Anyone could pls explain how localization now works on 4.4.2?
In 4.3 I could have localization thru 3g on and gps off, then I'd turn gos on with a switch when using maps on nav app, and ogff again when finished.
Now all I have is a switch that enables/disables localization and an option with 3 way of working: 1. gps + 3g + wifi, 2. Gps + wifi or 3. gps only.
I am lost... If I choose option 1 than is my gps always on sucking battery? If I choose 2 how can I easily enable gps when in nav app? And if I choose 3 how can I still have google localize me thru wifi when localization is off?
This is so stupid, they should have kept 3g and gps localization separate...
Hi! Please see this how to for guidance with GPS settings in android 4.4.

Apparently the options are practically the same as in 4.3 and just a little bit changed on 4.4.
High accuracy = Should enable both AGPS & onboard GPS Sensor to fetch your location.
Battery saving = Should only use AGPS.
Device only = Should only use the onboard GPS Sensor.
where
AGPS = uses an internet connection(3g and/or WiFi) to get your location.
GPS = uses the built in GPS chip inside your device and connects to GPS satellites to fetch your location.
So in your question.
High accuracy mode in android 4.3 is just like checking both "GPS Satellites" & "Google's Location Service" option at the same time.
Battery saving mode in android 4.3 is just like checking only "Google's Location Service" option.
Device only mode in android 4.3 is just like checking only "GPS Satellites" option.
You could just switch to high accuracy mode when you want to use maps with GPS on and switch back to battery saving mode when you're done using it.

Anyhow, before I could leave 3g localization on all the time and enable/disable gps with a switch, now I have to go into the option to do this

There really isn't a need to keep GPS off while not using a location app. Your phone will only turn on the GPS receiver when an app asks for your location. It doesn't just constantly stay connected to satellites while the phone is in your pocket. I always have GPS enabled and there is no effect on battery life.

Actually aGPS still uses satellites. It just uses your data connection to do one or both of the following:
1. Download satellite reference data to know the position of satellites more quickly for a faster fix
2. Uploads your GPS signals your phone gets from the satellites to an external server which can calculate your location more accurately using things like atmospheric conditions and weather
aGPS is why a phone can get a GPS fix in seconds while a dedicated GPS device might take much longer bc it has to download the reference data from the satellites itself.
What you are referring to is a network estimated location, which isn't the same as aGPS. In fact your phone will always have aGPS enabled if you have GPS enabled.

Well if that's the case with AGPS care to explain how Nokia Maps were able to pinpoint my location years ago when I am using my good old n80? It has assisted GPS but no onboard GPS and as far as I can tell nokia map works on that phone.

Not sure if there's any widgets for the new GPS settings of google. TBH though for every upgrade of android eversince jellybean I'm starting to get turned off from android. They're like taking out the features of android 1 by 1.

Got to say i hate the new GPS switch layout, was wondering what the hell they'd done when i first saw it.
Someone will create a switch for it somewhere along the lines, in the mean time just leave it on battery saver mode and switch to high accuracy when you need to drive or something similar which requires full use of GPS.
If the community (us and everyone else) makes enough noise about it they may bring it back.

well as @301stSpartan says, even if in high battery mode, it seems the gps is fired only if an app is requesting, so at this point i wouldn't mind and leave it always in high mode

Yea you could but the amount of apps that fire up the GPS is quite a lot, and if youre inside then it's going to try to communicate with satellites and it won't be able to, it'll hit battery, i've no doubt about that.

Is this function in our Kaiser? I've enable it from the Kaiser Tweak but today i tested it when i was in a tunnel....it did not work at all and the tunnel was 4 KM long....it should have had enough time to get a fix if it was working.
Is the Assisted GPS what i think it is?
How do you expect to get a GPS fix in a tunnel???
AGPS is basically what the QuickGPS app. does: it downloads sat. data (satellite locations) via a network connection from a server, so that TTF (time to fix) is reduced, since the device doesn´t have to download above data from the satellites themselves - which is slow....
Hope I was not too unclear, doing a search will give you much more and detailed info about how GPS works......and it doesn´t in tunnles....
As mentioned above, the AGPS uses server information (via cellular network) to locate the GPS satellite for a quicker fix and hash conditions. For a 4KM tunnel, I'm sure that your phone would have lost both GPS and network signal.

