Screen Flicker - Response from HTC

I have had my One X since last week on O2, I have noticed the screen flicker on full brightness. So I decided to contact HTC about this and they told me that there must be a problem with my device and to send it back to O2 and get a new one.
If that true then the new 1.28 OTA will not fix the problems that we myte have and it’s a hardware fault 

What do you class as a flicker? I notice my screen dimming and brightening fairly regularly under artificial light. Is your flickering more regularly?

Its more like a light strobe effect

You are right. Go and return it for a new one... HTC told me the same!

I'm the same.
Had an undranded One X from phones for you with terrible screen flicker.
I phoned HTC and they said it was def not normal or something that could be fixed with a software update.
I'm just back from exchanging it for a new one and this one is flicker free.

seems there are different types of screen flickers...
i experienced once something like a bad analog tv reception on a very small rectangular portion in the upper left corner when using the browser. you couldn't figure out what was "underneath" it.
it disappeared the same way it appeared...out of the blue

Hi, guys. What do you mean by screen flicker? Im finding that with mine on full brightness it appears as if the backlight part is flickering. Is this what you guys have had? thanks

When you say screen flicker is this happening all the time? I mean are you talking on the home screen and in apps or just when things are loading etc...?

this is not a flicker this one is the browser glitch
silly game HTC is making us play really....more n more i realize i was stupid not to keep the grey that was running perfectly

I just can't see how it can be hardware...
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...

it's what is being discussed here http://forum.xda-developers.com/showthread.php?t=1592157
and HTC CS said the same to me, do a DOA. So I don't think it's software related. Those responsible at HTC should have let their employees know by now if it was SF related, so there's no indications it is so.

Thinking back to when my MacBook had a flickering problem a few years back and when I remember a Dell laptop at work having had an issue before too; I am sure Apple/Dell simply released firmware updates to fix the problem as it was an update that had caused the problem.
Surely something similar can/will be done with the HTC? Maybe its not happening on all devices and is inconsistant so HTC are telling people to DOA there devices whilst they work on a fix for it (maybe OTA)?
I just find it hard to believe that I have had 2x devices now and both have suffered different issues that it could always be the hardware. It would have to be seriously bad luck for 2x phones to come with issues down to the hardware; usually when this many people are having problems its a software issue over hardware (isn't it?).
I mean mine is flickering slightly on certain screens or during certain actions, I don't want to DOA a second device just to get this problem again as I really do love the phone. If the flickering can/will be fixed then I am happy to wait for that, but as mentioned before at this rate everyone with be DOA'ing devices just for the sake of it as different devices just seem to have the same and/or similar issues.

I have this problem. What is weird is that if I charge the phone fully the problem disappears until discharge at reaching like 80% where it starts to appear again and gets worst over discharge. I'd like to know if I'm alone. If not there are chances an OTA can solve it as it would be some kind of bad power management of the screen. And we all know our power management has some troubles

Well I didn't notice it at all today, but I have noticed it when my device got to around 68% battery. Although it could of triggered before but I might not have been on the device. Whilst I was using it from 100% down to 86% everything was running perfectly fine with no flicker at all.
Could it be an app/widget in the background that is causing it? Then again probably not as we would all of had to install that same app/widget so ignore me there (thinking out loud).

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.

If the thoery of it appearing while battery is going down it could just be some underpowering of the screen. That sounds logical and solvable via OTA.
I don't think any app could do that

Yeah it does... As I said thinking back to Macbook/Laptop and the flicker (which had LCD screens) they were sorted via a firmware upgrade as I mentioned; which really would lead me to think OTA could sort it and that HTC are saying to DOA devices simply because they don't have a solution right at this moment in time.

Wasn't aware of this MacBook case. Nice to hear.
As I had some troubles with HTC i can tell you that (at least in France it works this way) their support service is like a different company. There is no communication between them and that is wanted for you not to be able to go far in complains. The people at these support center just read there scripts and know less of the product than we do. They can't be aware of early releases issues this way so for them the only solution is a new device. In the end that is stupid because they loose money and their good reputation

Thats exactly how it happens over here mate; would rather do the quick fix (handset exchange) than worry about the problem as they are reading from a script and probably don't even really understand the problem... By giving you another device they can simply bide time to report the problem to the technical team to work on a resolution.

I get that flicker only at lock screen when the notification lock screen its select it. Other than that none. So I can't use that lockscreen

Is your Device faulty or perfect?

I figured seeing as there a quite a few issues surrounding the ONe X, maybe we should have a poll to get a general idea how many phones are affected.
Many owners have no issues but we only hear about the faulty phones and not the fault free. and for alot of owners this puts us off the phone.

