I was eager to update my android device to KitKat 4.4.4 but all I got is a new problem. In Android the procedure for system update is settings>About phone>System update. Isn't it? Whenever I tap on system update the system update tab opens and closes immediately. So I'm unable to update my OS. It happens every time I tap it. Meanwhile when I try to power off my device the system update opens and I can not access that tab since the shut down process will be processing. What is happening I don't know. Is there any alternate way to update the OS?
