Why my ALCATEL doesn't detect my 32Gb MicroSD card?

[AC Question]

I have a 32Gb Kingston MicroSDHC class 4 card, and an ALCATEL ONE TOUCH 5020A running Android 4.1.1, I'm using this as a replacement pone untill the Huawei Honor X5 arrives. I've already formatted the card into FAT32 but my device doesn't detect it, the device is rooted with KingoRoot but I haven't deletd any system app.

A little help please? Really need to get the SD working because I use it on the work and it's more practical to use my phone rather than having a laptop everywhere.
