Hi
I wonder if someone has this same problem and know how to solve it...
Most of the times that i try to use tomtom or wayfinder, the gps can't get a fix, it locks on to the satelites with no problem, but only for 1/2 seconds, then loses the position and after some 10s it regains the position again for another 1/2s and loses it again...
The only i way can get the gps to function properly again is by turning the phone off, remove the battery and turn it back on. Then it works, but if i turn off tomtom and try to use wayfinder the problem returns, and sometimes also happens after i close tomtom and try to use it again later...
It's driving me nuts i did a hard reset and after instaling my programs the problem remains. It seems google maps works ok, tho i'm not sure as the program doesn't have the option to see to how many satelites it's locked on.
any ideas? I doubt it's from the programs i install cause the ones i use i dw them all from this forum...
Thanks
its probably your location, the satellites might not be abundant enough. GPS works fine for me, I'm using IGO8.
no, it's not that, cause when it happens i remove the battery and reinsert and turn on the phone again, and after doing that procedure the gps will lock with some 6/7 satellites and will not fail as long as i don't turn off the first program i try to use the gps with ...
If i use tomtom after doing that battery removal procedure, it will work flawlessly, if i turn off tomtom and use it right after, it still works ok, but, if i turn off tomtom and after i use wayfinder, or if i only use tomtom again after some hours, it will have that problem (and vice-versa), it does find the same satellites and gets the coordinates (in tomtom they get those blue level bars), but only for very brief moments every 10/15s which ofc makes it impossible to correctly use the navigation program
If the gps was broken or something it wouldn't work ok after i removed the battery... i guess i'll try another hard reset
Try to disable A-GPS.
possible corrupt quick gps file , run quick gps and downoad new file.
Hi,
If you have used Advanced Config and enabled A-GPS, disable it as it will cause issues with TomTom and other GPS navigation software.
Later...
hehe got it working now, i had tried that before, but seems i was using an older version of advanced config or something, i downloaded a new version, disabled a-gps and now the gps is working fine thanks for the help
Re elusivo
Elusivo, could post how you fixed your problem? Because I currently have the same problem, but no Idea how to fix it. You said something about using a new configuration with and old one? Can you please explain?
Search for the program 'Advanced Config' on the forum and install it and then run it. Go to the GPS section and if A-GPS is enabled disable it. A-GPS uses the phone masts to triangulate and get your position which causes havoc when you are trying to use the internal GPS
Thanks for that......Problem solved
hello
I do have the saame issue as you with my gps. I install Igo, tomtom, gps htc tools and gps skinner and it is always 20/30sec to get a fix but it loses it 1 sec after.
If I disable A-Gps, it will increase the time to fix satellites or is it just used for quiick gps to download ephemerids???.
I think we have to ask Customer support because it is unacceptable for such an ewxpensive phone to have to disable functionalities such as A-gps to get it to work

A-GPS uses Cell Towers to guess where you are. It is not (on these phones anyway) linked to Quick GPS which is a lot better at getting you a fix on a cold start.
As others have mentioned for some reason with A-GPS enabled TomTom doesn't like it, and I don't know of any real reason to use it.
@artesea : I don't get why you said "I don't know of any real reason to use it".
Are you talking about Tomtom or about A-GPS function ??
Because if you are speaking about Tomtom, I do have similar problem with all software using GPS.
And if you disable A-GPS function you are going to have to wait may be 3 minutes or more to get a fix instead of 40seconds so I think this is a real reason to use it...
No I'm talking about A-GPS.
Have you tried a cold start using Quick GPS, I can get a location in under 30 seconds.
So I disable A-GPS and I got fix within 30/40 seconds and I never lost it.
I just think it is absolutely unbearable to have to disable A-GPS to get your GPS working properly. This mobile phone cost 700€
I just would like to know what is protocol version from people who can have A-GPS working properly.
Rom version : 1.02.933.3
Radio version : 52.43.25.24W
So you've gone from 20/30 seconds to get a fix but then it drops, to 30/40 seconds to get a fix and it work and you STILL have a problem???
Maybe there is a reason why A-GPS is disabled by default!
No when I disable A-GPS I don't have problem any more.
I just remembered that I may have enable A-GPS through Advanced Config.
Hard reset do not change this, I though it was a registry editor value but apparently it is more than that.
Anyway it is not Xperia X1 issue but Advanced Config compatibility with Xperia X1
having problems with gps now too :/ later it was working brilliant (fix in no time), but now, most of the time i dont even see any satellite...
but sometimes, especially after reset, it shows like 5-6 satellites, but cant get fix, after some time sats just disappear :X tried disabling/enabling a-gps, with/without quick gps file downloaded, still the same... and no answer anywhere...
i guess i'll have to use my warranty and get it serviced :/
edit: today reflashed radio one more time (as yesterday after like 5 radio flashes, i ended on the original version, not the newest one) and suddenly gps is working hope it lasts...
Hi all..
Iam unable to geotag with my omnia 2..
When i select gps in camera settings, it just says "receving gps signal" and then nothing..
Has any one been able to geotag.. Or is there any settings i need to change..
Photo Gps
It took close to 60 seconds before the recieving gps signal loaded after this the window closes..This is what happened to me...
Hope this helps
On my it just says "receving gps signal" and nothing.. waited for around 2-3mins...
i am not on 3G connection.. does that matter.
Make sure under:MY Menu / Settings / General Settings / GPS / Connection: Scroll down and make sure the button for Manage GPS Automatically is on. Some programs will not use the gps unless this is activated..
Hope this may Help..
Bronson
Manage GPS Automatically is on.. and also my Garmin works fine..
Have you flashed your unit with a new Rom here or changed your default Gps settings in order to get your Garmin to work?
Some have stated that using certain memory cleaners have wiped certain files needed for some functions.
I got caught the first week of downloading and using pocket mechanic and lost sound files for most apps...Only recourse was to Hardboot and try again.
Hopefully this is not your issue but thought i would but it on the table..

