How long is it supposed to take to install the system update, I think from 4.4.2 to 4.4.3, on a Nexus 4?
I downloaded the 70 MB and after the phone restarted, it attempted to install the system update for the last 2+ hours. The progress bar starts, goes all the way to the end, the screen goes black for a split second and then the install screen appears again with the bar starting at the beginning again. The phone is not brand new anymore, but I would expect it to go faster.
If this is too long and maybe an error occurred, can I cancel the update process by pressing >Vol-Down + Power Button< without having to worry about an unusable phone afterwards?
