I recently bought a LG G5 used. Perfect condition upon arrival, except for the Google lock. I'm taking care of the lock. My issue is the screen. I had it on trying to figure out the lock when my battery died. At this point my screen was fully functional. I plugged it in while powered off and exactly 50% was black, the other exact 50% was a collection of randomly generated colored pixels, looked like white noise from an old tv. I unplugged it, plugged it back in and now I get black screen. In a dark setting when plugging in the device I can visibly see the screen energize to black for a second then turn off again. Phone still charges fine. The LED turns on, phone still powers on like normal but no screen. This sounds like a software issue, but I really don't know. Now I'm consulting you, the xda people for help.
I'm having issues with my G5 as well but it's unrelated to your issue however while looking for a fix for mine I did see a view things about the issue you are having. I believe it because the GPU of the device has failed and the only fix is a motherboard replacement, unfortunately.

Would you send me a link to the info you found? I can't find any evidence of a similar error anywhere on the internet.

Yeah I saw this video on youtube:
Its not a G5 but a different LG but the problem looks to be the same as you described.
The LG G5 "half screen static" issue is one i've personally experienced. From what I could debug, this is an overheating issue with the system board. For proof, put the phone in a freezer to let its core temp drop down. After a while take it out of the freezer and surprise! The screen now works fine, proving the overheating issue (until the system warms up and screen starts glitching again).
Some videos on the net have talked you can fix this by opening the phone and putting new thermal paste on the sys chips area. I've done it all and the issue still persists (others have reported success), so any other advice would be appreciated.
I ended up buying another G5 on the cheap and have the other for spare parts in case.
Here are two videos that talk about the specific issue you experience, the other talks more about the paste

I do have a motherboard on it's way, and anyone looking for a motherboard for your LG G5 BEWARE! Double check your g5 for it's model number (mine is located inside the device under the motherboard for whatever reason). There are 9 variants of the G5, mine is LG LS992. I will reassemble my g5 and try the freezer trick, update on that later.
Do let us know if the freezer trick makes the screen work again, it seems this overheating issue has appeared over several LG G5 variants (mine was H830).

The freezer trick did not work, put it in a 0⁰ freezer at work for 30 minutes and nothing. My notification led still works and so does the vibrator so it's still just the screen. And also I bought a motherboard for a VS987 while mine was LS992. They look exactly the same, and I studied each one. And no the vs motherboard didn't work. I'll have to send this one back and reorder the right one.
5 stars to LG for designing a really easy to repair phone, minus 1 star for intentional life stunting, minus 1 star for generating 9 versions of the g5, and minus a star for hiding your model no and imei IN the phone requiring disassembly and a screwdriver to read.

Hello!
I have a Nexus 5 with no warranty (according to LG, I need a receipt which I don't have) and the display is acting up. I noticed if I slightly bend the phone, the display flickers, sometimes fixes the problem, or it turns off. Over the last 6 months, the touch screen has been erratic and sometimes I have to hard reboot the phone to get it working again. Also on startup, sometimes I get the rainbow coloured "static noise" on the screen and then I push on the screen a bit and it is working again. Does anyone have any ideas what might be the cause and how to fix it? I feel like it's a ribbon cable problem but I have no clue. I went into Bootloader and factory reset it multiple times, pushed the factory image, pushed TWRP and Cataclysm.
Thanks for any and all help!

Replace the flex cable. It's fairly cheap.
If that doesn't solve your problem, then it's a screen or motherboard issue (i'd recommend paying LG for a repair rather than guessing between the two and possibly wasting money).

Thanks for the info. I have been looking for a while but I'm not sure which flex cable to replace? From the iFixIt teardown, it doesn't look like getting to the display cable is easy/possible. Do you have any links for what I should purchase? I'm comfortable with taking it apart and doing the work, just want to make sure I buy the right piece .
Thanks!

