Progressive Situation on screen - Galaxy S6 Q&A, Help & Troubleshooting

Hello guys! There is a progressive issue on my phone which i couldn't be sure of the source of it.
I was using my phone with enes' ultimate nougat romhttps://forum.xda-developers.com/galaxy-s6/samsung-galaxy-s-6--s-6-edge-unified-development/rom-ultimate-nougat-s8-port-t3681259 for over a year now. It was working like a charm.
Then recently some horizontal lines started to show up. At full brightness lines are gone, but as i lower the brightness lines comes and covers almost all of the screen and after some time of usage with low brightness lines dissappear.
And a couple days ago while browsing on chrome suddenly all of the horizontal parts of screen started to shift up and down(like the url tab which is located up top shifted to the all the way down) then screen went black. After a day it opened by itself as if nothing happened, working fine. Later on same thing happened. I tried to open dowload mode and recovery, phone was responsive as it was vibrating and notification led blinking, but screen remained black and flashed with fade lines. Interestingly i am able to see my files on the computer and odin is detecting the phone.
I have searched about the issue but couldn't find a valid answer to this, some said it's the screen, some said it's the hardware(graphical unit), some said it's software. Can you guys give me your opinions? Thanks.
(btw i tried to upload firmware via odin but odin did not even pass setup connection step)

[Q] Nexus 5 display corrupts after boot

My Nexus has a display problem and i'm trying to troubleshoot what the issue is and I'm wondering if anyone could help as it's not obvious where the issue lies.
What happened is I was using it as normal this morning and then the screen started flickering to different sizes/colours until it finally just went off. It was almost like it is trying to find the correct refresh rate and the colours appeared polarised at one point. After holding power down to reset it, the google logo appeared and then the spinning dots. Once the boot was complete the android logo appeared and then as soon as the main screen was displayed the display cuts off with a white pixelated mist and shuts off. The phone is still running as if I connect via HDMI I can see everything as normal however the phone responds extremely slowly. I can get into recovery however the screen quickly does some strange things, it flips like a mirror and cuts 1/3 of the screen off.
I'm not sure if this is a LCD problem as its a replacement from ebay that I've been using for a few weeks now. I would suspect that before anything else however it's odd the pre boot logos display fine. I've checked and cleaned all connections however it's still doing it. I'm running stock 5.1.1 rooted.

Screen goes partly black

Hi all, I've got a weird problem. The last 3 days my screen has been acting strange. Phone is working without problems when suddenly the hardware buttons won't respond any more. After a few seconds the screen goes black and stays black. Buttons are still lit, but don't respond. But the strangest part is that the drawer stays visible and can also be used normally. I mean, I can draw the notification area down and let it fill the complete screen. So the screen itself doesn't appear to be broken.
Also, when putting the phone to sleep and awaking it again, I can see the normal screen a brief moment, maybe half a second before it goes black again. Restarting the phone is the only thing that will help...
I've cleared Dalvik/cache hoping it would make a difference, but it did not. Hope someone has got a clue?
I've uploaded 2 screen shots to show what I mean.
I'm rooted on OxygenOs 1.0.3/Android 5.0.2.

Black screen and dead for few minutes

The first day allready 2 times black screen out of no where and afther that no reaction on any buttons.
The first time i waited 10 min or more then the S7 reacted normal again.
The second time i pushed the buttons....
The only reaction is when i press the same time: powerbutton, homebutton & volume button down.
Has anyone the same problem?
I had that issue once with the home button. I had to schedule a reboot through the craptastical built in scheduler that is says it is supposed to optimize the device. Search for restart in the settings.
I have the same sort of problems. All in all the s7e seems very buggy to me. Random crashes (especially in oculus app), sd card is sometimes not recognised and after most reboots I get two error messages (one about touchwiz and one about system proc). I'm not sure what is going on.
My wife's is a black too. I had a similar issues with my s6 last year it was the brightness had been swiped to low in my pocket, I was able to barely see the screen in a dark room and turn it up. No such luck with her s7. Hope someone can offer an idea, I'm headed to Verizon later if I can't fix it myself.
S7 black screen
Verizon did a reset for my wife's S7 to fix it hold down volume down, right side button, and the button on the face of the phone together for 15 seconds. The phone came right back on with all apps and stuff intact. Hope this helps, they said this wasn't the first S7 to come back like this they think it's a software glitch.
Im having the same problem....

