Why doesn't my phone read the SD Memory card?

[AC Question]

Why doesnt my phone read the SD Memory card?

My phone ran out of space so I bought a memory card but it doesnt seem to be reading the memory card.

Insert your microSD card in PC and try write on it.
May be your card is demaged.
If card is not damaged:
1) move apps to sdcard. Not allphones move apps and data of apps to sdcard.
2)if your phone can't move apps to sdcard try use sdcard app mover.
3) try to use new ROM from XDA-DEVELOPER.COM
