Case: If I download maps for my city.
Then turn off WIFI and data connection. Just Keep ON GPS.
NOW what things can I do with downloaded maps???
Q1. Can I search for places in my city? (Offline)
Q2. Can I search for directions to a destination from my Location (using GPS) without any data or WIFI.???
I mean the downloaded maps contains streets and places and landmarks also. So Can I get directions WITHOUT any data / WIFI connection??
Q3. Say I search a location and also get direction to that location in OFFLINE mode, (((((assuming answer to above 2 questions as YES)))
So can Nokia maps guide me with NAVIGATION to that location WITHOUT any data / WIFI connection??? Just by using GPS...
Yes, yes and yes. Just tested it now.

Wow, I tried searching it on YouTube, but there aren't any videos for this.
Maybe I’m just being impatient, but I’ve never managed to get a GPS fix without any sort of data connection. Can anyone confirm this is possible, if so how long did it take to get the fix?

Yes, with a data connection, you can dramatically shorten the GPS fix time. Without it, it may take many minutes from a cold start and still a minute or two from a warm start (means you had a fix before on the same location short time ago). With data connection to assit, you can get a fix as short as less than 10 seconds.
AGPS is a quick way to get a GPS lock by downloading ephemeris data.
Without a data connection the GPS chipset will manually discover the positions of the satellites which can take up to 5 minutes. The longer the time between each use of GPS the longer it takes to get a lock. So the first lock may take a few minutes but another lock on attempt on the same day may take 10 seconds.
I have used so far the GPS without Data(phone is locked no sim) in a few countries now. Mexico, USA, Canada and China. So far I had only one issue in Canada as I never had a wifi before going to car rental at airport. The GPS didn't link up for a long time. If you can hook up to wifi before leaving airport and turning Nokia Maps or navigation on to learn GPS positon may help out the time. There is sometimes a small lag in China for position but normally working ok and acuracy seems to be within reason. Funny issue though it sometime always takes me back to Mexico, like it is stuck in memory even after weeks abroad until GPS position is located.

With data - fix in seconds, even indoors - that's because the system will get an idea of where you are based on the location of the cell tower or failing that using wifi to get a location. This inaccurate location is good enough to narrow down the possible locations of two or more GPS satellites, so the system can more quickly triangulate your position on the earth.
Without data - standard "search sky for fix" cold start time for GPS - with a clear view of wide area of sky, 5 minutes to find three sats, figure out which hemisphere you are in, and then fix your position. If you are standing still. With obscured sky or you moving reasonably fast, 2-3x longer. Indoors (or in a car), forget it.
http://www.pocketgpsworld.com/howgpsworks.php
Real world - on a cruise ship in the pacific making 20 knots or so, I was not able to get a fix from the balcony of my room, ever (not enough sky) but on top with clear 360 degree view of sky it did fix after 10 minutes. When in port in Mexico (not moving) on deck, 5 minutes, or instant fix when roaming on one of the Mexican cell towers.
5 minutes? that is very long, probably has to do with the location. with deactivated data/wifi cold start gps fix takes me 10s, accurate location (<5m) after 30s (cloudy, indoor but next to a window)
Question ...
Are you satisfies with the number of locations Nokia Maps knows in your country??
In India, in my city, it does not know names of places not even 60% of Google maps.
I'm talking about places and NOT about names of streets and squares . It knows names of many streets & squares(still less than Google maps)..
I'm asking about places and bussiness places. New places.
Also, for any restaurant, the number of reviews Are. FAR FAR less than the number of reviews of that same restaurant available on GOOGLE maps.
This is about Nokia Maps in my city (very famous) in India.
Please tell about your city/country so It'll help me and all whether they'll need Google maps ( gMaps )app to Download or not.
recommend have gmaps as well. It has more detail. No app is perfect, Nokia doesn't have as much details for locations.

I went to Nokia Map Maker and there I located my college and some other places in my city and then I added them to Nokia Maps.
But then after a month also, when I search for my college using Nokia Here maps, it doesn't show it,even though I added them 1 month ago.

