Yep. They'll, at free of cost! :good:
Hello. Sorry for your device. Could you post an image of the bad display part? Thanks.
You cant really see it in a picture but i can see the dots while using some apps its really annoying and on a dark image there are many of them
I also got a faulty phone with dead pixels all over the screen than i got a replacement from flipkart which also had a faulty display with a big white spot in the middle of the screen but than i got it replaced by service centre free of cost. But one thing i can tell is that many redmi note 4 phones have the same dead pixels problem as i have seen many people with faulty screen around me. Xiaomi is not having tight quality control.
Hmm.. Let me tell you my story and what I came up with after a small research.
So I had got my Note 4 (4/64GB Variant) in February this year. Right after a week or two, I noticed some stuck pixels. Initially they were just one or two, but then they started expanding and scattered all over the screen. I can't even tell you how ugly the screen had started to look, it had more than around 50 stuck pixels all over the screen.?? It broke my heart and I desperately wanted to get a replacement. I then started to notice some of friends' Note 4 and coincidentally, they all had some one or two stuck pixels. Then I came to a conclusion that the Redmi Note 4 has a serious quality control issue with almost 85% of defective phones. Now, just a week ago, after a lot of research, I went to an authorized service center. (Thanks to Xiaomi, we now have 500 centres in India). I noticed their reactions when I disclosed my issue to them, they were quite ok with the problem and told me to wait for 2 hours. Now, from their reactions, it was 100% confirmed that its a common issue in Note 4 and many people have got a replacement.
So, without any hassle, they replaced the screen, but took 2 hours extra, but it was ok considering the usual croud at Mi service centres we see.
The replaced screen works flawlessly and the next thing I noticed that its now a Tianma display.
So, wrapping up the whole story, I'd conclude as:
1. The Note 4 manufactured in the Indian factories use a defective NT335 display and has issues with 85% of their production.
2. The service centres always have the stock of only and only Tianma displays.
3. You can get the screen replaced quite easily as its a very very common issue with the Note 4. Just remember to carry a copy of your invoice to claim warranty.

i used a redmi note 4 with tianma display it had that text blur issue on scroll. I want the display model which came with the phone. The other redmi note 4 that is in my house has the same model display as mine and has been around for a while now and has no dead pixles while mine has had them since the beginning. I was really shocked after seeing this.In february when i got a chance to use a note 4 i noticed stuck /dead pixels on it so i thought its a issue with all but seeing newer phones with fine display is really shocking for me

is there an Quality Control issues I should be aware of before buying the phone?

I'm thinking of buying the (international version 128 GB version) F1 but the process would including importing it which means no warranty. I'm worried if there's any sort of QC issues that I need to aware of because returning or even replacing it would be quite difficult. I got the redmi Note 3 back in the day and 3 months later the MOBO failed. I returned it for a redmi note 4 which also failed because of QC issues less than a year in so I don't have much faith in Xioami's productions quality. I've also seen that the screen failed every drop test it went through. is a case and protector that much needed or can I get away with a Dbrand skin? I'm coming from the HTC M8 so idk how durable blastic phones are.

Screen bleeding check and audio quality check
I have used redmi 1s for 4 years with original battery and everything. I have use redmi note 3 for 2 full years. Didnt had a single issue. Poco f1 is a very good choice for its price i would say. Screen is not good. But not bad. Its ok. Camera is best in this price range. If you want a performance phone with some compromises than its best phone in market. If you can wait. Wait for poco f2

Genuine replacement screen?

Hi, I replaced my pocophone screen due to stuck pixels and touch issues, after I got it it was Wrapped in a sheet and it says : " after sales front cover display module redmi note 5 black", is it genuine?, keep in mind this official xiaomi service center.

Phone fell down; need to replace screen, back glass and fingerprint sensor

My Z2 fell down from a 1 storey height last day . The phone is still usable but the screen is cracked on the top right corner. The touch is not working on that side. I can't swipe down the quick settings from there. There's a little touch issue at the bottom right side also I think. And the back glass is almost completely broken. I had applied a carbon fiber sticker on the back earlier so the glass is still there fixed.
Also the fingerprint scanner is not working. There's a scratch there too. But the press function of that button is working. The shape of the outer frame of the phone is changed a little bit.
I just reset everything again and flashed AOSiP-9. Except the fingerprint and top and bottom right touch everything is working I think. I'm posting this thread from my phone so it is still usable.
I want to know how much will it cost for the front screen, back glass and a new fingerprint sensor? I went to the nearby Lenovo service center but none of these parts are available there.
Just found that the it'll cost between 2500-3000 for all these parts. The screen is also broken a little bit. So both the touch and screen should be replaced.

