Hey there,
I have some issues with the MTCB. Someone had these before?
First problem which is already quite annoying is that pictures are kind of burned in and still show shadows on the other screen
Second problem which is even more bad is that the display flickers. This is more or less obvious in different scenes.
When looking closely it seems like there is a grid (coming and going in the same frequence like the music is playing?). The attached video shows it.
Especially with white background the flickering gets very bad.
Don't know if this could be related to the Malaysk Firmware I use. Or is is it a hardware issue?
Also contacted the support. Let's see what they say...

Sounds like a screen issue to me, have you checked the ribbon connector hasnt come slightly undone ?
Hi, thanks for answering.
Attached is the video I spoke about. I missed to upload it.
You mean to open the device and check the ribbon connector inside, right?
Regards

This is commom in these units.
It's worst when it's hot.
I kinda fixed mine opening it and adjusting some kind of screw near the screen. You turn it and screen gets darker, you need to find a point between too dark and flickering. But when I park my car at the sun, and it gets hot inside, screen get bright again, so flickering and persistent images.
And here is a video about it.

It's commom. That's why Joying even put a video online to show how to fix it.
I believe that when they produce the unit, it's now well tuned up, or it's cold in the factory and they don't realize, so when someone who lives in a hot weather area install it, the problem appears.
It's a bad hardware design, they use analog potentiometer, they should use some digital and automatic one to regulate screen frequency.

Well, Like I said, I ve not heard much about it in the 3 years I ve been following the threads on here, but I do remember Joyous having problems with their screens and 5.1.1 - they couldnt get 5.1.1 to work on their 4.4.4 RK3188 units unless the screen was changed !! Sounds like its more a problem with Joyous units.
I agree there's not many complaints about this problem here, that's why I believe that may be some "quality check" sloppiness. It's very simple to solve anyway.
But all units seems to use analog potentiometer, so, bad design. There's nothing to do with Joying only and the fact they changed screen to update to 5.1.1.
And most users in this forum don't live in hot weather areas. In my case, Brazil, is hot must time of the year, above 34 C degrees (93 F), in the shade.

Youre envious of 4 deg C ?! I get 34 deg C is a bit hot, but 4 is a bit cold !
Half way between 4 and 34 @ 19 deg C would be perfect

I looked at the map and St. Helena is a little to the south, a direct flight seems a better option.
But feel welcome if you want to come to Brazil someday.
It's a bit messy but it's a good country. I'm not going to take you to meet any favela, by the way. Don't know why tourists are so eager to go in one, it's very dangerous, and I don't think they represent Brazil that much, so many different beatiful places to go.

Hey there, thanks but the video is not working.
I did not open the unit yet to check if the screw will improve. But I will test soon when I find some time.
By the way it's around 0°C here. So not very warm
Attached is another video. The flickering of the right white picture is actually visible. It's not a flickering of the camera.

Just open the unit and fix it, very easy.
Took some time until I tried the fix. But the screw fixed it.
Carjoy recommended a power filter, but since the screw fixed it i prefer this...
The screen is now slightly darker. But I like the crisp image and better saturation of the colors (and of course no flicker).
Thanks!

I recently received a refurbished Pixel XL from Google (warranty). The night light mode seems very orange and dark compared to my old one. Is this how it is supposed to be?
No.
The only time I've seen my night light orange was on a custom ROM that I guess had it miscalibrated or using the wrong driver.
Have you tried wiping and updating to the latest firmware yet?
I factory reset and it's up to date. Looks like it's going back.

What is your brightness set at. I can make mine look like that if I turn the brightness down to 25 percent or so. Once my brightness is up to 60 percent or so it looks exactly like the images of it I can find on the web.
It looks different because the camera is not able to pick up the proper exposure, I think its the same as ours. The mode is pretty yellowish/orangish indeed.

That is exactly how mine looks. There is nothing wrong with your device. If you don't like the way it looks perhaps you best not use it. I only use it for notifications at night and not for reading. It's just too dark to read an article. So it looks like your first return was a waste of time since it's not going to change no matter how many times you RMA the device.

