Dead/Bright pixels problem?

Hi guys.
I'm interested to know whether Hero sets from overseas are experiencing this problem. apparently, users who bought it in Singapore (where i live) have this problem, and it's pretty widespread.
just curious to see if the problem is limited to Singapore or it affects other territories as well

Hi. I have T-mobile G2 in UK and I also have dead Pixels. As Fact I know people have this problem and It's not rare. I didn't send it back cos I Can live with it but i know people who sent it few times and still have received with dead pixels. Sad but its true.

i got 1 tiny little bright one.
annoying at first but i forgot about it after a couple of days. theres more important things in life to worry about. besides, most bright pixels right themselves after a few days/months...

i'd live with one or two dead pixels myself, but people have reported up to 8 dead/bright pixels, so it's kinda worrying

I do have around 8-10 dead? pixels but you can't notice them. One of them is bright enough to notice on black backgrounds and menus, but you hardly notice the other ones.
It's kind of weird though, they all appeared after 1-2 days of usage.

I have 1 bright pixel after 2 weeks using. The shop don't change the device with one dead pixel. Sad. In Hungary/Europe.

2 bright spots here. they are really tiny tho and i only ever notice it while booting which is not that often. no dead/stuck pixels on my hero *yay*

stuck = bright
sounds like someone needs to create an app for Android, like the apps to fix bright pixels on normal computer monitors, where u select the region on the monitor where the bright pixel is and the app constanly flashes different colors...sometimes rectifies bright pixels after a couple of hours.

i believe some of the bright pixels might well be enclosed dust ...

i have to say that i don't have ONE dead pixel on my screen. It's really great. My past device (xda orbit 2) also had another problem: dust gathering beneath the display. i don't have any issues with the build quality with my htc hero and i'm really picky too.
it's an unbranded german white HTC Hero.

If it was dust though, wouldn't we notice an increasing number of bright pixels as the days pass?

i haven't looked into this myself ... just quoting other people here.
the people in the other thread seem to have come to the conclusion it is dust enclosed in the assembly process. the seal around the displey seems to be quite good ... so no new specks of dust over time

Me too, I have 8 - 10 dead pixels but it hardly to notice them! you will notice them when boot the device.
Regards

i am not sure if mine is considered dead pixels but when the device boots up, the upper right side seems to be brighter than the rest of the screen (light shining out more from there)
however, once the device is booted up, it is no longer noticeable, maybe becoz the screen is not totally black. the only way thus far i can replicate this is to shutdown and boot it up.
does anyone have this issue?

Yeah, I also got the brighter screen in the upper part of it during boot, I think it is because of the backlight to the device so I don't think it's you really need to worry about.
But concerning the topic, I also experience dead/bright pixels during the boot up, around 3-4. I didn't even notice them during boot before I saw this thread and decided to take a closer look, not that a huge problem for me as i can only see them during the boot, and neither got I the patience to wait for it when it is at service.

first day with my hero from orange france and 1 dead black pixell !! RRRRRR

GS3: Viewing Angles and bluish tint

Hi everyone. After GS1, GS2 I've bought GS3.
Really disappointed for the viewing angles (on whites/grays), the worst I've aver found in amoled/ips lcd recently.
As I tilt the screen 15-20 degrees (normal use movement exspecially when you write/use it with one hand) during mail, web, whatsapp all the whites begin to show a sort of polarized/light blue reflection that seems to be caused by Gorilla Glass/amoled interaction. Very very annoying and tiring for my eyes, and of course not beautiful to see on a 600€ 4,8" display.
On Italian forums I have to say 90% of users experienced this, but maybe in my GS3 this effect is more prominent, difficult to say, I cannot compare by now.
I'd like to have feedbacks from you, don't know if return it and buy a new one.
Cheers.

Im swapping mine in store for the same reason.

Hi.
Is the new one replaced better?

