I have my phone set to CDMAonly (no 4g) and smart actions is set to turn off data when the display is off. Whenever I turn on my screen back on, it takes a solid 15-20 seconds for the 3G to reappear. Sometimes it doesn't come back at all without toggling airplane mode, data, or something like that. This doesn't happen with 4g at all. Yes, I have set a smart action to turn 3g back on when the display turns on again. It doesn't help at all. Anyone facing the same problem and/or know how to fix it? Thanks.
