How can I ignore the AT&T software update? (Update 2016-01-09: I got rid of the phone after it auto-upgraded to Android 5, so I don't have this issue anymore.)



I keep getting this message every 10 minutes or so on my Samsung Galaxy S3 (non-rooted Android 4.1.2):



How can I ignore it?

I want to skip this update as the penultimate one introduced some nasty bugs.

EDIT: Apparently I cannot kill the AT&amp;T service:



Also, I restarted the device and the AT&amp;T service is launched at startup.

So I tried to remove the AT&amp;T service from the startup using Startup Cleaner 2.0, but the AT&amp;T service still get launched...:
I called AT&amp;T, and this is a mandatory update. Other than rooting, there's no way to avoid the message. You can avoid the download by not going onto WiFi. If you install the update, you need to re-enter WiFi passwords EVERY time you reconnect to a WiFi network. Horrible! I'm avoiding this thing even if have to keep hitting the home key when the message pops up.
