I have not, but there's clearly some marketing going on. That's a red flag. #GrapheneOS is not selling a product. It's literally just a Pixel phone with GOS installed. Buy an unlocked Pixel, install GOS. That's the only way. If it runs GOS, that's what it is. Everything else is a compromise at best, and a fed honeypot at worst.

I apologize for not answering your question, but it felt like the info would be relevant. I hate to see people get sucked into these "privacy phone" scams.
