I had the flickering screen issue on grey backgrounds (recent apps screen, battery graph, google chrome effect when you select address bar) when the brightness was greater than 30%.

After wondering whether to wait for the .11 update, I decided to try exchanging the phone as the update may come past the 28 days I have to exchange the phone on the spot at a Three store. Got the new phone today and touchwood there are no issues with it and the screen no longer flickers.

It's strange how this is likely to be a firmware issue, however not all handsets with the same firmware have the problem. The demo phone in the shop with the same firmware I had doesn't flicker, and the sales assistant said that someone had brought a phone in with the same issue a week ago. Apparently after updating the software on that phone the issue disappeared, but he said that my phone was on the latest firmware so thought it would be a hardware issue. Anyway, I'm happy with the phone now - no longer have to worry about whether the update will resolve the problem. I hope that the .11 firmware update does solve the problem for others who are waiting, hopefully Three won't take too long to OTA it.

(Final?) update - 21 May

I know that it has been said many times already but I just had a reply from my contact at HTC (he's been off for a few days) confirming that 1.29.xxx.11 will recalibrate the screen over the course of a few days. I had no reason to disbelieve anyone else's info but to hear it from the horses mouth (from my perspective) is more final.

Let's face it... 3 updates in quick succession, so many positive changes, all promises kept, HTC F****in' nailed it. Eat your heart out Samsung!

I know HTC are as grateful for to us for reporting in detail, patience and loyalty as we are with them for the resolution, so thanks to all of you too!

I know some regions will still be waiting for this fix but you can rest assured that the light is not only at the end of the tunnel, but is blinding and approaching fast.

---------------------------------------------------------------------------------------

If you feel that you benefited from the time I spent creating pressure, and then communicating with HTC, keeping them, and you, updated on the screen flicker issue, and if you can afford it, please buy me a pint, or multiples thereof!

thanks, lets see if my phone stops flickers. On xxx.11 now for 4 days... still flickering on greys

---------- Post added at 07:48 PM ---------- Previous post was at 07:46 PM ----------

Do/did you use a .11 stock rom? or a custom rom from here?
[HTC One X] dryspuri:
Hey In OP u have mentioned this corruption or bad VHS player like display problem, did HTC mention about that, or we have to wait for another update, Also Live wallpaper stopping is most annoying for me as it gives impression that I am using some make up copy of original and there is some substandard materials used in HOX. Please do reply about that, Thanks!!
[HTC One X] farnsbarns:
The corruption was fixed in 1.28 although I did manage to get it to happen once after 1.28 but not since the first reboot. Do you still have it? if so, what software version are you running?

The live wallpaper issue I believe is a deliberate measure by HTC to keep sense smooth (just mho). I'd like to see it as an option as I have seen in some launchers. Leave it a couple of days for my pathetic grovelling thank you message to sink in and I'll ask if there is any info/answers about it.
[HTC One X] anoniemouse:
I must be one of the lucky ones, so far my phone has been ok since day one.

The only thing i have got from the updates have been improved battery life, but then that is a big PLUS.
[HTC One X] dryspuri:
Thanks for that, I am on 1.28.720.10, for some unfortunate reason, I was in India when I bought this and regret it deeply as there is no update after that.

And I am still having this corruption, I was looking for 1.28.720.10 RUU but apparently that also is not available so you have to flash stock 1.26 and then phone will update itself, as i thought might be that will go after flashing the whole firmware!!

thanks for the info though
[HTC One X] AUXRVIII:
Hi,

I just got my HOX yesterday, came with 1.29.751.7. when I checked for an update it came back with 1.29.751.12. Does anyone have any info regarding what is the difference between 11 & 12?

Thanks
[HTC One X] Chim89:
I installed the 1.29.401.11 update yesterday around midday and left it on full brightness since then. It has gone through a full charge, and I am reporting a slight difference to a reduction in flicker. On grey / negative photos, there is still a visible flicker although significantly less than yesterday morning.