Orange Night Light
Has anyone found a solution to this yet besides sending it back, mine had the same issue and the next one they send me was the same way.
Enabling sRGB mode in Developer Options makes Night Light look much less orange on my Pixel XL.
In Android O it gives the option to control the amount of tint you want. On my replacement pixel, the tint isn't as strong as my first one.
Just chiming in, It looks VERY orange to me.
oddly enough after seeing this thread i got three pixels together (from my friends) two XL's and one small to compare them.
The smaller pixel did have a very heavy orange glow compared to both the XL's, but no where close to this.
I have an RMA XL I'm not keeping and sending back, orangeness is identical to my current XL.
Howdy y'all, just to chime in on this for those who are still interested/find this via a search:
I first noticed this on my dad's refurbished xl some time ago, because mine (got it back when the phone first launched) didn't look anything like that.
Just today I got a refurbished xl from Google, and it has the same very orange nightlight.
So it seems that the refurbished ones have this problem, not sure why perhaps hardware issue?
As mentioned, a fix is to enable sRGB in dev option as that makes it look more Amber like it's supposed to, or just turn the nightlight intensity down.
Mainly though I'm curious what is up with this and why the refurbs are different?

Hey guys, got the phone for a few days.
already got burn ins from whatsapp. the white textbox is two times burned in (keyboard/without)
if u open up a dark grey picture u might see it as well.
just have seen it by an accident when opening "simple gallery", its base backround color was grey, so i found the burn ins.
i am not sure if all displays are affected by the burn ins, i will return mine :/
oh no. can u install aida 64, click on display, whats the panel id.
I've been using mine for almost 1 month and I have no image retention (btw it's image retention, it goes away . Only amoled's burn -in)
tianma td 4310.

Are you on MIUI or some custom rom?
If you are on a custom rom, go to display and then to live display and then to colors and from 100% go to 95% to all of them. This happened to tianma panels on Redmi Note 4 too on custom roms.
This also happens to every LG since G4. Low-quality LCD Panels.
There is nothing wrong with your phone , you can rest assured.

atm RR, so far the best rom i guess. but still the only one i tried. had the RMN4 as well, but never issues with the display (except yellow spot, soon warranty/repair)
i just hope for some aosp roms in the future like AEX and custom kernels
but atm the phone is pretty new on the market and we need to wait a little bit
Yeah, it would be nice to have selection of different ROMs.

actually it´s image retention, not a burn in. so it´s not good, but it seems to be okay.
i am not able to take a photo, cuz u would need a better camera for it.
i guess it depends on the apps that u use and how often.
if u want to see if u got it as well, you could try to download a simple grey picture.
for me grey/dark grey worked good to check it. then open it in fullscreen. u might see the buttons from the navbar slightly.
i´ve been using whatsapp a lot the last few hours, so i could see the white textbox.
atm i am on RR and i recently found out that u barely get max brightness on autobrightnes maxed out. after using max brightness (manual) it seemed to be better. dunno why may be on max brightnes, the pixel get "reset" better. i don´t know.
all in all. it´s okay for me and i guess if u got it, u can recalibrate it.
I installed aida 64 from playstore but I don´t get any panel info in "display"... where do you guys find that Info about panel manufacturer?
Everything is going to be alright. It's just a low-quality screen, nothing can be done except:
Go to display, live display, color tweak and tweak the colors. From 100% go to 95% and voila, everything is going to be normal. Tinama screens are pretty bad, you can go to the redmi note 4 forum and then look for image retention. There are a lot of topics about that and it seems that only tinama screens are affected.
tl;dr: nothing to be worried about. You probably wont have problems on MIUI because the screen is calibrated

Completely false, I have official MIUI 9.5.6.0, I have the phone for 2 days, it created image retention like crazy, god fing damn i didnt expect xiaomi to have such **** panels, so disappointed
@Kusie
Open Xiaomi dialer app and type *#*#6484#*#* and click "software version"
Tianma 4310 display as well. 7 days of usage. 22,75hr + of total SOT. Auto-brightness enabled. Contrast mode : high. Colours mode : standard. Mainly using tatatalk with night mode anabled , XDA labs with dark there as well and SimplePro for FB with white theme. Google keybord green theme. At late night hours auto-reading mode kicks in (100% set)
No image retention/tiny and barely visible navigation bar (or it's just placeboo).
Interesting. Some people here with the same panel face instant burn ins and some don't...
It has to be connected with color schemes of apps, which you are using or brightness levels, which you are mainly on

