I haven't been able to get smart alert to work on my phone since I've owned it, even before I rooted it. This link talks about how it might just be a kitkat/s5 issue: http://forums.androidcentral.com/sam...orking-s5.html

As for direct dial, mine it's still working, so I'm not sure what the problem would be there. Did you freeze or uninstall any stock apps after rooting?
