Does the Nexus 7 switch automatically between WiFi and 3G? I don’t know whether I should manually turn off 3G access when I’m home so it uses Wifi only or if it switches automatically.
Both the 3G and Wifi bar indicators at the top are always on, I would think that one of them would grey out if inactive? There seems to be no easy way to tell which connection type you’re using? Any help on this would be appreciated.
WiFi takes priority over 3G, so if you have a WiFi connection available it should use that.
Don’t the 3G icon arrows flash as data is transferred?
Googling around there seems to be some debate about whether you should manually switch off the 3G connectivity to save battery life, or whether you should always make sure WiFi is on if possible as it uses less power (as well as usually cheaper /quicker) . Can’t say I waste too much time on these debates myself as I’m not convinced the difference is particularly measurable.
Other people report switching off 3G for “peace of mind” – must admit I used to do that on my phone when on PayG – once cost me about £6 to receive a photo text message!! But I finally got a proper contract a few months ago so just leave both on.
Thanks – I have the most basic 3G contract, just to use “in case” when I’m on the road, so I don’t want to use up my time. Here in the U.S., AT&T is the only service provider so far for the Nexus 7. They give you the SIM card for free, then you sign up for a contract. The most basic contract is 250MB per month, which is what I have.
I haven’t quite figured out this switching yet; if I shut down and then start up, it seems to want to go into 3G, and both 3G and WiFi appear to be running simultaneously — I can’t tell. I would think there should be an “X” or something through one or the other of the icons in the top right, or at least an easy way to tell which connection is being used. I go in manually each time and turn off 3G.
