[HTC One X] ahmadcentral:
I'm on my third One X and have the same problem here as everyone else. Screen flickering on low brightness whenever the cpu is in use and or the screen is being touched.

Does anyone know when this supposed fix is coming out. It's already been a month and a half and this issue is on pretty much every phone.

What i don't understand is that my friends phone is much worse. you can see the flickering lines on the screen all the time. It's like a really low refresh rate or something. It's so bad you can see it by holding it quite far back. is this faulty? because mine is not this bad.
[HTC One X] Cloudane:
I'm not sure if I've had the general flickering lines or not - half the time I don't trust my eyesight, heh.

The "white point shift" type flicker (when the CPU is busy) is most visible with a medium grey on the screen, such as LivingNeko's background.

We've only just got 1.29 here, so I wouldn't expect 1.30 (which I heard may have the fix) for at least a month yet
[HTC One X] middlep1:
There is a new 1.29 update just release this morning in Europe.

1.29.401.11

You are required to have 1.29.401.7 installed first, be on stock ROM and an network unlocked handset.

Apparently the update needs time to learn your backlight voltages to optimise itself over 7-14 days, but it is an update that specifically acts to fix the flickering issue. Fingers crossed it works.

next few days will tell...
[HTC One X] Cloudane:
Ooh, interesting.

TBH it sounds like a workaround for a hardware issue, but hey - if it works, cool :)
[HTC One X] alienslysly:
I just got mine a few days ago and I noticed the flickering as well, though I only noticed it when it's on lowest brightness, and only on my home screen where the clock widget is at. It's also weird that the screen flickers in intervals of 1 second, as if it's ticking to the clock's movement :confused:
[HTC One X] darqadius:
Nope... It doesn't fox the issue
[HTC One X] phil112345:
did for me. and my flicker was BAD. any colour, any brightness and you could see it and now absolutely nothing. took a few days to happen though... maybe 4 to totally go.
[HTC One X] xlys:
Same for me, flickering gone. :D
[HTC One X] Spl4tt:
it works with a custom rom on base 1.29 too right?
[HTC One X] Cloudane:
No difference here yet. We haven't had the update for long in the UK though so time will tell I guess. I was assuming 2 weeks as some exaggerated worst case
[HTC One X] phil112345:
as long as the base is 1.29.401.11 then it should
[HTC One X] JimmyEatFood:
Hmm, mine is now flickering on all light colours, not just white.
[HTC One X] JimmyEatFood:
Sending the phone back.
[HTC One X] mertzi:
does it flicker more for you when you touch the screen? For me it's most noticeable when i'm scrolling slowly, e.g. when in the settings menu, or the twitter app. Try scrolling very slow up or down in settings, for me it flickers a lot, but as said earlier only on low brightness. Another thing I can't understand, if not everyone has this how can it be software related?
[HTC One X] JimmyEatFood:
Nope, it's constant for me now. It's worsened over the last few days.
[HTC One X] JimmyEatFood:
I’m sorry to hear that you are experiencing difficulties with the display flickering. The reason for this is a software fault.

In order to rectify this I would like you to back-up your data and perform a hard reset please follow these steps:

- If your phone is tied to a Google account, your contacts, calendar events, downloaded apps, wireless settings can be backed up, if you have entered your Google account details in the initial set-up screens. Please go to , Menu, Settings, Accounts & Sync, tap on your Google account, then tap 'Sync now' you will see some spinning circular arrows for a short while, this just means your data is being saved to Google. When the arrows have finished spinning, the data has been backed-up (double check this).

- Or back up your contacts to the S.D card (For Android 2.1 or later) by following these steps; From the home screen tap All Applications. Scroll to and tap People. Tap Menu. Tap Import/Export. Tap Export to SD card. Select which contact Group to export (Phone, Google, SIM etc.). Tap OK.

- Available from the android market is a free application to enable you to back up your SMS messages if desired.

- Images and music can be backed up by plugging your phone into the computer and selecting disk drive mode. After this you can 'drag and drop' files to and from your computer to your phone. Make sure you select USB Debugging in Settings > Applications > Development before connecting your phone to the computer.

