My LG P509 Android Smartphone's SD Card won't work. I didn't drop it or the SD card ever in my life. This happened out of nowhere when listening to music. Message appeared and said SD Card Removed. Please insert a new one. Help please?
Has your SD card worked well before? How old is it and what brand? I'd suggest inserting another card into the phone and that SD card in another phone so you can confirm if it's because of the card and not the phone. My dad had a similar problem with his SD card on a Samsung Galaxy S. I gave him my Sony card and ever since he had no problems. Keep in mind that cheap cards don't last very much.
