SCREEN REPLACEMENT PROBLEM - Huawei Nova 2i (Mate 10 Lite / Honor 9i) Questions

hi there, I just replaced my screen for the umpteenth time but, on this occasion, it hasn't "taken". The old screen is totally obliterated, smashed display, but it still takes power and behaves as it should (lights up on disconnection of usb charger, for example). The new screen? Not so much. It does actually work, it shows the picture fine, but it only shows it for a fraction of a second then blinks off. When I press the power button again it does nothing, as it thinks I'm turning the phone off, then when I press it again the screen comes back on for a half a second or so and same issue. Have checked all connections, all fine, have swapped in the old screen to confirm it behaves as it should, all fine.
I'm wondering, could this be some kind of gpu/driver issue? Or has anyone experienced this before with a replacement screen and it's just a "dud"? Absolute downer as I've been waiting for it for a month or so and literally can't afford to buy another one at the moment, really bad year

I had a similar problem due to display incompatibility.
I have the phone marked FHD-D on the cable and the new display was FHD-A.
Or, the new display is not original...

Thanks for your reply and yeah, I'm figuring this is what is happening. However, the cable/screen are all one piece and were bought together, so is it possible they'd mismatch the cable to the screen themselves? idk, anyway, I've opened a dispute and have now been told that I'm stupid and that I have installed the screen incorrectly and not connected the battery (absolute gibberish).
I made a couple of videos for them, idk, have a look and see what you reckon but, indeed, to me this looks like straight up incompatibility as the screen isn't being driven properly by the phone (and, as you can see, the old busted screen behaves correctly)
Video of old/broken screen showing correct power response and on/off behaviour:
https://streamable.com/n16xo8
Here is the video of"new" screen which is clearly not correctly supported
https://streamable.com/28w8m2
Well hopefully I can get a refund for the part and get another. Can't even afford to order another at the moment until I get the refund :/ Lost my business last year due to covid and don't have access to state benefits or the like, so have just been trying to keep the head above water for the last year and a bit, so believe it or not something like this is a big expenditure for me these days :/

The original screen is "Boe" (see screenshot), this can be verified via the "Device Info HW" application.
Too bad the phone won't start and it can't be verified...

Yeah, it's a pain, I guess the display is just not going to work and I'll have to somehow get another - hopefully I can get the refund okay as those videos show it clearly doesn't work! The phone does actually start up, everything is going on fine aside from the screen. As I have to press on/off several times to get the screen to flicker, I don't have time to put in the unlock code and get into any menus, and then when it goes off I'm back to jockeying the button until it lights up again, at which point of course it's returning from a standby state so it's going back to the code input. BAH!

hello how are you 1 month ago I bought the second-hand mate 10 lite with the crashed but functional screen and I decided to buy a screen since the one I brought stopped working the touch screen everything was fine in the installation but the same thing happened to me as you understand normal but the screen does not work when the device is finished charging and putting the pattern turns on the screen and also that when I make a gesture it does not work I have to press a little hard and I realized that the screen came out a slight defect and I cannot request a refund since remove the security seals when installing it in your case if it came out with a major manufacturing defect
Note 2020 just look at the date of your post and still comment hehe greetings from Mexico

defective screen?

my imagio screen is tweaked I can see a little fluid in the screen and it will not respond to any touch. Did hard reset twice but no change. I have to bring it in tomorrow to a store, cust service was no help said they may charge me. At 37 days now this blows.
should I remove cabs before I go to store for warranty? even though the defect is a physical issue?
A hard reset should put the phone back to the factory software state unless you mean a storage card, but then you should take that out before replacing it since that's your own. =)
they are replacing it, I didn't undo my changes before I went in to the store. The guy there said I didn't have to. I have to wait to have it shipped from warehouse-no store stock within 100 miles. Maybe by Monday? I can only accept phone calls with it.
I had the same thing happen to me yesterday. I noticed my screen wasn't responding very well in the center, then I looked closer and this is what I saw

