I've come up with a problem that has perplexed me on my Galaxy J700T. I've looked everywhere for solutions, but none have worked.
The phone's screen will go dark after it boots, but will show the lock screen for a split second. The screen will sometimes flicker back to life for a moment, but then go back out. This can happen a few times. Sometimes it will go back to the same screen, but sometimes it will show the lock screen. Sometimes it will show the lock screen on a flicker, but then go back to whatever normal screen or app it was on before, when I hadn't unlocked it. This only happens when it was on that screen previously though It sort of Flashes the lock screen I suppose you could say. The phone's screen seems to be unresponsive when it's black.
I'll start with what I know:
It isn't solely a hardware issue - The screen does turn on when you first turn on the phone. It shows the boot process. You can boot it into Download mode and the screen will stay on. You can also boot it into Recovery mode and there will be no problems with the screen. The phone can boot normally and the phone will show the whole process. The problem is post boot so I find it hard to believe it's solely a hardware issue, otherwise I should have these problems in the other modes too.
The screen isn't always off - I've managed to actually catch my phone displaying messages at the bottom of the screen for a split second. One such being that it has connected to the internet. This will show for a split second, while the rest of the screen is still dark. The screen appears to otherwise be dark with no light, looking as if it is off.
I've looked into this black screen of death issue I've heard about. I'm not sure if this is it. I've never had the issue before with any other android device I've had. It doesn't seem like it when I look at descriptions of the problem.
I have put the phone through Factory Reset, which hasn't worked in stopping the problem. As soon as the welcome screen shows up to set up my phone, it will go black again. I cleared the cache. I Cleared all data and reset it. Rebooted it in different ways. I did root it.
Would anyone here happen to know what's going on or have any possible solutions?

TL: DR: Screen sometimes is totally black, but otherwise the screen seems to work fine. Sometimes the phone acts completely normal. Sometimes the phone acts completely normal, but the screen is tinted green, but only after it's booted up. I can access download screen with no issue, most of the time I can get into recovery with out a problem, but not always.
I'm brand new to the GS3, but I purchased it last week on ebay (described as fully functional) since my other phone has been giving me troubles. I received it last Thursday (5/15/14), and it seemed to work fine. I have not been able to activate it yet since I did not have 4G sim card, so I've just been playing with it around the house to make sure it works until I get my 4G card from Verizon in the mail.
So Saturday comes along, and I notice that the screen is all black, but makes the usual sounds when you touch the screen. I pull the battery, and boot it back up. The Samsung logo would come up, but none of the boot animation. Nothing after the Samsung logo. It seems that if I push the power button, the phone seems to be functional, but nothing comes up on the screen. Sometimes if I push the power button a bunch of times, I can get the screen to come on. The screen looked normal, and everything worked fine, until I hit the power button. Back to the black screen. I booted into recovery, cleared the cache and did a factory wipe, and it seemed to be completely normal for a while.
I've noticed that sometimes phone acts completely normal (proper colors, screen turns off and on as it should), sometimes it works normally but the screen is tinted green (power button turns off and on the screen as it should), and sometimes, the screen is totally black, but the touch functions work normally.
Since the screen always works at boot (I can see the Samsung logo clearly and with no color distortion, but sometimes the rest of the boot animation is gone, even though I hear the boot music), and there is also no color distortion in recovery or download mode, am I likely looking at a software issue?
It is not rooted, and completely stock on 4.1.2. EDIT:Baseband is VRBMF1.
I have tried to make my problem as clear as possible, but I will clarify anything if necessary.
Thanks.
I downgraded to VRBMB1 with ODIN, and I still seem to be having the same issue (screen goes black, won't come back on), although the green tint problem hasn't happened yet. As long as I leave the screen on, it works fine. I'm thinking that this might be a problem with the power button, although I don't understand why it would allow me into download mode with no issues, but trouble doing much of anything else. I'm probably going to be sending it back for a refund, but if anyone has any suggestions, I'm more than willing to listen. Thanks.
This issue make absolutely no sense to me, and only started yesterday.
First, I am stock, unrooted, no mods, no crazy sideloaded apps, just a good old Nexus 5.
When I go to wake the phone, I have noticed that the lock screen is 100% unresponsive. I cannot enter a pattern lock. I then switched to a PIN lock, thinking maybe there was an issue with the pattern. Again, unresponsive screen. So I took my screen lock off completely, thinking there is maybe an issue with the lock screen in general. Again, even with no lock screen, I cannot swipe screens, open apps, nothing. This also includes the soft keys at the bottom.
I decide to factory reset my phone. I update only my Google apps, and again notice the same issue. The screen is totally unresponsive, but then 2 white lines will flash at the top, and the screen will work.
Once those white lines flash, the screen is completely responsive like normal, there are no other issues until the phone goes to sleep again. Sometimes the little lines flash 2 seconds after waking up, sometimes 30 seconds, sometimes I have to hard reset the phone.
I also am linking to a YouTube video that I recorded of the issue in case I am not making sense.
So can anyone explain this to me? What could cause this issue on a phone that has never been rooted or flashed or anything?
Thanks in advance for the help!

Weird. Issue. Maybe you should stick everything from your sd to your pc.
And flash a factory image from fresh install from here - https://developers.google.com/android/nexus/images - if you're lucky the drivers maybe corrupt and not the hardware
Sent from my Android 5.0 Nexus 5
Could also be a loose connection. Maybe the flex cable to from your screen wiggled its way out a bit. I've never seen that before on any phone. I'd back everything up and flash a factory image. If the issue persists, contact Google and see if you can RMA the device.
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.
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.
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.
