I picked up the 256GB model because of the price. Immediately put GrapheneOS on it, and it’s been decent. Even still works with the dock when playing music. I think GOS, or maybe Google if it’s a base issue, has some room to improve on it. There are some UI elements that don’t work on the tablet screen, such as the UI for picking the placeholder profile picture color, for example.
I simply prefer the privacy and lack of bloat vs the stock image.
