My Samsung Galaxy Note 10.1 2012 appears to have slots for memory cards, but I don’t know how to insert a card. How do I open a card slot
On the lower part, where’s placed the stylus, on the left side the should be 2 or 1 slots ( depending on the fact, if you bought the model with SIM card or not), lift the door of that slot, and insert the SD card as shown on the door’s pic
