I have a Galaxy S3 (GT-I9300), my current Android version is 4.0.4.
I am trying to define software updates for it, via the Software Updates screen. (Settings > About).
However, I get "Unable to connect to network" every time. What network is it trying to connect? Can I define it? If so, what should I define it too?
Also, will software updates allow me to update to 4.1.2? If not, how can I?
Can anyone please point to a resource which explains it? (Or even better, answer it here).
If I'm lacking any technical details, please leave a comment and I'll edit my question right away.
