My SGS2 has an issue with my micro SD card. I have never had an SD card in it. Now I've got myself one (4 GB, Konig, Micro Secure Digital Class 10), it won't read it. I've never looked at it before, but now it says my SD card is 11,5 GB with 8 GB unused. When trying to move apps to it, it says there is not enough space free. Also, when there is no SD card in it, it does the same (11,5 GB SD/8GB unused/can't move). When using another SD card, it can move apps though. But my phone can't see them any more; it still 'sees' an 11,5 SD. What should I do?
