I don't know if this has been said.

But HTC had send the "how to" fix to the repair centers. (26/06/2012)

The solution is "4 extra Polycarbonates are attached on the main board".

Description:
This Service Advisory aims to fix and prevent WiFi poor signal caused by deformed of antenna spring.

Condition(s) to follow this service advisory:
1. When customer complains about WiFi poor signal
2. When device is disassembled for level 2 repair or above;

To clarified root caused of WiFi Poor signal:
1. Compare the wifi signal of customer device with a good device. (Both devices should connect to the same WiFi AP/Router)
2. Observe user’s device’s if having low WiFi signal.
3. If the device has poor WiFi signal, check whether antenna spring is deformed.
I. Press and hold the back side of bezel as location indicated.
II. Observe the WiFi signal while pressing the back side of bezel.
III. If WiFi shows better signal strength (Has enormous improvement), there is connectivity problem due to antenna spring deformed)

Thanks for this, great info I will add it to the OP when at my PC.

Do you have a source for the info?

Cheers,

Oliver
[HTC One X] xmoo:
If I tell you my source for the info, I won't be getting info from my source anymore ;)

For now, this is it. Even with the whole "how to"... it's still better to let a repair center do it!
[HTC One X] ToddeSwe:
A picture of the "fix" would be nice :)

THanks for sharing.

Love the way they say to clarify whether the device is faulty or not is to follow the steps outlined since the very beggining of this thread lol :laugh:
[HTC One X] Bubba Sher:
I got my phone back on the 21st June, so maybe they didn't apply this fix. Should I send it in again as that fix lasted 9 days? Of course there's a possibility its the same fix applied on my phone!!
[HTC One X] xmoo:
There you go.

Remember I do not own this document!
[HTC One X] ToddeSwe:
Really hope this will stabilize it enough :)

Would be even nicer to know from which sn this fix is applied to originality. :)

[HTC One X] xmoo:
This has been said like a million time!!

The freaking SN does not matter, this applies to all SN HOX!
[HTC One X] bigoliver:
Yeah me too, I would like to think that our input on this thread has played a big part in HTC discovering and fixing the issue.

It is great to know that HTC listens to it's users. I think how HTC have handled this design oversight has generally been very good, just slightly let down by slow communication between them and the repair centres. I dare say that with many other manufacturers we would all still be waiting just to get the fault confirmed.

Generally the phone retailers have not performed so well IMHO.
[HTC One X] bigoliver:
The fix looks like it is designed to prevent contacts from being flattened, it seems like it should do the trick. If there is less space inside the phone, would this increase heating or would this just be minimal?

How does this fix look to everyone? As always, leave us your feedback :)
[HTC One X] Chad_Petree:
It should matter, there should a point whereHTC started to include this fix from their factories, i have a hard time believing they reopened all their phones to implement this fix :(
[HTC One X] bigoliver:
I think you may both have your wires crossed. HTC have said they fixed the issue on the production line, I think ToddeSwe wants to know which serial numbers have the fix implemented at factory level as standard. xmoo I guess you know someone who works in a repair centre and leaked the info and therefore would probably not know which serial numbers where manufactured with the fix installed (Though with time I'm sure it will become obvious).

Thanks for your information xmoo, it is very interesting and useful.
[HTC One X] xmoo:
If you Google wisley... all the information you need is available.

Sometimes you do need to translate it.

These chineese forums are filled with a lot of info and files ;)
[HTC One X] bigoliver:
Did you (or anyone) ever find out about this serial number? I am curious :confused:
[HTC One X] Henkjoost:
updated my post mentioned in the OP.

I have to pay €40 to sent it back unrepaired. Can't do anything els. Don't have €350 in my pocket.

HTC said: Dynafix need to change your motherboard and casing of the phone to get your phone back under warranty. that's why you have to pay €315.

So when my phone is back home for €40 warranty is still voided.

Manufacturing fault? no..no.. unlocked is just NO warranty.

HTC don't care, Dynafix just doing their work and keeping the procedure HTC explained them. Belsimpel.nl sending me to HTC, don't care much either I think.

:crying: < well not yet,
[HTC One X] bigoliver:
Out of curiosity, did you relock your bootloader and reinstall the original software before returning the phone?
[HTC One X] stuart0001:
It wouldn't matter. Bootloader will say relocked and HTC will have a record of the serial.

I would ask why it is physically necessary to replace motherboard to fix the fault they have admitted is a design issue.
[HTC One X] Henkjoost:
Ofc I did, stock RUU+stock rec.
[HTC One X] bigoliver:
Hi,

I just read your story again with update. It is unbelievable that a company dare try charging you for a fault caused by a design flaw that was there before you even bought the phone from them. In the UK we have ofcom who are great at resolving this kind of issue, do you have a similar body in Sweden?

