I purchased a SanDisk micro SD card for my samsung galaxy s4 and the card seems to somehow interfere with the phones sound/ speakers function. The card itself works perfect, but after I inserted the card I noticed a problem after my alarm went off but didnt ring. My volume will be all the way up but it will no longer play the normal phones notifications such as the lock screen sound, I checked videos and music on my phone and reset the app preferences before I realized the sd card was the problem. When I removed the sd card my sound instantly worked again. Does anyone know why this could be happening and of a way I can keep my sd card in my phone and have my sound working at the same time?
