Dark line on display - Redmi K20 / Xiaomi Mi 9T Questions & Answers

My 9T display when there is low light, the brightness is set to low and the image I see on the display is darkish I can see a vertical line at the right side of the display, is this normal or should I return It?

multiple users reported similar issues with low brightness, some said it's a rom issue but to be sure, post a screenshot or something and wait for others to respond.

Exactly in the same place, I think it's a recurring problem on this model.

Replaced the phone and there is no line in the new one, you should return It.

I don't have something like that on mine. Looks like banding to me, like on TVs. It can happen, it's probably not important. Screens aren't perfectly uniform.

lighter spot on gray background on the screen ??

i just noticed 2 spots one on the right and the other on the left
they appear as lighter than surrounding area in a gray background only in low brightness
they are ill defined .... not a ring
i ll post a pic later on
any help about this ??
I believe this is a limitation on the SAMOLED+ ( was not there on the original SAMOLED ) some phones dont have this un-uniformity of rendering greys but probably a good majority have.

i searched before posting but didn't found any similar thread
so whats the problem ..... is it normal
it is not obvious but it is annoying to have it in a new device only
in normal use i don't see it but the only screen that i can see it when looking for battery usage as it gives the screen a plain gray color

You have 3 choices:
1. Do nothing - no problem under normal use, so why whine?
2. Return the phone.
3. Find one of the 306507 threads involving screen defects and filled with the rantings of some of the most disturbed people you could ever wish to meet. Won't "cure" your phone, but it may be of some succour.
I recommend #3 for you.

I fail to see any screen artifacts, all I see is jaggies and that's not screen artifacts. That's just a lack of anti-aliasing.

Look at the leafs. they have some kind of black background around them.
and yes, happens on mine too.
Did you reboot phone? Uninstall and reinstall game?
If its still bad then email developer. Game looks quite cool, might buy it if they fix the issue. Post them the link to this thread in the email!

Yep i did that several times but nothing helps.
Game uninstalled!
It looks like the leaf images are supposed to have one color mapped to transparent. What image format is being used? GIF?

look at the difference in color of buttons "1" and "0" .
Does anyone have screen that have same color on the sides of the keyboard ? if u do please take a picture of it in low light room with minimum brightness.
This is not an "issue" no screen is perfect. You will have VERY SLIGHT discoloration here, while other will have it there or not at all. If you don't understand this, you will be annoyed by yourself always seeing that slight default

i want to sell it . And the question is - does anyone have perfect screen on note3 ? So i should buy another note3 or other device ...
perfect screens dont exist. Perfect cars dont exist, perfect people dont exist. Perfection doesn't exist.
I can say that i have a perfect screen, but then again, i wasn't looking for an imperfection like some members here tend to do. I'm sure if I start looking for one, I might find one, but whats the point? Unless you have a dead pixel, or distortion, its not this TINY difference in tint under the right lighting conditions thats will prevent you from selling it full price

[Q] N4 rear flash ring?

Hi there!
i recently bought an N4 and i love it but i was wondering why my rear flash is like the way it is (see pictures). I bought it completely new, or supposedly new, on ebay for around $200... i actually couldnt believe the price haha
any comments as to how to replace it? due to the flash lens/ring it allowed dust in the rear camera which is so annoying.
thanks!
I dont know, but my flash looks completely different. You sure that is a nexus 4 and not some fake stuff?

haha yeah it works perfectly fine though
another thing i noticed was this... i dont know if it's normal either
there's vertical lines when the screen is off and noticeable when caught in the light at certain angles........
i'm starting to think this was a broken phone but refurbished after
the rear flash ring is normal but the bars on the screen is a new one, i have never seen that, its usually a clear screen and you can see the dots from the digitizer from different angles.
maybe the screen has been replaced?

Wow, I've never seen such vertical lines on my n4 before. That is really strange, mate.
Although there are horizontal lines/patterns on the screen. They are conduction medium for the touch screen, but no..never seen such vertical ones...

Those who have S7s already, any hardware quirks/flaws to look out for?

My S7 Edge is coming tomorrow and I'm always paranoid about things like stuck pixels, dead pixels etc. Have any of you noticed anything that would make you want to exchange for another device?
Yeah. My S7 has way too many pixels. [emoji23]
Sent from my SM-N920W8 using Tapatalk
got my s7 last wednesday and i absolutely love it!
no dead pixels, vibrator is strong, buttons work well and are responsive, speaker sounds fine, and the glass front/back are perfectly clear, not a scratch on it. And the Titanium Silver color is beautiful! I really don't want to put a case on it!!
Samsung has never let me down in terms of hardware flaws out-of-the-box.

No issues yet. Only quirk is installing apps. I Cannot find the option to disable "allow Google to regularly scan".

I dont know, maybe the glue or any protection more than normal, see this vĂ­deo bellow, 3:38 second and you will see, all s7 edge have a green tone when have in a white image, for me it's annoying and is why I won't buy that model, I love the edge but this feature/annoying thing for me it's impossible, I constantly see and see the problem.
