Problems with the LTE version - Galaxy Note Pro 12.2 Q&A, Help & Troubleshooting

Hello,
I have been experiencing the following problems on my Note PRO 12.2 LTE within the past 2.5 months. I have never dropped the device. Is this a hardware/design fault? I have performed factory reset several times already. What suggestions do you have?
1. Sometimes there are strange garbage/bar code-like images on the screen. Mostly appearing in the middle of the screen (mostly bottom part near the home button, sometimes at the top and in the middle).
2. After sleep (by pressing the power button lightly), the device does not turn on. Sometimes I have to press the power button/hold it for over 15 times for it to turn on. Sometimes I have to wait for an hour or so and try again before I can turn on the device.
Thanks

Looks like a screen defect. Possibly a loose cable. Best send it in for repairs, it should not be doing this.

Thanks. Do you think the 2nd problem is caused by a screen defect as well? For example, the unit was actually turned on but due to a screen defect, nothing showed up and I thought it were off.

It is certainly a likely possibility.

It seems that the first problem only occurs when I use Yahoo Mail app. Could this be possible?

Sent it to Samsung for repairing today. They found that it was due to a LCD fault. They exchanged the LCD screen for me. Hope everything will be fine.

Screen burn in

I have screen burn in on my Fuze. The two soft buttons and the bottom 2/3's of the scroll bar are visible when they shouldn' t be. For example, click on a reminder at the top so that the screen goes black with the next screen allowing you to choose if you want the reminder, wireless info, etc... At the bottom I'll see the soft keys and program select scroll bar in a gray tint.
I guess I need to leave a white image on the screen for an extended time to undo the burn. But I've only had this phone for a few weeks...I've never had burn in on a cell phone and surely never this quickly on any monitor.
Something similar happened twice to me.. It faded out slowly.. now it's ok
You may check http://forum.xda-developers.com/showthread.php?t=447891
Funny now it's gone after having it turned off for a couple hours. I'll post if it comes back after I have it on for a bit.
It's Back!!! only took one power on cycle and let it sit there for a couple of minutes :-(
kind of scary.
Is it still under warranty?
Weird but believe me - it is a software issue. Restart will always help

Yes, I'm going to get them to do a warranty replacement. I had another fuze that had a different issue (bad sound) that I replaced after 30 days...it never had this issue.

I think the part of the reboot that "fixes" it is the screen goes white for a while which helps clear it up. But a few minutes later its back.
The same happens for me, but not very often.
It must be a software issue, no need to replace your device.
BTW, It's definately not a burnt in screen.

It goes away easier if I use the SPB Clock and put it on the white clock...plug it in...set power options stay on 10 minutes when plugged in.
So it is an LCD type of burn it (it appears) as it goes away when a white screen is forced upon it. I think the pixels in that part of the screen don't change very often so it gets a little memory that needs to be "washed" away. Odd thing is my last one never did it. So I think some LCDs are better quality then others.
Its happened to me twice and both times its gone away.
Its good to hear its a software issue, I was worried it might be hardware.

My first Fuze had this problem. Sure I flashed a lot of roms but each rom displayed the same result for me. After getting a new device, the problem never occurred again.
If it was software, it would be doing on everyone's device in the same place or region. This is a hardware problem, no doubt in my mind. The same rom on 2 different phones would yield the same results if it were software related.
If your phone displays this type of "burn-in" then take it back, exchange it, whatever. My new phone has been perfect and works as it is supposed to.
Unusual Events?
Were there any unusual events that led up to the screen-burn in? It is odd that they would go away and come back like that.... did you try flashing another ROM?
Saw this 'burn in' a couple times too. Was scrolling the touchflo3d and went to the photo and videos tab. Once in camera mode I noticed faintly overlay 'album' and 'slideshow' on the view finder. But the 2 words couldn't have been burned in as its not normally on that tab. Probably some weird software driver issue.

[Q] Nexus 5 screen showing colorful static

Has anyone come across this before? I was watching a video on MX Player not too long ago, and it seems to have resulted in a permanent colourful static for the phone.
I can't really tell if it's doing anything, but when I go through the motions of resetting it or booting into bootloader, the screen does not change at all.
Interestingly the volume buttons are still working, and if I press the area of the screen where I think the buttons are (e.g., the back/home/programs buttons) I get the right vibrations. Which leads me to believe my screen is broken, and that it's a hardware fault. I'm hoping pretty hard this isn't the case, as my phone is only two months old and it was a replacement for a 6 month old Nexus 4 which had stopped charging.
Anyone come across this before? I'm hoping there's a kind of solution somewhere out there... To make matters worse I bought this phone via a parallel importer AND I'm currently overseas and won't be back till the end of January.
Sigh. Photo of screen is as attached - please forgive the terrible quality as I had to use my laptop webcam.
Thanks in advance, everyone!

