Re: what is in samsung galaxy note software update available from the phone?
What update it is trying to get you to install, depends on what is currently on your device. The OTA server will keep prompting you to update the next incremental update. OTA updates typically need to be installed in order, and cannot be skipped over.
Not sure if the updater process can be froozen/suspended. Particularly if you are on an older firmware version, since this feature was not added to Settings until Jellybean. And it may require root to freeze the updater process, anyway.
