I'm talking, with airplane mode on. Your wireless/mobile networks off, wifi off...everything. Would just using GPS enable you to still use Maps and Navigation?
Guess not, I did some driving around and it seems to need the mobile network to work.
Not very useful if you leave the country unless you want to pay those outrageous roaming charges.
GPS will work by itself but you will either have to download the map info using wifi for google maps or buy a navigation app like navigon.
When you do airplane mode gps is turned off too. Just turn off mobile networks and wifi and check.

Hi guys,
I am new to amdroid platform. I've been using symbian before this. I want to know as to how do I auto use wifi when. Available without manually turning it on. Below is a use case scenario.
I have configured wifi as well as gprs. I have turned off background sync so as to conserve battery and the wifi is off. Now when my active sync want to connect to server to synchronize emails, it should auto check if I have a nearby wifi already configured. If yes, then turn on the wifi, sync the data and close the connection thereby disconnecting from wlan. If a known wlan network is not available, use the data plan of my service provider to get the job done.
Now I know for sure that when I've wifi turned off, the phone is not always connected to 3G. It uses it only if requested by an application. But when I turn ON wifi, it always remains connected to the known network. I want to avoid this for saving battery.
Please let me know if there is an app for that. I am using HTC DESIRE Z running Froyo (non rooted). I dont mind rooting the phone for this thing but only if a standard way is not available.
Thanks in advance,
Karan

I think Juice Defender does exactly what you're looking for.
Or Tasker if you really want to customize and make it location-based.
Good luck, and welcome to Android! I also came from Symbian.
Technically the phone can't know if there is wifi available unless wifi is on..
However, a tool like Tasker can use various contexts in order to determine if Wifi is to be turned on. For example you could use cell tower ID's to determine if you're at a certain (fairly wide area) location, like "at work". Or you could use GPS to get more fine tuned information, however it doesn't necessarily work indoors.
Or Tasker could also turn on Wifi if ActiveSync is running, assuming it's a distinct program it can detect.
I see in the time I opened the thread and responded someone else suggested Tasker as well. It's several bucks but it's well worth it, it does a LOT.
You should try an app called "Y5".
JuiceDefender does this for me. It must use gps positioning to determine if you are in an area that you have as a familiar wireless network. When I am home my wifi turns on and connects automatically. When I leave it shuts it off. JuiceDefender is great for many reasons beyond this.

GPS uses tons more battery power than just leaving WiFi on would. It might be using cell tower triangulation for a rough area, but I doubt it. The most efficient way to detect if familiar wireless is near, is to turn the WiFi on for a minute or so and do a scan.

WiFi doesn't use power to maintain the connection until it's needed, or something wakes it and it realizes its no longer connected. 3G uses power to track cell tower connectivity and stay connected, but it is very little. WiFi only uses more power when you're in an unfamiliar location, since it actively scans for new wireless networks.
[GPS] Your current location is temporarily unavailable.
- it's been like that for 3-4 days already, anyone know wwhat's wrong with it?
Settings/location and security/wireless network and gps
At least one of those needs to be on.

SOLVED.
needed to be wireless on in case if I was with wireless internet connected and my mobile internet was turned off, my bad.
basicly if you are at home, turn satalite and wireless setting on, they are both in Location settings.
I have Nexus 5 for over a week and waiting for case and screen protector. I left the plastic piece stay on the phone until the day before yesterday. I love the feeling of touch screen without any film or protector on it. I am learning this device.
I have router in my office powered but not working anymore, therefore there is wifi always on but not working anymore. Everyday in the morning, when I am in my office, the phone will detect that wifi auto, of course there is no signal. My mobile data is on all hte time. I have to turnoff wifi from the phone, otherwise I can not, for example, surf internet and check email. In the other words, no internet connection even mobile data is on.
So my question is: why the phone can not pick up mobile data automatically even there is a wifi? I was scared when i first had this problem because I thought my phone is not working. Is there any setting I can try to let the phone pickup signal from either wifi or mobile data automatically?
I'm interested also. Nexus 5 has a difficult time negotiating a signal when the signal is weak. At home, I get a higher powered signal on 2G so I keep it there. Today I noticed "no signal" and emergency calls message most of the day. (hubby's iPhone 4s is on the same service and he's getting the signal). I turned off Wi-Fi (which works perfectly, btw ) and phone signal connected. Treated it several times. Sounds like a hardware defect.