My geotagging works fine it is obviously a gps issue so try THIS
I got the same problem. I'm still using the same Samsung ROM that comes with my B7610. I turn on GPS from the camera submenu. However, I keep on getting the error "Fail to Receiving GPS Signal".
hi guys,
when i try to use gps (with syngic), it takes a lot of time to search satellites. when i had WM, there was an app that downloaded satellite's data every week. there is a way to have a faster signal search in android?
thanks

Mine does it already, when I enable GPS, the mobile connections kicks in and I get a fix in no time
as far as i know the aGPS ( assisted GPS ) can use the network towers to make a quick location fix within a radius of 1.5 Km, but you need to have this function active.
knowing roughly where you are helps the gps to select the needed data from the satellites.
last week i got a gps fix in less then 20 sec.

but AGPS needs data connection
My LG QUANTM MODEL C900B only track by WIFI or by CELL TOWER TRIANGULATION.. It appears that my phone dont detect GPS signal because it use only those two metods.
My phone is new and I have tried a lot of things, I reflash the phone, turn off the Location and then turn it on, RESET but the phone only detect my position by WIFI and cell tower traingulation.
This particular model is AGPS only or my unit is defective? The phone detect my position but it cannot track my movements because for that it need the real gps signal from the sattelite.
I don't know anything about anything so I have to ask...is there a setting on the device that allows you to enable your location? And if so, do you have it enabled? On my older winmo device there were to places to enable my location...one is for weather, the other is in system settings/location
Yess the problem I got is that my phone only takes cordinates from A-GPS and not from GPS. I can see where I am but it did not detect any GPS satellite. And yess everything is on. Location Services are on
Try this... Use a map app that would usually use GPS... When it triangulates near your position, but not actually your position, leave the phone for a long time and it should work...
If this works, then each time you use it it should be much quicker...
My phone only triangulates positions and can't use the gps satelites, maybe the gps radio is bad,something I doubt because the phone works flowessly exept the gps radio. I will try to reflash reflash the phone with the original firmware ti try to correct the problem.

Try using the GPSInfo app. Let is sit under open sky conditions for more than 15 min. The first time a GPS gets a lock can take quite a while.
Hi,When I use my phone for finding my location without using data connectivity - without relying on A-GPS so my phone finds my location after a lot of time or sometimes google maps can't find my location.
How can I solve this?
Thanks.
After day or so it won't get fix at all. Samsung just did something wrong I'm afraid. Looks like the GPS in SG2 NEEDS data to work. I found the hard way on my trip to Japan. I know no solution.
So I cant change my gps settings?

GPS in the S2 is weird. Some days it locks in seconds other times it takes forever. I never use A-GPS.
Today I couldn't get it to lock but last night it was instant. So I restored a CWM backup from last night, rebooted and it locked instantly.
I played around with MIUI for a couple of days and found lock time much better than stock or custom rom.
Also, changing server with fasterfix makes no difference when its having problems locking.
I just don't get it.

GPS Aids in Market. It will take a bit of time on first lock but from then it will be fast.

How do you 'never use AGPS' ? Btw. my problem is not time of the lock. But the fact, that without network, I don't get fix AT ALL. With network AGPS reset helps (many apps can do that). But without network GPS works only for some time (AGPS data still valid). After that you just won't get fix. It even looks like wifi connection won't help, it has to be mobile network.
It's because of crappy gps reciever or it can be improved by another rom?
Thanks

It seems the problem is that GPS is in mode, where it simply relies on AGPS. In older ROMs there was app called LBSTestMode where you could change the mode to stand alone, or just AGPS based. This application is not in newer ROMs, so it cannot be switched. It clearly is just a software thing. Except it looks that there is no solution which does not involve flashing roms and/or rooting.