Anyone looking to test the flicker, take a negative photo if there is not a flicker there then the problem should be rectified.

I love the device, its a shame we are having to wait impatiently for updates. Although, lets hope its the last of it.
[HTC One X] LittleH79:
Is this an ongoing thing?

I mean when using custom roms do you have to keep doing the brightness trick for longer periods of time each time you're flashing a rom and wiping?
[HTC One X] bigoliver:
Good question. I guess once it's calibrated correctly it will stay that way? If not I can live with the flicker for a few days if I know it will steadily improve and fix itself.
[HTC One X] farnsbarns:
I have wondered this. Presumably some values are being changed, so presumably a Rom base lower than 1.29.xxx.11 will bring the issue back and a Rom base above 11 or an ruu will mean calibrating again. Those shouting about RUU's instead of waiting a few days may be forced to rethink.
[HTC One X] LittleH79:
Thankz, my thoughts exactly :)
[HTC One X] middlep1:
I think we need to get some of the OneX Rom devs in on this discussion to see if they can shed any light on the matter. Mike1989 and LeeDroid are the big 2 I can think of.

I wonder where calibration data is stored and if it is affected when you do a full wipe or wipe Dalvik cache/battery stats etc... will it wipe the screen calibration data too?
[HTC One X] plunderclat:
Thanks for pushing them for information farns!I tried taking Samsung on about screen burn on the pentile displays of the nexus and note, after owning them for only 3 months and after weeks and weeks of written correspondence, they concluded that any reports of hardware failures,regarding their devices, would have to come from credible sources like cpw or watchdog, as the folk on forums such as this could be lying. They also added that customers reporting issues on their 'own' forums couldn't be considered as credible! And. Therefore action would never be taken. They even refused to repair my screen on my note, because it had a dead pixel or 'spot mura' , and I was told by a guy from gateshead, called 'Michael Irwin' that I would have to have a minimum of 8 dead pixels in order for them to consider a repair.

The reason why I mention this is because reading through your statement, it brought back the taste of those 'sour grapes' I got from Samsung.

Anyway, I'd say; HTC: 1 samsung: 0.

I'm very happy with my one x, and I hope more people like you, continue to remind those giant corporations that; while they are fighting to sell their latest device before one another, they should consider that the whole point of this is to make their customers happy, since they are what they are, because of us!

Good job mate :) and I hope we can agree here, that Robert Collins was just a twat in a suit.
[HTC One X] hamdir:
Those who are still suffering from flicker issue even with the latest update, i suggest trying the latest CM9 on Modaco

it includes advantage back-light controls to deal with flicker
[HTC One X] farnsbarns:
Can I add to this that HTC have said up to 14 days for the flicker to disappear. Not saying don't do it but maybe don't do it yet if this is the only reason.
[HTC One X] exCluSive1:
Are you serious? Can you be more specific : what tweak/change did cm9 implement that others did or could not? Have people reported that this really worked, even after trying 1.29.xxx.11?
[HTC One X] exCluSive1:
So far, I've been waiting for almost a week with a few hours (and one overnight) of 100% brightness steps that a lot of xda members recommended. And still, screen is still flickering and especially on grey backgrounds.
[HTC One X] hamdir:
yes on CM9 012 there is a very in-depth and explained backlight control options in the display settings
[HTC One X] exCluSive1:
I'll check if I can find the right thread
[HTC One X] miniterror:
Just flashed jan his rom as its .11 based and still have the screen flicker:s

Dont think software is gonne fix it:(
[HTC One X] exCluSive1:
Can't find any post regarding this flickering issue... Are you talking about TripNraver's? http://www.modaco.com/topic/353715-20-05-rom-cyanogenmod-9-endeavor-unleashed-012
[HTC One X] ViDtje:
I have had .11 for almost two weeks now, and at first I was sceptical, but it actually worked for me. I don't have the screen flicker anymore.
[HTC One X] ste1164:
You need to wait for a bit, HTC said it won't happen instantly.
[HTC One X] farnsbarns:
Almost a week? So... What? 5 days? 6? Somewhere between 1/3 an less than half what HTC say it will take.

