[Q] black screen of death - G2 and Desire Z General

I got my G2 for Christmas, did no major tweaking besides using Visionary to temproot to disable bloatware... was texting this morning and suddenly my screen refused to show anything but a black screen. When it first happened there were white vertical lines but now it is solid black no matter what I do. I can still blindly unlock the phone (it makes the sound it normally does confirming this) and then pressing any of the bottom row keys gives haptic feedback like it should so they are still working. I even got a phone call and was able to answer it blindly by doing the unlock motion. I've tried battery pulls to no avail. Holding the volume down button while powering on does nothing; I don't even see the HTC bootscreen. Any advice?

Sounds like it's a hardware issue. Assuming it came from Tmo, call and have it replaced.

Random vibration??

The past few weeks I've been noticing that my DHD often vibrates at random times, when it should not do this at all.
It just vibrates (in stby mode), nothing else but I always think I'm getting a call or a text, which is pretty annoying.
Sometimes it vibrates just once, but also sometimes it vibrates 3 times, very fast and hard. Last night it even woke me up...
Anyone having the same issue?

Had this today when I bought it out of standby. Thought I had a text or email or something but there was nothing. Never noticed it happen when in standby though.
This happens regularly on mine too! its frustrating! you think you have a call or a message but you dont! :s
Its probably caused by your signal going from hspa (3.5g) to 3g to gprs

Isn't this called Blackberry syndrome? Imagining your phone vibrating, just so you can check it!
Seriously though, I dont have this on my DHD. It was present on my Hero though. I think its your phone getting lonely because your not using it.
If you press the volume rocker right in the middle it will vibrate 1 time and sometimes it will do 2 quick vibrates following the first one. This is probably not related to your case but it fits under the random vibration for other that might not know about it.
I noted you get a vibration when you signal goes out, and when it comes back again.
it does happen on mine too...
but i think i know the cause... its usually after using the volume buttons when it does it
but after installing CM, it doesnt do it anymore... i think its something to do with stock ROMS (mainly sense)
+1 more for that, i thought i was going mad when i first noticed it, but after reading this im feeling a bit more sane,
stock rom btw
Mine does it too. I'm using Custom Modaco Rom. When I go to unlock the phone it vibrated but not all the time. Never in my pocket though. I thought it was 3g watchdog playing up but other people getting it too so not that. It did it just now reading these posts hope it doesn't get worse.

Mine does it too. Got used to it now though.
Mine does this, but I know when it does it and why.
Usually it's either when unlocking the phone, or pressing the power button to lock it.
The reason why? It's because I have fat hands and accidentally press the volume down button when using the phone, causing it to go into vibration mode (which makes the phone vibrate once to let you know).
It's confusing, but entirely my own fault.
That's kinda diffirent from what I'm having. Mine does this without going into vibration mode or anything elsr for that matter. It just vibrates, even when locked and when the screen's off...
Just noticed that it does indeed have something to do with the volume buttons. Just lock your phone, press down both of the volume buttons, unlock it and then you will feel the 3 vibrations
I've noticed mine vibrates when launcher pro crashes, happens while i'm listening to music and try changing the volume sometimes, every time it happens the next time i unlock the phone launcher pro has to restart.
Although I have noticed it some times vibrates when I try to lock or unlock the phone and accidentally hit the volume buttons, not sure what happens there though.
EDIT: Just been trying to lock and hold one of the volume buttons, I've noticed it locks up for a second or two, so it's most likely something crashing I think.
Really sorry to bump a thead from a few weeks ago - but has anybody had any luck with resolving this?
This is the only thread I could find on the matter, and it's becoming a big annoyance for me. It's NOT when I go into vibration mode or anything, it can be anytime - even when the screen is off.

