this exact sequence has just happened to me... have I now got a useless phone?
did this happen for you after installing the latest android update? it did for me, bit of a coincidence...
is it possible to 'remove' the slo-mo, or convert the video to normal speed?
i have edited the video in Google Photo and saved a copy at normal speed, however when I go to share it, it plays at slo-mo speed?
