I propose that one of these GPS problem threads be made sticky since we cannot simply search "GPS" here and the GPS problems seem to be accumulating.
With that said, I would have to say that my GPS performance is pretty terrible. At first, it felt like doing the QuickGPS thing and/or deleting the xtra.bin file helped. For the most part, though, getting a lock has proven quite sporadic. What should the expectation here be? Should I expect the GPS to work reliably indoors? What about if I am near a window? Why would it work in some buildings near a window and not in others?
My personal opinion is that the GPS should work within 15-20 feet of a window. Using Chartcross GPS Test, even when the GPS is locked, I am getting mostly yellow bars. I am not exactly sure what a good reading looks like on Chartcross, but there appears to be a 25%, 50%, 75%, and 100% bar. Maybe the 25% bar is 100%? In any event, I rarely have a satellite that is getting above what I suspect to be 30%.
Is there a thread somewhere that details what the various fields mean and/or should read in Chartcross or a similar utility? I am coming up on my 30 days to return the phone, so if someone thinks that my device may be defective please speak up!
Thanks as always XDA-ers!
GPS signals are not strong, you have to be near a window (e.g. less than 50cm) or outside to get it to work properly. Inside I get 8 sats with too little to lock, outside I can get up to 11 locked. I use modified GPS settings to improve the lock. I've created a CAB for you.

Try them and then tell me how it works.
No you cant use it inside, but this has nothing to do with windows. Think of it this way:
To use the GPS, you need a line of sight to the sky, small barriers it will work through (like car roofs). So even a "line of sight" to a window, wont help you because of the thikness of the house roof. To be able to use GPS inside, you need something else, like a big antenna
Anyways, the GPS is for outside/car use only.

That is partially true. The signal can "reflect" off surfaces as well, though - as with light - weaker. And it does have to do with windows simply because a window has a lot (lot!) less density than say, a brick wall. Less density means easier path for the signal. Being near a window does indeed increase the chance of signal lock.

I have a lock when I am inside all the time, usually about 5 satellites or so... out side that jumps considerably, in fact I was very impressed with the speed and sensitivity when compared to my Kaiser/TyTN II/MDA Vario III and I havent used quick gps yet... of course now I said that its going to be sods luck and it will [email protected] out on me...

Well, it depends on several factors. If your home is made of wood instead of brick, that'll make a difference. If you live higher above sea level, it might make a difference. If you live on the countryside, that will definitely make a difference. I happen to live below sea level in a brick house in the middle of an average sized city. My reception won't be something to write home about

I've only had signal ONCE so far with my X1
It was at my living room window.
After that, no signal, ever. Not even out doors.
Im in NYC, plenty of buildings, but cmon somethings gotta be wrong. I even tried a hard reset to get it to work again. Nope... Bastard GPS ):

Run quickGPS and install my cab. Try again and let us know!
Nippero:
you wont get any signal (or good accurate location) if you are in a big city.... your best bet is using google map w/ agps and let the cell tower locate where you are at
another thing I want to point out.... I tried using the gps on x1 when I was on the plane... while it was always able to lock on to a couple sats... it wasnt able to locate where I was at .... and the worst part is after I get back on the ground... the gps stop working and I had to hard reset my phone .... I tested it twice and both seems to be the case... so if you dont want to hard reset your phone.... I suggest you not to try it next time when you are on the plane
You guys must have really big houses to need GPS to work indoors

I really appreciate the quick reply and cab file. I will load it shortly. Is my understanding correct that A-GPS is turned off by default? If so, does this cab enable it? What improvement did you see with your cab file? Lastly, do you use Chartcross GPS test? I'm trying to figure out what the different fields/values mean in it.
Thanks!
Careful with changing the A-GPS to on by default. You can do this through Schapman's advanced configuration tool too, but I've had nothing but bad luck with it.
I use iGO8 and after I turned A-GPS on, the gps signal would drop every few seconds and would have a hard time finding satellites. Switching everything back to factory "defaults" and just using quickgps updates, I've had zero issues. Apart from the initial sat discovery, it's always fast to start and fast to pick back up (maybe 2-3 seconds) again.

