I've noticed that even when I have 3g or 4g, certain apps never connect to the Internet. The apps I've noticed that have this problem are sound Hound, Google now search, spotify and words with friends. These apps will fail to connect to the Internet and say I have no signal, yet I can open Google Chrome and open a Web page no problem (even pages I don't visit that aren't stored in cache) or use the Chive app. What is the problem here? Anyone else experience this?
