:mad: CAN SOMEONE PLEASEEEE update me on whats happened/happening with regard to the htc one x screen flicker????? happened to me on day one of owning the phone - sooo disapointed. retailer i brought it off took my money then didnt want to know about it when i tried to return 2 days later. htc told me to send it back and they will investigate! when i asked htc nz if they were aware of the problem she said she didnt no... are there any updates etc ie the 1.28 from 1.26 (ps what does that mean and how do you do it)

im quite distressed, spent ALOT of money on this flawed phone - and sold a perfectly good samsung galaxy s2 to get it!!!
[HTC One X] bigoliver:
I have screen flicker too, was there from start, not sure it its getting worse or my eyes are just more acustomed to it now. I I have a grey 3uk branded phone with the 1.28 update, not sure if screen is acer, Sharpe or another brand, how do we find out?

Also, does anyone know long do we get to return the phone if not fixed via software? Had mine a month now :(

Thanks,

Oliver
[HTC One X] freemini:
Are you sure there is no law that allows you to get return it? In Norway it's 14 days, there must be something similar, you had it for just two days..
[HTC One X] Eggcake:
At least one panel is from Sony (according to Anandtech).

I also have the flicker, but not constantly. It doesn't annoy me that much, but I still hope this gets fixed.
[HTC One X] Harnec:
Isn't latest news htc found out that this is a software problem and it will be fixed via OTA (according to the first page, 2nd May update) ?
[HTC One X] P1n3apqlExpr3ss:
I'm guessing you got yours from Telecom? They still haven't gotten the 1.28 update (launched with 1.26), as for the screen flicker apparently it is software related and be patched soon
[HTC One X] leith51:
Just for your info I have now had 7 YES 7 one x from t-mobile I have 2 lines on my contract, out only 1 did not have screen flicker but all of them had screen corruption not only that they also had problems with scrolling in browser as it just went blank are parts of screen disappeared. I have been returning the phones every week ( within the 7 day period) I have been a loyal t-mobile customer for well over 10 years.

But I finally gave up after the last exchange when then sent me a refurbished phone which within 24 hours it was the worse faulty phone I have had they only offered to send it for repair, after an hour of arguing they finally agreed to let me return the phone and return to the previous contract before the upgrade was done 30 days ago,

That evening I then ordered a new one x from carphone warehouse and less than a few hours later the 1.28 update came all it did was make the bad faulty phone worse and made this one not much better.

I will never use t-mobile again

i will test it bro when i root, i'm waiting for the Asian WWE 1.29 OTA or RUU before i root my device (since as you know we can't update the partitions from recovery)

thanks for your work, what did you mean by color? did you disable PRISM? :D

If it works then you will have all the flickering girls of XDA at your service :D
[HTC One X] double_ofour:
Flashed and Booting now.. will post a feedback after... hhmm.. 5 to 10mins?.. we'll see..
[HTC One X] double_ofour:
Ok, heres the result..

Before applying, i first made sure that the flicker is visible by going to birghtness setting. I flashed the required files after confirming that the flickering is visible right now, after booting i went to brightness settings and the flickering is still there, however, when checking/unchecking the "Automatic Brightness" -->> phone restart.
[HTC One X] :
Ill throw another one up later, it should fix or reduce screen flicker, ive had it tested on another device before

[HTC One X] seanmccluskey:
I think the flickering issue is to do with the actual hardware, my original HTC one X had the issue, I took it back to my local store and swapped it for another and there was no screen flickering.
[HTC One X] twistedh:
Do it mate, if you can get the flicker sorted, then you'll attract a wide audience from the start to ensure enough interest for future updates :) Looking forward to it!

[HTC One X] ShortOnMyDo:
Touching the screen on both sides resulted in grey spots so I disided to have it repaired just to see what happens. Within two weeks it came back with a new screen. And yes, the flicker is still there. But only when battery is low. It's something that I can live with. So many other things makes this phone just great, so I lea e it this way...

Btw. Still have that screen flex problem when touching the screen at the sides....
[HTC One X] vinegarjoe:
Thanks for that craggy. Its got to be a hardware problem, lets hope it is indeed fixable with a software update.
[HTC One X] :
lol, software problem my anus!
[HTC One X] Nubzori:
I really hope they fix it with software update, I have slight flicker with low brightness but it doesn't bother me that much to send it back. Simple software upgrade from HTC and Nvidia (if it's power management issue) please :)
[HTC One X] pewpewbangbang:
Why can't it be software? What kind of flicker do you have......I have flicker only on certain shades of light grey and at maximum brightness but even then it's not horribly noticeable. I'd point at software as Asus prime had same issue and it was solved thru software. Plus why does only the light grey flicker and none of the other colors?