And why should we be forced to use ugly Cold mode? We lose color accuracy just by doing that, along with the screen having an unnatural blue hue which is also bad for the eyes, I want color accuracy not a screen looking like it's frosted
Hi,
i am on "Linageos 15.1" and today i saw that the color of the screen went to dirty. Before i had very good color representation and now it is like gray, no saturation, no big hue.
While rebooting the phone i saw the last Apps i was running. I can see the Statusbar while i am on bootloader-animation.
My phone runs for about 1,5 months and this issue appeared immediately from one second to another.
So there is no solution to get the display working as it should?
So i have to buy a new phone?
I got a replacement device b/c of the image retention. The display manufacturer is not Tianma anymore but Shenchao. The model number stays the same.
Hello everyone,
I have seen tech youtubers test the F3 and some mention that it will dimm the display quite a lot when gaming. (also another one did 4k video shooting for extended time and seen the same thing)
Do you think this is because the SD870 really "could" have an heat issue in the F3 and the software is protecting the AMOLED from damage due to overheating?
However I am still looking forward to receive mine, I just want to utilize the bright display at least during normal usage
Not sure what happens, I'm seeing the same stuff on diferent video reviews of Poco F3, the thing is, Poco X3 or Redmi K40 Pro usually go even beyond 10+ºC higher and do not suffer of such dimming issue. I'm guessing it's something software related.
Yes agreed, the SD888 devices get hotter and do not show this behavior.
Let's pray it's a software issue.
Could also be that the E4 Samsung panels really do need to derate because of their really high brightness. Even a 50% reduction would be as bright as my F1's screen at max. brightness
I am reading in local Malaysian forums they talk about comments in Xiaomi forum for k40 having such issue. I don't understand mandarin I am based on what they said its an issue with K40. Let's hope software upgrade could fix this issue.
Saw the same problems in some reviews yet a member of this forum who already has it had some issues with haptic feedback others have battery problems. I think I will buy another phone

Yeah don't get me wrong, only having a slightly noisy haptic feedback motor is not a bad result. When I bought my Oneplus 3 back in the day, the USB-C port was slightly offset, so the cable wouldn't fit snugly and dash charging wouldn't work. I've reported my problem with the haptic feedback motor on another forum and people seem to agree it is slightly noisy, but other than that the phone works like a charm for me (so far).
@Kom_zo That is reassuring to hear, glad you enjoy it
Maybe this was Xiaomi's design intent all along to have a more "audible" motor.
I will check it out once I have it here.
Did you experience any high heat and unintended dimming so far?
I have not had the chance to use my phone intensively yet, just some light browsing and Youtube/Netflix. I have however just made a video of the haptic feedback sound and I can tell you that this is not by design (the popping noise is coming from the phone, not the recording)
@Kom_zo Thanks for sharing!
Agreed, it definitely sounds not normal - somehow like a hollow "clicking".
Is it bearable or will you return it?
I have haptic feedback turned off by default, but my phone will vibrate for alarms/notifications and calls. As of right now it might just sound broken, but it is a moving part that could cause more damage to the internals of the device. I will try to swap it for a white model in a few days, but I think I will return it either way.

I agree with the statement from the Malaysian guys, it makes sense.
However there is a video from the same youtuber which shows Black Shark 4 vs F3 and the BS4 doesn't dimm the display.
Though I don't know which brand/type of amoled the BS4 uses.
Edit: Found it, watch from minute 2 onwards:
Is there any green tint with low brightness?
bassbounce said:

Shouldn't happen, since the F3 uses PWM for the amoled screen which eliminates color shift at low brightnesses.
This problem happen too when you off auto brightness ?
I think the tech youtube has set it to manual max. brightness.
I can only assume it will limit brightness at high temps regardless if you are on auto or manual.
I might get bashed for this but you can underclock and undervolt the GPU with KonaBess: https://github.com/xzr467706992/KonaBess
It's worth a shot if you don't game a lot, it'll likely not overheat causing the screen to dim as much.
I still feel the screen dimming will be reduced with the upcoming MIUI 12.5 update for the F3.
POCO said on a live stream that they are working on the dimming problem.

