I just noticed some today. I've got 1 (maybe 2) black dead pixels and stuck red subpixel.
Should I send it back, or just ignore it? I've had it since Friday, so they're clearly not that obvious (or maybe I just got them, who knows).
Anybody else have a similar experience? Any tips for getting rid of them if they're just stuck and not dead?
Dead pixels for phones are usually instant replace, no questions asked, if under warranty. There should be an app for stuck pixels where it flashes different colours on the screen in order to "unstick" the pixels.
Depends on how bad it is. At this high a resolution on such a small screen it probably isnt very noticeable. But then again once you notice it might be an eyesore and worth taking back.

I personally go crazy over dead pixels. I'd return it.
Oh wait now that you mention it. Nope its perfect. Replace it

Well, now that I have noticed it it's a bit of a pain, but you're correct in saying (whoever it was) that it's not that much of an issue because it's such a high resolution.
The bright pixels are more annoying than the dead ones, but the question is, would it be possible to get it repaired in Australia, even though I bought the phone from Handtec in England? I really don't want to wait for it to be back and then come over here again.

I'd say it's doubtful they would allow you to replace it in Australia. It's Samsung after all and since importing it you have no warranty in your country. You should have warranty in the UK for it though.

Actually, no. In many countries (and this might also be warranty-dependant), dead pixels do not lead to successful warranty replacement. I work in an IT company that also deals with hardware for a lot of clients and this question has been raised in the past and we have been unable to send a monitor with less than three dead pixels back under warranty.
Might be different with a mobile handset, but with a Samsung's SyncMaster monitor it was not replaced under warranty.
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.
Sent from my Legend using xda app-developers app
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.

Not all of the first batch flickered. Stop exaggerating.
Just to give you a brief rundown of everything that's happened..
I'm 17 and saved up for a few months to buy a HTC One X. Needless to say, it's probably the most expensive phone i've ever owned, since all my other phones were hand-me-downs and old phones from eBay.
This morning i wake up and go to work as usual. Just to find my phone's display won't switch on. As you can imagine, I'm tirelessly panicking and try the 3 button combo.. to no avail.
Using Fastboot to reboot didn't work either.
This phone turned into a brick overnight, and i have no idea what happened??
Just before i left for work, i did check my phone and it was working alright.. Then five minutes later, it won't display anything.
The thing is, I can't take it back to HTC either because this is my 5th replacement phone!
First one had black glue smudged on the LCD it's self,
Second one had the screen not glued down and wasn't aligned,
Third one didn't even have any glue applied and the case wasn't even attached properly,
Forth one had this problem where the screen's LCD would dilate if i touched it - even lightly,
and this one is my 5th, the antenna wasn't properly connected and now the screen doesn't work.
I've had terrible luck, and i don't know what i can do?
If you can give me any information to get me out of this, it would be much appreciated.
Although i still can receive text's and calls fine, it's just the display..
Since you’re unlocked and running a non-stock kernel and ROM, maybe some of the dev-ish folks can help you resuscitate it if it’s indeed a s/w problem.
If it’s a h/w problem, what to do depends on where you bought the phone and how old it is. If it’s within the remorse/DOA period maybe you can exchange it. It’ll be hard for whoever you bought it from to see you’ve unlocked it if nothing’s showing on the display.
If it’s outside of the exchange period you’ll have to send it in for repair. If you can’t bring it back to life to flash it back to stock you’ll have to throw yourself on the mercy of HTC Asia in getting it fixed unlocked. HTC's different repair centers seem to all have different policies related to warranty coverage for h/w faults on unlocked phones. If it is a dead display maybe you’ll get lucky.
You might want to put a note in with it telling your “I’m 17” story and how devastated you are something you’ve worked so hard for has failed. Repair techs are people too. Good luck.

I shook the device out of frustration.. and it started working for a few seconds.
What's going on here? Is it a faulty display/connection? Is there a way to possibly just send it to a nearby phone shop and get it fixed?
Sorry about all the questions, I'm shocked, happy, and devastated all at the same time.
Are HTC refusing then? That seems a bit off/ illegal... Surely under the faulty goods act (I assume the law isn't THAT different in Australia to UK) they have to take it back as it CAN'T be a year old and they can't prove the issue was caused by your mistreatment. It doesn't matter how many phones you've had... Also, where did you buy the phone from? I think you should be able to return it through the shop as THEY sold you the phone, not HTC... They are still under an obligation as they sold you the thing.
Plus, the 'I'm a 17 year old and saved up for ages thing' might work too! I'd try not to get too technical with the law if you go down this route though!
Best of luck sorting this out. It's within your rights to get a replacement (you bought the phone new, I assume?) so I'm sure this will eventually work out. Don't give up! You just need to speak/ write to the right person...

