Mine got sent back to HTC has a hardware fault for repair.

I took screenshots of 'My Tracks' showing the tracking with airplane mode on and off to show the difference. Printed it out, which a clear description of the problem and included it with my 'tick sheet' when I sent the phone back.

Just checked the online tracking and it is marked as 'repair completed' today and has now been passed to UPS to deliver back to me.

So

hopefully

the phone will work as it should when it comes back - but I'm not holding my breath..

I'll let you know.

It'll probably be Monday now before it come back - stupid weekend. I'll just stare out of the window at the rain.

Hi all!

I just now noticed that my GPS is way messed up aswell....

Downloaded MyTracks to route my walk and it was just zigzagging ALL over the place. Was no straigt line to be seen anyware....

*Sigh*. I was SO happy with my phone, thought it was flawless....

Well well....

No WiFi on just 3gp.....
[HTC One X] stuart0001:
Sorry to hear that. I fear that the problem is widespread its just that most haven't discovered it yet.
[HTC One X] Aja82:
Yea I had my phone for quite a while now but today was the first time I actually wanted to use a tracking feature....

Totally useless in it's current state though....

Well I'm going to start reading this thread and see what I will decide to do.
[HTC One X] dezborders:
OMG.... It's so quiet on xda. My GPS is running perfect (with workaround), my Maximus 2.05 Rom is fast n stable and there's no new Base likely for several weeks. Will need to get a life outside of xda

@distortedloop

As u requested, I flashed ARHD 7.1 after running superwipe, and gps was usual screwy locations and unusable with default gps.conf file - both with WiFi on and off.

Incidentally I then set UK ntp server using fasterfix app and noticed the app completely overwrote GPS.conf file with a smaller GPS.conf - 4 or 5 lines were missing from fasterfix version - do NOT use fasterfix on a hox with the GPS issue, instead edit 1st line by hand in text editor if you want to select a localised ntp server and still want to keep the no agps settings.

Next I copied in non agps conf file and rebooted. GPS worked reasonably ok for sat nav whilst moving but jumps around when stationary (with wi fi off)

Finally I Did my own final step to fix GPS - Nandroid backup / superwipe / restore Nandroid, and now GPS is stable both whilst moving and stationary (and with wi fi disabled)

Not entirely unexpected as ARHD and Maximus are both the same Rom base.
[HTC One X] danlat1415:
Received mine back from HTC repaired.

My test so far indicate it's been fully repaired and is working perfectly.

I haven't had chance to go for a drive to test it fully, but 20 minutes stationary in 'My Tracks' has given accurate results.

no more bouncing all over the place.

I highly recommend to anyone with this issue - to highlight it to HTC and return your phone for repair.

My phone was rooted, so I relocked the bootloaded and reflashed a RUU before sending it back.

When sending anything off for repair, they provide you with a tick sheet - which the service department see when it's sent back. The description of the fault is summaried to just a few words - so to avoid the risk of them just reloaded the software of not fully understanding the problem - I added an extra page, where I included 2 screenshots of 'My Tracks'. one with airplane mode on, and one with airplane mode off - to highlight the signifiant difference in accuracy.

I tried to get the point across that it doesn't seem to be a GPS antenna issue - as the accuracy was great on mine in airplane mode.

The issue seemed to be interference from the WiFi/Data antenna dependant on which signal it was trying to use.

HTC seemed to have got the message and fixed mine.

I'll let you know once I've been able to run more tests. Hopefully I've got a perfect phone now.
[HTC One X] dezborders:
So you got your original phone (same imei) returned fully repaired and not a replacement ?
[HTC One X] danlat1415:
Yes, original phone repaired. The bootloader was also still set to relocked.

I was hoping for a replacement - a new 26 model so there is less chance of any other issues coming up, but I'm not complaining.

My 24 model has now been repaired as it should.
[HTC One X] dezborders:
Cool so how long were you without your hox? And are u in UK or elsewhere :)
[HTC One X] danlat1415:
I'm in UK.

Phone got collected by UPS, arranged free by HTC last Monday and I received it back by UPS free of charge yesterday.