Excellent, thanks for sharing this information!
Hello everyone,
I got my device some time ago and wanted to highlight the things that rarely ever get mentioned by your average youtuber.
-) Yes, vibration motor noise is there.
But it feels really intentional, not like it is broken.
For me personally I don't mind it really, just wanted to share it since this is dicussed in this forum.
I don't have the "crackling" that has been mentioned, it feels more like when you set the alarm on an iPhone and rotate the hours/minutes wheel - satisfying.
-) Screen PWM'ing
The display is great, gets decently bright especially when viewing HDR content on YT.
Also the 120Hz is definitely a game changer, you can trust me on that.
What I however noticed coming from my F1 is the PWM.
Feels like they do 240-280Hz PWMing the brightness.
I feel like it is causing me headaches and sore eyes, but might just be the exhaustion after coming home from office work on Thursday's
Will see how it develops - my F1 has also PWM, but at around 4000Hz (!) which is definitely not noticeable.
Anyone of you have noticed the PWM? I might be an isolated case, even all high-end Samsungs's have 240Hz and no one complains ...
If you know a hack to enable DC dimming just shoot me a PM please
Hope I don't have to send it back because of this, would be really a shame.
-) Green tilt
Yes, I have noticed some green tilt at the upper half of the screen.
Only happens at really low brightnesses and with certain silver/grey'ish colors in dark mode with reading mode on.
But it is really minor, you really have to focus to make out a slight green shift.
That is no issue for me really, but wanted to highlight it because of the ongoing discussin.
Actually that was all.
The rest is great so far.
Extremely fast, premium build, nice AOD, battery is good so far, camera is more than enough for me and the sound quality is excellent.
If you want to me to test/check out something just let me know, as long as it doesn't involve ADB

It was stated about the K40 on Weibo by a Xiaomi official, but since it is the same phone as Poco F3 I guess the situation is no different.

Yeah so I have packed it up again and will send it back to Amazon.
Unfortunately the PWM does not go along with my eyes/brain.
But other than that, great device - can definitely recommend, just make sure you are not sensitive to PWM.
When does PWM kick in according to the brightness settings?
From what I have seen as soon as you are below 100%
PWM?

This should explain very well: https://www.oled-info.com/pulse-width-modulation-pwm-oled-displays
Can you please help me.. I don't know if my eyes are sensitive to pwm or not as I've always used an ips and I don't have the option of returning the phone, I used to get a headache behind my eyes while using my old pc for a long time, so does it relate to it or did you have the same problem?
Well yes, it could be - or you just were in front of the screen too long in general.
For me only my eyes start to burn when i have work in front of the pc all day, but no pain behind the eyes. This only happens with PWM'd OLEDs it seems.
What monitor have you been using with your pc?

samsung monitor b1930n, I used to get the pain after playing for long time. I then switched to a laptop (lenovo z50-70) and the frequency of the pain decreased a lot
I couldn't really find much information. If you have the chance just point a camera at the screen when set to medium/low brightness, if you see the flicker then your screen uses PWM.
To anyone wondering about PWM in the future, notebookcheck measured it at 490Hz. This should be fine for almost anyone.
My current phone Mi 9T has 240 and I did not even know it, so I'm good. Had me scared for a bit with the headaches and whatnot
This is a great phone and I am actually impressed by its display. It's so clear to the point that I enjoyed watching cricket matches on this phone. Great sounds as well, especially for the fact that it's not expensive.
Need assistance !
I'm planning to buy this phone since I'm done with my mi 10T .
Mi 10T having 1 issue which is the only reason i will let it go . The earpiece
has the ultrasonic technology which is annoying and unstable causing a lot of calling issues since there's no a proximity sensor . Even the WhatsApp voice notes having the same issues .
I have looked around for newer phone which i think poco F3 might be the one!
I have tried to look around if xiaomi still using that stupid technology init ! But no luck.
If ur facing proximity sensor issues please confirm since my birthday is coming on sept 18th and I will gify my self a new
Thanks
If you want to change because of the proximity sensor, give the F3 a wide berth. Whether the problem can ever be solved via software is written in the stars - and it is cloudy, very cloudy... I don't think Xiaomi will ever fix this issue.