Did you manage to get the details for the ceo's office they may be more helpful.

Also try getting some local publicity in Sweden, email a few tech sites and your local paper.

If you do end up having to put a legal case forward you could always represent yourself to keep the costs down, if we all work on it I'm sure we could come up with a very strong case for you to put forward.

Thanks for keeping us informed and I hope you get your phone back asap
[HTC One X] ICO187:
ok got mine back yesterday.

Repair Details:

Inspected & chemically cleaned contacts.

Unit tested on air on calls in & out sucessfully.

Upgrade software 1:29:980:11

Unit charging correctly.

Unit tested serviceable.

still no wi-fi :(

just try this check:

ok next i opened my modem settings (i have a iCONNECT Access 624W wireless router)

http://192.168.1.*** > Modem username > password > wireless > Management > Access list.

i re-applied my mobile Mac address

Apply > Save Restart Menu > Restart Access Point & close page

bingo FULL strength wi-fi :victory::good:
[HTC One X] bigoliver:
So after your wifi antenna fault was repaired your wifi still had another fault or developed another after the fix.

It goes to show that after the fix, if WiFi is still faulty don't assume it is the same issue, after the official fix I doubt the squeeze test will still work so it will be much harder to diagnose.
[HTC One X] Shobhit Agarwal:
Getting hox replaced!

Hi

I had the same wifi signal strength issue, I gave it to the official service center and called the HTC customer service line.

Firstly they said the phone will be repaired but now they informed me yesterday that the phone is going to be replaced.

Let's hope the new one works!

*******

[Update]

They replaced my phone and gave me a brand new phone and it is working fine now. The WiFi doesnt drop off and I live with two persons who have SGS2 and my one x rules over them.
[HTC One X] RazerRazer04:
How about starting a web page with all info collected and a petition so HTC will finally do a replacement program like apple did when they had faulty mag safe connectors?
[HTC One X] ICO187:
correct the squeeze test did not work after it was returned BUT it never worked for me before either.

but after i deleted my mobile Mac address from my modem/router & re-installed it it's worked all day so far with no drop off ....... fingers crossed :rolleyes:

NOTE: all my HTC cell phones have connected to wi-fi via scan BUT my One X i had to manually enter my cell phone Mac address to my router - no drop off since...........

Could you update the change log on the first post please? :) Just so I don't need to look through loads of pages on the thread aha :)
[HTC One X] bigoliver:
All the important stuff I have added to the OP already and marked it as update, but I'll do a change log when back at home.

I'm in Bath for the weekend with my son watching The Amazing Spiderman will be back home late Sunday Night
[HTC One X] boe323:
Just a quick update, im on my 6th phone, all batch numbers were and still sh25, its been just over a week i thinksince replacement and all good, perfect gps, decent wifi, but crap 3g so i purchased a sure signal box. Mt phones been getting really hot sometimes and i was expecting the wifi to develop the fault, so, so far so good.

---------- Post added at 06:10 PM ---------- Previous post was at 05:53 PM ----------

I think that back camera not centered is part of the design, all my 6 handsets had and have the camera lense slightly to the right underneath the protective glass.
[HTC One X] jetsetwilly:
Well HTC have had my phone for about 3 weeks now, I think they're still looking at the pictures of the mrs and have forgot what I sent it in for (probably should have wiped it first). But life is simple now with my Nokia e5, I don't feel the need to pick it up every few minutes or check for new roms. In a way, my life is better now. Thanks HTC. :-)
[HTC One X] boe323:
Actually, if you look closely at the back camera youll see its a kind of illusion, it looks of centre but its just the shadowing, obviously its not going to be spot on dead centre because of the cover, but yeah, its just the shadow makes it look of centre.
[HTC One X] p4nts:
Gah?

Okay so I have just received today an HOX as replacement for an HOS [long story - it's the so far unacknowledged parallel to this one :-( ]

The phones serial is HT23XW - brand new from Carphone Warehouse. But from reading this thread this would seem to show that the phone was manufactured at the end of March 2012.

At the moment the WiFi seems fine. From some of the recent messages it would seem that I should hang on till it's clear what serials the fixed models have?

Or should I go back tomorrow and ask them if they will change it?

@bigoliver what serial does your "new" one have?
[HTC One X] Henkjoost:
Well I would like to help all the swedish people out here :)

In The Netherlands we have something called 'Het Juridisch Loket'

you can have a 10min. talk and explain it all. When you need more information you can fix an appointment with one of the people working there. Guess that is my next step?

Not getting any names or phone numbers, they are just escalating my messages.

