[Q] Screen sensor bug. Please help

Hello,
After a month of using Note, I take the bug, that make device unusable. Touch screen press themselves, without of contacting of my fingers in the left bottom corner (near button 'z' on screen keyboard). And it become more and quickly.
But this problem have the "solve": when I connect the phone via usb and charge it, bug falling away. But if I disconnect, they return.
I try a lot of roms and kernels, but problem have not solved.
In the program "Multitouch vis test" i find that sensor take pressure in pixels placed 1108-1109 y and 95-120 x coords. So, maybe I can stop processing of touch sensor in that rect? How can I do that and can I do that at all?
Maybe charging let the screen sensor to be less sensable? Can I do this via programm (or kernel)?
And I don`t understand is it the problem with screen sensor or usb?(usb module is mush sheaper).
Sorry for long thread and bad English.
Thanks in advance, Giggsoff

No problem
Maybe you can try this and this

Thanks for links, but it don`t solve problem.
I record video, with my phone. May be it describe my problem

Just saw your video.
Looks really weird.
How long does this bug exist? From the beginning?

your sensor is very sensitive

I got that after month of using (two weeks ago) when playing "Order & Chaos Online", or maybe I start notice that. In the bottom right corner of screen (in landscape orientation) the button, that mean fire, was located. So I press it fast. But I get massages "select the target" when I don't press any key.
I was in hospital, when I notice problem, and it didn't falling away, when I connected the charge. But when I back home, connect there phone to charge it is disappeared. I mean, that it was result of my operations (I open the phone and clean, reinstall os), but it was only because I had connected the phone. Now, I try to use S-Pen, cause it lock touch screen, but it's hard and don't a way out. So I am going to return the phone. It's hard, because I am an international buyer - from Germany to Russia. Intresting thing - when I open my box I see, that on charge was words in Russia (maybe cause in it )
It's going crazy

Returning it back is a good solution, I think.
It's definitely a hardware problem.

Ok, thank you. I will do it next week. Sadly lose that amasing phone for a month or longer, but I shall have to do it.

When I had returned my old Galaxy S it just took 10 days until I got it back, so let's hope the best

S Pen not working

After I accidentally inserted the S Pen backwards, but later on managed to remove it successfully, the S Pen is not working.
It can still be detected, ie triggering Air Command or screen off memo, when I was removing it whilst it was stuck, but after it was removed it does not trigger the Air Command, and the worst part is it does not interact with the phone in anyway, not even as a stylus. :crying:
I only got it for a few days, and really hope you guys can help me solve this issue. If not I will send it for repairs and hopefully get it fixed for free or low cost.

Hi,
I have a similar problem after accitaly insert in wrong way.
The S pen work, but there is no detection anymore.
I had to remove every detection in settings, but I still have some notification about S pen removed.
(you can trigfer air commands by double click S pen bouton)
I would like to know if someone did repaire the sensor?

There is a switch inside the phone which you have broken by yanking out the pen after it was inserted the wrong way. There are videos on YouTube that explain it in detail.

Yes.
I would like to know if someone did repaire this switch, in a Samsung repair station?

spen working method
You can actually use the spen by going into settings, spen, and than turn off S pen power saver mode

My spen first began to get less and less responsive, i.e. I had to push hard for it to interact with the screen, and now it completely stopped interacting with the screen.
no idea dafuc is going on!

My phone won't detect my pen. It works though

I got mine stuck, removed it by inserting a bit of paper and now it doesn't work and it doesn't detect lol. fail.

First try to.change you tip with a spare one from the box. If the problem remains do a software reset . If none of this solve your problem then search with google for spen sensitivity. There is a metod to fix this problem.

Dual Screen and Extended Mode Aren't Working (AT&T Version)

Hello everyone,
I was wondering if anyone else is having trouble getting dual screen or extended mode to work? My Axon M has those two options greyed out whenever I open the second screen. I'm attaching pics to explain, but this has been happening on mine for a while now I've tried resetting my whole phone, waiting to see if it would “load” those two buttons, tried changing settings, etc. Nothing is working.... I feel like I wanted my money on this awful phone which hates me. I'm also gonna include a pic of my settings in case that helps. Thank you to anyone who could help me figure this out! I really appreciate it

I am having this issue as well. It just started to happen though. Both those modes were working before, Now only the mirror is working for me.
Edit:
I have fixed the issue. The sensor that detects if the phone is fully open was not activating. I opened the phone and pressed firmly on the back of the main body. I heard a small click(something snapping into place). I think the body was a bit lose and the sensor was not actuating because of this.