Try turning off the App Power saving mode!! This fixed the black screen problem on my phone.
I've got the same issue (sometimes 4 times in an hour, sometimes it doesn't happen for 2 days..!!).
I've tried fixing by doing a factory reset and turning app power saving mode off.
Unfortunately this did not fix the problem. Yesterday I got an unresponsive blackscreen again :crying:
Any ideas how to fix this problem?
This happened two days ago with my wife's S7 Edge. She was using it to text me about dinner plans after work, her screen shut off, and it wouldn't work for several hours. The thing was getting very hot. When she was home and charging the phone the screen started working again for a little while, but with several green stripes down the right edge snd aa flashing horizontal band of grey near the top overlaying the screen image. Then when I tried plugging it into my computer to use Samsung's Smart Switch to roll back from the update she had accepted while at work the screen died again. It has not come on since, not even the stripes, and blue or red LED lights once in a wwhile at random. I managed to use Smart Switch to wipe the phone's memory. Then the program took several hours to download something very slowly and install that - a whole new OS update? That completed, and now the charging LED works correctly and the green stripes and grey band are back, flashing rapidly when powering on. Otherwise no screen function. She is shopping for a new non-Samsung phone now. Ridiculous.

Galaxy S6 screen flickering

Greetings.
I've recently been struggling with a problem with my Galaxy S6 and I've searched far and wide on the interwebs for a solution, with no avail.
You see, whenever I turn my phone on, or wake it up from the lock screen, the screen flickers one or two times, but doesn't always turn on.
They keys are active, touchscreen is active, but no image.
Sometimes I have to try and unlock my screen two or three times to get an image, sometimes it turns on after the first flicker.
An example of what I am experiencing is at https://www.youtube.com/watch?v=CyiDgpUSkaE
[edit] Another example is this: when switching the display brightness, the screen goes to crap and starts flickering like crazy, and at minimum brightness text goes unreadable and small (video) https://www.youtube.com/watch?v=HIMFaCy_KVY
I am not rooted, everything is stock FW, I had android 6 stock and recently upgraded to 7 stock OTA and the same issue persists.
I cannot access download mode or recovery because the screen won't turn on. Only time it turns on is when Android is booted. Even when booting, the blue led flashes because the device is booting but I have no image.
Please contribute with some ideas, I cannot wipe cache from recovery because I can't see anything even if I try to boot recovery (or download).
Thank you in advance!
Did you resolve this issue? If so, how? Mine started to do the same after a short fall. My initial thought was hardware but I can get into recovery and the screen functions just fine there.

S6 Dead - only download (odin) mode available

Hi guys. My little story about my SM-G920W8 (original firmware) :
I went to a waterfall boat cruise and my phone got wet while I was taking some pics. It didn't fall into the water; it only got some spray and that was all.
A few minutes later it started to behave weird, like the buttons were pressed randomically, and weird stuff appeared on the scream (three keyboards kinda overlapping each other, horizontal colored lines, green rectangles, etc). I didn't turn it off and 5 minutes later the phone screen went black and the blue LED got on.
After that the phone got irresponsible at all and stayed with the blue LED on until the battery was dead (+- 4 hours later). I charged it again and nothing happen, until I tried to turn it on in different modes. The only thing that worked was the download mode.
Since I need to recover some pics from this cruise, I tried connecting via usb and using ADB; No success: the phone is detected by the computer (samsung drivers are installed), but "adb devices" doesn't show it at all. I'm not 100% sure, but I remember turning the debug mode on prior to the accident because I was developing an app for it. The phone has been into the rice for the last 2 days, but nothing has changed.
My questions:
Is there any chance to recover the pics from the phone? What else should I try to get ADB working? Is there an alternative for ADB to access the files?
