Note 9 screen issue! - Samsung Galaxy Note 9 Questions & Answers

hello..
As all we know about screen discoloration issue on Note 9 since March... I was able to solve it through AOD solution before the latest security update which is July update.. now after the update the problem is permanent and really annoying ?
So is there any way to just go back a little bit and delete the last patch or downgrade it or something like that ?
Thanks ?

Using oled saver
Same issue here. Before the update, it also worked by taking a selfie with the flash on. Not working since the last update. Final solution was to use the OledSaver App to make the phone atleast uasble.

I heard that it may damage the display if it used for a long time so I'm not sure

Samsung galaxy note 8 sensors not working

Hello,
My Galaxy Note 8 GT-N950F sensors are not working. Proximity, heart rate, barometer, rotation, iris scanner and other sensors are not working.
Any HELP please !
Happened today, i saw some people got same issues since the new Android 8.0 updates.
ANYONE HELP ME PLEASE!!!
Did you check sensors from test menu:
*#0*# (in phone/dialer)?
Yes already dialed. Nothing is working. Download CPU-Z too, nothing is working. Hard reset too. Same issues.
Any other solution?

Same thing happened to a friend on 7.1.1 with a 950F.
He had to claim warranty on it since we tried multiple firmware's, but nothing brought the sensors back.

Go to Samsung ASAP to get it fixed under warranty
I've claimed the warranty, still waiting for the phone
Will I lose all my stuff on the phone? Or will It be the same?

Chances are you won't get your exact phone back. But a refurbed one. Just use samsung backup app. Works pretty well. And of course factory reset afterwards.
I'm having the same issue with my device past few days (Exynos Chip)
My reply was here.

I haven't experienced it myself, but previous posts in the thread indicate a hardware problem... If you already flashed the latest stock firmware with full wipe and it's still not working, then it seems to confirm that hardware issue.

Can you find those posts you mentioned and link them here? If it's software related then flashing the latest stock firmware should help. Did you do a full wipe and used csc instead of home_csc in Odin (along with the other firmware files)?

i'm really sorry but can not link them because i saw so many websites and can't remember and yeah i flashed all files with odin but this also don't work any other solution and also saw a video on youtube about xiaomi device sensors stoped after software update
As some buddies stated before, take your device to claim warranty, that's it
I'm getting GPS errors lately, very very weak satellite signals even under 100% sky, I don't know if they are related. Ugh, so much for a $1000 phone
Echoing the responses of others. I would take your device to either the retailer or a Samsung Service Center. As this is probably a motherboard issue.
Facing same issue, all sensors not working. Will be going to care center tomorrow.
I had this problem after I had my phone led screen repaired (under warranty at samsung). Lucky I check everything after every repair.
They took the phone back and got it fixed in 5 minutes. Said the tech forgot to flash in some files.no idea what files but all they did was change the screen and battery.

Weird Dark Blotches on screen?

Hello! For some reason my phone has these weird dark spots that jump around whenever there's something dark on my phone (Reddit dark mode, twitter, discord, dark spots on youtube/netflix) and I tried to use a screen recorder to capture it but it doesn't show up on the video, so I assume I just have a faulty screen? Or is this a bug with Android Pie? I only got the phone a few days ago, no drops or thuds on it.
It's a known issue that was introduced in the February security update.

Well, I guess I'm happy my screen isn't broken but this also means I don't know how to fix it.. Have they announced that they know this? Once I update my phone to pie (The day I got it sadly) I've noticed so many issues with it, and I can't go back to Oreo :/
People have reported it but no official response from Xiaomi yet. We'll have to wait and see if the March security update fixes it.

Thanks for these details. I almost accepted the update but declined.
It's going to take a lot for me to purchase a Mi A3. Quality control on this device is horrid.