I never understood why viewing angles were a problem. You're using your phone wrong if you need to view it at a 20 degree plus angle.

Never had viewing angle issues with past phones. Never.
With this GS3 simply cannot move it, or I have a blu reflection.
Just want to know if it's just mine.

It's the same with all amoleds ...but I don't think it affects the usage that much and it's only noticeable on plain white backgrounds ...

Haven't been to swap it yet. Im going tomorrow i'll let you know. Been having call issues were it sounds like I've gone under water about 1 min into some calls.
My mate works in a phone shop and said he swapped 3 sgs 3 for call issues today alone

Thank you nik

I have exactly the same thing on the lower part of the screen. The grey's temperature is "colder" than the rest of the screen. If you test the screen with "*#0*#" with the three diff colours is fine, the "issue" is only with white and grey background.

I see but the thing is i had sgs1, two sgs 2 ( white and black), two galaxy nexus (white and black), all of them had a blue tint when viewed at an angle .... Though I also know many have said that they don't have tint but I never got any galaxy without tint just my luck I suppose... Htc one x slcd2 doesnt have that issue but battery life is too poor on it that's why got sgs3...sgs3 is superb in every way..

This sound quality issue sounds very much like a problem described in other threads.
Perhaps you have already seen this, but if not, be aware that the problem has been solved by the majority of people simply by switching OFF the "noise reduction" feature under "Call Settings" (it's set ON be default)

Thanks for the reply but I had seen the other threads and switched off noise cancellation but still suffered from the "underwater" problem
Thanks

Sorry for the delay
Sorry for the delay in replying to this thread. I have just got back from the Carphone Warehouse where I checked four different Pebble Blue S3's...guess what.....They all had a Purple tint to them.
When They where first booted up they looked "OK" but when I turned the brightness all the way up and open a white webpage like google you could see a purple hue/tint to the screen but it looked fine when you look at it straight on,
I only have another 4 day before I can exchange mine for a new phone, seriously considering getting a HOX instead at this point. Or failing that sitting in a Samsung Service centre until I find one that doesn't have this awful tint.
I'll keep posting on this thread if I manage to find ones without the tint but I've got a feeling that the CPW UK has got a bad batch in at the moment.

My screen seems okay in regards to tint overall but the top 20% of the screen or so is bluer othan the rest and it gets gradually worse as you get to the top edge. At first it didn't bother me so much but now it's starting to get annoying =(

White Line 'flashes' on N7 Screen

Hi,
Every now and again, in either game or browsing with Chrome, a white line flashes across the full width of the screen, doesn't happen very often but would you say this is a software or screen issue?
I also have a couple of pixels in the bottom left which I can only assume is dead pixels, but they only are visible when the background is black, so are they dead pixels or stuck pixels? I've tried one of those apps that supposedly fix the stuck pixels but they are still there.
Any thoughts?
Thanks

The flickering SHOULD be fixed in a firmware update. Regarding dead pixels, you should return it.

Vsync isue?
I'm really curious what this is... it was described well in the general section by markfid like this:
I've also been seeing some issues with the screen, not sure how to explain them but it's like screen taring, that you see in games or like an old CRT monitor when it get's degaussed. It's a line from one side of the screen all the way over to the other side (Held in portrait, from left to right) for a fraction of a second. Very quick but when reading a book on a white background noticeable. At first I thought it was just my eyes getting tired, but it has happened 10 or 15 times so far (with ~5 hours of use).

I've seen that same screen tearing issue! I thought I was crazy because I've only seen it like 4 times, I think always on white screens. It happens really fast and is almost unnoticeable. I'm not sure whether it's a hardware issue or a software issue with the vertical sync in jelly bean

All quotes are from the screen separation "fix" thread.
I'm seeing the same thing.. like when you overclock a gpu or like the vsync is off or something. I's gotta last 1/10th of a second, and on irc user "speechles" says he sees it most when scrolling text and the gpu can't keep up.
Anyway, you're not going insane. I see it too.

