Look up android sleep of death. I had on previous devices but not the note 13

I actually think it does wake up just not turning on the screen , i can hear the volume changing , and the device going to mute mode , but screen is off .
or maybe i am wrong and its normal to change the volume with the screen is off on samsung devices?

It isn't normal no, the only button that should work with the screen off is the screen on button. I'd start by looking into what shaun suggested above and if you find no fix, maybe just try a factory format? (back your data up first).
I get a slightly similar issue on mine but I got the bug when I flashed Hyperdrive Rom, my screen occasionally "goes off" but it's not really off, I can see the back light still. I just have to screen off/screen on and I'm fixed. Your issue sounds different though because you need forced reboot.
Hope you get it fixed, Good luck!

did OP ever get this resolved? I am having the exact same problem with the 10.1 2014. Screen goes to sleep, but when pressing power, or opening the book cover, the backlight does not turn back on. You can see the image on the LCD in the light and hear screen presses, or volume adjustments.
Tried factory reset, and Odin'd a fresh rom.. No go

I got rid of my bug by turning off airview in the pen settings, ive been stable since then. Wouldnt harm trying it?

I am on stock rom and never rooted. Mine started doing the exact same thing. You can see it on in the light. Factory reset didn't fix.

Hi,
I have a quite similar problem. It started with a charging problem so I thought changing the cable would solve the problem but no. My charging is kow ok, but each morning after a long charging night, my note n8010 with stock android gets SSSSSSLLLLOOOOOWWWW . Black screen, then slowly wakes up, but need 10sec to unlock screen and unusable... I have to force reboot too.
It seems like it doesnt want to wake up, like extreme energy saving mode... ?! No solution actually found for me

The only fix for me is flashing Boefla kernel

[Q]Screen doesn't turn off when locking

Hello everyone.
I have a couple of problem with my xperia Z3. The problem is that when i press the side button to lock the phone, the phone get locked but the screen seems to be still on(and then turn completely off after a few seconds) . I mean that even if the phone is locked it's like i am seeing a completely black image. This doesn't always happens with Android KitKat but with the Lollipop upgrade i made yesterday flashing a generic Baltic firmware, the problem got worse! When it happens the screen stays on even after few seconds and it doesn't turn off and i'm forced to restart the phone to "solve" the problem. If it helps, when the phone locks fine the screen turns off immediatly but when the phone has this problem when i press the lock button i can see for a moment the screen locked, with the clock, the padlock icon, the fast dial icon and the fast camera icon ecc and then the screen turn black(but still on) like "something is slowing/blocking the phone from getting locked"
The second problem that i have is that sometimes when i make a call or recieve one when i put the phone to my ear the screen doesn't turn off and the tousch screen still works making me end the call unintentionally touching the screen with my ear for example. I haven't had this problem yet with Lollipop, but I used to have it with KitKat. Anyway this is the less important problem that i'd like to solve because even if the phone should work proprely by itself i can always accept the call and then lock the screen with the side button "solving" the problem of unintentionally ended calls. But the first problem really bothers me a lot and i'd really like to know how to solve it.
Does anyone have at least one of this two problems and knows how to solve them? Thank you !
I'm sorry for my english and i hope i've explained myself well. I've just restarted the phone so the problem at the moment doesn't persist but the next time it will happend i will make a short video to make you see exactly what happens or if you think that this two problem could be caused by an app just tell me and I will write you a list off the app that i've installed.
**Edit: I'm really sorry, i haven't read that this was the wrong section for questions, could someone move it to the right one? Thanks.

Galaxy S8+ black screen?

Hey there,
I have got a Samsung Galaxy S8+,SM-G955N.
Some days before,my phone was stolen by a thief,then I asked for the police for help.The police found the phone for me in the end.
I was so happy at first for my phone was survived.But then I found my phone's screen is always black.When I connect my phone with the wireless charger and charger,I can hear the sound of connecting the power,and I can hear the notification sound,when someone calls me,I can hear the ring!And "hi,bixby"also works!I wonder why?!
I have rebooted so many times,and tried to reboot the phone to recovery mode and download mode.I ended up with failure.
(My phone has been flashed a custom ROM and TWRP.My phone has a lock screen password and lock screen protect which means you can't reboot and power off.)
I really don't know what the thief had done......But my phone wasn't fall off from high places I can be sure......For the phone has a perfect body.)
Then I tried many times to reboot one day the screen recovered! But I found that the screen is not stable,which means it has many bars,it will disappear and then appears at another zone.Just like the old TV set.
I want to wipe /data,then I rebooted to recovery mode.But.:crying:the screen then do not working...... Just like before.
Then I tried many times,I entered the recovery mode.The screen works in the end,but the colours seems very strange,a little purple.and the touch screen don't work at all.I used the mouse to swith the brightness in TWRP,but when I turn the brightness to over 80% or lower than 40%,the screen looks dark.I can hardly see the contents.
So I want to ask you all for help,is this a hardware or a software issue?How can I solve it?
Thank you all and I love you all!!!!!!!!!:crying:
I am a student......And I am so poor.....
Thank you all again!!!!!!!!!!!

I'm hoping you have warranty. Seems like you have done a thorough job at trying to problem solve. I'd head to a repair place for a quick confirmation and maybe repair.

seems like a broken/damaged flex in the screen

Oneplus 6 Black screen, but system sound works.

Hi, yesterday i faced problem with my phone. 3 mounths old, no any root, no any unlock bootloader etc. It went into black screen and was working just vibrations. So i was looking for any solution. After long searching i found MsmDownloadTool V4.0. Everything ok. But now i hear just system sound, when i pres the power button. Vibrations working, sound system working, led working. Is that mean my display is KO?
Sorry for my english, im doing my best.

Amazon fire hd 8 (7th generation) problem pls help

Hello , I had this problem for a long time now and I have looked for a lot of possible solution and none worked with me
I was watching a video normally when suddenly the screen stopped responding to any touch I tried holding on the power button to restart it and it did restart but the problem is still there , I even tried factory reset which you can do only with the use of the buttons ,and it also didn't work .
I have disconnected the battery and reconnected it and nothing also
the problem went worse when I disconnected and reconnected the screen digitizer or what I think it is . the screen went off totally , there is only the sound , the sound of the tablet starting and also the volume buttons make a sound when I press them as I think it's the sound going up and down .
I don't know what is exactly the problem , but I'm sure disconnecting the screen digitizer made it worse so take that in mind .
I hope there is a fix as I can't get it back to amazon ,thanks

Seems to me that your hardware is damaged, replace the hardware with new parts, then reflash your stock firmware. Then flash TWRP and root the device.