Now your phone is backed up we can perform the hard reset, all data will be lost that is not backed up on your S.D/SIM cards or online will be lost.

- Hard reset on Android From the Home screen, press the Menu key> Tap Settings> Tap SD & phone storage> Tap Factory data reset> Tap Reset phone.

The reason I have asked you to do this is because though it may seem a bit extreme this is the best method for dealing with your problem.

If this does not resolve your issue I think it would be best if best to either have the retailer replace the device or send the device to us for repair.
[HTC One X] nikzDHD:
Just going to LOL at that to be honest. It's not going to fix the issue I've hard reset twice and has done nothing. That's the first thing the technical support asked me to do over at phones4u I told them I've done it already and will not solve the problem!
[HTC One X] johnbhoy89:
ended up just phoning dialaphone to get them to send a replacement
[HTC One X] JimmyEatFood:
Same. Got to wait 3-5 working days for the pre paid envelope, and then the same length for the new phone. Going to be over a week until I get to enjoy my phone properly. In the meantime, I am still hoping that the OTA will fix it.
[HTC One X] nikzDHD:
Likewise buddy, let's see if an OTA comes before our pre paid envelopes. One other thing I've noticed is that when using the keyboard the button towards the bottom left in my example is the shift key on SwiftKey is a bit stiff to press like the screen is not registering my touch but a hard press solves this.
[HTC One X] dr9722:
That's the worst advice ever! IF this issue is software related then a factory reset will not make the blindest bit of difference. It's only going to cause people hassle getting there phone back the way they like it.

We currently have three options available to us:

1: Send back for a replacement.

2: Wait for HTC to release an update and hope it is in fact software related.

3: If it is hardware related then send the phone back to HTC for repair under the warranty.
[HTC One X] JimmyEatFood:
Not got that issue. I maybe imagining it, I maybe not, but I can feel the phone 'pulsing' ever so slightly in time with the flickering. :confused::D

Gutted it's got to go back, but to be honest my battery life is appalling as well so I guess it's for the best.
[HTC One X] joplayer:
I have this problem and after a full charge i can barely notice it. So maybe an OTA can solve it ;)
[HTC One X] Havoc2k:
sound stupid, but same here....

charged it... flickering gone.

i just wait a fews days, if it stays gone -> root and custom rom if not -> return ;)
[HTC One X] jimmga:
Hi all, first post here on the forum.

I'm posting here because I had a flickering screen as described above (worse on high brightness with grey backgrounds). I swapped it and there was NO FLICKERING on my replacement handset. I tested this by going into settings-->display-->brightness and checking whether the grey background flickered as it did on my previous handset.

I should also mention I checked the display model in the shop, and it wasn't flickering either.

My new handset, however, has a yellow discolouration in the upper left hand corner and I'll be returning it as a DOA this afternoon.

I am now in posession of my 3rd HOX in a week (!!!) which is also a DOA. Issues with handsets listed are:

Handset #1 - small hairline crack in the LCD underneath the glass. Noticed in the shop, swapped straight away.

Handset #2 - Flickering issue.

Handset #3 - No flickering, but area of yellow discolouration in upper left hand corner of screen. Returning this afternoon.

So either I'm seriously unlucky, or HTC have seriously deficient quality control. I highly doubt the screen flickering issue you all have is a software issue, since I have seen at least 3 other handsets which don't have it.

I'll keep everyone posted on how my next one goes.

Hope this helps.

UPDATE: I now have handset #4, which seems to be free of the previous issues (unless I just jinxed it). Thankfully the guys at the shop were very helpful and replaced it on the spot without any hesitation each time.
[HTC One X] znanev:
Can you please share which software version is your phone running with?
[HTC One X] jimmga:
handset #2 was ICS 4.0.3, bootloader unlocked via HTCdev and rooted with the clockwork mod recovery from MoDaCo. No custom ROMs were installed. The flickering was there before I rooted it, but it seemed to gradually worsen afterwards. Luckily I still got a replacement despite unlocking the bootloader.

