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

Ok, this problem seems to be happening for how many years now? I have thee Extreme 32gb and one Ultra 32gb micro cards that have all failed in my Samsung S4 Mini. None of them lasted for more than a week. I don’t have any problems when I use a Sandisk 16gb or 8gb micro card. So to say the phone is the issue does’nt make since. 

When will Sandisk admit that their 32gb cards have issues?
