not sure man i personally hate samsung strictly because of how awful touchwiz is. Your probably new to android but id highly recommend rooting and flashing a stock android rom on it. Read up online and on XDA forums. But yeah only way to remove it is changing the launcher, that'll allow you to chose what kind of page icons you want
Nah not new to android
I just never had a galaxy and never seen the lititle house before
I've been rocking the htcs lately
