32GB Sandisk Micro SD suddenly stopped being recognized by Galaxy S3 phone

Memory Cards Mobile memory, professional cards and all other st
52

Does anyone got a fix on this without sending microsd back to Sandisk.

This just happened with two 32 GB microSD I have but i bouth then on 2012. Don`t think they are going to return this on warranty.

Moreover, I bought in US and I`m in Brazil now.

Thanks
