Deffol let us know
[HTC One X] DazNoonan:
Well I ended up going in a meeting so couldn't call them. Been sat here for the last 15/20 mins though sending/receiving texts along with taking a pic and putting it on Instagram and i've seen no flicker at all. It really does annoy me when this happens as it makes me doubt the whole flicker nonsense, and again makes me point the problem towards software rather than hardware.

Oh wait text has come in and the flicker is back... and its likely to stay for a while as its been there most of the day since the battery came of 100%.

What am I going to do... I honestly don't know 50% of me says to call Vodafone and exchange it and 50% of me says live with it and hope an OTA fixes it and that it doesnt get worse over time.
[HTC One X] mwilky:
Exactly the same for me, this is the first one ive replaced, but i can't afford to be without a phone for a week, i rely on my phone heavily for work and if this first replacement doesnt solve it, if its come from the newest batch aswell, i'm just gonna convince myself its software
[HTC One X] DazNoonan:
I was wrong it actually only game for a couple of mins and has gone again... Very strange as not had it do this before.

---------- Post added at 05:44 PM ---------- Previous post was at 05:42 PM ----------

That's kind of what I am thinking... I definitely can't be without the phone if it had to go away for repair, and to be honest I can't keep doing this 7 day exchange as its killing me and I keep having to ensure I'm around to make the exchange which is sometimes easier said than done.

I convinced myself it was software from day 1, what I need to convince myself of now though is that I believe they will fix it.
[HTC One X] mwilky:
The thing thats annoying though is ive gone to HTC online chat myself, under different names, my mates have done the same and we all asked if it is known issue and every time HTC have replied saying "no we havent heard of this one before." I dont see why they just can't admit that they have a problem, does anyone know if this bug was present on the demo devices?
[HTC One X] oxfordmark:
I went on it once and she was aware,said they are looking into it
[HTC One X] BarryH_GEG:
For those that flicker, here's something to try. My phone doesn't flicker so I'm assuming that both its h/w and s/w are within spec. Those that flicker are obviously out of spec in some form. Below is my AnTuTu test score. In the second shot, another One X got a very different score. I'm trying to see if there's some correlation between CPU/GPU performance and the flickering. I don't know if the other One X flickers or not, I clipped a still from a comparison video. Regardless, a 20% performance deviation between two supposedly identical phones is odd. And the 2D graphics score on the other phone is 45% worse than mine. If someone who flickers get performance similar to mine than it's probably not h/w. If none do, it points to a Teg3 h/w anomaly.
[HTC One X] optiknerv:
UPDATE No. 1 Updated to 1.28.xxx as soon as the battery got above 35% charge and the device is still flicker free after doing so.
[HTC One X] oxfordmark:
10653 was my need bench mark
[HTC One X] oxfordmark:
Maybe this software update did improve it after all.
[HTC One X] BarryH_GEG:
What were your 2D and 3D graphics scores and does your phone flicker?
[HTC One X] wietse1988:
HTC one x

@ antutu benchmark i have a score of 11651, and i have the screen flickering..
[HTC One X] optiknerv:
As i previously stated there was no flicker before the update. It is a brand new device only turned on for the first time about an hour or so ago. I updated to 1.28.xxx as soon as the battery was over 35% (the minimum required for update) and after doing so it did not cause it to flicker. Some people had previously stated that after the update their flicker free devices had started to flicker!!
[HTC One X] oxfordmark:

Interesting , low battery, and mine says CPU frequency is 1000mhz?

[HTC One X] Ipy219:
i have screen problems only when the colours are grey.i tried several lcd test from market and all did the same.red blue white green yellow screens no problem..but grey screen..it starts flickering like an old tube monitor from 10 years ago.the problem is that all f****** sense is grey :)) so i have this problem everywhere.ohh and a pixel died in the right corner.after 2 days of using a brand new 600$ phone.

sry for my bad english
[HTC One X] oxfordmark:
What was the box like that it come in? Mine was a tiny thing, the phone had "the one your waiting for"or similar
[HTC One X] joplayer:
Just received my exchange device :)

Now charging, will tell you if it flickers. Of course I know the problem comes with some times too but my first device had it since day one so...