So took 7 days.
[HTC One X] dezborders:
OK thanks. I have taken the plunge and arranged repair. UPS pick it up tomorrow afternoon at my place of work. Tonight I re-locked and flashed RUU back to branded H3G software. I also added screen grabs and details on seperate sheet regarding the issues. Fingers crossed I get it back quickly, and fully working ;)
[HTC One X] danlat1415:
Sent you a PM to help with what to put in your fault description - similar to what I put.

hope it helps.
[HTC One X] danlat1415:
Another tip when returning your phone.

HTC recommend using your original box to pack it in. Don't - because you won't get it back.

They return it in a new smaller box shaped like a present saying - I'm back...

This is a nice touch, but not if you lose your box and want to sell your phone in future.
[HTC One X] ChefChaudart:
HTC is not quick

Lucky you ;)

Mine was asked for return june 15th, finally picked up 22th :o but today is still marked "Waiting for device" on HTC site :mad:

Aaaaaaargh too late ...
[HTC One X] delfo3:
true reality
[HTC One X] danlat1415:
I found out the hard way. Lost mine now - just tried to warn others.
[HTC One X] twe69:
I was told not to include the original packaging by the HTC rep.... Guess you got someone who didn't know.

Did you do it through the online chat? If you did then there is a record which means you should be able to claim for a replacement one as it is their fault.
[HTC One X] dezborders:
I didn't use the original box, I had a large sheet of bubble wrap lying around and a jiffy bag. :)

Included an a4 sheet describing problem plus screen grabs from my tracks

What I forgot to include was a copy of my purchase invoice for the HOX, so now I guess this omission will cause a delay in processing the repair.... My own fault :/
[HTC One X] danlat1415:
You don't need a purchase receipt for the hox. They ask for this as standard to verify your warranty period but as it was only release a couple of months ago you'll be fine. I didn't include mine and didn't have a problem.

Yes mine is still running fine. I've had sat nav on all the time now in my car even on small trips just to test it, and its still running perfect.

I've re-rooted it to and tried various roms (currently on arhd 7.1) and it hasn't affected it at all - co.firming our suspicions that it must have been a hardware fault.
[HTC One X] dezborders:
I emailed HTC support a scan of my receipt this morning., just in case.

Great news your re rooted hox still works fine. Did you have to resubmit your unlock request on htcdev?

My network (3 UK) are still on 1.28 base so I may need to re root as well once I have tested the repair is good
[HTC One X] rfgamaral:
This thread is becoming a little bit a long and I'm getting really confused so I apologize if this has been mentioned/answered before.

I've been running some tests with My Tracks and here's what I've noticed:

GPS & WiFi On: It fluctuates a little bit while standing still.

GPS Only: It didn't quite stood still but it didn't fluctuate like it did with WiFi On. It was much better.

I didn't perform both these tests with an open sky, the phone was still on my window in the 1st floor of a building. I'm going go try and do a proper with an open sky tomorrow.

Now, I've also tried before to use GPS navigation (NDrive) and it seemed ok, nothing like what people mentioned always calculating alternative routes. But I'm not sure I had lots of WiFi hotspots around that area so I guess only the GPS was being used. Maybe we can't draw any conclusions from this? On a highway, for instance, it was perfect, the recorded line followed the road nicely, it didn't fluctuated at all.

What do you guys think of this?

Tomorrow I'm going to try and cross my university campus both with WiFi On and Off, it's full of WiFi hotspots and record both tracks and post them back for you guys to take a look.

And just to be clear, the problem most people seem to have is with WiFi On or Off? In other words, does anyone here have (or had) a messed up GPS while only using the GPS and everything else turned off?
[HTC One X] dezborders:
It appears that different hox have different severity of hardware fault and yours seems less so than for many of hox owners in this thread.

I have experienced sudden and sizeable sat nav errors in location, direction and speed of travel - even in the middle of the countryside with no wi fi devices anywhere nearby.

For me simply having wi fi turned on (but not connected or in range of a router or hot spot) is enough to totally screw my gps signal.