Thats correct, there are som applications that tries to estimate where in the tunnel you are when the fix is gone. But I suppose this is a function of the application and not the GPS hardware
I stand partially corrected........ http://en.wikipedia.org/wiki/Assisted_GPS

Which is why the title is "Assisted GPS".....I've done some search on AGPS and it's suppose to use the cellular to still get a fix when in the tunnel. Well....i read it sometime ago way before Kaiser was out and this was actually one of it's talked about feature in Kaiser. Using the Kaiser Tweak, one can enable this feature but i've tested it today in the tunnel with strong cellular signal, the GPS is dead until i came out of the tunnel.
I guess it also has to be supported by the particular program. Many TomTom PNAs have a dead reckoning mode which shows your position in a tunnel based on your "entry" speed for about 30 seconds, than the position freezes in the tunnel. Now that of course has nothing to do with AGPS, but it´s a way of overcoming temporary signal loss.
Best way would be to have an inertial sensor built into the phone like in fix-mounted car-navs......but then again, that would be overkill....
You have to remember that the Assisted GPS (Cellular network mode) relies on the fact the network itself supports the feature. I know most in the UK don't have it turned on in general use. They only allow it to be used by emergency services and the likes.
Perhaps that's the same in your country?

Thanks guys for the input.
I know SGS has a lot of issue with GPS. Here's mine. I've cold start and standalone set-up in lbs test mode. Now the problem is it'll lock on to satellites in a matter of 20sec with 15m accuracy only when connected to wi-fi couldn't check for gprs since sgs doesn't save my apn =(. But with wi-fi switched off it doesn't speak to any satellites forget about getting a lock on them. Doubt here is, isn't standalone mode supposed to be GPS working without any data connection of any sort or am I missing something here? Kindly clarify. Also what does MS based and MS assisted mean in the test mode. Checked for GPS with Network Provider selected in test mode. I get accuracy of 3.8km here at my home....
Thanks & Regards

I just tested indoors (rainy here) and the SGS did get a lock. I've switched off cellular data and wifi, cleared the AGPS data with "GPS Status", and it took a long time (few minutes) to get a lock.
But that was indoors, where it always takes a bit longer to get a lock.
I tried it outside last evening and it would only see the sat's no lock =|
I was curious as to why there is a button in the notifications menu to turn GPS on and off. I started to look in to it and discovered that there is indeed a GPS chip in the wife only version, or there seems to be anyway!
My question is, what does that chip exactly do? Does it only pick up your location? I can't seem to find any places around me with wifi off. I'm assuming that means all the map and location data is delivered over the internet through 3g or wifi. Is there anyway to use my device as I would a regular GPS device? I know it has all the features but can they work through the GPS chip like they do in a GPS device? Or is there anyway to get this to work?

Ok the wifi is mainly just for accessing networks either open or via ssd and password. You can also connected with mobile AP if your mobile has this option.
The GPS on the other-hand is for mapping and location based services like navigation etc (you can use copilot and several other gps based apps with the P1010). Some of these apps will also piggy back any Bluetooth and or wifi connections that are available for further triangulation if needed. So if you have any apps like various weather and navigation then the GPS is required (but also your location can be shared via your wifi and opt in to give this info through google).
Hope this helps

you can find your location via wifi, enable your wifi and turn gps on, you'll find your coordinates, but not that accurate compare to 3g
Hello everyone.
I just wanted to get your attention on a major Android OS (Kitkat) bug in the interaction between Wifi -> Advanced -> Wifi Always Scan and the Location Service. Clearly the bug doesn't happen every time, but sometimes it does, and obviously I'm talking about stock rom / kernel / no root / locked bootloader.
Althought I can't prove it, this might also be the cause of the current GPS / Navigation issues, currently being reported here.
What makes me link this to that issue? Because when Wifi Always Scan bugs out, it prevents my phone to acquire a location even from the 3g network.
That would explain why in that thread many people report that they could navigate with Device Only, which doesn't use 3g or wifi for location, but they had major issues with High Accuracy, which uses all three sources.
Please take a minute to star the issue so that Google will hopefully fix it faster.

