[Q] GPS problems. Can't get a fix!

Hi all,
I have the Desire HD for 2 weeks now but I've only yesterday noted the gps doesn't seem to work... It's a complete stock model, no custom roms or radio's. I'ts just never able to get a fix! Are there other people with problems like this? Could my device be broken?
I have installed a app from the market that tests the gps and it finds no satelites most of the time except one time I checked it found 4 with a very bad signal... Even then in Google Maps or the HTC Locations it didn't get a fix.
Any ideas?

Bump! I have exactly the same problem. Any Advice?

same problem

i HAD this problem, but then i left the GPS on for an entire journey. 45 minutes later it had a fix and ive never had any problems getting a fix within a minute since.
i dont think the phone knows what side of the globe its on the first time, so maybe it just needs a loooong time the first time.

Most GPS devices need to download a file known as an almanac. This determines where satellites will be at specified times.
This file can take a while to download as GPS is purely passive. I'm not sure if the DHD is A-GPS (Assisted). This will download the almanac via mobile or wifi data.
This is why sometimes the first GPS lock can take a while.

Try these two programs:

http://www.appbrain.com/app/gps-test/com.chartcross.gpstest
First one is great for diagnostic so it should tell you what is wrong.

I also have the same problem, been driving for about 30mins and nothing..

1st gps-fix is a pain, after it will all get better....search for my posts, you'll see that this has been asked several times (don't want to be a b**ch but, please use the search button as well) and in general, 1st fix takes some time, 2nd is fast (like <2 min).
At this moment, while I thought my gps fix was very bad (and as I own one, if not the, of the 1st DHD batches, it was not abnormal to think that it also had gps probs) it now fixes within 1 minute....

Problematic piece of device for me for GPS.

Got mine a cpl of days ago , downloaded the apps above but still nothing i will give it one more try.

I tried both GPS apps. And immediately after that, I was able to get GPS satellite lock on within 20s.

Guys regarding the GPS, all of us we face an issue. It can not lock the satellites quickly. Especially for the people like me who are HTC HD2 owners as well. I was waiting only few seconds. (cooked rom). We MUST forget that now. It's an issue for all of the android devices. Even with the device of the Nexus. So we must live with that. Sometimes it will lock the satellites in 1 min or 30 secs, some other time in 2-3 mins. I searched also in the internet and i found so many complains regarding the GPS and hopefully not only from DHD users

Yep, I had also that problem but then red at forums that only way to lock as fast as you can satellite is to use first one for locking over internet and after that it's much easier to find satellite. Whenever you have problem with locking or need gps asap first program should provide you with fast satellite find.
Btw gps on dhd is so good that I have sold my old garmin - simply it's obsolete and now I have only to purchase official car holder.

Most of the times is more difficult to get a fix in a speeding car.
In the opposite case is generally faster to get a sat fix.

So I've been using my DHD for 3 weeks now (stock model as well, no root) and here are two issues with GPS that I noticed and have no idea what to do with it.
1. The same problem as described in first post. Every once in a while my GPS just cannot get a fix. I installed GPS Test app. Normally it finds around 6-7 satellites, they are all in use, the yellow indicator in GPS status bar goes green and my location appears on mini-map.
However there are situations when GPS Test says that there is 1 to 5 satelites in view, later on they also apper to be in use, but GPS status doesn't change to green and my actual location doesn't show. It's not a problem of visibility or my location - the GPS can get a fix today and not work tomorrow at the very same place.
I have no idea if this can be fixed, so any help appreciated.
2. This is not really an issue, just something that I find quite disturbing. I'm using this traffic app (Yandex Maps for those of you in Russia). It shows current traffic condition on the map + your current location if you have GPS. So each time I lock my DHD (press the button on the top) the GPS is immedietly switched off. So when I unlock the screen to see the map again it takes from few seconds to a minute or even more to update my current position. Sometimes it doesn't happen at all (see problem #1). I understand it's probably done to save battery but I would prefer continuously working GPS than saving battery. Is there any way to set GPS to always working mode?
Thanks in advance to everyone who can help. Cheers

Hi,
I read all you guys said and after trying both the apps and refreshing my agps data manually I now get 6-7 satellites which is good I think?
So for all of you with the same problem, just stay outside for a moment and make sure you have a data-connection. Then use the GPS Status app and refresh your agps data manually. It should work... It did for me!
Ps. I think my Desire, not the HD, used to see 11 satellites? Is that possible? Does this mean 6-7 is kind of weak?