Don't know why but build quality sounds better on this one... Howevever I don't have much expectations considering it has an even lower Serial number than the previous one (6000 before)
[HTC One X] DazNoonan:
I got 10903 with a 2D score of 147 & 3D score of 1239. that's on a flickering device. Not sure what tells you?
[HTC One X] BarryH_GEG:
I'm looking for signs of h/w deviation between flickering and non-flickering phones.

The 3D scores seems reasonably close but the 2D scores are all over the place:

Mine: 286

Vid Cap: 158

Oxfordmark: 285 (flickering?)

Yours: 147

You can test the various components seperately in AnTuTu and I ran the 2D test seperately three times and got the same score each time. The 2D performance difference between your phone and mine is close to 50%. Identical phones produced within weeks of each other using the same s/w shouldn't have that big a deviation. Oxfordmark didn't say whether his phone flickered or not.
[HTC One X] studentu05:
antutu

2D -283..

3D -1164

Total score 10307

Got flickering for 30 minutes one day and that was it.Now looks ok.No flickering
[HTC One X] oxfordmark:
Yes flickering
[HTC One X] BarryH_GEG:
Hmm. I posted in the dev section asking the devs to try and explain the huge deviations in the 2D graphics scores between devices. It's not happening on the XL, they all perform reasonably close. With your answer, it's starting to rule out h/w and points more to drivers or low-level code. The devs know a hell of a lot more about this stuff than I do so I'm interested in their responses.
[HTC One X] oxfordmark:
Post there thoughts here please
[HTC One X] Shikakka:

Thing is,if it is a software issue, those with unbranded phones will be waiting hell of a lot longer for this fix.especially on T-Mobile.

Flickering ?
[HTC One X] Techimplant:
Guys on certain apps like mx player the ads at the bottom of the screen flickers n go away n come back again after few seconds n again flicker n go away...no other problem with Grey's n all..just with ads..can this be classified as flickering?

Sent from my Stunning White HTC One X
[HTC One X] lawrence750:
I have noticed flickering, when the ads popup etc, except its the whole screen.

This may just be a red herring though. As it does sometimes seem like CPU usage cause the screen to flicker, the ads loading would cause a spike in CPU usage.
[HTC One X] Ripley:
Non flickering Taiwan ht24
[HTC One X] Techimplant:
So what shall I do?..go for a replacement?..but everything is fine except this..

Sent from my Stunning White HTC One X
[HTC One X] oxfordmark:
I'm going to exchange tomorrow
[HTC One X] RomNoR:
I was just at the store and looked at a ONE X that is on 24/7 and played with all day...

no flickering.

Funny huh?

it was a HT23FW GRAY

Mine is a HT23KW White and it started flickering after 10 days.

I asked the guy at the store how many flicker complaints he got, he said none.

He also said he asked colleagues in other stores and they said none.

When i showed him my phone he didn't see the problem...

so....

Either way, let's wait for that official response on this fiasko.

---------- Post added at 10:33 PM ---------- Previous post was at 10:31 PM ----------

Mine started flicker when i updated.

Maybe a coincidence maybe it's not.

I am so sick of this i am willing to wipe my device and downgrade it back to 1.26 to just check.

Anyone want to instruct me how to downgrade without rooting?
[HTC One X] BarryH_GEG:
That's the lowest 2D score yet and you have no flickering yet the highest score does. That pretty much rules out h/w alone. There's something wrong with the graphics drivers for the phones to be peforming so differently. 2D particularly seems to draw it out. Voltage and frequency were discussed and that could vary by chip (even though it shouldn't) but if it's not directly impacting performance than it's tuning the s/w to better work with the h/w rather than outright h/w failures. I guess the good news is that s/w is a lot easier to fix than h/w.

As for the imbedded ad banners flickering, I have a non-flickering phone and the ads do flicker when they appear. It doesn't affect anything else on the display and it's fine when I close the app.
[HTC One X] Shikakka:
Mine started flickering after the update to. Before that it never occurred. I asked some friends and parents but they didnt see the flickering. Even though I could clearly see it in de grey background.

