This. Is. P8. Lite. ALE. L21. Enjoy.....(and g'd l'ck) - P8lite General

this is huawei.
P8 lite.
ALE-L21.
Alice model, of 2015.
I think it's a part of "what it has been given to me"
in a way, where andro5 has been replaced by ungoogled lineage14(andro7)
but software even a bit crappy is not the culprit here.
Culprit is, well, yes there is to be a culprit in this situation
phone is locked, 4G/LTE working well, low than 6°C outside.
the culprit is not the software ; not the ambient temperature.
Culprit is the hardware, where even with the "backcase", I mean,
the stock backcase, the one you remove only to change the battery,
branded huawei, clipped to the phone. Even with that one removed,
so that means you can see the electronics components at the rear of
the device, because the "standard backcase" in transparent plastic
is transparent, even with only two milimeters of thing plastic, it..
overheat. And that's the overheating the most impressive for mobile
brands.
It reminds me the overheating problem crossed on large number of hp
large public laptops, solt with amd/nvidia, where air conditionning is
a total disaster, whom comes easily to what IT nerds (including me), calls
the artefacts problem, where a "reballing" process have to be done,
except if you prefer doing it with a common heat (I dont encourage it,
regarding the toxic criteria of those raw materials, if you use the oven
to eat then..), it might work for few months anyway.
But here, it's not really the screen in the graphical part of the issue :
the screen shows something anyway, the display is on ; the thing is,
the touchscreen, in the tactical part of it, is totally "dynamited" by
the hot (or cold) part of the hardware. I dont know why. It's a mystery :
on several lineageos, but obviously on the stock android ROM, it have
this effect. That means some part of the hardware is a bad quality (even
very bad), where it makes, when temperature is near zero degrees (celcius)
or even after running a bit, with phone in your pocket, in a twenty'degrees
(still celcius) common summer, well the touchscreen is so excited that..
it send data, like if you where touching your phone, everytime, in all senses.
that's why I really dont like this model (not only, see ABC mark follow..]
so that's the effect of the touchscreen issue, I let you enjoy this

in addition:
A/ wifi problems : sometimes, when I airplane mode or just turn off wifi, it's just impossible to get it on again, I have to completely restart the phone. I don't do anything specific, except Im out of rang or just turn it off from menu or airplane mode. But very often it can't be turned on back if I don't reboot the phone
B/ power, restart..
1 of 10 attempts of just shutdown the phone by using the button then menu works. 9 of 10 attemps it's ust shows the "shutting down" screen forever, last time it took 2 hours of "shutting down" but did not. Had to salvage restart it by holding ten seconds the power button.
Btw, if the P8Lite running LOS14 is plugged in USB, just know that it cant stay powered of for a long times, after ten minutes lineageos just power on automatically, even if you dont touch the phone
Btw the only way to poweroff the phone is to restart it (powerof button almost never works), then at encryption-unlocking code screen to power it off normally, but if you let it on the usb cable it will automatically poweron back after a while.
C/ unlock screen problems :
sometimes when the phone is on and locked, I just try to enter my PIN. numbers works. Then to validate. Then it freeze. Then it's very funny to see that it's doing nothing anymore, that only emergency button and dialpad for unlocking works but not the validate code button one : and even if the button of number works, it doesnt mark them on the PIN code field! As for the wifi problem, the only way to solve this looks like to poweroff and reboot the phone..
D/ just see few days ago the camera works, front and rear, but can't record videos..
In addition, just know I use on daily life twilight to get my eyes in a better way..dunno if it can cause issues.

HELP!! my screen works....but it doesnt....

ok guys and gals, heres one for you. i know im a noob but this one has got me stumped and i cant for the life of me find anything in this or any forum or even google. i have the tilt. just flashed a cooked rom for the first time several weeks ago thanks to everyone on here and all the FAQs and stickies. (to any other noob, all the info is out there!!!!! dont be lazy!!! SEARCH AND READ YOUR HEART OUT!!!!) anyway, im running Witscheys latest 6.5 rom build 23071 HSPL 3.34 w/ radio 1.70.19.09. ive been tweakin it pretty much every day tryin to get it to the way i want.
well im so close to finishing and the the screen suddenly decided to randomly not respond to my touch. the buttons were the only way to control the phone. even after numerous soft resets. then it would decide to start responding. so i was doing some research and tried a couple diff methods of fixing "screen freezes" (but i dont think its a "screen freeze" as it worked fine with the use of the buttons) finally found a post in the thread for the room that read:

I had that same problem. Need to change the cache settings in Advanced Config. The filesystem cache defaults to 512kb, so I set it to auto and it doesn't freeze anymore. I also turned up the glyph cache to 32kb. Between the two, the phone interface runs fast and smooth.
so i tried that and it still didnt fix it. then i decided to just do a hard reset and install one app a day at a time (all the ones i had before the hard reset) to see if one of them was casing it. well after the hard reset i didnt notice the problem anymore. i was stoked. now all i needed to do was figure out which app was giving me trouble. WELL about 10 min later when i was texting my friends as usuall, my phone recieved a message but the screen was black. so i slid it open (wake on slide) and the screen turned on. replied to my buddy,closed the lid and the screen went black..... WTF? slid it open, screen on. closed, screen black.... and so forth. this is the way it has been since yesterday. even tried two more hard resets with no change.
NOW HERES THE WEIRD PART!!! if i slide it open JUST A LITTLE very slowly, the backlight turns on barely. just enuf to see the today screen but its very very dim. its as if there is a bad connection. but the screen is in portrait mode like it should be. if i open it fast the backlight turns on, screen shows portrait, then switches to landscape like it should. close it, it goes black but i know it switches back cuz the next time i open it, i can see it change again.
EVEN WEIRDER--- if open landscape, get into an app or program such as contacts where i can flick to scroll, ill close the lid, immediately flick the screen, open lid and low and behold my friends are just scrollin by!!!! the damn screen is responsive but there is no backlight!!! so to test i plugged into my laptop, activated mymobiler, and EVERYTHING works like it should when i touch the screen, use the buttons, open close the lid. it all shows up on my laptop. but the damn screen is still black when lid is closed. so i can literally look at my laptop and touch the black screen on my tilt and controll it!! WHY IS THE BACKLIGHT SHUTTING OFF WHEN ITS CLOSED!!!!???
so then i decided to tear the damn phone completely apart about 2 hours ago, check all connections, and clean all the dust. all connections checked out fine, put it back together and still have the problem. i know there is a magnet and sensor that tells the screen when to rotate when the screen is opened or closed but its obviously working cuz it will rotate the screen. my guess was that some kind of registry entry has been changed somehow. but then i realized thats not it because the hard resets didnt fix it. now im thinking hardware...... IM SO SORRY THIS POST IS SOOOOOO LOOOONNNNGGG but i dont know what else to do. phone was working great up until yesterday and i cant have this!!! has anyone had this problem with this or any other device or even know which direction to point me in??? PLEASE HELP!!! thanks in advance for any replies!!! the quicker ther better
I think your flat cable is broken. Doesn't make connection when closed (no backlight), barely connects when opened (backlight on).
So I think you need a new flat cable...
I agree with blueflame... I think it has nothing to do withthe rom flash.. it sounds like your ribbon cable is "Starting" to go.. unfortunatly it will only get worse where it wont; read you memory card, and evenutally your Sim card as well (speaking from experiance here).... If you are handy with tools, you can try to but a new one yourself and install it... But there are also some shops aroudnthe world, aswell and some members here who may be able to fix it for you... for a price (and not, I am not one of them)... Sorry for the bad news bud.. but I personally would rather knwo that than hard resettign 100 times and nrto beign able to figure out the problem...
hey. thanks for the fast replies! thats not exactly what i wanted to hear but like Teej said, its better to know than messing around with something else. now by flat cable are you reffering to the biggest ribbon cable inside the phone that connects the screen half of the phone to the keyboard half? Or the connector that comes directly out of the screen itself (meaning i buy a new screen and install and all is well) or is it another cable? but i think those are the only two that have anything to do with the screen other then the one for the sensor/magnet. here is a photo to help point out which ones. i have the manual so i can grab more photos if needed. thanks again for the help so far. good stuff. we are getting somewhere!!

