Often what is seen is the indicator disappearing over and over and then a white 4G with signal bars, indicating data service is available though it isn't. Even when the indicator is blue (connected to google services) there is often no data connectivity as the indicator does not instantly refresh. Those people in 4G areas will see the biggest issues compared to people on 3G because when the 4G serivce isn't working right, EHPRD services to hand off to 3G don't seem to either. 3G EVDO phones work fine because the 3G network is reliable. 4G phones running on 3G will have less issues because they rarely need EHPRD services, is my guess.
