1) Samsung sucks, they can't even make a device with a notification menu that can pull down smoothly, so no points there.My Note 3 reloads games, google chrome tabs and apps like crazy and it has 3GB of ram. If you think iPhone is the only platform with the reloading problem, you're wrong.
2) Android Memory management in general is pretty terrible. The issue with the iPhones and iPads is simply that it is running out of memory and cannot keep the webpage in memory so it dumps it.
