[Q] SD cards suddenly not working
Hi. I bought my Note 3 last year in October and I used my 16GB class 4 SanDisk card. It worked perfectly, it's just that it was pretty slow when saving 1080p/4K videos.
So I decided to buy a 64GB class 10 SanDisk card from Amazon. But I had many problems with the card, images and videos were corrupted etc. Though when trying the card in other devices it worked fine. Also tested it in my computer with software that filled the card with 64GB of data to verify that it was 64GB. I also manually filled the card with 64GB of images and videos and nothing was corrupt.
So I decided to just use the phone without an SD card and that is what I have been doing for the last 5 months.
Now I wanted to use my 16GB card again but it isn't detected at all. I have tried three different cards but nothing happens. I have tried everything I can think of, factory reset amongst other things.
I'm using stock rom and it isn't rooted. Do you have an idea what could be the problem? Perhaps it's simply faulty somehow?
