[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..

Ok......DHD has A-gps as well
seeing your posts, quite amazed how you did not know this (no pun intended)

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.

Navigation, "Searching for GPS" constantly? ? ?

When trying to use google maps & the built in turn by turn navigation it will load up then just say searching for gps & it never locks on & doesn't give me the voice guided turn by turn anymore. Google maps is up to date, gps is on & showing in the status bar, & I have tried in numerous locations with the same result. Am I alone on this one?

This has happened to me a few times with diff ROMs even. GPS test app shows that there are sufficient sats in view but the system never locks in. Next day it works fine.

Could be radio or kernal related. Try clearing data and cache. Probly wont help but can't hurt.

Do you open maps first then navigation? For some reason, when I open just navigation, it will do what you say and never lock on. Get to navigation by typing the address in to maps and then hitting driving navigation.

does the same in mine no matter what... i dunno what to do. running incredibly re engineered rom (newest one)

Driving around while trying to get a lock can cause it to take a little longer... Cloudy skies can do this also. Being inside a building can also interfere.
If you just have standalone GPS turned on, well that's your problem right there. The other two assist in getting a GPS lock alot quicker. The other two that I'm talking about is Google's and VZW's Location Services. Those two will also help get a better and more precise position aswell.

NOTE: Navigation. If this was a fresh/wipe install or you get stuck at "Checking Navigation Availability" do the following:
1) Turn on GPS
2) Start Maps
3) When prompted turn on WiFi (do not need to connect to any)
4) Map should then show approximate location
5) Get out of maps
6) Reboot
6) Start Navigation

I think this stuff is all on the right track. Here's my method (I get the same thing on a de-sensed stock rom):
I think Google Maps has the ability (not so great) to 'block' itself via using huge amounts of resources whereas the GPS doesn't use much resource and needs a helper app to get itself oriented the first time. Once oriented it is fine.
The one I use is a free market tool called "GPS Status" by EclipSim. It takes ~3 seconds to get a fix. So you start GPS (via power widget settings, whatever) and start GPS Status, wait a little while and you can see it locking onto satellites, and when it says first fix = ~3 seconds or ~30 seconds, (it depends on some unknown conditions), then close it and you can use navigation because it knows where it is.
Worth a shot. I've been doing that since the 'dawn of droids'.

I completely unrooted my phone and no matter what I do it will not get a GPS lock. I deleted Google maps and redownloaded it, uninstalled updates, tried every combination of settings in location, etc. and nothing.
I tried on my wife's stock incredible also and it immediately locks on to her location and starts the turn by turn navigation without any issues.
I think there was something wrong with the internal GPS chip/locator in the phone itself. I contacted Verizon and they are sending me out another replacement. Hopefully this one works properly.
Thanks for all the replies guy's but it looks like the phone is just defective.

read on another thread to wipe dalvik cache. So I tried it and it works. After initial wipe, GPS quickly acquired satellites and locked on.

[Q] CM9 on HOX; no bluetooth, no GPS, apps crashing

Hi guiz!
I installed CM9 on my HOX. But besides the known bugs with that, i also have issues with the bluetooth and GPS software.
Bluetooth simply wont turn on; when i pull/push the slider it keeps going back to 'off'...
GPS wont turn on either; when i open any form of navigation it keeps saying 'searching for gps signals', and the little icon in the top bar doesn't show up. and yes, i have turned on the internal GPS in the options
although its not like i can test with a bluetooth gps now can i ^^
A lot of apps crash, too. Could be instantly, could be after 20 seconds, but they all crash with the 'has stopped working' or something alike. Kindof hard to use the phon this way. Stock rom didn't have those issues in the brief time i used that.
I can't ask this in the CM9 [WIP] forum, being a newbie and all. So I hope someone here can help me? Is my HOX different? Why it no work!?
Oh yeah, i have the international HOX, so the Tegra 3 one.

Nobody has any idea's on this? Flashed the kernel again, uploaded the new CM9 alpha 7. Still the same errors. Crashing seems less often; but still not bluetooth nor GPS :/

[ION] Phone freezes after turning on GPS (ICS ATT ION)

Recently, I noticed that my phone always freezes after turning on GPS. Right now, I am still running it on 6.1.E.3.7.
I've tried several apps as well as GPS test in service menu, the results are all the same, the screen blacks out and phone automatically restarts..
I've also purge the GPS assistant data, no use..
However, if i open GoogleMap with GPS off and then turn GPS on under the request from Googlemap, "this app requires GPS service blablabla..", the phone won't freeze.

have you had this problem only on 6.1.E.3.7? (if yes then proceed)
i suggest you update or rollback to another update, it may be that that version is causing the crash, it may be fixed in a newer version if avaliable

Google Nav crashing with flashing white/black screen

got an issue with the google nav app crashing on me.
a little background first though.
had this issue on the std rom, and tried flashing the current ARHD 31.3 rom in the hope of fixing it, it hasnt!
from a fresh boot, i can go into the google maps app, choose a location and then use the nav app go to there, no issues at all.
next time, i open maps, no issues at all, choose my location, and as soon as i hit start navigation, the nav screen opens, showing the next turn to make at the top, the voice is telling me where to go, but the main map screen, is flashing black and white.
it flashes like that for 5 or 10 seconds before crashing, the only way to restore navigation to a working state is to reboot the phone.
its getting rather annoying now, as i dont use the nav very often, i tend to need it occasionally, and its irritating to have to reboot the phone just to get the nav working.
as far as i am aware, the GPS works fine in everything else, (Maps, strava, gps test) it just seems to be nav thats causing the issue.
i've already tried clearing the cache from settings, apps, clear data, but i still get the same issue
any ideas on what might be causing this
cheers

Had this too on CM, thought it had something to do with the ROM but after reverting to stock exactly the same issue. You're not alone
http://forum.xda-developers.com/showpost.php?p=46517908&postcount=15438

Any update on this issue? I have exactly same issue on stocked One X with Sense 5.0, Android 4.2.2.

I have exactly the same problem. I'm wondering if it's a Sense or app issue. Either way, I submitted a bug report.

I turned off the hardware overlay in the Developer section, and it seems no problem anymore... Not thoughtfully tested yet, tho...

Still flashing and crashing HTC One X+
Google maps to navigation is still flashing and crashing - even after turning off hardware overlays.
Works 1st time after reboot. If I swipe the app away from recent apps screen, then it starts failing.
3rd time I start it, working again, but I figure it's going to happen again.

Anyone ever get an answer to this? Last post I found was December 2013 and still nothing.

I think I've found a kind of workaround to prevent this problem.
When you search the location you want to reach, and you are faced to the tile with these info:
8 min (3,1 km)
some info about trip
[MAP]
Start navigation
Instead of click on "Start navigation", click on "8 min (3,1 km)", then when the map is open, click on "Departure" and maps should not crash.
I hope the explanation is enough clear, I've translated texts from the italian app so I'm not sure if I've did it in the right way.

Totally works! Thanks!
HTC One X
Cyanogen 10.2.1
I was so annoyed with this...

I have had this problem for the last year using the stock, rooted AT&T Rom for my HTC One X + My wifes phone that is an HTC One X does not seem to do this. I found when I removed the maps update it worked well. When it updated it seemed to work a few times then the flickering and crashing started up again.
I tried the other suggestion above.
Finally I noted that when I clicked on start nav and as soon as it tried to open the map if I hit the power button and waited a second and turned it back on the image was stable. Sometimes I couldn't catch it before it crashed but if I did it would do the trick.
Why doesn't google fix this?

Same here. One X with rooted stock ROM.
When the flickering starts, i turn off the screen and then back on. This works for me in most situations. Still really annoying.
