Re: Not sure if using 4G...
When connected to wifi, most phones will only connect to 4g cellular service when certain types of data are used, like system updates from the carrier and i believe multimedia messaging uses it, too. Also, my GS3 will use cellular when trying to get a GPS fix for triangulation.
Other than that, most other data should default to the wifi.
Note2 or Note10, that is the question
Re: Not sure if using 4G...
I had the same confusion when I first got the one x,my old phones only showed the type of data connection that was in use. The one x leaves the 4g to show you the type of signal even when connected to WiFi,but if you are connected to WiFi the one x won't use your data unless its like a system update or something,everything else data wise will be over WiFi.

You're using Wi-Fi unless sending mms, it uses 4G then.
