But then does it bring up a little icon on the phone to say the memory card is working?
It only shows an icon at the beginning (when you enter the SD card), when the phone is scanning the SD card for media. After the process is complete, you get no notification about the SD card being inserted.
Please be advised that WAVE and GALAXY S have different opperating systems, so the functions are not the same. Even though they run the same TouchWiz skin....
The SD card is not supposed to be formatted in any special way. I can read any SD card in my phone. Make sure that the SD card is not passwork protected (this is a feature of some Nokia phones) or that your phone is not deffective.
You can double check by connecting your phone to the PC using a micro-USB cable, with the phone set to Mass Storage. See if you get TWO "Removable drives" on your computer: one is the SD and the other is the Internal Memory.
Hope this helps.