Just to make it clear - to manually refresh AGPS using GPS Status - you need to go to Menu->Tools->Manage A-GPS state->Download?
I'm not outside now, but will try it once I have problems getting a fix.
And yes, 11 sats is possible. 6-7 is more than enough though.

Stand still to get a fix? Harder when you are speedy, I think.

Your movement speed has no impact on how quickly you get a lock. Remember, these satellites are in orbit traveling alot faster than your 30 - 70mph.

[Q] Is MY GPS problem typical?

First off, I'm aware this phone is riddled with GPS problems, so I'm not asking the typical questions. But pretty much everything I hear from people about their problems are how they never get a lock, or it takes several minutes to get one. That's not my problem.
My problem is after I get a lock (which is usually pretty quick) and am driving following my Google Nav directions it will CONSTANTLY lose the satellites. Seems to be every couple of miles that it starts searching for satellites for about 2-5 minutes before refinding them, only to lose them a few minutes later, and usually right when I need to exit the freeway. Also it takes it a good minute or so to realize it's lost the satellites, so it will keep me frozen in the same spot on the map for this time, not giving me the convenient button to access the list view.
Has anyone else experienced THIS specific problem, and do you have any advice?

What android version are you on? I had problems like this on eclair but my GPS on froyo is as good as my wife's evo.
Sent from my Evo Killer!

Froyo, Quantum 2.5. In fact this problem has really only been since Froyo ROMs. My GPS was solid in Eclair.

So... nothing? Not even a "no, nobody's having your problem?"

I've had this problem from time to time, but it seems to be inconsistent; I use google nav a few times every day. Hasn't happened lately though and I've been on the same ROM for 5 days now.

I have this issue and i'm on the latest bonsai rom. I think it is a problem with Google Nav personally because with Sprint Navigation it happens less often for me. Or Perhaps I just have a bad GPS chip. I'm going to run stock di18 for a few days and see if it is just Froyo and my Phone that bugs out. Maybe it is just my phone and I need a new one.

Yeah remember google nav is still in beta form
You're better off using sprint navigation
I never lost a lock and I'm on froyo stock dk28
And sprint nav is free..I can see why people on tmo and verizon use google nav but not sprint folk lol

Happens to me all the time (bonsai 1.1.4).
A quick work around is to use the GPS toggle in the notification area.
Disable it long enough for it to say it lost GPS, enable it finds it quickly (for me), but it's hella annoying.
=]

Update from my previous post,
Google nav worked for 20 minutes all the way home yesterday and today on my way to work it dropped out after 5 minutes then worked for another 15. I'm pretty sure this is just Google nav being buggy and Epic GPS internals are not the greatest. All in all Sprint Nav seems to be working a lot better. If you still continue to have problems try getting a replacement phone from sprint. I hear that some of the epics out there have better luck with GPS. You Could have gotten a bad one like me. WHen i've asked this question in the past on the forums a lot of people just have the big issue of not getting GPS Locks. Never see to many having the GPS drop signal issue. Everyone else's post that i've read say they have perfect GPS. Its funny because I get locks instantly but gps drops randomly like yours... so so lame.
Also try out the new Bonsai4all rom because after I've installed it i'm having a lot less GPS drops with Google Nav and i'm still testing Sprint Nav. Good Luck.
EDIT: I have been testing GPS driving to work and back home. Not one single GPS signal lost. This GPS issues might be in the past. I'm not sure if its Mammons Bonsai Rom that fixed it but If I were anyone having the same issues I would try a fresh wipe of your SD card and Odin epic back to di18, get gps signal in Google Maps, Odin to dk28- get signal in Google Maps, and CWM3.0.0.5 and then flash BOnsai. Good Luck

I don't know what is in bonsai 1.1.4 rom but my gps is perfect now and it was buggy with every other rom I've tried on dk28. I've tried a lot. Midnight,viper,epic experience.

