GPS "Your location within 1900 meters" ?? VZW TP2

Recently my Google Maps has not been able to lock in on my location closer than 1500 to 1900 meters. I have hard reset and reinstalled GMaps with no luck. I have seen tweaks for Sprint and TMo users and have read that most VZW users are having no problems locking in. Are there any tweaks that I can try for the VZW TP2?

there are numerous gps tweaks to change the cache settings if you search for them. also try using the program quickgps which comes with your phone it will download the closest satellite info. inside my building i cant lock on any sats but outside i can get between 8-9 and within 10 meters of my location

Make sure location is turned on.
If you do the quickgps program on the phone it will turn location on for you and download the closest satelites for you and you should get a lock in like 10 seconds when you are outside.
Unless you turn on location you will just get your general location with google maps, mine said within 2800 meters till I used QuickGPS.

I have duplicated your problem by unchecking the gps option after you open google maps and pressing menu and the down arrow. Make sure the location setting is on as prior post stated and then after you open google maps make sure gps is checked in the menu and it will say that it is searching for satellites.

also make sure you change your gps settings in google to com4 and a baud of 4800
you also have to re-enable the "use gps" after changing this

I was able to dublicate the problem aswell, by accedent >_<, anyway, make sure the location setting for google maps is selected.

confirming what others here are saying, that's pretty much what I experienced with GPS unchecked in the main right softkey menu. If you don't have that checked it's using cell antennas or wifi to approximate your position. "Menu" > "Use GPS" and it should work by default.

Leaving it set to the "Managed by Windows" setting works just fine for me. No issues, and definitely use the Quick GPS program, it saves a headache. In fact im sitting on my couch in my appartment on the bottom of three floors built on the side of a hill with 2 sides of earth, and I have a strong 8 to 9 sats.

I just got my TP2 yesterday and one of the first things I did was install google maps and I was getting result like the title of this thread "within 1800 meters" and it could be a mile off. also the sats were not locking at all. I realized that my position was based on the tower that I was connected to. By the way the google maps on my VX6800 never used the towers to triangulate a position but the gps lock were much slower. Once I ran the quick GPS in the programs menu it turned on the GPS to the right setting and now I get an accurate lock even inside within seconds.

Go to settings-all settings-personal-phone-cdma services-location setting and make sure that it is set to "Location On". If not, you are not actually using the GPS. With that on and with QuickGPS doing it's thing, you will lock instantly.

I have a Verizon TP2 that is two weeks old. It does not have QUICK GPS! Oh yeah, and the gps does not locate.
Do I?
Return it?
Hard Reset? (sounds like a lot of work)
Get the file somewhere?
I have had it twice to Verizon. They have no suggestions but are happy to see the device and get their hands on it.
Leaning towards exchanging it for a new one.

GPS Issue

Is any one else having an issue of the GPS taking an extremely long time to get a lock?
Sent from my SAMSUNG-SGH-I897 using XDA App

Out of the box it worked flawlessly. I messed with a location setting and then gas took around thirty seconds to lock. I turned that setting back on and gas flew again. On average, my gps has a lock by the time the map loads

Could you tell me what your gps settings are then? Also could you dial *#*#1472365#*#* and go to application settings and spul or something like that and list what you have there?

I'd say that driving home the gps got a lock relatively quickly but it was only a lock accurate to within 50 meters. I guess this is good enough for driving but it wouldnt be good enough for biking or jogging.

Mine takes a full minute to lock. I think the issue, at least with mine, is that no matter what I do to the settings, their not saved. So if I go to settings and change location settings, or use *#*#1472365#*#* the settings never seem to save. Not sure if I'm doing something wrong or this is a bug, sure seems like a bug though.

I noticed the first time i tried to get a GPS lock it took forever. But every time since then it has been getting progressively faster. Now it locks and pulls up traffic info within seconds...

I am having a difficult time with the gps locking and it is very inaccurate. I went into the settings and change d the startup to cold
Sent from my SAMSUNG-SGH-I897 using XDA App

whoa, you get traffic info? is that with google maps?

