobody's going to believe a claim like this without evidence, that's just now how it works. Obviously if GrapheneOS has a vulnerability, we'd love to know about it, but we need to know exactly what happened. Assuming you're being honest, we need to know what was used and exactly what happened for it to be patched, without an actual breakdown there's nothing the devs can do, they can't patch a ghost. We get nonsense claims like this all the time, we can't just take them at face value. You say a friend helped you with the install, if this is all true then you should consider the possibility that you friend is either a bad actor or made a major mistake that crippled the integrity of GrapheneOS.