All others were 100% stock 4.0.3.

Needless to say I'll be holding off getting amongst modding until a couple of months down the track, this is my first droid after being an iPhone user for several years.
[HTC One X] d33f:
Hmm doesn't sound good that the flickering is worsening after time, because today i also noticed flickering when brightness is on lowest settings + when putting the phone on charger. On max brightness (or auto) i don't have any flickering
[HTC One X] znanev:
Thanks.

I meant what is the software number of your latest, problem free device (#4?)

My software number is 1.26.401.2 - phone bought in UK a week ago. I am curious if HTC have silently fixed those issues in some of the latest batches.
[HTC One X] jimmga:
sorry, 1.26.980.3

Interesting...
[HTC One X] d33f:
Less tot none flickering with more charged battery

The more my battery is charged to less flickering is occurring it seems..

The flickering looks like it's having trouble to determine the exact brightness level, because sometimes when i play around with the brightness slider is goes to a much higher brightness level (above 50% when the slider is indicating is should be 20% or less) for a split second and then returning to 20% or less like it should be.
[HTC One X] JimmyEatFood:
When I place ny phone on a flat surface, and do g-sensor calibratotion, the spirit levels are moving loads. This seems to be done in time with the flickering, and the pulsing feeling I have posted about previously.
[HTC One X] znanev:
Yep, I found a thread where another user from Australia confirms there are no screen glitches and has the same software version as yours:

http://xdaforums.com/showpost.php?p=24691571&postcount=35

This at least is quite encouraging, I am definitely going to check some stores this weekend.
[HTC One X] wizard123:
I also have flickering but it only seems to be in apps on grey colours etc ive never seem it in the home screen wierd i have emailed HTC.
[HTC One X] Spl4tt:
damn, i have that flicker too.

and like wizard said, mostly it's flickering in grey zones..

that really hurts my eyes a bit when i stare at my phone and it's flickering..

no fun, would be nice to get an answer from HTC if this can get fix'd
[HTC One X] znanev:
So far I can't find a confirmation there is a device sold in UK that does not flicker. If anybody who has bought HTC One X in UK and the device is not flickering, can I please ask to share the software number?
[HTC One X] DazNoonan:
Mine is flickering at times too... It seems like just about every device that is out there is doing it. I still think its software based, and probably a setting to do with the LCD display. If its hardware then HTC are going to run out of phones...
[HTC One X] PaulBelfast:
It seems a lot of the initial launch day stock have the flicker.

I got mine on the 5th from Phones4U and my phone and some others sold that day have been returned to the same store.

The one I got today is totally flicker free on all colours. The screen seems totally different. It's not as blindingly bright as my original one but of a much better quality.

It may be software related but this would suggest otherwise.
[HTC One X] DazNoonan:
If you had of typed that 2 hours ago i would have said the same thing, however I have had this second device for a couple of days now and its only just started to flicker. My second one also looked slighter better than the first (although I could of just been convincing myself of this)... However the flicker is on this one but wasn't on the last one, the last one had different problems :(
[HTC One X] Fondue:
What's your software version Paul? Is it 1.26.980.3 too? I'm another early adopter (bought the grey model on the 5th from Carphone) and it's started flickering like crazy - I'm sure it didn't do so when I first bought it, but it definitely does now. Another possible connection is that for the first few days (pre-flicker) I didn't have a SIM in it, as was waiting to get mine cut down to size. I haven't yet tried removing the SIM to see if that helps - which would make me think it's a definite hardware issue. Sigh. If not, back to CPW I go on Monday.
[HTC One X] PaulBelfast:
My software is 1.26.401.2.
[HTC One X] Fondue:
Hardware it is. And back to CPW I go. Let's hope your screen doesn't start flickering again. So frustrating - I'll be pretty ticked off if this is a problem for some time to come; HTC really need to make a statement about this issue. I'm even considering swapping for an S now.
[HTC One X] ambrose7:
Pretty sure its due to the autobrightness settings
[HTC One X] DazNoonan:
Really? How bad is the flickering? Is it happen all the time and in all areas of the phone such as lockscreen, home screen and within apps or is it just when there is elements of brightness changing and possibly on app loading?