I've the same problem. atom bomb, did that work for you ? how did you end up fixing your phone ?
Hi everyone, I'm have an issue with my Nexus 5 and hoping someone here can tell me whats going on.
It started off with the sound always cutting out, and I have to press the back part near the "S" logo for it to return.
Eventually the screen would go black but I can clearly see a back light is on. Now not only does the sound cut out, and screen goes blank.
It has become very sluggish to reboot it. I hold the power button until the phone reboots "Google" logo appears and the android animation. Now during this time the phone will be so slow to the point of being crippled out and i have to reboot it again and again until it is normal speed returns. Often it will black out during this time.
I'm just trying to understand what is failing. I tried safe-mode and it still has the issue. I cleared cache, reset the phone everything, nothing appears to fix the issue at all.
edit: I forgot to add, when I'm on YT or listening to music or browsing the web, even though the screen is blank with just the back light on, the sound is still going (when it works). I get text/call notifications still during this time.
My Phone Details.
Nexus 5
Android version, 6.0.1 (MOB30Y)
no ROOT
No replies at all, I guess I may have to garbage the phone. Idk what else to do with this device to fix it.
Please don't throw it away.
You said that pushing at a specific spot fixes the problem (or improves the audio situation). This means that it's a hardware problem. I have disassembled it many times and I know the layout. Behind the 'S' of NEXUS is actually the motherboard cover, and under it are 2 connectors; one for the battery and one for an extra 'board' that is located right underneath the LG logo on your back cover. On that 'board' is your screen connector, and also the speaker rests on there, as well as the primary microphone, 3G and 4G antennas and of course the USB port. The connector for this extra board is actually located a bit to the left on the 'S' (when you look at your phone from the back, it's more below the camera).
Now I have to note this: While using my phone, I have experienced some UI hiccups. At random times (very rarely) everything would just freeze for a few minutes, though music would still play. The power button was useless apart from the hard reset, it was so badly stuck. This was a software problem, although it appeared MOST at one point when my motherboard was faulty. Since I got a new device, it happened again but only once. I'm not sure that this is what you are experiencing. If this is the case, then it's a software fault. Never happened on CM so you can give it a try.
But since it's probably a hardware problem, you can always check it out yourself. Obviously if you have warranty you are covered. Otherwise, you can try disassembling it, at least take the back cover and the motherboard cover off, it's ridiculously easy, there is a disassembly guide from ifixit (I think) online, just be careful not to break the clips of the back cover (xp talking). If you open it, keep away metal things and the first thing you do after you remove the motherboard cover is remove the battery (xp talking again). Obviously turn off the phone properly before you attempt anything. Everything is sensitive in there so be careful. What you should look for is the long connector that connects the extra board that is located at the bottom of the phone with the motherboard. That's what you are pushing so if it's not sitting correctly, then that's your problem.
Plus, everything in there, apart from the motherboard, is cheap and can be found on eBay so don't worry if something is broken (unless it's the motherboard, then no hope ).
I hope I helped.
Firstly thanks for the reply. I did manage to remove the back and get to the connector you were saying. I reseated this and noticed the phone was working much better. I noticed the following still.
When it starts acting slow/crippled pressing this connector fixes the issue. However once the screen goes black with just a backlight this method is rendered useless. Also sometimes when I plug in the wire to charge it will cripple and or go black. So I wondering if the board is shot as you suggested to order a new one, or is it the connector strip ?
Again thank you for the response.
It seems like this board is causing everything. First, check the connector on the motherboard. Make sure that nothing is wrong on the motherboard. Then you can remove the bottom black plastic thing that has the speaker on it and 2 antennas. Then, inspect this board. Check the connector of the display. There is only one big connector on it. This board is glued on the frame of the phone. You can remove it but do it carefully. Do it slowly so that you don't break it. First, remove the antennas extension cables from either this board or the motherboard, and then pull it out.
This board is definately responsible for the black screens and audio issues (unless your display is faulty, check its connector), but I'm not sure about the phone being sluggish. Since this board offers input to the motherboard, I suppose that it could be its fault.
Remove it and inspect everything. Then, if you want, you can order a new one. If you come across D820 and D821 models, I don't think that this part of the phone has anything to do with it so don't worry.
I will take a further look into this for sure, and report back. If you can provide which motherboard is required for my device, so I can also read into this and so that I may order it right-away. Is there any model number or something that indicates which board to order once it is open?
Thanks again!