What rom were you on?
I remember my One X not charging at all while it was turned off completely although it showed Orange charging led.
It could be that you ran out of battery and phone not turning on. Due to no charging effect.
@Op,
Reading your story there's one thing that's crossing my mind.
Could it be possible the battery run dry during the night?
It sounds stupid but those things you forget easy when you're in a hurry or stressed.
I don't read anything in your post you tried to charge.

Yes. But not in every region (yet). Do a search. It's been disucssed. Also, it appears Samsung's going down the same path.

Aware of the discussion... Using the xda app and didn't pick up that the phone's been 'HTCdev'd (my fault for not reading properly - sorry, folks!). Still not sure HTC/ Samsung can legally 'sign your rights away' though. Still, not a discussion for here...
Hope you got the phone sorted anyway.

How or who fixed ur antenna problem, could be related if handset wasnt but back together properly.
After flashing the stock google (yukju) roms on my galaxy nexus, everything went fine for a couple of months and now I am getting weird haywire issues with my touch screen. Without me touching anything, the phone will act like a part of my screen is being touched, it will not respond when I am indeed touching it at times, the screen will flicker back and forth and generally act strangely. Then for the other 70% of the time it is fine. I have re-flashed all stock roms, did a factory reset, and the problem persists.
Is anyone else having these problems?
any idea what to do next.
After contacting my provider, they said they cant help me because I had unlocked the phone. I have since relocked the phone so I might try calling back and seeing if it will fool them, but I doubt it. Now that I have re-locked the phone should I try to deal with Samsung?
Any help appreciated!
It sounds like a hardware issue. Most likely the touchscreen itself is bad. If you still have warranty or insurance coverage then bring it back to the store and tell them it is defective. By the way, NEVER mention that you have ever unlocked or rooted your phone.

Thanks for the reply. Im worried that, like you say, it is a hardware issue because I bought it used, and therefore will probably have problems with warranty/insurance. My carrier has already said that they wont help me with it so I would have to go right to Samsung. Any tips on dealing with Samsung? I have already returned to stock and re-lock the phone and I never rooted it, I certainly wont say I did anything to it in any way. Anything else I should be aware of? Will they even help me out since I wasn't the one who bought the phone in the first place?

Although most manufacturers offer a 1 year warranty on hardware, I doubt they will honor it since you were not the original owner. Your next option is repairing it yourself. It took a look at prices on eBay and it looks like the digitizer (touchscreen) for a galaxy nexus goes for about $30 and the combination of digitizer and LCD screen go for about $150. I don't know how difficult it would be to separate the digitizer from the LCD on your phone, but $150 for the set is still better than buying a new phone.

As has been said, it is probably a hardware issue - I had an HTC Desire S before my GNex and had the same issue with it, started all of a sudden. (The screen would go haywire as you said, almost as if a ghost was pushing buttons quickly - that's the best way I can describe it). Mine did not have warranty coverage because I had rooted and unlocked it but the HTC rep was helpful and said it happens sometimes because of moisture or humidity or some such thing and to replace the lcd/digitizer. Cost me a little ($110) but phone was as good as new after that, used it for six months before selling it and buying the GNex.
TL;DR. Nexus 5x on Verizon has no cellular service after screen replacement. I changed my baseband to USA Base (a mistake?) and also did a factory 7.0 flash but still no service. Suggestions??
-----------
Hi all, thanks in advance for the help. I replaced my screen/digitizer on my Nexus 5x. I'm on Verizon. When finished, everything worked except I wasn't getting cellular service. It actually said Verizon but I wasn't able to make calls or use data (I did have one text message sneak through which was strange). Eventually I made my way to *#*#7636#*#* and changed my baseband to USA Base and since that the phone doesn't recognize verizon at all.
I've already tried flashing the google stock 7.0 image but that didn't work. I can't find any loose antenna wires like was a common problem on the Nexus 5, although I don't know exactly where to look either. Any suggestions? Thanks!
Only way to change back baseband is unlock device and install ROM which supports it, there is modified pure nexus rom, search on google.
Here is modified ROM https://mega.nz/#!UhZjHToL!qdIA_HybUdzBlSDjRO1Y7_4byl7w0wPlCw5dsLbwIDg
I think you also need appropriate vendor.
This known issue since device launch and there is no fix from Google, they just replaced device if you bought it from Google play store.
Thanks fanta110! Can you please explain what you mean by needing a vendor?
Also, I am in the US, so shouldn't USA Band work? From my research I could only find people living outside the US who had issues after switching to USA Band .
Update: I've managed to change the baseband back to "Automatic." Now, I get a some service but it's very bad. The sim card is being read, but the phone now spends most of the time on extended network or Verizon with zero bars. If I go to an area with really strong coverage I may get a few bars of LTE.
It's like I'm blocking the antenna or something. Any ideas? Again, this happened after a screen/digitizer/mid frame replacement.
Thanks!
I learned with my note 2 waaaay back to not ever get a screen replacement. It's a gamble. I had a very well known company do mine in Houston back then and it was never the same. Pissed me OFF!! Hope you have better luck.

