Posting from my PinePhone Pro (Mobian) - last I checked a couple months ago, it worked alright. I used the metal body hub they sell on the Pine64 website. There are a lot of issues that will probably prevent this phone from being ideal for your use case though. This phone has been both a hellish nightmare while also unquestionably being the coolest piece of tech I’ve ever used. Might get around to posting a review on c/Pine64 if I get the time.
