Formatting your memory card on a PC may cause
incompatibilities with your device. Format the memory card
only on the device.
In Idle mode, select > Settings > SD card and phone
storage > Unmount SD card > OK > Format SD card >
Format SD card > Erase everything.
2) Do not enable: a) Kies starts automatically 2) Kies displays SD card in Windows Explorer
The problem is not the phone. It is wrong formatting of the SD card (“When in doubt read the instructions” and issues with the very quirky Kies program.