Hey guys.
Having a weird issue with my Legend. I went cycling the other day and wanted to use one of the GPS tracking programs available.
I download:
Google My Tracks
Runkeeper
CardioTrainer
None of these programs worked. I was outside in wide open spaces the whole time so should of had excellent GPS reception. The little GPS symbol was in the status bar but whenever i hit record on one of the programs it never tracked my distance properly. 99% of the time it didnt record anything although i had cycled over 30kms ha. One time CardioTrainer did record my distance but it was incorrect, it was recording way too much...like 5km in 2 minutes.
I gave them plenty of time to get a GPS fix and also turned on the internet so it could use AGPS but the same thing...
Anyone have any idea?
EDIT: Crap wrong section, sorry guys.
Is there a navigation app that will work while "not" connected to a mobile network?
The built in one will work for a little bit and then stop with "Data connection lost"
It's just because it is streaming the data constantly. If google could pre-cache the data then it might work. I ran into this issue on a long trip where I went through an "Emergency calls only" zone.
You just need a GPS app which uses offline maps.
Search for them on https://market.android.com
You should expect to pay something for them - basically, you are buying the map content.
I haven't used any of them, so I can't give a good recommendation; they are available, though.
Note that the Eris uses QualComm's "gpsOne" series of GPS chips, which uses A-GPS (Assisted GPS). The assistance data comes from the mobile network, and pre-seeds the GPS unit with an approximate location, which helps in finding a "first fix" rapidly.
What that means in use is that if you start up the phone from a cold start in a location which is outside of cell coverage - and also a fair distance from the last location where the GPS unit got a fix, it might take as much as 60-120 seconds to achieve a first fix. Thereafter, it should be able to update fixes rapidly.
I have used the Eris while driving distances of 40-50 miles in mountainous regions without cell service (using the "My Tracks" application), and it had no problems figuring out where it was (Lat/Lon) at all times, but of course it did not have any "map" data for me to view - I was operating the phone in Airplane Mode to preserve battery. I have also used it to "mark" locations of interest after camping overnight and fishing in areas that were completely void of cell service. In those cases, I was literally powering up the phone, gettting a GPS fix (might take 1-2 minutes), recording the Lat/Lot to a notepad app, and then shutting off the phone. Worked perfectly for that, but I was only getting Lat/Lon in that case.
Make sure you operate the phone in Airplane Mode - the battery will drain quite quickly if you don't do that, as the phone is constantly scanning (at full power) to try and connect to a voice (1x RTT) network.
What I have not done, though, is spent many consecutive days in the wild with no service... so I am not entirely sure what would happen if the A-GPS data got too "old" and expired. The QualComm docs suggest that the gpsOne chips should be able to operate fully autonomously, but whether that happens depends on the software. There were reports way back when the Eris was still on Cupcake (1.5) that folks that traveled outside the US could not get their GPS to work correctly.

