I was in a training course recently run by 20 year veteran of Gov cyber security (not US).
When I asked him about GrapheneOS he said it was a good option and much better than vendor android or iOS, but that he uses Chinese phones (Huawei & Honor) for his personal devices exclusively these days.
Sounds like he had a pretty high turnover though and is obviously well aware of what information is shared/leaked and I imagine his devices are as locked down as they can be.
Surprised me though.