[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

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

Auto power-on driving me nuts

Whenever I leave the house, I unplug my Note to take it along but every time, before I stick it in my shirt pocket I have to turn it off first. That's because it on by itself just because I removed the charging cable. At first I thought this would just be a minor annoyance, but by the time I've needlessly turned off the thing a few hundred times the damn thing really starts to annoy me. And it's even worse when I try to charge it in my car because every time I turn the key one way or another I have to turn the phone off yet again. It's a bit more difficult because I have one of those silicon rubber protector things so it takes a little longer to find the off button. But I like the protection that this cover provides. I suppose I could just wait for the timeout (which I like at 5 minutes), but that would waste some battery power that I may need later. Plus it just annoys me if it is on when I'm not using it. (Actually it is the same problem when I plug it in to the charger as well!). So who decided on this ridiculous behavior? If it is an Android thing - shame on Google. If it is a Samsung thing - shame on them. (If so I might even switch phones ... although I haven't heard of another phone that can compete with the Note). Or is it just a quirk of my ROM? (I only used GB for an hour or so, and didn't have time to observe this behavior or not - then I flashed PA which I have been using ever since.) I love this ROM although I would switch in an instant if I could get rid of my only real annoyance with this phone.

First the silicon protector that you put in your phone because it cover also the power when put it in your pocket it keeps triggering it, its like a hair trigger.
Of course when you plug the charger it will trigger the screen to on.
Why dont you just adjust the screen time out to one minute.
I dont have this problem but anyway, a quick fix would be to use Tasker which lets you easily automate everything in your phone

That would result in about as many needless and annoying presses of the power button as it turned off when I didn't want it to.

That would be great if Tasker could turn it off again for me when it was turned on automatically. I took a quick look at the hardware events that tasker can act on such as:
Display: Off/On/Unlocked
File: File Closed/Deleted/Modified/Moved/Opened/Attributes Changed
Hardware: Camera Button, Search Button Long-Press, Card Mounted/Removed/Unmounted
Misc: Gesture, Shake
Phone: Missed Call, Phone Idle/Offhook/Ringing, Received Text, SMS Send Success/Failure
Power: Battery Changed/Full/Low/Overheating
System: Device Boot, Device Shutdown, Device Storage Low, Locale Changed, New/Removed/Updated Package, Wallpaper Changed
However being plugged in or out is not in this list. So how can it be done?
~Paul
I'd like to know too.
I can understand "screen on when charging cable plugged in". But its annoying as hell to have the screen on when charging cable is removed. Since 95% of the time it's going right into my pocket.
press the power button and screen will go of...

let's understand this better:
Your phone is off and turns on upon disconnected from the charger, or it is already on, but you don't want the screen to lighten up when you disconnect?
If it's the first case, that's weird...mine never auto initiates...If the second case, really don't know what you could do.
If it's the first scenario, maybe a factory reset? But beware of the brick bug and flash a safe kernel first.

Hey there Paul,
Man, that is one hell of an issue you have.
Anyway, I don't have much to advice you as I'm not using PA rom on my Note(for the moment ), but hey.. you said it for yourself that you were not able to test it thoroughly your Note before in GB right? only about an hour before flashing to PA?..hmm... logical advice I guess on my end would be to try to flash it back to GB again and observe it for 1 complete day to see if the same issue still occurs.
By the way.. you have a very sensitive Note there bud.
Again, going back to GB is the only way(if you we're to ask me), to confirm if the 'sensitivity' is still there or not anymore.
P.S. I might suggest to you to take out that screen rubber protector in the meantime also. Just use it 'naked' for a day on stock GB.
See how it goes after.
Cheers!

It's the 1st case. My phone is off and charging. I remove the charging cord and the screen just turns on despite the fact that I have not hit the power button - or any button for that matter.
I think it is more weird that you don't have this problem than the fact that I do. I've googled this and found many people complaining about it, but no explanations anywhere why it works this crazy way or how to fix it. And "Noodled24" who responded to my post above is yet one more person who is annoyed by this problem. I suspect there are thousands more (maybe even millions?), most of whom don't vocalize their annoyance.
BTW I'm being pretty glib with my use of the word "off". I'm really just referring to "screen off" - i.e. what happens when you briefly press the power button. I'm aware that this is not really off in the more conventional sense. If I power down using the power button long press, then no ... I don't have any problem with it turning on all by itself. So if this is part of the confusion, sorry about that. In fact, like most phone users, I almost never do a reboot (true power off) unless something goes wrong with the phone.
And recently I've found some people complaining about this problem regarding other Android devices, so I no longer think that this is a problem just with the Note, or just with the particular rom that I am using. Although I still don't know how wide spread the problem is.

