Luckily, my phone's connectivity has been pretty fine for my useage...mostly. BUT I like to toggle between WiFi, 4G/3G and off somewhat frequently (maybe a few times a day) and I often have an issue going to 4G/3G--as in when I switch to it often times it doesn't actually switch for several minutes if at all. Sometimes restarting helps. I'm using switch pro for my toggles. Is this a problem other people are having? Should I just use a different app? Thanks.