I had this problem all the time. It was especially bad last week when I was down in Tucson for work. It was what finally motivated me to get rid of the Epic.

I have the same problem OP. I actually finally just posted about it today, see http://forum.xda-developers.com/showthread.php?t=921935 and my post is #4. I still don't have a solution, but am willing to try Bonsai 1.1.4 if it would fix things...
Such an annoying problem. I haven't been trying Sprint Nav lately as it is removed in Nebula 1.0.6, but I could try adding it back in and seeing if there is any improvement...

Try the phone reset with the msl code also. Many people are having luck with it. Good luck.
Sent from my SPH-D700 using XDA App

Had the same problem for weeks. So do many others, as this is on numerous threads throughout the boards (and Android Central too). On the latest Bonsai Rom (and others based on it like Midnight), they list a gps fix. Using Midnight 2.9 fixed it for me.
Also, when I was having problems, Sprint Nav worked much better than google Nav.

The more this happens to me, the more I think it's a Google Nav problem, not a hardware/firmware problem. When it happens I see that the GPS icon in the notification bar is solid and not "searching" for a signal. That to me points to the software as the problem. Either way, it's REALLY annoying.

I was never particularly happy with the Sprint Navigation app which is why I've avoided it. Google Nav always worked so well for me before. Also I've been trying to cut down on apps on this phone, especially carrier crap.
I may try Bonsai, although I've generally liked Quantum well enough that I didn't want to switch camps. Several people stating they're using it and not having this problem is a good trail to follow, though.
Still, pretty darn frustrating.
EDIT: All right, I just switched to Bonsai. All I can say is thank you for giving me the push to switch. I don't know about nav yet (although Maps lock was quite literally instant instead of the several seconds I wasn't too bugged by before), but the overall kernel is so absurdly faster I'm shocked. Thanks.

Here is what happens to me. I can get a very accurate GPS lock easily. When I am navigating, however, the GPS lock drops after a few minutes of use, as if GPS were turned off. If I have just rebooted the phone, the GPS lock lasts about 15 minutes, and then it happens again. I can toggle the GPS on and off from the pull down menu to fix it temporarily. But, it keeps happening, and it gets more frequent. I've been this problem on every Froyo ROM I have tried . . . Bonsai, Nebula, etc. It is NOT only on Google NAV. It seems to be even worse on NAVIGON.
I never had these problems on Eclair. The fix on Eclair was not as accurate, but it never just dropped.

This only happens to me when I lose signal. Which usually means I'm out in the middle of nowhere and need my gps.
Thinking of getting a back up offline gps for this reason.

This is not my issue. I am in the middle of strong 4G coverage when it happens + Navigon works offline (when you have a sat lock).

I didn't have issues before switching to DK28/Froyo/Nebuls 1.06, but now the GPS is awful ... even after doing the MSL reset. Frustrating is an understatement.

Reasonable GPS lock workaround w/o root

I've been having the same trouble as many have with the Epic 4G Touch's GPS. It takes forever, if ever, to get a GPS lock. I can have a GPS lock, go into McDonald's and come back out and it will be cold starting again. Ridiculous performance.
Rebooting the phone is a pain but seemed to be the only thing that worked every time. After reading a lot of different forums about this problem, I noticed a conservation that speculated that the problem wasn't specifically the GPS itself, but rather was location services. Apparently there are some more recent location services being flashed to phones and the GPS works great. It would make some sense that this is the problem because after a reboot I would think that the phone would reset location services when it turns back on. Further comments in those threads suggests that turning the phone to airplane mode and back also works around this problem.
I've been playing around with this for awhile today and it does appear that going to airplane mode and back helps the situation. I used Tasker to create a task that does this: turns on airplane mode, waits 20 seconds, turns off airplane mode, then launches GPS Test automatically. I created a widget icon for this task. I never attempt to get a GPS fix indoors. What I do is that when I walk outside on the way to the car I hit the widget. I let the phone do it's thing and by the time I get in the car and ready to go, I've had a GPS lock every time today. When I get in the car, I close GPS Test and start whatever app I want to navigate with.
So far, this method has yet to let me down. We will see how the weekend goes.