Let us know results of your tests as its all useful information :)
[HTC One X] danlat1415:
I didn't have to resubmit to request a new unlock code because it's based on your phones IMEI, so it stays the same - you can use the one that you get emailed from your first request.

Not sure, but they may update the software on your phone - because the first they do with all phones is wipe them and re-load.

(I'm not sure whether they reload you branded software, or unbranded - you'll have to wait and see).

Still no problems with mine since HTC repair.

I seem to have been lucky - I've heard stories on forum that they've had to send back 2 or 3 times. I made sure I made the issue perfectly clear when I sent it off to avoid any confusion.

I've been using different SatNav programs all week, and all work perfect:

Sygic Navigation, Navigon UK, CoPilot Uk and Google Navigation & Maps.

Hope yours gets fixed.

Good luck to anyone else with this issue.

Don't settle for trying to get round it with software and turning off settings. Your phone is worth nearly £500 so you deserve it to work as it should. HTC collect it, repair it and return it all for free, even rooted phones.
[HTC One X] dezborders:
The online tracking status today shows as "in repair" - hopefully my hox did not get a Friday afternoon "run flash and ship back to customer" lol
[HTC One X] rfgamaral:
Please take a look at the attached image...

I took both my phones and recorded at the same time a short walk around my house. All tracks are labeled in the image and blue one is the real path of my walk, more or less of course, it was drawn manually. It's just to represent that I walked mostly in straight lines...

This seems normal to me... What are your thoughts?

First I thought I had this GPS problem because inside my house the GPS was all jumpy and I believe that's also normal because the GPS can't properly lock on the satellites. But I always had my Hero alongside me and that didn't happen with it, that's why I found it strange. But, after the test you see attached, both tracks seem almost the same.

Today I also used the GPS for a longer trip, driving using Google Navigation and I didn't notice any major problems, it followed the roads correctly, it never recalculated the route (unless I explicitly went for another route myself). Sometimes I noticed that the locked-on location was not exactly where I was at (a couple meters off) but I believe that the GPS on our phones can't do better than that, their not military lol. Also, the Google satellite images are probably not that accurate either.
[HTC One X] dezborders:
It looks pretty ok to me .... Apart from the street with (tall?) Buildings on either side, which is possibly slightly disappointing. Your description of car navigation also sounds like a working GPS system ;)

So what - if anything - worries you ?
[HTC One X] danlat1415:
I agree - it seems pretty normal to me.

If you had a significant problem, then the signal would jump streets away from your actual location and constantly change into all directions (looking like a scribble on the screen).

An easy test is to run a car sat nav program, but stay stationary. If the positioning is constantly turning round thinking you're facing different directions, or jumping onto the next few streets - even though you haven't actually moved - then you've got a problem.

From what you've drawn on the map - it seems pretty normal.

Tracking a walking route is always going to be slighly wobbly due to the accurancy not being perfect.

Car Sat Navs are able to seem more accurate than they are, because the signal positions on a specific street - rather than trying to show an exact location on the position of the road or on the path.
[HTC One X] ChefChaudart:
Mine is on this status since 27th ...:crying:
[HTC One X] rfgamaral:
I only wish the precision was slightly better between tall buildings and even on open space could be slightly better. But since my Hero reports the same inconsistencies, I guess it's normal and will have to deal with it.

Thanks guys for the feedback and sorry to post there when I actually have a working GPS. I meant no disrespect, I just want to make sure I have a fully working device while still in the return period... Thanks again.
[HTC One X] danlat1415:
No problem - all posts welcome. if you're not happy with the accurancy, you did right to post and ask for feedback.

