[Q] Screen goes partially blank

Hey, so I have this weird problem with my G Flex 2.
I got it around 40 days ago from U.S. Cellular.
I have run into this problem about three times now, and from what I can remember it always happens when I have music playing. I tap the screen on to the lock screen then let it go to sleep or turn it off myself. When I wake it back up the screen is all black except for a few millimeters on the top, where I can see some display.(*note, this doesn't happen every time)
I am able to scroll through the display but no pop up menus. Since the battery is sealed off in the back of the phone I can't use that fix, holding the power button only brings up the menu option to turn off the screen which doesn't do me much good since I can't use the screen.
If I wait for 5 minutes or so the phone will right itself, but I don't want this to be a persisting problem. I'm not sure if this problem is tied to the music playing, it hasn't happened when it isn't playing, but I play music on my phone quite often. (note* I am playing the music from my phone, not streaming)
If you need more info I'll do my best to provide it. This is all I can think of right now.
Honestly, I don't expect anyone to have a fix yet since the phone is fairly recent and not as popular. I tried looking under G3 forums since the UI is pretty much identical, but I didn't find anything.
Sorry, my post is a little wordy.
I'd appreciate any help anyone can provide. Thanks

Yes, this has happened to me twice recently too. Once the screen was completely black except for a bright white line at the very bottom, but the phone was still responsive behind the dead screen. The other time there was a distorted/ghosty notification bar showing at the top but nothing else (like what you reported). Then the problem would resolve completely and spontaneously after resuming from sleep a few times. I have the Korean model (F510S) which was a gift so I'm stuck with it - no returns or warranty available.
bonebeatz1234 also posted about a similar problem. Seems like a hardware fault?

The replacement phone screen was fine i had a different issue of over heating and had to return it . I opted to get another device the note 4. Didn't wanna go that route bit had no choice i loved the design and ui of the flex 2. I wished lg would of just ditched the 810

Hi, I encountered same problem here.
Is anyone able to send me a screen shot or a video of this problem.
As I need to use this to prove the situation and claim warranty from the seller, however I didn't take a photo or something when the problem happened to me.
please sent to [email protected] if you have the photo or video and many thanks~

Just had this problem also had a g flex 2 for about 21 days now and it happened to me after a restart in the car with a pinkish line at the top and the phone was completely responsive even though the screen was blank
I think it might have to do with heat cause I held it by the ac vent while I was reading this board on my nexus and when I looked back at the phone it was working perfectly
But I swear during my time with the phone it heated up way more than this time and this time the phone wasn't even hot
I reset the phone like 3 times before I held it to the vent and it didn't help at all
Using the att variant with android 5.1.1

Have the same problem every now and then, found a recommendation on another website and in the instruction manual to reset the phone by holding down the power button and volume down button for about 10 seconds or to turn it off by holding down the same buttons for 20 seconds. I find what works better though is to just leave the phone alone and it corrects itself within about 5 minutes.

Having this same problem. Happens once every couple of weeks. Any updates on this?

I think that this is a heat problem....everytime i left my phone in the sun, it show me this strange error.

I'm not convinced its a heat issue. I looked at my battery chart the last time it happened and it was barely over 90 deg. It seems it happens to me when it is charging PLUS doing something like streaming music or GPS is on. I need to start taking notes. I should have done that before.

this have happened to twice too. weird anomaly.

Having the same random issue. Today it happened and reboot would not fix (it usually does) finally after about 30 minutes the screen came back to normal. I now disabled lock screen in case I need to get data off the phone from pc ? in the case that the issue becomes permanent.

although it's an old post, but worth to mention, that It can happen to all the LG Flex 2 models.
It is caused by a heat or inaccurate voltage. let me explain how it can happen:
heat - when you put the phone on the car's cradle under the car's front windows during a sunny day - it will happen.
voltage/heat - when you charge your phone and not using your original charger (eg chinese car chargers) - it will happen.
so what to do? I've noticed that putting the device over the cat's air conditioning , can reduce this to few minutes. also, if you can, mount your cradle over one of the air condition outlets and it will freeze your phone all the time

What benefits have you noticed from 9.5.7 OTA and what's still broken?

This is for a better understanding of where we are standing now. 9.5.7 was rather a significant hotfix, but did they deliver?
What benefits have you noticed from 9.5.7 OTA and what you think needs work still.
I already noticed pictures are more accurate on low light whlie also more popping and saturated in normal mode,
Also after receiving a phone call, the loudness and clarity could be told from 5 feet away without using loud speaker.
I wasn't really experiencing most of the other issues, so, what was fixed for you?

Ghost touches are fixed! As far as the camera goes... i haven't compared it yet, but people say its much much better. Ambient display was a bit buggy for me on 9.5.5. Sometimes it works, and other times it didn't, but after the update i am yet to see it not working. I really appreciate this update and hope for more improvements in the future.
Edit: Btw first time using a OnePlus device and im loving it so far. Only issue for me is lack of sd card slot when it has 2 sim slots.

Ambient display is fixed and camera has improved hugely, especially night mode... Huge improvement

Much better overall...

They claim to have improved touch response. Maybe better now with tempered glass protector.

Still difficult to pull down status bar while in a call.

Full screen games still got issues with getting statusbar visible.