If you've read through the thread and others on the 1X XDA forums you would have seen talk of the nvidia Prism technology in the Tegra 3 framework:

http://xdaforums.com/showthread.php?p=25601595&highlight=prism#post25601595

http://xdaforums.com/showthread.php?p=25612847&highlight=prism#post25612847

Basically, Prism tinkers with the backlight and pixel colour intensity on a frame by frame basis and is part of the power management features of the Tegra 3 platform, all controlled by software drivers.

The Asus Transformer Prime was the first device launched I believe with the Tegra 3 and Prism technology, and it had a very similar screen flicker problem that is well documented online, and it was fixed with a software update.

I 100% believe this is the same issue manifesting itself in the 1X, and that it will not exist in the US dual core CPU version of the handset.

If you can hold out for more info in this thread and a big software update in the near future from HTC with driver fixes in place from nVidia, I am sure all the screen flicker issues will evaporate away and we will wonder what all the fuss was about!

Thanks for that, your post is really encouraging!!! Ive been wondering whether or not to return my phone but your post has convinced me this is something that can be resolved with a software update. Great news indeed!
[HTC One X] vinegarjoe:
Sorry to bother you again but Ive another q:

It relates to point 2 that Trev made: "Very fast and consistent flickering that affects greys. When you look at grey colours, it's sometimes like looking at an old CRT monitor with a poor low refresh rate. I DO observe this problem on my phone, and it is not constrained to low brightness. You probably could not show this in a YouTube video. Another camera would not pick it up"

Is this also a software issue? This is the main problem I have.
[HTC One X] twistedh:
This is the whole issue most of the thread is about. It is a software issue.
[HTC One X] vinegarjoe:

thanks!

Please, please, please read back through the thread and you will find answers to your questions and concerns, I replied with a description of the cause of the flickering only 2 pages back:

http://xdaforums.com/showthread.php?p=25819127#post25819127

The flickering is the same as that exhibited on the Asus Transformer Prime, which uses the same nVidia Tegra 3 processor and is power management related, specifically to the Prism technology which tinkers with the backlight and colour intensity on a frame by frame basis to reduce LCD screen power consumption, read the links. I believe the US LTE version of the 1X with the S4 processor does not have this issue at all as it doesn't have the T3 CPU and no Prism technology messing with the screen.

There is also a YouTube video showing the Asus TP with the flicker like the 1X, possibly looks worse on the bigger screen of the tablet:

http://www.youtube.com/watch?v=hxyTUc2cVTw

And YES it was software related AND FIXED with a software update.

We just need to sit tight and wait for an update, possibly 1.30.xxx ota

Again, please read the thread before posting questions that are already answered, or better use the search!
[HTC One X] HaTeC:
I did read this but i am not convinced, i thought i missed something other than this.

Why doesn't it affect all one x phones if it's software?

Because the different LCD models?

Why does it get better and worse if it's software?

Let's hope for 1.30 like you say.
[HTC One X] Disket:
I have complained to HTC support last week regarding my screen issues and demanded for a replacement/refund but unfortunately the support officer was less than helpful. I almost gave up until I received a call today from HTC Taiwan.

The person said they're aware of the screen issues and will release an update to fix it this month. I double checked if it was the 1.29 update, she said it's a newer version. She also mentioned that the issue had something to do with different user apps installed on the phone. Advised me to not change the phone yet as it'll probably just happen again and asked me to wait for the update and see how it goes.

Finally a glimmer of hope and I'm happy they gave me a call. Btw, I'm from Malaysia.
[HTC One X] farnsbarns:
HTC say it's software and they're working on it day and night. I think we can only take that on face value and give them the benefit of the doubt. They are doing the right thing in that they are still accepting warranty returns for the fault so if you're truly unhappy, or believe it's hardware, return it.
[HTC One X] middlep1:
Yes, hardware variance is probably a factor, there are at least 2 different manufactures of LCD screens used in the 1X, other factors which are backed up with evidence are the battery charge level with some users reporting flickering starting at around the 65% discharge level, other saying it goes away when charging, Screen brightness setting, any stock power management settings you have changed and any third party power management tools you have installed yourself could all affect the timing and severity of the flicker/shimmer affect.