HTC offer 2 years warranty, so you'd have more luck repairing your device that way if anything was wrong, rather than return to supplier for replacement, as replacement could have same or different issues. At least if yours is repaired, you know it's sorted.
[HTC One X] dezborders:
Well I got my old HTC DHD to keep me going so better HTC take time and fix gps right rather than quick turnaround ;)
[HTC One X] dezborders:
Not at all m8 its useful for everyone reading this thread to see example of working and faulty hox gps
[HTC One X] Minitronic:
Good thread here, just thought I'd let you know my experience. I had the fault as described pretty much throughout the thread, a mytracks 10 minutes track had me moving all over the place into fields/streets etc even though the phone was stationary. That test was with pure gps on, no wifi. Other examples were using running/walking apps where it was close-ish to accurate but the line was zig zagging all of the time, once again not accurate enough. Lastly driving navigation was terrible, it had re-routes all through a 1 hour journey. The speed test apps on the market would also have me moving at over 60mph :eek:

My main issue was that I work in a phone shop so I could then test 5 other devices admittedly not over such a long period and all 5 devices showed the same fault. The stock ranged from different serial codes so sadly I exchanged it entirely for another model. From the sounds of it HTC are doing a better job of repairing these handsets directly, so my advice would be to send it direct to them with the mytracks printout and an exact description of the fault. Shame as otherwise its a cracking phone!
[HTC One X] stu_tls:
mines stuffed too so I shall be visiting my three store tomorrow maybe I can get a replacement here in the uk under the 28 day satisfaction crap! doubt it though

[HTC One X] stu_tls:
So I have just taken this device back to three store and they swapped it with no questions really

The only thing is the new device doesn't get the 28 day satisfaction it runs from the first purchase date and I'm on day 27 today!

But looking at the GPS its looking to be the same and not tracking correctly!

So I now have to decide if I go back and exchange this one or just send it off for repair! I did try checking in store but the GPS would not pick up a location inside.
[HTC One X] stuart0001:
Touch wood, but I think I've finally got a perfect phone.

The GPS tracking is absolutely rock steady and accurate.

Even with the other phone I had with good GPS (returned for other reasons) I would find that, when stationary at a junction, the compass was a little iffy as it would show me in the right place but facing the wrong way, causing navigation to reroute but then correct itself as soon as I moved, ie fine when using GPS and direction of travel but screwy when relying on compass.

With this one I don't get the issue at all.

So it looks like as well as GPS issues there may be compass issues at as well. Something to try to recalibrate the compass is to wave the phone in front of you in a figure of 8 a few times. It definitely helps.

Either way, as others have said, there are good devices out there so if you have a fault, don't put up with it. Get it exchanged or repaired.

Also, previously my phone would get really hot when running Google Navigation but with this one it seems to be much cooler. Perhaps the iffy chips/interference caused this too

PS. Any chance of changing the title to "GPS really messed up" as there's no such thing as a GPS compass in this phone, they are 2 separate elements and this discussion is about GPS issues. I think people looking at the title may think it's about compass issues due to the current title.
[HTC One X] ChefChaudart:
A return from HTC, my device being sent weeks ago ;

"We continue to work on it, there is a lot of pieces to change" :D:crying:
[HTC One X] stu_tls:
So I took my second phone back and was refused an exchange!

currently going through complaints with 3uk

they wanted me to send it in for repair and if they couldnt repair it they would send a new handset which is fair enough but its a new phone and i want it swapped and because im paying for it i want to bloody use it

watch this space :mad:

Some useful info here that may help (from the WiFi antenna fault thread)

http://xdaforums.com/showpost.php?p=28221580&postcount=1774
[HTC One X] danlat1415:
May be that they're waiting for parts.

I heard HTC were securing the WiFi antenna on all returned devices regardless of whether they had that issue or not.. since they found the manufacturing fault. So possible short of parts in Germany.

You could try and be cheeky and ask for compensation? A free case or speaker or something. Weeks without a device only a month old due to manufacturing issues isn't right.
[HTC One X] stu_tls:
excellent thanks for that i was just about to start searching online for this sort of thing
[HTC One X] danlat1415:
In the UK, the Sale of Goods Act says that the 'cooling off/satisfaction period' starts on the date the goods are received and not the date of purchase.

This covers you against back orders. You could purchase something but not receive it until 3 weeks later, doesn't mean you only have 1 week return time left.

If a product is replaced, the warranty starts again on the date the item was replaced (not including extended warranties). This covers you against receiving a 'dead on arrival' replacement and not being able to return because of claims its after the warranty period. The replacement should be a brand new item, so is covered under the 28 day return policy.