GPS is only able to keep a lock under a certain speed. Airplanes are fast, so you will lose the lock. Once on the ground you can get a lock again by running QuickGPS. As your location has changed tremendously (depends on how far you fly ofc), the sattelites aren't where your phone thinks they are.

You're welcome. My CAB does not enable aGPS, as it sometimes causes problems like quoted below. It changes some registry settings that basically tell your phone to keep looking for a better lock, for a longer period of time.

Do not that your individual experience with aGPS doesn't generalize to everyone. I've personally tried aGPS here. It made 0 difference (as far as I could tell), so turned it off again.
If you wish to try aGPS, feel free to do so, as it can be disabled as easily as it can be enabled, a hard-reset should not be neccesary.

I bought the HTC Touch HD a few weeks ago and noticed that the accuracy is not just bad, but atrocious. It can't even locate me within a 300 meter radius. Is that normal? Does anyone else have this problem? I am using the latest Google Maps.
Thanks in advanced.
I would try a proper GPS program and see if it is the same, if so your HD is faulty.
No problem here. .Maybe silly question, but did you click on "Use GPS"?

Are you sure you have a satalite lock? Google maps also determines position from cell towers and gives an estimate to your location within approx 500M. Once gps is activated and satlites have been aquired, a more accurate position is displayed (and i get a blue triange above the location - i guess to indicate actual position).
The little blue trianlge shows the direction you're moving - so the GPS is pretty accurate! Sometimes it doesn't get a lock for a while (it'll say at the top-right when it has active satellites) - if not, then it just uses that cell tower triangulation thing which gets it within about 500m as mentioned above.

Ya, it is on.
It can get working when I'm on the move, but as soon as I am still, it screws up. For instance, I can be driving to work and it works fine as far as telling me where I am at the moment. As soon as I close it and reopen it at work, it tells me I am somewhere 300-500 meters from work.
I guess I don't understand how it can work so well on the move, but as soon as I need an accurate reading, it is way off. Does this happen to anyone else?

Once it's closed it loses the "Use GPS" setting and you have to turn that back on and wait for the Satellites to be located all over again.
Well i think there is a gps delay issue with the latest HTC phones as blackstone, Raphael and diamond and i believe there is a little on the x1. Well there will is always ways to tweak settings in the registry i guess. well you'll probably find something here at xda...
Ok, I see what you are saying...sa we speak, I am trying to get the location of where I am at on my phone. The status has been on "Seeking GPS satellites (0)" for about 3 minutes now. It just relocated my location nowhere near me.
Ok, I just got a message telling me that my "GPS receiver is having trouble tracking GPS satellites." It's a very clear night in southern California, no clouds, no trees, etc...If it is because I can't get a satellite, is there a way to configure it?
Can it be because I am inside my house? If so, that is absurd!

Well i suggest you to go out and test it.. well also i suggest you to always keep your quick gps application updated so you'll get a quick fix locked to sattelites.. my Raphael locks on around 20-30 seconds and sometimes even less....
no problem here!
i've tested head to head with my old Asus P535 SirfIII (wich is pretty good as gps) on a 300km trip and they react in the same way.
no lag, no errors.
i use iGO8!
Well i found this on youtube: omnia vs HD in gps...
i am aware of that greek clip
what can i say? they have their experience, i have mine.
from my experience i say the gps of hd is good enough, as long as i don't make maps and i don't need precision on cm level
GPS works great on HD. Tested with IGO8 and latest TomTom, as well as Google Maps - all have accuracy within 5m range, wich is more then enough for normal navigation use.
I also tested my HD along side with Garmin car navigation unit - they were literary synchronized to the very second, even the voice instructions came at the same time, it was actually very funny
If you're having problems, I suggest you look up here on the forum for HTC GPS tool.
Well just to say, I agree with you guys eventhough i have a Raphael.. well i guess the gps chipset are the same.. (correct me if im wrong though) .. well many people in the Raphael community is talking about 50 - 100 yards lag but i only experience 5m, the most ive experienced was 10m but that was just once..
GPS doesn't work inside. Not just on the Touch HD but on any GPS device.
At the most, my lag is a car's length. I think my Trinity was slightly more accurated but not by much.
As far as getting a lock from inside, I can occaisionally get a lock if I am sat by my West facing window, but otherwise not a chance!
Ok, I got it working! I guess it just takes a couple minutes without touching any keys to acquire the satellites.
So in conclusion, to impatient people like me, don't touch any keys for a good minute or two. Thanks, guys!

