[Q] No GPS coordinates in photos - Galaxy S II Q&A, Help & Troubleshooting

No GPS coordinates in photos
Guys, I need your advice.
I am travelling with turned-off cellular data on my i9100 since I am abroad.
I am taking pictures - a lot of pictures. But I just found out that app. 90% of them do NOT have GPS coordinates.
I tried everything:
- checked settings
- restarted phones
- connected to WIFI
- installed GPS Config for rooted phones and set up the location
- flashed ROMs (AOSP, AOKP, MIUI, stock ROMs).
BUT nothing helped. I think that something is wrong with my phone.
Why? Because iPad Mini + iPhone 5 captured GPS coordinates IMMEDIATELY. I mean in 1 second!
The strangest thing is that Navigon gets GPS position really fast on i9100, but it cannot navigate me - it is waiting and connects after app 2 mins.
Thanks for help.

It looks like that stock-based ROM are better - if you wait app. 1 minute, it gets GPS data to your photo.
Good ROM is here: http://forum.xda-developers.com/showthread.php?t=2411990
Otherwise, it is still bad that you need to wait to get the GPS fix.
iPhone really gets it in 1 second.

So buy an iPhone. I've never had GPS problems with the S2 provided I regularly clear then update the ephemeris data (which is basically the position of the satellites at different times/in different locations; in GPS Status - tools/manage A-GPS state - reset data then download new data), and then put the phone in flight mode (obviously with GPS on) & stand outside with good line of sight in all directions to enable it to 'learn' where the satellites are for 5 minutes or so/until you get a good fix. This has always enabled me to get a fast/accurate fix for a couple of weeks until the ephemeris data gets old, then I repeat the process.

I do have iPhone 5 ... that is why I could have compared the GPS results.
How do you reset "ephemeris data"?
I tried GPS config for ROOTed phones, but it does not help.
(I set up the country in the settings.)
Generally speaking - if I am in my country, there is no problem.
BUT: Once I am abroad and have cellular data turned off, then I cannot get GPS in my photos.
I tried about 10 ROMS - but all are the same ===> no GPS if you take photos when you are abroad.

Getting the GPS on the Titan work in standalone mode

Have anyone got the GPS on the Titan to work when you don't have network service?
I have even tried this:
http://www.rimweb.in/forums/index.php?showtopic=13024
I can get my Titan to pick like around 10 sats but it's very unlikely that I will get a lock (1 of 20 times I get a lock).
Cliff notes: What do you have to do to get the GPS on the Titan to work in Europe?
Thanks
Without data, as long as you don't enable aGPS it will work in offline mode, however it's very intermittent on sync. The best method is to turn it on, give it a clear view of the sky either outside or in your car and just wait. If you are driving it will almost never sync up.
Get a tool like Bafs GPS Toggle. As it won't "time out" like Google Maps and Live Search will do. If you just wait it should eventually sync up.
As for outside the country, I am not sure if any of the primer tools like QuickGPS will help, not sure if they will download the ephemeris data for those areas. The first satellite your phone can link onto will then transmit ephemeris data to your phone and tell it what other satellites should be visable at the moment and the upcoming schedule for the upcoming time periods. It then attempts to connect to the others. If it can never make that initial connection then you may never get a sync.
Just give it some time. Mine never took more than 15 minutes while standing still, tho while driving I drove for over 30 minutes once with no sync, however I came to a long stop light 2-3 minutes, and bam it synced. So the trick is to just sit still.
I've never been to Europe, so I can't guarantee that my advice will help.

Thanks but I already tried all that, it doesn't seem to work when you're outside the US, I have left the phone for hours under clear sky, sometimes it will even reboot and I will need to start priming the GPS again.
There must be some special setting that I need to do in the phone.

i don't know for sure if the following will work outside the US.
open up a registry editor, i use PHM Registry editor
go to this key
HKLM/SOFTWARE/HTC/supl agps
change the following, if they need it, to:
EnableAGPS 1
EnableGPSSmartMode 1
GPSMode 4
click ok, quit the reg editor, do a soft reset and go back to make sure the settings took.
this will allow you to use the stand alone gps without the need of being in cell tower range. google maps will not work, since it uses the data connection to load the maps.
GPS Mode 4?