I am plagued by the wifi problem...

we already have this poll and a new thread will divide the results
http://forum.xda-developers.com/showthread.php?t=1585082
and the recent feedback about QC is a massively better than before

I got a very little "yellow" tint at the phone bottom, it looks like a very little yellow light leaking , nothing to worry about yet. so i can consider it PERFECT
If you have WiFI issues, try to go to advanced options and turn on maximum performance

I voted in that poll saying my device was fault free. I spoke too soon as I have now developed the dreaded WiFi problem. So bad infact I struggle to get a decent signal sat in the same room as my router. Written to HTC tonight about a repair/replacement. Bitterly dissappointed as I thought I got lucky with a faultless One X.

My handset doesn't recognise usb any more even though it gets recognised in fastboot and charges my phone

[HARDWARE FAULT] [BSOD] Blank Screen of Death : Information Board - Updated 29/07/12

A few users have reported a Blank Screen of Death, with myself included.
The problem being that the phone's display doesn't switch on when you wake up the device. At this time, Everything else will including the Digitizer and Capacitive buttons.
I have spoken with HTC service centers across Australia and NZ to come to the conclusion that this is a motherboard problem. The infamous flickering issue seems to be involved also, which ends up shorting out the video driver.
The issue isn't just limited to the screen not displaying anything either, there's also the possibility that the back light will cut out, and sometimes leading to corruption on the display.
This isn't just with some devices either, it seems like anyone that has had the screen flickering issue are at risk of this.
To give you an idea of how much it costs to fix this issue, I was quoted at $250 AUD for just the motherboard alone.
The best part is, HTC may also deny your warranty for unlocking your bootloader, as they have with me.
I'll be posting more information as it develops.
EDIT 29/07/12 :: I'm going to request a transcript of my last conversation with HTC but until then, they're denying that this is a problem and saying that it's the user's fault. How? We use our phones to much, or inappropriately.
It's becoming obvious that they're trying to avoid spending anymore money fixing these issues, and have decided just to move on and release a new One X model. (according to news sources.)
Also, Boobinator just posted a video of the One X's screen corrupting while it isn't stuck under the BSOD which you can see here and here
Just to recap.
When the initial issues were found with screen flickering and corruption on the display, we were told it was a software issue.
Many months later, I along with many of you are still experiencing it, even though it's not nearly as bad as it once was.
Now there are growing reports that One X's are starting to lose their displays, and the poly-carbonate weakening and bending the antenna pins. (You can find more information here)
This is something you should all be aware about when purchasing this phone.
Best of luck!

Update Bump

Maybe us in America can file a class action lawsuit? I'm no lawyer here but anyone with better understanding of American consumer laws chime in?
This is problem that occurs with normal usage of the phone.

Another day, another hardware issue. HTC is going down the drain, im hugely disappointed in the way they are handling this mess. Improper testing, too slow to fix problems or ignore/deny them. Bull**** games about unlocking and warranty and now they are already talking about releasing more phones. Its easier for them to move on to a new model than to do the right thing and do a complete recall. Is this a QC issue or a design flaw, with all the negative reports I'm thinking its the latter.
HTC better handle this properly, they need to stop development on all new products untill this is solved.

Can u please send me details about the store that sells the motherboard ?
I have the same problem...and I need my phone fixed !
Thx

Is this the same flickering that happens in some ROMs when you rotate the phone?

Mine too
This just started happening to mine Nothing displayed on the screen, but it still responds to inputs. Even rebooting into fastboot, same problem. So everything is functioning except the display.
Have just handed it back to vodafone for repair, don't like my odds with the unlocked bootloader though :/

I had this issue on Viper or Android Revolution, but not on other ROMs. But I'm starting to get wifi issue, scratches, scratches on camera lins. I should buy S3, not this.
Sent from my HTC One X using XDA Premium HD app

sent it back because of flickering. I just hope they will fix the problem properly and change the motherboard.

This happened to my Incredible S too if any one's interested.....
I'm not buying the HOX, I'm sorry. There's just too many different issues for too many people with this phone. It's an expensive top of the line phone, that does appear to be pretty shoddy put together. I don't care if it's under warranty and I have dumbass-insurance if I break it, but I can't send my phone inn all the time even if it's free. You shouldn't have to send it in at all.......
I presume now know we know why HTC is loosing money, market share and their stocks are going down....

This happened to me too, about a month ago, the phones been in repair since then(1 month, are you freaking kidding me HTC). I also unlocked the bootloader, lets see whether HTC charges me or not.
Also, I managed to get the display to work(somewhat) after shaking the device a bit. But even after that the display wont work properly, I even have 2 short videos of the screen acting weird when i got it to work. Here they are - Video 1 Video 2
Sorry for the ****ty quality, got it on my iphone. This was after I shook the device and the display magically started working. Even with the display working you can see it is really weird, even unresponsive at times.

