Camera feed flickering - Xiaomi Mi 8 Questions & Answers

Hi,
I bought a Xiaomi Mi 8 yesterday and I have noticed today when taking some test pics that the flickering (banding/white pulsing effect) was really bad under LED lights.
I know this is "normal" but I compared with my old S7 Edge and some random colleagues iPhone 6 and the flickering was definitely much worse on the Mi 8.
I tried to change the band frequency in the settings but the improvements were minor.
Can this be a defect of my phone or does the Mi 8 camera just sucks on this?
Cheers

Will a custom rom fix my Mi 8 problems? Stock camera is a potato

Recently I got my Mi 8 running MIUI 10.0.0.3.0 (Stable). It is a global version with a locked bootloader right now.
I got a few problems:
1) Camera shutter sounds within whatsapp/instgram even in silent mode
2) No notifications in the topbar (I heard that the beta solved this), only if slide the notification bar down
3) Camera quality, oh gawd. It's really awful and like two steps down from my S7 Edge. Red colors are shown orange and the details are missing. This is ridiculous. Saw a few reports about this.
4) Sometimes even with silent mode on I hear the notification sound
Most imporant point is 3) that I want to get fixed. Will a custom rom fix my problems?
Also got any recommendation for a custom rom? I want it stable, maybe a few tweaks (like accu percentage) and I need magisk for google pay.
Try Havoc or Pixel3ROM and see if you like any of them.
Can you post camera samples? I"m curious to see what bad shots on the phone look like. Mine are excellent.

Some if not all of these can be fixed after an update. You should also attempt to mess with the camera AI, HDR, etc. to see if your results change. Usually custom roms make it uglier, but IDK about the Mi 8. GCam seems to be stealing the show, try that perhaps?

He may be talking about the pixelation issues, especially when using some app's camera feature, or in poor indoor lighting conditions. In the beginning I broke my head as to how it scored such a high DxOMark when I took shots in my place, which is not that great. Then took some outdoor shots, shots at a friend's place (with better lighting) and some shots in very low light at night and was stunned.
I also got the mi 8 since my S7 Edge is getting old and when playing with the camera on my office I noticed massive flickering (banding/white pulsing effect)s.
I know this is "normal" but I comparing with my old S7 Edge and some random colleagues iPhone 6 and the flickering was definitely much worse on the Mi 8.

question about quality off mi9 amoled

Hi quys!
first of all ,sorry for my bad english!
but, i recently bought xiaomi mi 9 , i had lot of problem with it till now but the most important of it, its about display panel.
my perivious phone was samsung s8 Plus and s8 display was awesome (its 2 years before phone) but my mi 9 display not good as s8 plus , not even close, is this normal? or my phone have problem software?
Hi, what problem did you get ?
I had the reglular Samsung S8 and I find the Mi9 panel not far from the S8. As it is 1080 and not 1440 it has not as high pixel density, but I am more than happy with the Mi9. Never have any problems in bright sunlight as I could have with the S8.

thanks for your reply, but i a disappointed the first time i saw mi 9 display. i think the icons are like washed out and not sharp. i saw someone in this forum said after update mi9 , have a better display and compared his phone with S9!
my next problem is updating miui. my mi 9 is china pack and the website that i bought my phone , open phone box and flash global rom on china rom in china country and send them to customers. i have weird problem with the phone.crash app frequently ,google play service crash and stop ...,the worst problem is closing all apps and go to lock screen and after unlocking phone ,the message "find device closed unexpectedly" showed me and if im not reboot my phone this problem repeat and even sometimes my phone reboot itself even twice or more. now i signed out from my mi account and i turned off sync option and set off battery optimization and lots of setting option, and betternet app (vpn) not use anymore (this app made a lot of problem for me , i think) and now i have a better experience. i wished a new update fix my all problem . i am on V10.2.9.0.PFAMIXM Global Rom and new OTA Update V10.2.13.0 shown on my phone after downloading update , my phone reboot to start the update but after 25% in fastboot update failed and not update this time OTA Update is 2.2GB . i repeat this process a lot and no progress. even downloading zip file by PC and update manually not help, phone it said this is not official update.
what is the problem of my phone for OTA Update!?
You might be looking for more vivid colors. Go to Settings, Display, Contrast & Colors, and see if moving between "increased contrast" and "Standard" gives you more of what you expect to see. You can also set the color temperature to better match what Samsung uses by default

Yes, didn't think of that as I always tune down the overly saturated Samsung displays!
The auto brightness also seems to be a bit off. I have my brightness forced.
If you have DC dimming turned on, it can also change colors if you are on a lower brightness.
Coming from note 8 i am very satisfied with the screen, if the note is a 10" the mi 9 is 9,5". (i change the settings to be more vivid). I

K20 Pro Display Issues

Recieved my K20 Pro yesterday and I've noticed that there's a slight green tint on the upper left corner.
Here's an example.
imgur .com/a/Tr9b61H
It kinda goes away on 80%+ brightness and also appears on white and that gradient, sadly I can't take a photo on a white setting because it doesn't appear on the photo.
Any people out there that has a Mi 9T, K20, K20 Pro that is experiencing the same problems?
We can also share problems that we experience here so we could test it on our devices, feel free to share! Thanks!
Additional questions:
1. Also is there any way to know if the device has been used, returned or a refurbished one?
2. Idle temps is 35c, when gaming it reaches out to 50c~55c. Is it normal/okay?
3. The thing is if I refund or return I'll be getting the same device, so do you think it is worth the hassle?
Sorry I'm a new account so I could not post links. Thanks!
I'm on the latest MIUI version, no other changes made.

