Hey all,
I'm on vacation and Google navigation tracked me all the way to my destination like a boss.
Now that I'm here, my GPS thinks I'm in my home city, and won't move... I opened up GPS test and I'm only connected to 2 satellites.
My phone seems to get a decent location fix.
I'm wifi tethering to my TF.
Any idea what's going on?
Same issue. GPS icon appears but doesn't blink and just stalls.
Gps test - clear agps - update agps. Fixed the issue for me.

GPS location comes from several sources.( see your settings). One source is GPS, however if the fix is not great as when you just turn on TF and in a mew location, it will use the WiFi router location which is actually a lookup online that is set once and fixed. If the WiFi location for your phone was established and recorded at the online site while at home ( most likely the case) then the TF will read that and think it is home. Go to settings and turn off use wifi location.

+1 granted the wifi location is faster but if that router is registered to somewhere else (if you just moved or bought a used router online) then it'll say your there and tale a lot longer to get a lock.

If your wifi router location is wrong due to the situations mentioned above, you can have it reset by contacting "skyhookwireless".
No-go. Clearing the AGPS made the icon for GPS totally disappear, and refuse to appear again until a hard reboot. Even then it still just stalls. Trying a rom different from Prime to see if that might be the cause.
Has ANYONE else had issues like this? The GPS worked for a while but now totally fails.
I'm having some issues with the location google maps gives me. Even though I connect to my wifi it still shows I'm somewhere located in sacramento I'm using the custom made app with the destination features added on Anyone else having the same problems?

me too have this problem, says im somewhere in taiwan or whereever...but i use locations and only GPS without wifi...
I had the same problem months ago...
How to fix:
1 - http://www.google.com/support/mobile/bin/answer.py?answer=146524
2 - When you are arriving home, before the android connect to your wifi network, open google maps and let if find the location using GPS, then with the maps opened, go to the wifi range area. After 1 or 2 weeks it should fix your wifi location.
Try these 2 options, not only 1 or 2
Google has a database with the Router mac addresses and the location coordinates. This database is constantly updated.
This is driving me insane!
When I have WiFi enabled at the office, my Samsung Galaxy Note (stock ICS, rooted) constantly receives incoming data and I haven't got a clue which setting, app or service is causing this.
SystemPanel registers a nonstop stream of incoming traffic at 8 to 10 Kbps.
TrafficStats shows an accumulation of Received data under Total WiFi, but can't seem to link it a particular app or service: after resetting the data, no processes appear but the incoming data keeps on growing.
All sync options are off, I've tried to kill every running app or service (one by one, all at once), I've tried to block all traffic using Droidwall. As soon as WiFi is enabled, the incoming stream is unstoppable. When switching to 3G, there's no incoming traffic.
But to make matters even more mysterious, I do not have this problem with my WiFi connection at home.
It only occurs at the office, only on WiFi and (as far as I know) only on my phone.
Any ideas?
This is simply because your wifi antenna still "hears" the data going trough the wireless network on wich you are connecter. Event if your phone doesn't asks for any data at the moment the traffic there is on the network will still be counted by the wifi chip on your phone.
It will be the same on any public network or if you have another phone or a computer connecter on the same wireless router and generating traffic.
Thanks for replying, John!
That sounds very plausible, but then I still have to figure out why only my phone is registering this traffic - maybe it's an ICS thing or brand specific?
And I'll try to 'reproduce' it at home by connecting a laptop at the same time.
I think that the above is correct. That may be default behavior.

Well, I've tried to connect several devices at once on my home WiFi network, but it did not reproduce the incoming traffic problem I experience at work.
There were a few incoming bytes registered, not nearly as much as the constant stream of 10 Kbps at the office network...
Your works wifi may be set up like that. Who Knows?

Well, our it-department certainly does not.
You're probably right that this is normal behavior. I'll just have to figure out which drains less battery under these circumstances, WiFi or 3G. Thanks anyway for replying.
I'm on the mobile app, but if you have GSM then just switch to 2g until you use it.

