I've been using @GrapheneOS for several months, now. I couldn't be happier. I had been using @calyxos. But, when I got a new phone I decided to try GOS. What luck! Shortly after I put #GrapheneOS on my Pixel 8 there was a staff melt down at #CalyxOS that disrupted the COS production. So I would have been stuck without upgrades. But, I have to say that I prefer the way GOS does privacy/security, anyway. And GOS support is more helpful. Go Go #GOS!!