I don't think my Note is "sensitive". I've very carefully removed the power cord many times (even without the rubber cover) to be sure that I am not touching the screen or any button whatsoever. And BTW the problem does not happen 90% or 99% or even 99.9% of the time. No - as far as I can tell the problem occurs 100% of the time!. So I wouldn't call my device "sensitive". I would just say that it has been improperly programmed to work in this bizarre fashion. Usually such programming mistakes can be fixed, which of course is why I have posted to this forum.
I don't think going back to GB will solve the problem. I think the same problem happened, although I can't be sure since as I mentioned before I didn't use GB for long before flashing to ICS (PA). However even if it did solve the problem, IMO going that far backwards wouldn't be a very attractive solution.
~Paul
So you don't have to go back to GB......screen turns on when unplugging my stock rooted GB. I think that is the normal behavior.
I agree, unplugging shouldn't turn on the screen, but Google does lots of things that don't make sense in real life usage.

[Q] Droid 4 possessed / erratic touchscreen behaviour

Since the last few days I've been getting some strange issues with my touchscreen. Sometimes parts of the screen (or the full screen) do not respond, and even the softbuttons are affected. When I take the phone out of my pocket, it either responds normally (I use pattern lock) or tries to use the emergency dialer or emergency contacts, and sometimes even tries to call a number from the emergency dialer (number 2 and luckily not 112..)
When in the launcher, it sometimes opens an app (like my calendar) and slowly scrolls either sideways or vertically. Turning the screen off and on again once or twice usually solves it for a (short) while.
I've already read some threads about it and ruled out the following causes:
The phone is not connected to any charger when this happens.
It still happens after cleaning the screen (just with a cloth, no liquids)
It still happens after disabling CPU Tuner. I didn't overlock the system, but used some custom power settings and different governors which apparently can also affect this behaviour.
The battery is still original since nowadays I prefer to use external chargers instead of buying a big battery for every new phone
The only things that changed recently are:
I installed the OwnCloud app, but that doesn't seem related.
We moved to another office building, in which the carpet generates more static electricity.
I gained some weight which may put a bit more pressure in my pant pockets than before
It started happening a few days ago, after using the .215 ICS leak for a few weeks without issue. I seem to get the problem less at home than I do at work, which makes me think it's either the static electricity or CPU governor (since battery percentage is lower by the time I get home again, so it might use a different governor). However, I've been using CPU Tuner for quite some time before this issue started, and the issue persists after disabling it.
So I am guessing it's any of the following causes:
Static electricity
Keeping the phone in my pant pockets which may put some pressure on the screen
A problem with the battery or screen somehow (moisture?)
Some other hardware issue
Some software issue
Does anybody have any tips or other ideas about this? Thanks in advance.
Edit: I enabled some development options to show touch pointer location (white dot) and trails. Screenshot added. Phantom touches seem to be focused in the bottom center part of the phone, which is probably around where I grap it when I take it out of my pocket. Trails usually disappear the next time you touch the screen, but in this case the trails kept growing / adding. I made some real swipes (upper half of the screen) and they 'stuck' without the phone responding to them (the application did not scroll) due to the parallel phantom touches in the bottom. In this case the phantom touches blocked my real input, in other cases they cause some behaviour (scrolling etc.). However, sometimes when the screen is not responding, there are no phantom touches visible in this display mode.
Edit 2:The no-touch input problem seems to be 'triggered' most of the time I open the keyboard. Sometimes this is followed by the phantom touches, but usually they start occuring in the portrait mode lock screen.

clean you phone with an air duster than a alcohol swab make sure you dry it quickly and use 72% not 90%. make sure you get the corners... get a screen protector and apply that as well. then sbf to 217... and wipe data,,,, that should work.
if not it could be the ribbon cable,,, it may be frayed...

clean you phone with an air duster than a alcohol swab make sure you dry it quickly and use 72% not 90%. make sure you get the corners... get a screen protector and apply that as well. then sbf to 217... and wipe data,,,, that should work.
if not it could be the ribbon cable,,, it may be frayed...

