I'm with Verizon, and quite happy with my S3 on 4.1. 4.3 doesn't appear to offer anything that I need or want at this point, so I'd like to stay where I am until I have a compelling reason to upgrade. Right now, the only way I know of the update is if I go into Settings, About Phone, and then Software Update. I've never gotten a notification or pop up or nag to upgrade. I guess my question is, will it always be this way, or will I progressively be prompted to upgrade? I've read of some folks being relentlessly bugged with update notifications, though I don't know if it's carrier specific. If this happens, are there any options to prevent it? Any thoughts? Thanks.
