Earlier today my phone went crazy on me and for some reason I could not use any apps that I have on my SD card and I am curious as to why it has done this and how to fix it if I can without having to buy a new SD card. My phone will not let me format my SD card through my phone but when I put the SD card into the card reader and open the files on my laptop everything is there and working. Also when I have my charger hooked up to my laptop the applications work but when it is not plugged in they do not work... some help me im stumped 

) Hope this helps. Welcome to AF
