remove apps like Browser
Samsung seems to provide similar software on its devices, so this procedure from a different Samsung device (Galaxy Tab 3) will probably hold.

Open the Menu > Settings > Application Manager

Use the right-most panel "All", and scroll the list to find the application(s) you want to disable. Click the button to do so (generally labelled "Disable" or "Turn Off", or similar).

You generally cannot uninstall pre-loaded apps without rooting the device.