I have a lot of experience with trying a few of the commercial (pay) Android GPS apps. Firstly, due to research, I found that there was, at the time at least, only a very small handful of commercial GPS apps which supported MDPI (the Eris' screen resolution). Shame because otherwise some of the ones which I can't remember by name sounded very promising.
There were definitely two which did work on the Eris. Like anything else, each one had it's own advantages and disadvantages. I thoroughly tested CoPilot Live for Android v8. It wasn't bad, and I see now on their main page advertising $5 for U.S. and $19.99 for all of North America (U.S. and Canada), which seems almost too good to be true, but I verified it on the Android Market. I don't remember having any particular problems with CoPilot, I just preferred iGo My Way 2009, but their website no longer even mentions the Android except for here and I don't see it on the Market.
That's too bad but I guess that helps you to make a decision on buying one if you do so.
Maybe it has something to do with how much iGo got pirated, as alluded to in this thread.
I did buy and am currently using iGo My Way, except when it's just a shorter trip, since especially on the Eris, there is a definite slow initial load time for the app (under a minute but slow in our impatient world). Once the app's loaded, however, it's lightning fast. Definitely recognizes wrong turns a lot quicker than Google Maps.
Another vote for iGo MyWay. Starts up in about 45 seconds, but it works perfect in landscape and portrait. Once its loaded its the fastest turn by turn I've ever used. (I've only used older model "JUST" gps devices though. FWIW)
apparently there is a modified version of google maps that allows cache of data. I have nothing to do with this program and have not personally used it. i am just reposting here:
*edit: removed old link see other forum link*
apparently you can load it in addition to regular google maps and have both of them on your phone.
"You can enable map caching (Menu -> More -> Brut Mod -> Read map from cache, Save map to cache). This will force GMaps to save map tiles to the SD card and read from the SD card first, before attempting to download from the net. You can connect via WiFi (or any other net source) and preload the tiles before you start your trip, thus making the maps available for offline use.
The preloading can be done by simply browsing the the route you will be travelling - just make sure you do it at the zoom level(s) you desire. I believe you can even use programs like GMapMaker to download the map tiles from a regular computer, but I haven't tested this method."
edit: found the post on xda http://forum.xda-developers.com/showthread.php?t=630887
edit 2: also enables use of google maps in other countries
starting p235, there is a discussion of some ownhere version that uses gmaps5.1. i believe it still allows downloading of maps to cache.
Hello,
Like some of the other users, I had GPS problems after installing these two ROMs: connecting to the satellites took a very long time, if at all. Below I describe my fix, gathered from searching on the web, including here on XDA, and by using trial-and-error testing. Hope it helps others.
Install GPS Test by Chartcross. This helps monitor the GPS activities. There are other similar apps out there, but I like this one for the purpose of monitoring the GPS.
Install FasterGPS, by Dominik Schürmann. This is to edit the file /system/etc/gps.conf. You could edit it manually, but I like the GUI of this app.
Check if your /system/etc/suplcert/cacert.txt is "MIIDazCC......neEj8Nq/", then under the advanced settings, make sure SUPL_HOST is "supl.sonyericsson.com", SUPL_PORT=7275. Each cacert corresponds to a particular SUPL server. The above cacert is for the Sony server. If the host doesn't correspond to the cert, then you will not benefit from a quick retrieval of GPS info via the internet. Instead your GPS will download the info from the satellites themselves at a very slow rate (50 b/s according to Wikipedia). Your GPS would still work, but it won't acquire a fix quickly. Sorry I don't know what the cert for Google is.
Set NTP server to something close to you. Some people suggest to enter several servers (more can't hurt), some people suggest not to do that (more does hurt, if the previous ones fail.) I imagine that, at the higher level, the ntp pool servers don't usually fail. Thus I choose a single server that is close to me. In addition, I stay at the "country" level instead of going down to the numerical prefix level. (I.e. I don't bother with 0.uk.pool.ntp.org.) I figure going down to the numerical prefix level would more likely expose me to server failures.
Set INTERMEDIATE_POS=1 (enabled), then set ACCURACY_THRES=0 (passing all positions). With this value GPS Test usually reports satellites "in view" very quickly [<= 1 sec]. [Note: "in view" not "fix".] When I set the threshold to something non-zero (even a large value like 5000), it takes several seconds to see them.
Set ENABLE_WIPER=1, which supposedly turns on wifi positioning. Not sure what that does, but sounds like it can help . I assume the GPS system reads info from the wifi to get a rough estimate position. GPS Test probably isn't affected by this, although something like Maps might.
Set REPORT_POSITION_USE_SUPL_...=1. Again this sounds like a useful thing. My trial-and-error testing didn't discover anything conclusive about this. If anyone know more, please let me know.
Set DEFAULT_AGPS_ENABLE=TRUE, DEFAULT_USER_PLANE=TRUE. These are probably already true by default, but I figure it doesn't hurt to be explicit.
Reboot your phone if you had to change the SUPL setting. I had to do this to see the change. Would love to hear your experience on this.
With the above settings, GPS Test usually reports about 10 satellites in view in about 1 sec; satellites signals popping up above 10 db in about 5 sec, and the GPS acquiring a fix with about 4 satellites in less than 30 sec. All this _inside_ my house, which is a timber frame house with tile roof. I get this even with airplane mode on, i.e. no network connection!
If I use GPS Test to download AGPS data first, then the fix could be even faster, at less than 15 sec. And once the GPS has acquired a fix then, within a short time span, it will do so again very quickly (< 5 sec). Thus I have no problem as I switch from app to app and the GPS sensor turns on and off.
If my AGPS data is several days old, I still can get a fix in about 1 min.
Still, sometimes no matter what I do, the GPS would take more than 1 min to acquire a fix. Not sure why this happens, but it usually occurs after I haven't used the GPS in a while. In those cases I might have to wait up to 5 min for a fix.
Notes:
I assume you have root (since you managed to install ROMs )
According to the official ntp pool website,
As pool.ntp.org will assign you timeservers from all over the world, time quality will not be ideal. You get a bit better result if you use the continental zones (For example europe, north-america, oceania or asia.pool.ntp.org), and even better time if you use the country zone (like ch.pool.ntp.org in Switzerland)

