[HTC One X] interrupt_me:
I'm on my 3rd handset from Vodafone UK, the last two have had the same GPS problem described in this thread.

Did this several times, did nothing to help the problem.

Did this too - after rebooting it got a lock incredibly quickly (in a few seconds), but again my speed, altitude and direction keep changing despite the fact I'm standing still.

Looks like I need to get yet another replacement, that'll be my 4th...
[HTC One X] AngelDeath:
distortedloop, yes I am getting the international version, I didnt want the att version because 1) its dual core and not quad core, 2) its 4g lte, which I dont use data, so the 3g is fine by me.
[HTC One X] breugiek:
This actually works! Position totally inreliable in Google maps, nor in CoPilot when WiFi is turned on. Once you turn off Wifi... accurate!

Nice and simple work around!! Tried everything else ... but this is nice :)
[HTC One X] distortedloop:
WiFi status (on/off) does not impact my issue. WiFi off, GPS on Locks in a few seconds, then records a meandering/wandering 1/2 mile walk in 2 minutes even though phone is 100% stationary.
[HTC One X] Try4Ce:
Had that issue once, dunno why that happened. But I do use navigation quite often (Google Maps / Navigon DACH).

Happened to me while in Google Maps, and that was during the day I bought the phone. I was thinking "WTF is happening there? I am effin standing still!" ... it resolved itself after some minutes, tho.

Ever since, I've used Google Maps quite often, and as well as Navigon DACH. No issues whatsoever. Just yesterday I used Google Maps Navigation to get a friend to a place nearby. Fast GPS fix, no weird behaviour, and WiFi was enabled.

Dunno, but IMO, its Software / Driver related. I use a rooted phone, running InsertCoin 6.3.0 ... The first day it happened I used the stock ROM tho. Probably it has been fixed already within custom ROMs... ?
[HTC One X] distortedloop:
How's the new phone?

Any GPS issues?
[HTC One X] AngelDeath:
Sorry DL, kinda been wrapped up.

As for the phone, its beautiful, as for the GPS, mine came with the rom 1.28.401.9 which the gps worked flawlessly, installed gps status it downloaded the agps and within 9 seconds locked onto 7 sats out of 16. Shut it down then re-did gps status, this time it was 4 seconds to 6 sats out of 16, as for mystery speed, I set mine on the table and my speed was at "0". Only once did the speed change from 0 to 1, then back to 0 after that for 3 mins it remained stable. I have since installed a custom stock rom of the most updated: 1.29.401.11 because the SDcard issue, and have not checked the GPS since, but will first thing tomorrow and post the results.

BTW I found this by accident, but did you guys know you can pull down the notification bar at the lock screen? And if you hit one of the notifications in the list or even settings, it unlocks the phone instead of having to use the ring, just a OTP FYI.
[HTC One X] knoxploration:
This seems to vary by app; some will get you through the lock screen when you click the notification. Others, it doesn't unlock the phone, but calls the app up, and when you then manually unlock the phone the app is waiting. Some, it doesn't call the app up at all, but it *does* still clear the notification, so you then need to manually launch the app, which is a bit tedious.
[HTC One X] :
This thread alone just made me cancel my HTC One X order on Amazon :(

As I am in the U.S I don't want to deal with warranties and repairs .
[HTC One X] distortedloop:
Your caution is probably warranted. I'm also in the US and I just got a repair ticket for my One X for its horrible GPS (can't hold a solid position fix) that I described earlier in this thread.

They said it will take 3-4 weeks to repair! Absolutely deplorable, and honestly, I have my doubts they'll actually fix the phone...they'll fire up the GPS and when they eventually get a lock, they'll say there's nothing wrong with it.

Too many problems (not just GPS) for too many people, and obviously the repair centers are overwhelmed.	The guy helping me said that most people, when told it would take so long to get the phone back, decided just to live with the defect they had. Incredible.

I was lucky with mine in terms of no screen or flex issues, but the GPS is just plain broken.
[HTC One X] knoxploration:
Record a video of it side by side with a known good device, showing the length of time taken to achieve a lock and number of satellites seen by both. Post the video on YouTube, drop an email to HTC support with the link. If you genuinely have a problem (and one that's publicly visible and hence likely turning folks away from their product), I don't doubt they'll act to get it sorted...
[HTC One X] Bright.Light:
Exactly my problem.

