Most are, some see it intermittently and some see it only on certain backgrounds. ON my first device it was horrendous and if I used my phone and loooked at the screen for 20 mins or so it seemed like my vision was flickering for a minute of two after I switched it off.

My second one has only slight flickering and it's intermittent, I might even go as far as to say it would take me some time to notice it on this device if I hadn't had it so badly on the first and therefore I looked for it on this one.

My first device was fine for a day or two, then I noticed it flicker very slightly, a few days after that and it was terrible.
[HTC One X] :
Ok, so what do people make of this then?

I've been uming and ahing about returning my H23xxx One X to Carphone as after a few days I noticed random screen flicker. The OTA update didn't fix it.

But, and this is the bizarre bit, a week later it seems to have settled down. 36hrs of pretty heavy use and I've not seen it once.

I honestly don't know WHAT to make of that.

Sent from my HTC One X smartphone which seems to be so smart it has become sentient.
[HTC One X] jonstatt:
Yours is probably like mine. It has to be a very specific scenario, which includes battery level, certain screen brightness, and high CPU activity. I would be very upset if it was persistent all the time like some other owners.

[HTC One X] jpinks:
Just ordered a One X for import to the US. I was wondering if I get a flickering unit will HTC stand behind and fix it? I purchased from Newegg as I know they are a reputable seller. Does that still have 2 yr warranty since its the international version?
[HTC One X] sacredabyss:
Thanks for the clarification OP.

I definitely have the screen corruptions as described on the OP info section. But I am not quite sure about the symptom of back light flickering.

I notice that sometimes hox's screen blink once when i switch to recent apps from any apps or when i was in a app and switch back to home screen. Is this the back light flickering or just normal?

If the back light flickering is a hardware issue, I have to return it and get a new one if my hox have the issue.

Thanks in advance.
[HTC One X] farnsbarns:
That sounds normal to me, just a redraw thing. HTC have not confirmed whether the back-light issue is software or hardware yet. That was the reason for my communication with them and is something (the main thing really) I am hoping for an answer on.

My gut feeling is that the back-light issue is hardware but the lack of info was what sparked this process off in the first place. HTC are being very proactive on this now and I have every confidence that they are doing everything they can as quick as they can.

I will post any response very rapidly.
[HTC One X] :
No dude I mean I haven't seen it AT ALL. Not one flicker in almost 36hrs of pretty constant, heavy use and trust me, I've been looking.

It wasn't there. Then, it was there. Now, it isn't there again.

???
[HTC One X] andpr3:
Interesting. Would be great if you could keep us updated - I know that my phone only started flickering after nearly two weeks.
[HTC One X] sacredabyss:
Sorry i didn't read the OP properly. I hope it's not a hardware issue.:D

[HTC One X] DanteGR:
Could anybody plz tell me if homescreens are flickering if u set the attached image as wallpaper? Thanks :)
[HTC One X] andpr3:
I apologise if I have missed anything in the thread since the above post, but did the Danish rep mention when he would have info from Taiwan for you to post here? If they do in fact know what causes the problem (as per what he told you) then I should hope they would tell us soon rather than keep us waiting.
[HTC One X] farnsbarns:
You quoted it yourself ;)

"He said he hoped he could get some info tomorrow but clearly didn't want to commit to that at 9.30pm, I can't argue with that."
[HTC One X] farnsbarns:
Yes, very slightly visible
[HTC One X] farnsbarns:
UPDATE AGAIN - 27 Apr

Message received just now: approx. 1700 British Summer Time (GMT+1). The two issues he mentions are the screen corruption and back-light flickering.

First of all thank you for your reply earlier today. The content and descriptions were very valuable and I have taken the liberty to share your findings with my colleagues in Taiwan.

It remains a priority for HTC to continue to investigate and work to resolve all reported issues, including any potential hardware or software updates related to your case and to those of any other customers who experience problems. Currently, we are not in a position to provide you with a final conclusion regarding the two issues that you have reported, however we are taking your feedback seriously and have a dedicated team of people investigating the root cause of those issues. We are more than happy to provide you with further updates when we have them however, before we do this, it is critical that we have all of the facts. HTC remains laser focused on delivering a high quality experience to our customers without exception and we appreciate your continued patience whilst we work quickly to address this issue. We anticipate being able to provide a more detailed update early next week. In the interim we encourage any customer who believes that they have a faulty device to contact HTC directly for resolution.

I like "laser focused" and "dedicated team"...

I think we're getting somewhere here, very promising.
[HTC One X] andpr3:
I read back and forth in the thread and got confused about the dates - sorry! So that means he should already have gotten the info - I am thinking of the time difference - it is now actually the 28th in Taiwan as the time is two minutes past midnight. I do hope he will get back to you today...

EDIT: I see the reply came up while I was typing this...
[HTC One X] farnsbarns:
We cross posted there, see the post above yours. Not today but hoping for early next week.
[HTC One X] Huey85:
Just tried recreating that graphical glitch in the notifications bar as per your instructions but wasn't able to - pulled the bar down and up and down and up for about a minute and still no glitches. Then opened up the camera and no corruption/glitches either.
[HTC One X] joplayer:
I'm more and more worried by the fact they keep delaying telling us what the problem is.
[HTC One X] farnsbarns:
Sounds like you missed this...