More about my choice of accuracy threshold: if a threshold is active, it seems like the GPS would wait for the signal of a satellite to be of a certain strength before reporting it as in view. I figure it is better to just grab all the satellites possible, even if there is no signal yet.
The app GPS Status & Toolbox, by MobiWIA - EclipSim is also a very useful monitoring tool. I like the feature that reports how "stale" the AGPS data is. Wish GPS Test had this as well.
Toggling on the GPS from the settings menu simply allows apps to turn on the GPS. This doesn't use any battery. Only when an app starts using the sensor does it take energy. I recommend having this on. Having said that, do make sure you don't have any rogue app keeping your GPS engaged.
Install NTPSync, by Dominik Schürmann again. This helps set your clock. Not sure if this is necessary, but it gives me a good feeling that my clock is accurate

I assume you had GPS working at some point prior to installing the ROM? If you've done all the steps (particularly steps 3, 5, and very importantly 9), then I'm afraid I'm out of suggestions.
spelling?
On the off chance... perhaps you have a spelling error?
I find it quite easy to spell "sonyericsson" wrong, especially the ericsson part. Now I have a way to memorize it: "Eric" (that's easy), "Eric's" (as in something belonging to Eric), ericsson = "Eric's son"
I've noticed using Waze I'll see GPS go in and out, and occasionally I try to post pictures to Instagram and find out there's no GPS tagging in them. Anyone else seen this?

YES! Install a GPS Test and you can actually see the amount of Satellites seen go to zero. I can sit in the same place for 5 minutes and it will go from 21 to 0 every 10 - 60 seconds with a clear sky. I am wondering if this is a software or hardware issue. It is noticeable when using Gmaps to navigate, you will see your arrow simply stop when driving down the highway for 5 seconds at a time.

Sometimes indoors GPS has more difficulty. Has it worked there before with other phones?
EDIT:
Worked with my GPS navigation a bit more... definitely see the GPS lose tracking every few minutes. Turned off the iZat, didn't make a difference. Plugged in a power source, thought it might help a little, but nope, GPS lost every once in a while. Bah, just when I thought I had received a problem-free unit
Any more information on this? As of April 1st, my LG G5 seems to be way off on GPS. I noticed it using Runkeeper. I thought maybe it was a Runkeeper issue, but then used MapMyRun and got the same I looked in history and saw that since getting this phone (traded in my G4 for the G5) I had one successfully tracked run, then it all went haywire. Never had a problem with the G4 - so it can't be signal issues (IMO). And since this phone got it right once... that is strange to me.
To give an idea... I ran about 10 miles and it told me 18. When I looked at the runkeeper map it looked like I was running down side streets, into fields, crazy stuff. Like it never got a real lock on my location.
I'm wondering if I need to return this phone??

I have only used the G5 in the car a few times and it seems to work fine - using google maps, not waze.
I use a couple apps to track biking and they work fine. However, when I use them I use an app called GPS keeper pro to keep the GPS running all the time. It seems to help with apps for fitness. I started using it with the G3 and just kept right on with the G5. You might want to try GPS Keeper for your running apps.
I use GPS only in the location settings. That may help. At least my apps that rely on GPS open much faster with that setting.

