The Galaxy Core comes in a white and blue versions, and we have the white one for test. The build quality is solid, with no screaking parts. The handset is thin rather than thick at 9mm ( 0.35”) . It is very lightweight, tipping the scales at only 124 grams ( 4.38 oz) . It is also relatively compact and easy to use single-handedly, plus it won’t stick out of your pockets like some larger phones. Under the easily removable back cover are a user-replaceable battery, a microSD card slot and the two micro SIM card slots.
