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.

WARNING: This is a Kickstarter device still, and needed funding to even create a proof of concept device last time it was discussed (extensively). It's a Flagship phone device and price, but with only the oldest of pans on how it's actually going to deliver some on of the promises.
