The Liberux Nexx smartphone will be (if it makes it to the production stage) the most powerful smartphone (with the RK3588S) to run GNU/Linux and the mainline kernel. More powerful than the PinePhone Pro, or the OnePlus 6. It will have a decent OLED display, alot of RAM, and much of what you would expect from a privacy-focused GNU/Linux smartphone such as hardware killswitches.
That is to say, this phone will (hopefully if it releases) be a true daily-driver candidate for many people, more so than the current offerings are now. While I am skeptical of it (as I am with any crowdfunded project) I think this will be a great thing if it does make it to production.

This seems to be the higher end mainline linux phone. I am getting a flx1 which is cheaper, however if i had enough I would get this as a higher end device. It would let me use it as a desktop too. And in several years we might see the newer rockchip chips in phones too, giving us enough power for most high end desktop work. I do think there is room in the market for it and remember you pay higher because you arn’t the product. You either pay for software with your data or wallet.