Mine does. Can take about a minute/minute and a half to lock to the satalites, usually finds about 9 of them, and from google maps when zoomed in to max you can see roughly where abouts in the house the handset is.
The cell tower lock is useless. I'm in the north west of england. The cell lock feature keeps telling me I'm in Russia!!
like all gps i have used, sometimes getting a fix is hard work, regardless of apparent sky conditions.... i guess thats what happens when technology (the gps sats) are made by the lowest bidder
if you have a "your postion within 300-500m" message displayed, then that is using the cell mast to get your position, you never see this message when using GPS
some progs and some roms prefer to have the gps ports mapped, i do it manually for all my gps progs using com4 and bit rate of 9600k... seems to offer best situation
afaik, no civilian GPS can assure an accuracy of greater then 15m, although some units some of the time seem to be more precise
i dont see lag, i see the limitations of GPS (outside of military application... but then again, we've seen how accurate smart bombs are not!!)
My Gps on Google maps is tripping -=- tells me -=- location temporarily unavailable .............................
anyone else with this issue??

guys thank for ur replies ..i have the Vibrant & the GPS is working now... i did nothing to it ..but i am happy also be looking out for my wallpapers coming tonight for the VIbrant
I'm having problems with the GPS.
I have two G1s and got two Vibrants to replace them.
The G1s CPS lock easily and give you 12 feet precision very fast.
The two Vibrants take forever to lock and stay at 35 feet precision, sometimes going down to 30 feet.
G1s are miles ahead in the GPS department.
I'm dissapointed.
^ I'm not seeing those results and my Vibrant locks in quicker.
If you're going to compare it to another phone, then clear all of the google map cache before you start comparing.
My G1 and Vibrant took about 1 minute to fully lock on into my location and both were accurate. Sometimes the G1 is slower though.
Yeah maybr Cellular Data enables A-GPS instead of regular GPS. Not sure but now I get a lock in my house! Phones always suck without AGPS. 10 minutes to acquire a signal without it.
my gps has been snappy... interesting that there have been problems (compass has a slight jitter... but its almost imperceptible)
Nevermind Think I got it
i have yet to have GoogleMaps successfully find my location, both inside my apt and standing outside. My GoogleMaps updated itself this morning. Any tips?

This shouldn't be necessary. I know aGPS helps, but pure GPS should work anyway, albeit taking more time to lock.
I bought two Vibrants and left hem out in the backyard for 1 hour, over a table, and they could not lock on the satellites. One hour!
The GPS ship in these unites are either second class or there is a bad batch.
The old G1 locked in 15 seconds.

15 seconds without aGPS is better than a standalone GPS system. You must've had aGPS on..
@jblade1000 Yeah I didn't even think to check it. I think it was left off unintentionally by T-Mobile or Samsung. It works for me. We might not even have standalone GPS. It's not out of the question.
My GPS won't lock for the life of me. Thought it might be due to being inside, but I went out in the middle of a field and got no lock.

Worked perfectly after I did this.
Just to clarify for everyone:
Settings -> Location and security -> check use wireless networks and check use GPS satellites..
Well like everyone I had the GPS issue and it was frustrating. I do run an app killer and I always notice many apps (especially the preloaded ones) Keep launching themselves. It got rather irritating. Specifically Telenav.
I noticed with Telenav my GPS would be very flaky. Once I got "killed" it the gps seemed to improve. I thought to myself maybe I'm just being paranoid.
Did a bit of research and found an app called "Start UP Auditor" which completely kills an app and restricts it from every starting up again. My gps seems to be working much better now.
I drove a few miles and on the Verrazano Bridge here in NY and the GPS was super percise. When I was at the end of the block it was at the end of the block as well at the same time. Not like it was before.
Now I can launch google maps and it will find me exactly in front of my house and not 200 feet away.
Takes a solid minute to lock on. Not more but not less unfortunately. So there still is a bit of a problem but for me at least it has exponentially gotten better. Versus it not even locking on previously.
I think I might be on to something. I cannot give all credit to me because I saw on a Tmobile forum someone say that they think the problem might be with the self launching apps so that's where I started to draw conclusions.
EDIT: Scratch that one min thing. It seriously just now took me 10 seconds to lock on and the GPS to start talking to tell me where to turn inside my house. Issue fixed?
I completly removed TeleNav and I still have GPS issues... It is not any software causing this problem. It is a Hardware / Firmware / Driver issue.

