I have I think a 16GB Micro SD card. But I can't seem to be able to use it. I can't save nothing on it, and when I installed this app Astro, a file manager, I still couldn't do nothing with it. My apps are saved to my phone, and the pictures I take with my phone and the videos are also saved into my phone. Only songs are saved into my SD card. Am I doing something wrong? or is the Micro SD card only made for songs, and not the pictures and the videos and the apps? I have an app to back up my information called m:IQ, and there it says I used up 46% phone memory, and only 2% of the Storage card. So can anybody tell me what's wrong exactly? Thanks in advance.
