The Sandisk micro SDHC card with 8GB Easy to install in the mobile phone Samsung S5230. The memory will be automatically detected and can be used without any adjustment. Delivered was actually a card with imprint (4) So Speed Class 4. I have not done, because that is not relevant for use in mobile A speed check. With the adapter, the card can also use, for example, in a camera. Due to the low price and the impeccable function this card can be recommended without reservation.