Also I noticed at all the stores the flickering.

WTF? AnTuTu tester reports a CPU frequency of 1993.93
[HTC One X] BarryH_GEG:
You guys have gone in circles for 50+ pages. Here's a recap:

1) HT23 and HT24 phones come with and w/o the flicker

2) There are Chinese built phones that flicker

3) There are phones that flicker out of the box

4) There are phones that flicker after a few days use

5) There are phones that flicker cold

6) There are phones that flicker when they're hot

7) There are phones that flicker on certain apps and not others

8) The flicker doesn't appear uniformly across flickering phones

9) The way an individual phone flickers can change from day to day and app to app

10) No one's reported the flickering going away once it's appeared

Taking that all in to account, what do you truly hope to gain buy repeatedly posting "my H23 flickers" or my "H24 doesn't?" And since it’s likely a s/w problem, unless the HT25’s have a different ROM, they’ll act just like the HT23’s and HT24’s before them. I've followed this thread from the beginning and it's a completely random problem; the most difficult to isolate and resolve even for engineers. Until HTC releases a fix, items 1-10 above are going to continue to randomly repeat themselves. By all means post if it's cathartic, but we're not going to be able to identify or resolve the problem ourselves. Even the devs can't because if it's related to Nvidia code or drivers they have no access to make any modifications.

If you don't want to deal with the hassle instead of exchanging your phone return it and re-buy it once the problem's fixed. In another thread someone heard from HTC an update's due by the end of the month that's supposed to address this.

Peace out. :)

---------- Post added at 02:13 PM ---------- Previous post was at 02:05 PM ----------

That's odd. Chips can be out of spec but they're usually low not high. In AnTuTu, go in to test, hit custom, and only select CPU and Memory. See what the stat is when run alone. You could have one of the fastest One X's built. ;)
[HTC One X] M1stral:
I had a flickering device:

2D: 291

[HTC One X] hamdir:
in case you guys missed my new declared war post on HTC

i always wondered what this flickering is all about, since i bought 6 so far non with flickering and some with issues like flexing

so today i encountered finally in a perfectly fit and finished unit, no flex no rattle no nothing, i broke the seal myself

the screen was blinking clearly in all brightness level, most obvious at low brightness in the snow and sun image, the screen was also rippling badly when the far right corner is touched

this is clearly an issue with an imperfect yielded Tegra3 unable to full-fill is target clocks or being another manifestation of the repeating screen lamination problems

i doubt it has anything to do with voltage regulators

:mad:
[HTC One X] BarryH_GEG:
This is exactly what happened on the Prime. The s/w was designed to expect responses within a certain range and the h/w was performing outside that range. Nvidia changed the drivers and/or low-level code to compensate. It wasn't pretty and took three updates to get it right.

Speaking of strange behaviour. What's your take on why there's such a big deviation (close to 50%) on the AnTuTu 2D test between One X's?
[HTC One X] oxfordmark:
This is my worry, the only issue I have is the flickering. What if I replace it and it has more than that.

Do the other issues (bad screen fit, yellow dots) appear as soon as the phones first used?
[HTC One X] Sathom:
Anyone knows what this is? I have 10 equally spaced dots on the bottom part of my screen. Is it the backlight or?
[HTC One X] ste1164:
Part of the backlight for the LCD I think.
[HTC One X] Sathom:
Is it normal or a manufacturing fault?
[HTC One X] hamdir:
display tester is the best app to figure out if u have it and if its hardware

no flicker here
[HTC One X] ONE981:
Hey there, my phone had the terrible screen flicker and mad green distortion down the side when I tried youtube.

Also, first day I remember getting some funky swirl type crap when the screen was white and scrolling.. Happy to say all gone, nothing like that. After maybe 3 days and a reset phone is bugless for now. Very happy finally. Battery is actually really good too now. I firstly belive it could/ could have been software. Otherwise, it could even be something simple like glue drying out around certain parts of the phone, manufacturing being so soon.. I remember the SGS2 had something like this and after a while the screen glue faded away and the screen looked normal. Different thing but its a shot if a bit long.

