[HTC One X] piero0402:
I've got the same 'problem', don't want a new phone cause of that, only with my phone it gets that problem in the browser and in the menus sometimes, but knock on wood it doesn't happen anymore last few days :D
[HTC One X] ac3dts71:
I have got the flickering issue on grey background as well, most notably in the background on screen brightness settings screen.

The phone is three weeks old and i would like to send it back but i have unlocked the bootloader through htcdev.com, anyone managed to exchange one to one successfully with the device rooted?
[HTC One X] DazNoonan:
I'm sure I'm starting to see signs of my third handset flickering now. It's not as extreme as the last one and only very faint but it's still there, well unless I am convincing myself of it (HAHA). Going to monitor it as its barely noticeable and it really isn't anywhere near enough to make me contemplate changing again.

The 1.28 update for Vodafone comes out later today so going to see what that brings too.

---------- Post added at 02:34 PM ---------- Previous post was at 01:41 PM ----------

I am starting to think the flickering is linked to the heat of the CPU/GPU/Battery (either one or all of those) as normally it begins when the phone is starting to feel hot or the battery is running at a high temperature.
[HTC One X] lawrence750:
remember it gets worse over time, im on the 2nd replacement, and it wasn't really noticeable until today, now it does it almost constantly..

I'll be replacing until they either confirm 100% that it's software, or I get a device that doesn't flicker at all, ever.
[HTC One X] DazNoonan:
Well I have until Thursday to change mine again which would then be for my 4th handset if I did actually do this. There is an OTA out later for I'm going to update to that and see how that goes first etc... before making any hasty decisions.

Really don't want to have to get a 4th handset as I do love this phone, and the flicker is barely noticeable to the point where I think I'm convincing myself its there due to having the problem previously. It doesn't happen in anywhere near as many places as the last handset.
[HTC One X] lawrence750:
it's definitely good to know that the ota is coming out today :) my third replacement coming tomorrow, the place i noticed it on 1st and 2nd replacements was when i turned the phone on for first time, it flickered on those splash screens, and then when plugging in the charger. then for a few days it didn't flicker at all, even sometimes it didn't flicker when plugging charger in, but now today was browsing internet, and it was flickering like crazy

I'm just scared that if i go over the 7 days, then maybe after a month or more , the screen will conk out altogether and just not turn on or something (as the problem gets worse over time) and then at that point will need to go to htc for repair, where they may well fix the screen, but ruin the rest of the phone in the meantime (wobbly camera or scratch it etc etc), i've only ever had bad repairs before so will try and avoid having monkeys taking my stuff apart lol.

EDIT: i personally haven't had HTC repair my stuff before, but my mate had to send his sensation in once, and they sent it back with the screen still hanging out of it!!!!!
[HTC One X] oxfordmark:
Well I connected TMobile. The girl I spoke too said she'd not heard of this problem. I called the store and they are getting a new delivery on Wednesday so I can exchange it then.
[HTC One X] DazNoonan:
I fully agree with everything you said. Going over 7 days would be a nightmare. I will monitor it for the next 48 hours and see where it goes from there. Should have the OTA on it at some point tonight providing they do actually release it.

In all honesty though, I just can't believe HTC are saying nothing about this.
[HTC One X] saih:
I've seen backlight flickering on my device after the ota, but it was faint. But over the last days I've really kept my eyes on this problem as it is the only one I've "suffered" from. But the flickering has completely dissapeared! I've checked regulary at all kinds of battery percentances, all most drained and completely charged, on or off the charger. What this means, I don't know but I think it is mentionble.
[HTC One X] DazNoonan:
Appreciate the reply, this is what I am hoping from mine. My second device's flicker was really bad noticeable in lots of places on the phone. This one is barely noticeable but definitely there.
[HTC One X] evo6:
I'm on 6th handset. All of the other ones had flicker, i think most of the ones in the UK have flicker problems because 2 is a coincidence 6 is a statistic! I hope this one does not flicker as well, probably will though.

