We have been looking carefully also 3.5mm jack. Personally, I’d prefer that as well (many others as well). When considering the smaller display size, our volumes and amount of customization towards PCBA (the “motherboard” of a phone), the 3.5mm jack is very likely something that we cannot fulfill. If we cannot make 3.5mm jack to happen, then we need to consider USB-C to 3.5mm jack cable for the #nextgenjollaphone.
While this is not the news most people wanted to hear I really love how open they are with their process.
