[Q] [HELP] Phone suddenly freeze and show weird screen

Hi, I have been looking all over the internet and search the xda thread but I couldn't find anything related to my problem.
So this morning when I wake up, I turned on my phone and after I used it for awhile suddenly my phone stopped working (freeze/hang) and started to reboot itself. After it reboots my phone's screen as per attached below.
The problem lasted for a day and started to driving me nuts!
Anyone experienced same problem?
I am running KK4.4.2 fyki.
Thank you very much for your kind help!

are you unlocked, rooted, custom recovery, rom, kernel, anything? can you access the bootloader?

Nope, I am all stock without any modification nor and fancy stuffs.
Just pure android 4.4.2
I am thinking that the hardware might be faulty..

If you're stock, it could be hardware. Though have you ever attempted to root?
Is it just randomly happening?

Definitely hardware

Yes, it just randomly happening. It started yesterday morning until now..
The phone started to not responding at all and then my screen goes broken (same screen as broken TV I might say).
If I let it cool for 15-20 minutes the phone is usable, but then after 1 hour of normal usage the phone started to freeze again.
Just curious, none of you experienced the same?

this kinda looks like the static i was getting on screen on my n7 2012 when i let the battery get too low. charging it up and a few reboots fixed it. but im not sure if that's what is going on with yours

I just got mine, 32gb from the playstore, a few days ago, and nothing like that.
If it's happening when your device is hot | overheating, you may wana see if you get it replaced.

It happened to me once. The phone was with his screen off and when I try to turn it on that exact same screen came. But it just happened once, also I experienced random poweroffs and reboots. I did a factory reset and power off issues and freeze stops, but had one reboot once I start installing my apps. I think its a software issue but I'm not sure.

I'm glad (and kinda of sad) to know that I'm not the only one with this issue.
The problem started about two weeks after I bought mine(Telus). It's done this about 5 or 6 times,randomly.
I found that having someone call me will "unfreeze" the device and the screen gets back to normal.
The first couple times it happened, I was running stock 4.4.2. I since rooted it and installed Xpposed/GravityBox and I'm still getting the problem...
I think that I'll have to return it...

Idk if i need RMA the phone. Its a great phone and the reboot issues has stopped. What should i do?

Hi, I have the exact same problem, I posted a video on youtube /watch?v=m0EkC_ak01g but I got to the same conclusion that it might be a GPU issue. So there is nothing I can do right?, the worst thing is Im in Argentina and LG dont take my warranty because I bought it in Germany. So there is absolutely nothing I can do?, I know how to avoid the flickering a little bit, when I hit "Ok Google" button it seems responsive and as long as I touch the screen it works (you can see it in the video) but as soon as I stop touching it, after 2-3 seconds it becomes unresponsive again, and when I say unresponsive Im saying the screen doesnt reflect what Im doing, I can still push the buttons and all. So Im not 100% sure its a GPU issue, but a software too. Thanks.

Wifi Problem - freezes sometimes and cant disable. Have to restart. LP & KK

Hi guys,
I have a problem that I've never seen or heard of before. So here is the situation:
Power button didn't work, so RMA'd phone. Got different phone back and instantly rooted/installed custom rom. Didn't notice anything until a month later. My phone would randomly just lag out and the wifi would stop. It would still show connected and that there was uploading activity, but that is all. When I clicked it to disable, nothing would happened. I would have to restart the phone, disable it for a while then re-enable it. I though it was the rom so I switched. Noticed the same thing is happening. I decided to play around with my sim, so I took it out and then put it back in, and it somehow fixed the problem. So I was assuming it was the sim causing the problem. Worked perfect for a week then started happening again. I did the thing with the sim and it didn't work this time. I still have the problem now.
Basically, my wifi would just stop working, when I click on it the phone lags out and freezes. I have to restart the phone and it will work. Sometimes Itll work for a full day then all of a sudden just stop. Sometimes it happens just a few minutes after restarting. I mostly find that it happens when the battery is less than 20%. Right now I am running stock LP, locked bootloader. I was supposed to send it in but they wouldn't accept it because I was 6 days over my warranty. So I'm not sure if I was send a faulty phone and now I'm stuck with it?
LG said I would be charged $150 flat rate for them to fix it which sucks. I'd rather just get a new phone and stay away from LG in the future.
Any suggestions? Also this was happening on KK at first then I tried LP Roms and same thing. I have never flashed any radio since I got the phone, could this be a possible solution?

You would get the same reply from pretty much any company, once it is over the warranty period then it is over the warranty period, this is no reason to "stay away from LG". Most charge a flat rate since they're likely to simply do a motherboard/whatever board swap if the fault is to do with internal components, as it is much easier/cheaper for them to do this compared to diagnosing and repairing/replacing things individually.

Try a different radio version. If it doesn't change anything then you have a hardware problem.

The only reason I said I would stay away is because it seems that I sent in my phone with a problem only to receive another one with a different problem. I'll try the radios tonight, hopefully it works.
Thanks, I'll keep you guys posted.

You mentioned that you only ran into issues after a month. During that month a hardware issue could have possibly developed and the device was fine when you initially received it.