---------- Post added at 07:54 AM ---------- Previous post was at 07:51 AM ----------

China or Taiwan?
[HTC One X] hamdir:
thanks for the SGS2 info im definitely into the glue theory, phone is getting better by the hour :D self healing HOX :D

view angles are a bliss and an actual usability feature i can finally use an android laid on the table no matter how and the touch 10 finger capture is top notch but i dont think we have NV directTouch implemented since i see some touch delay in screen tester app

[HTC One X] joshnichols189:
On the Galaxy Nexus a while back when Franco was experimenting with nightly kernels a lot one of them had a problem where out of the blue the screen would look like it was smashed and would show black and white almost like TV static but not quite. Is this what people are seeing?
[HTC One X] oawalker:
My screen is slightly flickering looks like the back light or something do you think it's worth getting a replacement or just waiting for an update ??
[HTC One X] Frozen-GPU:
Get yourself a replacement device... I am waiting for my third one x for a week now, hope it arrives soon...
[HTC One X] DazNoonan:
I would personally say wait as no doubt your next device will do the same. At this rate you will be changing the phone every few days if you want to keep trying a different one.

I am yet to speak to anyone who has not had this issue.
[HTC One X] nikzDHD:
I've just popped mine back into the post today for a replacement. I'd say send it for a replacement while you have a chance who knows when the OTA will come worse thing would be for 28 days to pass then you'll have to send it to HTC for repair which could take longer if the OTA does not fix this! Could be a lose cable for all we know in production or just faulty screens or at best an OTA can resolve this.

But judging by past phones for example my sisters SGS2 she has apparent screen issues and no firmware upgrade can solve this clearly a HW issue as many other SGS2 users had the issue as well. Different screen tech but HW issue none the less on that phone.

I'm not trying to scare anyone off, just make use of the return procedure whilst you still can as there are users who don't have this problem.
[HTC One X] hamdir:
instead of replacing your phone on box open, i advice to use it for a while and judge

certain things seems to get better with use, something with the glue or plastic, i don't know

other devices had similar experiences like the SGS2 and iPhone4 on launch

I also think if screen flicker stays after a week, it might be hardware, since we don't have it on our devices
[HTC One X] nikzDHD:
Good advice, use and see what happens. But Hamdir in my case my phone was fine when new on day 1, couple of days after strobing started appearing only on low brightness levels, few days after it was occurring on all brightness levels. Camera/YouTube glitch only occurred once after I disabled animations.

It's not apparent at first in my case but gradually got worse after a few days.

So test your devices for a few days use it normally and watch out for any issues.
[HTC One X] hamdir:
ok then ill stop celebrating until i pass few days, now im a bit worried :rolleyes:
[HTC One X] nikzDHD:
Don't be, if you can manage at lest 7 days without any issues then you'll be fine :D I still think it's HW rather than software though just my 2 cents. I've got a grey one coming today will test that one and will also test my white replacement later this week.
[HTC One X] oawalker:
I had mine since the launch on the 5th and I didn't notice the flicker at first but now I notice it all the time it also happens when I touch the screen like scrolling, it's becoming very noticeable and annoying I think I am just going get it replaced today or tomorrow and see if it makes any difference, I will check the phone before i leave the store.
[HTC One X] jonstatt:
I think the flicker is hardware related, but it doesn't mean its impossible to fix in a firmware update. I believe its to do with the voltage regulation of the backlight. As this is partially controlled by firmware, it is possible something can be done. On the other hand, it may be a bad batch of regulators. It is very hard for people to know whether to swap their unit or not. It would be helpful if the new update came out quickly to we can see. My latest unit does not do it, but I have had a previous one that did. They are not all the same....
[HTC One X] lawrence750:
well, just so you all know, because htc can't be arsed to confirm whether this is hardware or software, im not risking it - and as my 7 days cooling off period ends tomorrow, i've now arranged to have it swapped for a new one x

I didn't notice this flickering until 4-5 days after I had the device, so will have to wait another 4-5 days at least after new device to confirm whether it has happened again or not..
[HTC One X] DazNoonan:
I think you have 28 days to get it swapped don't you rather than 7? Anyways let us know how you get on. I've had this second device since Thursday and that is flickering but I am reluctant to keep changing the handset as I need to be at home for this exchange to take place. Don't get me wrong I'm happy to be at home if its 100% that the next phone will be perfect but nobody knows if its hardware or software at all so we are all just clutching straws.

