Please dont update it to lollipop cause I updated it and later I regreted about lollipop huge battery drain and overheats on normal usage I just reverted back to kitkat 4 days ago and its working great better than lollipop its smarter than other mobiles its a gerous massive screen, screaming quad-core processor, and refined S Pen skills. It also has long battery life, makes clear calls, and takes great pictures
