I wrote a late review because I thought it's not gonna work but fortunately it did. I had to use two phones to compare whether the product is defective or not. It worked perfect with my Samsung S5 phone the moment I put it in. But had to work my way a bit with the Samsung J5 which I specifically bought the micro sd card for. I'm able to download videos, pictures and moved apps without any problem.
I bought this to replace the 8 GB memory card that came with my home surveillance system. This card has been working flawlessly and I'm very pleased with it.
It is a great product. Before buying it, I did my own research as some of these are made of materials that are cancerous. I came across this one which is supposed to be safe. Like I mentioned the only issue was with the bud falling often. That is why I did purchase a protector to keep it inside it
