[Q] Galaxy note functional but screen stuck in 'sleep' ?!

Hi Guys,
I have a frustrating situation whereby my Galaxy Note powers on but the screen appears to be in permanent sleep mode - I get nothing but black on the screen.
You can here the Samsung chime as the phone powers up, I can adjust the volume button and hear audible tones. I can also call the mobile from another phone so the underlying phone/OS is working fine.
I can also connect the device via Kies USB and copy images/music with no issues.
I have tried removing the battery and replacing, I have also tried giving the device a full charge however I still get nothing on the screen.
Does anyone know if it's possible to perform some kind of hardware reset to get the screen to power back on? If not I guess i'll need to return the unit
p.s. Stock Galaxy Note
Thanks v much
Jeremy

Same problem for me , i have test many ROM and kernel but i still get the black screen. it's generally when i haven't use my phone during a couple hours.

Same issue here. The screen remains black and not responsive to front button or power button. I still am able to hear notifications (e.g. calendar reminders, plug in power, etc.).
Long press of power button to reboot is the only solution I have found in order to clear.
First occurrence yesterday after owning note for 1 month.
Second occurrence today.
Stock device. No root. KL7.
No newly installed apps prior to first occurrence. I will cross-check to see if any apps updated yesterday.
I have also disabled Green Power.

guys i have been owning note since past 45 days
and suddenly i faced the same problem today
when phone is in sleep and i receive a notification and press the home button
to wake the phone
i see only a black screen with a minute pink dot at top right
and the phone wont respond
however pressing the power button it brings the menu to switch and etc
so i can select power off and then again switch on the phone
guys this is frustrating
please help

Hi all.
My note was replaced yesterday.screen now turns on fine however I'm greeted with a lively green hue and banding! Ha

App update just disabled my phone??

I have an AT&T S5 running stock recovery with towelroot. Phone has been fine today, had 4 apps that required additional permissions for updates today so I ran them. I recall 2 were USAA and Tasker. Also FingerSecurity just got an update prior. After I accepted the additional permissions, I turned the screen off. I then heard it make the lock sound 3 times while the screen was off.
Currently I can turn the screen on or off, however the lock screen never comes up, just the home screen. Everything on the screen is unresponsive and the taskbar is gone. I've rebooted, wiped cache in recovery, it comes up the same way, bypassing the lock screen even though I have it secured with fingerprint. On the 3rd or 4th reboot, I did get a dialog saying systemui crashed. It keeps shifting the icons slightly like it's trying to add the taskbar but they shift about 10 times before finally stopping with no taskbar.
When I long press the power button, I have to be quick otherwise the dialog will disappear.
Is there anything I can do besides a factory reset?

[Q] ATT Moto X 2014 Freezing Constantly

Hello all,
I got this phone about a month and a half ago, and since I got it I've noticed a lot of freezing and crashing (more so after the 5.1 update).
Some examples:
-I try unlocking the phone from active display and the screen goes black. The only way to get out of it is to hold the power button to restart.
-Sometimes the phone freezes on the lock screen randomly, and when I pick up the phone to look at it, the time is wrong and I can't physically unlock the phone, only turn the screen on and off, leading to me having to hold the power button down to shut off and restart.
-When on some apps, like twitter for example, the phone freezes, and I cannot do anything except turn off the screen by pressing the power button. When I try waking the phone, it stays black or sometimes theres a flash of the screen I was on before, and then it goes black again. Only thing I can do here is hold the power button down until "Power Off" shows up on the screen, and I press that to shut the phone off.
Today I cleared the cache, and since then the phone has froze once, causing me to do a hard reset. What should I try next? Any idea what the problem could be?
Thank you for the help.

I have pretty much the exact same thing going on. It started last night... I first noticed I had some charging issues where the phone wasn't charging very quickly after the battery died (after a day of heavy use). I let it sit for awhile, then it booted up, and it showed the motorola splash screen. It gets all the way to the lock screen, although I'm unable to unlock the phone. The screen goes dark. It appears to still be getting texts and the like- although this screen blackness issue makes it so I can't unlock the phone. The one thing I can do is hold down the power button and turn it off. I've tried loading fastboot and doing a factory reset, although nothing appears to happen and it boots the same way. The other thing about it is that it appears to be running hot- way hot. Any ideas? I'm running stock rom, Verizon network, just updated to 5.1 when it came out last week.