Look, I don't know better than anyone else if HTC are right but I'm not going to start saying it doesn't work until day 14. The CM9 thing sounds interesting though. Wish we had more info, can't find any, anywhere.
[HTC One X] miniterror:
Lol, it looks soooo, uhhmmmmm, stock:s

And i wonder why its not instant? Software doesnt adept itself while using:s

Just set it up once and then its done:s
[HTC One X] kempas:
I only read the first post so this may have been explained later but what is this 28 day return period?

If you are in the UK, and from what I read it appears so, aren't you covered for a full refund up to at least 6 months after purchase under the sale of goods act anyway?
[HTC One X] bigoliver:
Its interesting that the flicker took upto 2 weeks to manifest its self. I guess the first software slowly calibrated the screen wrong.
[HTC One X] Albert Poon:
This is the reality, hardware requires run-in, your car, your audio... throw software in to make the pattern not so uniform? Longer run-in time is expected.
[HTC One X] cjm1979:
Wont it affect how long it takes to work based on how much the user uses the phone as well, i.e. the screen needs to be on to calibrate?
[HTC One X] exCluSive1:
6 days, yes. I'll wait another week and report back afterwards.

@hamdir, please help us finding the cm9 thread you were talking about
[HTC One X] dmestriner:
I posted this already a few pages back, but here it is again:
[HTC One X] exCluSive1:
Yeah, that's what people on forums say but I haven't seen a single changelos or post from HTC themselves about this.

Let's wait till Hamdir answers about the CM9 thingy regarding the flickering screen.
[HTC One X] Chim89:
Update: Screen flicker has decreased significantly after 48 hours, although I still detect a hint of flicker on negative photos. Much improvement, update was installed on Monday.
[HTC One X] VextoR:
still no update for Asian HOX :( Hate that flickering
[HTC One X] farnsbarns:
My findings exactly. Also since Monday.
[HTC One X] Torc'qua:
I received the update 1.29.401.11 around 6pm last night and within the first 2 hours, the screen flicker had completely gone.

I always noticed when loading Play Store as the grey screen is noticably easy on the eye to see the flickering, yet it's as smooth as a button.
[HTC One X] farnsbarns:
That's an interesting idea. Hadn't thought of that, makes sense .
[HTC One X] barryb20:
Hi All,

well I had no flicker but now after 1.29.xxx.11, which I got around a week ago. I noticed flicker on the SMS app and settings app almost every time I touched the screen, most noticable when there is a white background.

The battery was about 25%, did a reboot and the issue stayed the same had already switched off auto brightness previously (brightness set under 50%)

It has however appeared to have gone away since I charged it. I will see if it returns when the battery gets down to that level again.

My One X has been working well since I got it in early April :(

Barry
[HTC One X] Spl4tt:
probably the update recalibrates even the well working screens?

this would mean the flicker would go away again after some days..
[HTC One X] barryb20:
Hi

Thing is I got the update around the 22nd of May so plenty time for any "calibration".

My battery dropped below 50% and I am seeing flickering in sms again and this app tapatalk.

I'm well out my 28 day return for a swap out so that may mean sending for a repair. Not ideal and slightly frustrating.

Barry

*update* whilst charging screen is OK, seems to be fine until battery gets down to under 50%, send for repair or wait for HTC to update my now (imo) faulty handset?
[HTC One X] bigoliver:
If u send it back you'll be without it for a week or two. I'd wait and hope a little longer. If no improvement send back when most convenient.
[HTC One X] barryb20:
Thanks for the replies guys.