Yeah I never use it. I don't tick 'use wireless networks' at all. To me that's fake GPS.
Since my last post, GPS has been perfect. Am able to lock up to 11 satellites sitting on the couch. On average it takes about 10 seconds to lock. Tested it at least 20 times today.
But who knows what will happen tomorrow!!!
Man, if you can only get a lock using wireless networks then I think your GPS might be stuffed.

That does not mean you don't use AGPS. AGPS is method, where data about GPS satellites are not downloaded from those satellites via GPS receiver, but rather from server via. mobile network. So I'm afraid you do use AGPS, unless you disable mobile networking (and wait about day for current data to become obsolete).
One thing I've noticed is that when I run Z-DeviceTest and bring up the GPS status display, it shows that none of the satellites have almanac data, and very rarely have ephemeris data. If that's accurate, that would suggest that if you've turned off AGPS and mobile networking, you could have some trouble.

Nice find. First app I know which shows this. Now I can test if that almanac is downloading via GPS satellites or not.

Ok. So does that would mean it's impossible to get a GPS lock without data enabled? Or just harder to?
Maybe I shouldn't have mentioned AGPS, but instead wireless networks which show your position even though GPS is not locked.

It seems it may vary with ROM, and it is possible to switch it, at least older ROMs contain service menu module (LbsTestMode) to switch it. But my SG2 seems to be unable to get a fix without network. It simply does not even try do download Almanac or Ephemerides data from the satellites.
Also for AGPS, mobile network must be used, not WiFi. As I understand it, those AGPS server names are virtual, and network provider redirects them based on location .. which is not possible via WiFi.
I wonder WHY there is such option at all. Do mobile network providers want us to be unable to get a fix without them ?

Hey Dr, I think you have diagnosed my problem
Every so often I turn off data and use only wifi. One day my GPS locks in seconds then the next it takes forever.
So I have now tested it a couple of times over the last couple of days, when I can't get a lock I turn off wifi and turn on data. All of a sudden GPS locks again. Interesting!!
Hopefully that is it. Will test again the next time it won't lock.

Ha ! Breakthrough. I could get a fix without network ! But ..
I used newer version of 'GPS Status' app. It shows state of unconnected satellites with gray/blue/yellow based on how much data it has - none/almanac/ephemerides. So you can see if there is some progress or not.
So I disabled network (both wifi and mobile), disabled location from mobile network, left just GPS on .. run GPS status and used 'Reset AGPS'.
The connection has few 'phases':
1) you get signals from satellites .. you see it in power meter .. all are gray .. and their dots on the 'sky' view are all in the N. Sure, GPS does not know where the satellites are, and does not know where you are .. so it can't know where on the 'sky' they should show.
2) Some signals/dots turn blue. That means you have almanac data. Rough position of all satellites, which is transmitted by all satellites. That already means your GPS receiver was used to download some data from the satellites. Based on this, GPS can tell very roughly where you are, and will paint dots on the skyview.
3) Some signals/dots turn yellow. That means you successfully downloaded ephemerides data from that satellite, and it can be used in fix. Have enough of them, and you are done.
4) Some signals/dots turn green - you have fix. The error will get better over time as more satellites are used.
I took me over 5 minutes .. but thanks to this tool I could see I'm indeed receiving some data and there is some progress. Also it only worked outside, under open skies. I tried that in a car, in a bus, in a train .. after 10 minutes I did not get over phase 1. With AGPS I get fix in all such situations in few seconds.
It just looks like the data decoding module for almanac/ephemerides is not the same as for the time (which is used in fix itself). While time channel is quite sensitive and fine, data channel seems to have troubles with even slightest disturbances.
Still I'm happy I made it work in the end !
Btw. the fact that AGPS does not work over WiFi still holds.

try fasterfix from market
I rarely have the data connection on (just to save battery) and WiFi is only on where I know I have a known connection - thus it is off when outside.
I put on the GPS then immediately run Sygic satnav program. I will have a fix normally within 30 seconds and a worst case of about a minute (that I can remember).
I have just tried switching off and on my phone, putting on the GPS (from the Pull down menu) and run Sygic. From switching on the GPS, I had a lock in about a minute.

Could you try that with AGPS manually reset ? I recommend 'GPS Status' tool to do it, it's in 'tools' menu.
GPS lock time seems much improved in KJ4 firmware for me (i'm on orange 2.3.5)
all three DOP values in GPS Status now show figures (instead of infinity for two of them), and i'm getting reported accuracies of around 5 metres, instead of 14 - 20 metres on the older firmware.