Same here, one of the first things I did after rooting was remove all the bloatware, and Telenav was one of them.

Hmmm... Interesting.
My GPS issues seem to have disappeared after killing Telenav.
This just takes me back to the drawing board once more. I just do not understand...
I would like to see others responses. Does there happen to be vibrants with different firmwares?
So what happened to me?
Was it some magical stroke of luck?
Wow.
Initially, disabling TeleNav gave me a significant improvement in GPS performance. Indoors, I went from having 50-60ft. of accuracy (with multiple locks), to 12-15ft. of accuracy with a single lock. Initial accuracy was in the upper 40s, but quickly dropped to the highest accuracy I've seen with the device (the 12-15ft. figure) - indoor or outdoor - within a minute. Crazy.
Outdoor, on a perfectly clear sky, the best I've achieved was previously 25ft. of accuracy.
I rebooted (the phone froze, wheee!), with TeleNav still selected as disabled, and now, I'm only getting 30-52ft. of accuracy with a single lock. This took about two minutes to come down from 170ft. or so.
GPS settings have been switched to 'Automatic', from the stock supl server, for all of these tests.
Maps still shows me in Issaquah, initially (incorrect data), but quickly updates my position my exact location (within a few seconds). Previously, Maps would take at least a half hour to place me in even the correct city! Margin of Error: ~50ft. or so (shows me on the street, rather than on my property), within seconds.
Compass, as expected: still totally ****ing broken and ****ty.
I can confirm that - besides not being able to lock onto more than a single sat - I'm seeing drastic improvements. Thanks for pointing this out.
Still, I'm not sure the improvement will be enough to convince me to hang onto the device while we wait to hear from Samsung. :/

Yea like I said in the OP the fix is better but there definitely is a problem that needs to be addressed. That might be either hardware or firmware, All thats left is to wait for sammy to fix it up. However my GPS performance for my needs is more than exceptional.
I have noticed that while running GPStest, Google Maps starts to work. Something is wrong with the API.
If anyone is getting black screen freeze ups, disabling GPS will clear that right up.
And, we're back to square one. So much for that.
Location services can no longer locate me, and show that I'm in a neighboring city. Nothing I adjust fixes this for more than a short period of time.
Oh, Samsung...

I drove for miles and had nothing. Though if I am not using GPS I always turn it off to conserve battery.

And, we're back to square one. So much for that.
Location services can no longer locate me, and show that I'm in a neighboring city. Nothing I adjust fixes this for more than a short period of time.
Oh, Samsung...

I wonder if they can't even find the issue yet. It will probably be fix in the 2.2 update.
I removed TelNav within 4days of owning my phone and it really for me hasn't changed a thing.
What helped me was turning off the wireless location feature. From what I noticed it looks for your location based off the cell towers first then it looks for your location via GPS. If its slow to find you via wireless then well its slow to find you via GPS too.
I didn't really tried the GPS when I saw the threads saying there was a problem with it and I read somewhere about "how to fix it" so I applied the fix before even using the GPS before, so I have no clue if I had problems or not, but after the fix, the GPS locks in about 10 to 15 seconds and gest my location on the spot, even indoors.
just change the GPS settings to google servers
Directly after rebooting my gps/navigation seems to work much better.
To make it more clear... I'll be using my phone throughout the day and then i'll try to use navigation. Usually it will just keep trying to find the route but it never actually finds it. I'll reboot the phone and it'll find my location and the route in <10 seconds.

I believe the wifi and GPS share the same antenna. Anyone know which antennas do what for sure?
Our cellular antenna is at the bottom under the bump. The one at the top next to the antenna port does the rest.

If anyone is getting black screen freeze ups, disabling GPS will clear that right up.

