I'm surprised that the factory reset doesn't resolve the issue, it always has for me, turning my slow old phones back into shiny new ones again.
However do be aware that your perception of what is slow changes as you use newer devices which perform better, making older ones feel slower than they did before - much like a shiny new work PC makes your home PC feel slow (or vice-versa) - so that may partly explain it.
Finally, I've just breathed new life into my ageing Nexus 7 (2013) tablet by installing the custom ROM "AICP" on it, which has made a huge difference to its performance & battery life. I recommend giving it a whirl on your SO's S3 - download from http://dwnld.aicp-rom.com/?device=i9300 http://dwnld.aicp-rom.com/?device=i9300 (though you'll need to read up elsewhere about installing custom ROMs if you've never done it before)
