GPS issues on stock Rom using Google maps - Xperia Tablet Z Q&A, Help & Troubleshooting

Hi I was wondering if anyone else has experienced problems with GPS and google maps attempting to locate current location? With both options under settings ≥ location services enabled for GPS and using my WiFi at home I am unable to retrieve my current location it just says your current location is temporarily unavailable, so though id see if anyone else has the same issue.
Im using 10.1.C.0.370 firmware.

Hey man, I have the WiFi version and I noticed that the stock Navigation app sometimes has problems finding my location compated to my Samsung phone. I was on the road last week traveling between France and Germany and on some occasions I had to use phone to get directions because the tablet would simply not get any GPS signal. On other occasion it would work. It seems to be pretty random. I'll post if I find more about this.

Hi thanks for the info, ive been messing around with it some more since i made this thread and this morning i was finally able to get a GPS signal and get google maps to zoom in on my current location but i had to go into settings > location services and disable Google's location service and turn off my wifi so it was just the GPS running. But after doing so i re-enabled the settings and turned WiFi back on and it worked fine lol.
maybe its just a bug in the software i don't know but your right it does seem spotty at the best of times.

[Q] Why GPS doesn't work without internet?

Hi,
I'm just wondering why my GPS doesn't work without internet connection. It just can't connect to any sattelite. I'm currently using PFGPS v2.0 FIX for my country (Poland) and I don't see any changes. What is wrong?
It requires Internet to load the maps
Can I load maps now to use GPS without internet connection if I'm not in wifi area?

how can you load maps without internet connection ??
I'm at home now so I can do it cause I have wifi here :/

so you have wifi that means you are connected to the internet!!!
for GPS it can only find your position but can't display your location on a map without an internet connection so GPS needs one.
I will wait for answer from another person. Thank you.
There is an application on the market(related to sports/tracking) that allows you to download a portion of a map and then you can use your GPS offline(no data connection). When I get home I will look for it(I have it on my tablet).
Correct me if I am wrong but Brajano95 means that is it possible to load the maps on his wifi connection and keep then saved when he is out and about to allow the gps to connect. You used to be able to do this in the google labs section on google maps but they've since taken it away unless you look for an older version. Otherwise have a look for third party map app on the android market which allows downloading of map data to the phone

Thats exactly what I'm talking about! Now I'm downloading Sygic Aura (about 550 mb) and will test it later.
Because GPS and Maps on CM7 suck balls at best. Maps is using your I.P. for the GPS coordinates when on WIFI, without it Maps is counting on a reliable signal from your GPS; and that's just not going to happen with CM7.

I know a fair bit about the GPS module in the Ace so i will comment. I think someone has already told you that it is possible to operate the Ace with preloaded maps. Likewise, i thought that the OP's choice of Sygic Navigation is a fair one.
Back to the original question in the title. GPS can operate with or without internet be it wifi or data e.g. 3G/2G. The difference is how fast you can obtain a GPS lock. Without using any positioning help from data connectivity, you are looking at a lock time of possibly 15 minutes thereabout.
There are 4 modes of operation possible for the GPS module in the Ace which is actually Qualcomm's GpsONE.
1.) Standalone (Slowest using positioning information in cache and smart polling)
2.) MS-Based (Sends data to nearby cell tower(s) and makes use of GPS transceivers in the cell tower(s)
3.) MS-Assisted (Similar to MS-Based BUT data connectivity is broken when GPS transceiver is online. I don't quite like that!)
4.) MS-Based/Hybrid (You need to have superb data connectivity probably cell tower signal strength should be in the -50dBm region. Not very useful in real life usage)
i have had my own thread for fixing GPS, so read up if you want to know more here.

first you need the maps to use it offline, and the correct gps.conf for your location http://forum.xda-developers.com/showthread.php?t=1284506, then you can use it without internet
Mapdroyd is a great app that allows you to download maps for offline use. Unfortunately there isn't offline navigation though..
Hi,
I've solved my problem, just install Sygic! Thanks for helping guys
btw u dont need too install anything.. go to google labs inside maps and add map cache.. now long press a location on map.. click the arrow on the address and u ll see an option to cache that area.. the steps may not be accurate as i tried it a long time back and dont have my phone with me but its possible and what u have to do will be more or less the same...

School me on the GPS and Google location services

So I've had my phone for a year and rarely use the GPS feature.
In the past (stock) I've kept all my phone features on including Google location services, etc. Now that my phone is rooted and running AOKP, I turn off all the Google location services, report my location, etc, to save on battery.
My question is since this phone uses A-GPS (yes I wiki'd it) does it mean that it is REQUIRED to have these location services turned on in everywhere in the phone in order for GPS to work? I've tried using GPS without all these services but for some reason GPS didn't seem to work. It comes back with can't determine location, etc.
So do I need all these Google services to be running or should I just be able to enable GPS and have it work for turn by turn navi?
Should only have to have GPS turned on.

AFAIK agps just helps it obtain a lock faster.
Sent from my SGH-I777 using xda app-developers app
aGPS supplies the GPS the updated almanac and ephemeris data from the network, and allows faster lock by aligning the system clock using one of the clock servers.
If it sounds like Chinese - then google all the unknown terms, and eventually you'll be able to google the answer to your question.
I read some other article that stated you needed to have data turned on as it draws the maps. All the google maps are not stored to the device???