Argos get exploited with this all the time. People can buy something and return it within 28 days and replace it; then keep doing that 26-27 days and you'll always have a brand new item.
[HTC One X] stu_tls:
didn't know that thanks

looks like I'm getting well educated in sales of goods act

thanks all
[HTC One X] sleet77:
Ok, i HTC sent my phone back yesterday after 2 weeks and...

they said that everything is working fine... Un-****ing-belivable...

So I packed it and sent again with explanaition what exactly is broken ( A4 sheet, plus printed tracking maps). Hope this time they will do it right.

Im pissed, seriously.
[HTC One X] danlat1415:
I knew HTC were doing this - which is why I recommended sending a separate sheet fully explaining what's wrong.

Because the service department get a very summarised description of the fault, they're likely to get told GPS is faulty, so when they run the specific GPS test that checks only the GPS antenna, it will show to work perfectly.

Our issue is interference from WiFi/data antenna so they need to test GPS when running both.

Hope yours finally gets sorted this time.
[HTC One X] dezborders:
Mine since 28th... No change yet

More problems with the HOX! Driving into London nearly threw the piece of crap out the window. Then it might have been closer to the side road and going the wrong direction as it was saying. Sat still in traffic needing directions and it just started having a fit saying I'm 3 roads away and rerouting me every 5 seconds. This is an absolute joke of a phone. Appalling.

Only solution is to send for repair?
[HTC One X] danlat1415:
Yes send it for repair.

Don't use the original box, you won't get it back.

When you send it off, include a separate a4 page with your own description of the problem and screenshots of My Tracks showing your GPS going all over the place.

PM me if you need a hand.
[HTC One X] runwaypimp:
I got my GPS faulty HOX back from Carphone warehouse repairs last week.

I was careless enough to send mine back still rooted & with a custom rom installed. I'm sick of this phone so I did't care, as it's always about 20 seconds away from ebay thanks to the bargain basement GPS.

When Carphone warehouse returned the phone, which was sent to HTC for the actual repairs; all they had done was re-install a stock ROM & call it fixed. Bastards!

I took it straight outside for a test & it took 5-10minutes to lock. Still an absolute disgrace.

I had a Nokia Lumia 610 as a replacement phone during the repairs. It worked much better. Only a few seconds for a strong GPS lock & a perfect smooth track. The 610 is about 4 times cheaper than the HOX too.

Still have the HOX tho. I guess I have a little hope they might be able to fix this with a software update.
[HTC One X] waz000000:
mine was terrible!

I downloaded faster fix and changed it Europe and rebooted still pretty bad, I then bought sygic software and it's perfect?!?

doesn't jump and works a treat god only knows why but it just works Google maps was hopeless I was jumping all over the place, try it and see if it works for you. you can get a free one week trail of the market and it's only £17 to buy anyway.

I've used Google navigate for a couple of years now but sygic seriously try it!
[HTC One X] stuart0001:
Sygic appears to be better because it has a much higher tolerance for putting you on the road even if the GPS position is a long way off it.

It doesn't actually improve GPS performance.

Ps. My new phone is still absolutely perfect. Position is always within a couple of metres of true location, whatever app I use, and makes ne realise how good the GPS can be in this phone.

Eg. I was parked in the bay exactly where the position is shown below and it didn't waiver at all over a period of at least 30mins.
[HTC One X] gc48067:
What are the first few characters of the serial no. Wonder if they have fixed the hardware - they were telling me it was a software fault.

SH24L

My previous bad phones were both SH24K

I've also had a good GPS with HT241 (returned for other reasons)

So all April builds but looks like they had an off day in Shanghai on the 19th

I've got another HT241 that I need to test and will post results when I have.
[HTC One X] datta.ca:
Hi,

I am also facing this GPS issue. GPS is all over the place even after getting a lock.

Is it a hardware issue or will get resolved by s/w firmware update? Currently I am on 1.29.407.9

Because I am really scared with giving for repair.
[HTC One X] stuart0001:
Make sure you are in open sky and record a track with My tracks for 10 minutes and post the results. You should repeat this with WiFi On and off.
