[HTC One X] evo6:
Mines the same if i turn it to full brightness you can see the flicker on the transparent screen in the background. Mine only does it when the screen is faded in the background. Its going back today i'm going to test my new phone in the store before i it bring else i'm going to cancel my contract and wait for them to fix it or buy the s3 when it comes out!

Update: Got my new phone and its flicker free :D so far anyway....
[HTC One X] vegetaleb:
I wonder what's the percentage of flickering screens out there!

30%? 60? 90?
[HTC One X] turbox:
Update via OTA to 1.28.401.9

Always screen flicker...
[HTC One X] The-Last-Hylian:
Just updated to 1.28, I swear now the flickering is worse, especially on the image of the snow+sun in stock photos... I'd never noticed a flickering before... now I can see it alot!
[HTC One X] evangeloschr:
Just updated my phone and i see no flickering at all. It seems that its dissappeared. I will be using my phone until the battery drains to see if the flickering appear again.
[HTC One X] DaveDesire:
The flickering seems pretty inconsistent.

I got it this morning for the first time. I was on low brightness and could see it in the settings menu and on the snowy sun picture. I moved brightness up to auto and couldn't see it anymore, I then moved it back to low and flickering hasn't come back... yet.
[HTC One X] franjiepans:
Just installed the update, the flickering seems to be worse. This does make me pleased that I am replacing the phone for another one.

Just waiting for Dialaphone to send me the envelope through.

Such a pain.
[HTC One X] optiknerv:
Just posted mine back to dial-a-phone today. See what I get back and how long it takes. Strange being back on the HD2 :D
[HTC One X] BustaVR6:
Is your phone unbranded? I'm on an older version but don't seem to be offered an update.

I can't decide if I should swap my phone or not, I definitely have a flicker I just wish I knew if HTC will fix it with a software update.

I don't even know what o2 offer with regards returns. My 7 days is Friday...
[HTC One X] lawrence750:
the 7 days is a cooling off period, you could even cancel the contract before then if you wish (obviously returning the phone as well) - i expect o2 will allow you to exchange the device for a new one as well
[HTC One X] optiknerv:
HERE is o2's return and exchange policy
[HTC One X] dengseng:
same here though
[HTC One X] BustaVR6:
Excellent. 28 days for faults. Thanks for the link.

I'll sit tight for a couple of weeks in case HTC can come up with a software update to address it. I do love this phone :)
[HTC One X] d33f:
When your phone is on the charger or when the battery is almost full you don't have any flickering even on the lowest setting, but if you try the same with a lower charge on the battery (let's say lower than 50%) it will start to flicker again on the lowest brightness setting.

At least in my case though
[HTC One X] vegetaleb:
So the update corrected some phones from flickering and other not :confused:
[HTC One X] lawrence750:
just got the exchange. the new one has the flicker as well. typical.

EDIT: now its warmed up, it isn't flickering anymore... it was fairly cold when i turned it on... weird..

EDIT: yes it is. AND it has a dead pixel.
[HTC One X] evangeloschr:
Flickering does happen after the update... Not so often but yes! Going for exchange definately tomorrow!
[HTC One X] cawith:
Just updated aswell, and it's now even worse on my phone!!! :mad:

Well at least I'm gonna get it exchanged on friday, if they have new ones in stock...
[HTC One X] cagdasal:
I updated my phone, still getting some flicker as well. Im going to return it, and wait to see what they do about it...
[HTC One X] turbox:
Yes unbranded (in france). To force update reboot and go in setting to check update.
[HTC One X] evo6:
My replacement still does it. It did not do it when it had a lower charge but know that its got around 75% charge its doing it. Its really weird. And as someone else has mentioned you can see it in the gallery with the picture with the snow...i'm going to cancel my contract, unless I can get a phone with HT24 serial number.
[HTC One X] mrcgibb:
Guys just called up chitter chatter and have been advised that HTC has said to them that there is a hardware problem with the first batch ! Chitter chatter has had "alot" of one x returns ! so anyone with a flickering phone should return it to there retailer and demand the replancement is from a new batch of phones
[HTC One X] evo6:
Which ones are the first batch? Are all the first batch ones that start with HT23 or is that not a indication? I just spoke to my local tmobile store and they have received their second batch but they also start with the HT23 dont know if there is any point me going for a third one!
[HTC One X] DaveDesire:
My battery was full at the time of flickering but it had recently come off charge
[HTC One X] ambrose7:
Just got new 1X, screen flicker is fixed now
[HTC One X] lawrence750:
is it an HT23 or HT24 device?
[HTC One X] ambrose7:
How do i tell?
[HTC One X] Sl1ced Bread:
First post, but I’ve now had three One X’s in 10 days so my observations may be useful:

First Phone: Screen distortion started after a week.