And I also think that people are confusing the flicker problem for the graphic glitch, the flicker problem happens on grey back grounds, the glitch problem is defiantly a software bug. But who knows even the flicker problem might be a software bug.

I am convinced that this is caused by heat though. Wack your phone in the freezer for 30 seconds and watch the flicker go away.

[HTC One X] audioslim:
I've just suddenly noticed slight flickering on mine, especially prominent when the screen dims to show a dialog box etc.

Never seen it before and I've had the phone 2 weeks now (ish).

[HTC One X] DazNoonan:
Yeah I posted a few posts back about it possibly being heat related. I noticed my battery temp was above 40 degrees and it was flickering, back down at 29 degrees now and there is no flicker. Can't believe your on your sixth handset :(
[HTC One X] mwilky:
Sixth handset wtf!

I've just sent mine back to where i got it from for a replacement, this is my first device so if i have your luck the next few will be getting returned again!

Really thought HTC would of been better than this.
[HTC One X] jonstatt:
It's not always heat related. As I said before in my case its CPU and auto-brightness related. There is a very specific range of brightness where I get flicker ONLY when the CPU usage is high such as rendering a web page. It stops flickering once the page has finished rendering. Dimmer brightness, no flicker. Brighter, no flicker. Just a specific range, and in addition, the same brightness level with auto-brightness disabled doesn't give flicker.

I would bet that nearly every phone has flicker under specific circumstances. But due to tolerances, each phone will vary slightly on what induces it. I believe this is hardware and related to voltage regulation of the backlight. I would be surprised if there was a cure for this in firmware unfortunately. I think its a bad choice of component for the backlight voltage regulator.

EDIT: I have seen both phones with the whiter screen and the more yellow variant flicker. The voltage regulator for the backlight is not part of the screen itself.
[HTC One X] BarryH_GEG:
I've seen two from Handtec. Neither flickered. One I only saw for a couple of days so can't comment on longevity. The one I kept is 10 days old and doesn't flicker even when hot and under high load (Glowball). The poll running was showing about 75% of phones w/o issues and 25% with.
[HTC One X] oxfordmark:
I just showed my girlfriend and she said she can't see it. Maybe I'm seeing things..
[HTC One X] Ripley:
My first one flickered, sold on ebay. My new one is flawless. I made sure it was made in Taiwan and not China, maybe that helped.
[HTC One X] evo6:
All six of mine were made on Taiwan so it's not that. No flicker yet I give it until tomorrow
[HTC One X] oxfordmark:
Realistically could an OTA update solve it
[HTC One X] DazNoonan:
Mine also says she can't but I keep telling her she's crazy as its definitely happening.
[HTC One X] audioslim:
If i put the wallpaper as the HTC one with the Mountain/Volcano in the background with cracked ice or something in the foreground, then on a desktop screen with nothing on it, the screen flickers, slightly.

Put the red beats screen on (with a lot of black) and no sign of it.

If I go to brightness settings , where it kind of dims the sceen apart from the input box, well the whole screen flickers pretty badly (but only the white part of whatever is getting dimmed. Same happens on font size menu. Only noticable really where a lot of the screen is dimmed.

Quite odd really, it doesnt look like its usual lcd power type issues as such as it doesnt show on bright white menus/screens until something else overlays it.

Inspires a bit more confidence that it can be corrected.

[HTC One X] Maroon Mushroom:
Wait.... 6?
[HTC One X] evo6:
Yep 6
[HTC One X] optiknerv:
Well I'm not holding up much hope for a handset that works within the next couple of months then!! My second handset is coming tomorrow but I won't be in to receive it so I will have to collect it on wed. If the flicker shows up instantly (which it usually doesn't) then it would take around until the end of may to complete another 4 returns with dial-a-phone!!! :mad::mad::mad::mad:
[HTC One X] oxfordmark:
Its almost like if i look at one part of the screen i can see a flicker but when i look at it, its not there...

Think my brain is playing tricks on me.

