The card is used with a LG GS290.
Problem:
--------
The card is recognized, but can not be used! - Because it is not formatted.
Styling with LG GS290:
-------------------------
So once over the phone formatting (cube -> Phone -> Memory Status -> Memory Card -> demand by pressing YES -> Enter security code 0000, after which they should be formatted).
The format did not bring anything. So the PC / computer formatted with 32kb per storage unit -> phone -> Card purely -> mobile phone.
And only then it was for me with this mobile.
Otherwise, there is no problem with the lock switch as described above.
