Just curious if anyone else has issues with GPS reception on their sprint touch. I upgraded to the latest htc rom earlier in the week and everything is great except I cannot get GPS to hook up - I've had it work only once.
i upgraded too and i'm using GPS with GoPilot Live, iGO8 and Garmin Mobile XT and it works without issue.
what GPS program are you using with your touch?
Google maps is the only application i've tried. It will search (and search, and search) but doesn't find any or only 1 sat.
Make sure all your settings are correct and try using something like GPS Viewer to get the initilal lock.
Any hint on which settings, and what the the correct values for those settings would be?
Thanks for the tip on GPS Viewer - I will def check it out!
Thanks,
Tim
First, make sure you have the proper Radio/ROM, I assume you do.
Second, under System Settings>External GPS
Programs>COM4 Port
Hardware>(None) Baud Rate>4800
Access>Check Manage Automatically
Third, under Personal Settings>Phone
Services>Location Setting>Location On
Fourth, the Registry
I know of only one value that may help if you change, there are more, but haven't seen them, and I believe it's different on some carriers, like Sprint
HKCU>Software>HTC>SUPL AGPS>GPS Mode
For the inital sat lock, make sure you stand outside on a clear sky and wait at least 5 min, if it takes that long.
The first time I did this, I was trying from inside, finally tried it outside after 3 days of no luck, but now it works quite well. I usually get connected under 30 seconds. As long as your in the same area when you reconnect it should be quick, the first is usually the longest. And I personally use LiveSearch for the directions.
Change from 2 to either 4 or 1, this may help, never really guarenteed though
I was in Boston this weekend and noticed the GPS on my Touch would not lock in a signal in the financial district surrounded by tall buildings. But when I have a clearer view of the sky it works fine. Are you in an open area when you are using it?

It surely helps! Any obstructions will make it harder to pickup the signal.

I was having problems with mine too until I did the 4th one and changed it to a 1 from 2 and it works much better. Try it and see you can always turn it back to 2
This helped me

My apologies if this has already been posted somewhere. I did a search and came up empty...
So like a lot of people, I've been having some major problems with the GPS's reliability on the Touch (yep, last week's flavor of the week). It connects only when it feels like it, and numerous resets seem to temporarily solve the problem. Well, changing the following registry value seemed to solve all of my problems:
[HKEY_LOCAL_MACHINE\Comm\ConnMgr\Providers\{7C4B7A3 8-5FF7-4bc1-80F6-5DA7870BB1AA}\Connections\Phone as Modem]
"Enabled"=dword:00000000"
Change the value to 0, and soft reset.
It appears that the GPS, by default, makes use of the "Phone as Modem" data connection to take advantage of aGPS, but if a "Sprint PCS" data connection is already active, the GPS doesn't swap connection methods and ultimately hangs. This problem is exacerbated if you have Push services or other data connections running.
I personally haven't noticed any problems with disabling PAM, but as usual, your mileage will vary. For me, I get GPS locks within 15 seconds when I'm in a reasonably accessible location, and I no longer have to reset-and-pray to get this thing working.

Link not working, repost.
hate to tell you this, but if you are using the builtin GPS, a clear view of the sky does nothing to improve your gps position locking. our phones have AGPS which means it is fake GPS. It uses the distance from cell towers to triangulate your position, not satellites. Thats why you can get a lock inside with no view of the sky.
some ROMs have different settings on them so following the above directions should work. Or you can do like me and find a better ROM
HI
I'm having a problem with my GPS, it always shows me a location shifted like 250m from the place I am at that moment.
any idea how to solve it?
thanks!!

What software are you using? you may get a faster answer if you mention it
i dont think you can calibrate GPS..
you updated quickfix?
thanks for your answers, I'm using Garmin XT and google maps, then I don't think it is the software.
quickfix? sorry I don't know what is it, I will check now
ahh quickfix is the same as quickgps, yes I'm using it!
Does it just happen lately? Maybe hard resetting would help.
thanks but not really.
well I have my HD for already 6 month but I just start trying the GPS in the last 2 weeks, because I'm in China and was difficult to find a good GPS software for Asia, but I hard reset it couple of times since I start using it.
It might be a hardware issue. You may send it to a distributor center to check.
I was hoping it was not a hardware problem, because it always shows me like 250m to the south west, it's not a random problem.
any idea?
thanks!!
It's very difficult for the GPS "engine" itself to consistently report a position with such a fixed error.
I once saw a similar sort of error when I was using some GPS software which had the MAP DATUM set incorrectly.
Is it possible to change this setting on your software ?
Good luck,
- Steve