My specific GPS issue was that it would lose lock a minute or so into a perfectly normal navigation lock while using Gmaps. It would relock after several seconds, only to lose lock again. This repeated over and over.
I was using the app GPS Status to monitor this. However, it hasn't surfaced in a few days, so I don't know if there was some rogue app or former setting that was interfering with GPS holding lock. I've hypothesized maybe it was GPS Status itself which was interfering. I uninstalled and reinstalled it, and so far *knock on wood* it hasn't popped up again.
This sounds a bit different from some of the problems listed here. The run tracker not getting a good track might be related to this, if it is never able to consistently keep GPS lock. Try monitoring the GPS satellite lock icon when the app is running. Does it go from lock (white) to not lock (grey)?
Mine is actually grey most of the time but when I'm connected to wifi calling it's constantly white. Weird. This thing needs an update for a few different reasons. Coming from the note 4 I notice differences in the software obviously but somethings seem like they don't quite work right. Example being when I used wifi calling on the note 4 it would grey out the regular signal but on this it's still active with the bars going up and down. I'm pretty sure it should cancel the network out all together but maybe this is just different. I don't know.

Maybe it's using the wifi connection hotspot to determine your location? So does your GPS really work at all then?

Well I do have it set to GPS only in location settings but until I get out and try to use maps I guess I really won't know. It does find me in maps or other weather apps though.

Well - I got my second LG G5 hoping that would solve the problem. Doesn't seem to be any different
I've tried this so far:
High Accuracy - Was Already Set
Turn off WiFi location
Tried GPS Keeper to keep signal alive
Tried GPS Status Utility - NOTED: Takes a long time to lock and still will start 'searching' for long periods of time.
Tried with no cover on
New phone seems the same I love the LG phone itself, but I can't handle this. I should have returned it for a Samsung. Are there any other tricks I am missing?

Do you perhaps have greenify on? I have a theory that the aggressive doze may be affecting GPS lock duration.

Correct, you don't have it installed then. Have you tried disabling iZat? It's the low power GPS addition, at the bottom of the GPS settings page.
Also, just to cover all the bases, you are outdoors when you're searching for GPS, right?
I have a stock T-Mobile G5, I've also noticed inconsistent GPS. Acts as if it's stuck. I'll open Google Maps and it'll show my location from 90 minutes ago. Won't update until I turn on airplane and then off again. Once the radios come back up GPS updates. Hoping for an update to fix this ASAP.

The low power GPS is turned off, yes. When I run the test I am running it right next to my window indoors. I run it on my HTC One (not activated) and my LG G5 (activated - new phone). HTC locks immediately (2-5 seconds) with 14/20 satellites, G5 does not lock for at least 3 minutse with anywhere between 18-26 satellites (I gave up after 3 minutes). I tried turning off/on airplane mode like the previous post - didn't change anything for me.
Even though the GPS doesn't show lock on the LG G5, I can get google maps working. It isn't very accurate, though. It sometimes shows me stuck in a location for about 1-2 miles. It also shows me off the roads, typically.
I found a way to replicate the GPS issue! I was having it behaving really intermittently on my car mount (vertically), and then I decided to tilt it horizontal and suddenly it got a lock! I've verified it by GPS test apps and it's super obvious that in a vertical orientation, the GPS doesn't get a proper lock.
Any of you guys wanna validate this?
I'm having this issue as well, sometimes takes a couple minutes or more to obtain initial lock when I get in my car every morning and start Waze (although it guesstimates my location based on last lock / WiFi), plus then it drops out 2-3 times per drive, which is incredibly frustrating and has caused me to miss turns. I lose lock with WiFi both enabled and disabled during my drive
As a couple people already said, I use the T-Mobile G5. I'm curious if all of us experiencing the problem use the T-Mobile version and it might be a carrier ROM issue. My network and GPS settings are how they were out of the box, although now that I know it exists, I'll try disabling IZat low-power location just to see if there's any improvement.

I found a way to replicate the GPS issue! I was having it behaving really intermittently on my car mount (vertically), and then I decided to tilt it horizontal and suddenly it got a lock! I've verified it by GPS test apps and it's super obvious that in a vertical orientation, the GPS doesn't get a proper lock.