That's very interesting, I'm gonna try that and see if it helps. I also noticed that getting a lock by starting Navigation right away is almost impossible. It always helps me to Getty a lock with another app first. Telenave seems to work best for me.

This (among the countless others) workaround is fine and I thank you for it.
However I'd really like to know just what the hell is going on with the gps on these phones.
Some folks are fine with the gps working fine in any circumstances. While others have to wave dead chickens and performance some sort of incantation to get gps to be even reasonable. Still others have some issues but can work them out via flashing of modems and what not. Some had to replace their phone with another e4gt and it was fine there after. WTF?
The gps on my old GS2 i9100 was awesome. I never had to give it a second thought or worry about it losing gps lock or taking eons to get even a meager lock. This is entirely not the case with my current E4GT. Damn thing. If the update doesn't fix anything then I'm gonna replace it.
Is there just a batch of bad hardware out there? Is the gps sleeping when it shouldn't? Why does one fix seem to work for one phone but not another? Talk about manufacturer inconsistentancy, geez.
Does the sprint version of the galaxy nexus have these sorts of issues?
Heavy sigh.

Try GPS Status, it's available on the market. I just got a lock on 8/8 satellites within 5 seconds inside my apartment.
Google maps seems to take a little bit longer obtaining a GPS lock but after running GPS Status it seems much faster.
I believe that it does not require root, and the best part is that you do not have to flash back to GB, to get a lock so that you can flash ICS again.

I'm blue in the face over this issue. Invariably, you get "I get a lock on 12 satellites from my concrete bunker 12 feet underground" responses (not helpful, BTW), yet I can't get a lock in the wide-open spaces. UNLESS, I reboot, start up GPS Test or GPS Tracker, or bounce back and forth from airplane mode, murder a chicken, or whatever.
It's totally hit or miss with this device. Yes, I can get a GOOD lock indoors, but only after I reboot, run GPS Test, and then go back inside. Not exactly convenient when you're hurtling down the freeway at 70mph.
It's frustrating to hear of the great experiences of other users when my experience has been so inconsistent. I rely on my GPS for directions, and for tracking my morning runs. It's a real pisser when it takes 4 minutes for the GPS to finally lock, which ruins any useful statistics for Runkeeper.
I know this is just a rant, but at least I feel better.

Try what I mentioned with GPS Status from the market. It might not be a permanent fix but it will help with getting a lock on your location.
1. Download GPS Status from the market.
2. Turn on GPS.
3. Open GPS Status.
4. Bring up the menu and select tools.
5. Manage A-GPS State.
6. Turn off GPS from the toggle in the status bar.
7. Select the option to Reset.
8. Select the option to Download GPS assistance.
9. Close the application.
10. Turn GPS back on and watch it lock on.

I agree, after all my research and attempts at fixing my phone; the only option left to me is replacement. I'm tired of reading forums about it (yet here I am) and it's whole thing is just silly.
I don't suppose you have any documentation on the serial number for the phone that had a ****ty GPS? It would be awesome if there could be some sort of documentation of which patch of phones is bad.

Nexus 7 LTE Deb Multitouch and GPS issue

Hi anyone experiencing multitouch and/or GPS issues?
My friend is in Canada and just bought one for me. She's coming back to Singapore in 2 weeks and is helping me test it first in Canada. The unit prompted to update when started up which she did. I'm waiting for her to reply me what build it is at now.
I told her to download the Yet Another Multitouch Test and she tried dragging her fingers around. With a single finger a red blob follows her finger around but sometimes a blue blob appears right next to it briefly. With 2 fingers, when she was dragging 2 fingers around a green blob appeared a few cm away once. She did say she noticed sometimes using it normally that it was a bit unresponsive/slow.
For the GPS, I wasn't sure how to test it. I got her to use either maps or GPS Status and Toolbox. The first time she said it looked like the gps fix was ok for 45minutes (in maps). She DID NOT REBOOT and it managed to relock. The 2nd time was on GPS Status 18 minutes. The 3rd time the fix lasted for 19 minutes. But after that one, the 4th time it couldn't find a lock even after waiting more than an hour. She was testing it indoors so I asked her to leave the gps status toolbox on while driving to have a better test. Anyone experienced this? I thought that the GPS issue was such that once you lost the status, you couldn't get it back without reboot. But my friend said the relock was successful at least twice (indoors).
I also told her to try clearing the AGPS data and refresh data using the GPS Status and Toolbox, she will try that later.

