Mobile data while on wifi?

    I have a Sprint Galaxy Nexus. I notice a lot of times when I am connected to wifi, I see the up / down arrows over the signal bars, which I believe indicates mobile data is being transferred. If that is what those arrows mean, why is my phone using mobile data when it should be using wifi?

    is your mobile data actually being used? Like if you go to settings and Data can you tell if your using data...

    but the up and down does indicate data usage but if your wifi symbol is up then it should be using Wifi not mobile data

    I will have to check tomorrow before I leave my house. Today I used both 3G and wifi. Attached is a picture of what I am seeing. Both wifi and 3G appear to be transferring data.

    The arrows mean you have a connection. The arrows will flash when actually transferring data.

    Use a task automation program to turn on and off mobile data when you connect/disconnect from wifi if you are worried.

    When 3g is actively being used, doesn't a 3g icon show up ('3g' to the left top corner of the signal bars)? On my Sprint GNex, it does.

    Yeah, you are right. I just saw the up / down arrows on the signal bars and didn't think I used to see that when connected to wifi, but I probably just don't remember. Thanks everyone for clearing it up.

    I used Tasker to do this - turn off data when in range of saved wifi, turn data on again when out of range of familiar wifi'. I had it working perfectly - even gave it a 15sec delay before doing anything in case i stepped just outside of range for a second (common with our shitty radios on the gnex).

    MAJOR drawback for me was that you can't receive MMS messages when data is off. If I could find a way to alter the Tasker profile to turn data on when receiving MMS (then turning off again), it would be great.

    All that said, it doesn't save much battery to have data off while on wifi.

    I think a lot of people, myself included, would love this!

    I can't remember, but does your phone show it received a MMS message when data is off? Unless the phone receives MMS notification through the standard SMS system, your phone would never be aware it even received an MMS. That's why I'm wondering.

    Although about the data indicator. I think its just a weird bug. Sometimes my bars get stuck at whatever position they were when I turn data off, and they never go away until I re-enable data for a couple seconds.

    I actually do this exact thing through tasker. My context is an event which is received text set to mms. I have a task to turn off wifi, wait 2 minutes, then turn it back on. My data is set to turn on when wifi is off so this gives me a little time to download the pic.

    The arrows on WiFi just mean that your WiFi connection is working to send something up or down stream.
