Samsung Software Update, also simply known as ‘SOAgent’, is a pre-installed app in most Samsung smartphones. The app checks if there are any software or security updates, notifying you if there are indeed updates or downloading them instantly.
Because this is a systems app, it has certain privileges such as Internet Access in order to regularly check if there are any updates available. There have been times that this feature has caused problems for the users because it can drain the battery if it doesn’t work properly. If that happens, it’s important to keep in mind that you can deactivate this feature using the list of installed apps.
Samsung Software Update is a systems app that will simply make sure that your Samsung smartphone is up-to-date. Needless to say, this app is totally useless for any smartphone that’s not Samsung.
