[Q] can't get GPS to work properly

I keep having problems with getting a gps fix on my DHD.
I turn on the GPS on the phone, also setting it to checked in the "Location" settings, and I wait forever. Yesterday I tried using the Compass app (By Catch.com), the GPS Status app, Tried using My Tracks and RunKeeper, and couldn't get a fix.
Every time I go back to the "Location" settings, and check and uncheck the "Use wireless networks" box, and also turn on or off the WIFI radio. But nothing seemed to work.
This morning I tried again, set My Tracks to record the road, and it did get a fix after about 5 minutes - So sometimes it does work.
I did manage to get fixes at various times, using all the apps above, but most times I need to fiddle with it quite a lot before it works, by checking and unchecking stuff. Sometimes it finally gets a fix with the "Use wireless networks" checked, and wifi turned on (even on locations where I have no wifi), and sometimes when its off.
Using the GPS Status app I see it usually finds 8-11 satellites, and they all seem green and with high bars, but I get no location at the end. Also with the Compass - I can see it connects to 10/10, but there is no long/lat.
What can cause all this mess? Is there some known bug with the gps? Or maybe some apps are interfering with others?
I also don't have any data plan (2g or 3g), so I only surf on wifi. Maybe this trows the location off somehow?

My location results are less accurate than 3g but still usable. Have you had better gps results from other devices? Your area might have some problems.
Cheers from my DHD.

When it works, it works just fine. Today on my way to work it succeeded in getting a fix after several minutes (which I still consider to be a bit too long - it should do it in less than a minute).
Last week, during a short jog outside of my house, it got a fix using RunKeeper.
Two days ago, while walking outside for well over an hour, and seeing in all the apps it finds multiple satellites, I could not get any fix at all. I want to use GPS only, no need for 3g or wifi. It should be enough (And had been enough on other occasions).
And it wasn't only defective two nights ago - many times I can't seem to get a fix. And only occasionally I get it to work properly.

I have the same problem ,i flashed a few different radios to try them and getting a gps lock was a nightmare.Originally i was on radio 26.03.02.26 and it was actually fine(shouldnt have messed with something that works.I have now flashed back to that radio and same problems.
i am sitting here with the misses hd and it instantly finds 6 sats and gets a gps lock while my hd finds one and does nothing.
i turn off gps on both phones ,turn back on and now her phone gets a lock at least 1 min faster.
Seems to be first time using gps after booting phone,once i have turned gps on give it a few mins then turn it off.I now run gps status on both phones,gps turns on and now get 2 more sats and a much lower error reading.

I have the same issues with gps, if I leave my phone flat on the dashboard of my car so that the screen is facing upwards, the gps seems to work without losing a fix, maybe because it connects to more satellites.
when I place the phone in my dash mount, it seems to drop signals and loses location.
I have tried a solution which I found while browsing the net extensively for the problem you mentioned and there does not seem to be much info on the issue. The solution I found on the net seemed to have made a huge difference although more testing is needed.
I have downloaded a program called "Tracker Booster - Tracker Booster is a small utility to help sports tracker applications (e.g. Endomondo) to get best possible GPS signal by keeping the GPS unit active in the background." It is available for free from the market, the way to use it is by starting this program up and then clicking "Start Booster" followed by "send to Background", then load GPS Status, hopefully once you see some satellites on GPS status and have a fix, you can now load your sat nav software or google maps, I use co-pilot.
Once you have finished with using the GPS, remember to stop Tracker Booster as it runs in the background and keeps your GPS on constantly which will no doubt drain the battery.
This so far has worked for me and as I have stated earlier, I need to do a few more trips before I can say that it works all the time.
I think this is the best solution until something better comes up.

This is not whats happening to me - When it's not working properly, I can't seem to get a fix at all, even after a long while. When I do get a fix, it works just fine even when the DHD is in my pocket, or facing sideways.

Has anyone one of you guys tried using gps status from android market?
Download it reset agps data than redownload agps data and that's it.
I get a fix in aprox 10s without it is few minutes

GPS is constantly "ON"

I have my GPS enabled. Half of the time I'm using my phone, everything is good, everything works fine. But during the other half of the times, the GPS is constantly on the notification bar. I try restarting my phone, still up there in the notification bar with a 'solid' gps icon which says "Location set by GPS"... I can even turn the GPS off, and then on again, and it still doesn't fix the issue. As i turn on my "Maps" app for the first time, my location is already "accurate to 3 meters" before it even loads the map graphics... How do i figure out which app is causing this, and how do i stop this? it's irritating. I have to constantly check my phone to make sure the GPS isn't active and draining my battery. And please, don't say "Just turn off the GPS". Android is designed to work with the GPS enabled. Even if the GPS is toggled "on", it shouldn't be using it unless it needs it, therefore using zero battery. (Just like wifi is supposed to). thanks.