Thank you, let me try that. Couldn't find the right alcohol pct. so I'd have to use some generic screen cleaning liquid, would that be okay as well?
My screen was having issues too. So I turned the dot thing on from the dev part as well. The dot seems to freeze as I'm opening my keyboard. And the dot stays frozen in place until I close the scree again. Any ideas on how to fix it? Also if the screen is open and I touch a spot nothing happens, but then when I close the screen it will sense correctly where I touched while it was open.
Sounds like the same problem, so I'm getting the feeling it might be due to the connectors rather than the screen digitizer itself. After cleaning it, I didn't have any issues for a while, but they started occurring again now.
The replacement part is not available right now, a bit expensive, and excludes the price for the required tools which I don't have yet. Warranty may be tricky as I didn't get my phone from Verizon directly. So if it turns out to be a connector issue I will say goodbye to the Droid family and just get another non-QWERTY phone.. at least until Motorola starts selling them (as 'Milestone' since 'Droid' is a Verizon brand) in Europe again. The Droid 4 is the best phone I ever had, this is potentially making it unusable for me though. Glad I didn't order a Lapdock yet!
Motorola will repair your phone for 168... out of warranty and all... I found this cheaper and easier then fixing it myself and guaranteed done right in 5-7 days..

Mine is still within the one year warranty. So I want to send it in. But I'm afraid they will check for the root stuff and they will consider voiding my warranty because I was rooted. I unrooted and did a factory reset to see if it would fix the issue. So this is my only chance left. I heard clearing the data wouldn't remove the qe process they use to know that I'm rooted. So I'm not sure if its worth the chance.
Flash SBF restores everything to my knowledge. No way to see what happened before the SBF flash.
I read in the original post for the DROID 4 ICS root tool that a sbf will not remove the part that says you were rooted at one point. I checked that first. An sbf flash is really easy. I was really hoping that it would work.
they dont take the time to check that stuff... if you sbf they wont know a thing...
bty found what u need on the cheap
Motorola DROID 4 XT894 Flex Cable Ribbon 27$
http://www.ebay.com/itm/Motorola-DROID-4-XT894-Flex-Cable-Ribbon-/150849219594
If they don't check it then why should I even bother? Does an sbf change something a factory reset doesn't? I've already reset it. I'll look into the fix though. It will depend on if I have the tools to do it or not.
SBF/fastboot will revert rom changes.
About that ribbon cable how would that work as the lcd is fused to the cable?

Cant be... it is glued in place and has connectors... how else could he sell you the cable by itself... http://www.ifixit.com/Teardown/Motorola-Droid-4-Teardown/7759/1
Just to weigh in on the whole root checking thing, SBFing or fastbooting back to stock DOES NOT remove evidence of root. qe still picks it up somehow in stock recovery.
That being said, they cannot void your hardware warranty for software modifications, it's the law (in the U.S.)
Of course, if you somehow softbrick your phone, they have no obligation to help you.
Edit: Just to clarify, I tried this myself just this morning. Full SBF back to stock + a factory reset, and qe shows 0/1, which indicates currently unrooted but previously rooted. No idea how their security works, but it does.

I agree it's probably not anything most people need to worry about... I still plan on sending my D4 in before the warranty is up, I've been having terrible wifi + 4G drops, even on stock (that's why I fastbooted in the first place)
I am a bit nervous though, because I've heard horror stories about Moto replacements. That being said, if Ops phone is under warranty, I'd send it in rather than trying to repair it. If it isn't under warranty, then I'd go for the flex cable, the Moto phones are built well and reasonably easy to work on.

I probably have some kind of warranty with the seller, not with Moto directly as I have no way of obtaining a QWERTY phone from them (they don't sell those in Europe for some reason). But I really can't miss my phone for an extended period of time, so I'd either need to switch to an old one while I'm waiting, or get a new one.
Since I don't have the tools available to open the phone properly and I don't want to spend any more money on this thing, I'll probably sit it out until it breaks. For now, switching the screen on and off one or two times seems to 'solve' it.

I still have tons of guitar picks so I just ordered a Torx set for this and future problems.. hope that pushing the connector around a bit can solve it already.

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!

I have same problem,this is shame of Samsung to not be interested for this problem, and this is my last samsung phone for ever!
(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!

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.
Cheers!

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.