I had the GPS issue that was fixed with a software update. Prior to the update, when I tried to use Waze or Google navigation, it would lose the GPS lock within 15 minutes, often sooner. After the update, I have never lost GPS lock during navigation. My longest drives are about 2 hours. Tell your friend to test it during a long drive, but if you got the software update, you should be all set.
I can't comment regarding the multi touch issue, I haven't noticed any such problems on either of my N7 tablets (WiFi, and LTE), and haven't tested for it.

multitouch problem seems very common, since I have read a lot of complaint related to the touch screen, I checked my screen as soon as I got it , and tested with Antutu which is a universal test tool, the result was frustrating as well-- UPPER PART of the screen functions insensitively compared to the lower part. It is a hardware malfunction clearly. What the hell did Asus react to it? We'll wait and see.

Well update..my friend brought the nexus 7 out for a drive. Just a normal journey, not a long one. Am I right in saying the ones with problems cannot relock without rebooting and if mine can relock without reboot it means it's got normal working GPS?
Also, the build (after the initial update) is JLS36C. Which according to this Deb thread: http://forum.xda-developers.com/showthread.php?t=2448352 should be the latest I think.

GPS slow initial fix with 4g on

Hello,
I have this strange problem with the Samsung A50 given to me by my company (this to say that my possibilities to mess around "under the bonnet" are quite limited).
The first GPS fix from a "cold" start (that is, at reboot or after some hours from last use of an app using location) is EXTREMELY slow. It may take also 10 minutes or more, in full air and with good weather. If I control with the app GPS Status and Toolbox (or similar apps giving details on GPS sensors status) the phone "sees" a LOT of satellites, up to 20 or more, but none of them is fixed, they all are "yellow", and the location is not set.
When it finally makes it, one way or another, then the fix is stable and even if lost, it gets re-fixed soon in some seconds... For an hour or two.
Naturally this makes most app using GPS highly frustrating to use - Before running with Strava or navigating with Waze I have to wait 10-15 minutes for the GPS to fix! Google Maps is somehow an exception because it uses the Google "fused" location which, though not as accurate as GPS, allows nevertheless tp have an approx lpcation pretty quickly while the GPS makes its slooow fix.
But now the strangest thing: if I reboot the phone without SIM cards inside, the GPS works like a charm and fixes satellites on a matter pf 30 seconds max! Moreover, if I turn off the 4g on both SIM and then reboot the phone again, also it all works well. I tried multiple times and this cannot be a casual result. I also tried making a a full reset of the phone: the behavior is exactly the same. Seems like something in the 4G system causes some software conflict with GPS making it crappy.
Firmware is the latest (SH2 sept 2019).
Am I the only one? This looks to me definitely a software issue, not an hardware one, do you agree? Do any of you have commwnts, suggestions, ideas?
Thanks

Looks like I'm the only one with this issue?

And what about on wifi? Did you tried this?
The only thing that i can think of is on 4g probably it struggles to get agps data from the internet (probably cant connect to servers) but not trying to receive the data from the satellites themselves because it think it can get it from the internet. This is just wild guess.

I just tried getting GPS via cell data while taking a dump (inside the house), the GPS lock was instant in Sygic, also 15 satellites locked on.

I am having this same issue with an A50 I just purchased. I use GaiaGPS quite a lot and it works horribly on this phone. My tracks are a total mess. To the point that it is not usable. I will be returning the phone (if I can) if this issue is not resolved, as it is a key feature for me.