Second Phone: Screen distortion started after an hour.

Third Phone: Screen distortion started after ½ a day. The other banding issue & backlight flickering out of the box. Dead pixel after two days.

I called HTC (UK) who claim to have never heard of these issues. They suggested I should try a forth.

IMO this is extremely widespread. The first phone took a week to display any problems at all and as the phone has been out for less than two weeks I still don’t think we can rule out that this is in all of them.

As I do not know if this is permanent or not I took it back for a refund. I will buy one again if / when the issue is fixed.
[HTC One X] ambrose7:
Oh i see, my serial starts HT24
[HTC One X] :
Flicker Problem Analysis

I think you guys should read this :)

I just got a replacement HTC One X from Amazon today, and I can confirm, there are differences between both of them. Both are set up the same way, and run on the same FW.

1X New -

The screen has a more Warm tone, like the warm setting you get on some HDTVs.

There is no flickering at all.

Everything seems clearer.

Battery is lasting MUCH longer, isn't dying within 20-30 mins of use.

Battery is charging MUCH faster, compared to waiting 2 or 3 hours, from 15% or less.

Signal never randomly stops and restarts.

1X Old -

The screen has a more Cool tone, like the setting you get on some HDTVs.

Flickering in recent apps screen, anything dulled in the background, anything greyish.

Display isn't very clear.

Battery died within 20-30 mins of casual use.

Battery took 2-3 hours to charge from near 15% or less.

Signal randomly stops, and comes on and is unpredictable.

Conclusion & Theory:

My theory is, the lighting used to light the screen is different in my new HTC One X, than my old one. This could contribute to the flickering. And the display quality is a bit better on my new HTC One X; so it is possible the old display of my old HTC One X could be contributing to the flickering.

The other issues I can't say much for except a possible bad batch or poor internal build quality to support the phone's needs.

I'll keep you posted on how my new One X is preforming regularly.

Click Thanks if I helped a little; if this has helped you guys see differences between handsets. I've been here over a year, but never really posted haha.
[HTC One X] tekingenc:
No flickering for me after update.

Welldone Htc
[HTC One X] lawrence750:
could you confirm the serials of both devices? ie ht23 or ht24?
[HTC One X] tekingenc:
My serial starts with HT23
[HTC One X] ambrose7:
On a side note, anyone know how to turn on unlock sounds? mine does seem to make it when i unlock
[HTC One X] lawrence750:
Settings>Sound>Screen lock sound
[HTC One X] ambrose7:
heh, you know what, id been through that screen about 5 times! lol
[HTC One X] turbox:
I've contact HTC france, they said me to send back the device to be analyse but this problem can't be cover by the waranty...

:mad:
[HTC One X] d33f:
What do you mean ? The European warranty normally lasts 2 years.

Or do you mean a replacement phone ?
[HTC One X] turbox:
HTC support said my screen flicker isn't cover by warranty. I must send my 1X to be analyse before repair and ask me to pay or not.
[HTC One X] joplayer:
HTC France are real bastards, dealt with them for problem already, no way to make them hear something.

But there I'm sorry they are completely wrong, it has to be repaired or you have the right to sue them (btw something I'm gonna do this this summer for my HD2...).

I'm pretty sure when they will see it they will understand they mistake and repair/replace it.

Btw you can't do that with the store you bought it from ? 7 days are over ?
[HTC One X] theliquid:
Don't send it to HTC, go to your shop, where you bought your device and say you wan't a new one because of the warranty by law.

The seller has to offer warranty by law, where HTC only offers guarantee under their terms and conditions.

So its far better to get warranty trough your shop. (in Austria this warranty by law lasts 2 years)
[HTC One X] joplayer:
guaranties are complex and probably different considering countries.

