Samsung Galaxy S8+ - Cannot unlock phone due to "Black Screen of Death" - Samsung Galaxy S8+ Questions & Answers

Hello everyone,
I hope this was the correct place to post this; if not, please feel free to move it.
I have a Samsung Galaxy S8+ (SM-G955W) which worked perfectly fine one day, then the next the screen no longer shows any display at all. The strange thing is: the phone still functions properly. It still rings when I receive a call and still vibrates when it receives messages, however the screen itself remains black and does not respond to any touch at all. According to the internet, this is often known as the "Black Screen of death".
Troubleshooting attempted:
- I have performed a soft reset multiple times by pressing and holding the Power + Volume Down buttons which forces a restart. The phone does indeed restart - I can feel the start up vibration and the blue LED light does remain on while it powers on. I then feel all my messages arriving to the phone however at no point do I see an image.
-I have let the battery die completely, then charged it back up to 100%. Unfortunately, after powering on the phone once more, there is still no display.
-I have taken the phone to a local technician who informed me that the screen is not broken and the back lighting appears to have no issues. He believes it may be a deeper issue with the phone.
*I should also mention that the phone has no physical damage to it - it hasn't been dropped, no water damage, etc.
At the very least, I would like to unlock the phone to plug it into my PC and back up my photos, documents, etc. Unfortunately, as the phone died and was powered on fresh, I cannot unlock the phone via my voice or fingerprint as the first unlock Android insists must be the pin. I attempted Google's Find my Phone but it only allows for a remote factory reset. I tried Samsung's Find my Phone which allows remote unlock however it apparently needs to be enabled on the phone settings before it can be used (Who'd have known that before encountering the need to do this...).
I am unsure what to do. Can the phone be repaired? Can I at the very least unlock it without using the screen to reach it's storage and backup my files? Please help

Was the phone dropped in any way? Sounds like the LCD is not displaying and the digitizer isn't registering your touch. Take a decent flashlight and shine it onto the screen and look for minor cracks. If cracked in any way I would look into replacing the screen assembly

Thanks for the reply! I'll take a flashlight when I get home from work today to take a look. Assuming there may be a crack somewhere, do you know of any way to unlock it and access the mass storage to collect my pictures/documents?
Edit: Even if there's a third party software that can do this? I'm willing to pay if necessary. I've tried "Dr. Fone" but the software is outdated and does not support the S8+ model. I should add I don't believe USB Debugging Option is on

If USB debugging was enabled you could use ADB to potentially recover the files. Pressuming you're already connected the Android to the devive it'll have autborized the RSA key.
You could also use an OTG cable to plug in a mouse, but since you cannot see the display at all, that won't be very helpful.
I found this software with a quick Google search. Haven't used it myself.

Thank you again for your assistance - I will download that program tonight and let you know how it goes. Also - do you think an OTG cable with both an HDMI port and a USB port would work? I'm hoping that I could use the HDMI port to view the screen on a monitor and hopefully use the mouse to unlock the phone that way. I've tried a USB-C to VGA cable but that doesn't seem to show anything on the monitor. I'm not sure if that's because the lock screen remains locked...not sure. I will keep you updated.

Where do you get such an adapter? I've seen micro to HDMI. But I've never seen two options (mouse & hdmi ) on one OTG adapter. That would be really nice

Hmm...looks like that guide requires USB Debugging to be enabled which, unfortunately, I do not believe it is. I also have stock firmware so no custom recovery installed either. Due to the snapdragon chip, I wasn't able to root my phone so I couldn't do all that (at the time)

Also - that adapter is right here: https://www.amazon.ca/dp/B07QXW8KYW/ref=pe_3034960_236394800_TE_dp_i1
I've already ordered it hoping it can do something...but the USB-C - VGA didnt work so I'm not feeling too optimistic about that.

Now that is nifty!!
Let me know if that works out. The amazon listing states that it works for S8/S8+ and the seller is being responsive to the reviewers and offering support. Only 64 reviews in total on the product but it seems promising. Fingers crossed for you ?

Thank you so much for all your help - I received the above linked adapter and attempted it but unfortunately it did not work. We tested it with another Samsung Galaxy S8 device and it worked perfectly. This leads me to believe it isn't just my screen that is not working...perhaps the issue is a bit deeper than that. But the adapter itself worked great!
I installed the software you linked however it was just the Dr. Fone application which I mentioned in my opening post that it did not support the S8 or S8+ model. It only have the option to Factory Reset my phone which unfortunately defeats the purpose. I'm unsure if I have any options left...I've researched for hours. Any final thoughts or ideas would be appreciated
Thanks again for your assistance so far, you're the only one who's attempted to help.

Urgent. Touchscreeen off

I am on vacation in the usa and bought a note 10.1 at best buy in san diego. Now i am in los angeles.
Today i played a little with it and found that the touchscreen does not respond as expected depending on where I touch the screen. (Fingers not pen!)
In the middle it is spot on, but above and below the registered touch position is way below where i actually touched the sceen. Especially when more than one link is at these positions i always miss the one i want to click... also when typing a text sometimes i hit 'c' but space is registered. Additionally i tested with multitouch visualizer from the market and clearly see what i described.
I also own a galaxy tab10.1 and never had this problem., so i guess i am not dreaming this.
0. I guess there is no way to calibrate the screen?
1. Can you use multitouch visualizer and test if your device shows also this behaviohr, please? Want to now if it is normal or if my device is broken...
2. In two days i fly back to germany. Should i return it? Never returned something at best buy. Is it problematic? Do i have to explain much or jisit easy going? Should i say that it is broken or just return it?
Thank you very much!
Klaus
Ps: you can also use the developer menu and turn on visualization of touch stuff. Here i see also that in upper and lower part of the screen the registered position is off .
Don't take a chance. Return it 1st thing in the morning. All you need is your receipt and explain the problem. Get a manager if you need to.