I will give Vodafone a ring later and explain what is happening and see what they say about it, no doubt they will just tell me they will swap it out but again I could just keep doing this right up until the OTA if its not hardware related. Both my phones have had issues now (the first was worse).
[HTC One X] BarryH_GEG:
First response. Maps to what some of the other issues are beyond just the flickering too.
[HTC One X] oxfordmark:
Huh
[HTC One X] hamdir:
yes i can definitly tell you these are all out of box expeirences, never had yellow spots but many forums members confirmed to me that they go away, i encountered yellowness and uneveness to the whole screen that went away in a week

anyway right now the HOX is a piece of ......
[HTC One X] oxfordmark:
So best thing is to turn it on in the store and check for the yellows spots and feel the screen?
[HTC One X] hamdir:
most important check the brightness flicker, its the most worrying, since its not in all One X
[HTC One X] oxfordmark:
What do you mean
[HTC One X] DanteGR:
Non-flickering ht23, Taiwan made if it helps any..
[HTC One X] oxfordmark:
Yeah I'll be turning the brightness up to max, is noticeable on the slider screen
[HTC One X] hamdir:
most noticeable on a reduced brightness with a white background such the snow and sun image in the gallery

as for me i give up i won't touch another HTC One X box, i am traumatized
[HTC One X] BarryH_GEG:
That's pretty extreme. All new devices have s/w issues but unfortunately the One X's affect the most visible and prominent part of the device - its display. Personally, I'm convinced now that it's a combination of Teg3 uniformity and the graphics drivers. Not to defend HTC, they should have caught this through broader testing, but they are victims too. They purchased chips from Nvidia that came with drivers and other necessary low-level code and expected them to work to a consistent standard and they don't. Since the Qualcomm-based S4 isn't having any of these issues that's most likely where the problem lies.

The Prime had the same issues and they were eventually resolved by Nvidia. In a couple of weeks this will all blow over and hopefully the One X has a long and successful run.

---------- Post added at 03:13 PM ---------- Previous post was at 03:12 PM ----------

The funky behaviour of the notification bar and strange lines and borders showing up in the camera app.
[HTC One X] hamdir:
and how about the screen lamination imperfections? has nothing to do with software or Nv
[HTC One X] BarryH_GEG:
I don't count those. All the phones and tablets I've gotten immediately as they're released have had QC issues to some degree. If it's still happening on phones next month than I'd say it's a design or manufacturing issue vs. QC. It doesn't seem to be affecting a high percentage of phones even now based on the polls (I know, even one is too many ;)).
[HTC One X] DazNoonan:
I powered off the phone and back on and then ran it again and my 2D score was much closer to yours that time. strange.
[HTC One X] hamdir:
if only it was one mate, i so far tried and touched at least 5 defected devices in a row

consider this, you have a list of common defects, around 8 items now what are the chances of ending up with at least one or two of these problems...the chances are higher than you think

- screen looseness

- screen ripple

- screen flicker

- dead pixel

- yellow spots

- imperfections to the finish

- defects in sensors

- extra over heating

im pissed because the last one i tried today was perfect in every way, except horrible screen flicker plus ripple

the fact that we are discussing "specimens" is lab talk not a commercially viable product
[HTC One X] DazNoonan:
Just ran it again and got 293 for 2D and 1241 for 3D, Overall 10506. that's without a reboot and just simply running a test after using the phone a while.
[HTC One X] oxfordmark:
Just a note mines a ht23 13554 are the last few... Is that a new or older model
[HTC One X] hamdir:
