GPS won't aquire Sats

When i first got the DX GPS was awesome...but it slowly got unreliable....sometimes toggling GPS on and off would resolve it, sometimes a reboot...but now no matter what I do GPS will not pick up. I have even tried pulling the battery...still nothin.
Any ideas?

check what kinda apps you have going on, some of the tweek with the gps settings, my parents droid, really sucked when they had weatherbug installed or was it the weather channel app, one of the 2 was notorious for destroying your gps signal in other apps.

I don't really have any apps that use the GPS that I know of... and I never see the little GPS icon flashing at the top unless I am trying to get it to work.

I had to check 'Enable Assisted GPS' for mine to acquire a satellite with Google Navigations. It's disabled by default, doesn't seem like it should be required though.

i9000m GPS: Working theory

So we all have issues with the i9000m and GPS (Or many of us do).
After I got my replacement hardware with a Dec date on it and when it was running 2.1 and was using whatever the version of Google maps was out at that time (Dec 24th), my phone was getting GPS lock really snappily.
After updating to JL2 of 2.2, it became unpredictable but when it was working, it was VERY fast. Two weeks later, my friend got his back and they had only replaced his mobo but he was unable to get a GPS lock in Google Maps or any Google app that used GPS.
Today, on break, after I had fiddled with my phone some this week, we tested what I was thinking of, that being: Google Maps or something with how it and 2.2 interacts is broke on our phones.
Here is what I did that was also tested and is doing the exact same thing on mine and my friends phone:
Install the Tricorder app
Reboot the phone (Either battery pull or power switch, same result)
Try to get a GPS lock in Google Maps (Our phones would time out to power save before it would get a lock)
Start Tricorder, go to the GPS/Compass section and wait for the satellite bars to turn blue
Exit Tricorder and then start Google Maps or any other Google app, the GPS lock will occur in less than 10 seconds every time
If anyone else could test this on the newer hardware or on a phone that had its mobo replaced, it would be nice to see if this is happening on more than these two phones.
And note that once I started and exited from Tricorder after it locked, all GPS apps now locked super fast.
Both our phones are running official JL2 2.2 with no rooting or whatnot.
Thanks,
Jason.

It is well known that you sometimes need more than 30 seconds (default screen off delay) to get a lock.
But if you start an application that can run in the background such as google navigation or my tracks (recording on), your GPS won't shut down when the screen turn off and you will finally get a fix if you wait long enough.
It is also well known that once you get a fix, if you loose it (by turning off your GPS app) you can get it back really quickly.
You didn't find anything special. Just leave google maps open (by pressing on the screen at least once every 30 seconds) and you will get a lock just as fast as with your tricorder app. There is no magic. You only need to leave your GPS on for long enough.
From my experience, I sometimes waited 2-3 minutes with JL2. But I don't care, as long as the GPS is accurate.

I have exactly the same lock on with Eclair > JPY > JPX > instant to about 30 seconds .
This is about the hundredth supposed fix posted .

Very well...
I shall fade back into the shadows...

And how is waiting in Tricorder for a GPS fix instead of Google maps a solution?

Exactly zorxd..

ok, so what if since either (can't say for sure cuz don't use gps much at all) rooting, or flashing speedmod k13e, when i pull down the tool screen and click on gps to turn it green, the gps icon does not appear at the top of the screen - i don't think it's on at all. apps like maps, gps navigator etc that use the gps don't work.
what's that about?

Newest Version of Google Maps Locks Location Slow, Other Apps Fine? Anyone Else?

Anyone else experiencing this issue on their S4? The newest version of google maps (with the new layout) is painfully slow in locking my location, often taking 30 seconds to 1 min or more. Other apps that use location data (uber, gasbuddy, yelp, etc) lock very fast with a-gps (i usually have gps turned off), typically in 1-3 seconds. Google maps though, the most crucial one, takes forever. Often I will open the app, and it always default opens to the last location I was zoomed in on. I will then manually move the map to look at something else, and 45 seconds later it finally locks on to my position and zips away from what I was looking at and to my physical location. Really annoying, and since the other programs seem to work just fine, I am assuming this is an issue with the maps app itself and not the gps or a-gps capability in the phone.
Anyone experiencing the same issue?