Like I said mine is flickering but only now and then in certain scenarios and I still believe its not a hardware issue (well one swapping the phone would sort). To me it really would lead to software whereby its causing the hardware to perform incorrectly.

Let us know how you get on with your replacement though... I hope that doesnt have the same problem and more importantly hope it doesn't have any worse problems that I know a lot of people are talking about.

Do keep us updated.

---------- Post added at 04:58 PM ---------- Previous post was at 04:56 PM ----------

Yeah that would make sense... I feel it has something to do with the brightness for sure as it seems to happen as it slightly changes brightness and/or when you are loading an app where the screen will dim slightly during the loading and then become bright again.
[HTC One X] JimmyEatFood:
To those that have constant flickering, could you possibly open the G-sensor calibration and see if it is wobbling like crazy? Thanks

Also, I would love to here from any devs regarding this issue.
[HTC One X] NFCZone.net:
Flicker gone!

I had the same flicker as the rest of you guys, but just flashed the new ROMeOS 1.1.3 rom and now it's GONE! :)

Maybe it's the NVidia Power Management Control fix included in the rom that fixes it? Don't know, all I know is that screen looks great now :)
[HTC One X] JimmyEatFood:
Snap.
[HTC One X] DazNoonan:
Indicating its a software issue and not hardware then for sure otherwise this would not be possible... Sounds like the ROM fixed the problem and hopefully an OTA from HTC can do the same!
[HTC One X] JimmyEatFood:
I'm not wanting to go away from Stock at this stage due to worrying that dial a phone won't accept my exchange If I do. Cheers though.
[HTC One X] Fondue:
It's mostly noticeable on mid-greys (e.g. battery chart, tweetdeck, etc), but also just looking at photos (especially on lighter areas), playing Words with Friends, etc. Now, I know I'm a quite susceptible to flicker (I hate monitors set to 60hz) so it could be "just me", which is why I sought out other people to see if they had the same issue - and found this thread. My previous phone was an HTC Desire - the early model with the OLED screen - so I'm now wondering if all LCD screens are like this, but I've not noticed before! I tend to get migraines now and then, so I'm wondering if it's all related.

Not sure it's an auto brightness thing however - if I use the brightness slider, I can see the flicker at all levels, and especially at maximum brightness.
[HTC One X] DazNoonan:
You don't have to go aware from stock; you just have to be prepared for OTA to fix the problem. If another ROM has fixed the issue then there should be no reason that OTA won't fix it. I honestly don't think changing your phone is the option; but this is obviously your call and nobody else's.
[HTC One X] wizard123:
I'm not so sure its the rom as i have done the nvidia fix manually and still have the issue ?
[HTC One X] DazNoonan:
It might not only be that fix that needs doing to fix the problem, that could simply be part of the resolution?
[HTC One X] Fondue:
HTC have until Monday (!) otherwise I think I'm going to trade it in for an S instead. Am finding the X just a teensy bit too big anyway.
[HTC One X] NFCZone.net:
To flick or not to flick?

Anybody who also flashed ROMeOS 1.1.3 and can confirm that flicker is gone??
[HTC One X] d33f:
I'm questioning the same indeed!

Have you tried asking in the ROMeOS Developer thread ?
[HTC One X] NFCZone.net:
Will do.. :)