My phones will be under warranty so in 6 months should the problem get worse i can take it back for repair.
[HTC One X] vegetaleb:
I wont go to casino with evo6 :eek:

Or he's a samsung spy :rolleyes:
[HTC One X] jonstatt:
Hmm...for those with flicker, have you validated if the behaviour changes if it is currently on charge....or if the flicker is less on a full battery? I can't get the flicker even in my "special" scenario for my phone that I found, if the battery is above 45% full.
[HTC One X] arnie105:
No screen Flicker

I have had my One X about a week now and don't appear to have an issues. I think I'm having the normal screen dimming especially as I have flashed a LeeDroid Rom and applied the Tweaks screen dimming script.
[HTC One X] wietse1988:
I have the screen flicker as well. I've only noticed it with the color grey. I'm using the auto brightness settings. When I open the play store or gallery the screen is sometimes a moment grey while loading, at that moment the grey is flickering. I have not noticed any flickering with any other colors. Do you have flickering with different colors??
[HTC One X] DazNoonan:
It's the same situation you are having for just about everyone mate. Only on the grey backgrounds.
[HTC One X] hamdir:
on the other hands 6 bought here in my country and non had the flicker...different serials, build origins, colors and regions, non have the flicker

i think flicker is already fixed in factories, very early units might have it

i think you guys on reptitive replacements should ask the following from your source, please take it back and give me a fully tested and working on unit, let them open it and test it for u
[HTC One X] oxfordmark:
Only on grey.
[HTC One X] oxfordmark:
I contacted HTC about this and got a reply about an hour after:

Thank you for contacting HTC regarding your HTC One X. My name is Robert and I am a Technical Support Agent for the HTC Written Team. I understand that you are currently experiencing difficulties with the screen flickering. I am sorry for any inconvenience this may have caused you. I believe that the reason for this could be due to 2 main factors. Either a Software fault or a Hardware fault. But before We can determine the fault we will have to troubleshoot the issue first.

In order to rectify this I would like you to perform the following actions:

) Please can you turn off all 3rd party applications and UN-install any which are unessential, As they may be causing a software confliction.

Menu - settings - applications - manage applications - all - select - un install.

Menu - settings - applications - running services - select - stop.

) Please make sure your device is fully up to date:

Menu - settings - about phone - system software update - tick box - check now.

To assist you further I have attached links to the HTC Support Site which will enable you to work through the above step by step:

http://www.htc.com/uk/help/htc-one-x/

Once the above has been completed you may be required to do a factory reset, for your convenience I have detailed the steps below:

http://www.htc.com/help/www/howto_iframe.aspx?id=141916& type=1&p_id=440&fromsearch=1&q=reset

Should the above fail to restore your device to full working order, I would advise returning the phone back to the retailer or a replacement as this is possible within the first 30 days dependant on the retailers policies. Thank you for your patience and co-operation, as I understand how frustrating & time consuming this can be. I hope that this information meets with your requirements, should you have any further questions please do not hesitate to contact me again.
[HTC One X] lawrence750:
i've noticed it happens on every background colour, just it's easier to see on the grey backgrounds

---------- Post added at 12:47 PM ---------- Previous post was at 12:46 PM ----------

all the above has already been done, tested in safe mode, tested after factory resets. just send it back
[HTC One X] DazNoonan:
Same here... And still the problem persists.

Oh and yeah its there on most background, but very noticeable on the grey.
[HTC One X] oxfordmark:
Thing is people have had 4+ hand sets and it does it on them all. Maybe it's a software error
[HTC One X] DanteGR:
I'm officially going nuts with this flickering prob.

Tbh i believe maybe i would not have spotted it if i haven't read it here. In screen test app, on gray color it's fine though. I only notice it on dim white (cause of autobrightness) backgrounds like on tapatalk or on the settings of the phone.

It's like the screen is veeeery mildly flickering though... Maybe that's normal?