So guys, there are a lot of places you can buy motherboards from, but they will charge you a lot more than what it's worth mainly because of the shortage within HTC.
I'm so sorry all of you are going through this, but i think we need to raise awareness of this issue. People are buying these phones without realizing there's a good chance they're going to have either bad WiFi antenna's or even a bad motherboard.
Send this to your friends, post it around, contact HTC.
Best of luck!

I am having this problem as well, as well as the WiFi antenna issue. The WiFi antenna somehow bent itself somehow, because after a while it was back to normal signal strength, so I didn't feel like sending the phone away for a month. But now with this screen issue it really is unusable, so it seems I don't have a choice anymore

Heat damage.

I doubt it's heat damage, i hardly played games on mine and it had that problem. I think the most i played was Triple Town, and that was it.
Also, wouldn't it be a massive problem if it was heat damage? That means the tegra 3 processor can't handle stress, and given that the phone inherently has heating issues, this just draws the conclusion that the Tegra 3 is bad news?

it may be a faulty soc

From what I've heard, it's been linked directly to the flickering screen problem. Which could mean that the first batch of One X's have all faulty Soc's? I mean, it's not uncommon for there to be manufacturing difficulties for the first few batches, but this is just absurd.

[Q] ONE X Battery/LCD replacement query

I recently sent my phone for repair because of abnormal overheating within the battery (which consequently caused screen burn causing a yellow tint). I am happy to be informed that HTC replaced the LCD screen panel/touch panel and the bezel as well as a new battery.
I was wondering whether the battery/lcd parts are the same as the stock parts or different tweaked to stop this problem ever occurring again. Any ideas?
P.S. Have been away from the 'development' side of the OX forums as of lately (since i have no OX and didnt want to be reminded of that), I have noticed that there are now 2 android development forums for the OX, the original and the other is just standard. Is there any difference between the 2?
Regards,

There is an announcement at the top of those forums explaining the differences. & I think HTC will just replace your screen with another normal LCD/battery. They will be newer though. Sounds like yours was an unlikely case so I doubt it will happen again.

Random ghost swipes while typing.

Am I the only one experiencing some random ghost swipes on both Asus and Google keyboard while typing fast on my Zenfone2 4GB? Don't occur consistently, just here and there but annoying overall.
It's almost the same behaviour of my previous OnePlus One, who had the 1+ possibly knows of what I'm talking about.
Didn't have the chance to record a video thou, but I will.

I would RMA. I had the same issue on OPO, absolutely terrible.

Yep. I guess you know what I'm talking about.
I ran some multi touch test and everything works flawlessly, so basically I can't reproduce the issue on purpose. But it happens. I hope the RMA process it's not a firewalk as it was with 1+.

Just a thought... D'you have swipe typing enabled?
Otherwise, it sucks you got hit with the same issue on two completely different devices. Zf2 actually rated as among the best in touch response. If your issue does persist, you probably got a lemon. =/

Yes, swipes are enabled. I use to type in both ways because some words are easier to get written with swipes especially on one hand use. I'm quite a fast typer, could be my fault, I guess. But didn't have anything like this with my previous android phones (zte blade, nexus s and nexus 4). It isn't that frequent, but it happens and after the 1+ burst I don't feel confident and comfortable anymore.

I am noticing this occasionally as well... it seems to happen in the bottom left-ish area of the screen... to this point I have assumed it to be some wild coincidence related to me accidentally touch another part of the screen while holding the phone.

I got hit with this issue on my 1+1 which is why I bought this phone as I couldnt even unlock my screen, what I noticed is once the heatwave over here hit, 1+ started having issues with typing (same as OP) and everytime it was hot it just wouldnt type correctly. I'm not expert at all but Im thinking it has something to do with the hardware and over heating as 1+ forums are filled with ppl with the same issue. I downgraded all the way back to the very first firmware and was still present.

Well with one plus was slightly different because it suffered of some serious hardware related problems, mostly connected to the bad grounding of the digitizer. There were some "triggers" that lead to an impossible typing, once you got above some thresholds of temperature or usage, the device was done and nothing could revert back.
Using Yet Another Multitouch Tester the 1+ looked totally gone wild especially when testing different touches on the same x-axis. This problem doesn't occur at all on my Zenfone2 in any condition.

Update: wrote to the CC, the guy told me that is something related to the multitouch behavior of the ASUS keyboard. So, I thought that basically it doesn't recognize two different typing so near in time and swipes instead, merging both touches in one gesture. The disappointing thing is that it does the same also when typing on a multi-touch enabled keyboard like the Google one. Still waiting for a reply to my last email where I asked what I could do furthermore to check things out.

does anybody experiencing this right now? for me it's getting heavier and CC won't do nothing about.

I had this issue on my previous phone i.e nexus 4 and after few days my touch stopped working, so it is better to visit service center and get the touch panel replaced
