I've had two GoPros for years Session and Session 5 Session 5 was weird when I first bought it and it only got worse in two years of ownership. even record ten seconds no matter what I'm doing. Runcam looks good. If it actually works out of the box it does the same thing as a GoPro I bought to replace so I don't know what to do. I can't tell you how many SD cards I've used and how many times I've formatted and reformatted them. I was hoping this would be a better replacement. but I just can't get it to work! EDIT: I had to do a very complicated and lengthy SD card formatting and this APPEARS to fix it (not pro though) so I have to give it a better result!
