A:AnswerI have not yet used it with my GoPro, but it works very well in my Yuneec SteadyCam . I will try it in my GoPro, though probably not for time lapse video.
A:AnswerWhen I was researching micro SD cards, this card was mentioned a lot as great for use with the GoPro cameras; since I haven't used it with one, though, I really can't speak to any performance issues in the camera. ...
A:AnswerI would imagine that as long as you format the card to a common file format that can be read by both the camera and the tablet (in this case, I would imagine FAT32 or possible extFAT (the camera may not support extFAT but I know that the tablet will because I have a galaxy tab s 8.4)) then you should be good to go.
I've done the transferring of SD cards between devices but it was from a DSLR to a camcorder and I don't remember any issues outside of the additional folders being written to the card itself