Sending it back to Verizon when my replacement arrives on Monday. Completely a hardward problem
yep that's it
Did you notice your screen not responding as well?
Just noticed I have it as well.. No issues with the screen response though.. I wounder if I should take it in anyway just to be sure something doesnt happen
leads right into not responding at all. I guess the fluid between the layers bleeding out. I think the capacitive screen responds to the stylus when the layers make contact?
started having issues with tje touchscreen.. took it to the store and the first words out of the reps mouth wad "what did you do to it ?"
lol...
then he says that it is normal to have the colored swirls like in the picture posted and that it wad from the oil on my fingers.. lol again.. at that point I say that none of the display devices have this and I showed him how the scrolling jumps around on the applications list..
he ordered me a new one and it will ne here in two days...
anyone else having this issue?
Had the same thing happen to me, they had to send me another phone the other day.
jeez.. the typing really shows how bad the screen has gotten..
Wow, I just had the same problem. They swapped it out for me and told me this "wasn't" a known issue with this phone.
same thing happened to me...
I was outside in the freezing cold last weeek and tried to use my phone. The screen was literally frozen... the phone was not locked up, but the screen would not respond. (The buttons would work, but unfortunately I was trying to call someone other than the last person I called so I was out of luck. Found this thread and realized mine had the same problem. Took it into the store and got a new one in the mail yesterday..
This might be a coincidence but I first noticed this right after I installed a screen protector - one of the vinyl ones that you wet with the supplied liquid before putting on...
me too
I had to return it too... I could see fine hair lines showing up more and more everyday... got a new one... next day some lines started to appear... It is winter and I think exposure to freezing temps is bad... I was warming up the car and put the phone on the passanger seat, I forgot something and went back inside the house for 5 mins.... the inside of the car was freezing the I grabed the phone and it felt VERY cold too... I was like "damn!" that's when the new line showed up on the second NEW phone....
Looks like Newtons' Rings to me
Hi guys, we've had similar complaints in the Blackstone forums. I think the general concensus there is that these "Newtons Rings" are due to delamination of the screen and digitizer. Looks like i'll have to add this to the Imagio Wiki as well.
On the blackstone there's mixed signals as to wether or not it's a "known issue" from HTC as only certain regional HTC repairers will replace it under warranty.
Both the image, and the descriptions you guys are giving says to me it's Newton's Rings. If you're getting them replaced under warranty then you're lucky
this same thing just happened to me 20 minutes ago! I am going to the verizon store after work I am glad i have a years insurance on it!!!
Just like everyone else, I had the same thing happen. VZ got me a new one in 3 days... Must be a manufacturing defect.
they sent me an ozone as a replacement and i called them up and she said they were all out of imagios and tp2 and that the ozone was a fair replacement and i told her i already had one and its not even close to the cost that i paid for the imagio anyway i got no where with the customer service and i went to the corp store in town and got it settled but it wont be here till friday which sucks!!! this will be number 3!
Maybe someone can find a site that sells screen and digitizer replacements.....

Z2 touchscreen defect

Hello,
I've just created this new thread to inform you about how my Z2 is broken after two weeks of use.
Today at noon the touchscreen started to do some unusual things, I wrote some messages and I recognized that I wrote multiple letters when touching just one, not one aside the tapped letter but at the other end of the screen.
I wondered how that happened, tried again and again, restarted the phone, nothing changed.
At home I called sony care to ask if anything like this was already known, they just advised me to "repair" the phone through pc companion.
Now I can say that nothing worked and I'm sure it's a hardware defect, by experience I would say it looks like water damage to the digitizer/touchscreen controller.
The flaps were always closed except for charging at the bedside table and I'm sure it didn't rain there.
I will keep you posted what is going to happen involving warranty and xperia care.
Greetings

now I was able to use the manage attachments button, must have been an internal error, thought it was spam protection, too...