Not really. When I have GPS issues on Maps, I clear its data/cache, and reset my GPS data in "GPS Status" app. Usually that fixes things. But each case is different. Start from there, see how things progress.
My main issue since day one has been the orientation of the marker on Maps. On my old S2 with the old Maps, the map oriented towards the direction that I'm driving. Not in the S4/New Maps combo. I click on the "compass" icon, doesn't orient it properly. I've calibrated my compass. Still the same. Annoying. Not an issue in Navigation, only in standard Maps.

This appears to be a different issue as clearing data/cache has no affect, and it mostly refers to the a-gps locking location. It is equally slow with gps, but I never turn gps on and in the previous versions of maps and on previous phones, a gps worked very fast to lock a rough location. It still does with other location based programs, but the new maps is the issue I am 99% sure

GPS stops updating/turns off after a few seconds

A few times in the past couple days, I've noticed that a few seconds after opening maps or an app like gps status, the gps symbol in the status bar simply disappears and the app I'm using stops updating.
I thought it might be a problem with maps until I caught it doing the same thing on the gps status app (and the gps test app as well). So it doesn't seem like an app problem. I have location accuracy mode set to high under location settings, and no power savings type modes or apps running. I have the at&t version of the s5.
Any ideas what's going on here or how to fix?

This is driving me nuts - it hasn't happened to anyone else? It seems like it generally happens when the GPS is 'cold' - like first thing in the morning. I'll open maps, or try to navigate, or one of the gps apps, and the gps indicator in the status bar simply turns off after a couple seconds and whatever app I'm in stops updating my location. If I close and reopen one of the apps, it'll do the same thing again. Eventually, after say 3-10 times of this - suddenly the gps status indicator will either stay on or might come back on a couple seconds after having turned off. After that, it seems to have 'warmed up' and works normal even after closing/opening apps to test it. I've also tried clearing maps data, as well as resetting agps data. Anything else I can try short of a factory reset?

GPS issue - satellites in use, but no position

Hi everybody.
I have SM-N9005 phone, currently running Temasek V16.0.
My GPS usually works fine, however sometimes it finds the satellites and uses them but doesn't get GPS fix for a long time (actually - never, as far as my patience go, which was about 15 minutes). After rebooting the phone the GPS fix is almost instant, with no problem.
So, what can cause GPS to be unable to get a fix, while it can use the satellites. Seems to be software related as reboot makes it fine. It is not ROM related, cause I've had it on stock as well as custom ROMs. Anybody can think of a fix that doesn't require me to reboot?

No, I have given up on GPS of this phone, Snapdragon variant. As you said, rebooting the phone makes the GPS lock fast/ instant, but for normal usage sometimes GPS just won't lock. All I can gather from my personal experience is its about Assisted GPS. When you are restarting your phone the AGPS data is being downloaded automatically, that is how Android works anyway, and that's probably why the phone gets a super fast lock after a reboot. Use app like GPS Status or something to have the phone download AGPS data at short interval, see if that helps in anything or not.
However I have never had any problems when I am outside, the GPS locks within 30-45 seconds no matter what, its the inside problems which used to bug me, but as I said, I have given up.

Hm, I've never seen such a problem. I use my N9005 for travelling across Europe quite often, and it usually locks within 10 seconds to 2 minutes, depending on the location and the number of satellites.
Aside from the occasional glitch, of course. Like going backwards or sideways. :silly:
And it seems to think I'm somewhere off the coast of Norway right now. That one creeps me out quite a bit...
The thing is that when you reboot, it uses all available connections to pinpoint your location. Including your mobile data. (And WiFi if available.) So if you turn on location services right after rebooting, your approximate location is still in the cache.
Triangulation Over Data works within seconds, as opposed to the time required to lock on to the satellites in orbit when it is only allowed to use GPS. If you turn on the higher location modes, it locks much quicker. You can turn it back to GPS once your location has been established.

I am talking about GPS only. I use GPS Status app for a long long time (with my previous Android devices as well), so I can monitor the GPS fix. After reboot I get GPS position almost instant or sometimes I need to go into GPS status app and re-download A-GPS data (which is max 1h old, because of my settings) and then I get my fix.
When my problem occurs NOTHING (short from reboot) can get it to get a fix. I tried deleting and downloading A-GPS data, turning location on and off and from high precision to power saving - it just won't work. Of course I'll get postition from WiFi or cell towers, but GPS just won't fix, even with 12 satellites in use, after waiting over 15 minutes (which should be more then enough, cause whole GPS almanach is transmitted over 12,5 minutes and I get it from A-GPS anyway).

I would start by wiping the phone installing stock rom and testing . Still a problem then its hardware .