Only time I've seen something like this was when my integrated graphics card on my desktop overheated, everything still worked, but colorful static everywhere. I'd let it cool down for a while, chances are it was pretty hot when it did that, and see if high temps might make it happen again.
I just had the same thing happen. Phone had been in my pocket and I had just taken it out to check the time maybe 10 minutes before it happened. The only difference with mine was I bumped into a table and hit the phone in my pocket. It does have a case on it and there is no sign of damage at all such as a cracked screen or anything. The static only lasts for a few seconds and thats right after I force it to reboot. After that it just goes to an all black screen. My LED indicator light is still flashing at me telling me I have an email though so I'm not sure what the deal is.
Were you able to resolve this issue? I too just experienced this issue as well and my phone is currently unusable. Thanks!
Do a full wipe as in wiping the entire phone and making it as if you just got it out of the box. if it persist RMA

Hi, I broke my screen (really bad smash) and had have this static on my new screen. The new screen was apparently fully tested. When using the slim port i can display on my TV and the digitizer works fine, its just this same colour static on the handset. I am now waiting for a replacement USB flex (it was a bit bent in the break) and i expect the new USB flex will fix it. If not then its a bad screen.
Will post the results when i get the parts
Fixed!
Hi,
My new USB flex arrived today. I installed it and found my screen is working perfectly.
The first pic is the same colour static that the op had.. Second one is the USB flex board / ribbon. Ebay for 20 Euro. Please remember that USA users are LG D820 and Europe/rest of works LG D821. I think its important for this part as the aerials connect here ans they are different in USA.
Good luck everyone

Static screen and freezing
Hi All,
Need help here with my 6 month old Nexus 5. It has been pretty good with no issues but since last evening, it started behaving weird. The chronological events are as follows
1. While browsing on Chrome some websites were not scrolling intermittently. This was only in the browser.
2. After about 10 mins of the above behavior the entire phone froze and didn't release itself. I had to force reboot by holding the power button down for about 10 secs. When the screen came on, it was the static screen
3. I again pressed the power button a couple of times but no use. Held it again for 10 secs, then phone rebooted and everything was fine.
4. Continued to use the phone and everything was normal until this afternoon, when the phone again froze while browsing a website
5. Since then the phone screen shows the static and if I press the power button once, the screen switches off and press again the screen comes on with the display showing properly. I can now only perform one touch which is registered and the screen freezes. If I switch off and on again the next screen / action is shown which is the action I did in the previous touch. Every time it registers one touch and I have to switch off and on again to see the next screen. Sometimes the phone just shows static and I have to wait a few seconds (30 sec) before using it again.
6. If I make a call to my phone, I hear one ring and then it is busy tone like I've cancelled the call. However the phone does not show the incoming call.
My phone has been intact and is well protected with screen guards and case. There is no physical misuse / abuse of the phone. I managed to shut down the phone and enter recovery. Here as well it only registered one touch, though the phone was processing and moving the next step. I somehow managed to initiate a factory reset through the settings, but no use.
Now in about 2-3 hrs the phone has become completely useless. I'm uncertain what the problem is, all my touch inputs are registered and processed. The screen just doesn't refresh to the next and requires a power off/on. I picked up this phone in the US and now in India. So I can't RMA the phone and I don't have warranty for this in India.
Any suggestion will be greatly appreciated.

I'm getting the same issue. Tried soft and hard reset. Opened her up and seated all cables. The issue is still persisting. Is replacing the USB flex the way to go?
Hey I have a nexus 5 32GB and the screen started to do weird things and now it isn't working at all. Its the same in recovery mode also do I think that it's not a software problem.
I think there is an issue with the motherboard. Please help me out.
Thanks in advance.

Same thing, Screen now black. Won't turn on...
Hey everyone, I know that this is kind of late to the thread, but I have what I believe is the same problem as everybody else here. I had my Nexus 5 in my pocket for maybe five minutes, and in between the times that I put it in my pocket and took it out again to reply to a text, the screen went all colorful and static on me (Red tint, almost as if I had twilight on, but I didn't). I tapped the back, and the colors went back to normal, but the digitizer wasn't responding to touch. Then, It went black. No color, the speakers weren't working, neither was the backlight on the display. I took it apart, and figured its either the USB flex cable (which looked frayed), or the mainboard. If its the USB flex cable, then I know I can repair it. If it's the mainboard... well, as a sixteen year-old who has no current source of income, I'm out of a $400 phone.
Pictures attatched. Thanks!

I took the phone the LG service center and the technician seemed to know this issue and immediately said that the USB flex cable needs to be changed. The entire fix took about 5 mins and the phone is working fine since then.
Sorry for the delayed response.
I hate to necro up this thread but I'm having similar problems to the op with my nexus 5. About two weeks ago I saw my screen get grainy just like the op and many others mentioned and then the screen went completely black. The screen still "turns on" but it's just black with the backlight on. I can hear notifications and other things and I'm hoping that all I need to replace is just the flex cable. If it's a problem with the logic board then I'm screwed basically.
Anyway that's my story. Bought the flex cable and it'll be here by tuesday so I'll find out then if I'm lucky or not. Fingers crossed.

