To me the real issue is not trust in the design, but rather trust in the warranty/return/refund process. The technology is fairly new and still has potentially significant weaknesses that may leave the occasional customer with a damaged or completely broken phone through no fault of their own. To me, that is an acceptable and understandable problem and one that doesn’t inherently make the product unfit for sale to the general public. The real problem is that several manufacturers of these folding/flipping phones have warranty policies and/or practices that attempt to make the customer foot the bill for a defected product that they have not mishandled or mistreated in any way. Shane Craig has done a couple of videos on his experiences with a broken Pixel Fold and Google’s warranty service recently that highlight this practice. That is completely unacceptable and is definitely an extremely valid reason to avoid folding phones if you live in a country like the US with weak consumer laws.
