What were they thinking? I have an android phone because I hate the iPhone ux. Now I have a phone that acts like the iPhone's dumber sibling. The update didn't even notify me that a new os was coming through. Rolling it back as soon as I can.
In your notification bar it should say that a new update will be installed at a time. If you tap on it, it should let you pick a time right for you or just update it on the spot. I don’t know how to cancel it, it seems Android wants you to have the most to-date OS you can.
