Are there maybe reasons for it? Sure, licensing expensive but pointless Gorrilla glass and other such non-sense does rise the price
I think the biggest reason is more powerful hardware. More expensive glass sure contributes to the price, but I don’t think it’s much.
but it doesn’t change the fact that the PPP is vastly overpriced, while the PP was originally not (these days it is, but that’s just because it still has the same price as half a decade ago).
Braveheart edition was released in 2020. In this year you could buy Xiaomi Redmi Note 8 for $140.00. It’s so much better deal the PinePhone. GNU/Linux phones are always overpriced due to the reasons I mentioned above.
