[HTC One X] :
+1

Also, I have that banding issue, which kinda sucks. By taking a screenshot and transferring it to my iPod, I'm sure the gradient itself is perfectly fine and it's the device messing it up. The brighter the screen, the better you can notice.

I checked the One S at our local hardware retailer today and there is absolutely no banding. Looks gorgeous (even though I hate PenTile). They also had another One X which has exactly the same issues... I hope it's a software issue and that 1.28 will fix it. I tried several gradients and I can tell the ICS gradient looks worst. A CSS3 gradient shows similar issues though.

Off to get a USB->HDMI adapter in order to tell whether it's the screen or the GPU :\

EDIT: banding is even worse when rendering in FF? Software issue?

just saw another One X, the banding wasn't as bad. Hardware issue?

no shop had the adapter in stock, so I'm going to order at amazon
[HTC One X] wizard123:
I have an hdmi adapter I will test in a minute and let you guys know the outcome
[HTC One X] d33f:
Thanks for checking it out :)

I do hope it's a software/driver issue, because the display should be capable of displaying gradients without banding
[HTC One X] wizard123:
Well I can tell you there is no flicker what so ever on external hdmi so its either a driver issue or faulty backlights
[HTC One X] :
Could you possibly check the banding thing, too? The Google+ app uses the standard ICS gradient for example. If there is no problem on the screen, I guess all of our devices' screens might be screwed :(

P.S. I will share some camera shots of the banding issue soon.
[HTC One X] wizard123:
Which banding issue do u mean ? So many people discribing them in different ways
[HTC One X] d33f:
There is only one color banding ;) the problem is people using the term improperly.

Color banding is when you can see clearly the transition in color in a gradient.

like on this image:

As you can see on the keys the gradient is not evenly spread color-wise, and you can see the transition clearly from dark to light (this is called color banding).

Furthermore i tried running LCD tester on my gf's Sensation XL. It does show the same color banding :(

Could it be a common S-LCD issue ? because Sensation XL uses a S-LCD(version1) screen too
[HTC One X] wizard123:
I'll be honest with you i cant see that issue anywhere on my device, no banding anywhere just the flicker fault on mine. :confused:

Hi moshinraza i am frm india...have same number dt know abt rest
[HTC One X] predator21:
Hi d33f in lcd test grey n light colours produce little flicker. We mst wait this issue can't b ignored by htc.
[HTC One X] :
I mean the only banding that should be called this way. Look at the ICS gradient on your device (Google+ app, e.g.) set the device to maximum brightness. If the gradient is perfectly smooth, you have no banding. If it seems a bit "tiled" and you can clearly see transitions, you have banding. All the three One X devices I've used so far had this. When I take a screenshot and transfer it to another device, there is no banding. Which means it's either the rendering or the screen causing this. If it's the rendering the issue should be visible on the TV, too. If it's the screen the image on the TV will be fine and we're screwed. In this case if we're reeeaaaally lucky, there's in issue in the background led driver, which can be fixed. Else we will need to contact HTC to get new devices/screens.

I'm really looking forward to 1.28 which is supposed to fix some display issues. Let's see if this one gets fixed. I hope so :)

Also, thank you so much for your efforts.

You've 1.28 and it's having no problems?

[HTC One X] mohsinraza:
I've many found almost 5-7 people who have 1.28.xx firmware number and they don't have any problems.

I think fresh arrivals in market is now free of problems and running 1.28.

Found no one who said 1.26 is running fine.

[HTC One X] nikzDHD:
Anyone else have 2 lines near the middle they are visible when on a lighter grey background. Titl your phone to the side and look in the middle on mine I can see 2 lines running down the screen. Very hard to capture on a camera. Get lcd test from the market and put it on the grey background.
[HTC One X] :
Not for me... Luckily :P

No really, I don't have any flickering or whatsoever as long as I'm not on minimum brightness, which isn't really a problem, because I don't use my phone too often when it's that dark.

---------- Post added at 07:26 PM ---------- Previous post was at 07:21 PM ----------

I don't have that issue, I think that really is caused by bad hardware, you should try to return it IMO. What I have is when tilting your phone left and downwards I can see some kind of pattern:

001

010

100

I think this is normal, caused by coating and I don't really give a f***.

