It's not software's problem, it's more hardware problem, exactlier touch screen problem, for this kind problem we can't do anything, just to send phone to repairing service, and to hope , problem will'not repeat, but from my expirience, just after 10-15 days of using, touch screen start to not responding, i scarried all htc diamonds after some period, became same, and i think this is generally problem of htc diamond 1st generation, maybe for htc diamond 2 , htc company solved this "strange" and big problem, cause this situation means, give money for nothing and problems!
Giving 2 years warranty is ****, if phone will start 3rd year of using with same problem, maybe is better to give 5 years of warrant , cause this problem
I don't know if you've fixed this but i had this very problem and it turned out if you wiped the screen over once then it would be okay.. strange i know but theres quick fix that worked for me.
I had the same problem, I send it to service and tey changed the display
I've same problem, the screen only works well when phone is cold, after warms up it shows the same sintoms
Got the same problem here - when the phone is cold its 99% ok, when it gets warm (or even hot due CPU heavy to flash websites), it starts with this touch screen "dance" (and empties the battery in maybe 2 hours by not going into sleep mode).
But I found out that somehow giving the lower screen border a "massage" does help. I guess there is some screen to board connection behind, which does not get 100% contact when the device is warm/hot.
last tuesday diamond came back from service with new screen....today the same problem

Well i tried to make some pressure but same problem. I can disassemble the phone and see if something is not in place, and also use some contact spray to improve connection. Did someone try something like that?
i had the same problem as you due to water damage from using it after a shower. sent it off for warranty and they sent me a refurbished one. sending it off again because it had bad whites and a dodgy centre button.
to bypass the screen alignment screen create a file called "welcome.not" and put it in the root directory of the phone. not in the internal storage, you must put it in the device storage.

I only discovered the touchscreen issue yesterday doing the test of the other thread. So, i would like to every z1 owner to answer this pool to know how bad things are and if we can try to find a solution, since i think Sony won't.
So, please answer the poll and post any useful information. I'll start.
My phone model is C6943, I currently don't use case and I'm using a screen protection. I can do the xperia touchscreen test without touching the phone body without problem and also doesn't have problem with pattern password.

Pool? I think you mean "poll"
My 6902 is completely screwed. At first I used a screen protector and the problem wasn't too bad. Then I removed it when I took the phone in to get another issue fixed and soon after that the problem got very bad. I was traveling so couldn't go back to the service center. Now it's a bit better, randomly works and randomly doesn't. When I was home in cold weather though it seemed a lot worse than it is now that I'm back in India where it's warm. Not sure if temperature is a factor, or could be conscience. But a few weeks ago it was so bad you couldn't type even a two letter word using Swype.
Also, I now have a part of my screen in the form of a horizontal line where touch doesn't work at all. No single touch and no drag. Completely dead. Taking it to the service center soon.
You should vote on the first option, then
Guys, check my post "News from whats is causing touch screen problem" to see if is your case!

It's not.
I got problem unlocking with patterns, scrolling pages and when I play some games after few minutes it stop working so I voted the first option. My phone is back to Sony, I hope they know what to do and at last it's Made in China.
Please, post if you use case and screen protections too. This could help understanding the problem.
Additional data : Z1 is being handled in a leather case, back and screen protector removed ( not the one with the logo, the plastic ones that makes your camera blurry )
Touchscreen problem seen in the game Alien Shooter, after some playing, the touch screen becomes less and less responsive ( i tap a button to shoot and use some onscreen joystick to move ) - both become unresponsive/less responsive as you play and the phone gathers some heat ( you can feel the touchscreen becoming hotter )
i have a simple tpu case, i had a bit of problem when playing all touch-based games (not ones with gyro like asphalt).
ever since i got the case it's better, i have the ASF and nillkin matte screen protector

I did not use any case just a chip screen protector. Anyway on a good healthy touch screen the screen protector should not influence the touch screen respond.
Hey guys, I have also this touchscreen issue, and I would appreciate if you give a feedback about warranty service, if sony accepted the problem and replaced a touchpanel or not, and also if the replaced touchscreen is better or not. I´m also thinking about sending it back for warranty repair.
I have also found that my phones touch screen is temperature sensitive, when it get cold or warm it just refuses to detect touch actions. Try it yourself put the phone into cold/hot water for 5 second, take it out, quickly clean the display from water and test the touchscreen. I first tought this behavior is normal and I didn´t cared until I started to play games. After 15minutes of playing the touchscreen bug every time appears. But also after a while its randomly disappears. So this thing is strange. (the bug appears identically also when I have my phone in a plastic case)

For me the warranty worked perfectly, i changed the phone 3 times until get a working one, i called Sony, discribed my problem and they changed for me, only 2 days for the change. BUT i recorded the problem and sent to them, so they accept the change.

Same here. I sent my phone back last week to the store where I bought it 2 months ago. They will send the phone to Sony Center but the time for repair or replace the device will not be 2 or 3 days but from 2 weeks to no eta. When the phone will come back to the store they will send the phone to me. I will post if the problem persist or not.
The problem is if they return a phone with the same problem.

They should be aware about this issue even on the new device so at this time they probably will check that but if they return a phone with the same problem, I will send it back again like many did. Someone had to replace the phone 3 times and I will do the same.
IYeah, you will be a long time without your phone though. I think I'll wait a bit since i rarely get the error and actually only when i try to reproduce it. How bad was yours?

I was able to reproduce the problem in many ways, Touch Screen Test, Opening the phone with Patterns, Scrolling Pages or with Launcher instead of switch the page it was opening the applications and at last when I was gaming at one point the touch stopped working and I had to wait, so this made my mind to send it back. On daily use was all ok but in some circumstances was frustrating.
i had the problem with cm11. and when I retored to stock then the problem was gone:S
I'm on stock and I got the problem.
Today for the first time I got the problem when writing on handrite. So I thought about using my phone warranty to get anotehr one. But it don't always fails when i do the method to reproduce it. So, how do you test if your new phone is working and how do you prove that it isn't? I mean what if i take the phone to warranty and it works?
And for you who already changed phone, it is working?

For me after the 3rd change is working now, here is what i did: i recorded the error and send it togheter with the phone. They saw the video and changed imediately.
Sent from my C6943 using xda app-developers app
Did youu made the method to reproduce and it didn't failed? For how long do you have the 3rd 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?
Hey guys, I've got some weird problem with air triggers for a while now..
The right trigger can be activated somehow without touching it specifically, but even if I tough the back panel of the device.. It's a bit hard to explain, but you can see it well in here:
https://photos.app.goo.gl/PZZar4gMKZdYChqdA
Is it a defect in the device? Cause it didn't happen when u got it
Bought it from giztop back in October.
No one encountered this problem?

I do sometimes have higher than normal sensitivity with my right air trigger, but it has not been as bad as what you show in your video.
My theory would be that something is getting in the way of the contacts in your air trigger. Are you able to get some compressed air and lightly blow into your headphone jack and shake the phone a bit to see if it comes loose and fixes the issue?
I encountered the same problem as you, and later sent it to the original factory to say it was a screen problem, because I bought the Tencent version and it took nearly 170 usd to change the entire screen panel.
Personally think that it is a quality problem, and some users of the standard version have encountered similar situations. The warranty should be sent to the original factory without charge.
Yes. I am also having the same issue. Need to check with service center.
Workaround solution. User dual partition. If you use it for PUBG or Freefire put the left partition to the empty place and the right partition to the appropriate button. Also make left partition touch as 1 times. This fixed the problem of miss triggering the button. Hope it works for you.
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.

(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

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!

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.