Hi, sirrick1.
Nothing wrong with your GPS hardware/Software.
As required by Chinese goverment, all GPS map data should be added a deviation. ie. if you want to use a GPS coodirates that get from GPS hardware directly to locate where you are in map, you may find location is shifted.
Anyway, you can get more information from chinese gps forums.

i tot from history there was a air incident caused by purposely inaccurate GPS and the authorities ( not talking about china ) decide to not hamper the raw signals..
btw from what i know of GPS, you are caculating based from a few sats in space.. so is it possible in maths to get constant SW 250 results? not sure ... i am not a mathy.. anyone?

The shift algorithm is a goverment secret, and the shift value is diffrent in one area from another.
So, it is hard to get/infer the exactly algorithm. So far as I know, the only succeful method to "correct" map coordinate is table look-up that is can get relative "real" values.
it's caused by the MAP it Self
not hardware or the software
May not be due to your GPS hardware.
I have the same problem with my MapKing Navi software, it's off by about 20m. I know it's the software problem, was the same on my iPaq previously. So you may want to find out if your software has the same problem on a device of a different brand.
in china the map are offset by 250m by government for unclear reason, on garmin you need to apply a patch to fix it, what's not clear it's google map, min is working well.
well I tried the patch, which is only a file (006B082300.bin) which must be copied to the folder containing the map, but the problem reminds!!
anyone has success on this?
I had similar problem on motorola a1000 running SmartcomGps, which uses maps in .ogf format. I have great maps made by army cartographers, calibrated precisely, and gps device kept missing position by 100 meters. I also thought that is army's stupid trick in case enemy obtain maps to be deliberately inaccurate. Tried recalibration, succeeded, but still not satisfied, kept googling for days and finally found the solution: on calibration, all maps are assigned with datum WGS84 by default. Changed it to Eastern Europe and bang! - device is locking position dead accurately.
Try this:
Start program, load map, then tap Map/Calibrate/Settings/Map Datum. Choose datum "South Asia" or "Hu-Tzu-Shan" or any other you might think is for your part of China. Try it, if it doesn't work properly then try some other one and do so untill you find proper one. Don't waste your time (and risk screwing something up) with patches, flashing different ROMs etc. Both your hardware and software are OK, just need correct setting.
Hi all,
I own a Samsung Galaxy S (GT-I9000) and I'm running Android 2.3.4, CyanogenMod-7-Nightly-GalaxyS.
There seems to be a problem with my camera geotagging. I have enabled both Wireless networks and GPS satellites and I have turned on the 'Store Location' feature in camera settings. However, whenever I take pictures, the geotag doesn't seem to work and the pics often come out with 'Unknown location'.
Sometimes it works and sometimes it doesn't, what I've noticed is that, it only works when the GPS is locked on a location, like when I'm running Sygic in the background. When I don't have Sygic running, the pictures always come out with Unknown location.
As far as I know, the camera is supposed to geotag the pics based on two modes, either through wireless network or/and GPS satellite. That means that even if my GPS is turned off, the camera should be able to tag my pics with my network location (even if it's not accurate). However, that's not the case with me, the pics are not geographically tagged at all, despite the fact that the location positioning through wireless network is always turned on.
Has anyone else experienced this problem? I have tried searching for similar problem but I have found no relevant threads with relevant solutions. I hope someone is able to help me with this. Thank you for your time.
AFAIK geotagging has only ever used the gps for location so it will only work when gps is locked.

Hi Mark,
I can't say for sure, I've come across sources saying that both Wireless networks and GPS satellites can be used for geotagging, but the former often gives inaccurate tags. I have tried searching for a definite answer from an official source or something but couldn't find any.
That aside, I usually have my GPS satellite turned on anyway, but the pics still come out untagged. Upon launching the camera app, do I have to wait for the GPS to get a lock first before snapping the pic? I have tried waiting, but the GPS gives no indication whatsoever that it's even trying to get a lock.
If I have to wait like a minute or two before taking a pic before the pic is able to be tagged, I think that's pretty ridiculous cz seriously, who launches the camera app and leave it idle for 2 minutes before taking a pic right?