When you read up on the Asus Transformer Prime flicker issues, they are almost 100% identical in description to the 1X, some users had it others didn't, but it was a Tegra 3 device like the 1X int'l version.

I am 100% sure this will be fixed with a software update and is all down to software driver controlling the Prism technology that controls the LCD frame by frame making adjustments, it is probably just getting all confused and freaking out
[HTC One X] lawrence750:
i don't see any flickering in that video. all i see is graphics glitches.. completely different thing.

its quite obvious that those glitches would have been solved with software.
[HTC One X] Robpollard:
@middlep1

Are you sure you're talking of the flickering that occurs when the display is showing greyish colours? If the display is mixed, all colours are displayed perfectly but everything near grey is flickering a bit like a stroboscope.

My "immediate exchange" is slowly running out but I'm not really ready and eager to go through all the hassle with relocking the broken one and then unlocking the new one and setting everything up again.

I'm really unsure how to proceed, since I'll be angry as hell if I discover after exchanging the phone that a "simple" software fix would've done the trick.
[HTC One X] vinegarjoe:
Rob, that basically sums up exactly my predicament, thanks for getting to the point (unlike myself). There seems to be several issues: screen corruption/flicker and a clear refresh rate problem when the screen displays a lot of grey. It’s this last issue that really bugs me: specifically I can see the screen refreshing (at 10's of Hz) when on a grey screen.....and its very annoying (not to mention the fact that it’s probably not great if you suffer from epilepsy).

I’ve no idea whether or not to return of hold out for a software update.
[HTC One X] Harnec:
as far as I understand this is the kind of flickering we are talking about and it is also my problem. greyish colors flicker especially light grey when it covers lot of area. (my case it is only visible above %30-40 brightness level)

I heard some guy replaced 4-5 phones to find an unflickering device.

More than one guy from HTC told that this is a software problem. so I decided to wait for software solution first because there is no warranty at the moment that if I replace my 1X the new one won't flicker. This is issue seems to be very common.
[HTC One X] middlep1:
Look again at the video. The banding effect caused by the camera along with the screen flicker is there in plain sight, there are no graphic "glitches" in the video and all graphic glitches on the 1X were fixed with the 1.28.xxx ota update

YES, it manifests itself a little differently on each device and differently again on the Asus TP, it is the same issue, Tegra 3 + Prism technology + bad drivers = screen flicker, the Asus had major issues on all screen colour types, the 1X seems to be more weighted towards mid grey colours, but some people are reporting it on white screens too with a backlight pulsing/strob effect, and some unlucky people (or those with a sharp eye) can see it all of the time regardless of colour on screen.

The issues are/were the same on both devices, and the Asus was fixed, so I 100% believe the 1X will also be fixed with a new update, just have patience and wait....
[HTC One X] turbox:
HTC france support just call me. They said it's not a know issue. I must send back my 1X to be repaired (the second time) and they'll change the screen ... So desapointed.
[HTC One X] middlep1:
It is a known issue, this thread is all about multiple conversations the OP has had with Robert Collins - Customer Experience Manager for HTC Europe. And that they have identified the cause and are working on a software fix.

Sounds like you have just been brushed aside by a low level customer support rep who doesn't care about your problems, phone back and give them hellfire...
[HTC One X] joplayer:
I know HTC France very well. That is the worst customer experience available I think :p

If an update is out to solve the problem they won't even know it. The support is a separated company. It's just paid by HTC to provide prepaired answers.

So when you have a problem you are ****ed.

So you have the choice :

-You have enough money to take the risk and not make an exchange to wait for a possible OTA.

-You make an exchange to play it safe (that is what I did and am gonna receive my 3rd one x soon)

However in your case the exchange seems impossible so you are on the 2 years guarantee period.

If you like your one X except the flickering or don't want to be separated from it you can wait another month for this possible OTA I would say.

Add the fact that the repairs in France are pretty bad (was for me) and it damages the devices. So as long as it's not exchanges if I were you I would wait another month.
[HTC One X] turbox:
That's right. The only defect is the flickering and don't want my 1X is damage by travels and repair operation.