Now pull it part way down but keep hold of it (Keep finger in place).

Move it back up to the top but don't let go (Keep finger in place).
[HTC One X] MarylandCookie:
I think it may make a difference where you place your finger to drop it down from. I think it should be near the time, drag down and then back up slowly, im pretty sure most if not all have this issue, its just that i reckon not all have recreated it "properly". I.E tried a couple of times and assumed it didnt exist.

I actually tried this on my 2nd and 3rd handset both initially didnt have it because was dragging the bar down from the centre and off left, once i started dragging it from the right by the time thats when things got ugly lol
[HTC One X] Huey85:
Nah, I did that too.. just didn't bother repeating every step that you mentioned in my response.

EDIT: okay, so I tried it another time but muuuuuch slower upon the upwards closure of the notification bar and yes I do see a slight graphical glitch for a split second, but only in the part where it has the date - my other items in the notification bar (i.e. time, etc.) remain uneffected.
[HTC One X] MarylandCookie:
Thats the main glitch :)
[HTC One X] jonstatt:
Personally I find this a very contrived scenario and I am not worried about it. I am only worried about flickering because it is not clear if it is resolvable or not.
[HTC One X] farnsbarns:
There you go, You can see how this would happen in normal usage on occasion (ie, not trying but haphazardly) . After it has happened, open you camera.

Don't forget, there is a different issue, the one the fuss here is about, which is the back-light flickering. That's the one that concerns me most.
[HTC One X] Huey85:
Same here - it isn't a major worry for me. If my screen was flickering on the other hand, then I'd be going out and breakin' shins.

---------- Post added at 02:36 AM ---------- Previous post was at 02:34 AM ----------

I did open up the camera and it worked perfectly fine. Didn't see any issues. I'm on 1.28 ROM btw if that matters.
[HTC One X] oxfordmark:
Got my replacement, charging so I cantsee any flicker. The volume buttons are a bit loose.

This ones a 114xxx, before I had a 135xxx

So an older model.
[HTC One X] Htc_One_X:
EDIT: Found where to look mine is indeed a HT23*****

Set as wallpaper, no flickering, mine is intermittent, however IF and ONLY IF it gets worse I'll get it replaced. Yes it can be eye watering but for me atleast it rarely happens. How do I find out what batch mine I'd from, and I'll report back. Karl
[HTC One X] mertzi:
that had a little more substance, still not convincing. If you feel like it, can you ask him if this: "we encourage any customer who believes that they have a faulty device to contact HTC directly for resolution" means that instead of swapping faulty devices via the retailer you can do it directly through htc? And if it is so, ask if that applies to the whole EU. I'd rather avoid making another DOA through Three sweden as they really messed up with my first DOA canceling my contract, then sending me an iphone 4S which was delivered yesterday and I'll have to send it back before getting my second HOX. I sent the first one back 2,5 weeks ago.
[HTC One X] farnsbarns:
HTC's policy is not generally to replace phones but only to offer a repair. I know this after extensive conversations with support. I'd suggest getting on to support (in the UK the phone support seems much better than the online chat) and explaining your problem and the trouble you've had with your network. Can't hurt!

I don't feel comfortable asking them, I don't want to them to think I'm abusing the relationship I have found myself with.
[HTC One X] pewpewbangbang:
Yea...I called them. Their warranty customer service was a joke. Guy didn't seem at all interested or capable of solving my problems. He told me to charge the battery the way the manual says it because its a lithium ion battery.....I'm just like you are an idiot in my head. I called saying I had battery problems, overheating, and screen flickering. He told me charging the battery correctly would solve all of it....I was just like wtf? It hit 60 degrees celsius and said it was overheating in battery information.....

Anyways, after all that...he said to call back if I still had problems and they would send it in for repair which takes 2-3 weeks....I don't have that kind of time without a phone damn...

I'm hoping theres some way of actually getting a replacement
[HTC One X] freemini:
Pathetic, that's all I could think of.
[HTC One X] toonhead85:
I want to thank the OP for all of their hard work. I too have issues of this nature and would love it to be a software issue so I can get back to not worrying about my device being "defective".

Thank you so much,

[HTC One X] g00n3r:
Hmm, well after a break of nearly 4 or 5 years from HTC (my last HTC was a Tytn 2) I bit the bullet today and purchased a One X.

I gave up on HTC previously due to their bad build quality and poor aftersales, I really hope things have improved, fingers crossed my 1X has been perfect so far.
[HTC One X] :
I'm in - Darren McFarlane, UK.

I KNOW for a FACT the hardware is faulty after some tests I have done on over 11 phones (13 to be precise). They can't deny it.
[HTC One X] farnsbarns:
That could be useful, what tests have you done and what were the results?
[HTC One X] smoke2:
Also mine it has from time to time.

