A few weeks after I got a new microSD, my phone started randomly force closing apps, regardless of whether or not they are in use, and says the microSD card has unexpectedly been removed. It then restarts itself and says that the SD card is damaged or corrupt and may need to be reformatted. The microSD is a PNY 32GB class 10. I did reformat it the first time it happened and checked for errors but nothing came up and it still does it. Any ideas?