Thanks for this tip, I hadn't caught this in the other GPS threads.
I ran and used My Tracks but forgot to turn on GPS. When I tried nav it could not get a fix until I restarted. Next time I'll try killing conflicting apps.

I just deleted the Tel-Nav app and now my GPS locks on in about 10 seconds and is dead on accurate. I even drove 165 miles today and never dropped a GPS signal. I could never do that before.
Does anyone know why the times are off one the gps sensors? My local time is 10:51, but gps test has it as 18:51 that is about 8 hours off.

Hi,
I've recently aquired a Google Nexus 7. One of its great uses, I believed, would be as a driving aid, w/ cached Google Maps or with an alternative driving/location app, such as CoPilot. But, after testing it for two days I see that the device can't get hold of a GPS signal at all.
What the problem seems to be:
- The device is stuck at "searching for GPS". It never actually gets a response; no GPS at all.
What I've tried so far:
- Resetting the device to factory settings -- since it's brand new and I only had a couple of apps installed, I thought that a fresh start would be a good idea just in case.
- Moving to various locations and checking whether it was a location problem. I've tried both "on the go" -i.e. in a car- and static. No GPS at all cases.
- Downloaded GPS Status. It's always at "Looking for GPS location". My longest record so far is 10 minutes of it -- still, no GPS.
- Checked with a couple of other apps just to see if I'd find more information related to the problem, none helped. It seems that if a GPS fix isn't found, they can't offer much help.
- Disabling Google's Location Services and disabling Wi-Fi access, in case it messes up with the GPS receiver. No luck.
- Rebooting the device. Nope, doesn't do anything.
- Using GPS Doctor's -a paid-for app- auto-fix and manual fix features. Tried aquiring a GPS signal for 10+ minutes, nothing happens.
- Leaving the device for more than 30 minutes under clear sky and more than an hour next to the window, trying to find a signal. Nada. No workie.
- Dancing naked under the stars next to twelve lit black candles. No luck, but it felt great.
Things to note:
- It's running Android 4.2.1
- I'm in Greece ATM, maybe this is a country thing? I'd bet against this, just pointing it out.
- AFAIK, the device hasn't aquired a GPS signal at all so far.
- The device is brand new, never operated before I opened the box.
- It has not been rooted, messed with etc. etc. at all.
Any ideas welcome. Thanks in advance for your help!
The reviews of GPS Doctor indicate that it MIGHT solve your problem. It's a paid for app at https://play.google.com/store/apps/details?id=com.epekware.gpsdoctor&hl=en

Thanks for the reply. Since it was only 1,5 euros I gave it a try -- no luck. After using both auto-fix and the manual fixes and searching for a GPS fix for 10+ minutes, it doesn't seem to work.
Sorry I've just re-read your initial post and saw you had tried GPS Doctor.
You've tried it outside. Is there any indication that signals are being received - satellite number and a bar graph that changes colour when a satellite has been "resolved". Is this a Greek model? - If it was for a different market then it may be that it is trying to resolve the satellites to give a location in the intended market (once a location has been fixed the GPS will quickly get a fix when powered up again within say 100km using the data it stores, the almanac etc you can clear in GPS Doctor). Before returning the unit I'd give it a try by leaving it with a view of the sky for at least 30mins

It's actually not your fault -- I've added GPS Doctor to my initial post *after* you've suggested it & I've tried it, for bookkeeping and so that other who try to help see at one place what I've tried doing so far.

Yep, I've tried it outside. It's a Brittish model, not a Greek one, but I'm trying to use it in Greece ATM. There's no indication whatsoever that it has resolved a connection to a satellite when I'm trying, so I guess it'd be reasonable to say that it hasn't reached one so far.
I'll try your suggestion. 30 minutes of straight satellite-searching it is -- thanks again!
*Update*: 30 mins doesn't seem to do the trick. I'll keep trying, then, until a better suggestion comes up.
There is an app called GPS Test or GPS Test Plus which will show the strength of each satellite signal received. My Nexus 7 often gets a lock inside a wood frame house but going outside with a clear view of the full sky works fastest. Hope you are not using a conductive case as the antennas are on the rear of the tablet.