Isnt GPS Mode 4 only for Sprint users?
i don't know myself if it is carrier specific.
i do know it works on my sprint mogul.
Hi everyone, first I want to apologize for my bad english, I will try to explain my problem. I'm from Venezuela, my cell phone carrier is Movilnet, my Titan setup is ROM DCD 3.3.4, Radio 3.2.50, PRI 2.03. The problem is: when I'm on cell phone service area my GPS never gets a lock, unless I let the phone all night with the GPS software trying to lock.
But, when I travel out of the city to an area whitout cell phone coverage, I can get a lock within 2 minutes, consistently, even after a soft or hard reset.
I'm using VisualGPSce to monitoring and priming the GPS, but I also had tried GPS Test, GPS Viewer, GPS toogle, etc. I had noticed that, when I'm trying to lock with VisualGPSce, the software give me a initial position that is 180º wrong, i.e. If the right coordinated is N8º 20,91 W62º 39,14, the software shows N8º 20,91 E62º 39,14. I had tried in flight mode with no success, also disabling aGPS in the registry, may be I will try a QPST config, but I don't know what config can I change.
My thery is that the cell phone towers create some kind of "conflict" and messed up all the GPS syncronization, may be the time syncronization, I don't know.
Thanks for your help.

Won't get a lock with those settings... I will pick a lot of sats but will never get a lock.
Seems the GPS on the Mogul won't work in Europe or anywhere outside NA.

I am using a rom made by myself with BuildOS but I also tried DCD and other ROMs with the same result.
If you have any suggestions, please let me know.
i had an idea of you trying to get a gps lock without installing the carrier cab..just to see for the heck of it.

Well, that's exactly the point, getting a gps lock when you don't have a carrier (no network service at all).

Believe me, I've tried all modes.
I supposed mode 2 would work because that's the factory mode on the GSM models that works on networks with no aGPS, yeah, I have even copied the settings from a GSM TyTN II and a Touch Cruise, they won't do the trick on the Titan.

After the hard reset, the default registry settings was:
EnableAGPS 1
EnableGPSSmartMode 1
GPSMode 2
That works in the no cell phone service area, but in the city, doesn't work.
you can use standalone gps with some of the radio versions:
3.35.04: gps mode 2: no lock, no reboot
3.39.10: gps mode 2: one lock, 1x reboot effect
3.41.00: gps mode 2: 3x constant locks, good navigation, no proven reboots
3.41.00: gps mode 1/disabled smart, disabled agps 0x constant locks, 2x proven reboots
3.42.02: gps mode 2: 1x reboot effect
3.42.30: gps mode 2: no lock, no reboot
3.42.40: running: 3x lock, 0x reboot (disabled smart, disabled agps, gps mode 1)
3.42.50: gps mode 2:1x reboot effect
i used own cooked rom with ppckitchen 20931, a gps software to initialize it (Sirftech, free) reprogrammed the phone with qpst (all gps checkboxes on like recommended somewhere in the forum) and much patience... a lock need sometimes up to 2 hours from window (had to connect the phone on the glass in 2nd floor), outdoor it locks while remaining in the car and myself going shopping for some time.
Sometimes with working configuration it never locks, sometimes it does, no matter how much sattelites in view (mostly 5 to 10)
The reboot occurs in my opinion in the moment the phone gets a lock - some user assumed it only happends if you stay outside usa.
I am in germany (no network available) and have disabled phone, wlan, bluetooth.
Try 3.42.40, use gps mode 1, disable agps, and use sirftech - if that doesnt help, post again...

THANKSSSSSSSSSSSS!!!!!!!!!!!!!!!
That's exactly what I needed to know!!!!
I'm using 3.42.50, now I know why I can't get a lock.
I will flash the 3.42.40 radio, I hope I can do the same on the Vogue.
Thanks again!!!!!