[HTC One X] boe323:
Sorry, not quite sure what you mean, but i meant that ive had 6 replacements, not that i have 6 at home, my 6th is the one thats working, sorry if i confused anyone.
[HTC One X] bigoliver:
Sorry, I didn't get a new HOX, I swapped for another brand. I do miss my HOX though :(
[HTC One X] p4nts:
Oh I see what did you switch over to an SGS3 :-?
[HTC One X] lnoormohamed:
could mean its a refurb model.....
[HTC One X] boe323:
why does the galaxy s3 outperform the oneX? is this another hardware issue?

---------- Post added at 10:06 AM ---------- Previous post was at 10:05 AM ----------

Not meaning benchmarks> just all round smoothness and speed and the game play.Also, why isnt there a gpu ui to control the graphics and gpu performance? is there a reason to no gpu ui?

---------- Post added at 10:15 AM ---------- Previous post was at 10:06 AM ----------

Oh yeah, one mor question, the people who are developing the wifi issue, are you putting the phone in your back pocket or somewhere where the back can be squeezed, i cant see how it can be squeezed by holding it, so how are the contacts being bent? is it the heat making them weaker? These phones do get crazy hot when using for a long period.
[HTC One X] PMaksymiuk:
So which serial numbers experience this bug?

I have a SH24Y that i think is a-ok if it matters to anyone.
[HTC One X] boe323:
I dont think it matters, just seems to affect some phones out of each batch number, HTC have fixed the issue but we dont know the batch numbers, we think it could be sh/ht26 and up.

---------- Post added at 10:28 AM ---------- Previous post was at 10:22 AM ----------

Ah, wait, i have an idea how the wifi issue may develop, the battery and phone are stuck to the back cover right, so what if they were to come unstuck because of the heat, then the back case would no longer be pulled tight against the contacts, and if the contacts were bent when putting th back case on and pressing it to make sure they stick then this would be the cause maybe?
[HTC One X] irharrier:
I think your are VERY right and I BELIEVE my phone wifi was great at the first but

after a few overheats(playing hd games) it become worse and worse
[HTC One X] bigoliver:
I have had a few theories, I have noticed that adjusting volume or entering bootloader requires you to kind of squeeze your phone at the top, I think this could misshapen the body enough to separate the contacts, especially if phone is hot. If you try to enter bootloader you will see what I mean, a lot of pressure around the antenna area.

I have a universal car dock that today I noticed works by squeezing the sides of the phone to hold it in place, I did wonder if this contributed to the issue.

Also maybe the phone gets the contacts squeezed whilst in your pocket.

Maybe a tight fitting case has been causing the issue, the sticking some folder paper behind a case and the phone has been reported to slowly make the issue worse over time. So many theories.

I will say that I never dropped my phone and really looked after it, I did have an unofficial case on my phone from day one and use an unofficial car dock but neither appears to do anything that should cause such an issue.

I think it has been officially reported that the squeeze test can accelerate the issue but it has also been confirmed that HTC advices official repair centres to do the squeeze when testing for the fault.
[HTC One X] liberator72:
Whilst I agree the phone can get pretty hot at times, especially playing games, I cannot agree this is the cause of it. My brother has a HOX and has had his since launch week in the UK. His kids play HD games on his all the time and he has no problem at all with his Wi-Fi. He has a HT23 model, perfect in every way and is used to watch videos, play games and just about everything else the HOX is capable of. I had a HT24 model which I got at the start of May and only ever played Zen Pinball THD once on it just to see how it was. Played that for about 10 mins and got bored so uninstalled. Never once did I experience my phone overheating and in every other way the build quality was flawless. Still after just a few short weeks I could not connect to Wi-Fi unless I was sat right next to my router. So no, I can't agree i's down to heat and is more likely to do with the polycarbonate back shell being too weak in certain cases, which then bends to push on the Wi-Fi antenna contacts which in turn are not springy enough to bend back. This has been discussed earlier in the thread, and those that have opened and repaired there phones themselves tend to have the same theory AFAIK.

Edit: The worst I have ever done with my phone is to put it in my jeans pocket (never back, always front) and I suppose if the back case was indeed a bit week, the pressure with it pushing on my thighs could have pushed the back case bending the contacts. Who knows, it's all just speculation really.
[HTC One X] copers:
I have a HT24 and my wifi seems poor. See screenshot below taken in same room as my router :

Constantly switching between 2 and 3 bars. My desire HD stays rock solid at full bars. Squeezing phone does appear to improve things. This seems to be the problem discussed here but perhaps not a bad.

Should I be returning it? All good otherwise.
[HTC One X] irharrier:
you are right but I thing overheating is ONE of issues that can cause this sh!T :D

and i have to admit other than overheating worse thing that I have done to my HOX was putting it in my pocket and squeezing it against my body:D

BUT let's not forgot that this is ALL HTC's fault not ours.

yes,indeed.

now it switches between 2-3 next week it could get worse and switch between

1-2 :D
[HTC One X] ste1164:
Bit off topic but what brand did you switch to?
[HTC One X] danio40:
Hi All,

I had a same problem with WIFI and read this thread.

then I decide to repair on my own risk with video tutorial.

