I've heard, which would be mega awesome when it does come out. Maybe I wouldn't have to fight RCS so hard lol. Unfortunately this Pixel 8a I used is only a year old, so getting a new phone in 1-2 years seems like a waste. But if Google goes nuclear in a few years, it's either Graphene hardware, Linux phone, or dummy...
I refuse to go back to Apple, and I didn't come to GrapheneOS just to go back to stock Android.