As for 1.28, I'm still waiting ;)
[HTC One X] nickporwal:
I bought my ONE X 5 days ago. I must say i didnt had any flickering first 3 days but dont know what happened, my screen has started to flicker. I can see the flickering mostly on grey background. I wonder if this flickering is related to some settings or app installed. I just hope this is the software issue and not hardware.

Really this is pathetic of HTC that the flagship device has so many problems. If HTC really cares about its customers then it should release the fix ASAP.
[HTC One X] ajeya:
Got my phone yesterday but i am not facing such issues. its on 1.26.720.2

Any other way to test? i tried those grey backgrounds.

EDIT : Tried a grey wallpaper in a dark room for some time and i started noticing a slight flickering. Weird...lets see after 2-3 days.
[HTC One X] nikzDHD:
I think it might be that seems like some patterns. Mine is going back next week got my pre paid envelope yesterday so back in the post it'll go.

Before I send it back might just unlock the bootloader and quickly flash pauls 1.2.8 repack and see if that solves it. One thing I've also noticed is that the screen sort of gets stuck when I'm using my keyboard on the left side its don't register my touch at times the screen feels rough compared to the right side.
[HTC One X] mertzi:
besides the flickering on low brightness I have that banding. So what you're saying is that this can be hardware related too?
[HTC One X] 131313:
Change the settings

Because there are probably quite many people following this thread, I want you to know of this issue in ICS 4.03. See my post http://xdaforums.com/show....php?t=1599214

its not even related to flicker lol :)
[HTC One X] mertzi:
when I'm in a room with no windows and no lights and have auto brightness the screen doesn't go nearly as dark as when setting manually on lowest brightness. Maybe the screen isn't supposed to go as dark as it can right now? Cause to me it doesn't flicker with auto brightness but auto in a dark room is like 15-20% non auto.

Can't wait next OTA.

So bad there is no communication at all on this issue from HTC...

Is there at least one person that doesn't have this flickering ?
[HTC One X] msmit4:
Flickering

I had lots of flickering with my One X too. Contacted HTC and they advised me to return to the seller and exchange it for a new one.

I swapped it yesterday and this makes a world of difference. No flickering at all.
[HTC One X] joplayer:
Now I have no idea whether I should switch it or wait the OTA.... And won't have a phone for a week if I switch...
[HTC One X] AFX21:
I also noticed some minor flickering but not annoying.
[HTC One X] Havoc2k:
the flickering is not that big deal for me. worste is the "blinking" of my screen sometimes. the background light is blinking very fast.

my phone will be replaced next week, lets wait if the other handels better.

i wonder when HTC and the resellers will run out of phones...
[HTC One X] :
Newest rumours say, the OTA will get rolled out tomorrow. I'd wait another day, see if anything gets better and if not, send it back. There's nothing worse than having to look at a certain issue day after day without being able to fix it :(

EDIT: the captcha for posting is finally gone :)
[HTC One X] joplayer:
Thanks for the info !

Hope you are right !

I'll indeed send it back if the OTA does not solve the issue...
[HTC One X] nikzDHD:
It's not fixed in the Chinese version, so not sure if the European version will be fixed as well. Better to be safe than sorry and exchange whilst you have the opportunity to do so until you get a flicker free device. I'm talking about the jumping strobing effect on grey backgrounds.
[HTC One X] mohsinraza:
Can you please tell me the firmware number of your device.

[HTC One X] d33f:
It could be, but i don't know for sure. Most of the times this issue is software related.
[HTC One X] nikzDHD:
I think a video will define the problems we are having.

Look at this video:

[YOUTUBE]6T69rrkXIDg[/YOUTUBE]

I have a similar effect of white levels strobing like that on grey backgrounds. On all brightness levels. As well as banding on various applications.

This video shows it a bit better, look at the TV the white strobes at the beginning.

[YOUTUBE]PW-DWnsKjbg[/YOUTUBE]

Exactly that kind of issue on my HOX noticeable when viewing battery stats and on grey backgrounds and some light backgrounds.
[HTC One X] wizard123:
Yes this is the exact issue i am seeing too, although if i disable the gesture option and fastboot in setting then reboot i no longer have graphical glitches or wave artifacts in youtube etc.
[HTC One X] nikzDHD:
I've done that but no luck, I think mine wasn't bad at the beginning but has got worse at first didn't have, then started appearing on low brightness levels now noticeable on all brightness levels!