I did exactly what I saw and the signal strength wasn't good (no changes) so I decide then to solder one more wire to make both connections and voila max. signal strength. Now my HOX is working as I wanted.

:laugh:
[HTC One X] Henkjoost:
Yeah, I did understand you, ;) changed 6 times. I'm strugling to swap it just once. Haha.
[HTC One X] Starky09:
Hi,

I'm also affected by this bug and I want to send it back to HTC for repair. Now I wanted to put the device back to factory default by restoring my Sense-ROM, but I only get the message "MD5 Mismatch" in CWM. Did I do anything wrong and how do I close the bootloader again?

Thanks in advance
[HTC One X] ToddeSwe:
Go to your ROM thread and ask how to go back. This thread is for the WiFi-problem only. Good luck

[HTC One X] tasos12:
Hi all!

I will upgrade to One X in a month or two.

Is there a way to know if the One I get will have the problem or not?

Is there a batch number after which the problem is fixed(I have heard that HTC admitted the problem and said it will be fixed in the next batches)?

Can I know right away if I have the problem so I dont even have to leave the shop and have it replaced right away?

Thanks in advance
[HTC One X] copers:
Thanks vkvedam - thought so. I have the phone on a business account so hopefully they will just issue a replacement rather than repair.
[HTC One X] ToddeSwe:
I would look for serial number that starts with SH27 or HT27 just to be sure that you get the fix built in from start.

Change Log 09.07.2012

Since the last change log I have added to the OP..

[1] MAIN NEWS xmoo has leaked the official HTC repair guide and even a picture of the repair, this is information is only intended for the repair centres, NOT as a home fix! See the recap below..

Photo of the official fix

[2] I have added Henkjoost's incredible story to the OP see here. He keeps the story up to date and would appriciate any help and advice you can offer. Henkjoost have you emailed the Belsimpel.nl CEO's Office yet? The law around returning goods is similar in all European countries, if HTC won't fix your phone that is not your problem, I believe Belsimpel.nl should fix this for you as they have a responsibility to their customers whether they end up out of pocket or not.

[3] My guide to returning your phone for a Replacement, Refund or Repair added, read it here If you can add anything to the guide or offer feedback then please do.

Ok now for an update on the campaign and a little good news..

Quite a few members have had their issues resolved, including me. I feel this has been a result of everyone contributing to this forum and getting the fault know to HTC and repair centres. True we are still getting a few horror stories (Henkjoost story above is probably the worst I have read & is still ongoing) but things seem to have improved for the majority. If you are still having problems please let us know, I am happy to add further horror stories to the OP.

HTC have implemented the fix mentioned above. No one has given any reasons why the official fix should not resolve the issue for repaired and future models. If you can see any potential issues with this fix please let us know.

This thread has slowed down a little which is hopefully an indication that the issue is getting fixed, though it could also be because the thread is getting less media attention.

The outcome so far is looking good, lets hope we continue to see improvements and we can all start enjoying our phones without worry. :victory:
[HTC One X] chimo29:
Further to my last post, I rang HTC today and because they had to manually book my phone collection with UPS, It turned out tehre was no return booking made. So they were lost on the phone and put me on hold. They finally came back and had to say that they didnt know where my repair was at, All they could say was that they know it was signed for on arrival, nothing more.

So... a brand new 500 euro phone in for warranty and possibly lost.

She said she's going find out and ring me back which I feel wont happen. Its always a brick wall when I ring.

Then I asked her if she knew of the issue and that on XDA there is so much talk of it. her answer was that HTC dont believe what the forums say and have to make up their own mind. Surely in case, its overwhelmingly obvious.

Anyway fingers crossed I'll have it back by the end of the week, if not, i'm not going ot be so calm about it.

Chimo

it's called 'Het conformiteitsbeginsel'

and

and

I tried it both at Belsimpel and HTC

Thanks for trying to help me out anyway! could sometimes really use it.

Big er is helping me out big times.

same answer for you I guess

and I didn't speak the CEO from Belsimpel myself, but my contactperson asked him and it changes nothing she said. again: warranty lost etc.

try to speak the CEO of HTC NL but the contactperson from HTC, Susan, could not let me talk to him because: it changes nothing.

:rolleyes:

damn I think they are b*st*rds :(

The only problem for me was the bootloader.

Otherways it had been fixed and I allready had my device back home :)

but than... I simply have the right for a proper device. I asked HTC and Belsimpel both for it.

well you know the rest of the story