Posting again... After around 40 min, the phone rebooted, no lock at that moment but it was seeing 4 sats.
Do I try with a different radio or different settings?
Thanks
I now have 100% gps reception after letting the device ~20 minutes in the car. So i will post my configuration and hope it helps:
ROM Version: 3.08.666.1 (ppckitchen selfmade, nothing special included)
Radio Version: 3.42.40
Hardware Version 3
PRL 60613
PRI 2.03_003 (these doesnt really matter in airplane mode)
I use the "10 items" communication manager with all disabled except of flight mode.
Registry: Default from rom plus the following changes:
HKEY_LOCAL_MACHINE\SOFTWARE\HTC\SUPL AGPS:EnableAGPS = 0
HKEY_LOCAL_MACHINE\SOFTWARE\HTC\SUPL AGPS:EnableGPSSmartMode = 0
HKEY_LOCAL_MACHINE\SOFTWARE\HTC\SUPL AGPS:GPSMode = 1
HKEY_LOCAL_MACHINE\SOFTWARE\HTC\SUPL AGPS:QoSAccuracy = 25
HKEY_LOCAL_MACHINE\SOFTWARE\HTC\SUPL AGPS:QosPerformance = 89
HKEY_LOCAL_MACHINE\SOFTWARE\HTC\SUPL AGPS:TimeBetweenFixes = 1000
All values are decimal, not hex!
i think that changing QoSAccuracy from 50 to 25 and TimeBetweenFixes from 1 to 1000 had absolutely no effect. So you should try to change only the first 3 values...
in QPST service programming i have disabled "Allowed" because i read it will not disable the gps but the agps - thats true. I have checked and unchecked all boxes, checked only Autonomous and GPS/AFLT Hybrid.
... in all times i got a lock i started the device from power off mode (pressing power button long time)!

[Q] off network navigation

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.

GPS PROBLEM (SGS3 lossing gps lock)

I have the international sgs3 with 32gb, non rooted, everything is stock. My rom build number is IMM76D.I9300BUALF1. I can get a lock very fast (<5 secs) but after ~15 min the phones looses the gps lock!. This happens with all apps: Google Maps (ver 6.6, i don't use 6.9, it is to glitchy), latest igo and gps status. When this happens gps status shows me that the phone sees ~15 satellites but is not locking on any of them (to be more precise: when i open gps status it shows 0/15 fix/stats ). It does not lock again until i disable gps from settings, and re-enable it after a 10 sec of inactivity. In location services i have everything selected. i always have data connection. I am in Bucharest, Romania (if it counts). It always loses lock after ~15 min, it doesn't matter what i do, what app i use, or what time of day it is
Please help. What is the problem? I have cleared and re downloaded agps data with gps status and it still happens. Is it solar activity? if so, anyone else has this issue? Is it a faulty gps unit in my phone? Is it a common problem with sgs3 or with this rom? if so, we should make this problem known. Any help is appreciated.
My GPS works fine.

Hi. I also have the SGS3 - I9300, International, non rooted, all stock, in australia.
GPS has worked fine for me - did a 3hr trip, kept GPS lock (as far as I can remember) all through the trip. Even when it lost cellphone signal.
I was using the NAVIGON app (included, maps are predownloaded so I don't need internet connection through the whole trip).
I've even had it get a lock inside buildings - usually even normal GPS-es have problems with GPS inside buildings...
So it might just be your specific phone. I don't know whether your location matters - is it always pretty much on 15min? If so it's possibly a manufacturing error. Can you take it back to where you bought it and get them to send it in for warranty fix?
If it's a manufacturing error, they should be able to get it fixed for free.
Thats old firmware you could try updating .
Certainly GPS is not a problem on SGS3 .

How much OFFLINE Nokia maps are???

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.
Sent from my Nokia Lumia 920 using Board Express
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.

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?

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.

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.

[Q] GPS lock problems after x-minutes

Hi,
Since two weeks I'm having GPS lock problems on my Samsung Galaxy SII. It had been working fine for two years.
I'm not sure if it's related to the 4.1.2 upgrade I did two weeks ago.
If I go outside and start any sport tracking app I almost get instantaniously a GPS lock. Opening GPS Fix shows 11 satellites and 9 satellites with a lock.
When I start the sporting activity after a variabel number of minutes (could be 12, could be > 30 minutes or could be even > 60 minutes) I get a GPS signal lost. Opening GPS fix shows a large number of satellites but no lock. At that point rebooting the phone (but this is not an option while sports tracking) is the only solution.
I've tried everything related to this subject. (factory reset, playing with the Google location services, etc). The only thing I haven't done is downgrading the Android version.
Any thoughts on this subject?
Thanks
Try a clean install of the stock rom you're currently running (get one from Samfirmware), then try downgrading (not 4.0.4 tho). Or perhaps try a custom rom/kernel ?