I bought a pre-owned OnePlus 7T yesterday after long-time research. It has almost everything I like. The only issue is that the lack of custom ROM development support but I'm waiting.
Meanwhile the back camera of my Z2 too also stopped working. I replaced the fingerprint scanner and the touchscreen myself with another dead Z2's parts. All the area is now touchable but sometimes it freezes too much. Now I can use the Z2 almost okay, so I'm still using it as my daily device with AOSiP-9. I decided to use as long it can run without any serious issues.

I paid ₹ 30k. It has extra accidental and screen protection worth around ₹2000. The first owner bought it in October. If you are buying a pre-owned you should not spend more than 31k even it has extra protection as it is available in Amazon for around 35k, and with credit or debit card you can almost save around 1.5k to 2k. But please check Amazon for the card offers.
I chose 7T over 7 Pro and K20 Pro because of some personal reasons. But I recommend if you are upgrading from Z2 and you can afford, please buy this as it has almost all a flagship needed and doesn't have any extra gimmicks like motorized pop-up camera. Because only a few phones have this motorized type of cameras and the current trend is having a punched hole camera. The notch is a way ahead of this punched holes because you don't feel that much distracted with notches. I tried latest Samsung phones and I felt too irritated with those ugly punched holes. A few upcoming mid-range phones are coming with these as per some news. Anyways these are just my personal reasons.
I'm quoting my own text that I replied to someone.
"Yes bro, 7T has almost everything which I wanted and lacks only a very few things. Like it has a
+ non-popup camera so faster face unlocking
+ 90Hz of course
+ stereo speakers
+ 3 cameras with a wider one and now with a super-macro mode
+ OIS
+ less weight compared to 7 Pro
+ 855+
and pretty much everything a flagship needs. The only thing I miss is the QHD display. I have a VR/AR device so I wanted to use it for watching movies like in a theatre. The QHD display has less pixelated view compared to fHD for this use. But compared to other specs it is not a deal."

Can you tell the display manufacturer before buying the phone?

Hello!
I've read that there are two display manufacturers tianma and huaxing So which is the better one and how can I tell before buying the device?
From what ive read from a 9s/pro facebook group, most of the screen bleeding issues is with huaxing panel. I personally have tianma display, it has no bleeding and retention (as of now) but it does have some shadowing around the notch. And you cant tell what display you will have have unless you opened and checked it through engineering mode, its most likely a lottery really.
How exactly can I check which panel my phone have?
Checking the LCD manufacturer:
https://all-spares.com/en/articles-and-video/how-to-check-the-lcd-vendor-in-xiaomi-smartphones.html
...but Redmi Note 9 Pro is not showing the LCD manufacturer there.
I have huaxing panel with no issues. There's no bleeding even if I put my screen on black. But thanks for asking!
My phone has a huaxing screen too, and I have no issues.
Sometimes I have the feeling people are SEARCHING for something the can hate on a phone...

Better to know it beforehand than to cry about it later.
If only your display misbehaves, you'd feel the real pain of getting a faulty display of previous Redmi and Poco F1 owners :crying:
My Redmi Note 7 had Tianma panel and it was really bad... Keyboard with lag and a lot of screen retention/burn. Now my Redmi Note 9 Pro (max, 6/64, 64 megapixels) have Huaxing and that problems are not present, by the moment.
But in YouTube you can see many videos with redmi Note 9 pro speaking about burn ins, ghost touches, etc. Typical tianma disease. For now maybe not many (?) users get this problems, but how these screens behave over time? Is screen from Indian unit (9 pro) different then from global (9s)? I can see more Indians completing. And trust me, they don't complain without good reason
I have one week to decide either to buy this phone or not. I would really like to believe that everything will be fine etc, but I've almost lost the hope
