It's a little weird that there are very few details on this thing. Notably, one of my #1 concerns when looking for a new phone today is a good camera. And all I can find on the camera is "it's 50MP!!! " But how do actual, non-photoshopped pictures look? Does it do okay in low-light? Does it support any sort of optical zoom?
Their website is currently as slow as a frozen snail (which, if they can't run a basic web server, leads to a lot of doubt they can maintain a long-term Linux distro). So I couldn't click around much, but I didn't find anything really informative.
I tried looking at YouTube videos and only found some weird official videos of a person's hand putting the phone in a sink. Like... Yes, it has been expected for the last 8ish years that my phone will be waterproof, that's not an amazing achievement.
It also seems to be "weird" Linux, like Maemo was for the N900. I don't want weird, custom-built stuff that will be forgotten about in 12 months. Just give me a standard Debain/Fedora/Whatever and an unlocked bootloader to reinstall with what I want.
IMHO they should really look at what Valve did with the steamdeck and SteamOS, It's a custom Linux that works well, but, it's also standard hardware with an open bootloader. There are dozens of SteamOS alternatives.
