Google Navigation - Frequent Signal loss

Hey guys!
I'm having a issue with my GPS signal while using Google Navigation. The signal locks on in minutes and usually works up until 3min. After that it always looses it's GPS signal and tries to reconnect.
I don't really have a problem with losing signals... but the reconnecting part seems to go indefinitely.
Funny thing is, if i try to restart the application right away, gps locks on in seconds and resumes it's function until the next 3minutes.
I just can't seem to find a solution for this problem... Can anybody help?

Radio is not gonna help. Read the CM nightly thread. CM and Navigation currently have an issue holding a gps lock. No one knows why.

Oh, too bad
Thanks for the help though! I'll check out the CM7 nightly thread. Maybe somebody has a different navigation software working...

Any and all other navigation software besides "navigation" works. This problem is only on CM and only using google navigation I recommend copilot. Let's you download the the whole USA if you wish so if your in an area without service you still got gps. And they do update there maps frequently.

[Q] GPS wandering, any one found a software fix?

I've read just about every post in this forum that even mentions GPS trying to find a solution, but no luck, so I'm asking outright in case I missed something or someone has the answer and hasn't contributed it yet.
My One X has horrible GPS.
I'm not talking about how long it takes to find satellites, it does that quickly enough. What I'm talking about is using an app like My Tracks, Endomondo, Run Keeper, etc to record a track. If I sit the phone perfectly still and let one run, the position and track wander all over the map like a drunken sailor looking for a good time. If I actually move in a straight line, the position shows me blocks away from where I really am. If I try to use a navigation app, the directions are meaningless because the phone thinks I'm as much as 1/2 mile away from my actual position. (I should post a video of that, it's hilarious how bad the directions are.)
Please don't respond if the only problem you've had with GPS is that it took too long to find satellites and downloading someone's aGPS fix app or tweak solved your problem. I've tried all that, multiple times.
I suspect it's just bad hardware, maybe bad antenna connection or something similar, and I'm going to need to replace the phone, but before i go through the hassle of trying to get HTC to replace this dev unlocked phone, I want to make sure there's not a software fix possible. I'm past Expansys' 14 day return window, so HTC is my only option, or possibly my American Express warranty service.
Any thoughts?
The pic is a screen capture of the phone sitting in my parked car in an uncovered parking lot for about 10 minutes. Note how much it wanders around.

Well, no replies, so I guess that means a big NO to any one actually finding a software fix to this particular problem.
For what it's worth, I installed CM9 in the phone and the GPS is still unable to hold an accurate location, so I'm sure it's a hardware issue at this point.
That's a real pisser, since they told me the turn around time on fixing my phone will be 3-4 weeks at the HTC Warranty Repair center in Houston, TX.

I hate to say it, but it must be your unit.
I use GPS navigation very frequently (SoCal, USA) - and coming from a flawless GPS on SGSII, I have to say that HOX GPS is even better. It's more precise - it can even correctly show which side of the road I'm on. Also, driving past intersections is spot-on, which shows how on-the-spot it is.
Did you install any cases, or keep it somewhere where antenna signal may get blocked?

I didn't want to believe it, but I concur it's got to be a hardware issue. No case in it, nothing blocking the antenna. I have same issues even laying it on a patio table out in the open.
I'm also in SoCal...San Fernando valley and the west side of Los Angeles. The one time I tried to use the GPS for navigation it was like getting affections from the three stooges.

Mine does exactly the same. Calibrating the compass an turning wifi off while using gps solves it for me. Gsp is spot on whe wifi turned off... turn it on while navigating and it wonders off road....

I had the same problem, I downloaded GPS Test Plus from the Market, went into settings, selected Clear AGPS and then selected Update AGPS - seems to have been tons better since I did that.
Found this via an Internet search so Kudos to those who discovered it although I apologise I can't remember where I found it!

Yop this I remember even from the iPhone. Accuracy +50m when Wifi or Mobile network assisting with the position. Without max 5 . and not much wandering
Just turn it off in the location. As the breugiek above me suggested.

Thanks for the responses.
As stated in the original post, this is not an aGPS issue. I've tried many aGPS type fixes..Faster fix app, crypted fix and a few others.
I didn't mention it, but I've already tried turning of wifi; it makes no difference.
I suspect bad hardware, specifically something wrong with the antenna.
Annoys me no end to be HOX-less for a month. I've only owned the damn thing for 4 weeks.

