Dead pixels and washed off and less saturated display - Xiaomi Redmi Note 4 Questions & Answers

I got a note 4 back in February but i noticed some dead pixels and the display is also very less saturated and contrast is very low. I replaced it still the replacement also has that dead pixels and less saturated screen.
Since i couldn't afford to wait again for replacement i decided to get to service centre.
I wanna know will i get my display replaced without any hassle and for free?

bright pixels on display

I just bought a Viewpad 7 and noticed some bright pixels in the display. They don't look like dead pixels but like some kind of reflection. Now i'm thinking about sending it back and getting a new one but the shop told me if it was only 1-3 dead pixels they wouldn't replace it.
i can't say what it is so i'm not sure whether i should send it back or not.

[Q] Display issue - horizontal white lines, cause for warranty?

First of all, my SGS2 was bought 18 months ago in April 2011, I think Samsung phones come with 2 year warranty I heard?
Now the problem is with my display, there are horizontal white lines running across the screen (in landscape mode, they become vertical white lines, ie they do not move with the screen orientation). Now they weren't there when I first got the phone, I think the problem has become more and more with usage.
It's likes a banding effect? burn in effect? dead line of pixels? It's worst on white backgrounds (obviously means the "white" background isn't as white as these lines) but lately it is seeping into all pictures (so on a blue picture, there are white lines running across), ie I can see white lines across them all. Obviously nothing on black backgrounds because nothing is being lit. Defect in the Super HD AMOLED+ production?
I didn't bother sorting this out earlier as it was usable and livable but I do believe the problem has gotten worse because even 6 months ago it wasn't this noticeable. Also, I have a new Note 2 coming tomorrow, so was going to sell the S2 but obviously I can't in all good faith knowingly sell something defective if I could fix it by warranty.
damn it , i hv this problem also, after sent to warranty, before sent to warranty dont hv this problem ,o0o samsung

Sorry dude, but Samsung only serves ONE YEAR SERVICE WARRANTY
on the side note, the S2 isn't really "great" when it comes to screen quality, i must admit.. I have that "lines" too.. so i sold it to get an s3 :victory:
Says 24 months on their website.

[Q] Dead pixel on new S3 device

Hi,
I just received a new S3, and I'm noticing what I would call a couple of dead pixels: on a white screen (but also red & green, on blue it is not noticeable/ I cannot judge) at any brightness, there are two distincs points (I would say, pixels) that remains black.
When magnifying the zone with a lens, I can notice the defect is circular with the size of few pixels (<10) with lower luminosity then the rest of the display, with the center emitting no light.
Anyone with the same experience? How this is evolving with time: starts working? worsen?
One pixel is towards the border and just the second (in the center) bothers, but effect is very small and noticeable only when you know it is there.
I took the phone on Amazon, so with great flexibility for returning it, but I got it on .de (and I'm living in .fr) because of the great price (359€) and it is a bit annoying returning it.
Thanks for the feedbacks

My solution to a stuck pixel
About Dead/Stuck pixel on OLED Device Display
I have a S3 GT-9300 that I use daily, the other day I dropped it on a hard surface and a single shiny green stuck pixel appeared on the bottom left corner of the display, it was a bit of an eye sore really, But I'll share my simple FIX if its a related problem like mine was*I thought if the drop caused it, then a related solution may fix it, so I simple activated display and went to the home page.then I turned the display facing my palm and held the device carefully at the top end and slapped it several times hard into the palm of my hand where the pixel problem area was. then stuck pixel went away...
I hope this works for you too*
@^
Well, that's certainly one of a kind....
So noob, just send it back. No biggie It's Samsung's fault for having appalling build quality. So just go into the store and scream your head off till you get a new one, or preferably an s4 for inconveniences.

One Dead Pixel

I have one dead pixel. And minor light bleed negligible.
Worth exchanging at best buy? Neither really boither me but that one dead pixel plagues my mind.
Also if device acts up after 14 day best buy grace period how would i rma it? Should i have gotten bestbuy protection plan?

You say neither bother you but the dead pixel "plagues my mind". A dead pixel would annoy me and I'd go for an exchange personally. Thing is with dead pixels, once seen they can't be unseen easily and you'll keep seeing it, go for an exchange is my advice.
Light bleed is part of the technology, and it varies between devices, hard to find a display devoid of it completely. If you look at any TFT display with a black screen that has a bright back light, light leaks through unevenly to some degree. If it worries you it is case of finding a good example, which isn't always easy unless you can unbox an unlimited number of them and try before you buy.

Agree. Return/exchange it. After 14 days, it goes to htc for warranty repair.

[Q] Prelude to dead pixel formation?

Hi, i've had my samsung s3 for about 20 months now nearly 2 years and so far so good.
however i have been reading that AMOLED screens eventually have dead pixels and ideally if you were to get them it's before the 2 year warranty window rather than just after.
My question is before you started to get the dead pixels and black spots on the screen did you find that it would go away for a bit then come back?
just now when i backed out of an app i noticed there was a big black mark dot on the screen.. larger than one pixel but maybe like 4-5 in a circle and also to the side of it a slightly discoloured pixels of red etc.. when i swiped through the windows where my apps were it all went away. was this just a glitch from what was showing on the app i was using (with black screen and red colours) or dead pixel potentially forming?
I have no idea what dead pixels look like when they're dying.. though i do know it's all black when they're dead.
is this most likely a glitch or have you guys who have had dead pixels before noticed something similar just before they died?
I've a Droid RAZR for 3+ years now. No issues with the display till now.
I think not all displays die like that..
