If the GoPro Hero 4 has "microSD", then it should work...

I don't know, I need it in my Canon Eos camera. It works there without problems

marginal note: would recommend these: Sandisk ExtremePro microSD A1 (32GB, Class 10)
new generation and even cheaper at the moment.

problemlos.

The microSD card is used in a GoPro Session. Therefore, it should work without any problems.

I can't judge! I have no problems using the SD card in a TomTom Go 6200.