Thanks for your useful contribution.
It doesn't waste battery, it saves it. It enables to use the wifi location using a lower power state of the wifi chip compared to actually turned on wifi (which is also more accurate by miles than 3g location, works indoors in clubs where there is no 3g or gps signal, and not as battery expensive as gps location).
Also, people use that option for many things, I for one use it in MANY Tasker tasks flawlessly, whether the alternative (wifi periodic toggle and polling) would rape my battery.
Wifi automatically Turned off. Built in feature?
I kept my wifi on, and the had not used it basically just left the device in the room and had run off.
When I retured, the wifi was on in the power control widget but the wifi signal indicator icon in the notifications bar was absent.
is this normal/intended?
My wifi / internet connection is weak but continuous and my device is about ten to twelve feet away from the modem / router.
Can anybody help?
Although I have not a Nexus 5, my problem seems to be the same. I'll tell you if perhaps serve as any indication.
In my HTC EVO 3D, I've been running since the summer with CM10.2 (Android v4.3.1) with location mode set to "Network & WiFi" and "WiFi Always Scan ON". During this time the location was very accurate, location history left a fairly detailed trace. In Google Maps, was located immediately, as in Google+. If activated the GPS, even better. Summarizing, 0 issues with the location.
On January 1, I decided to upgrade to CM11 (Android v4.4.2), I set my location mode to "Battery Saving" & "Wifi Scan Always ON". During the first 10 days everything was perfect, the location history trail was so detailed as CM10.2 and battery consumption a little better. Google Maps and Google+ also positioned themselves almost immediately. Suddenly, on January 11 the location seems to stop of using WiFi networks and began guided only by the Network Cells (being rather more vague). Also when for some reason failed to position (being out of range of Network Cell), the phone started to not enter Deep Sleep Mode and the battery started to discharge at high speed. Google Maps, Google+, 1Weather ... were unable to obtain the current location or showed the last known location of hours before. Rebooting the phone sometimes temporarily solved the problem, but sometimes not.
I tried to change the placement options; abroad, with "high accuracy" mode, the location worked well, but indoors the GPS was not able to find satellites (logical) and still the same problems. I enabled and I disabled the location, nothing. Factory reset, no change.
To rule out a hardware failure, I returned CM10.2. Everything about the location worked smoothly... Return to CM11, again the same problems.
In short, my impression is that this is a software bug, as in versions prior to v4.4 Android location "Network & WiFi" + "Scan Always ON WiFi" works correctly. Moreover, not only occurs in the Nexus 5.
I have marked with a star your ticket.
I'll keept testing.
I get this problem when I use tether with WiFi always scan enabled.
When I disabled tethering, I have to manually enable WiFi to fix the location reporting issue.
With WiFi scanning not enabled, I do not get this problem

I think I have similar problem and I really hope smbody can help me.
On my stock nexus 5(4.4.2) wifi location don't work in google maps and ingress, when I turn it on instead of gps location.
But in other apps wifi location works( yandex.maps, 4square)
Only reboot helps
Hello again.
I just updated Google Maps to version 7.6.0 and Google Play Services to version 4.2.39 and all the problems I had with the location are gone, everything is okay again, as it did in CM10.2. So it looks like it is confirmed that it was a software bug.
Sorry, I know this post is quite stale, but I came across it doing a search about this very same problem I've seen on my LG G4 (stock). I have a Tasker task that uses WiFi near state and I use the "Allow Wifi scanning..." option in my Advanced WiFi settings. Whenever I would use WiFi tethering and then later turn it off, I noticed my Tasker task would not detect the WiFi networks it was supposed to. If I turn the "Allow scanning" option of and back on, or just turn on WiFi altogether, it starts working again.
So, after more than a year and a half, and on a newer version of Android and it still doesn't work right. Who knows; maybe it's a Tasker problem.

Hi guys,
Just a quick question.
Under Location, I notice that there are three options for Location Mode:
- Device Only
- Battery Saving Mode: which uses Wi-Fi.
- High Accuracy Mode: which uses Wi-Fi and GPS.
Excluding High Accuracy mode, which mode uses more battery: Device Only or Battery Saving mode?
Thanks,
device only = gps only. so that would use more than wifi. honestly i would just keep it high accuracy, but turn on/off location when you're not using it.
I havet just GPS on always and thats no need to turn location on off . As long you dont use any app that demand location the GPS is off and doesnt use any battery.

Use device only. Here's why :
Google Services such as Gmail, Now, Maps, and Google+ constantly polls your location using your wifi (if you're connected) or your cell network. And every time Google Services poll your location, your battery gets affected. So what's the solution to that?
Solution
Further research by Galaxo60 proved that going to Settings - Location Settings (or Location on android 4.4), and unticking WiFi & mobile network location (or setting the Mode to Device Only) prevents Google Services from polling your location, thus preventing the battery drain
So disable the WiFi & mobile network location option, and actually tick and turn on GPS satellites. (It's just like setting the Mode to Device only on KitKat)
But why do that? Why should by I turn on GPS?
Explanation
Google Services don't use your GPS to poll your location, so your GPS actually stays offline most of the time; and the reason you should enable GPS is to "Let apps that have asked your permission use your location information".