I have been having the same problems. I tried messing with the GPS settings and it seems to have made things somewhat better, though I can't confirm it. Here's what I did, if you are interested.
Dial *#*#1472365#*#*
Go to SUPL/CP Settings
Set server to supl.google.com
Set server port to 7276
Set SUPL Secure Socket to OFF
Go back then go to Application Settings
Set Operation Mode to MS Based
Set Accuracy to 80
Set Use SkyHook to ON
I'm not sure if any of these things made a real difference at all, but I do know that right now my GPS is reporting an accuracy of within 10 meters in a location where I couldn't get a lock before. I'd love to hear if this helps or hurts anyone else's GPS performance.

Thanks this actually fixed my issue of not being able to ft a lock at all. Accuracy is pretty high at 30m but it was spot on in Maps.

Thanks for the tip.
the gps is still not working inside my house, but outside it locks faster outside.
Thanks

I've tried following the directions in the GPS Fix 101 thread under the Vibrant section: no luck... I tried what was suggested abouve: no luck...
Can someone tell em what I'm doing wrong? I know that usually the issue is w/ the operator, not the device and I'm new to Android. I like the phone, but GPS is a BIG reason I bought an Android phone. I need something that is REALLY accurate as we have smaller blocks in some of the towns I go to. Seriously, where my parents live there are A, B, etc. streets and some city blocks are so small there is an "L 1/2 St" ( You can laugh about everything being bigger in TX...)
I do a ton of traveling so this feature is VERY important to me. I just got back from one cross country trip tonight and seldom did I get a good GPS lock and that was on major Hwy's. How does this compare to the ARIA? My sister just got one of those, but hasn't messed around w/ it as it is her first Android phone.
I'd appreciate any help or advice anyone can give. Thanks in advance!!!

If it helps; I was just outside my father-in-laws house and it initially had me about 2-3 blks away in the middle of a golf fairway. It is a clear night, no clouds or heavy trees. I can only detect 1-2 sat.'s when I do a test, and I have a Bodyglove silicon/rubber case/skin.

Ok, I tried it again... In the house I'm about 500 ft off from where I really am and placed in a golf fairway. Outside I am FURTHER off: I'd estimate at least 5 blocks and placed in the middle of a different golf fairway. For comparision sake, my wife's iPhone 3Gs has her within 10-20' while inside the house. I can detect 3-4 sat's. which is the most ever, but it does not use any of them... To me, this is unacceptable and a great cause for concern. What can I do???

I changed my settings to the above, and I've gotten much better results with my GPS. It finds my location a lot quicker, and more accurate. Try these settings if you haven't already. If you have, I guess I would just take it back to AT&T. Having a lagging and inaccurate GPS on a smartphone can be annoying.

For the android newbie... can you give a little more detail on how to get here and Skyhook?

Never mind I found it.

Will/Can this be fixed.
I am very disappointed with my GPS performance in an otherwise very enjoyable phone.
GPS is important to me and I am seriously considering returning the phone. There are a couple of other issues, but I'm working through them.
Do you think the issue will be repaired? Guess at how long until fixed? I know it's all just a guess.

They above settings improved my GPS signal acquisition, however, accuracy was still very poor. This was extremely evident when navigating around town. I'm currently testing the following settings and so far things seem to be working well:
Go to SUPL/CP Settings
Set to AUTO config
Set SUPL Secure Socket OFF
Go back then go to Application Settings
Set Operation Mode to MS Assisted
Set Accuracy to 100
Set Use SkyHook to ON
Using these settings I can reliably track 8-9 satellites and lock 4-5. Accuracy tends toward 5-10 meters and signal acquisition is usually within seconds.
I've noticed that after changing settings it can take the GPS a while to acquire a lock. Subsequent uses improve in speed.
I'm by no means an expert on these settings so if anybody sees a problem with them please let me know.

Thanks goes to Onlyloki for this method.
Haven't had time to test it thoroughly. You may want to do this in conjunction with the first procedure and then do the optional if the first procedure did not work for you. I did both and my GPS is locking even faster. Let me know what you think...
Just some more info I dug up:
Quote from http://www.vzwdevelopers.com/aims/public/menu/lbs/LBSFAQ.jsp
"In MS-Based mode, the network provides the satellite information to the device, based on a rough estimate of where the device is located, and the device acquires the GPS signals from the satellites and calculates its location. After the initial fix, the device operates like an autonomous GPS receiver, until the satellite information must be refreshed, at which time the device goes back to the network to update the satellite information. MS-Based mode is appropriate for applications that require the device location to be updated rapidly, such as a navigation application. Can the GPS work in autonomous mode? No, the GPS receiver requires the assistance of the network elements to acquire its initial location fix."
With the rapid updating we could see an increased drain on the battery. I have not confirmed that yet. If anyone can let us know.
Edit #2:
I was informed by a sales rep at T-Mobile that Samsung is aware of the issue and is going to fix the GPS and the compass issue in their first update.