Thanks, glad to see I'm not the only one... So going by the fact this is affecting a number of devices it might be a hardware issue?
I'm not sure about the pixels, there's probably 4-5 in a line and they go from dark to light from the top to bottom, basically a gradient but like I said they are only visible with a black screen... Might ring Google and see what they say, not sure if it's worth sending back...

I'm pretty sure I have what the OP first described too, but only when music is playing (either through speaker or headphone jack).
I already started the return process, but I'd like to know if this is software or a bad screen. I tried doing a factory reset, but the issue persists.
Maybe there's still hope for a software update.
I wonder if this issue is present in other roms.

I sure hope you're right. Seems like a relatively few amount of people have this line flashing/screen tearing problem compared to the number of people that are just experiencing flickering at low brightness.

[Q] Strange vertical lines on brand new device

Hi guys.
Just recieved my brand new Nexus 4. Haven't rooted anything yet but I can notice some strange vertical "lines" of no colour. You can just say they are present and they give some weird discoloration, seen especially in the Settings menu,
Also noticed that my Antutu 3.0 closed itself (dunno why... it's 2GB of RAM...) only once and after one of several Antutu benchmarks there were some red lines... rectangles or some other stuff moving across the screen while in multitasking menu.
Now I'm a bit worried aboy the lines especially. Does it mean that I've just got a faulty device
Please check your Nexus 4's: just set the brightness to maximum and go to the Settings menu. If you see such not moving vertical lines (they are slight but still enough noticeable to see!) please report.
I live in Poland and I really would not want to RMA it since I would have to send it back to US...
EDIT: To add, the lines are especially seen on grey background, if it matters. But I can barely see them on my main screen too... I've also thought about the protective foil which is still present on both the front and back of my Nexus, but I don't think it may be causing it...

That's almost a description of the digitizer grid. Normally if it's at all visible it would require direct sunlight at specific angles. It would appear as metallic dots in vertical lines that reflect the sunlight. Perhaps the digitizer got bonded to the glass incorrectly? Give it a few days and see, it's well known that some bonding issues stabilize after a short while. If it's still very noticeable and bothers you, RMA the phone.

I'm almost sure it's not digitizer. I've seen it a few times on my dad's Xperia Neo V, and it just looks totally different. Also, I really can't see any dots. The thing that bothers me is the lines seem to be standing in their place all the time... I haven't seen this yet on any phone,
But, as you said, I'm giving it a few days. Also, I'll compare the screens when my 2nd Nexus arrives, so I'll find out if it's an issue or is it just normal (if it really CAN be normal...).

not in any particular order. factory reset it. get z-device test from the play store and run a test on the screen. dont run benchmarks on this phone. many people are having issues. and dont overclock. people are bricking their phones. i think they overheat.

Shouldn't be anything to worry about

Anyone got these lines or am I the only one to worry about them... :/ ?

Are you able to get a picture for us to see and compare?
I have lines, more like dots when angling the phone. They look like solar panel reflection, as a description. Only visible under strong sun light.
I also see rectangle impressions at certain angles;
-CC

Here it is.
They're a little less noticeable in reality (I wanted to show them clearly), but they are. It becomes really annoying especially on one-colour backgrounds (greys!) and when swiping screens from one side to another.
Maybe it will cure itself? I really wouldn't like to do an RMA since, as I already mentioned, I live in Poland, and it would be pain to send it back to US and wait another months for new one (likely with some issues too...).
Please report whether you've got these.
PS. I also see those rectangles, but only at a very specific angle, and these are really not noticeable at all. All that bothers me are these lines...

I also get these lines when I turn the brightness up high

So I guess I'm not alone with this (issue?). If anyone spots the lines please report. It's really important to me as I'll be living with this device for probably a year or so and I really don't want to know that my phone is defective...
It's so sad; except lines, the phone is absolutely perfect; no overheating, no earphone buzz (at least not noticeable during calls at all), no yellow screen spots, no flickering, decent battery life... And now this.
Crap. Maybe that's just another "Nexus 4 feature" ?