My flickering was worst when opening Google Play when screen was all grey (When opening Google Play and it hadn't loaded fully) and when starting Facebook app and was at the all blue login screen.. Anybody recognize this? Just want to be sure, we are talking about the same flickering..
[HTC One X] JimmyEatFood:
Yeah I have the same. More noticeable on any solid colour. Its worse with lighter colours.
[HTC One X] d33f:
I had the flicking even with white colors.. especially in the SMS app/settings menu, but only on low brightness.. full brightness didn't flicker at all. Furthermore the flickering was worsening when the battery % was decreasing
[HTC One X] DazNoonan:
Yep same here in all those places...
[HTC One X] wizard123:
Get this tho, if you install lcd tester from the market which uses static gradient images i see no flicker at all, it is only visible for me if the screen is refreshing or im inside an active app like play store for example, im really not sure this is a hardware fault but i guess until htc actually have a bit of respect for their customers and make an official statement we wont know
[HTC One X] JimmyEatFood:
from the HTC facebook page, when asked if it was software or hardware related.
[HTC One X] DazNoonan:
Good bit of info, thanks mate.
[HTC One X] johnbhoy89:
I downloaded the LCD test and it is really clear on the GREY image
[HTC One X] JimmyEatFood:
Still as bad as normal for me.
[HTC One X] DazNoonan:
I've just ran this and get the same results as you...
[HTC One X] Havoc2k:
me phone gets replaced by vodafone germany.

thanks to them there is no "gap". some pickup the old and i get the new one ;). that's good news. just saw the yellow glitch at the top of my screen, time for this phone to go.

i just wondor why htc shipped this devices, is there no quallity check at all ?
[HTC One X] predator21:
I too have this problem. But its not constant. I guess its software related. After installing lcd test all colors looked fine n solid, which means the issue is software based as hardware never differentiate. Wait before jumping to conclusions, the best place i can home down to is the problem of nvidia settings specially refresh rate. The flickering is nothing but a faulty refresh rate value not hardware issue. Advice wait.

Hi all. I wanna know if this firmware number 1.26.xx is only for UK phones or is this firmware number globally?

Sent from my HTC Desire
[HTC One X] DazNoonan:
Fully agree with this statement ; it has to be something to the OTA can fix as just about every person I have spoke to with a OneX has noticed this at one time or another.

---------- Post added at 09:36 AM ---------- Previous post was at 09:35 AM ----------

Global... The 1.26 is the same everywhere its the last two bits that change.
[HTC One X] wizard123:
I think its software too but the nvidia service does not fix the issue for me i can confirm.
[HTC One X] mohsinraza:
And phones with 1.26 are having problems and 1.28 phones are problem free, right?

Sent from my HTC Desire
[HTC One X] JimmyEatFood:
Unsure.
[HTC One X] d33f:
I too can confirm that running LCD tester does not show any signs of flickering... All the colors/greys are flicker free.

Edit: is it just me or does the lcd tester shows signs of screen/color banding ? i also notice this in Sense itself sometimes.

I do mean real color banding like you can see every transition in a gradient.

Serious screen prolems

I bought a HTC Once X and experienced some flickering on grays, for example when clicking on the homebutton twice, where you can see the gray empty screens. There is also a problem when watching youtube on fullscreen - there is some screen glitchng but as soon as i play video with the player controlls the problem disappeared. So i thought it was hardware error, and i returned the phone and got a new one. The same problems appear again on the the second phone. I hope this is a software/driver issue. The screen flickering also appears when you change window in the browser - the animation between two browserwindows. I have uploaded, several examples on youtube, so click on all to see the big picture.

Has anyone experienced this as well? I had it on both my phones, and i don't feel it's any use of returning the second one.
[HTC One X] DazNoonan:
Yes mate the flickering is the same issue most (if not all) of us are having... I have had it on both my phones now too, although my first phone did have a few more bugs too and thankfully this one only has a couple.

As most people have said we believe it to be software and we all think/hope that the OTA will resolve the problem when it arrives.
[HTC One X] dan_ep82:
i think there are 2 types of 'flickering' being talked about here, 1 is the like static wave at the bottom of the screen and 2 is what i have where the backlight seems to flash during auto brightness!
[HTC One X] DazNoonan:
Yeah your right... The wave one is the major problem I believe that not everyone is having (I've not had this yet). The backlight one is the one that most people are having, if not everyone.
[HTC One X] JagSem:
Mine is flickering when set to lowest brightness setting. When I take it just a bit off minimum it tends to not flicker.
[HTC One X] d33f:
Same here. Only the lowest setting and the settings one notch higher gives me flickering, above that no flickering at all