About this, it is simply that at your office there is traffic on the network (download/upload) while at home simply having devices connected doesn't generate traffic or almost none. Start several dl on several devices (phone laptop) (guess 2-3 is enough, maybe even one but not sure, not en expert after all ) then you should notice signifficant traffic on your phone, I guess!
So interesting I find this thread because I have the exact same problem!!!!
How I noticed it...when I am at home I drop 1% battery on Wifi per hour. 10hours = 10% (sometimes less).
I go to work on the Wifi, I DONT USE ANYTHING ON THE PHONE and the battery is DRAINING LIKE CRAZY!!! 5%/h or more!!!
( I am in airplane mode in both place)
So I was thinking, WTF with this work wifi, i am not doing anything at all on it. Then I look at my wifi icon I have a constant RECEIVE icon. And I bet my phone does not go to sleep or something.
So why in the world my work wifi is draining my battery and the one at home is not. I will check tonight but I dont think I have traffic like this. I am registering 5-6kbytes/s for nothing. The explanation given above is hands-waving. I do not agree with it fully. YEs sure there are several pings and beacon emitted back and forth but i do not think it is enough to cause 5-6kbytes/sec . The wifi is not in Monitor mode and it only receives the packets destined to my phone.
This is madness!!!! BTW When I had a different kernel on back on ICS this behavior stopped. I will try to monitor again.

Hey kalinusa, did you find a solution to this problem?
I'm currently on the SpeedMod kernel, but that does not seem to make a difference to the 'office WiFi behavior' (so I keep my phone on mobile data).
I don't want to speak out of my ass, because I haven't a clue how the app works.
As far as I can guess SSH tunnel may help you. I would hope someone else could tell me I'm right, but I'm probably wrong.
I have had this same problem with two of my devices. The first is a Samsung Captivate with the last AOKP ICS build. The second is a Google Nexus 7 with AOKP's first Jelly Bean build (it happened when I had stock as well).
This only happens when I'm connected to WiFi at my university. The down arrow on the WiFi icon is ALWAYS on and it drains the battery. At home, I don't have these problems.
I emailed my university's IT department but I'm not sure if there's anything they can do. Anyone have any suggestions? Thanks.
I have exactly the same problem, but I think I found the reason which is causing it. I think that some of the routers are capable of the multicast over the wifi and then we can get a constant wifi traffic. I tested it at home, where I have enabled multicast over wifi and my phone wifi receiving the data all the time, even if it is in sleep. Now I'm in the office where we do not have such capable router with multicast over wifi and my phone wifi behavior is as expected. When I will be at home I will test it again with my router and with disabled multicast over wifi and hopefully it will solve this issue.

More than multicasts it could be broadcasts, what are you reaceiving. For example if you don't use WINS server in Windows domain, all computers use broadcast to get IP address for a computer name (if you dont use DNS name, but that's another story). At home, where aren't many computers, there are very few broadcasts. But somewhere, where a large amount of computers is on the same network (not splitted to broadcast domais), number of broadcasts would dramatically increase
btw. if you connect a PC to the same network as your phone and stop ALL running applications (mainly instant messangers, web browsers, e-mail clients) you should see the same network bandwidth in use as on your cell phone.

Interesting. Roughly how many devices would need to be on the same network, to see that kind of traffic load?

It depends on what you consier as network load. If you start a network monitor like Wireshark or MS Network monitor and even if there is one computer on the network, you wil see "some" traffic (from time to time a few network packets). To generate constant network load, you'll need a few dozens of computers. And it always depends on how the network is designed and what applications the computers run. If all computers connect to a server, the network load will be a lot lower than if the computers share resources among them.
Or you can design your network in such way, that you divide computers into segments, where computers can communicate only with computers in its segment (or with some distant servers). This way the network load will dramatically decrease, as computers from different segments would not interfere.
I currently only have one computer connected to my home network atm via wifi, and it keeps a constant broadcast going to my phone for some unknown reason. I thought it was my dlna server, so I shut that off, and it is still broadcasting _something_... Its causing quite a battery drain, and unfortunately I cant seem to find the root of the issue. I've trolled through my router settings -- multicasting isnt on -- so Im at a loss. =\

