LG enV VX-9900
How Did People get MicroSD to work???
Did you need usb adaptor cord?
If you are having difficulty getting your phone to recognize your MicroSD card, try this.
Format the card in your computer first using a USB card-reader.
Insert the card into your phone. Format the card in your phone.
If this does not work, exchange the card where you purchased it claiming "this one doesn't work in my phone for some reason"
If that one doesn't work in your phone either, it may be a compatibility issue with that brand, OR, your 9900's MicroSD slot is damaged in some way. 👀 👀
Hope this helps