Mine seems to be working fine after flashing back to stock firmware.

I wasn't able to get a lock before or after the original fix above. After performing the second fix I was able to get a lock but the phone only picked up 8 satellites.
Any idea if I'll have do the second "fix" every time I want a GPS lock?

I was finally able to get a lock using both procedures, but it couldn't track me if I moved.

Same for me. I flashed the stock rom in the other thread, went outside and had a gps lock at 5m in less than 30 second. It locked at 30m in less than 10 seconds. Before this, the best I had was 30m after a long time and it wouldn't track me in my car hardly at all. I will test further tomorrow on my way to work.

Thanks! This worked great, I'm glad I have working GPS now.

Blarg. I am really not in the position to do a factory reset after I just got my phone the way I like it... Anyone else?

I wrote them down before I started...
“Application Settings” change “Operation Mode” to Standalone & “Skyhook” to OFF
“SUPL/CP Settings” change “Server” to www.spirent-lcs.com “ServerPort” to 7275

what about the others under application settings? I think it was one of those.

Samsung GPS fix is coming in September

This is old info and does not fix tracking issue. It only helps lock times. This is already posted in general 3 or 5 times.

not sure if anyone else has addressed this issue but the AGPS is disabled according to the settings.db file. maybe thats the problem?

[Q] GPS takes long to lock in - Galaxy S 4G

I'm aware of the GPS issues with the Samsung Galaxy S. I have the Samsung Galaxy S 4G and I'm wondering if anyone with this phone is experiencing difficulties getting GPS to lock in.
Within approximately 10 minutes, I can see in the GPS Test app about 3 satellites in view. Given enough time, it picks up a few more and eventually locks in.
I've read about the Super GPS fix and the hardware fix but I'm not sure if it would be wise to try it on this phone since the fix was meant for a different model and I don't see any mention of anyone trying it on the GS4G:

Please share your thoughts and experience.

Locks quickly for me without any "special" settings or apps. I even have network-based location always off on my phone since I don't want Google tracking me all the time.
The first lock may be causing you problems if the orbital data hasn't been loaded recently enough.
I have read that GPS Status has helped some by causing the orbital data to be refreshed.

I have a Samsung Galaxy S 4G and a Vibrant, both are horrible with GPS, they both take forever to get a lock and many times they never get a lock and Samsung is less than helpful. They had my Vibrant for three weeks and sent it back with nothing changed.

mine has never taken more than ~30 seconds to get a lock, even if that 30 seconds sometimes feels like "forever".
this is my first GPS-equipped phone, so i don't have anything to compare it to, but once it's locked, subsequent locks take less time. maybe i just got a "good one"?

I have a Vibrant and an sgs4g. There is no comparison between the two. The sgs4g takes about 5 seconds to lock, The Vibrant I've waited literally 40 mins and still never got a lock. It could be the app. Are you having any trouble with google navigation taking along time or just the gps test app?

I know this wasn't directed at me, but I share the same GPS problems.
This issue occurs in all GPS Apps, including Google Navigation. It simply says acquiring GPS....
The GPS icon flashes like it's working, but its not doing anything.

Just kidding, I bought the app. So far it seems to be working well; after doing everything my phone was actually picking up FIVE satellites.
Not working right now, though. I contacted the developer for some help, and I'll post his reply/an update soon.

-Exit the App, and close it with a task killer.
-Open it again, and click "Get Position Test"
-It might take a while for something to show up....but it eventually will. Let it run for about ten minutes straight.
-Close the App again, and you should be good!
Upon Position test....I got:
Accuracy: 41 (meters)
Number of Satellites (INDOORS!): 9

If you have any questions feel free to reply.
Remember, credit goes to "Bade" (which credited XDA forums anywho) of samsunggalaxyforum.com
Running Copilot Live (GPS Application) and finding location took less than 5 seconds indoors.
To check some info out, I ran GPS Test, and saw "In View" Satellites was 9, and "In Use" was 7. (both were 2, to 0 respectively...previously.)
Running GPS Test (another app, different) came up with my location in less than a second.

