Nearly two months after Samsung announced a global recall of its new Galaxy Note 7, the electronics giant reportedly still doesn’t know what is causing some phones to overheat and catch fire. And that mystery is delaying development of the Galaxy S8, its next flagship phone, the Wall Street Journal reported Sunday.
Samsung did not immediately respond to a request for comment, but a spokeswoman for the company told the newspaper that it is still searching for the cause of the phones overheating.