This is how I'm doing it.
When I cannot get a lock on the gps, I turn on the 3G data, and open gmaps.
After I get a relative position through my network antenna, I leave gmaps (not close it!!!) and switch to camera.
Before I used open street maps, and sometimes it didn't require the 3G connection, but now I'm just doing the gmaps workaround.
Afterwards it's picasa, and if I got a geotag position on the first picture, I just use that location for the rest of the album
Hi Cristi,
That's pretty much similar as leaving Sygic running in the background like I've mentioned. That's more like a workaround and not a solution. Besides, running Sygic or any other navigation app will kill the battery quite quickly. I'm trying to look for a permanent solution or at least detect the source of the problem to begin with.
You must have a fix, since you don't know where you are before the fix...
With GPS the first fix can be quite long (cold start) since you have first to downloads the ephemerides. After that if the GPS is well initialised it will reused the previous downloaded ephemerides (hot start) so the fix will come sooner...
With assisted GPS, you can download the ephemerides from the network rather than the satellites, so the first fix is normally quite fast (a few seconds). That's sufficient to tag pics (on many devices it's working quite well).
However if the A-GPS is mis-configured or if the reception is bad (not many satellites - cloudy weather - under a bridge or inside a building) then fix will take longer
So the first thing is to configure correctly the GPS (verify that it doesn't restart always using cold start and, eventually, enable assisted GPS to have a fast 1st fix).
If all is configured correctly, it should improve the time needed to obtain the 1st fix.
However if you have a bad GPS on your Galaxy S, your not lucky !
You can try somel of the many GPS fixes you can find in these forums. For some people it seems to work (but not for everyone...).
You can also try to convince your support to exchange your SGS. If you're lucky you will obtain a good one.
Hi Herbert,
Thanks for the suggestions on fixing the bad GPS, I know a lot of people have been saying that the GPS on Samsung Galaxy S is a bit faulty.
I understand that the GPS needs some time to get a lock on a position, but what I'm more concerned about is the fact that the GPS icon shows no indication whatsoever that it's trying to get a lock upon launching the camera app. So, how long must I wait? 10secs? 20secs? Anything more than that is a bit pointless I think.
Another thing is the wireless networks tagging, the fact that the camera is unable to tag the pics based on the network location puzzles me. Anyway, for the time being, I'm just going to assume that my current telco doesn't support network positioning. I'll try it with a different telco and see how it goes.
I installed Compass from App Market...when the gps has already locked a position that is when I start to use the geotagging.
Hi Darl,
I am using GPS Assist to temporarily workaround this problem, I run GPS Assist before launching the camera app. The GPS Assist locks on a position quite quickly, it usually takes around 5seconds or so, provided I'm in an open area that is.
However, I'm still looking for a permanent solution.
No clue whats goin on...
I wanna use GPS and it keeps searching for ages without getting a fix.
So I ran GPS Status app and it shows many satellites - at one point I had fix to 8 or 9 Satellites?!
3 or 4 should be enough for a location, I don't understand why the GPS keeps searching without getting a fix when I already discovered 8 satellites?
Anyone have an idea?
My system is heavily modded (debloated hardcore) but I'm pretty sure thats not the real reason. Using xprivacy and afwall (but allowing the Android System and the apps I want to be able to use GPS the location and also internet access...) - this setup worked fine in the past on my N7000 without any gps problems. (even removed the NetworkLocation.apk since I dont want to use network location anyway and its not necessary for gps either - tested that already on my old N7000)
Satellites are found, but no location?! Really weird....

I think I have posted a similar story with my tests just today in another thread - does it make any difference if you have your mobile (cellular) data started (and WiFi off)?
I suspect there is somewhere a more extensive configuration for the GPS circuit (maybe including something about whether to use Assisted GPS or not), but for the moment I did not have enough time to look for more details on this
Hi, i just made this account to post this problem here and I hope I find help. My s5 is not rooted and brand new (3 days?) with the version 6.0.1. My phone does see the satellites but it doesn't locks on them so I don't have GPS at all except with WiFi and the other things but that is kinda useless and not accurate. If I really have to I would root my phone cause it's annoying as hell and I'm a traveller so I need that and I don't always have internet. Hope you can help me
Kind regards
Same problem, similar situation, using SM-G900A, Galaxy S5 with AT&T. Satellites show with GPS Tools app, but Google Maps and Waze don't find GPS location. Tried many things, including factory reset. No joy...