My GPS was working but I wanted to mess around and check on your findings. I tried to get this to work but it took quite long looking for Satellites.
I noticed when I went in to modify the SUPL settings, it was set to custom config. Made the changes according to your post and like i said before, it took a while so I stopped it. changed the settings to auto conifg and BAM! pulled 13 satellites and locked in within seconds. I do not know if its due to my location but Im working great on Auto Config.
this post is more of an FYI rather than a fix. Hope you guys get yours fixed either way.

On the first try, you have to let "Get Position Test" run for around 10 minutes (The 3 minutes on the original post I said might've been a stretch).
Trying Auto Config, I'm getting similar results, though with the custom settings I had more satellite lock-ons.
Custom:
12 SAT, 10 CONNECT
Automatic:
11 SAT, 7 CONNECT
After doing this, the GPS data should stay downloaded on the phone so future satellite searches are MUCH quicker.
Thank you for your input by the way..I appreciate it

My phone has always find satellites and locked within 30 secs. One day I started messing around with settings and came to find out my gps was no longer locking on any satellites at least for 10 mins. I bought the gps aids v2 app from the market then tapped on gps doctor and tapped on "regenerate" (it regenerates the gps data folder) it made my phone boot up. Since then my gps has been workin excellent after that.

I tried the same thing, except with that app I couldn't download the XTRA data once resetting the settings :/

Me neither, it couldn't seem to download the xtra data, but just by tapping on gps doctor and "regenerate" and in my case that fixed it. Good luck!

Right now as we speak i've followed ALL the steps and have 4 satellites currently showing on the phone while INSIDE my house, in under three minutes time.

-Download LauncherPro first.
-Tap and hold on your homescreen, and select shortcut.
-Click Activities.
-Scroll to LbsTestMode.
-Tap the first one, LbsTestMode (with gray saying com.sec.android.app.lbstestmode.LbsTestMode
-Click okay when "edit shortcut" comes up.
-Open the shortcut.
-Tap "SUPL/CP Settings"
-Change the following fields to...
Server -> supl.google.com
Server Port -> 7276
SUPL Secure Socket -> OFF
AGPS Mode -> SUPL
-Click Back (it saves it)
-Reboot your Phone.
-Click Settings, then Location & Security.
-Check "Use Wireless Networks"
-Go to your Launcher, and open LbsTestMode again
-Click "Delete GPS" Data
-Exit the App, and close it with a task killer.
-Open it again, and click "Get Position Test"
-It might take a while for something to show up....but it eventually will. Let it run for about ten minutes straight.
-Close the App again, and you should be good!
Upon Position test....I got:
Accuracy: 41 (meters)
Number of Satellites (INDOORS!): 9
Speed: (m/s)

Just came across this when I was freaking out about my crappy GPS lock. Just got this phone to use on Mobilicity and was concerned there was some T-Mo setting that needed to be changed. Anywho, this works wickedly. Thanks a lot.

I'm aware of the GPS issues with the Samsung Galaxy S. I have the Samsung Galaxy S 4G and I'm wondering if anyone with this phone is experiencing difficulties getting GPS to lock in.
Within approximately 10 minutes, I can see in the GPS Test app about 3 satellites in view. Given enough time, it picks up a few more and eventually locks in.
I've read about the Super GPS fix and the hardware fix but I'm not sure if it would be wise to try it on this phone since the fix was meant for a different model and I don't see any mention of anyone trying it on the GS4G:

I have the gs4g and tried GPS AIDs with some improvement . At the most I would lock onto 7 satellites when it felt like working. I lifted the contact as indicated in the thread above. I then deleted the old GPS data. Then in GPS AID I regenerated the DATA and rebooted. Now i get 12 locks on satellites all with green signal status. Very please. Google maps Locks on with in seconds....

I think I spoke too soon. I tried this in Calgary and it was great. I'm now in Toronto and I haven't gotten a lock since I got here on Monday. Tried messing around with the settings again, but just won't lock on. Also tried auto config to grab SUPL info from my provider, but that didn't work either. Still working on it.