From what my store said I have only 7days guarantee for an exchange...

And after that I'm only dealing with HTC. Which is a pretty bad thing believe me...
[HTC One X] turbox:
My 7 days are over (2week). I'm affraid to send my 1X: once they have it they can say :

pay to repare

pay to have my 1X back (for the analyse)
[HTC One X] theliquid:
So you can be glad the France is in the EU and we have quite similar legal system, of course there big differences, but the big legal institutions like warranty are in most of the European countries very similar ...

These 7 days are normally not guarantee, but your right of revocation to send the device back and get your money back (so you can revoke the whole contract - this is the same in all European countries because of E-Commerce directive of the European Union ..).

The right of revocation and warranty are two different things ...

It is lawful that HTC can charge you for their work. You have no claim against HTC to repair your device, because HTC was not your contractual partner but your retailer. You have a claim against your retailer that you get a non-defective device. Normally you can choose between repair and replacement.
[HTC One X] ervin10:
Hello,

I just received my HOX and I'm pretty happy with it have yet to get any problems with flickering. My serial starts with SH23 and it was made in China, it is also running firmware 1.19.707.1.
[HTC One X] joplayer:
Yes I am :) But I don't really know what we could do if HTC refuses to repair the device for this problem...

Yes, the device got a 2 years guarantee. However, the shop will just send the device back to HTC after these 7 days (at least in my case they act this way) and after these 7 days the issue is the same as if you send it by yourself I guess..
[HTC One X] theliquid:
Sorry it seems that you don't understand what I am trying to explain to you.

I'll give it a final try in just few words:

If you got a defective-device, then you have a claim against your retailer to repair or replace your device, of course FREE-OF-CHARGE! How the retailer does it (for example via HTC) is not your problem ...

If you ask HTC directly to repair your device you are under their conditions of their guarantee and they may charge some money for repairing or replacing your device. Against HTC you have no claim that they repair your device free of charge, because HTC was not your contractual partner you bought your device from.

Just ask somebody who knows your legal system a little bit and he will (probably) tell you quite the same as I am trying to do ...
[HTC One X] joplayer:
Got your point now thanks :)
[HTC One X] turbox:
Ok I understand
[HTC One X] saih:
You are getting me a little worried about this flickering.

When I check the brightness adjust screen (at 100%) the grey area around the box has a tiny tiny little flickering - as in it seems like the brightness dims a little and turns the brightness up very little 1-2 times a sec, but it is nothing I notice during usage, only at this particularity place when I look for it. It is from HT23 batch.

It it this you are talking about, or is it much more visible?

And well, just checked the screen while it charged and I would say it was gone...
[HTC One X] mbergan84:
No.. on my second phone it is like that.. it does not go away when charging though.

On my first it was constant flicker no matter which brightness setting it was set to... Much much worse than on the One X that I have now..
[HTC One X] DazNoonan:
Gutted to hear that the 1.28 update has not fixed the screen flickering issue as we all really did think the software update would. This makes me glad my current phone with issues is getting swapped out tomorrow now as I guess it could be a hardware problem after all...?

Will see what my new phone is like, as will give that rigorous testing throughout the first 5 days. Should know a little more either tomorrow night or Friday morning depending what time it gets delivered.
[HTC One X] evo6:
Well I got my third handset today and fully charged it had. I have been running it for the last few hours and it is flicker free thank god. This is the second batch T-Mobile received but the serial still starts with HT.

Like they say third time is a charm and it seems it was in my case. So all I can say is I'm pretty sure its a hardware fault. Best place to check if you phone has the problem is to go the gallery and look at the photo which came preinstalled on the phone with sun and snow. If your phone flickers near the sun then your phone is buggerd!
[HTC One X] Dave Trouser:
Absolutely no flicker on my One X. v1.26 software, and I do get the screen jumping bug and the noise/corruption on the camera.

Screen flickering is looking like a hardware fault - with people getting replacement phones that don't flicker with the same software!
[HTC One X] Sentinel196:
I get a bit of screen flickering if I have my brightness control set to auto, but otherwise it's fine.
[HTC One X] :
I'm not at home right now, but I will check for you when I get home.