Known LP bug.. Thats why i still stay with kk

Serious Battery Issues (after Marshmallow Update)

My G4 got the Marshmallow update in early February and hasn't been the same since. First few weeks were okay and I noticed small improvements in touch sensitivity, responsiveness, and connectivity to my home and work WiFi switched automatically without having to manually tell it to connect. I was happy until...
The last couple of weeks, my battery drains drastically fast, even when it is plugged into various chargers. This morning my battery read 35%, while on the charger. I have been rotating a handful of spare batteries to see if there is a problem with any of them, but they all seem to act the same (including the original battery). I have the sync, location, calendar, and Google running, but little else.
Is this a problem that many are having after the MM update, or could it be something else?

first thing to do if you're having issues after a major update is to factory reset

Thanks, snowrelyt! I figured as much, but was hoping that there would be another fix, so that I didn't have to set up the device all over again.
Lately, my G4 has rebooted itself a few times over the last week or two, so a reset is inevitable... I just need to get the battery above 18% for that! LOL

Deb--Did a reset resolve the problem??? I am just now encountering similar problems, beginning yesterday. My phone went from 98% to 19% overnight, and it was turned off, sitting on the nightstand.
I have four batteries, and a couple of Qi chargers, and I think they are getting a full charge when on the Qi or on the LG charger. However, I just now had trouble getting the phone to fire up, and put in a "new battery" at 92%, and Battery Doc said 60% right after I got the phone up & running.
I hate the thought of doing a factory reset, but if that's what's necessary, I guess I have to. Did the reset solve your difficulty, apologies for repeating that question. Enzo Ferraro, Long Beach, California

Sorry, about the delay, Enzo! I don't get on here much.
I finally got around to doing a hard reset yesterday, because the battery draining was getting too often and very random. I also had a few spontaneous reboots while I was trying to type, so I knew there was no escaping it.

Haha, you're like me: Can never have enough spare batteries (I've got 4 or 5)! First thing I always do is buy at least one or two extra batteries. I tried using different batteries and chargers, but the behavior still happened at odd times, so I deduced that it had to be my G4.

It seems to have resolved what was going on. After a hard reset, I noticed small changes in the look & a few functions of the OS that I hadn't seen before. Also, after Google Play reinstalled my applications, I noticed that some of them looked/behaved differently, although I don't know if a few of them were already due for an update yet or not. Yesterday, I forgot to put my phone on the charger and it was still at almost a full charge this morning. I'll have to put my G4 and the battery through a few cycles though, but it's looking like things are back to normal now. I can only imagine that I most likely had some residual stuff left over from the Lollipop OS that was interfering with the Marshmallow OS.
Back when I had my Windows Mobile phones, I would flash/reset my phone almost every other week trying out new ROMs like it was nothing and I always hard reset afterward, but I have yet to even begin to mess with my G4. I just can't grasp Android's differences that well (everything is still Greek to me) and this is my second Android phone (had my HTC Desire Z for about 4-5 years ). Couple that with how most everyone here uses terms/abbreviations that make zero sense to me (spell it out, damn it! :silly and I just may be on the AT&T G4 ROMs forever!
I hope all goes well for you, Enzo!

I'm getting heavy drain when the screen is on. More so than with 5.1

I just got a used G4 today with MM on it and it literally has the worst battery life of any phone I've ever owned. This sucks.

It is possible to revert to 5.1

S6 Freeze/bootloop out of the blue

So had this phone for a while now and no problems, been running nougat for the past few months, this morning took my phone off charge and placed in pocket. A bit later I checked my phone, it was not responsive a black screen, did a hard reset does the samsung logo then gets stuck either flashing blue or pink. So leave it until I get home, flash latest nougat with odin installs fine, reboots and does same thing freezes at boot samsung flashing blue. Flash it again and now its froze after its said erasing...
I think something has failed hardware wise, any others had this issue?.

Just install "CPU awake" from play store, this will help you keep the device working, this problem is very common in each & every Samsung flagship, starts after 2 year use(won't ever buy a Samsung flagship again), no fix for it, if you don't believe me, check Evey flagship forum q/a section.

That app is useless, in that case completly useless. That app just won't allow CPU's get to deep sleep. But in him case that looks like just next S6 who get hardware broken from unknown reasons

Really? I have a note 4 , exactly same problem, that app gave it new life & not just mine, many note 4 users are using it who are facing the same problem, so, next time instead of just posting nonsense, do some research.

He even cannot turn on the phone, maximum what he can see is SAMSUNG logo so what the **** you are talking about turning on some app on working system?

That's a nand problem, if the device is cooled (I hold mine in front of AC for 5min.), that will help it to turn on & once it's on, install the app & it will work fine but it shouldn't be allowed to shutdown or it has to be cooled down again, it's not a new problem, thousands of Samsung mobiles which ship with faulty nand face the exact same problem, I know it sounds silly, it is what it is & it works(for thousands users)

rifek4 said:
Never before heard bullshits like that. Can you give some link to any information which will confirm that what you told so that a CPU Awake app will fix broken Samsung device? Please about it.
P.S.
I could'nt find anything about it :laugh:

Enough with your bull****, here, take a look...
https://forum.xda-developers.com/note-4/help/note-4-freezing-restarting-t3348821
Read it, on almost every page someone recommended using cpuwake, it's not my problem that you are such a fool who instead of trying to help someone with some advice, would just bash other people who have faced similar issues & maybe know the solution. You can go **** yourself for all I care.

Rishi is correct about cpu awake on the Note 4. It is commonly viewed as a means of extending the life of the Note 4 but eventually the phone will fail.

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.
Intermittents are the hardest problems to find...

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....