It can be caused also with the Media servers which runs on PC, also DHCP etc. It is not easy to eliminate all broadcast traffic and sadly our phones react at all that multicast packets.
I would think the GPS and a network connection would be good enough to triangulate where you are. I'm tired of the nag screen. I tried to Google for an answer but didn't find anything that exactly answered my question. Maybe when Google mapped out street view, they were also sniffing for Wi-Fi access points, and their names with locations? Just a theory.
Mine will work with Wireless off. Just tried it. Location settings to just GPS, Wifi turned off, map worked perfectly. Didn't try to navigate, but it should be the same.
Mine works fine without WiFi. It asked me once and I skipped it and it hasn't showed again.
Maybe because each WiFi router has the ability to send its location. If you were in a building without GPS signal you could still have location.

Yeah I know you can skip it, but if the program senses you're on a mobile network, and the GPS is on, I don't know why it still wants to have Wi-Fi on.
Just did a test with a couple mapping apps. If I am in an airport or mall without WiFi on it can't tell which store or gate I am at. With the WiFi on it can tell exactly what store or gate I am near. Maybe they use WiFi to pinpoint. Oh and I did have GPS on at all times but without the added WiFi location it was either not good enough signal or no GPS signal... Who knows maybe they are just watching us.

I think it's just that WiFi will always be more exact than data. You're accessing the Interwebz through one point rather than through your carrier.
Yeah but you're not connected to anything on Wi-Fi, it just has to be on.
There's a database of found access points out there. Your phone can triangulate its position far more accurately if it uses the available wifi access points to do so, especially indoors. Like oscar said, it doesn't need to be connected to wifi. It only needs wifi activated in order to "see" what access points are nearby.

The other day I came across a new option in the connections settings menu called "Mobile Data Only Apps". And it says the apps you select will ALWAYS use Mobile Data, even when connected to WiFi.
This is something that has never existed in android before and is an absolute godsend because I have been trying to get something like this to work on my phone's over the years, with no good solution. My work WiFi restricts VOIP calls so apps features like WhatsApp and signal calls do not function while I am at work.
The only problem for me is that it does not seem to work as I am still unable to get these VOIP calls to function consistently when I am at work. I have enabled mobile data always on in developer mode, but the VoIP calls still don't work. Has anyone else had success with this.
Interesting, will try to set some apps to see how it works...

It actually now works consistently, however, it requires both wifi and data connections to be rock solid. When I'm on LTE and the Wifi is strong, I am able to receive WhatsApp and signal calls without issue (work WiFi restricts access to both VoIP calls). However when the connection drops from LTE, the dual connection doesn't work so well.
Good job Samsung.

Only if you can find a way to restrict certain services on your router. If you know the ports used by certain apps like VoIP, you could block those on your wifi router and then have the apps use mobile data only.
I am really excited about this since Android never allowed simultaneous network connectivity in the past. I don't know if this is a Samsung only feature but it's great.

LimeyBastard,
I just figured out a much better way of testing the feature without touching your router.
1. While connected to your home WiFi, Open up a browser app (I prefer Firefox focus since it's in incognito mode by default), go to one of those IP address checking sites like whatismyip.com and take note of the IP address.
2. After this go to settings and allow the browser app to access mobile data only.
3. Without disconnecting from the wifi network, close the browser app and reopen it and then check your IP address. It should be different from the initial IP you got under WiFi (it should show you the IP of your cell network provider.)
I checked my wife's Note 8 and this feature isn't present, so it appears it's an S10 only feature for now, but I could be wrong.

I have attached mine as well. Is your cellular data ISP different from your home internet provider? Also did you refresh the browser (I force stop it and then reopen before checking the IP). Also ensure the browser is one of the apps listed as using mobile data on the persistent notification.

Yes, my cell service T Mobile and my home wifi is charter comms.
Edit . So I just reinstalled firefox then before launching it I changed the setting for it to use mobile data only. And it seems to work. Weird.