My new one has a yellow screen because apparently the display on it is made my Sharp. I'm returning this one too, which is a shame as it's bug free. But I paid for a good screen and a good phone, so I'll continue to send them back untill I get a working device, that meets quality standards.
[HTC One X] justbenice:
I still believe that flicker was software issue because i am having that flicker 2 times already, it was suddenly appear and suddenlly disapper :) . 2 days already and i haven't get any flicker any more.
[HTC One X] :
Download Display Tester on the Play Market, and try the dead pixel test. Swipe it across till you come to Grey, on full brightness. Then I'm sure you will know if the flicker issue has stopped or not.

Sent from my HTC One X
[HTC One X] justbenice:
Just tried it and test it 2 times in full brightness and nothing happen. Even though i'v got flickr screen 2 times already a few days ago. It look like there are something with Sense or other software. Yesterday i flash LeeDroid rom and choice to did not install Sense, after that i use titanium backup Freeze all the no-need software , then now everything work perfect. I am using Go Launcher EX
[HTC One X] nickporwal:
Are you talking about the backlight flickering or random flickering which makes the screen garbled?

I guess backlight flickering is persistence and happens with only with grey colors. it seems with other colors its just hidden.
[HTC One X] justbenice:
I got same flicker as this picture :

But everything are ok now. Never has again after remove sense and all the htc bloatware
[HTC One X] emorej:
I experienced this once and not much as shown in the photos. I think its related with software optimization with the hardware,

i use to get this screen flickering on my macbook after i upgrade to OS lion prior to upgrade did not experience it, anyways im just saying this about mac just to have idea that it may be a software related issue.
[HTC One X] Try4Ce:
That's a software / rendering issue when hardware accelerated apps run and the glichy taskbar is showing activity, like when a message comes in or you have an background app running constantly that updates informations in your taskbar.

It's purely software related.
[HTC One X] turbox:
Since 1.28 when I wake up the 1X, I see a backlight lag.

My backlight is dying?
[HTC One X] evo6:
Yep i agree definitely seems like a hardware fault. My third handset is rock solid i have been absuing it to make sure the screen is ok.

This is the first time I have taken out phone insurance ever because today is my last day that i can cancel my contract with the T-Mobile and they want give me another replacement after today. Could not take the risk........Thanks HTC
[HTC One X] Havoc2k:
my "new" replacement hox just arrived.

its a ht24.... PLEASE dont have any faults. Display und body look good for the first view
[HTC One X] DazNoonan:
If its a fault with the phone that was not caused by you then you do not need to take insurance out. Insurance is purely for any damage that you might accidently do to the phone. You network provider should repair the phone completely FREE of charge should there be any issues with the device (not caused by you) for the full term of your contract.

This is exactly how it happens with Vodafone so I can not see why it would not be the same on other networks.
[HTC One X] evo6:
Yeah thats right m8, but i don't think they have to give you a new phone where as insurance will. I know this because it happend with my wifes phone and Vodefone gave a refurb instead of a new one
[HTC One X] Havoc2k:
looks good till now, no flickering at grey images, not at full brightness not at auto..

let's hope it stays so. one of my favorite games is a simple card game, and it was flickering like hell.

mayhe ht24 devices are really better then ht23 ones. my "new" display is even brighter then the old one
[HTC One X] DazNoonan:
Something must have gone wrong there then. They can only repair your phone, if this is not possible then they should be issuing you a brand new handset.

---------- Post added at 09:50 AM ---------- Previous post was at 09:49 AM ----------

Thanks for the update mate... Hoping mine is from the HT24 batch to be honest as both my previous ones were HT23 and they both had problems.
[HTC One X] evo6:
Yep they could not repair it so they gave her a refurb. I don't want a handset to be repaired if its bloody new! I expect a new one hence why i took the insurance.
[HTC One X] The-Last-Hylian:
I've been pottering about on another thread talking about these issues... I've missed out on what the difference is between a ht23 & ht24 is, what is the difference between the two?

Also how can I find out which mine is?

Thanks
[HTC One X] DazNoonan:
To be completely honest; nobodies knows the different. As it stands less people are having problems with HT24, but this could be because there is less of them.

