This is inaccurate. I have had my phone (Galaxy S7) for 6 months. It has always been kept up to date. This morning at 5am, it generated an audible alert for the system update even though there had been no prior notification of any kind. The phone was on do not disturb.
I understand that updates are important, and that they may become available in the middle of the night, but the whole point of do not disturb is to let me sleep. There's no reason the update couldn't wait 3 hours.
" You should have gotten an earlier notification on the update at a more reasonable time. It's pretty obvious when they are available and hard to miss on the phone. If it had been done then it wouldn't have awakened your household. I know 99% of the folks with smart phones just use them normally. Next time if you miss the pop up for the notification or dismiss it will park itself on your notification bar. If you see that icon you know something is timing out waiting to wake you up at 2am. Might want to deal with it before bedtime then. Another less desirable option is to turn down the sound before bed.Not good for being available in an emergency. Best option: Deal with it before it deals with itself."