I just tried this and you're right - the three vibrations. Perhaps it's by design but I can't see why.
Anyway it's nice to know how to do it on purpose; mind you I used to get it all the time with my old cheap case, with my new case it's never done it "by itself". It seemed a bit odd but I assumed the case was "pressing" both volume buttons when on standby from time to time (makes sense).
I've noticed when i'm putting the phone in my pocket (or out), i tend to grab it on the top with the volume buttons. And yes, it does vibrate when i accidentally press them.
Try it yourself.
Regards, clumsy long fingered dude.
Mine used to do this as well. It would be sitting on the desk not touching anything, screen off and it's just idling doing nothing on stock sense rom, then it would just vibrate randomly a few times. It was a bit spooky and it kept doing it randomly :/
It has since stopped doing that, no real reason I can see why, I have flashed LeeDroid but it stopped randomly vibrating before that.
I'm on AR HD and it's still doing it.
I'm not too bothered, but a fix would be nice.
If I keep randomly pressing buttons on the phone, it will make random vibrations. Sometimes one, two or three. I don't have to press the power button, the phone screen can be turned off, and the phone doesn't go into silent/vibration mode either.
I just played about with the volume buttons now and I got a bit of lag on my phone, lasted for about 15 seconds then went away...

Screen blank on power on

I've had a problem with my E900 since I got it with regards to the screen. I was hoping Mango might fix it but it doesn't seem to have.
Sometimes if I press the power button the screen backlight comes on (i.e. screen goes from off state to powered) but there is nothing on the screen. No amount of button pressing will cause the screen to show anything.
If this happens I have to turn the device off again (backlight then goes off) and try again. Sometimes it can take 2-3 times before it turns on successfully with the lock screen.
I also have this if an incoming call attempts to wake the phone and also alarms too.
Does anyone else have this issue?
I confirm this one popping sometimes. Not that often that it becomes annoying, but nevertheless.
Did you find a solution to this problem? I am experiencing it too and it is very annoying!
I've recently inherited one as well (E900 that is).
The one I have has been dropped, the backlight powers, but no drawing on the screen.
I've disassembled and re plugged everything (bugger stripping down!) but still no luck. I've done a VolUp+Down+Cam+power hard reset, and when I plug into PC Zune says setup needs completing (so it has reformatted) but still no luck.
I cant see anything fried, and no damaged ribbons as far as I can see, any ideas?
I sold the phone a while ago, and never solved the problem. I think it's a firmware issue.

hi.
What do you mean "somethimes if I press power button"?
Is it pressed with purpose to lock the phone, press it to turn off phone (background slider shows to power off - on Mango and beyond version) or press it accidentally?
Cheers.
So, I did a phone reset. Unfortunately the issue is still present!
Sometimes when I press the power button to unlock the phone the screen is lit, but stays blank i.e. no lockscreen wallpaper, no nothing. The same happens sometimes when I get a phone call - the phone rings and vibrates, the screen is lit but stays blank.
When this happens I have to press the power button to put the phone into sleep mode and press it again to wake it up.
What I found is, when the issue occurs the screen is actually responsive. For example I can slid up and unlock the phone then I hear the unlock "pop" sound. It's just that nothing is drawn on it!
I was wondering if anyone else experienced the same behavior and found a resolution. Also I am not sure if this is a software or a hardware problem. If I could confirm it was a hardware problem I would call LG and have the phone repaired or replaced.
i have exactly the same issue as you, it gets really annoying.
i heard from someone online that the only way to resolve it is to replace the motherboard

I am pretty certain this is a hardware issue. I am calling LG tomorrow and hopefully they'll take the phone for repair/replacement.
I sent my phone for repair. Today I got it back, and guess what?!
The issue is still present! It seems, they "couldn't reproduce" or something.
What should I do now?
EDIT: If anyone is interested, here is a video I just captured which clearly demonstrates the problem. http://youtu.be/38kF9RYs_bU
I'm sending the phone back for repair tomorrow with this video attached.
Hey, might not be an issue at all, but in the video, I saw that the two times you were able to get it to go blank you had your finger on or near the proximity sensor. I wonder if there is something that could be the trigger.
Just wondering if you can duplicated it or cause it only when you have the proximity sensor blocked, or if it truely is random.
You are right, it might has something to do with the proximity/light sensor.
On the other hand, this issue occurs even on incoming calls when the phone is placed on a table, screen up and nothing around the sensor.
Today, I visited my local carrier shop and left the phone for repair again. They told me, since this is a second claim they'll run it through the process faster, so I expect to get it back next week.
Will post an update.
UPDATE: My phone was replaced. Yesterday I got a brand new unit, yeah! It was stock wp 7.0. I plugged in my sim and used the phone the whole day, no sign of blank screen issues. Last nigh I installed all the updates (total 5 I think) up to OS 7.10.8107.79, FW 1.0.16.10. Guess what?! Same issue!
I am crushed