Yeah that's what I'm thinking, don't really want to be without a phone for a week or two :-\
[HTC One X] airognol:
I'm running LeeDroid which is based off the 1.29 update and on low brightness the flicker is still there. Hopefully it improves, but now I'm seeing something I haven't before.

My screen looks like its glitching, I've only seen the issue on my Tumblr app and wanted to know if this is hardware or software based. I've attached a picture for more info.
[HTC One X] :
Carphone Wearhouse are recalling the phone now lol. There are hardware faults with the phone, and for some reason, HTC are still denying it and calling it a Software issue. Even after the update, there are still many phones with same problems, and new problems. It's good they are trying and all, but they should just recall all the phones and revise the model. No doubt they will revise the model soon though, and release it under a new name.
[HTC One X] exCluSive1:
Use latest stock kernel guys, trust me it works
[HTC One X] m2geek:
Just been sent here after derping and not searching properly...

My phone only does is when the battery is Under 50% and only when the brightness is set high/higher than 40%.

I SO hope its just a software thing, I sold my laptop to get my phone and I can't bare being without it :-\
[HTC One X] fridaycider:
flicker

my one x seems to have backlight flicker on web pages and white backgrounds when scrolling whatever i do it is still there.

running latest update and kernel

will this be a hardware problem or shall i wait for another update.

thanks
[HTC One X] sleet77:
I have the same issue.
[HTC One X] fridaycider:
small chat with htc

Please wait while we find an agent to assist you...

You have been connected to Nicola.

steven : hi nicola

Nicola: Hi steven, thank you for contacting HTC Support, I am looking in to your query now.

Nicola: can you check the following ;

settings > developer options > Dont keep activities

Please check if the same fault occurs with this ticked / unticked

steven : ok just going to check.

Nicola: ok

steven : the phone keeps reloading sense at the moment

Nicola: did you untick the box in dont keep activities ?

steven : its settled down now. it was unticked but i ticked it and the screen flicker is better but now when i hit the home button it keeps reloading sense

Nicola: Have you checked for any updates in settings - about phone - System software updates ?

steven : do i need to untick it again

steven : yes i have checked for updates and there isnt any

steven : my version is 1.29.401.11

Nicola: I would untick it again to get sense to stop reloading as this is a bigger problem for you I would have though. The next step would be for me to suggest a factory reset and then I would escalate the problem if you wish me to .

steven : i have tried a factory reset twice. i have been told that i should wait for another software update to resolve this issue.

Nicola: I would have to agreee with that advice at the moment, an escalation will probably lead to another OTA fix anyway.

steven : i hope you dont mind me asking but i have read that there has been a recall on the one x. or is it just a rumor floating about.

Nicola: Its a rumour, no I dont mind you asking, but its not official.

steven : ok thanks also do you know if there is another ota update coming soon as i am concerned about this fault being hardware not software.

Nicola: We really, honestly do not know until it is ready to be rolled out, so I cant answer that for you. HTC have given no announcements as yet.

steven : ok thank you for your time. i will wait to see what happens regarding the next update and see if it cures it. if not i will probably escalate the problem then.

Nicola: I will be happy to help yopu with that, nice talking to you.

Nicola: Is there anything else I can help you with today?

steven : no thank you.

Nicola: Thanks for chatting with me today, steven. To end our conversation, please click End Session. You’ll be invited to take a short survey which I’d be grateful if you took a moment to complete. Enjoy the rest of your day!

My hox was perfect and showed no tendency to flicker before update, 2 weeks after update phone starts flicker when battery-level is under 50%. :confused:
[HTC One X] farnsbarns:
Update 14 june

So where are with with this. I have seen little to no improvement and have today asked HTC for more info. I am reading that some who did not have flicker now have. I am not reading from anyone that it is fixed but people might just not be saying so.

Let's hear from some if you what your experience is.

