Samsung has today announced the Galaxy S II Plus, a slightly improved version of its hugely successful Galaxy S II, which first launched in April 2011. The handset boasts a 4.3-inch Super AMOLED Plus display, a 1.2GHz dual-core processor, and 8GB of internal storage (expandable via microSD card). The handset looks identical to the original Galaxy S II, which only makes us even more confused as to why this handset exists.