Your wording makes the question a little confusing, but I think you are saying your office router is turned on and available for WiFi connections, but has no internet connection itself to pass through to your phone.
Your phone connects to that WiFi for data, but can't reach the Net through the router. Meanwhile, you could get data through the phone data plan, but that does not work unless you turn off WiFi.
This normal. The phone is designed to use WiFi for data if a connection is available that you have authorized the phone to make. It won't use the phone data plan if connected to the WiFi, as you see. It cannot tell that the WiFi router is not connected to the Net.
I suggest you go into WiFi settings, click on the "ghostly" WiFi entry and tell the phone to forget that connection. From then on, the phone won't connect to that router and will use phone data plan.
What you would prefer would be for the phone to use its data plan as a fallback option, in case it gets hooked up to a WiFi network with no internet access, like at your work. Would be nice as an option, but not the way things work currently.

To prevent overage for users that may have limited data plan, the device will always try to use WiFi when enabled. If it can't connect to a WiFi network, it will look for the mobile data if enabled.

In your case, since WiFi is "available", there is no setting on the stock ROM that will tell the device to connect to mobile data instead. Think about it this way - your phone is connected to the LAN using the WiFi network. It can reach the gateway, and has a valid IP. It doesn't care about whether it has WAN connectivity or not. So, it assumes that you are connected, and have connectivity.
You could look for apps on the play store that will actually check for WAN connectivity and if not available, disable WiFi (so that mobile data is used instead)
But, the part that I don't understand is this: If you don't have WiFi available, why do you even enable it? Turn WiFi off (disable wifi scanning in advanced settings of WiFi as well), and let mobile data take over instead. Or do you need WiFi elsewhere (say, at home)? If so, there are apps like Tasker that will let you set up profiles to enable WiFi when you are at home, and disable it when you are at office or other locations.
Thanks all for your very helpful reply. Sorry for my poor written English.
My office router does not function properly and I am to lazy to power it off, so my phone still can detect it but of course there no internet access from the router.
I now know I just need turn off wifi from phone and the phone will pickup mobile data auto.
Does anyone know if it's possible to get GPS on the watch without the phone being paired. Everytime I try tracking in s-health it will only track my route if GPS is on on my phone. Similarly in here maps I can't get a location fix if GPS is not turned on my phone.

I know that the LTE version can transmit GPS location without being connected to a smartphone. I'm not sure about the BT only model.

I also have the LTE version. It works but you have to go into the settings and turn on the location in settings. I don't know how it works with BT version. You may want to go in and see if you have location settings.
As far as maps, you may be out of luck. You will still need the phone to send the map to the watch. With the LTE version I can get a map or navigate in standalone because I have a LTE connection to retrieve the data.
Now I did notice one thing. When I am connected to my phone, my S3 gets GPS from the phone and not the watch. The GPS on the watch only goes on when not connected to the phone.
So we all know that there's Wifi Sharing capability on the s8.
I want to know if there's a way to bypass needing to be in Radio ON mode. The reason I say this is because, I want to use this on the plane. I want to be able to buy one internet access plan on the flight then be able to share the connection through Wifi Sharing. But the issue is that we cannot share wifi in Airplane mode?
I have the dual sim version on the phone. I figured keeping airplane mode off and going into the settings to turn off data in SIM1 and GPS would be ideally the same as airplane mode. Is this true? Or is there something we can tweak to use wifi sharing while in airplane mode?
Why do you feel that you need to have airplane mode turned on? Just enable wifi sharing and forgetaboutit.
I'd say because the phone gets crazy hot and if you're not tethered to a battery pack, you won't last an hour with the screen off.
