The YotaPhone 2, a Russian-made smartphone with an LCD front and an e-ink back, launched for US buyers via the crowdfunding website Indiegogo. That crowdfunding campaign proved successful, and by all accounts the oddball two-faced smartphone would eventually be making its way into backers’ hands. Only, it won’t be, at least not in the way backers expected. The company started sending emails to Indiegogo backers today advising them that the planned US release has been cancelled. The reasons, say the company, are “unforeseen delays."