[Q] screen no longer working

Phone was working with no issues until the other day. I was viewing a web page and noticed the text didn't look quite right, it seemed to be shimmering. Then a bit later on switching to the camera app the screen was just a lot of green flashing lines, pressing home button worked and then starting the camera again it would either be the same or would work properly. Then later that evening after using the phone fine opening the s cover the screen would not come on but the menu and back buttons would light up, pressing the power button a couple of times would make the screen appear. Then that stopped working as well, and no even then back and menu buttons don't light up. the phone still seems to work as plugging in the headphones and pressing the button on them starts my music playing, but I can't get the screen to turn on at all.
The phone has never been dropped has been very well looked after and is immaculate , there are no scratches on the screen and I can't see any cracks (from a pressure break) either.
Any ideas?
this might sound like im trolling, but did you try turning it off and on again?
seriously, your screen is probably broken. send it to sammys customer service or whereever you bought your phone and let them check and/or repair it

[Q] Unkown touchscreen/text problem

Hello everyone, I have been searching constantly for any information on a problem that suddenly started today with my galaxy s4, and this is going to sound very odd for sure. For no apparent reason, i pulled the phone out of my pocket, hit the power button, and everything that is supposed to be white is pink. The touch screen will work for a split second, just long enough to get the phone unlocked, and then is all together unresponsive. On the home screen, once again, everything that is supposed to be white, (text, notification icons, time, ect) is bright pink. All the buttons are responsive, but the touchscreen does nothing. Upon hitting the power button to turn the screen off, you can see the pink disappear and the screen change back to normal for just a moment before it goes off, same when it powers on, which is why i can manage to get the phone unlocked. Anyone hear of anything like this?
You have either a loose connector or some other hardware failure.

Samsung S8 - Black screen of death already?

Hi Guys,
got my S8 about 6 days ago. it's been working flawlessly and i've been really enjoying it.
Yesterday i took it out of my pocket and the screen wont turn on. it's completely black. i can hear it unlocking, i can even answer phone calls on it and talk, but again, can't see anything. I've tried hard resetting the phone (volume down & power button), it completely reboots, which you can hear the tune of it starting, but nothing. I've tried plugging it into the charger, still nothing.
I'm new to the samsung party, so i did some research naturally and found this was a common problem on the previous generations. Most cases were solved by removing the battery and reinstalling. however with this model, i can't do that. I've taken the phone back to at&t to get an exchange, and because i "preordered it," i need to go through customer service, which they are telling me i need to send the phone back, and because i do not have the original shipping box, i need to pay a 15% restocking fee to return the phone. THEN, they will take up to 5-7 days to send me a new phone. As you can tell, i'm a bit frustrated.
Any suggestions?

Tried it, nothing. I can feel the phone giving haptic feed back and clicking as i click the virtual home button too. I held it for upwards of 30 seconds.

darn. my brothers did that, and that is how he got it to power down. then it powered up normally
have you tried:
Vol up, bixby and power for recovery
Vol down, Bixby and power for download mode

I tried all of that, however, i can't see the screen. So I'm not sure where i stand when i enter those modes. When the phone reboots normally, i have to enter my code manually the first time, which i can do, just by memory of the button placement on the screen, but as i said, can't see anything. I'm willing to try anything. At this point i'm just letting the phone sit idle and let the battery die, hopefully that will do something.
You have a month free of Samsung Premium - sign up for it, call samsung and they'll take care of it

