I have the same thing and tried the different methods (including playing a video that is supposed to help) but nothing worked. Mine is in the corner so I have learned to live with it but it sounds like you might need to get the unit swapped out. Will be interested to hear if HTC obliges.

yeah, my single pixel shows light blue down on the lefthand corner as well. it doesn't bother me in the least.

I got my screen repaired UNDER WARRANTY! You should at least try it.
I heard awful stories how HTC refused to swap devices/screens under warranty, because of dead/stuck pixels, if there isn't like 4-6 there.
But still, at least I got my Kaiser repaired under warranty, just by calling HTC official support. Got a statement there that my provider should fix it, then took down the reference number from HTC case and called my provider, and they agreed to swap it! (gave the reference number, and told that the screen is supposed to be swapped!) I am so happy right now! *Knocking the wood*. Hope I'll really get it back after 2 weeks with no stuck pixels on it anymore.
Of course I needed to tell them at HTC that I think itäs totally unacceptable to have 1 stuck pixel on the screen. As in comparison to 19 inches screen that equals to 15 stuck pixels! Don't know if that affected the decision, or maybe the customer support technician was one of the nice kind.

I had a blue dot on left corner also, i could see only on black screen ! so ... Accidentally i found a solucion... note: in my case works ! with my finger, i just press a little bit hard on the right down corner, and the blue dot Disappeared... but when i press hard on the corner with blue dot, it came back... so, I presume that is a bad connect in same way... i order a new screen anyway, but still use the old one Without blue dot .
p.s sorry my

i have a white dot in my splash screen
and i adore it!!!!

Stuck red pixel

I have a red pixel at the bottom left corner of my One. I can only notice it on a black background but it's driving me crazy.
I wont be able to exchange my phone because I already did once.
Is there way to fix a red pixel?

You can't RMA again? It's a manufacturing defect they should be able to exchange it.

i only see a stuck pixel top corner of mine, i can careless about it.
Try those stuck pixels apps on the store. basically all it does is switch to different colors every second for 20 minutes.
It might get it unstuck, idk.

Well when I returned it the first time, I went through my service provider, and they told me that they wont be able to changed it a second time but they can sent it out for repairs. Do you think I can RMA it with HTC directly?

I tried one of the apps and ran it for about 15 min with no luck, I also trying massaging the screeen and tapping the pixel with a pen but nothing either.

Try dead pixel detect and fix for 30 mins. This fixed my 2 bright pixels. The free version is enough.

Interesting Display Problem about my Note 5

Hi dear XDA members,
I have some problem about my Note 5. I bought my phone 17 days ago. It is genuine. I was walking. And weather was sunny. I opened my phone and tried to call someone. Brightness was %100 (manual). I saw, Light Sensor worked (more Brightness). And Promixity Sensor worked too. Because, I was speaking with friend. I finished my call then I looked the screen:
What the….. Screen turned a green, purple, pink, black, gray, navy blue hue. I shocked and I got screenshot, then restarted Note 5. I check the screen when restarted. It was okay. I opened the screenshot for check it too. SS was ok too. This is my 1st problem. And i didn’t see this again.
Now, a 2nd problem in same day:
I’m using Swiftkey app with gray keyboard theme. I was chatting with friend. I called him (weather was sunny again) and turned back to keyboard.
What !? Gray keyboard turned a greenish hue. And I check my wallpaper (i was gray too). Its bottom lines turned a greenish hue too. Then I restarted phone and problem finished again.
Later, I called Customer Service Representative of Samsung. I explained all problem. She told me: “Format your phone. If problem isn’t finish, bring phone to service.”
Then, I formatted phone. Tested it many time. And there is no problem for 6-7 hours. BUT… I got the problem again. But I found some interesting tips to check the problem.
1. I checked *#0*# . And everyting is okay.
2. I opened my wallpaper in “Gallery” . And bring its top line to bottom line. So, gray was gray. But wallpaper’s bottom line was greenish on desktop. So, i think this isn’t Screen Panel problem. Looks like graphic bug. (Btw, notification bar's background was greenish too.)
3. I tried to active Light Sensor without “Calls” . And there is no problem about colors. Only in “Calls” . Looks like graphic bug with “Calls”
4. I didn’t restart my Note 5 when i got the problem again. I tried to lock off / lock on. And I saw: Screen turned to normal.
So, friends.. I think i will bring phone to service for research this problem. But I’m not sure. Problem looks like software bug. OR HARDWARE ? And maybe GPU problem ? (I didn't get problem in games, apps, etc.) I’m Confused…
Please help me. Must i go to service ? Or wait for new update etc.
P.S: My English isn’t so good i think. Thanks for understanding and helps.

Is my topic visible ? I'm new in forum.

