Yeah… I love latest Samsung Galaxy S II firmwares because they are always the best, performance improve and bug fixes. What are the new features of the latest official Samsung Galaxy S2 DXKI2 and XWKI4 Firmware. Personally, I did not test them yet. However, based on feedback from who upgraded to the latest official Samsung Galaxy S2 KI series ~ USB JIG and USB host support are no longer working. Well done, Samsung…