It looks like that some component has the same frequency as backlight of the display.

Oh, and it looks like that every One X suffer for this kind of problem.

HTC definitely must solve this problem!
[HTC One X] HaTeC:
"HTC remains laser focused on delivering a high quality experience to our customers without exception"

" In the interim we encourage any customer who believes that they have a faulty device to contact HTC directly for resolution."

HTC Doesn't give a **** about me as a consumer if they want me to send the phone for repairs and wait 15 days for it to maybe come back fixed.

I am done eating these lies, after talking to them yesterday i have given up.

They release these worthless messages to a forum while at the same time telling the support lines to not give anyone anything beside the 14 days DOA and 2 years repair service.

It's all bull****.
[HTC One X] smoke2:
Agree, we must together force HTC to solve this problem and tell us whats going on!
[HTC One X] :
I got irritated and exercised my rights to a replacement on the spot if I was given a faulty phone in store. after 10 phones straight, ALL featuring pretty much all the faults you can name in this forum, the 11th one worked with no faults, no flicker, no signal drop, no internet cut out, no fast battery drain, no dead pixels, no UI corruption (yet), no yellow screen, no colour calibration at boot problem etc - No issues at all. But every One X previous to this one, featured more than one of the faults. This was for my brother today at the Carphone Wearhouse. I have had Two from amazon and they both were just the same. Along with all other statistics, all retailers have bad batches with hardware faults.

Having experience with internal works of phones, these faults can only be caused by hardware and hardware only. It's a fact. I've also examined other peoples devices opened, and I think personally, the build quality inside is very poor. The phone shows physical signs of struggling and not dealing with it's own hardware correctly.

HTC are a business that have to keep a reputation. They will use a common tactic of "playing possum" to the consumer, and retailers. They act like they are not aware of the problem and avoid properly answering, every way possible, even when directly contacted, they play us for stupid because they can. This is a business strategy. As soon as they release a working batch, that will only be when they start to speak and focus 95% of the attention on the new batch that works, but still not openly admit to it being faulty hardware and poor build quality for the previous phones. The company sees this as putting a plaster on the wound, and they are simply exercising their power of control here.

By doing this, it statistically doesn't damage their reputation and the issue will be forgotten.

Whereas if they came out and admitted "Yes, we released a faulty batch of phones with faulty hardware", they will lose points statistically and lose company respect, and will receive immediate attacks from consumers, and most importantly retailers where they will lose reputation with (say for instance, Amazon might pull the device from its store and this would hurt HTC financially, and make them less likely to sell their products).

That's the truth behind all this. That's how business works.

Sadly, we have no power over this. We have to wait. If anyone REALLY wants this phone, I can only recommend people buy the phone from a shop, in store, and test the phones for all the listed faults, and keep replacing them in store, until they find a phone that works. As I said before, I had to test 10 phones before I got a faultless one (Sadly not for me, but my Brother).

I'm going to wait a month and see what happens. I really want the One X. If another phone that matches it comes along, I'll be buying that.
[HTC One X] pewpewbangbang:
Look no further than the Galaxy S III haha

but yea, still not sure how you can guarantee its hardware. Well at least the flickering portion of it. Yellow dots and stuff seem like hardware but flickering only on light grey color, seems to me like it could be bad GFX drivers from Nvidia as it's only affecting that certain color, not dark grey, not white, just light grey.
[HTC One X] farnsbarns:
Ok, well thanks, I appreciate the time but I did think you had done some test and proved it was hardware. My gut feeling is that it is but proof would be the holy grail right now. Shame, thanks for the long post though.
[HTC One X] diegosps:
Sorry to ask, but i am one which didnt fully understand that.

Is the problem showed in this video the screen corruption?

[YOUTUBE]r8yuKi8nzV0[/YOUTUBE]

From what i read, i believe it is. I have this when in low battery.

But what exactly is the back-light flickering? Anyone have any video of it?

I tried to reproduce it, whatever it is, in gray battery stats screen, but nothing happened (thank god).
[HTC One X] DanteGR:
Hello.

Yes the video u provided displays the svreen corruption problem.

The screen flicker is illustrated in the below video on a macbook but it's about the same on out HOXs.

Hope this helps :)

http://www.youtube.com/watch?v=ENxqjxzuht8
[HTC One X] pewpewbangbang:
Wait....is the whole screen flickering for you guys?

Only the actual color light grey flickers on mine, all the other colors and screen are fine when it's happening.
[HTC One X] DanteGR:
Personally for me it is very intermittent as i wrote previously. Only on apps with dim white color like tapatalk, whatsapp, default messages and people app etc and only in low brightness. In full brightness all is fine.

The video link i provided above is only for illustration purposes for the poster above me to understand what we are talking about :)

But for me in tapatalk for example if the light flicker starts then it affects the whole part where the screen is dim white. Not only parts of it.

This is really messed up man. I Believe every person has it in all different circumstances and occassions.

I have read others have it on full brightness, others on low brightness, others in light grey volor, others (like me) in dim white ones and others on all colors..

What a MESS!