Since this is a defect in their part, it should be covered under warranty. Just send it in, it is most likely a problem with the GPU or other component if even a format didn't fix it. If it was a software bug, the problem would be more widespread. It should be free of charge though because it isn't due to your use

Thanks for reply mate. I called customer service representative again. He told me: "If your phone is defective, we'll give you new Note 5 or you can take your money back. This is for new purchased phone (in 1 - 30 days)"
I will bring phone to service tomorrow. But I will be sad, if they tell me "it is software problem." I don't want to give my phone for nothing. But I don't have another way.
TY again.

Hi again mates !
I got the phone from service yesterday. They found nothing (very funny).
I spoke with employee :
* M = Me
* E = Employee
M: Did you open the phone's case for check the problem ?
E: No, I can't open the phone. This is risky.
M: So, How did you understand there is no problem ??
E: I think you used the phone as obsessively.
M: Wait. Did you tell me "obsession" ? I saw the problem with my eyes !
E: Mr. Cpt. Price, I mean: Don't care about it. Just use the phone. I used your phone for test. I saw nothing. You must take a video if you see problem. So, we can send it to SAMSUNG as proof.
M: You are very funny. I saw truth today. I saw Samsung's quality. Give me my phone.
So, guys I got the phone. And I'm using it with %98 brightness on a sunny day. So, there is no problem for now. I took that problem with %100 brightness on a sunny day. If i get that problem, I press lock off / on button. And problem is being finished.
I think I won't send it to service again. I won't spend my time for nothing. Sad but true: Apple is better than Samsung about satisfaction of service.
I will use the phone and if see a serious problem, i will go to service then.
I think that was a software problem or bug. What is your thought and advice ?
Regards...

Do you have any idea ?

They told me: We need to find a problem for change the phone. So, we can show proof to Samsung.
I don't know, how is Samsung services in other countries. But in my country: Samsung services are bad.

Touchscreen problem

Hello!
I've got a strange problem with my touchscreen's upper space. The notification bar can't pull down. I made a screen test under service menu, and the screenshot shows the result. I think, my guarantee expired last month, so i must made it at home. First, i try with a hairdryer heated uo top of the phone, the touch foil can push back .. unfortunately without success.
Beause the warranty has expired, eager to take apart the phone, I changed the film is already affecting other devices earlier ,. but this will be the last thing i will do. Before that, are there any "home trick" to solve that problem?
I changed so many firmwares, orfficals and customs. Problem stays the same.
Thanks for the help!

Is hardware problem. There are many threads here that discuss the issue. Only solution is to send your device to Sony repair or replace the digitizer yourself.

I had the same identical issue. First started with the screen getting random touch inputs and then the top area stopped responding. Mine is yet under warranty so sent it to Sony repair. They kept delaying it saying awaiting parts and then after chasing multiple times it was repaired and sent out last Monday. Says case and display as replaced. Yet to set it up.. contemplating between Kitkat or leave it on Marshmallow.

Yep sux, mine touchscreen was bogus too, send it in to be fixed under warranty

I have three z3c on my house two has this problem.
Is a sw trouble can't use screen protector....
Enviado desde mi hilo y dos yogures desde PetaTalk

I came on here to look for this. Happening to mine as well.
The *strange* thing is though when it's on the lock screen the swipe down works fine.
Unlock and starts being temperamental. especially in apps.
Just out warranty by about a week. Great.
I've installed Nova launcher as that lets me open notifications by double tapping the screen. This doesn't work in apps but does on the desktop. Anyone have any idea how much this costs to be repaired?

The reason it works on the lock screen is that the hitbox for the notification bar is larger on the lockscreen. I had the same issue, luckily my phone still had one week of warranty left and SONY replaced the whole phone for me within a week for free. I sent it to official SONY repair centre here in Dublin, Ireland.

Hey Guys. It happens also for me. From 1 hour to another! And actually the fist hardware probem I ever had with Smartphone. Congratz Sony!
Its clearly visible that an complete vertical area from top to bottom is not or only very sporadic accepting the finger movement.
So Service Center is the only possibility? What do you think? tried already complete stock and factory reset.
Actually its logic to send it to Service but if you have comments or maybe the same error please let me (us) know.
Thanks for any comments in advance.

Same thing is happening to mine, almost two years to the day after I bought it. I'm gonna try taking off the screen protector to see if that makes any difference, otherwise it's phone upgrade time (which is not a bad thing). Started a week ago intermittently and now is pretty much permanent. PITA.

Mine is now a week at the service center. I bought it quite late so one year guarantee left for me. Will report what they did... But it is a bit scary how many z3c went defective because of touch screen problems...