I'll wait a little and will advise later.
[HTC One X] lnoormohamed:
same here contacted HTC and they emailed me back saying its not a know issue.... but it is since you all are in the same boat..... wonder how long it will take when we see the Software update

really annoyed with them on my third one all different issues
[HTC One X] twistedh:
I almost spoke to HTC Denmark yesterday. Originally started talking to a manager, as he claimed, then fobbed me off to a low level advisor who said they weren't aware of the issue and merely told me to factory reset my device.

Absolutely useless. My previous conversations, they acknowledged the issue and told me to exchange my device or wait for an update. From my experience yesterday, it felt like they were trying to ignore it.

I love this phone, but the way HTC have f$%^ed us about, has really annoyed me. The first time I've had any issues at all with a mobile phone - of course it had to be my first HTC... great first impressions guys.

It's a shame the galaxy S3 looks like a piece of turd otherwise I'd consider a switch.
[HTC One X] PAGOT:
Ehm, as I said before.

Everyone who can notice the imperfections of the IPS/SLCD will hate the AMOLED.

To time its the worst quality built display ever(hopefully it will change in time).

So its even pointless to compare SAMSUNG's phones/screens to IPS/SLCDs

NOW Where the IPS/SLCD can be good (fixed by the hw or sw etc) the AMOLED (and even worse the non plus version = pentile) will be always bad.

AMOLED:

-colors age (in a much faster way as LCD, and if you will have your phone for a year you will notice)

-tearing effects

-short and long term memory effects, burn ins = this is a goody

-uneven backlight

-stripes across the screen

-green lines

-I think am forgetting something

and pentile - not sharp, edges not smooth, etc

How did the f-ed you ? I mean I do not think every little person in a support center will know about this issue. And its not HTCs fault they might not know about it... (I work in a SC too, and most of the time you are forbidden to acknowledge a bug, that can and will be fixed in no time, in an open manner)

They told you to get it replaced or fixed..

You could consider yourself f-ed if they would tell you. There is not problem with your phone. Its your eyes...
[HTC One X] HaTeC:
I love these people defending HTC, or any other company in cases like this...

You people really amaze me.

A premium electronic consumer device should be shipped flawless - nothing less is acceptable. Good for them there are people like you with low standards.
[HTC One X] twistedh:
The fact is this. We all spent a lot of money on a supposedly premium handset. It was shipped out with issues which MANY people have, if you would look around on the forum with all the complaints.

It is HTCs fault as depending on the day, time, who you talk to at HTC, they all provide different excuses/promises. A simple acknowledgement of error on their behalf would go a long way.

The fact that the phone was riddled with some problems on release made big news in Taiwan.

We shouldn't have to keep replacing our handset as we have been advised. Some people on the forum are already on their EIGHTH handset after getting different degrees of the screen flicker and other problems. Understand this? Having to exchange your phone, 8 times? And many others at least 2 or 3 times in order to get a fully functional handset.

You shouldn't have to wish for a fully working phone when you go to buy it. You expect it.

---------- Post added at 09:14 AM ---------- Previous post was at 09:05 AM ----------

This is why there are 2 threads on this particular topic, filled with people complaining about the issue - most contacting HTC regularly to see what the situation is. If they don't know about, they should.

Even yourself, state that they should have a note of the issue. We've been complaining to them for a month now, I'm sure they are aware of it. They've even stated in a couple of conversations that it is a software problem and working on a fix. But to others, they just say to change the handset.

Let's just hope they have a fix prepared to release in the next few days as the rumors suggest.
[HTC One X] HaTeC:
I knew it's a matter of time untill the whole software industry's "ship it now, fix it later" attitude would stick on to other branches.

It's all bull**** in my opinion.

What's next? shipping cars with faulty brakes?

It's the consumers fault, no one else. People that accept substandard quality and have no problems accepting all this **** are the ones to blame.
[HTC One X] Trev16v:
In the various threads on this topic (which are specifically talking about the grey / white flickering, or apparent backlight strobing), I see various people insist that there is no problem. For instance, I read one poster claim to have gone into a store and checked all phones and saw that they were all fine.

This is in the face of the fact that many people are on their umpteenth phone to find one that doesn't exhibit the problem. It's also unconvincing for me personally, as all HOXs I've seen that colleagues own behave exactly as mine does; i.e. flicker on mainly whites at minimum brightness.

None of my HOX-owning colleagues could see the issue when I pointed it out under low ambient light. Therefore some people just won't be aware of it, while it bugs the hell out of others. And, being in a phone store where it's probably all brightly lit (perhaps with some flourescent tubes above you) is not a good way to test for it.
