Just got an SJ4000 camera for christmas but for some reason it doesnt like the sd card i put in it. Can anyone recommend a micro sd card which will definatley work with this camera?

Have you tried re-formatting the card?
It appears the maximum size allowed is 32Gb and it needs to be formatted correctly.

Yeah ive tried reformatting it. and its 32gb. Card works fine in girlfriends phone and her card works in my camera, her card is only 2gb though so dont really want to use that

Mine works fine with a 32Gb

It is fussy about cards , cheap cards dont work ive found, i use sandisk and its fine , 32gb and class 10
