It was discussed here when it was announced. I believe it was determined the hardware is an ultra-low-budget Aliexpress design that normally retails for ~$100 that they had custom built with a mic cutoff switch added to it (probably the cause of a large portion of the hardware price increase). I dont remember the specifics, but even thr most optimistic were pretty sure it won't get hardware vendor support for even a full year based on the specific processor it contains.
Replying to myself:
Apparently I was mixing up the new Furilabs FLX1s and new Jolla phone. The FLX1s that's a major downgrade from the prior FLX1 and some people were reporting are based on a design that's really cheap on Aliexpress and using very old hardware but with a custom spin to add some physical switches to it.
The new Jolla actually does look really good compared to all the other avaiaobale Linix phone hardware options.