I walked a route of 10,5km (Google maps), but the device had measured a route of over 14km! Here's the plot: http://www.mapmyrun.com/routes/view/97441439

Edit: I did not have this problem while cycling, so speed might be the real issue. Maybe all speeds below 5km/h (or slightly higher) result in inaccuracy. Maybe because other measuring tools are used then?
[HTC One X] hetalmp:
I had to go through two phone replacements just because of GPS and now my phone is perfect with GPS. All previous problems around gps have been fixed with it wandering etc. Strange thing was I went from a serial number HT23 to HT24 back to HT23 where it was fixed.

Before my final replacement I had tried all the HTC recommendations like clearing locations, factory reset etc and none helped. Only replacing it sorted it out.
[HTC One X] distortedloop:
Not side by side, which is a great idea, but I did record the GPS in action. 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.

http://youtu.be/_nxptMIPuIE

Side by side with my Samsung phone would be even more powerful, but I think this video speaks for itself.
[HTC One X] gothier:
Same problem here. I get a fast fix but the location starts to jump just at the same time - GMaps and Navigon DACH.

Tried WiFi off und reset AGPS Data. No Luck. Running Revolution HD 6.0.0. Looks like the GPS speed is never at 0, starts at 30 and gets up to over 50 km/h, having 8 sats und standing at open terrain.

Oliver
[HTC One X] ricksonchow:
Yes I got some similar problem with the One X. I made a side by side comparison with my old but reliable Desire, During high speed the One X is find. But once slow down, the one x like to overshoots and begins to turn 180 and start rerouting on the maps were the desire shows the accurate loctation. May take back to HTC later to sort it out.:(
[HTC One X] Vitucastro:
I have this issue on my HOX too, although when I set to airplane mode gps status shows me working properly...

---------- Post added at 10:19 PM ---------- Previous post was at 09:38 PM ----------

Could you guys test the GPS while in airplane mode (no data assist) a good app is gps status!
[HTC One X] NineToTheSky:
Makes no difference to me. Still not locking on to any satellites.
[HTC One X] distortedloop:
Airplane mode makes no difference on mine.

In what way does GPS Status show you working properly? You've got some satellite locks? Look at the actual position location information, are the last three numbers stable or constantly revising your position? A couple of points move might be acceptable, but if you have a "really messed up!" GPS then those numbers will be changing by quite a bit. The best way to test for the major issue many of us are having is to use an app like My Tracks or Run Keeper, then sit the phone down and let it record a track. If your unit is bad, the track will show you wandering all over the place, if it's good, it won't move or will only move a meter or two. Let it run for a few minutes to be sure. Another sign is you can't see any satellites while inside. My first HOX I had to go outside to get any sats.

I just picked up a second HOX and sat it side by side with the first. Night and day difference. On new one, GPS locked, inside the house, within 12 seconds. The My Tracks test the track never moved. Perfect.

You have a defective unit. I suspect it's an antenna issue, but that's just wild ass guessing, but makes sense given the symptoms. Save yourself the grief and exchange your phone if you still have that option.
[HTC One X] Vitucastro:
Well i guess mine is fully messed up. Not sure why now i get same crazy moving around results again even on airplane mode!
[HTC One X] NineToTheSky:
Sadly I don't have that option. I have spoken to HTC, and it will be going back for repair.
[HTC One X] knoxploration:
How much "crazy moving around" do you get, out of curiosity? Just tried installing My Tracks and left the phone sitting on the windowsill running for ten minutes. Unsmoothed, I got 0.13 miles (686 feet) of motion in 616 seconds, or an average drift of just 1.1 feet per second. All of that motion was constrained in an area of about 150 feet, interestingly almost all of it in a close to perfectly straight line. (Perhaps my house shielding half the satellites, so the phone couldn't quite locate itself in one axis, I'm guessing.) Most of the time it actually stayed inside an area of ~50 feet, but it did jump ~100 feet mid-way through the ten minute period, with a peak speed of ~6mph. Perhaps that was as a new satellite became visible, or one became obscured, causing a different fix.

My point: it seems quite accurate to me. Most of the time even indoors with visibility of less than half the sky, it mostly stays within a 50 foot radius and drifts less than a foot per second on average. It's not perfect, but I don't think my dedicated TomTom GPS would do any better with smoothing and snap-to-road disabled.