Happy Ending! Cheers

Damn, I got the exact same behavior on my S8+ today! sitting in the couch watching Hockey and I got all excited after the Caps crushed Penguins tried to send a text to a friend but the screen won't turn on? Tried everything above but screen is black..SUCKS!
I just got the same thing ..tried everything ..however the download did work ..and a blue screen came up and asked if i wanted to download so i pressed yes ...so we will see what happens
A friend and I both had this happen within a week of buying the phone. What it turned out to be in both our cases is the screen was on the very lowest brightness setting. We did not set this. Somehow it happened spontaneously. Go to the darkest place you can find and you should be able to return your screen to a normal brightness. I have a feeling this is going to be a recurrent problem with a software fix in the future.
I had a similar issue. I set the power saving option and it looked like the screen turned black. Only after going to a dark room could I tell it was on. It was a new level of dark I never seen even if you consider setting the brightness to its lowest setting.
same here,
during typing screen freesh and black out.
as death as a door knop. nothing worked none of the mentioned options by Samsung relieved me from a black and dead screen.
its now being collected for repair,
lets wait and see
Same here also.
After 7 days of using it I picked it up to check for notifications just to see the black screen.
Never let it fall or anything.
Unfortunately I will not get a replacement from my dealer but a repair. Let's see if we get a BSOD-gate ****storm with this.
Another BSOD here.
Less than 7 days of normal use, screen seems to be deade. I have haptic and sound feedback. Even the alarms are ringing all day long and I can't turn them off.
Now I'm waiting for the vendor to collect it since I requested a return due to defect.
I FINALLY understand what is going on with Samsung Black Screen of Death-- how it happens and what to do.
First off the bat -- IT'S A DESIGN FLAW IN PHONE! Here is what occurs to induce the Black Screen.
1.) As you lift the phone to your ear, the top of your ear touches the screen. The screen "understands" this to be your finger drawing down the "notifications" bar.
2.) If your ear comes off of the screen, when you place the surface back to hear, the screen "understands" this to be a 2nd time pulling down on the screen.
3.) At this time, your screen brightness "slider bar" is sitting smack dab in the middle of the screen. This 'slider bar' controls the brightness, from very bright to the screen turned off. Slide to the left, screen gets dim. Slide to the right, screen gets brighter.
4.) If your ear next touches the screen, it is almost always on the left side of the screen - no matter whether you are left or right-handed. The Samsung S8 + interprets this 3rd contact to the screen as you "instructing" the phone to turn the screen intensity to "off".
5.) You now have the "Black Screen of Death".
You can simulate this with just using your finger on the screen. Pull down the notifications bar ONCE. Then do it a SECOND TIME. You will now see the screen intensity "slider bar" before your eyes. It is the one with the half sun / half moon icon on the left side of the bar. If you move the little blue bar with your finger, going right to left, you will see the screen go dark.
These are the exact same movements your ear traces on the screen as you use your phone to answer a call or to talk on the phone. 3 accidental touches and the screen is BLACK and you don't understand how it happened.
This is a design flaw in the software. Samsung needs to change how the sllder bar controls screen intensity.
If you go into a very dark place, there will still remain a very faint glow from the screen. All you have to do is 2 finger swipes down, then with your finger push the slide bar back to the right- and VOILA -- you can see the screen again.
Hope this helps everyone until Samsung fixes the problem.

Doesn't the S8 have a proximity sensor like the iPhone to determine that the phone is being held up against someones ear?
I FOUND A RECOVERY FROM THIS!!
I just got the Black Screen of Death for the first time after owning the phone for 2 weeks - pretty alarming when the phone is unresponsive, you can't reboot with the power button, and you can't pull the battery. (Coming from an S5, this is my first phone with a non-removable battery). Even though I knew my phone was fully charged, I tried plugging it in, and didn't even get the red LED. Not good.
After a little Googling, the solution I found that worked for me was: Press and hold Down Volume + Power at the same time for 7 seconds.
This brings you to a screen with some options, the first being to reboot like normal.
Volume toggles up and down between the options, but be sure not to choose option 2, which is a factory reset!
The Bixby button selects, so I just clicked on option 1, and I was back in business.
This apparently does a "simulated battery disconnect". Assuming it was some sort of firmware crash, this should bring you back to life. It did for me. There are other suggestions on the page if it doesn't work, but I was back to life after step 1. Hope it helps...