Start over and flash krylon deoxed with odin, cwm, bionix. This resolved my 10-15m lock times completely. Now I get a lock in seconds.

Amazing!
I tried this and got accuracy within 3 meters off 10 satellites. Before, it was about 80 meters. Just awesome.

You don't need launcher pro to get into LbsTestMode. In your phone's dialer, just type *#*#3214789650*#*# and it'll go into it.
As for what you suggested about going in and messing with the settings, the first lock takes forever because you've wiped out all the ephemeris data by deleting. It starts looking for satellites for your first lock which takes a while with no ephemeris data. Once it gets a lock, it starts downloading ephemeris data and subsequent locks are significantly faster because your phone now knows where the satellites are.
AGPS helps reduce the lock time a bit (by using mobile location and the SUPL server), but not by a huge amount. The largest reduction in time is due to the fact that you have updated ephemeris data. If your ephemeris data is outdated, your lock times will go up again.
If you don't believe me, try this: get your lock. Then shut off your GPS by using the pull down panel. Leave it off for at least 24-36 hours. Then try to get a lock again. It's going to take a long time again...
I've been tinkering with the GPS on this phone for a while now as well as my GF's Vibrant. There's no doubt in my mind that the SGS4G is improved over the Vibrant, but it's still not great.
I've also pulled apart both of these phones and done the hardware fix by bending the little tab every so slightly. Made a significant difference on the Vibrant which was having a problem maintaining locks and the GPS signal was bouncing all over. No noticeable difference on my phone.
My only conclusion is that the antenna on these things are poorly designed and just take a long time to get an initial lock. Once locked, it's pretty solid. Other phone manufacturers have GPS that work better though. No reason why Samsung couldn't do better.

GPS - always wrong locations at beginning

Well, I've been using my Sensation for about a week now and so far everything is fine, EXCEPT one major bug i found:
Every time I turn in the GPS-Option, I get a completely wrong location (ie in weather, maps, places, etc) and have to wait and refresh a short time later to get my actual real position and even short time later, the signal goes back to the wrong place.
example:
I enable GPS and refresh the weather, it goes to "Fürth" (some city in Bavaria, South Germany), but I'm actually located near Berlin (on the complete opposing end of Germany). Same goes for any other location based function.
I even disabled the "allow false locations" option, but don't know further, anyone experienced similar problems?

I haven't seen this. I'll take a wild guess. Part of the A-GPS system can use cell towers and wifi to get a rough estimate of your location in order to speed up the GPS sat acquisition and lock. Perhaps the cell tower/wifi mapping in some parts of Germany is incorrect, so when it's using the local networks to find you it's flipping to another part of the country, the GPS kicks in and it locates you accurately. You could try a couple of things to test this. Turn off GPS and open Google Maps. It will normally locate you on the map within a few blocks of where you are and show a large blue circle due to the inaccuracy. Does it show you near where you are or in the other part of Germany? If it's way off then the local network mapping database is messed up. Not sure who to contact about that, but I guess you would start with your service provider.
As I recall Google has had a bunch of problems with the German authorities regarding the mapping they have done of wifi networks. Maybe that's a factor here, but who knows.
If this is the problem you could turn off the local network feature in Settings > Location. Problem is it will rely only on GPS then and take longer to get your location. But if my theory is right, right now the local network locator is hurting more than helping you.
If that's not the problem then install this app:
http://www.appbrain.com/app/gps-test/com.chartcross.gpstest
Turn off GPS, run the app, press the Menu button on the phone then Settings. At the top press "Clear AGPS" then "Update AGPS". Exit the app, turn on GPS and see if that helps. The initial lock after updating AGPS may take longer than normal, but that's expected. After that it will be back to normal.

I have the exact same problem as the op. soon as I open google maps it shows me 10 miles away from my house. always the same spot 10 miles away. a few seconds later when it gets a lock on my location it pops me back to where I actually am. If I close google maps and open it again it jumps back to the wrong spot again, waits a few seconds and then jumps back to my true location at home.
I tried what you mentioned above but it did not help. wifi on or wifi off same difference. I read about some people saying it shows their old address and I did recently move and the wrong location it shows is about 1.5 miles from my old house. also the wrong location it shows me in is on the edge of this private reservoir that I have never been too.
Anyone else have this problem or read on how to fix it?