So I'm curious how much drift you folks are seeing.
[HTC One X] Vitucastro:
So mine is totally crazy, it moves all around in a 1000ft radius or more and keep spinning like a drunk guy, pretty much like in this video http://www.youtube.com/watch?v=NkzOfAtvKbY
[HTC One X] knoxploration:
That video doesn't really tell you a lot unless you sit and transcribe the GPS coordinates, which I can't be bothered to do. It will always look like a crazy drunk guy unsmoothed, because even small motions around a set point when you're sitting still will lead to the impression of direction change if you're not using the magnetic compass. Likewise, jumping around in a relatively small area can give inaccurate readings suggesting significant speed, without damping. (I left my phone running for 45 minutes and in that time hit a peak of 9 mph, nowhere near that in the video, but I don't know what conditions it was shot under.)

With a track logger and the phone given a view of at least somewhere near half the sky, how far is the furthest you record having strayed from your real location while leaving the phone sitting still, and how far does your phone believe it has travelled in a period of, say, ten minutes? Are you talking hundreds of feet, thousands of feet, miles, ...?

Edit: Whoops, you mentioned the radius, missed that. Is that indoors or outdoors? How much of the sky visible unobstructed to near the horizon? How many satellites locked?
[HTC One X] Vitucastro:
Does this video gives you a better view of what is happening with some ONE X? http://www.youtube.com/watch?v=hcbtRUHBo40

I'm pretty sure this is not right!

And yes, outdoors, keep locking and unlocking with some satellites.
[HTC One X] knoxploration:
Recorded indoors according to the submitter. That's probably half his problem right there. Even dedicated GPSes often have a difficult time getting any reception indoors. If it's intermittently, partially seeing several different satellites, that can lead to the GPS receiver suddenly changing its mind about its location, giving a perception of motion on a stationary GPS.

Even some types of coated car windshield glass can be enough to block GPS signals:

http://www.gpsmagazine.com/2008/09/garmin_confirms_coated_windshi.php

Locking and unlocking is not in itself unusual. It could be there are obstructions, especially if they're low to the horizon, solar activity (eg. http://www.gps.gov/news/2012/03/solarstorm/), etc.

The question is, is it losing lock on satellites that are high in the sky and unobstructed? If so, you probably have hardware issues.
[HTC One X] wintermute000:
I got no issues getting a fix but if driving and I stop at the lights it sometimes starts spinning around.

Not a deal breaker as as soon as you start moving again it sorts itself out but definitely annoying.

I just flashed ARHD over stock 1.29.xxx.11 and haven't used the nav yet so going to see if that helped
[HTC One X] Vitucastro:
Check out this video at 2:10 http://www.youtube.com/watch?v=fXcEQ3-jdd4 no compass changes and as soon as it gets proper locking you get no changes ins coordinates or speed, that is how it should work, I'm sending this one back as DOA and lets see how the new one performs !
[HTC One X] wintermute000:
ARHD appears to have fixed it
[HTC One X] distortedloop:
There are certainly varying levels of issues with GPS with many possible causes, but some people are too quick to dismiss other people's problems. Some HOXs clearly have defective GPS functionality...probably bad antennas.

I'm able to compare GPS across several devices because I've currently got the following functioning phones: two HOXs, a Galaxy Nexus, Droid Charge, Thunderbolt, Galaxy S 2, Nexus One. So I've got plenty of opportunity to compare.

I've ruled out "being indoors", "auto glass coating", "cloudy weather", "smoothing", etc just by pulling out a second device and comparing it to the defective HOX. Indoors, both at my office and work, the HOX can't get a satellite lock, every other device I have, sitting right by the HOX, locks up in seconds. Same in the car.

Check out this little test walk I went on while waiting for my friend to get his passport the other day. I had a bad HOX and a Galaxy Nexus with me:

Nexus results: 0.81 miles at 3.1 mph with 200' elevation change. Largest variation from actual track ~10'

HOX results: 6.80 mile at 81mph with a 2100' elevation change. Largest variation from actual track ~1600'

This kind of variance makes using the HOX useless for just about anything other than getting a general idea of what part of town you're in. You can't use it to record your runs/hikes/cycling activity, and you can't use it to get reliable Navigation app directions. Check out my short video demonstration of trying to use Google Navigation with the bad HOX. You can't defend that kind of performance...

