My galaxy s4 will not notify me if I get a new Snapchat, Facebook message, tweet or anything that requires data. I can go on these apps and they work fine but the notifications don't come unless I'm in a Wi-Fi zone. Also YouTube videos take forever to load even though they are a seven second video and I'm in an LTE zone. Does anybody know how to fix this? I'm with telus on the Canadian s4 running the new kit Kat firmware, rooted.