You don't need to change the motherboard, not to mention it's very expensive and hard to find. What you need to replace is probably the flex cable that goes below the battery. For example this.
This is not model specific, you can use it with all available Nexus 5 models (D820/D821, 16/32GB) so it doesn't matter what device you have.
FYI, if you think that you should replace your motherboard (you probably shouldn't), you need to take into account the storage (16/32GB) and the network differences (D820 or D821, the only difference is about the 4G networking, the american version has some bands enabled and some others disabled, and vice versa)
Okay, I just ordered the replacement flex cable. It is going to take about a month before it arrives from HK , I hope it fixes the issues. I will respond to this post once it is here and installed. Thanks again.

in the meantime, pray it isn´t a motherboard issue, the conector can go bad and lose a few solder joints
I have exactly the same problem... I unmounted motherboard and clean everything but didn't help to much... did you find any solution ??
Siamer no solution just waiting for my delivery of the part. However it is getting worse with the blackscreens and crippled lag.

my is the same. sometimes is working for few hours without any problems and than starting again, on the biggining it was power button problem but not I don't even touch that button (I use vol button to turn on) and sometimes screen getting black (with backlight on) and can't do anything so have to reboot... it's so anoying! Hope that parts will fix it, please let me know if you will find some solution. Today I will open phone and clean all connections etc...
Thanks,

I believe the part may fix it. I noticed if i run my finger along the strip the phone may uncripple itself or just turn black all together. I'm hoping it fixes it. I will report asap but this HK shipping is so slow it will be a month. Also there is no tracking
ATM i'am just trying to becareful with it trying not to trigger the issue. I just did an OTA update using FlashFire (6.0.1 (MOB31E) i wish v.7 will be available for my Nexus 5 ha ha!
Also if the Nexus 7p arrives I may just buy it to replace this Nexus5.

Hi Omega59.
Today I bought air compressed can(name: air dust) and open my nexus 5 as much as I could. I clean everything, every connector, every cable etc. and last few hours is working fine... even power button is working ok. I will let you know in next few hours how it will be, hope will be still ok
Good luck!
siamer
[edit]
there is still same problem, working better than before, black screen not showing so often but still showing... I think tomorrow I will order oneplus3... Would be nice wait to see new nexus but how... :/
Yeah I'm not sure when the Nexus 7p will arrive, they not even advertised much. I will assume next year?
OnePlus 3 looks nice, but compared to Galaxy 7 it's a bit better slightly. You should check out comparison charts
Maybe they are making a OnePlus 4 soon.
oneplus 3 already ordered. I don't like samsung. I would say nexus "7p" or "pixel xl" will be launch october as always prabaly 4th of october - leaks saing that... next oneplus will be launch around july next year as I know. the only phone that I was thinking about was oneplus, htc10 or new nexus but can't wait to see nexus...
today by excident I broke screen in my nexus 5, got a little bit angry

siamer

You probably don't want to hear this, but if it's getting worse, it's probably because of the pressure you apply to it, you make it worse. Be careful when you apply pressure around the motherboard since it's very sensitive. You REALLY don't want to break the motherboard. So if you find yourself pushing on the motherboard too often, you might want to leave it and wait for the replacement part so you won't ruin it.
Waiting for your news...
My part arrived yesterday. I put it in was pretty easy, however the first attempt i had to redo the top connector bc it was still black screen and no audio. After I disconnected the top connector ran some alcohol over it, re-put the top part things are working okay.
Just a note, the little USB connector (charger slot) seems to be very tight compared to the old one. Maybe bc it's new and not as worn down. But even just to put the wire in, requires more of a push, same with removing it.
I will see how it goes before I can really say that was the issue. I will report after a few days about it.

I don't think N7P will be out this year, they have not advertised anything and we are almost in Oct. Right now they are all rumors.

When I changed my screen and housing it was difficult to slide the USB connector in too. Just make sure that everything is in place, there is a rubber think for the microphone, maybe that's what's in the way. Don't stress the connector too much.
This is what my son's One Plus 7pro screen looked like one morning. No physical damage just unreadable display. I hooked up a HDMI cable to a monitor and it displays fine so it's not software. Touches are responsive and I have called customer support with no solution. I did a factory reset and it still had the issue so definitely not software related. Didn't use the phone for about three days and now it's working fine. Am I going to have this issue again? Anyone heard of this problem with a purple and greenish display?
Probably something wrong with the LCD or LCD cable
Looks like screen burn-in to me.

In that case it's probably a faulty ribbon cable or something similar, can't see much more from what info we have
(Also, do ask if he had left the display on for a long time, maybe overnight, on high brightness. If so, it's a burnt screen.)