The YouTube glitch is gone.
[HTC One X] mrcgibb:
My one x is the same , but the whole screen is now flickering on every colour etc , i am fortune enough to have 2 i ordered one from chitter chatter and one from dial a phone . i cancelled the dial a phone order but the phone still arrived , i am sending it back soon .

unfortunalty the tmobile chitter chatter contract one i am keeping has very bad flicker now ;( the dial a phone one is perfect , but the whole screen looks better .

Its not just the lack of flicker , place both phones on auto brightness and the dial a phone one is simply far better to look at colours are brighter as well !

both phones are network unlocked , i did think about sending the chitter chatter one back as the dial a phone one and keeping the dial a phone one as mine but i am sure they will notice the change of serial ? ;( gutted as i have a great one here and a crap one i have to keep
[HTC One X] nikzDHD:
Yes IMEI's would have been recorded and such. DOA the Chitter Chatter one and get a replacement you are still within 28 days so won't hurt.
[HTC One X] mrcgibb:
problem is i have rooted this one ;(
[HTC One X] nikzDHD:
Should be fine, I've rooted mine but going to send it back and see what happens. Revert back to stock by flashing stock firmware. We've used the official method to unlock so should be fine.
[HTC One X] mrcgibb:
silly question but i have tried to find a guide to flash back stock so i can return , but cant find one ? i made a back up before installing new rom , is it just a case of restoring it ?

---------- Post added at 02:05 PM ---------- Previous post was at 02:00 PM ----------

hmmm strange thing about this flickering issues are when installing a new rom such as leedroid`s on the install menu the screen looks great , no flicker or anything , but when ics starts up it returns , so maybe it is a software issue?
[HTC One X] nikzDHD:
Flash back your backup, then flash stock recovery.

We don't know if it is a software issue or hardware just speculation. Nor have HTC said anything bar to return handset for a replacement!
[HTC One X] znanev:
Guys just a quick update on these issues. Just returned from Carphone Warehouse with a brand new HTC One X replacement. I returned the phone mainly because of the banding issue. Guess what was my surprise when I saw this appearing on the new device when I just stepped out of the store. The assistant said she will issue me a refund if I wanted so, but I really like the phone so I decided to keep the new one for another week. But I really can't understand HTC's policy - they advise everyone to replace their phones, but obviously this is pointless. So what I intend to do is to wait for an update and if one does not come out soon I will have to get my money back and wait for a better batch eventually.

This is an interesting post https://discussions.apple.com/thread/1057743?start=0&tstart=0

Now i know we cant change these settings without access to the kernel but they seem to have the same flicker issue on grey/blue matte images and they fixed it by taking the refresh rate from 60hz to 70hz.

Edit* I also forgot to note that our displays only have a refresh of 58hz
[HTC One X] gempitax:
reply from HTC

Thank you for contacting HTC!

Regarding your HTC One X issue, we will forward this to our Technician Department for future improvement.

Meanwhile, please try below steps to set your phone under safe mode to monitor it:

First verify that Fast Boot is not enabled, select All Apps > Settings > Applications or Power > Make sure Fast Boot is not selected. To enable safe mode:

1. With the device turned off.

2. Press the power button.

3. Once the device turns press and holds the volume down, once you see the splash screen.

4. Press and hold thevolume down button (DO NOT RELEASE THE VOLUME DOWN).

You will know it has worked because the device will give a brief vibrate or 3 quick vibes. Once it loads you will see on the “Safe Mode” on the bottom left of the screen. This disables all 3rd party apps and drivers from launching. Use the phone normally for 24-48 hours like this. Do not use 3rd party apps or install from the market or the test will be inconclusive.

If the issue will not occur under safe mode, please uninstall the 3rd applications.
[HTC One X] wizard123:
I have done this and still the flicker persists !

