I installed a 16gb SD card about a month ago in my phone, and set it as internal storage. About a week ago the phone kept showing SD card removed. I'd pop it out, reinsert it. It'd last for a little bit and then the phone wouldnt see it anymore. Now no matter what the phone isn't recognizing my SD card. I can't even get my SD card reader to recognize the card to back up any pictures etc. This is the 2nd time its happened to me since September. (Previously with a 64gb sd card) Last time VZW sent me a new phone. This is also a different SD card then when it happened last time. Any suggestions?