Now to be fair to the HOX, my second one, just acquired, has spot on GPS function. It locks up fast, even indoors, and holds position within a few feet of actual position. Not all HOXs are bad, but there are plenty of bad ones out there that should be returned for repair if you ever hope to have decent GPS function. Problem with that path is the turnaround on repairs is a month according to HTC when I got the RMA approval on my first HOX.
[HTC One X] Vitucastro:
Well said!

Now we see some issues with the wi-fi antenna connectors, seems like HTC really screwed up with the HOX!
[HTC One X] distortedloop:
Thanks, and agreed about HTC really screwing up this time. The WiFi antenna issue solidifies in my kind that the GPS issue is likely the same. The WiFi problem threads are similar reads to the GPS ones. People's complaints dismissed with "your router is bad", "you're holding it wrong", and the like.

I've disassembled a couple of iPhones to replace screens, and even did a headphone module transplant on my Galaxy S, but I'm not sure I want to take apart my bad HOX to try to diagnose and fix a loose antenna connection. Will probably send it in for warranty work, even though HTC says a month turnaround.

---------- Post added at 10:28 AM ---------- Previous post was at 10:00 AM ----------

A little google search revealed this thread. Apparently HTC has a bit of history with bad GPS and it was indeed antenna/antenna connection related. No way I'll be soldering any wires in mine, though! LOL
[HTC One X] Vitucastro:
Hey let me know if you figure it out where and if there's same issue with GPS antenna!
[HTC One X] Freakaz:
Tried using GPS while tracking running progress with Runkeeper for a couple of runs. the first time GPS was jumping around like 20-40 meters from my actual place. Then the second time i tried it with disabled Google's location service, mt position was inacurate for like 5 mins, and then it became completely normal and tracked my route with great acuracy. I'll try it in an airplane mode on my way home today. I still hope it's not a faulty hardware issue.
[HTC One X] Vitucastro:
Anyone figured out if the GPS antennas is in the body shell? Maybe we can fix as people are fixing the wi-fi signal issue!
[HTC One X] Bright.Light:
And anyone tried to press the device on that spot just to see if GPS reception gets better? (I don't know what spot to press, so can't test it myself)
[HTC One X] Vitucastro:
I don't have my HOX with me, probably will get a replacement or switch back to Xperia S or even try the S3
[HTC One X] Freakaz:
Took my old bluetooth GPS receiver, that was long time forgoten, from a drawer today, paired it with my phone and it worked perfect. the tracking acuracy is way better than it was on my old desire, not to talk about the faulty HOX. So, looks like i'll have to cary one more gadget, when i need a GPS.
[HTC One X] manikm303:
haha i was thinking of doing that - but cant find it! used to work well with my Windows Mobile 6.1 device and TOM TOM

WHAT IS GOING ON!!!

when i use the latest firmware, i get NO LOCK!

when i use older firmwares i get locks ok, but the JUMPING around makes it useless.

problem is, ive rooted....do i send the phone back to Vodafone (bought from Phone4U but with a voda contract just 4 weeks ago) or send it to HTC

even more annoying is, when i bought the phone before software updates and knowing any of these problems, IM SURE i had GPS inside my little house, no even next to window no LOCK!

but my NEXUS ONE (god bless it) gets a lock fine!

GRRRR!

send the bugger back/ or wait for a NEWER software....? that is the question
[HTC One X] knoxploration:
My money's on a hardware problem (poor antenna connection or similar) that's progressively gotten worse, coincidentally around the time of the firmware update.

If it was a software problem, it wouldn't work fine for most of us.
[HTC One X] ChefChaudart:
me too

Hello,

I must join your club :(

I tried ;

- Switch off WiFi ; does not help

- Delete Agps date ; does not help

- Switch to plane mode -> THE SOLUTION :D

then the navigation is pretty precise ...

At least, it is not a hardware problem :cool:

Maybe it is done for safety when driving :rolleyes:
[HTC One X] victorio404:
It happens to me only when indoor(marker jumping and moving around the real position) - when outside the positioning is perfect.
[HTC One X] knoxploration:
Ditto. Just tested outdoor earlier on, and it was actually capable of registering me walking just five or six normal paces.
[HTC One X] HyBry:
Not sure what to make of mine.

indoors the reception seems terrible, but I'm no too bothered about that.

