Problem with the display - Xiaomi Mi A1 Questions & Answers

Hey guys! My device was having screen burning problem so I went to the service centre and they replaced it with the new display panel.The recent one was tianma and now they put ilitek one.It is working fine but it has very warm screen temperature,it's just unbearable.I tried many applications to apply blue tint to my screen but they just mess up the colours while correcting the whites.
So is there something we can do to improve the display quality?
And is there anyone who faced the burning problem with ilitek displays,I searched everywhere but only tianma displays seems to be affected.
(To know about the display vendor dial - *#*#64663#*#*)

I have ilitek and its not having issues.

Don't have another Mi A1 with another LCD vendor to compare it with!

I have 2 devices, one with Ilitek and other one with Tianma, comparing those two the one with Ilitek has more natural colors, for me the one with Tianma screen is too cold.

I dunno about the quality of your lcd panel, but mine is ilitek too, and i find the colors just fine. Yes it's a bit on the warm side, but it's ok. Color accuracy and contrast is good too.
Actually i only notice its warm tone when viewed side by side another phone with colder tones

How much does ilitek LCD panel costs?

I am facing screen burn issue !

You can determine it by noticing the colour temperature,the warmer ones are ilitek and colder ones are tianma.

Yup. See the pink line running along the right side of the display? Thst with the washed out colors mean the lcd is junk, and needs to be replaced.
Thats probably why you got such a good deal on it.

Very curious screen anomaly.

I have these 2 very light yellow areas on my screen.
Here's the interesting part, they don't show up on screen shots. They also appear to be getting brighter.
A new screen is probably the only fix. But I'm curious of the cause. Any ideas?
I have included a sample of the issue.

Did you draw that in paint on a screenshot or take a picture of your phone?
If they are hot spots (bright white dots) then they are part of the screen and a new screen is the only issue.

My first buy had similar problems. I exchanged in a store for another.
There were lots of defective screens in Poland.
Factory reset can help for few days.

I drew that because they do not appear on screen shots. Could the color be between the LCD and the digitizer?

The colour is because of a ****ty screen. @acejavelin mentioned in another thread that they are caused by compression for some reason. Don't know how that happens. Like @dzidexx said another screen is the only thing which can solve it. Or deal with it, I do not know how bad it is sorry

Defect rather looks like "Lights behind the closed door".
Do a black photo or jpg file. Look at it with different levels of brightness.
Sometimes it can be observed with other colours.

The last two pics are it exactly. Even though its a little annoying, I still love this phone!! Its the only issue I've had and I use it a lot. For everything. Between flashing, modding and every one of my boot animations has been made on this beast!
And thanks for all the input on this issue everyone.
And sorry to all those who suffer as I do with this affliction. Just kidding.
It's happening to me too. It's starting from the top right

Hardware !! Read the thread and you'll see it has been made clear it is hardware.
I have the same issue. If I press on the bezel next to the yellow area with my fingers the colors go back to normal until I release. Could this be caused by the screws inside being too tight?
I would disassemble my phone and try to unscrew them a bit but since the back cover is glued I'd rather not unless I'm sure that's it.

Ghost images on status bar.

Hello XDA members,
I have noticed weird behaviour on Mi A1 stock Oreo.
Ghost images from previous notification and status icons is seen on status bar.
Initially I thought its launcher(official nova prime) issue and changed it(now lawnchair) but issue remains same.
Did anybody else also noticed this(attached image)?

That's screen burn in. You won't see them in the screenshot. Usually happens when you use your device with much more brightness, or you keep your screen on for a lot of time(usually more than 10 minutes).
If you don't do any of the above mentioned things, you should visit the nearest service center, because the screen might be faulty.
Its happens .. U can go to service centre and claim ur warranty. Nothing to worry. 2 of my friends already got it repaired. They changed lcd panel to something else. Both of them have Tianma display earlier
If is it a Tianma display the chances are good to be burn in.

How can I figure out if the display is "Tianma"?
And what does that even mean?

It's a brand. Most of them are colder tinted blue. EGGB brand is something more warm maybe yellow/green.
Type *#*#6484#*#* in dialer and go to" 1. Version Information". There you will see LCD: GFF, vendor: XXXXXXXXX
The XXXX thing is the brand.

Ilitek is EGGB. Focal is Tianma. Now you feel much safier
Apparently my friend has tianma too. But he isn't experiencing burn in. Can he still get his display changed?
Edit: I visited the service center with him. Those guys were noobs and didn't even know what a screen burn is. I explain them what it is. I even gave them a live demonstration, which worked and gave the burn. They still insisted that it's a software problem.

This is not as 100% sure that someone will have the problema with Tianma display but only more probable. I think that your friend or anyone have to use the smartphone as usual and if the problem shows up in warranty period then go change the display. Don't care too much about it because is more probable don't have it.

I get it. But, I was actually able to convince them. They've called him in the next week for a free screen replacement.

Can someone tell me this exact part?

Hi guys
I have a used V20 but the colors of the icons etc are quite dull compared to my wifes V20 and also the whites are more yellowish when compaing side by side. Which part of the phone affects/determines the LCD colors? Is it the digitizer itself or does it have to do with the mainboard producing the colors?
Thx!!

Yes i have it turned on. Screen colors are still quite poor compared to my other V20. Colors seem faded a bit.
Im thinking maybe its due to age or wear. But our phones arent THAT old.

Screen ghosting/ image Retention

So, I am 1 unlucky in 1000 who has a tianma lcd panel and facing screen ghosting since one month after buying the Note 7. Is there any software fix for this? I heard Redmi note 4x has similar issue. It doesn't affect performence but unpleasing to the eyes. I am not looking forward to replace the lcd as the phone us still brand new. It is imported, so there’s no way to return it. Thanks in advance.
Same thing is happening to me, sadly... Don't think there's a way to solve this through software, as it's a hardware issue
Bought Redmi Note 7S (Lavander) Onyx Black 4GB/64GB Yesterday , Faced Touch Ghosting.
Edit : Requested For Replacement * From Flipkart.

Actually, I did a little goof. Turns out I have a BOE panel instead of Tianma which is good, but even on that panel, I still get some ghosting... so I can't imagine how bad it must be for the worst panels Guess that's what you get when you cheap out on a phone

Wouldn't I need to pay for the replacement? Or if covered under warranty as it's a manufacturing issue?
So basicly even if you replace the phone under warranty, you will get the same panel and the ghost screen will be there again after some use?
you can use this tips to modify the display color a little, to minimize the ghosting effect.
I have tianma with pretty nasty retention, and modifying the display kcal does the job.
**You need use custom kernel with kernel manager or simply a LOS-based ROM to apply this mod.
I have tianma, everything just looked fine, this is only "things" , not she or he , so for me just use it
Fix for now
I thought I was the only one. Bought this device from China and started having this issue after around 4 months.
The problem does not occur with pitch black wallpaper.
I did some research and found this app (Ghost screen).
It's not in play store.
https://apkhome.net/ghostscreen-1-0-1-4/
I do not face the problem anymore.
Try it. And let us know.

Image retention is gone when you do this. Its a must to do this if you are facing the issue.
Pls what Los ROM in particular
Redmi Note 7
Image retention
Solution in Pixel Experience Rom
I found a workaround in the pixel experience rom without any apps .
Go to Settings > Display > Live display > Colour Calibration > and set all 3 values to 92.
Weird. I have a Tianma display, yet I am not experiencing any noticeable ghosting. Maybe your screen is faulty.
