I've been running Android 11 on my Zenfone 8 since last year, when an Android 12 update killed off the ability to make phone calls or send texts. To prevent a similar debacle, I used the developer options to disallow automatic updates. Four days ago, I get a notification that I can't dismiss that there's an update available. I had an 8 hour drive ahead of me, so I ignored it. Imagine my surprise when it starts downloading the update automatically when I get home to a wifi connection, and continues downloading even when I turn wifi off.
WTF Asus? How do I stop this from happening in the future? I'd rather not go to the trouble of rooting my phone to keep you from hacking the OS on me. I can go through the process of backing up the phone and downgrading to Android 11 again, but if this is going to be a regular occurrence, that's going to get old in a hurry.
