Hi Guys,
I have a lightly used Gopro Hero 4 Black. When viewing my footage back there is a huge area of the screen momentarily flashes green, coupled with a crack like effect. Looking on Gopro sites this seems to be a re-occuring issue across other models too. Has anyone had similar and what did you do to rectify it.
Thanks,
Ian

I have no other cards to test it on, so will have to bite the bullet and buy a newer faster card.