Hi, thanks for the suggestion. I've tried GPS Test -it's under the "couple of other apps" that I've mentioned trying in my OP- but it seems that my Nexus 7 doesn't even get a satellite signal to begin with -- thus GPS Test displays no information.
I'm not using a case and I've tried leaving it for about 30 minutes under the clear sky. No signal at all. I have it by the window, ATM, just searching & on charge.
Okay, after quite some time out in the open sky and next to the window, I'm quite sure it's not about finding the time to contact satellites or anything of the such. The device simply cannot find my location.
Any new ideas?
Send it back if possible,sounds like a faulty GPS.
There are location setting hidden in accounts,see if they are on.

My problem with the GPS is that it will SEE the satellites (according to several GPS test apps), it just won't lock on to any - no matter how strong the signal or whether or not I'm indoors or out.

Hi, thanks for the reply -- do you mind sharing more info on this one?
Try faster fix, its free but requires root.

If Settings - Location access - location access ON and GPS checked yet you still receive no satellites then your GPS function is defective. Return it to the seller.
Same GPS issue with N7
Hi OP, did you get any solution for your problem?
I am facing a similar issue, I am trying to use GPS on a US bought N7 in India.
Is this a common problem, i have tried many gps apps, but none shows my location.
If your N7 is new and GPS never worked properly and your various location settings are correct, you might want to return & exchange it for a different unit as it could be a hardware problem, beyond any software or Apps-based solutions here. If you are using a weather app, does it find & use your location info?
I had a similar issues with GPS and eventually returned that malfunctioned unit locally to exchange it, upgraded from 16GB to 32GB unit as it was also having the random touch-screen key-pressed issues, etc. It either won't find the location and/or is off by a few miles to as much as a thousand plus miles, sometimes putting the N7 in the middle of the ocean, LOL. The new 32GB unit is flawless.
What I recommend is to try to download from Google "Play Store" - GPS Status by MobiWIA (v 4.0.1 is what I'm running on mine - has been using this for 2 years on multiple devices and it worked for us here - USA) Basically, it download & update, refresh and give assisted hand to the built-in GPS receiver - it run in the background and will turn on to track/lock on to various GPS satellites, inititially showing 5 to 7 sources indoor and at many as 8 to 12 sources within 60 seconds. Outdoor and clear view of open sky, it will lock faser & find more satellites. It is ad-supported and free, not a metered trial-ware
With a WiFi signal, Google Maps open quickly and zoomed it quickly to my locations in 15 seconds - very accurate and as good as when I'm using it on our HTC devices - same is true when I use Nav(free) USA - free off-line GPS software with preloaded maps as it does not drain the battery quickly.
I like the giant 7" screen for "cool" naviagation but until I'm comfortable with a solid & secure mount inside our Honda CRV, I'll stick with the smaller 4" screen of our HTC smartphone with unlimited 3G data access, as a drop will risk breaking the fragile glass lens that's prone to cracking.
similar issue but...
Had already tried Faster Fix (which gave error) and Faster GPS (which managed to reset GPS.conf) but still couldn't get Google Maps to lock in GPS. Was wondering if problem was GMaps or N7.
I googled 'nexus 7 can't get GPS lock' and ended up here. Decided to try GPS Status which showed everything working as it should ('copy location to clipboard' option lets you verify the location via browser). Went back to GMaps hoping GPS Status might help it along, but still got the same 'your location is temporarily unavailable.'
So not hardware must be software. Didn't have to look far checked 'other apps' in the GPS Status program and discovered Orux Maps, free. Upon starting and clicking GPS button didn't take it more than a few seconds to get the lock.
OP issue might still be hardware but thought I'd post here in case someone else ends up here.
i know its an old post but i am facing the same issues here! at the beggining i thought i have got a faulty device. Thats why i bought a used one and tested it before purchase live. The GPS was working just fine. I installed Cyanogen 13 opened GPS Status again and found Satelite. I thought everything was working like it should be. After 10 Min. i went to the car and drove to a friend without any issues. After 3 hours i went home again without any problems. But as the tablet restarted i never got a satelite signal again... always looking for my position.
I am pretty sure thats a software issue. Went back to stock firmware. Problem remains.