Black Screen Of Death. Screen Goes Black And Persists Through Any Type Of Reboot

I have a Note 8 that i have never dropped, had this phone since release haven't rooted. However it is running one of the early Oreo Beta builds CQLB the phone is on Sprint. This has happened once before about 2 months ago and i can almost guarantee it happened in the same fashion as the most recent time a few days ago. It seems while receiving a call i go to reach in my pocket and hit several buttons pulling it out (because of the bulky case) then my screen goes completely black.
(This is where it starts to sound like the normal black screen issue that there are a thousand YouTube videos for)
The phone still makes noises for notifications, rings when calling and other noises like emails and low battery alarm. The screen however doesn't display anything whatsoever and has a blue led blinking.
(This is where it differs)
I've done every button combination i can think of with no avail.
-The regular restart button combination Vol Up + Power and hold for 7-10 secs,
-I've tried to boot into Recovery mode by guessing at what time the Samsung logo should be on the screen and pressing the vol button down several times
-I've tried to boot into safe mode by pressing the Bixby button, power and Vol Up and without the screen displaying anything i can of course not see if i was in Recovery or not.
The screen doesn't display a Samsung Logo, No sprint splash screen NOTHING. The last time this only lasted for about 3 hours and it suddenly came back up when being on the charger and restarted several times. This is now day 3 and after dozens of restarts nothing has worked, on or off the charger. I mentioned the Oreo build because maybe it's linked to that? i haven't had this issue on regular Nougat. ANY help is appreciated and thanks in advance

Try turning off Always on Display. It worked for me..
Actually your problem seems different, so doubt it will work

Kinda hard to do without anything displaying on the screen whatsoever, anyway i mailed it off yesterday for repair from Samsung. It was either that or a 2 hour drive to 12 Mile (Detroit) to bring it to the Ubreakifix store.
Unfortunately Sprint doesn't offer loner phones and can't activate any phone that is non sprint outside of some iPhones which sound a bit strange but now I'm out a phone for 9-11 days :silly:

Have you solved this issue? I have the same issue with my phone. It started happening to me even when I was on Nougat. Happens to me several times already. It goes black screen for about an hour to 3 hours then randomly get back to normal (get notification sounds, can receive call, etc). I am now on Oreo. Everything is stock. Never rooted my device as well.
Tried to bring to Samsung but all they did is 'Software Update' the device which is basically reinstalling the firmware and wipe everything. Service Center sucks and doesn't want to claim it is a defective unit.

My note 8 began experiencing this yesterday and after some frustrations and work around, I managed to pinpoint the issue.
Work around was go unlock phone and drag down taskbar, then click on systems and the system interface would open, after which I could press buttons on lower part of phone and clearscfeen to get back to homepage.
Problem was with Google. In my case I realised when I opened Google maps, the screen went black, so I went into applications and cleared the Google cache and Google maps cache. No 0roblems since.

Is it something with Snapdragon?

Moto G6 turns on, but shows nothing but a black screen

Hello, members. I come here to ask your help because i haven't found any solution for it anywhere on the internet. This is what happened: some days go (around a week or two) i updated my security patch to the last one released by Motorola and the phone was OK, pretty much the same. Then around five to six days ago the problem started: my phone started going off even with full battery, and so i had to hold high volume key + power key for the phone to boot again (this happened twice and was "solved" by the time) and so the headache started. Around four days ago i went to sleep and left my phone charging, then when i woke up some hours later it was completely off, showing nothing on the screen, then i removed the charger and turned it on, and for my surprise the phone booted saying Hello Moto, vibrating and all but the screen showed absolutely nothing but a black/grey screen, not even the boot logo was shown. Once the phone started i noticed the screen touch is working for turning on the flashlight, receiving or rejecting calls and all, but it is completely dark. I have already tried lighting up a flashlight in front of its light sensor to see if the ambient display was active, but it is not. I have also tried turning it on by holding low volume key + power for a lot of seconds and it resulted in no changes. I have tried turning it on by holding high volume key + power key, and even low + high + power keys simultaneously for tons of seconds and NADA. I'm completely desperated because i have found no solutions for it at all anywhere. My phone has not fallen to the ground and neither got watered, so i don't know what the **** has happened to it. It got like this completely out of a sudden, no one even touched it.

I had the same issue with my moto g6 and it happened a few days ago. i unlocked bootloader and rooted the phone and then installed some apps . it happened 2 times. First time happened i solved it. While it was charging screen went black and nothing appeared on screen but phone was working . i called from another phone and it was ringing. I thought an app was causing this issue so i uninstalled some apps that i installed when i got the phone. I turned it off and waited for a while to cool down ( i thought it was heated from over charging ). When i turned on it was ok everything came back. Week later it did the same issue but this time it was completely gone. I removed back cover to check battery . I disconnected the battery and then connected again , turned on the phone , screen was going on and off. After turning it on it stayed around 10 min. and then again everything gone. People who had similar issue are saying hard reset or fastboot mode etc. but nothing appears on screen so how can i do hard reset when i do not see anything on screen. Right now it is unusable . I cannot do nothing with the phone.

I fixed this problem on my G6+
The screen went black after the phone being in the hot sun for a while. I believe the problem was due to a poor connection to the screen because when I pressed hard at the very bottom of the screen the display flickered on. I then pressed very hard at several points along the bottom of the screen and the screen then started working constantly again. Not really a proper fix but I now have a working display again.