No. You need data. And either Google's location service or gps turned on.

So what does "make available offline" in the maps settings do? I guess I just can't turn on GPS and enable "offline maps" mode and that will work too.
This is why I ask these questions. Some people say you don't need anything other than GPS and other say you need to have location services on.

When you enable offline maps it's only for a small area.

Enabling offline maps tells the device to cache any routes you plot in nav or maps so that if you lose data connection navigation will continue to function. If you depart from that route without data connection, you'll lose nav.

1. If you just want to use the GPS feature, then it must be TURNED ON. That's it. No other requirement, other apps asking for location services have nothing to do with GPS function of the phone.
2. About google maps and gps service on this phone.
a. the map itself is stored on their Google server, so in order to use map, you must have accessed internet, hence either wifi or mobil data required.
b. if you carry other maps that stored locally in the phone internal space such Tomtom, Sygic, .... you DO NOT need wifi or mobil data to use this function.
3. About the Google's OFFline maps. A lot of people do not fully understand the usage of it.
Back to step 2a above, I said "google maps stored on their server" so you need internet access. In this case, offline map is just a small cache (10 miles radius) and it does store in the phone memory. So yes, you do NOT need internet (wifi or mobil data) to use "offline maps" (of course, you must create one before hand)
What is the down side?
a. As mention, it is just a small cache.
b. If you define the term "GPS" as global position system then you know all it does is getting lock and determine your location and that's pretty much is. You CANNOT route the route. You CANNOT navigate from point A to point B. You CANNOT search for an address.

Phone Location Problem

Google location services reports that I am in Cisco Texas when I am really in California. It only happens when I am home and have wifi on. I've had the same problem with multiple ROMs from CM 9 to PACman (4.1). If I turn off wifi my location is reported correctly. I've changed my wifi ssid and deleted maps data but that didn't help.
I searched the web and found that others have had the same problem, often erroneously showing them to be in Cisco Texas when they are in diverse locations from Denmark to Oregon. Google's mobile help forum had a thread on the problem but it was closed without a solution due to inactivity.
It is hard to plan my day when I am getting weather data for a location 1500 miles away.
I've posted the problem to google's help forums, but I have more faith in you folks than in the people over there. Any ideas would be greatly appreciated.
Edit: My Touchpad running CM 9 or a CM 10 derivative at the same location does not have the same problem.
TBH, the only thing you can really do is give it time. Google location works by extrapolating your position from the WiFi you can see cross referenced to a face l database at Google. It doesn't know where you WiFi really is, so is putting it there. Eventually, it will figure out where it really is and update it, but that relies on running other location sources that or can check against. Run GPS a lot, especially when you coming and going and it'll figure it out.
When I moved from Montgomery to Atlanta, it took a few months for Google to update my WiFi location, but it eventually happened.

Android doesn't use Skyhook. It uses Google's location service. Skyhook maps things by driving around in vans that scan for AP's. Google relies on user devices to build their Wifi maps.

I registered the MAC of my Wi-Fi router with Skyhook back when I got my first iPad 2 Wi-Fi so it could be located. Now if I have both my GPS and mobile data off on my phone, my location is provided by Wi-Fi, exactly at my house. I know Skyhook worked for my iPad 2.
Also, I think that Google does the same thing by using your GPS and logging AP's locations you are on.
Either way, it wouldn't hurt to try if the location isn't working for you. Could be that somehow your GPS was wonky and reported your AP location incorrectly and it just hasn't been updated in Google's system.

GPS seems not to work

about a month a go I loaded a custom rom
[ROM][PORT][4.2.1][AOKP/CM] Vanilla RootBox v3.6 [31/01][Per-App-DPI][PIE]
since than when i go to google maps or navigation it says waiting for location and than after a few mins it says your current location is currently unavailble. when i check the location acccess option the wi-fi and mobile network location is disabled. when I enable it it does seem to find where i am but uses data to keep updateing. so I disabled it. I was wondering if anyone knew how to get the GPS opetion to work and find me so I can use the navigation again.
thanks.

Why can't I enable GPS without agreeing to some data downloads?

Just got my Z2 and I'm practicing in offline/unregistered mode because I plan to use the phone without Internet during a trip abroad. Got OsmAnd installed with maps etc.
Problem is, I can't enable GPS without agreeing to some data collection on me:
The device will download information about your current location to improve the performance

"The device"? Is this some SONY crap, or Google's Android? How will performance be improved?
How do I disable this if I don't want my location sent to some random server? If I Disagree, GPS stays disabled.

In the Location menu in settings, set Location mode to "Device only", you'll notice if you select "High Accuracy", not only does it say it'll use Wi-Fi and mobile networks to determine location, it'll also have the notice about data usage pop up, Device only means it will solely use GPS to determine location.
Probably to help get the initial fix for your position?

Imagine High Accuracy mode as A-GPS, using data networks to download GPS coordinates as well as getting your location from IP address location and network proximaty etc
Device only wont use any data networks or cellular information either, try it out anyway, take your sim card out and turn wifi off and go for a walk, see if it works.
It just downloads agps data which helps, making the gps fix much faster. Since this download may charge your service fee, you get the warning. Its nothing about Sony, every phone with gps does that.