mi 9 multi touch problem

My mi 9 seems to be able to only detect 1 finger. Completely wiped phone and problem still persist. Anyone with same issue or able to fix issue?
I have the same problem. Have you found any solution?
youtube.com/watch?v=dLa-oHLig7U
I have that same problem. Could you help
Happened the same issue to my Mi9. Multi touch was working normally but suddenly it stopped working while I was zooming on a web page. Then I made a factory reset but still didn't work. Today I updated to Miui 12 hopping the problem would be solved but still no success. I think this bug is related to Android 10 as I saw elsewhere someone rolled back to Miui 10/Android 9 and things got to normal. On the other hand this is not a hardware failure for sure since multi touch keeps working normally on apps running in game turbo mode.
So, has anyone found how to kill this annoying bug?
Thanks for any help.
ive been searching everywhere how to fix this. i already email xiaomi about this issue. still didnt find clue how to fix this bug. still hoping that xiaomi will fix this issue.
This issue is a shame for Xiaomi!
As far as I know the only solution is to downgrade to Miui10 and stuck on this version or take the risk to upgrade to Miui11 (not recommended for obvious reasons) or the fresh new Miui12. So far I've been using the "turbo game" thing to workaround the bug. I had to install some alternative apps from Google Play (such as Chrome Beta, other gallery app, Google Maps Go...) to use instead of the stock apps so I can use them with "turbo" and get pinch to zoom working. This is not the best way to solve the issue -- the ideal is to get multi touch back working again without the need to resort to any tricks -- however it works very well. Maybe one of these days I'll get some patience to setup the good old Miui10 again...
i also have this ghost touch on the upper part of the screen. it came same time as the multi touch issue. it cant even fix by game turbo. i cant even play games normally like moba or fps game. i dont know if its just me have this ghost touch issue. its a big shame for xiaomi flagship phone?
No news about this issue? Everything works fine with Pixel Experience in my MI9 but multitouch. I remmember I solved another problem (auto-rotate didn't work for the display) and I solved it flashing only last version of "persist.img".
Same here bro!
I bought my Mi 9 in February and everything worked well. I also upgraded to MIUI 12 with no problems at all, then suddenly multitouch stopped working.
If I flash Pixel Experience will the problem be solved?

No way, Installing PE doesn't solve the problem.
I'm going to try it with new kernels and FWs.

Try to flash MIUI 10... I read somewhere it should work, because MIUI 10 is built on Android 9, which doesn't have this issue
same i have this issue, i tried miflash. the only workaround are miui 10 and game turbo method.
also i have this nonresponsive part of the upper screen, right where most game analog button placed. idk if this "dead touch" is connected to this multitouch issue
This was the first and probably the last Xiomi I bought. Back to iOS. Bought a second hand iPhone 11 in mint condition. Working rock solid! Crap Mi9!!!

Have the same problem here!!!
Upper screen DEAD
Annoying ghost touch on upper screen
Have to type multiple times because It keeps ghost touching...
Can't sell the phone, because of these issues...
Miss my Galaxy note
Is there a fix to this issue now? GameTurbo enhances the touch so that multitouch works. There must be a fix to this.

Samsung Note 9 - Display Discoloration & Overheating

Who else are facing the same problem ?
1)Initially, when I unlock phone by pressing power button the display was changed to dim colour(mostly yellowish) and with horizontal lines displayed when the brightness is below 50%. After tried with multiple times pressing on power button the display came back to normal.
2) Next stage, it's not solved with power button. I have to keep my phone aside for some time to get back to normal display. It's been 15 to 20 min then.
3) Now, I would get normal display only in morning. Else, I need to keep my phone idle without touching for at least 4 to 5 hours. I've also changed screen power off time from 30 Sec to 10 Minutes. So that my screen wont turn off and I can keep the normal display. If I forgot to use or kept aside more than 10 min then my screen would go off and display would gone again and irritation starts with that discoloration problem..
4) If display changes to yellowish to reduce the horizontal lines problem I need to increase the brightness to 80 or 85% but this causing my phone with another problem "heating issue"
Samsung haven't responded on this issue yet, how could we bring up the issue and get the proper resolution from Samsung.
This happened after last March update installation?
What note 9 do you have?
Probably not a hardware fault if it happened after recent software update.
A number of note9 affected although samsung seems to disagree at the moment.
Hello,
I also have a problem with the display after waking up with the POWER button. There are tinted colors distorted and some stripes like dim lines and slow refreshing. Everything started after updating to Android 10. In fact, when the display lights up incorrectly, it starts to heat up from the bottom. Putting the smartphone aside for a moment or cooling down causes the display to work correctly.
Workaround? I turned on Active Display and first knock to activate it, then the display lights up correctly and then I unlock the screen and use normally. It is known that battery consumption increases. Of course mine is Exynos.
hi guys,, i remember a similar experience sometime back.. try this. if u have turn on the proximity sensor i mean the advance feature where the phone screen doesn't turn on while in pocket , switch it off and restart the phone and see if the problem still exist.