Well yeah, it's a gamble of $400 for a new one phone, $200 for a used one that may or may not work perfectly, or $50 for a replacement screen that may break something else. If I fix this issue, then I saved quite a bit of money! It was actually super easy to do and I simply think that either (1) I just need to have Verizon re-activate my phone or something like that or (2) I mucked things up by slightly damaging the metal sim card container when prying the battery out (in which case it was completely my fault for not getting the right tool - I was lazy and just had an over-sized screwdriver by me).
Come to think of it, is there any reason why (very slightly) denting the metal sim card holder might cause cellular connection issues? I don't see how since I don't think there are any antennas there (except for the wifi 2x2 MIMO SoC on the other side of it), but I'm certainly no expert. Again, my sim card IS being read, and I'm sometimes getting service - it's just terrible and often no service.
I have the exact same problem. My screen was replaced and now my reception is terrible, especially inside buildings. When walking outside is pretty good, but as soon as I take a few steps inside the house or even vehicles the reception drops to a few bars or "no network available" at all.
There seems to be no solution to this as far as I know. Maybe replacing the antenna, but I don't even know if that's physical possible.

Jeez, for a long time there I thought I was the only person who had this issue! Unfortunately, I haven't found a solution yet. I definitely have a ~25dBA drop in cellular signal, though. That signal stays when the back cover is completely removed as well as the motherboard cover, so it's not that I knocked something loose on that side. I also pulled up each spring contact to ensure good contact but no go there either. My best guess is that the stock digitizer/screen/frame has some sort of booster in it somewhere that didn't come with my replacement.
Did you replace just the glass, the glass + digitizer, or the glass+digitizer+mid frame?

I'm almost afraid to say, but I had it replaced by a store. I'm an extreme n00b when it comes to engineering...
Anyway, I think they probably only replaced the glass. They told me it was a pain in the ass to order the glass anyway. 5X parts seem to be quite rare.

Hmm, they probably replaced all three or maybe just the screen and digitizer. If you ask the shop what the deal is and learn anything new, please let me know! My Nexus 5x is currently retired.
Maybe the cheap screens are missing something, theres a seller on ebay that has them for like 120 and claims there official lg. The same ones used in lg service center. There must be something crucial missing in the knock offs! Just google oem displays and its the most expensive. I guess you get what you pay for

Retired altogether eh? May I ask what phone you're currently using? I was thinking about replacements, but I can't really find anything in the same category. Maybe the Oneplus 3 but it's quite expensive.

It may still be worth asking; they may know what to do. Well I'm using my backup phone for the time being (Droid Maxx) until I figure out what to do.

The screen is the most common part you can buy, and there shouldn't be a problem to find one. You can use something like this, I'm currently using one and the network signal works ok.
Or, if you want the original one, probably you can find a cheap (same price or less than the previous one, <20$) 2nd hand bootlooped N5X phone in eBay. Either way, it's weird the poor coverage 'cos there's no antenna cable inside the phone. Could it be that they have installed a poor quality screen? Could it be that they have installed a non-original back cover or without the original parts (see image)? Could it be that they have installed a loose back cover and any of the connectors doesn't make a good contact?
The screen replacement is very easy in this phone, anybody can do it with basic tools: https://www.ifixit.com/Teardown/Nexus+5X+Teardown/51318
Thank you for replying, but I had no idea this thread was still open. By now I haven't used the phone for a while. I updated to the oneplus 6, dropped that and the screen stopped working so now I'm using a cheap backup phone until I've got some money to replace my oneplus 6