Is it worth a change??
[HTC One X] wietse1988:
I have it with different colors as well, only grey is the most notable. If I open the Facebook app or xda app the blue and gold colors are also flickering. I've downloaded the AnTuTu tester and did an lcd test. At some colors you see a little flicker, at the grey color the most. I think it's a software problem, I hope there will be a fix soon.
[HTC One X] DazNoonan:
To be honest, I noticed it on my second handset as that one was really bad, had I of got this third handset before seeing the problem first hand I might not really have thought much about it. This third one flickers but not bad at all, and its very intermittent, its the fact I know about the problem first hand the the fact I've read so much on here that I know its actually a big issue.

Are you within your 7 days and able to change? The more faulty handsets HTC get back the more they will have to acknowledge the problem and do something about it, so i think the more that go back with a problem the better rather than people holding on to them and hoping for a fix.
[HTC One X] ac3dts71:
On grey and light orange, like skin colour..
[HTC One X] villandrew:
Has anyone actually had any success in returning their handset for a new one?

I am about to call up and request a 3rd, however, I feel that T-Mobile UK still have the fault across all of their HOXs...

(HT23 - Flicker on grey backgrounds mostly)
[HTC One X] DanteGR:
Yeah i have about 10 days left for my DOA period so i will test a bit more before replacing it as i am rooted with a custom rom and want to avoid the hustle of relocking the device if possible..

EDIT: Could somebody please send me the default picture that came with the phone that has the sun and snow in it? It has been mentioned before and i want to test there also. I have deleted it as i didn't want it :D

Many thanks in advance guys :)
[HTC One X] DazNoonan:
The image should be attached for you :)
[HTC One X] DanteGR:
This is the picture that some people have the flickering on? I thought it also had snow in it??

Thank you for posting my friend :)

EDIT: Silly me i thought the snow was water lmfao!!! :D

Btw i have no flickering on this image at all. Maybe i'm ok then..
[HTC One X] wietse1988:
In the picture the sun flickers at my phone.
[HTC One X] DazNoonan:
Your welcome, and yeah I originally thought it was Water until I took a closer look. Glad your's isn't flickering on that image.

This is not good, the image should not have any flicker and if it is then you unfortunately have the same problem that most of us are having. Sorry :(
[HTC One X] The-Last-Hylian:
I have quite a bit of flickering in that picture, I also have it on the Recent Apps acreen from the hotkey.
[HTC One X] oxfordmark:
I think the sun flickers on my phone.

Does it flicker when you zoom in on the sun?
[HTC One X] DazNoonan:
Same here and again the same for most of us. With this many people having the problem I just hope and pray its software and not hardware as I know quite a few people will have had the phones past the exchange date now.

If I zoom right in it only flickers around the sun on the grey area. Which makes sense as the most noticeable place anyone is seeing this flicker is on grey backgrounds.

If you open this on your phone and scroll down to the large image does that flicker too? http://www.lagom.nl/lcd-test/inversion.php
[HTC One X] faizalmzain:
It's happened to me once and never came back since then.
[HTC One X] DazNoonan:
Again another suggestion towards software... I mean if it was hardware controlling the problem it would be happening pretty much all the time on all the screens of the device. If its software controlling the hardware then it would be intermittent and happening in some areas but not others; which seems to be the case for most people!
[HTC One X] cawith:
I started experiencing flickering too. The situation where it is most obvious on my device is, when I go into the settings -> screen etc. and press the screen brightness button. The this dialog shows and all the grey area around this dialog box starts to flicker. It is more noticeable the brighter the screen is!

Are you guys also having that flicker?
[HTC One X] NFCZone.net:
Flicker gone!

I'm just gonna copy + paste my respond to the other 'flicker-thread':

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!

Anybody who can confirm??
[HTC One X] evangeloschr:
Screen flicker here when using browser mostly on the right corner pressing the menu button or on the back button on the left button. Sometimes there is also flickering when i swap from browser to another app.

I have contacted htc and they reply me this:

Thank you for contacting HTC.