Thanks
[HTC One X] hamdir:
a major update on the way bro
[HTC One X] kingp:
I've had the flicker issue from day one and it hasn't got any better with the last update.

I have a feeling that this issue is actually a Hardware issue rather than the software issue they have been suggesting. :confused:
[HTC One X] Robpollard:
I'm on arhd 6.1.0 with stock kernel and my flicker is gone.
[HTC One X] michael_or:
flicker gone

My onex developed the flicker issue after about a week of use, It started getting really bad after about another week. I was nearly ready to take it back.

I got an OTA update to 1.29 from Optus Australia, Flicker is now gone.

It took a few reboots after the update to "kick in" but my phone is now perfect.

So, software not hardware as far as im concerned.

Michael
[HTC One X] gyako:
I had the gray flickering. One week after installing update 1.29.401.11 and it's gone.
[HTC One X] deception_:
Same here! I was disappointed 11.29.401.11 didn't do anything initially when i installed it, but around 2-3 days later it's gone!

Note that my flicker was actually very bad and that it says gone after flashing different roms/boot.img.
[HTC One X] exCluSive1:
Strange stuff, but I'm 100% sure it's not the 1.29.401.11 base/ROM that solves the issue, but it's the kernel they delivered with it. Since the kernel source is still not published our devs here can't implement it in their own kernels / ROMS. I tried a lot of different combinations and the latest stock kernel fixed everything in a few hours!
[HTC One X] anubis1980:
My white one is still flickering no where near as bad as it was before the latest update. Been 2 weeks and still it flickers (didnt do this before the 1.29 update though so i dont think its a hardware fault as such)

Is there a way to fix this does anyone know?
[HTC One X] exCluSive1:
Flash new stock kernel again
[HTC One X] Foggy79:
1.29 since it came out, but still flickering.
[HTC One X] nikzDHD:
Got no flickering issues on the next base. Base 2 which is 4.0.4 not noticed any flickering as well with its kernel. It's a test release so not sure when it'll come out using it via Football's rom.
[HTC One X] huanyu:
i have flickering only on the lowest brightness (30), it is gone if i set the brightness higher. I decide to make some tweaking to the kernel to allow user-space control via sysfs (/sys/nv/nv_panel/bl_offset).

for example, increase brightness by 2

echo 2 > /sys/nv/nv_panel/bl_offset

This mean if android sets the brightness 30, it becomes 32. Then a look up table is used to set the pwm value.

Please note this is a workaround until HTC release a kernel with proper fix.

This is the lookup table for pwm output

Before 1.29 I had faultless HOX 100% no flickering. After update I'm getting pretty huge flicker in lowest brightness setting.

That sucks.
[HTC One X] pewpewbangbang:
My flicker is completely gone and fixed. Has been for a while since update
[HTC One X] Harnec:
my flickering is completely gone after the update, and I am sure I am not imagining things. ( I mean screen flickering on grayish colors, especially on high brightness settings. I didn't and don't have any other type of flickering)

I checked the screen very carefully many times because I couldn't believe in screen adjusting thing at first place.
[HTC One X] aLcHy09:
Post update to 1.29 : Noticed severe flickering just the same as most of them here..... Sent a mail to HTC Support regarding the same and they said to try and reset the phone and then get back... After I reset my phone, and turned off the fast boot and the three finger gesture crap, I am having lesser flicker but still it is visible at low brightness very clearly...

Is it something to do with the brightness control??? I think it is more of a software issue rather than a hardware issue!!

---------- Post added at 01:14 PM ---------- Previous post was at 01:12 PM ----------

And also I think most people here are referring to the absurd screen turn off and on type flickering, when they are saying that they do not experience it... That was solved in the 1.29 release and it has been confirmed by millions.

But this auto brightness adjustment flickering is still there!!!!

Thread cleaned.

Watch the attitude guys. If you have nothing to contribute to the thread you can just not post...

I had no flicker until I updated to the latest base and now I have.. very annoying