This info in on the outside of the box on the white slip. You can also find the info in the about menu on the phone within one of the sections in there (I forget the one, and don't have a phone in front of me).
[HTC One X] Foggy79:
In settings/about phone/Phone identity, theres the serialnumber starting with HT23/24
[HTC One X] The-Last-Hylian:
Thanks, I found it.

Settings >>> About >>> Phone Identity >>> Device Serial Number

I'm using a HT23XW103489

1.28.401.9 ota

Got my OTA to 1.28.401.9 this morning and have now noticed a flicker on my screen, especially on the large calendar widget since updating.

Can work around it by turning the Auto brightness off. Asked HTC if this issue would be fixed and this is what there reply was: -

Thank you for contacting HTC regarding your HTC One X.

My name is Robert and I am a Technical Support Agent for the HTC Written Team.

I’m sorry to hear that you are experiencing difficulties with the screen flickering on your device.

The reason for this is because your device sounds faulty.

To resolve this, I would like you to return the phone back to your retailer for a replacement device. As there are no further troubleshooting steps available to help with this specific issue.
[HTC One X] BustaVR6:
In case anyone is interested, this is a copy of my chat transcript when I contacted HTC about this problem earlier today:

Chat Transcript

Please wait while we find an agent to assist you...

You have been connected to HTC Man.

HTC Man: Hi, thank you for contacting HTC Support. How may I help you today?

Me: Hello, sorry if you had multiple connections from me, IE 9 didn't play nice with your website so I've swapped to Firefox

HTC Man: There doesn't seem to be any issues at the moment, how can I help you?

Me: Anyway, I have just purchased a HTC One X, it's a lovely phone

Me: But it appears to have a problem with the screen and I want to know if it's a known issue or not

Me: In certain scenarios the screen appears to be pulsing

Me: its hard to explain

HTC Man: Does this happen under certain circumstances or randomly?

Me: Well it happens all the time, its just more apparent in some scenarios, for example I was just in Android Market and whilst the page was loading, it was very obvious

HTC Man: Does changing the brightness on the phone resolve the issue at all?

Me: No, it's easier to see on full brightness but its still doing it on the lowest setting. I also tried auto brightness both on and off

HTC Man: Have you tried rebooting or resetting the phone?

Me: yes, a few times

Me: I also checked with a friend to make sure he could see the problem as well and he could

HTC Man: We're sorry to hear that your HTC One X is suffering from screen issues we would be very happy to give you a replacement. Please take your phone to the store where you purchased it to receive a swap. Please accept my apologies for the inconvenience this has caused you.

Me: It's no problem, I just really love this phone (and HTC) I had a Desire before this and a Magic before that

HTC Man: I'm glad to hear you are enjoying your phone, HTC appreciates any feed back given from it's customers.

HTC Man: Is there anything else I can help you with today?

Me: No, that's all thanks. Have a nice day!

Thank you for contacting us. To allow HTC to continue to improve our service can I ask that you complete a very short satisfaction survey by clicking here.
[HTC One X] DazNoonan:
How did you get your OTA to that when your on Vodafone in the UK? It's not out yet on Vodafone?

Also I got my third device today and have been using it for the lats few hours getting apps installed and setting it all back up again etc... So far I've got no screen flickering, but it didn't start happening last time until 24/48 hours so fingers crossed on that one.
[HTC One X] freemini:
Just finished reading the whole thread and I really don't like this. I'm just returning my GNex because of the purple grays issue and now I find out the possible replacement of the nexus also has annoying problems(and they're related to gray too). I'm not enjoying swapping phones for stupid screen issues all the time, the Nexus would be my 4th phone I send back because of issues with the screen. I am definitely buying it from a local retailer after reading their terms. At least if I have to exchange it, it's simple.
[HTC One X] optiknerv:
I'm guessing he got a sim free handset on a Vodafone contract through a third party seller such as phones4u, carphone warehouse etc.....
[HTC One X] boccon:
Today I Contacted HTC. They told me to bring it back to the seller.

Excuse me for italian screen capture!!
[HTC One X] RomNoR:
Hi,

My phone started flickering troday -

after i installed 1.28

:eek:

Sometimes i think clowns are working at these companies... :mad:
[HTC One X] vegetaleb:
So it's a software bug if 1.28 produces flickering on devices that didn't before