If only I thought to check this... Hopefully other people will find this info helpful at least

I have the same issue with recently received phone.
I tried to push on the back - but didn't get the click and didn't help me.
I found the same issue and half solution - using magnet by tapping on the back of main screen - where the sensor is.
https://community.zteusa.com/discussion/54349/extended-dual-mode-not-working
Again it's not permanent solution - but at least it helps to solve the problem for one session with the phone.

Hi!
I know is an old phone and an old tread, but has anybody found a solution besides the magnet thing?
I have the same problem and It's kinda annoying having to carry a magnet with me for the phone
is there a way or an app to make the phone believe its always unfold, so i can just switch modes ?

(N9208) Tune touch sensitivity without rooting the phone?

Hello, I'm a junior member here, I learned a lot from XDA as I read many threads but only have posted a bit.
My Note5 has been showing touchscreen malfunctions for a while, nowadays I'm using the S-pen. The first time I realized I tried to wipe the cache, and it didn't work. I booted into safe mode but it didn't fix it. I realized it was a hardware related thing. Then I tried to remove the screen protector, it did work, but not much later it happened again. I cleaned my screen and it worked (and start malfunctioning again minutes later).
I concluded that the oil from my finger was the problem, but unlike any other phones I've had, the touch begins to malfunction just because of a very tiny amount of grease build up.
(for example, if there's a small build up on the 'A' key on the keyboard, whenever I touch other areas, the 'A' key will also recieve touch input.)
I think tuning the touch sensitivity will help. So I asked for help here.
Was my conclusion wrong or is there any solution that requires no rooting?

Nice, it works! But may I know why did it happen? Perhaps I can prevent it in the future. What happened?
(Update) The screen malfunctioned again. I tried to update the touchscreen firmware again and nothing happened. I was thinking wether flashing a custom kernel and ROM would fix this or not, should I?

Replace the phone, could be the screen or the motherboard. Don't bother fixing it.

The weird part is it does work perfectly sometimes but most other time, it doesn't. I'm going to do a factory reset tonight to see if it works or not, or to decide wether I should flash a new ROM or not.
In my place here, a nearby retail store is willing to buy my Note5 for around $130, pretty sad to know. I love the S-pen but can't afford the Note 9 nor the Note 8. Should I buy a Samsung tablet with an S-pen instead?(it's currently on 25% discount).
Update: Is it a coincidence if the touch is problematic during heavy task (e.g. multitasking, running demanding apps, or playing games) and working fine during standby or light tasks?

How To Fix Samsung Galaxy Note 9 Screen Is Green

Problem: Samsung galaxy note 9 screen started flickering green occasionally for about a week then after that it went completely green and could barely see anything on the device until it just went completely black screen then green again.
https://www.sammobile.com/news/more-users-facing-green-tint-display-issues-different-galaxy-devices/
I have seen a large number of posts posted on other websites, and many users sent to the Samsung community, but the posts were deleted by the community administrator. This is a global error! I have lost my patience with Samsung and called the after-sales customer service. The customer service only asked me to take the after-sales test. Modern people's life is almost inseparable from the mobile phone. Now my mobile phone display is almost unusable. This is Samsung's own wrong firmware. As a result, after I updated the October patch, the error was not fixed! My work life has been affected! Samsung has not yet acknowledged the problem and has not actively responded to it. Samsung Note 7 has experienced a battery explosion, and now the screen of Note 9 starts to flash green. Samsung is really bad! Even so, the Samsung community manager deleted a lot of feedback about the screen turning green and flashing. I think Samsung’s attitude is problematic! Samsung exploded in note 7 and lost some fans. Now Samsung is not actively fixing the issue of the screen turning green! Caused me to dislike Samsung!

From what I've heard the screen need to be replaced. Buggy software update caused it to damage but samsung is playing dumb by denying it. The screen replacement would cost more than half of the phone's price.

Yes, I went to the after-sales service to confirm, the screen needs to be replaced! Users need to pay for Samsung's wrong firmware!
I will never buy anything from Samsung again!

(Procedure S9 and note9 but should work on all with always display)
It's a software problem.
I show you.
Activate always on display, choose "home button and clock" and "then tap to show".
Exit settings.
Turn off the phone with the physical button on the side, and turn it back on in the same way after two seconds.
Now the screen is green.
Now turn off the phone with the physical key.
Touch the screen, the clock appears and under the virtual key, turn on the phone with the virtual key.
Now everything is fine.
Give it a try, if it works write it here.
Because it would be immoral to spend $ 250 to repair a phone that is only a software problem ..