I had the same problem, after two weeks too. I got a new one, but now I'm scared...
This also happened to me when I'm texting, it inputs multiple letters. I think this is a software issue as it happens after making a phone call. I changed to TouchPal keyboard and it happened less. I think the Xperia keyboard has bugs as well. But it rarely rarely happens and I can't duplicate the bug.
Don't know what causes it, seems software related to me. Turn of the screen and turn it back on worked for me. Happened just once...
Lucky for you, problem persists at the exact same spots.
Since yesterday the touchscreen went full rogue a few times, "touching itself" everywhere for a few seconds.
Trying to change it at the shop of my provider today by implied warranty.
Check your screen with this app:
https://play.google.com/store/apps/details?id=com.easylabs.multitouch&hl=pl
Got the phone to my provider this afternoon, the shop assistant examined the device extensively and was pleased by getting informed about the older batch numbers that have some issues (mine was a 14w17 with off center camera and flash).
He started to write down contact details and a description of the failure.
Then he got to a support guide for checking the device before accepting it for warranty, in this guide there was a step to check the wetness indicator beneath the sim card slot...
Suddenly "ohhh...", he said the indicator turned red, i looked at the spot that looked to me like the indicator and said, ok, yes, seems like you are right, ****...
He said that he is very sorry but he can not accept the device like this.
I went out, knowing that he is not to blame for this, called xperia care and was really upset, asked for the nearest xperia care partner to do a water-proof test.
The woman at the hotline asked why I would want to do the test, I answered because the touchscreen is defect and the guy at the provider store said the wetness indicator went off.
She answered that the Z2 has no such thing as a wetness indicator, at least not one that is visible from the outside, the thing you can see is the hardware reset button and the pcb.
Went into the store again, went through all the steps and got a 1:1 change of the device, the shop assistant was amazed that I get a 1:1 change, that would nearly never happen.
We agreed that it may be that Sony informed vendors of faulty batches so that they get replaced without hardware checks and his support guide was an old version of the Z or Z1 because the device is still too new.
I'm happy that I get a new device without any more hassle.

So how is the screen of the new unit?

They would have changed it directly if they had a device in stock, they ordered a new device directly so that I hopefully get the new device on friday.

I have exactly the same problem with my Z1 since i upgraded to 4.4 and whats bad is that its even present in 4.3 when i downgraded. Before upgraded to 4.4 i never had such an issue, its very annoying!

Sorry for replying this late...
Got a device out of an older batch, it's a 14w15, everything is good except camera displacement.
I think the vibration in this device feels a little weirder not as good as in the last device.
I even got an unbranded decive, no magenta t at the startup and less apps to deactivate.
Keeping it and hoping that it lasts the next two years.
Thanks for your replies and support.

Yotaphone 2 e ink blank row problem

Some days ago my Yota started to restart on its own. It happens once a day usually.
The biggest problem i noticed is that on the e ink screen now a white row is present and does not refresh anytime.
Firmware is 1.87a eu, original, not rooted. Anyone has experienced it? I hope there is a fix cause I do not have time to go to a support center and leave phone there to get fixed.
Cheers

I bought my Yota about 2 weeks ago and firstly epd was completely fine then I noticed horizontal blank stripe few pixels wide that does not refresh. Then another one appeared, this time vertical and only 1px wide. Today I got third (next to the 2nd, also vertical).
I don't know the origin of those, as had 2 ebook readers before and never experienced such a thing. Wonder if it's a software issue or some failure with the device. Tried to Google it but it looks like it's not a common problem. Thinking of flashing the 1.99 rom - maybe it will help.

I am sure that this is a hardware problem. I have my third Yotaphone now (because I love the concept). One I got replaced because of the EPD showed some lines. Another one has a fine vertical line, another one a fine horizontal. They are on different software releases. one on Middle East, one on European SW. No difference. The places are very different. So, a hardware issue.

Hi! Yesterday I have got the same thing - dead horizontal stripe appeared on the e-ink screen. Please, give an answer, based on your experience - what will happen with the screen soon? Can the screen work for a long time in this condition, or is this a sigh of a soon total failure? Thanx 4 answer.

Based on my experience it should go on working as usual, but the stripe won't disappear. Speaking about it with a friend of mine, he told me that this is a common problem with all e-ink displays. So if it is still on warranty my suggestion is to send it to be fixed. If it is not, do not panic, should be fine, at least I hope. Mine goes on without any problem , exception made for the stripe.

Won't be fine, sorry to say that. There will be more and more lines until the screen will start to behave weird in total (inversion of colors, no refresh, not working yota mirror..). I'm 99% sure that's overheating problem and plan to open my Y2 to find out soon.
Had 3 other devices with eink screen before (2 nooks, 1 Motorola phone) and haven't seen this issue yet.
Better use your warranty before it is too late.
I purchased my Yotaphone 2 in June 2015, in August 2016 a horizontal line appeared about 1cm down from the top of the screen, then about a week ago a short vertical line appeared, just off centre going from the top of the screen down about 2cm. I asked yotaphone and they said to take it to their service centre but this isn't very convenient for me. I am hopeful it won't get worse! Interesting to see other's experiences, it is clearly a common problem!
<<edit>> The two dead lines are 1 pixel wide, the horizontal one is light grey in colour, the vertical one is white.
Three days passed, second line is dead.
It's about 1 mm from first one.
No warranty, unfortunately... Screen replacement costs abous 120 USD. I'm sad
Ok, so I opened my Yotaphone to find out what's causing the dead rows:

Thanks for photos! My horisontal rows are at the same place as yours. Furthermore, this situation is very and very common, many people have rows at the same positions.
If it is not hard to remove the screen, we can replace them ourselves: my idea is to order new screen from China, it costs about 60 USD there (at AliExpress).
The bad thing is that the new screen can be also defective.
Please explain how you removed the grille at the bottom of the device.
it's simply glued, all you need is to get some pincers and pull carefully. You can follow this guide:

To your mind, is it possible to change only the display without replacing the glass? Now it is very easy to buy used phone with a broken rear glass, but the working e-inc display.
the epd screen is embedded in the plastic case below the glass, if I wanted to disassemble it I'd have to rip the poor thing apart
Hello everyone,
Just to let you know that a recent french buyer (that's me) of an YD201 discovered after 3 days of use 3 lines out of order... the very same place...
I'm dealing with the seller efoxtienda.com to get a solution. I paid with Paypal in order to benefit from protection...
For now on, the lines are 1 pixel wide... so that's not a real matter... but I don't want to wait till it gets worse.
I will share the issue of the negociations.
Enjoy.
I ordered one from GearBest (Y201) and I really hope that it is without hardware issues.

Dont forget to make a video of unpacking...
Because of the EPD, my phone is getting worse:
-it very rarely refreshes itself, and if it does then looks like above..
-the battery drain is terrible (50% loss in about 2 hours, mostly screen off)
-the heat of the previously mentioned capacitors gets scary
-phone reboots itself once a while
I've decided to disconnect the EPD (almost) completely and see what happens:
Digitizer (1) and EPD (2) are disconnected now, but there's some link at (3) and can't be unplugged. Not sure what it does.
Beside physical changes, I used Titanium Backup to freeze all EPD apps I've found (altogether was 39 apps) - especially Organizer and Counters were stopping themselves just after the reboot, very annoying. Will give you info about how it works in several days, as for now the only difference is around 2sec delay* between pressing the power button and turning on/off the screen.
PS. The good news is that, now I don't care about destroying the EPD, so perhaps after new year will have some fun with capacitor replacement
(*)EDIT: It's good now, just don't freeze Back Screen Manager app
I do not understand about (3)...
How can I change the screen if (3) can not be unplugged?
PS How much time has passed since the first row appeared?

Sorry, my bad - I took another look at the Y2 disassembly video - (3) can be disconnected, although it looks like soldered to the mainboard. Didn't try.
I bought my phone in the middle of September, first line appeared few days after.

Open a ticket with Samsung and send it in for a screen replacement. if there is no water damage or physical damage they will fix it for free under warranty.
I have this green issue with flickering lines...
Warranty expired...
****sung
Are any of ypu rooted s8 u model. This is a byproduct of the combination bootloader used for rooting
Green Screen of Death
Very sorry to hear about it
While my S8 was messed up, my sisters s7 Edge had the exact same problem...
https://forum.xda-developers.com/showpost.php?p=77189854&postcount=16
Now slowly, the green screen would start to flicker at times and lo one day, it would turn into a pale green light. You wont be able to do anything with the phone.
My IMMEDIATE ADVICE ...
TAKE a COMPLETE BACKUP of your data as soon as you read this message.
Secondly
Try turning the Blue Light filter off, Change the saturation of the phone and see if you are still seeing the green shade,
Send this device to service center.
EDIT :- Just now noticed the OP's date is almost a year old.
I got a same issue too today ****sung!
Is there a fix ? i dont wanna pay 250$ to replace the screen.it works well in full brightness
i got the same green screen on galaxy s8+ today after using it for 2 years i had custom kernel with hari rom, the phone is usable in full brightness, it has green overlay with horizontal line flickering over it i think this a motherboard issue, have your issue resolved ? what you did? i am thinking to change board and see
I have fixed my phone twice with this problem. You need to heat up the screen. Full brightness then record video for an hour. You should see the greenness recede. If there are green lines st the bottom which don't disappear, use a hairdryer on the screen. You will see the green vanish in 30seconds. When the phone cools, it will come back. You need to keep regularly reheating your screen to get rid of it, like every 20 minutes for a day or, 2. Eventually it will clear up. It's a pixel what issue. Heating the screen repeatedly restores functionality, after least in my case.

