I have a Galaxy S5 phone, and one day a bunch of my apps stopped responding. I then started seeing lots of icons turning blank to the SD icon, indicative of apps that I moved to my SD card since I have the 16GB phone (a mistake on my part as I should have bought the 32 GB). When I restarted the phone, I saw all those apps remain with that icon, so something was amiss. When I went to my Storage Settings, I saw it say "Corrupted" under the SD card.
I have recently plugged the SD card into a USB card reader, then plugged that into a PC. I was able to read everything on there and even pull off copies of the files (I had a number of photos on there, so I was thankful for that). It seems to me the SD card can't be in that bad a state.
Anyone have a sense of what is going on here? Before I merely reformat my SD card (which I actually tried to do, unsuccessfully, a couple of times on the phone), I want to know that the problem isn't with my phone or the system software and thus will merely repeat itself. My phone is currently running Android version 6.0.1, awaiting an update that I have no space for thanks in part to this issue.