Heya, I have the exact same issue with my One Plus 7t Pro. The screen looks exactly like that and is perfectly responsive (except the fingerprint reader can't recognise my finger) but unusable due to the discolouration. Did you ever discover what the issue was? Did you send it off for repair?

One Plus customer service said they would repair but I couldn't get a ticket created because I bought it through Sprint. Weird loop of going back and forth through both companies. I did a factory reset and the issue didn't fix but twice it fixed itself. The first didn't last too long before the problem came back. The second time it just fixed itself and has been working fine since. My son was sleeping with it at not listening to music and I think it was a heat issue. After factory resetting it and turning it off, I let it sit there for about a day then when I powered it back on, everything was fine. Has been working great ever since. I make sure he doesn't have it on his bed at night anymore. My guess is it's heat or too much pressure on the screen. No way of figuring it out. Not sure if that info will help you or not. I would contact one plus support.

Heya,
Thanks for getting back to me quickly. I also purchased through a third party, so I have contacted them regarding repairs. Did your son mention anything regarding water damage or was this not a concern? I'm feeling a little more confident that it is repairable, cause it looks pretty scary!
I thought about water damage he did have it in the bathroom while taking a hot shower.
I have had this phone for one week and unfortunately have a problem with the small display on the cover. The display intermittently crashes and you are no longer able to see the time, charge status, signal strength, or any notifications without restarting the phone. Interestingly the crash does not affect the display of charging info when it is on the wireless charger. I am working with Samsung to get this resolved and they have assured me that they will replace the phone if necessary. So far they have tried wiping the cache, and having it re-imaged at one of their authorized repair sites with no success. Just wondering if anyone else has seen this issue or have an idea about what could be causing it. BTW...... I really love this phone otherwise.

I have observed the same issue. I've noticed that it recovers eventually but it is annoying as well. I called the premier service but they have not acknowledged it is a software bug yet. They had me factory reset but I am still observing the same.
I can also confirm it is not due to the case they ship with, nor the leather case, or finger grime that may be conflicting with the capacitive sensor. The rest of the phone knows the main screen is closed. My suspicion (speculation) is that it is the software as the cover display is really the only new hardware portion, in regards to most of the components from S10 parts bin, or Fold screen tech which has been pretty mature from a design standpoint.
Love the phone, hope they they can resolve this in an update sooner or later. Please let us know if its common to all.
Thanks.
I have the same issue. Been using the phone for about 12 days and the cover screen goes bonkers. It will appear some time but only clock and battery life, can't use it for notifications nor calls nor selfie camera. Plus open phone to answer is not functioning
This is my second Z-Flip - had the original one on release day and now the 5g version. Yesterday, out of nowhere (for the first time on either phone) the cover screen went blank. It works still (I can change songs and answer calls, for example) but the screen is black. This is 100% a software issue. Called Samsung 'premier' which puts you in the line for normal support, when they pick up they transfer you to premier (makes no sense). They suggest a factory reset. Odd thing is 2 calls today actually showed on the display. No rhyme or reason. I have tried powering down, restart, and safe mode. Very frustrating.
I'm also having this issue, I had a different issue in the past where the phone would not recognise when it was opened or closed and just behaved like a regular smartphone with screen on off. The cover screen also came on at the same time as the main screen so basically the phone thought both were one display.
This time I am getting the issue as above, the screen is black, pressing power does not bring it up (always, sometimes it will randomly show and I can use it, before a factory reset I just did it wouldn't be functional as touch only worked halfway, I could drag it left or right but it would just stay where it was, thinking my finger was still on it.) if I press the power repeatedly sometimes it shows, sometimes it shows offset so only half the display lights up and has moved everything to that side and cropped it. It's completely a software bug, my phone has no scratches or dents and is in great condition. It's a newish model as my original Z Flip got replaced by my network by a 5G model.
Hi All
Has anyone had any issues with a black screen?
Everything else works like incoming calls and notifications but the screen it totally black!
Woke up early hours last night and noticed no AOD so tried to turn my phone on but the screen was just dead. Tried the volume and power button but still no joy
Power it down completely then plug in the charger.
If nothing shows on the screen it sounds like you lost some significant hardware... maybe just a connector.