Took the phone on couple of runs and although it was not perfect it was decent for when it worked. The problem was that both times it stopped tracking me half way through. Funny thing was that it showed that I had GPS signal and the location I was at, but it was just not logging that information.

Did another check this morning on my way to work and it seemed fine at first and then it suddenly crossed the road (according to an arrow on google maps) and started spinning around.
[HTC One X] nearlygod:
I got the same problems.

Has anybody send their HOX to HTC?

Did you get it repaired or replaced? Is everything fixed now?

cheers, nearly
[HTC One X] ChefChaudart:
it is not hardware related ...
[HTC One X] NineToTheSky:
I sent it off yesterday. I'll let you know when I get it back.

---------- Post added at 02:44 PM ---------- Previous post was at 02:41 PM ----------

Oh yes it is...

There are two problems: one where it can't lock in accurately, which is probably software, and the other where you can't lock in at all, which HTC have confirmed is hardware.
[HTC One X] nearlygod:
how do you know that? In this thread are peolple with 2 hox. one good the other bad...
[HTC One X] ChefChaudart:
I´m pretty sure it is not hardware cause, as I said a little bit before, in Plane mode IT WORKS !

( And I had a similar situation with my Xperia )

[EDIT] Finally I´m not sure Plane mode is the solution, cause on my way home, even in plane mod, localisation was erratic ...

[EDIT2] I forget to switch off Google localisation service, when off, it seems better, I mean perfect (?).
[HTC One X] Freakaz:
Well i used external gps receiver via bluetooth an it worked perfect yesterday. But today gps was crazy and jumpy again, the only diference was that i was connected to the internet via mobile data today. So i think it's both, the hardware and software that is f***ed up. Good thing that it works better (is usable) in plane mode and with disabled google location services.
[HTC One X] hetalmp:
The only fix I found for this was a replacement. Had to go through two. My guess would be perhaps some interference from another component with it not being shielded adequately. But that is a guess. My current hox is perfect and I am able to enjoy the phone. I advice to go for a replacement while you can.
[HTC One X] theROMinator:
Hi,

I'm purchasing a One X soon, although. I have heard of this issue and more, have they been addressed by HTC? I will be purchasing the white version from Expansys US. Has anyone bought there's from them? Please share your experience(s).

Thank you,

theROMinator
[HTC One X] knoxploration:
As usual, nobody can tell you anything meaningful. All we know is that some folks have problems, and they're likely in a minority (or there would be much more complaining going on.)

As for Expansys, I bought both my phone and car dock from them, and the experience was superb.
[HTC One X] runwaypimp:
My GPS is useless too. It take five minutes to lock-in & then the position jumps around(using runkeeper)

HTC have some serious work to do patching this.
[HTC One X] distortedloop:
You are WRONG. It is clearly an antenna issue...just like the issue many are having with their wifi/bt antennas.

I'm one of them. I have TWO HOXs in my hands right this moment. One works perfectly. Does everything I expect it to do no matter how the rest of the radios and services are configured. The defective unit has jumpy GPS (records a .8 miles walk as 6.8 miles on My Tracks); and it does this regardless of airplane mode, localization mode, agps refresh, etc.

You're still wrong. NO IT DOESN'T (at least not for those who have the hardware issue).

And seriously, get real...what good is GPS without a data connection? No map information in most apps, no traffic information in those with maps, no points of interest information, etc, etc.

You're really missing the whole point...the GPS is supposed to work, and work properly at that, whether you're in airplane mode or not. if yours doesn't work unless it's in airplane mode, it's broken, messed up, malfunctioning. PERIOD.

It's broke, get over it. It's supposed to work PERFECTLY even with Google localization on. I think you're in denial and just don't want to admit that there is something wrong with your GPS.

There are different levels of broken phones it seems; why not just acknowledge that some (quite a few I think) have legitimate issues?
[HTC One X] ChefChaudart:
I´m not convinced.

If it would be a GPS hardware failure, why in some conditions ( software related ) it is working perfectly ?

A hardware failure is a failure in every cases, not in

some

cases.

And as far as I remember, my very first tries early april, without my holder, positioning was excellent.

Meanwhile, there has been some program updates ...

I´ve driven many years without data connection, I can continue. And as it is forbidden to use its phone (to call) in cars :p
