So a few weeks ago I purchased a 128 gigabyte SanDisk microsd off of Amazon, I got it in the mail a couple days later and popped it into my phone and it worked instantly and perfectly. Well a few days ago my phone was acting odd and wouldn’t charge so as I was talking to my stepMother about it and while looking at my phone she took my SD out because she knows nothing about technology. Regardless, when I got it to start working again it told me that my SD card was corrupted and that it needed to be formatted. I tried but it got to 40% and then errors out. It does that everytime. Now it tells me it’s unsupported and I’m utterly confused.