With regards to your enquiry, kindly note that, as you have the phone for only 2 days, you can go back to your retailer and swap it for another one. Just this time make sure to test the new phone at the store, to avoid the same problem. If they however refuse to swap your phone, you can contact our Repair Center for further support.
[HTC One X] jonstatt:
This may be a coincidence or perhaps not. I have only seen one with flicker but it also had a screen much brighter than others I have seen. It may be a faulty voltage regulator for the screen backlight and it shouldn't be that bright. Having said that, it was also the screen with the purest whites. All others I have seen have had more yellowy tints to white.

The "real" hardware flicker issue is when you can see it flicker regardless of colour, but most noticeable on white. It applies to the whole screen and it looks like a light bulb on its last legs....as if its about to blow. It is not a graphic glitch.
[HTC One X] optiknerv:
If I go to the auto brightness settings it flickers, close it and its fine, open it again and it flickers.... etc etc. I cant be bothered with the hassle of returning my phone so i really do hope its only software.
[HTC One X] georgemaier:
just adding my two cents. I got the One X on three about 5 days ago now and have the screen flicker issues. I think it is power management related as when loading apps I notice it, when picking up things to drag and drop i notice it, when something on the screen is set to refresh regularly I notice it, but not when phone is idle or using apps that don't use much power (ie. messages email ect...)

I have noticed a similar occurrence on my HP Envy 14 Beats Edition laptop when rending HD video out

I really don't want to go through the hassle of sending my phone back in the post and getting a new one, especially as this will mean me going a day or two without a phone, but I'm unsure of the nature of this problem, and I don't want to lose my warranty, find out it is something that, for sure, cannot be fixed by software updates and then have to put up with it while everyone around me got ones that work fine.
[HTC One X] mertzi:
If htc tells us to DOA then I think you should use that oppurtunity, I dont think three will even check the phone as they dont lose anything from a DOA. I bought mine at swedish three and Im sending mine back tomorrow. And if the next one is bad too you can do a new DOA. Dont you have a backup phone?
[HTC One X] d33f:
My problem is exactly like you describe, also i think it's software / power management related, since it only happens with lowest brightness level and at a certain battery level
[HTC One X] joplayer:
On my side I'm gonna contact the website where I bought my One X from and ask them how much time I have to ask for an exchange device. If I can have the OTA first I'll take the chance :) Otherwise I guess I'll have to live without a phone for a week...
[HTC One X] optiknerv:
For me it is more noticeable at higher brightness levels than at lower levels. I went to a local o2-uk phone shop today and pretended to want a new contract just so I could have a fiddle with one of their stock. I found that it did not have the flicker that I see with mine! It was however brand new and when I say that I mean it was literally its first turn on because it went through the setup. I can't remember mine having flicker when I first got it but maybe I was just so excited with my new phone I didn't notice it OR its something that appears with a few days use???

Either way I have requested a returns envelope from where I got my device from.
[HTC One X] DazNoonan:
If your device is anything like mine then there was no flicker when I first got it. I noticed it after around 24-36 hours of having the device; so its definitely something that happens over time. I didn't.have my first device long enough to comment on that one unfortunately.
[HTC One X] lawrence750:
Just noticed the flicker start happening on mine, I would say it's a software problem tbh, put it at manual max brightness, and I don't see it happening, put it back on auto and it does it again. Seems like it's just another bug with the auto brightness or something
[HTC One X] nikzDHD:
Mine started of like this then over the next few days it was apparent on all brightness levels.
[HTC One X] joplayer:
Exactly the same. Only noticeable on low light greys at first. Now I notice it on many mid grey colors. That is really disturbing to watch...

Looks like many of us have this issue and no way to reach any competent HTC staff for infos...
[HTC One X] lawrence750:
Another thing I just noticed, it hasn't been happening for the past few hours, but now just started again! Surely this would imply its software? Bloody hope it is anyways
[HTC One X] t.sjostrom:
I really hope it is software, I have screen flickering on all brightness and battery levels, the phone was fine for almost a week, then I got this...
