sorry if this has been asked before does the Galaxy S4 work well on a 5ghz wifi band. Since upgrading my Sprint S4 to 4.3 I have been having some Wifi problems and I wasn't sure if it was my new router or not.
My AT&T model has been working fine on 5 GHz since the update. Good thing too, since the 2.4 GHz WiFi has been horribly erratic ever since I applied the update.