A little more overnight drain... 5%... might take a few days to settle in again or something... don't know

I didn't know about that issue, it would be good for you to submit it it in OP forums. Meanwhile, Only if if you have rooted you can fix that by installing Renovate ICE magisk module and enable Statusbar peek in Rice Tweaks

Yeah I posted it on the OP forums the first week the phone started shipping out and I am using the RICE. Thankfully they offer a work around.

Ambient display still broken for Nova Launcher and I'm sure for others as well, when unlocking it goes to black screen and only nav bar. Which as been reported by others. When ambient display disabled everything works fine.

Takes about 5 seconds to take a nightscape picture, I can´t hold my hands steady for that long, so using regular mode for night photos which actually works surprisingly well. Still would like to have the option though.

*808*# to calibrate promixity sensor doesn't work. Unable to open the sensor calibration. And the old pocket mode isn't in settings anymore.
Conclusion is that while being carried in my pocket screen goes on very often.
Anyone else?

Warp charged is borked for me since 9.5.7, it changes between warp, normal and no charging about every 5 seconds, my old 5 cable does the same but funnily enough warp charge pops up with it, and my 5 dash charger works fine. And once the phone is about 90% the issue goes away completely. Also a factory reset didn't fix it and I know for sure I didn't have it on 9.5.5 because my phone vibrates every time it switches back to warp charge (which happens a lot and repeatedly as well as the animation on the lock screen) and its never done that before. (here is my post on the OP forums for any that want more info: https://forums.oneplus.com/threads/op-7-pro-warp-charging-not-working-anymore.1051041/)

I didn't see the ghost touch issue on 9.5.5, but right after booting into 9.5.7 I saw ghost touches
I have disabled NFC now and have not seen it since

Try charging while the phone is off, let the battery drain low, plug it for 1.5 hour. If it goes up to 100% in that time, then its not a hardware malfunction but an OS bug

did you debloat you OS? I did using tomato debloater, and with it some some of the calibration/ engineering mode went away as they where part of the apps to be removed. if reflashing your OS wont solve it for you, you might have a broken sensor

No, that's not what I wrote. Engineering mode app opens, but the calibration section doesn't work. It was working before. Someone else confirmed it to me in another thread.

I'll give that a try tonight and see what happens

I do not take many pictures I am glad to read though the camera may have improvements.
Noticed no changes so far.

Green and purplish screen?

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.

Black Screen Of Death

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.

By the way, how did you fix your phone?
I tried searching it on the net, seems a number of Note 20 ultra units are experiencing the same.

Seems that display replacement is the only fix.

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.

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.

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....

Were tou opening and closing the camera while mirroring screen? or on blind?
It seems in your case, the display went back to normal as strange as it turned off.
Could you please share the mentioned youtube video?
Hope I have that lucky as well.

Sorry for the late reply mate. The Scenario when display got back alive was.
1. My phone was connected via HDMI to TV in Mirror mode (Not Dex Mode). I also had mouse and a keypad connected since i am using Samsung Dex pad which came with my old note 9
I have from day 1have doubts about the stock camera app on my Note 20 Ultra. The app misbehaved from ranging to camera fail, and force closes on Android 10. That why i did below next
2. I forced close camera app , cleared its data and then while watching on Tv
i placed my finger on Camera icon and repeated opened it and closed it with back key.
since the display on phone was off so i used Tv for help
BUT physically doing the action on phone with fingers not with mouse on screen via mirroring
3. while i was repeatedly opening and closing app by touching the display with finger suddenly i saw camera app asking me for location tags pop up on display and from that time onward there has been no issue and the display is working as nothing wrong happened.
I wish and hope you have resolved issue by now. Please do share your experience for others . since when i had this issue, i found very less information about it. but i saw around 15 to 20 users having such issues especially with Note 20.
Conclusion what i have understood is either its some issue with Note 20 Ultras Camera Firmware or THe Electjet 45W Charger the culprit which i bought for my Tab S7 and was using to also charge my Note 20 Ultra. I have stopped using this charger for my phone and tab and since that day only using 25W OEM charger which came with the phone. I have now this 45w Electjet charger connected via Samsung dexpad which caps its charging speed to 15W.
Here is the link of the video. and i tried all things mentioned and then after exact 24 hours
the display came alive back when doing activities i mentioned above. and i have no link with the guy or channel who posted this video. I was just trying everything to bring life to my dead display .
PS: i had only 5 percent belief in this video . i dont know what worked
i had prepared my mind for the300$ plus panel display replacement.
i just read two recent more comments which state they got their phone working back.
Do read the comments posted as there might be some more clarity of things to try.
(Please Apply reasonable pressure on screen when trying these actions as you might break the Display)

Worked! Slapping it around and massaging it with reboot. Who knew Smack My ***** up! - The Prodigy was referring to modern phone fix'n.

I'm here literally in tears, my keyboard wet typing this because the video actual "Fixed" my phone. I don't know if its a long term fix or just temporary but after 24hrs of a black screen its good to have back a working $1400 phone.
So if this happened to you, dont be skeptical and just try the steps. Last resort is to bring it to a technician or Samsung but definitely try this before.

Fingers crossed it goes strong for the next two years.

Mine went dark about 2 days ago. Been trying the above solution with no success.
But can I ask did you guys hear a slight rattle?

No luck as of yet. Been sat for a couple of hours while watching a film trying the foxes above. No luck.

It just came back on this morning. All I did was let the battery fully drain.