Got my 2nd Nexus today and it's also got that strange banding. Guess it's somehow just normal...

You're seriously whining about this?? Really?!

Not entirely. It becomes noticeable mainly in dark rooms, and I really like to browse the Web in my bed on my Nexus 4
I guess I am becoming used to it now. It starts to be less noticeable, especially outdoors where it can't be seen at all. So I'll just stick with that and probably keep the phone.

I am experiencing the exact same issue you are describing and am worried myself. I just opened up my phone today. Did you end up RMAing the device? With people claiming that this is one of the best displays out there, it seems like more people would notice this problem, especially since it is so noticeable from the settings menu.

Here's a picture of the screen banding.

Yeah same issue here guys ... Already some post about it. I'm used to see thèse now but very visible at high light and grey or setting background.

So do all nexus 4s have this issue or should we be RMAing our devices?

i have this too...
why does iPhone 5 get display from lg and dont have this issue but lg themselves do?
strangely apple can handle lg's screens better than themselves
kind of sucks...
this is one of those things that once you've seen it you cant unsee it
i also have a little bump on my aluminum bezel you cant see it but everytime i scroll on the left side on the screen i feel it...

So I guess the majority of Nexus 4 devices have that, but bany users can just not be aware of this issue.
That kinda sucks, but for this price... it's totally acceptable for me

Just like to say that I also have them, they are more visible at higher brightness.

Clarity/resolution

The Xiaomi Mi 9 SE has a crazy crisp display. Just kidding, this is automated text so who knows if this screen is any good. So, you be the judge! A higher rating indicates that it's extremely sharp and clear, and that you cannot see pixels with your naked eye.
Then, drop a comment if you have anything to add!

This is the first time I use a phone that has Amoled screen. I heard about color shifting which happens to Amoled screen but I still curious. Does color shifting happen to your devices ?
For mine, when I tilt the phone, even a little bit, I see the blocks of color turn from blue (cool) to pink (warm) and backward. This only happens on white background. If the view angle is 90 degree, its fine. But if it greater or smaller than that, about 60 degree, it's just like a rainbow is moving. Kind of annoying

Please post some pictures of the display at different viewing angles.
Ive been using OLED screens for the last couple of years, mostly from Samsung, as is the one on the Mi 9 SE. They have never had any issue of the sort. I have however seen such a thing on the panels used in Blackberry phones.
The SE seems like the only device out this year that ticks my boxes as far as size and display quality, i would dearly like to know if sammy is delivering sub par screens here.
I have to say i am skeptical, so some proof would be appreciated.

Interesting. I've never used a phone with an amoled screen, but sounds like this would put me off.
Not sure if any stores here in the UK have the mi9se that I could try out before purchasing.
Pocophone I've just bought is lovely, but just a little too big for me coming from a mi6,which is why I'm considering the mi9 se.
No headphone socket though.!

Lets see if its actually true first. Here is a very detailed review that includes many angles on the display, none show any color shifting:

Honestly I'm not seeing a big problem there... But the resolution isn't great. Someone below said the A50 display at the store was better but it too has an original Sammy screen, also manufactures in Vietnam.
Mb a good quality photo?
Also, what about the issue with the notifications? Ant solution for it other than AOD?

1 month used and I think I get use to it. Maybe after I checked Mi 8, it also has the same issue. So I guess this is actually not an issue anymore
I also hope for solution replacing notification light. Heard alot about "the dot" but after many attemps with many apps, the choosen one is still missing I guess.

I have a Pixel 3. The Mi 9 SE, despite technically having a lower PPI value, is noticeably sharper. I imagine this is because it's not using the Pentile layout that the Pixel 3 screen has.
