For the Home Screen, they've announced a collaboration with Niagara Launcher and it appears to be close to AOSP+GServices, so I suspect that'll all work out of the box, but yeah, they really should be clearer. Also has both a NanoSim slot and eSim support powered by a not yet public Mediathek SOC.

Major concern as is often the case with new phone startups is the update policy and more importantly whether they'll be able to actually deliver over the years. Has been literally half a decade since I last used a Mediathek device, so maybe this changed, but back then they didn't have the best reputation for long term maintenance, providing drivers to enable updates, etc...