Same happened to my SM-N9860 unit when I woke up today. I about to unlock and the display suddenly went black screen. Did everything but no luck. I am also sure it's the display that's f***d up. The phone is still working - I can still access it in Dex and Link to Windows. This is my second Samsung phone with f**d up display for unknown reason. This is crap Samsung. Not expecting for this from an expensive flagship smartphone. I swear this is the last.

Poor parts QC.
Samsung will substitute components and smaller chipsets in the middle of a production run. This can lead to unpredictable behavior especially after firmware updates... or outright failures like this.
Not reassuring especially with a flagship phone.

Agree. But I am happy that it's working fine now and I hope it will not recur.

hi im facing exact same thing in my N986 B Galaxy Note 20 Ultra. I had 10 percent battery left. i had put phone on charge and saw after 20 minutes and tghe screen was black.
Now its blackscreen can connect with tv via hdmi dex mode
but phone restarts after 10 minutes.
the touch seems fine as mouse function works phone is on but no display
can you tell exactly what you did when your phone revieved after one day
did u keep it on. charge all tiime tried reset or removed charging
or nothing and tried after 1 day
Edit After 24 hours of tapping slappingrebooting installing stock firmware. my display came back alive.
last thing was i was using phone in dex mode and trying to open close camera app rapidly by direct touch on screen. i dont know what worked but it saved my 300 dollars of screen replacement
I have exactly the same issue.
I was typing on whatsapp when suddenly screen get black. It was on friday morning. Notifications were ok, voice commands too. Touchscreen ok, I could use it normally when using my TV as screen with HDMI cable or with my notebook, when connected to windows or even Dex.
One day earlier I had an issue with the new magisk update. I freeze magisk manager wich was force closing but later, I managed to reinstall with dex and was working fine. Not sure if it's related.
I already flashed fresh stock Android R rom, wich I thought would solve any issues related to magisk or any other software issue.
24h after flash stock rom and keep force rebooting and taping, and my display is still dead.
Tried to tap, slap, shake (I can her some noise next to camera module when shaking, is it normal? I took off S-pen and microsd tray to see if it was the cause, but the noise still persists). No damage, water, or anything else. Only 2 months of use.
Display is still dead.
I'm draining battery now with some apps that also vibrate phone, to see what happens when full drained.
I live in Manaus/Brazil and repair centers are not working until March 23 because of Sars-CoV2. And my knox is tripped. It would cost a lot If I have to replace display or even the phone, since they probably will say it's no longer covered by warranty.
Any tips are welcome.
Thanks in advance.
Hope I have that lucky as well.
It happened to me again today. Surprisingly, a strong knock at center of the screen revived it again.

Hardware failure. May be a loose connection, cracked solder joint, trace failure on the mobo, or a bad component.

Yes, obviously. Samsung already replacing displays of those who are having this issue.

Not good if there's a recall... crap QC is getting to be a bad Samsung habit.
Those of you with BSOD issues: Did you have intermittent wifi connectivity issues as well? My N20U had the 'connected to wifi AP but no internet' for the last month. Then today after unplugging the OEM charger, checking charge level, never picking the phone up from the desk, and returning to it 30 minutes later the BSOD had hit. No amount of hard restarts or waiting fixed it and it had to get shipped back. Just wondering if there is any correlation between the wifi issue and the screen going out, and if people should start sending their note in ASAP if the wifi problem occurs before the screen goes?
hello
i had the same problem (didn't have any Wifi issues before)
and after the screen went black for 2 day , it came back and worked for a few hours.. then went off again and Never came back
i tried everything, resets , cables , connecting to Dex or Hdmi , updating.. but Never worked
i went to Samsung and they said screen must be replaced ( will pay for it as i am out of warranty)
can you tell me what have you done or if anything worked for you?
My screen went black after a screen replacement. Only the front glass was broken not the digitizer or actual screen. From what I can tell it's not just the screen that's dead, it's the digitizer too. The S-Pen board underneath it all isn't even registering. When I plug it in the computer doesn't see it so Dex won't connect and there is no signal for HDMI to work. Had the USB port replaced just to be sure it wasn't a bad port.
It's like some one took the graphics card out of a computer and took the touch screen monitor. The phone still gets signal. It connected to my smart Fossil watch and I could answer calls and texts.
But the phone is 9 months old. And from what I've heard from parts distributors it's not the screen that's the issue. So now I have a new motherboard. Now I have to figure out how to program it....