You should be able to exchange it or return it. At least go there and take it with you.

I think i will return it for a refund if possible. Because i fly back on saturday i do not have enough time to test it (i also want to do a little sight seeing here ).
Forget the BS that I wrote. The problem was because i was charging at the same time. After unplugging the note and using multitouch visualizer again the problem was gone. Stupid me. Sorry for polluting the forum with my crap
I have noticed an intermittent indication of the same thing especially when playing Monopoly. Sometimes I also see an intermittent delay when touching the screen today in SNotes I saw at least a second delay from when I started a line and the line showed, but it is very intermittent.

Have to admit, I was surprised at your post, but given the time constraints returning it seemed logical. So glad it turned out ok.

[Q] Busted TF700 Display?

Hey all,
So recently the display on my tf700 went out for no apparent reason, just tried to unlock one day and nothing would show up. I can tell that everything functions via a microhdmi to my TV, and that the digitizer works great. My only issue is that there are currently no replacement parts of any kind for this kind of issue for the TF700 specifically. I've seen that there are some replacement LCD/Digitizers for the tf100, 200, etc. but I'm pretty sure that the enhanced resolution of the TF700 screen makes it different from the others. (Or am I wrong?)
So at this point I am debating whether or not to sending it in to get it RMA'd, but the problem with this is that the tablet is unrooted and unlocked.. I've heard some people on this forum say that their bill comes out to some obscenely large numbers due to a motherboard replacement for having their tablet unlocked and I wouldnt want to send my tablet in just to have some ridiculous bill for a minor issue. (just like everyone else)
I'm probably going to try and pop it open sometime this weekend and take a look inside to see if its anything incredibly simple that happened, which I hope it is.. *fingers crossed
tl;dr : Has anyone else successfully fixed a display issue on a TF700 specifically? Has anyone tried to send in their unlocked tablet with this issue and had to deal with an expensive bill?
I have seen cases where ASUS would repair tablets free of charge. But its not "No strings attached". From what I have seen ASUS will re-lock your boot loader and the unlock tool will not be able to unlock it again. However, I think that it maybe fixable using the "fastboot oem unlock" command. Also, if its just the screen then it probably wont cost that much. The cpu and the motherboard are will cost you if they have to replace either of those. I hope this helps solve your problems.

One other thing, if your tablets hdmi works then its probably just the screen. So, that would probably cost under $100 to replace.

[Q] Micromax A110 Touch Automatically working

Hi Guys,
I'm facing this issue where my touch is automatically working. The touch automatically open an app and doesn't allow the user to type anything.
See the attached video. Seems like others are also having the same issue as I found this thread but since no one came out with a solution, I'm creating a new thread.
Let's find out a solution to this problem as a lot of people are facing the same issue in particularly to micromax phones. Also don't suggest solutions like going to the service center as they have worst of the service. They had my phone for 3 months and ****ed it up pretty badly

HTC u11 issue

Hi all, my new phone which I have owned for nearly a year HTC U11 64gb had a fight with the car door and lost. Lines running down all colours so cannot see any apps or able to answer the phone when it rings I can unlock the phone as I have fingerprint setup but do not have USB debug activated. HTC have advised £120 plus any additional parts that may be required if I don not want to go ahead I have to pay a £27 charge for them examining the phone, but prior to even looking at the phone they will restore to factory.;
Is there any way I can get all my personal stuff off photos videos mainly and documents, when I connect the phone to PC it bongs once but there is nothing in My Computer, my knowledge of computing is very limited so need help please.
Also will the HTC U11 life screen connect onto the board for me to gain access and copy what i need and back up the phone, the U11 Life connector looks the same and I can buy the screen for under £22 delivered where the U11 5.5" is coming in at £55.
Hope you tech guys can help.
Cheers
Size matters
The screens on the u11 & u11 life are different sizes. That alone will cause it not to fit... Working with mobile devices for years I will say there will most likely be other issues (cable, pins, size of cable/width) even if you just wanted to use a screen temporary for data transfer.. in the US a screen for a u11 costs $55-60 on eBay I suggest just getting the correct one for the u11 standard.
---------- Post added at 06:52 AM ---------- Previous post was at 06:48 AM ----------
Another idea is from another post, using an external display on your device ( if your digitizer works )

Fast wireless charging problem

Hi,
When I put my note 20u on the wireless charger (not from Samsung), it shows fast charging and after couple of seconds it goes back to normal wireless charging. I have tried with 3 different chargers (all can charge at 10w) and cables but the results are same. I am not using any case, but a snake patterned skin (similar to dbrand Black Swarm). Anyone having the same issue or know why it is happening?
Thanks

Since I normally keep up with reading the posts that others have made I can tell you this has already been mentioned and there wasn't any resolution to it as far as I know. I personally always wirelessly charge my phone because I don't want to mess the battery up constantly using super fast charging the difference is that I have Samsung's actual wireless charger for the Note 20 Ultra so I actually don't have that problem at all and I'm thinking it might have something to do with 3rd party chargers.. I don't know if there's been any resolution to it since the last time I saw it so if you search for the thread post you should see what has been said so far.