The problem is that I have a broken screen and then it always stays green, or it is not the screen, as in this case and if you turn it on in one way it is green and if you turn it on in another it is fine. perhaps it is a case of planned obsolescence

This didn't work. It seems a new screen is required. This will be my last samsung for sure... Fisrt, the bad ROM with the Note 4, now this.

I have this issue with my Samsung Note 9. I searched the internet and found this post. I followed exactly what was said here and this definitely works. It solved my issue., no more green tinted screen. Now I just need to get out of the habit of using the physical button on the side of the phone for turning "on" my phone. Hopefully Samsung will fix this issue soon so we can use the phone as intended, but until then, thank you for helpful information and finding a solution to the problem.

It's a great solution. To all those who are saying that it's a hardware issue, it's not. Samsung messed it up and the service centre guys are brainless and uneducated enough to not know that.
I would like to propose a better solution - instead of tap to show and then force clicking the home button, you can set always on to permanently show and choose the home button option. That way, you will only have to press the home button and won't have to go for the extra procedures.
Again, this method is just a modification to the original hack and kudos to the editor for thinking that way!

Worked for me. Thank you!

This is not only a software issue.
Only solution to change your display.

Rule #1 if your OS is fast, stable and fulfilling its mission...
Do Not Update!
This goes double for carrier phones. AT&T for example will wreck your phone with their later updates.
With Pie and above security isn't an issue unless you do something stupid. Don't get sucker in by scare hype.
Always redundantly backup critical data to at least 2 hdds and always be ready to reload. Reload if you can't resolve a malware issue asap. Cover your ass...ets
Your Sammy will run well for many years if you leave it be

defilante's method worked for me. However, if I am on the phone and need to use another app after the screen has gone to sleep, I have a green screen again. In other words, doing phone calls, I can't access any other app and see it. Once the call is over I used the method mentioned and clear screen again.​

Not a Note 9 or S 9 but I got the same issue with Note 10 plus 7-6 days ago and I couldn’t go to a service centre to fix it. now the green screen issue is gone. I don't know how but it's totally gone. I just used the device usually with that green screen error around 4 - 5 hours per day (but stopped all the heavy works and reduced screen brightness too.) and yesterday evening I saw the green screen had gone when I unlocked phone. so my advice is just give it some time to check if it'll be restored and fixed.
In case if it's fixed don't use the phone heavily as you did before (If you've used heavily) and use it under low brightness (don't maximise it).

I got the same issue one fine day and even the device reset option did not work for me.
THe only option which works is to keep the "Always on" screen activated and unlock through it. Anybody saying ITS A HARDWARE ISSUE, must be able to answer that why the hardware works fine if unlocked via Always on screen and not when unlocked normally.
Its a temporary measure and the problem is very irksome. One side I have to live with an additional battery drain of Always On screen now. And on the other side, the issue still persists if I get a call from someone as the screen is green and totally unreadable (especially under sunlight)
Did anyone try a Custom ROM and got this issue fixed? I am going to try custom rom only for this issue and thought of checking here just in case.
When people buy sammy phones at sucha high price, the expected device life has to be much much more compared to Chinese phones, else why pay such high premiums.

So the display completely normal when you run it like this? If you have the tap on AOD option, it should use little battery.
Try not using the lock screen at all. I double tap on/off always.
With its millions of semiconductors throughout it could still be a hardware issue. Ever wonder what happens when just one fails?
You maybe bypassing the damaged pathway...

I dont have enough knowledge on this subject to either completely agree or disagree with you.
Let me try few custom ROMs and old official firmware versions and then I will be able to say anything conclusively.

If the original stock firmware doesn't function as it once did, then the hardware state has changed.
If you can avoid using that pathway with different firmware than the defect is irrelevant.
It's rather interesting but it's just a guess on my part.
Are there any redundant pathways? Self healing for any circuits other than flash memory cells? Don't know but I suspect not.
Pretty amazing these devices last as long as they do.

My wife's Note 9 has had this problem since mid-2021. I bought her a Pixel 6 as a replacement. Always-on display indeed works but as you said, once you're on a phone call, you in trouble again. Amazing Samsung has totally ignored this - I guess the phone is old enough to pretend like this problem doesn't exist.

Adding my experience to the mix. Bought my unlocked Note 9 (512GB) the week it was released. Never had a problem until 2-3 months ago. Started having an issue with an app not recognizing that it was paid for so I did a factory reset for the first time since I purchased the phone. After the reset, boom, green screen just like everyone else and the same workarounds work as well. Doesn't feel like a hardware issue and Samsung/UBreakiFix have been no help. Samsung really needs to step up quick because I'm getting ready to go out and buy an iPhone 13 Pro Max.