My phone is always horizontal in my car dock, with the top of the phone facing left, but I'm still losing GPS lock. Do you use yours horizontally the other way?
I can tilt mine any way I want and it won't lock I ran a test this morning while taking my kids to school. I took out my old HTC One and turned on Runkeeper (running app). Turned Runkeeper on LG G5 (separate Runkeeper account to be sure nothing got screwy). G5 couldn't lock enough to map anything, HTC mapped perfectly to the roads. I then used VZ Navigator (Verizons map system - this was done at Verizon's request). The maps trailed me by about 1/2 to 1/4 mile and showed me about 200 yards off the road. Then - GPS lost. All the while - HTC mapped me out with Runkeeper perfectly mapped to the roads.
Since this is my second LG G5 with GPS issues... I think there is a problem with the phone or maybe the Verizon version of the phone. Sounds like T-Mobile also, though, so could just be some LG software screwing things up.
Either way - I'm probably getting the S7 now. I really like the G5 with the rear fingerprint scanner... but I need a GPS that works out of the box.
Does anyone else have issues with their unit (I have the T-Mobile version) mistakenly showing their location as someplace they were HOURS earlier? My maps shows the location where I currently am, but then will occasionally report my location incorrectly as where I was earlier that day, which affects my weather and traffic reporting. Any thoughts?
Do you have high accuracy enabled?
I do have high accuracy enabled. Which the phone doesn't seem to understand the definition of.
If it is showing properly when you open maps but not in other apps, then it isn't the GPS that's the issue. Those apps aren't updating properly.
Mine is off by about 20 ft or so ... no biggie.
One thought though ... do you have background data blocked for the map app?
Background data enabled. I'll use the phone to navigate from work to school. The map shows me at school. Weather and traffic based around campus. Then, maybe an hour later, I look at my phone and it gives me the weather for my office, not school. I open google maps, it looks like I'm back at work, but I'm not.
I have had this happen several times. I open a gps Waze and Google maps, for a little while at work then minmize. A few hours later I will use the gps again at a different location and the gps will flip back an forth from the previous location, this will occur 30 min away or in another state.
I have tried to just shutdown the app and restart but still occurs. My only way to clear this has been to reboot the phone. This happen on both Waze and Google maps.
I found turning location off and back on works for me, but this shouldn't happen

I've had this issue several times. With my G6 and V30. It happens when I'm using a GPS heavy app and then go inside where a good GPS signal cannot be found or where I'm on WiFi. Oddly. I feel like it happens more if that iZat crap is active. Happens a lot with PoGo.
Also get heavy GPS drifting when in High Accuracy Mode. GPS on LG devices seems to work best in Device Only Mode.

This is driving me mad. I had to switch phone due to this issue on Galaxy S7 and now it happens on V30.
Took a factory reset for mine to work again. Was fine for the entire time I've had the phone, then out of the blue, just stopped working.

Chiming in with "other phones have wonky GPS too": My Moto X Pure has had a couple instances where position appeared to be randomly jumping around, up to several hundred feet away with varying azimuth. Made for " fun" navigation in heavy traffic in unfamiliar cities.
But don't worry, autonomous vehicles will work without a problem. (Yeahhhhh....right....)
...
Autonomous vehicles are using a wide array of sensors to work, combine with deep learning, big data, etc. The GPS used in phones is not the same chip as the one used in a dedicated GPS device, even something as a sports watch as a much more precise GPS, optimised antenna, dedicated processor and optimised OS. I’ve been trying to use phones to track my runs for years and it always jumped around a bit. In a car, depending on the placement (direct view of the sky, for instance vs. blocked by the ceiling), on the weather, on the insulation of the car even, you can have issue with jumping signal. You can try to place the phone in a spot where the antenna has a view of the sky and it might be less of a problem.
I have noticed that the issue is with both Pokemon Go and Google maps. It is really frustrating, and sometimes nothing seems to help. On another site, they recommended installing GPs Status and Toolbox from Google play store. I will try that. If that does not help, the site said that the issue is with the GPS antenna.