I have the same issue and it seems like it's Maps that's constantly trying to turn on GPS. Once I have GPS off, my battery life is a lot better. Tried uninstall Maps, clear data, re-install...but the issue is still there but not all the time...very annoyed.

Another reason might be an app that is using gps in the background. Facebook, twitter, and other apps might be the problem?

If you have your google search settings on to make local search better, then the GPS will be on.
Facebook, Maps are all GPS hogs.
Just turn it off and on when you need it, the GPS on the S3 locks in seconds anyway, so its not a problem.

[Q] Wifi occasionally disconnecting in standby

So I've had this problem for awhile now with the wifi disconnecting itself during standby. The other day I decided to start fresh and went did a complete wipe and reflashed CM (10.1 RC).
The problem did not present itself during the 1st or 2nd day, however yesterday I noticed the wifi signal bar went grey for a second and reconnected. So I checked my radio version and noticed it was a few months behind, downloaded the latest and flashed it. Problem didn't show up until the next day where the wifi signal briefly turned grey and reconnected.
Wifi settings are set to always stay on when screen is off and I've tried almost every combo of settings in the wifi menu to stop it. This is fairly annoying since when I have wifi turned on I do not get texts since I use GV. Yes, I can turn off wifi and use my phone's internet, but I have bad signal here and the speeds are extremely slow.
I'm not sure what the problem could be, I always thought it was a bad flash the first time I did it and it was a bug. I thought wiping everything and flashing an RC would fix the problems.
Any thoughts on what could be causing it? I'm on stock CM with no custom kernels.

[Q] GPS issue after update to 4.2.2

I recently updated from CM 4.0.4 to CM 4.2.2 (10.1.3 to be exact), and I found that my gps is ALWAYS on, no matter what I do.
What I mean by is that, when I first boot the phone, gps is off, everything is good. Then I use an app that uses GPS - most likely Google Maps, which prompts me to turn on the GPS. I do that, GPS connects just fine, Google Maps locates me using GPS, everything is good.
The problem is when I turn OFF the GPS. I turn off the GPS via notification drawer GPS button, and GPS goes off, and I exit maps. The issue is then is shown in the battery history. Even when I turn off the GPS after using it, according to battery history it was never OFF, and from that point on it would keep showing GPS as on in the battery history.
What's funny is that even though it says GPS is on in the battery history, when I go to Locations Access it is clearly shown that Access to my location is OFF, and the gps box is greyed out as well. However, battery drain seems to suggest that GPS is actually eating away my battery, since my battery drain is significantly higher. Just to check if my GPS is actually on despite saying it is off in Location Access, I try using maps, and it is clear that GPS is not working in maps.
The only way to solve this funny situation is to reboot my phone, after which it would be shown that GPS is off in the battery history. However if I turn on GPS even once, the problem happens, all over again.
I have of course checked all my apps - the only apps that access GPS are Maps, Google Now, Facebook, and GO Weather, and I've made sure that location access in these apps are off. Well, with the Location Access in the system setting off in the first place, these shouldn't be working anyway.
I tried re-flashing 10.1.3, re-flashing gapps, and factory reset, to no avail. I suspect that kernel might be an issue, since I was using an old KT kernel before I updated, and it was slightly unstable. But if that is the case, I have no idea how to fix the kernel aside from re-flashing 10.1.3.
Can anyone help me solve this problem?

[Q] random reboot while using GPS for longer time

Can anyone confirm random phone reboots while using GPS for long time? I experience it regulary. After and hour and half or two hours of using GPS (either in car for navigation, charging/not charging) or on bike for tracking (screen off) with endomondo).
I'm going slightly mad because of this. I thought initially that the phone gets overheated with charger, but it reboots even with screen off, not charging). My other guess was the navigation application, but it happens also with sports trackers (endomondo, strava). So definitely it must be a problem of GPS driver or hardware. I tried various ROMs, CM10 or .211 or .96 ports, but it happens all the time.
Does anyone have more info or in the best case a solution for this? Thanks a lot!

I gave it some more thoughts. I use GPS Status with permanent notification with status details constantly being updated. I uninstalled it today, maybe this was the issue. Please, can anyone confirm that GPS Status is the cause of problems or that GPS Status is working fine even for few hours of gps activity? Thanks

same problem
Hi,
i have two xperia ion with the same problem. When i use GPS for tracking on my bicycle with locusmaps or oruxmaps it alway reboots after a while, it works maybe 30 minutes or one hour but then it reboots. The same with Navigon navigation, always reboot after about 30 minutes. Both smartphones the same problem. Running on Android 4.1.2, i downgraded the phone to ics 4.0.4 but the problem was still the same.
Did you solve that problem??
Thanks
Peter