It is correct that it works in full brightness. Turn off the adaptive brightness and voila you can continue to work with full brightness. However, you can also reduce your
pixel to full HD from QHD to continue in this mode. I have been working on this for last few days else the ****sung care only want's to replace the screen combo .
Will try the heating methodology. I have doubts about battery also and planning to change and see.
Same issue just popped up today for me. Rooted nougat ROM with safestrap. It's definitely not the screen itself, and it's behavior is Sunday strange, it'll show up on webpages or other screens that are mostly white, but not on the dark mode applications.
so it's green on this thread and it gets less green when I open Chrome's settings on the top right.
Reboot fixes it. Until it comes back again.
Started to face this green tint issue on my S8 recently, the phone worked well for the past two years until suddenly one day this green **** happened. Never dropped the phone and never rooted it. For now rebooting the phone solves the issue, until it comes back. Till now it happened 5-6 times in a week. Rebooting fixes it and then it runs normally for sometime (or somedays) then it happens again.
Any solution?
Apparently it is a software problem, something about some screens batch that does not received well those new patches. i took my s8 g950fd at a Samsung authorized store and is was what they told me, but they don't fix it for free if it is not on warranty even though it is a Samsung software problem. I have tried to root and change roms, but it seems my cellphone does not accept root or new roms. if some one know how to help me id be grateful.
my screen has green after unlock bootloader. i didnĀ“t anything, so im tired :/
Sounds like a firmware bug* on at least some of these. Samsung tech support sucks elephant balls bad. Obviously Samsung is well aware of this issue by now.
*during a production run Samsung will substitute smaller chipsets and components as needed. This can cause erratic firmware/update behavior as the substituted components don't have the correct values and/or code. If so you're in a fubar because Samsung is unlikely to supply the needed patch at this late date.
You can try flashing the original firmware, be wary of updates. It could be a system apk update as well.
It could also be a hardware failure on a whole batch(es) of these phones.
started having this problem suddenly now, didn't drop it, didn't do any updates. wow!

Home button and screen problem

Today i encountered a big problem with my Mi A1. After i unlocked the phone in the morning, the home button (the back and recent buttons work) and right side of the screen stopped working completely. I tried to restart the phone many times and look up the issue on google but nothing worked.
Than i tried turning on the "Pointer location" option in dev options, and it showed me, that a perfect portion of right side of the screen doesn't work, when i was sliding my finger around the right side, obviously not in such a perfect line (as seen on the screenshot).
I would like to know, if it's related to me updating to a new security patch the day before, some hardware issue or something else.
I would apreciate any help.

Thank you for your response
I didn't really change anything on the phone, when the problem appeared. Once i just unlocked it and the screen side with the home button stopped working.
I'm running completely stock android 8.1.0 with an October 5th security patch. I have updated on that security patch the night before, but i don't really think that this could be the problem... or could it be? I have a crack in my screen too, but it wasn't problem for a long time, since i dropped it months ago and i was living with it completely fine with no problems at all. The only thing i have changed on the phone is just a launcher - Nova.
And even more weird is that it sometimes works. For example last night it started working again, everything was fine and than in the middle of today it stopped working, again. I just locked the phone with the problem gone, unlocked it 5 minutes later and boom... it was back there. I don't understand this at all. Could this be due to some bad hardware connection, like wrongly connected cable etc.?

Well i think it's the crack on your screen that mess the touchscreen.
If a factory reset doesn't solve it then it's hardware?
You can have a fully cracked screen and phone will still be usable. And you can have a single crack but badly placed and screen is f***ed up
Try to repair it by yourself or by a professional.
Broken Screen rarely pass with the warranty...
I'm sorry bro.
Still try to factory reset the phone, just in case

Okay, I'll try to reset the phone, but i don't really think it could be the crack, because it happend months ago and worked fine.
Is there any other way, than a factory reset and hardware repair maybe? Because i don't really wanna pay 1/3 of the phone price just for a new screen that doesn't really affect anything. It's just a little crack on the top half of the phone, that doesn't affect the digitizer. (Or it didn't affect it for months)
Alltho thanks for your help. I'll try the factory reset and if it will work, i'll add a new comment.