---------- Post added at 04:09 PM ---------- Previous post was at 03:58 PM ----------

Here you go guys number 2a in this test is the flickering exactly

http://www.lagom.nl/lcd-test/inversion.php#invpattern

(do NOT run this test if you suffer from epilepsy, and I'm not joking)

"If you instead see flickering in images that don't have dithering encoded into them, then you may be seeing an interaction between the dithering pattern being used by your video card and the interleaving pattern of the monitor. If such flickering becomes too objectionable, then you may have a dithering setting somewhere in your nvidia control panel (or a setting in the device manager for your video card, or in a .conf/.ini file) that lets you change the display card's dithering pattern, hence reducing the flicker."

Funny that that quote mentions nvidia as the display card too.
[HTC One X] joplayer:
This test nearly killed me in front of my desktop computer :P

What is it actually ? static pictures ?

And if we see flickers that mean there is some bad driver/screen on our side ?

In this case my computer which doesn't flicker in real like is much worst than the One X...
[HTC One X] wizard123:
Strong flicker indicates that the voltages in the monitor are misadjusted. Unfortunately, this is probably not something you can adjust by yourself. In practical situations, a visible flicker here means that plain colors show "pixel walk" when watched from close-by.

An ideal monitor does not flicker and does not show this ghosting either.

In a pixel on an LCD monitor, the amount of light that is transmitted from the backlight depends on the voltage applied to the pixel. For the amount of light, it doesn't matter whether that voltage is negative or positive. However, applying the same voltage for a long period would damage the pixel. Do you remember how electricity decomposes water into oxygen and hydrogen gas in chemistry class? Similar things could happen inside the liquid crystals that are in the pixels. In order to prevent damage, LCD displays quickly alternate the voltage between positive and negative for each pixel, which is called 'polarity inversion'. Ideally, the rapid polarity inversion wouldn't be noticeable because every pixel has the same brightness whether it a positive or a negative voltage is applied. However, in practice, there is a small difference, which means that every pixel flickers at about 30 hertz. In order to make this less noticeable, pixels with positive and negative voltages are interleaved, such that on average the screen as a whole keeps the same brightness – at least for normal images. The interleaving does not work for the inversion test images, at least for the one(s) where the pattern matches the interleaving pattern of the monitor. In such cases, the monitor will flicker if the positive and negative voltages are not tuned very well. Note that the patterns 2, 4, 6, and 7 are split into an 'a' and a 'b' version. The only difference between the 'a' and 'b' versions is that they are offset vertically (2,4,6) or horizontally (7) by one pixel; which one actually flickers is dependent on how you position your browser window.

Nice piece of info.. Now I'd like to know how far HTC can change current values in there Radios because that is most likely not manageable by the kernel. Except as done on the macbook by forcing refresh rate to a higher frequency. But that is the screen configuration that really needs some modifications and that is as far as I know only doable in Radios.

That leads us to the same conclusion : We need next OTA. And I'm starting to doubt it being 1.28 because as reported the chinese version of it still had a failed nvidia power management implementation. I think we will more have 1.27 or something higher. If we got 1.28 they better have to have fixed these issues from china version...
[HTC One X] wizard123:
Agreed totally i think 1.28 is just blowing smoke up our as*es, it would not suprise me if there is not even an update anywhere near ready for release for these bugs. It does give me the feeling tho that this will be a software fix and not the hardware that is faulty.
[HTC One X] joplayer:
If they don't have anything ready then it would be stupid from them to stop their previous 1.27 OTA that was released for reviewers. They must have something ready pretty soon... And it has to include improvements since 1.27 to justify the blocking of its release.

I really hope we can solve our flickering with this... Don't wanna send it back ;(
[HTC One X] wizard123:
Your making the mistake of thinking they actually care about customer service lol, all they care about is selling phones and the longer they keep their mouth shut the longer it takes for the masses out there to know about the issues and therefore they keeping selling phones and call it a hugely successful launch.

Screen issue

Well I am not facing some big flickering issue but yes my screen's resolution has some issues I guess. at the bottom of the screen the screen starts getting shorter and bigger at the same time. Its very annoying. This is happening is all applications. It shrinks then it fits back and this keeps on happening for 10-15 mins.

I don't own ONE X yet because I'm to appear in my exams in 15 days. I'll be getting one after exams.

But the fact is I've talked to people who've 1.28 and their device is fine.

The bugs are the mixture of hardware and software issues. Flickering is, what I think, a hardware one.

Is 1.28 out in other areas or not - I'll be shortly back on this.