I bought the Mi 9t pro on the 28th august and it had some issues so i returned it and bought a new one. Arrives today, we will see, i would reply if the problems repeat
the problems were:
1: With the dark mode activated, The contrast with true blacks and gray, while moving the screen, the pixels that had to turn from black to gray had a Blue/purple tint. most noticable with Less than 50% brigthness
2: with, again, gray tones ,the screen had a line in the middle across the display that had a gradient towards white, like in spotify, for example, wasn't a solid color.
3: Some touch issues, most noticable while gaming(Call of duty mobile in my case)
Similiar issue. @oliese have you returned it, or its normal scenario with led panels?

Xiaomi redmi note 9 problems

Hi guys,
my girlfriend recently bought a xiaomi redmi note 9 and oh dear, there are so many problems with it. The most annoying problem is the camera quality. It's just really really bad, it's pixelated and you basically can't take pictures with it (it's pixelated, not sharp etc.). The second problem is also related to the camera itself - the snapchat quality. It's actually pretty funny, because everytime my girlfriend wants to take a photo on snapchat she has to shake the phone like crazy to get the camera to take a better quality picture. Otherwise it's pixelated and just bad. Is this a hardware problem? I told her to check for updates etc. but nothing worked.
Also the animations are really really bad. They are laggy and just unsmooth. Whenever she tries to open an app the transition animation is really laggy and it's just unpleasant for the eye. I tried setting the animation scale in developer options to other values, but it didn't help. Again - a hardware malfunction? Or is it more software related?
Would be thankful for your help
May you record it?
Apparentely, you need another phone by warranty.

Question Realme GT 2 problem with AMOLED display and text visualization

Hi, I recently bought a Realme GT 2 8/128GB Global RMX3311_11_A.14 firm and have been using it for past couple of days.
What I have noticed like artifacts around black text on white background, like a bright halo under dark shapes and clear/light background, it's like a 1px brighter-than-the-background, like a broken anti-aliasing/ClearType or maybe is that the sharpness is very high.
I have tried all the configuration options available for the screen but there have been no changes. For example, in the list of Wi-Fi networks, in the password field, if you look at the black line, it is in one of the places where it is most noticeable.
https://imgur.com/t50LOm5
it is very difficult to capture with a camera, this is not my phone but the same thing happens
https://imgur.com/zOkyWWG
I think i have same problem which is reported in this other thread for a Xiaomi phone https://forum.xda-developers.com/t/over-sharpened-mi-11x-amoled-display.4319715/
Is this normal or there's any problem with my display? Is this a Realme UI 3 issue and can be solved in following updates?
I have other three Amoled phones and this DOES NOT happen to any of them! (Realme 8, Oneplus 3T, Xiaomi Mi A3)
thanks!
regards
Do you have DC Dimming enabled ?
I noticed that when it is enabled in low brightness and black background there's some flickering on the page text when scrolling.
But that particular issue I don't have.
Hi apsol, thanks for your answer
No, I did not have DC dimming active, I have tried to activate it but it has no effect on what I comment
with time I'll get used to it, now I know it's there and I see it. What I would like to know is if it is a problem with this AMOLED panel or rom/driver issue which could be adjusted via software
I know how it is, once you see it you can't unseen, it would drive me nuts too. Hehe
Have you tried testing for dead/stuck pixels if it doesn't show there my guess is software.
I'm on RMX3311_11_A.14.
What about you ?
Hi,
Same firmware version here, RMX3311_11_A.14 global
the truth is that I am not sure if it also happened with the A.13 because I almost updated it at the moment, I did not realize this until I was in the A.14 ...
thanks
The same problem on my phone. It is easier to see also on black background with white font.
Unfortunately I think this is a screen issue not soft
Have anyone have similar issue? Is this global problem or only 2 of us struggle with this issue?
Check if you have high contrast text enabled.
I have high contrast disable ( but the same issue is visible when option is on). Do you have this is issue? Or should I send my phone on RMA?
I don't.
If it bothers you that much return it.
Hi again,
After continuing to search for information on this issue, I found following post on reddit that I think has the same problem with an iPhone 13
https://www.reddit.com/r/iphonehelp/comments/tdy5tc
I think it's a common problem with AMOLED screens, but in some it is more noticeable than in others and it also depends on the user
after detecting it on my Realme GT 2, if I make an effort, perhaps I could say that it also happens on my OnePlus 3T, however the difference with my Realme is remarkable, the same with a Realme 8 of a family member
By the way, another thing that I have detected is a color shifting when the viewing angle is varied, much higher than in my other devices with AMOLED, it must be said that the larger the screen, the more noticeable it is
I'm a little disappointed with the screen to be honest
thanks

I came specifically to this forum to check whether its true about the screen's colour shift and font edge issues. Seems its true. Its believed that they have used the same samsung E4 hard screen, that they used in oneplus 9RT. You can check 9RT's display review below:
https://www.gizmochina.com/2021/10/22/oneplus-9rt-review-perfect-balance-camera-price/
There is also a Chinese video on GT2 display. Its a review of k50 and gt neo3, but they have shown display of gt2 also. Watch from 2:30 min.
I don't see that problem on my gt2 in normal use.
I also have the blue shifting even when looking straight. I try to ignore it.
Someone told me it was the screen protector but I never removed it to be sure.
But every review I've seen there is color shifting.