Hey man, did you ever try this out and get it to work? I have the same problem and was thinking of trying this out but wanted confirmation first.
Thanks!
Just wanted to post here to say that this thread just saved me a lot of money!
Had the same issue (static showing on the screen). Local phone repair shop told me it needed a new screen, without even looking at it(!), and it would be £120 + labour. Told them I would think about it, and came home and did some more research, found this thread. Ordered a replacement USB flex cable from eBay, and fit it by following a YouTube tutorial, and now the phone is back working fine. brilliant!
Thanks xda!
I had a problem where my screen looked like an old CRT TV with particles flashing all over on anything with a static dark background. Any ideas

N5 in bootloop - possible hardware fault related to power circuit

Hi guys
Unfortunatly my time has come to have a possible hardware issue.
Yesterday my N5 was connected via USB (like I usually leave it resting at work / charging) and out of the blue, rebooted. Google logo shows up, and reboots right away. Trying VolDown + Power shows up the menu but I hardly have any time to select bootloader or recovery, and when I do, it eventually reboots again after a couple seconds.
I'm able to turn it on and have it on if I avoid touching the power button, when I do, sometimes it works (screens just turns off), sometimes ir shuts down after a few seconds after doing so. It's not always, but happens three out of five times.
Connecting the USB cable has the same behaviour, sometimes it's alright and I'm able to copy files and so on, sometimes it shuts off and there it goes into bootloop again.
So, I got home, opened it and I looked like a donkey looking at a castle lol. I had a disconnected brown wire on the right side of the battery which I was able to fix, but that doesn't seem to be the cause of the problem.
The power button feels ok, it's not exactly rattled or anything, it has on/off feeling. if you know what I mean.
Problem is, I bought this in second hand in london about 6 months ago, would be hard to RMA and probably they would give me the finger.
Anyway, suggestions? Anyone went through anything like this? I doubt it's a software issue (rom) cause the same behaviour happens when on recovery / bootloader. Sometimes it holds on and lets me do things, sometimes it doesn't. Most often, doesn't.
Any help or tips are greatly appreciated.
Thanks guys.

I can't, was bought in second hand in a shop, besides I opened it and the water sensor is pinkish (never touched water, probably humidity).
I can only do that around christmas time.
Any other tip ? Something I can do before considering something like that?

By sending in for repair or replacement, I meant to LG. Not Google for RMA.
LG will charge you for the repair or replacement.

Screen randomly turns off but phone still on, backlight often stays on

Hey guys, i'll try to explain the situation as best i can below, hopefully someone can work out what is wrong.
My phone is about 16 months old. About 2 months ago i dropped it twice within the space of a couple weeks. There were a few cracks along the screen, however it wasn't very noticeable and i wasn't going to bother having it fixed. The problem started a couple of weeks ago when i went to grab it out of my pocket, however i found out the screen was black and it wouldn't turn on. I don't really know how to describe it but it was acting very strange...
- The screen would have white/gray bars all over it then turn off, then it would do the same with very thin vertical lines that were white/gray/other colours...
- When i get the screen on, it generally turns off again within 30 seconds, however it can stay on for a few minutes.
- If the screen is on and i press the lock button, it almost certainly won't come back on.
- Restarting the phone or holding the power and volume button nearly always gets the screen to come back on. It often then restarts but turns off again shortly after.
- The phone is otherwise still working when the screen goes off; the notification light stays on and i hear messages etc coming through
- The backlight often stays lit, revealing a gray screen opposed from total black. Sometimes it does not stay lit however.
- When the screen came on it was often unresponsive to touch
I had the screen replaced yesterday by a phone repair shop and the phone is still not right. I have factory reset the phone and also wiped the partition cache. Other than that it is still not working. IT seems to be working better... The screen always seems responsive to touch when it is on, and it doesn't seem to be turning off as often. It generally starts up and works fine when i start up by holding the power button and down volume button together... However even still it sometimes just flashes up with a few thick white/gray and black lines on the screen..
Does anyone know what can be causing this and how i can resolve it? If you need any more information please let me know and i will try provide it. I could try get some pictures of what the screen is doing when i finish work. Thanks guys, i appreciate any input.
EDIT: I managed to get a pic of what i mean by the thin vertical lines all over the screen. This just appeared when i tried to restart the phone after it the screen had once again stopped working. The imgur link is gIFMGD6
Anyone have any ideas?
Hey, did you ever figure this problem out? My phone just started doing the same thing. Can't find much info about it.

Yeah, i had the screen fixed hoping it would fix it, however that didn't work. Turns out it was the motherboard, don't know what was wrong with it in particular other than it was simply going faulty. Had someone replace the motherboard on it for $50 and have had zero problems since! Hope that helps you.
Thanks for the response. I tried replacing the screen too with no luck. Unfortunately the same place that replaced the screen said it would cost $400 to replace the motherboard!!! The phone cost less than that so it looks like I'm gonna buy a new one.

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.

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.

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....