Kinda meant the settings > location > Googles location service = un-check. But I guess you already tried that one :/ (but mentioning it just in case)

I'd posted a wandering track from a parked vehicle in the OP, but for those interested, here's a two-minute video of the HTC One X GPS in action while trying to use it for Navigation with the Google Navigation app.

Mine is the same but only when I stop the car at lights etc. Sat nav shows me going rallying across field and drowning in the sea when near the coast, sorts itself out when on the move again tho.

I may have found a fix (it works for me so far anyway) - see my post here...

Thanks for the suggestion, I've already seen your post in the other GPS is messed up thread. I tried it and it doesn't fix my phone. Clearly bad hardware.
Cheers!

GPS now working fairly well on this phone. It's not perfect, and requires WiFi off, but other than some initial wandering at startup I'm getting accurate tracks on it.
The fix was to install ARHD 7.0. No idea what changed from earlier versions but it works well enough to put up with until I can get a shorter repair time quote from the warranty center.

[Q] Compass off by 90 degrees

I've noticed on my new S3 that the compass is sometimes off by 90 degrees. Then, if I close the map app and open it later, the compass is accurate.
This this a known issue?
Thanks!

Not sure about this issue but I know there is a way to calibrate the phone somewhere in the settings. Not sure if it will help or is even related but might as well give it a try.

I didn't find a compass calibration, although I recall seeing a gyroscope calibration setting hidden somewhere (I'll have to find it again). Would that help at all?
I tried a compass calibration using the GPS Status app, but it didn't seem to help. It's strange. Tried it again on my way into work and it got some of the directions right, but wrong on others. It also seems to improve over time. I almost wondered if it didn't have a magnetic compass and was just using gps signals to guess at your direction. As far as I can tell, there is a real compass in there, although I suppose I can't be sure Samsung is actually using it.

Same problem here...
I'm having the same problem here on all my devices, so i'm thinking it is more likely a bug in android than a hardware issue.
Calibrating the compass with GPS Status (on the play store, can*t post a link yet) helps but never for long... quit google maps or navigation, and on next use I have to calibrate again.
I just verified this one someone else's S5, same there.

Another interesting detail:
I used to have the same issue on my Samsung S3, but with CM on it all is well now... so it really seems to be a software thing.

interesting: there's a two year old bug entry about this on google: https://code.google.com/p/android/issues/detail?id=37771
...it has been closed as "obsolete".
nice going there.

GPS locking issue unless coming from a reboot

I cant get a GPS lock with google maps unless I reboot my phone, I am on 4.1.2 official ROM ( non rooted ) GPS test shows an accuracy of 10-13feet with several sattelite locks, has anyone experienced the same problem?

Anyone? could this be a hardware defect?

I'm having the same thing. My GPS used to work perfectly until a couple weeks ago, and now I have to reboot otherwise it will not lock.
It says location set by GPS, but it isn't actually set, it's so weird, it's like it gives up looking. Anybody know how to fix this?

I've found this to be Google maps. Mapquest and waze can use the GPS just fine and lock on in seconds.

Slow/unreliable gps lock and wonky compass

Anyone else have issues getting gps lock? It will take me several minutes with a clear view of the sky sometimes. If I'm sitting in the back seat of a car I often have to press my phone right up to the window to get a good enough view of the sky and it will lose lock if I take it away from the window.
Also, the compass is all over the place and makes things like gaps walking directions almost useless.

Are youon kitkat? If so, Pls check the 4.4.2 update thread in the general forum where we have a new stock image with fixed gps and battery. See if it applies to your case.

I've noticed the wonky compass. It will vary wildly without any rotation of the phone and, in one orienration, will flip back and forth by 180 degrees very quickly. Thought about warrantying the device, but everything else (including GPS) is solid.
I'm on 4.3.

I have to calibrate the compass occasionally but it works fine for me. GPS normally licks in 10secs or so, but I keep GPS on all the time. It only uses power when you are using an app that uses it.

ive had a compass gps issue for a good while. thought it was the rom, then thought it could have been the case....but im thinking its just happening because i get same performance from jedi's 4.4 release....so not sure what the deal is but same issues....they gave me a gps fix that tends to kinda work.....but its not tracking fluidly and the compass just isnt staying calibrated for very long...its always looking in a different direction.....

Download and install topNTP from the play store give it root access click install at the bottom select create files and reboot.
I use this app after every rom I flash and it gives me a gps lock in literally a couple of seconds even indoors.

My Note 3 doesn't lock on to GPS inside my house at all. Outside, it seems okay, most of the time.
My old HTC Dinc2 locks on without any trouble, inside or out. Not sure if I should do an exchange, since everything else works just fine.
