Hi all, I've got a little problem. My Samsung Galaxy Gio was running fine with a 2GB (there's not class on it but i think it's class 2 EDIT: I tested it and it's a class 2) but it was full after 2 days. So i ordered a Kingston 16 GB card and especially took a class 4 instead of 2. But now it seems like it's slower, when i play music it sometimes stutters, when i play coindozer, which i believe isn't really a big application, it just hackles stutters and hangs a little. Could this really be the SD card or could something else be the problem?