whats the firmware version u are having now and phone model?
Try wiping the cache partition in Recovery Mode. If that doesn't work then back up your device and manually reinstall the OS back onto your device.
Im having the exact problem. I flash LineageOS and it worked by max brightness then back to auto. I installed brightness widget to max brightness and back to auto everytime I turn on screen.
This issue is popular after March update. I tried everythings you mentioned above, reset, flash new firmware, even April update, wipe cached, flash cooked rom, heat screen, turn off features, disable gpu overlay, etc... Samsung Vietnam guaranteed can fix with new screen but I'm out of warranty.
I dont have any issues us unlocked snapdragon xaa model on latest android 10 version.
Can we confirmed that a screen replacement fixes the display problem or is it still a software issue

No one knows what is the exact cause here, its noticed in many devices right after this March update but few are noticed months before. But, now the problem came to many users at same time. So its been brought up by many tech blogs, websites.

I'm having the exynos version too but with ITV (Italy) firmware ...never had this problem and now I'm on April's version after March's version.
This looks a little bit like what happened to the S5 years ago when after 1 and a half/ 2 and a half year's the screan began flickering, having green spots or lines, randomly didn't go on with low luminance settings since it completely died....a lot of people said on forum's that it was the screen and a replacement solves, but when it happened to me years ago the Samsung assistance center told me that it was another component (never told me what it was) causing the issue and once they changed it , they solved the problem.
So, after my experience with the S5, don't know what to think now for what is happening to some guys even if I think that this issue might depend with something happening after marchs update because for the too many people having it after the update, coincidences are not credible.

Yes, many people were facing this problem and how many times we have contacted the Samsung they are behaving like they just hearing the issue for the first time. Just created and posted the link in Members app and 67 members joined so far. Everyone having the display problem out of nowhere. All of them on out of warranty except one or two. Still members app floating with the display problem messages.
Display issue got noticed in S20 too but they immediately released the security patch and solved it. Don't know why they were silent on Note 9.

Black crush / gradient banding issue in samsung note 9

Hello community!
I recently bought a samsung note 9 out of the love towards the note series. But, after 2-3 weeks of usage I started noticing that there are some issues in displaying darker shades of black. The gradients of blacks are not shown properly. Instead, bands are formed in different shades of black. I searched internet and found that it is called black crush. My display is perfectly fine and it is appears like some firmware/software problem rather than a hardware issue. I also saw many people complaining about the same issue with samsung premium phones like S9+, Note 8/9 etc. But it is very surprising that there is no result for black crush or gradient banding in xda forum for note 9.
Please help me here. I wanna know if this is an issue of my piece only or is there anyone with the same issue. (Do check your phone twice before saying no. You might miss to notice it). It is so sad that a premium phone like note 9 is having an issue like this. I also read that even the advanced note 10 also face this problem. So even an update sounds foolish. The black crush isssue is really annoying. Once we notice it, we'll see it everywhere and we cant unsee.
I can't put screenshot to explain as it is a processing problem. You can search google to understand black crush or I can take a picture, if needed, of my display showing it.
If the problem really exists, I think it is high time for Samsung to have a look at it.

Im in the latest security patch (1st September 2020). Is there anyway to get rid of the black crush problem? Would it help if I try installing a custom rom?
I can't tell if custom rom could fix your problem or not but those with display discoloration issue mentioned that their problem haven't go away with newer security patch(Aug/Sep).
If you've no plan in using samsung pay, you could try custom rom but rooting will break this function forever. There are workaround for other functions(at least in rooted mode), but not for samsung pay.

I was thinking about installing another OS. But, I'm not feeling to do it, as rooting permanently trip Knox. Do you know if the black crush issue is a h/w or s/w problem? Is there any fix for this? Will rolling back the OS to any previous version can help removing it?
I don't know if it's s/w or h/w but most people with display discoloration issue(not sure if similar as yours?) said s/w. Better just wait for newer firmware base. Those security patches probably with old bootloader/base that's why the screen issue persists.

It appears to be a software issue for me too, rather than a hardware one. Thanks for your advice. I'm gonna take it and wait for some time for an update from samsung, without unlocking the bootloader.