I solved the navigation bar problem using Xposed + "Xperia/AOSP NavBar Buttons" module. Just increase navbar height to 150% and it's done. For the notification, bar install Nova Launcher and use the home button action (free) or the swipe down gesture (paid).

Just to give you an final report: They changed my phone and I received an new one...
And the replacement was send right after I asked for ETA. All in all it took three weeks.
So maybe (if you phone is at repair in guarantee) asking and asking would speed up things and the possibility to get a new one is rising...
Now I have a white one (instead of black) but its OK...Feels a bit more like a new phone because of new color Thanks goodness not green or red...
The letter said that chaning to higher one or to another color is part of sonys replacement policies.

Hi again! The story continues. My guarantee expired after one year, but my warranty was good. ( it's 2 year ) I sent my phone to the service center. After two weeks, the service center changed my phone to a brand new xperia x compact.... I hope this will not be wrong with the display. In any case, I was pleasantly surprised to Sony right now.

What seems weird to me is that several people report the same problem at the same time. E.g. it start with random "clicks" on the taskbar and then the touchscreen area of the taskbar stops working. This is happening around the time of 2 years of using the phone. Really weird.
I like the phone but this is just disappointing. After the nougat update fail for the z3 / compact (first claiming that it cannot get nougat because of missing vulkan support which turns out to not being required by the compatibility definition document for nougat) and now the touchscreen fail, I'm pretty sure not going back to Sony for a phone. So sorry.

I have this problem too. The notification bar stopped working in august. And since yesterday the bottom of the screen doesn't work too, so I can't use the on-screen virtual buttons :crying:
I'm afraid this is getting worse and worse.

I've faced this problem too. I buy Nova Launcher to use it's custom swipe down gesture as notification bar issue's workaround.
And i enable Glove mode on Display settings as on-screen virtual buttons issue's workaround. Of course it does not comfy.
As a newbie, i believe this issue caused by the software/MM. Maybe i'll try to revert back to LL or KK or another rom, since z3c would not get nougat update

I can add this to the list of defects I had as well.. Send mine back under warranty about a week ago, hope i'll see it back soon.. Nova Launcher is a good option but the xposes AOSP navbar seems like a better solution, if you have exposed.

I too have this issue with top portion of screen. Any day fixes other than buying new screen (1 month out of warranty)

I've updated to the Z5C and shelved this phone. I picked it up today to check which firmware it has and alas, the touchscreen simply crapped out out of the blue. This is unacceptable. The phone jack also went bad before I switched. I'm really pissed and I don't know what to do. I bought this phone two years ago. Look at the touch draw test to see where it died. How can a touchscreen go bad out of nowhere????

Hi everyone,
I'm facing exactly same problems described in this thread.
I bought my green Z3c in Italy less than 2 years ago and I still have the invoice, but I'm wondering if the warranty is still valid.
I'm wondering because I broke my glass during a trip in Australia and I replace it there, in a store, with original Z3c LCD touchscreen and frame but black colored. (I no longer have the store LCD receipt though)
What do you think? Can I consider my device to be under warranty?
Regards.

K20 pro screen went black after 10.3.5.0 update

My K20 pro screen had gone black after the update, it booted up and showed the lock-screen for a second and then went blank. I'm not sure if this was because of the update or a h/w issue. I held down the power button but it only vibrates every 10 seconds. I was able to go to recovery and fastboot mode but both also shows blank screen. I tried flashing the 10.3.3.0 Fastboot rom through miflash, but even after restart the screen doesn't turn on. Has any one faced any similar issues? Any help/suggestions ?

I did not get any issues after this update. No idea why its happening, heard few more display blank/dead incidents. Do you still have warranty?

did they changed ur display?

Even I had some issues, it was taking painfully long to boot up after the update. But I managed to hold on with out doing anything.

No they did not. But they confirmed its a h/w issue. They have emailed someone to get the approval for a device replacement. They said they would inform me once they get the approval. Lets see, its been 3 days since i'm left with this paper weight worth INR 28k.

Depending on the service centre, you will probably get a new device. It might take a few days but from what I have seen in the past their services are good enough...
A horrific thing happen though.
Seems the Assembly line in India is like a lottery system. Either you get a good device or you get a problematic device...

Just got an update from mi service center. They said that they have got the approval to replace the device. So I can expect a new K20 pro within 2 days.

Got the phone replaced.

Hey,Bimal. I am having the exact same issues as you did, can you help me out?
Which service center did you visit and what was the procedure and did you carry the purchase invoice with you, how long did it took for them to inspect your phone?

I'm facing same problem as you were. Can you please help me out? I live in Delhi, which service center should I choose for the vest response or can you just share your experience and explain the procedure?

Should we return back the accessories as well??
