    i live in the uk and i sent my phone off for this problem twice to carphone warehouse and they sent it back without repairing twice. so then i went to samsung because i thought they would know better that the retailer. and the first time i sent it to samsung, they sent it back with the same issue, the second time i sent it in to samsung AGAIN they sent it back without repairing the black screen issue. i called them up and they said that it is an issue that happens randomly so the problem must not have happened when the samsung technician was looking at it. VERY ANGRY!

    Hello Guys, I have the same issue with my Samsung S5 G906s. Every time I power up the device it boots as normal. I can hear the start up sounds. I am still able to shut it down properly because the touch is still working (I just locate the Power Off and OK portion in the screen). But the LCD won't lights up. Sometimes it lights up but after I press the lock/power key, the issue happens. Do you think the problem here is the loose flex ribbon connecting from LCD to board?

    Thank you

    I removed the display assembly of my S5. The flex which connects the LCD to board is in place. Do not try to open your S5 if you suspect that it is just only a loose flex connector. The flex is firmly attached and a simple drop will not make it loose.

    I am still waiting for the possible solution. But in my case, I conclude that this is a hardware issue. Probably the power supply from the board to LCD is fluctuating or malfunctioning. Or it can be the LCD itself.

    Is it possible to replace the G906S LCD to a normal S5 LCD? Anyone?

    Hello everybody. I bought my s5 on July 2014. It came with all those problems you guys have already told us. In my opinion those problems are related to the android version. My cellphone came with android kitkat 4.4.2.

    What are the android versions of your galaxy s5 guys?

    I really hope that those bugs will be fixed in the next android version lollipop 5..

    Mine is 4.4.2.

    If this is a software related issue, you should have a boot screen during start up. Or you can access the Download (Odin) mode or the Recovery mode. If none of those mentioned possibilities are present, it is a hardware issue. Anyone to contest?

    im on lollipop now and still having the issue, except this time i dont have to take the battery out, when it happens i just wait 30 seconds and when i try again it turns on... still annoying.
    i tried everything literally...
    i reset my phone and used it like that and it still happened i also disabled the stock apps.

    fustration is real.
    dont think its a hardware issue as samsung and carphone warehouse reset and flash hardware reset it multiple times and still not working.

    Dear forum members,

    Since the beginning I was facing the same issue with my Galaxy S5, the black screen problem. Today I went to the official Samsung Service Center in 's-Hertogenbosch (The Netherlands) I prepared a complete case with evidence :-). As soon when I started talking the service guy interrupted me and he told me I had no more explaining to do, it is a known issue! They took in the phone and they will replace the LCD screen, so it's definitely an issue with the phone and it is not software, memory card etc related!

    I thought sprint/android/samsung had this issue nipped in the bud with the last update before lollipop as I hadn't had this issue in months...then I updated to lollipop and now the issue is occurring again.

    I also hoped for the best with Lollipop, but my hope was for nothing, the same issue on Lollipop.... So my advice: Since the phone at least in Europe has a 2 year warranty, go to the official samsung service center and let them replace the LCD screen. And no I never dropped my phone!

    I was having this issue, for me I think it was one of 2 things. I had a cheap case on it that was very tight, so tight I couldn't press the buttons, I took the case off, I also updated to BOC 7, factory reset and cleared cache, no issues since and I was having this issue every day. That was yesterday and no issues today at all.

    First and second day with BOC7 no black screen after unlock screen, BUT after three days, i got this issue again.

    No factory reset in my case, just cleaned cache.

    I am also having this issue. But I have noticed now were a battery pull used to get it going more often than not now when I pull the battery and put it back in and power on I get static on the screen, it usually takes a few battery pulls to get it back in action.

    Is there any form of cure? Sure I could send it back to Samsung as its under warranty but that is a major inconvenience.

    Hi all,

    I think i solved this problem without replacement

    Solution is:

    Settings > Security > Trust agents > Smart Lock (Google)-Off (its on by default) and Pin Windows --off

    I think this solves problem but additionally you sholud close Developer options too.

    Thank you,
    Have a nice day.

    I purchased a Samsung Galaxy S5 five months ago and have had the same issue as many others in this forum. Sometimes my phone takes along time to wake up after being put to sleep and other times randomly when I pull my phone out of my pocket or purse to use it the screen is black. I have seen the same flash of light and then a black screen. The two lights for the buttons at the bottom light up but the phone doesn't respond. Sometimes I have to pull the battery out and other times after a few minutes it begins working. It has been in an otterbox defender since being purchased and has never been dropped. I thought at first that it was my case causing a problem with the sensor, but started playing with my phone and discovered that when I apply slight pressure at just the right angle to the back of the phone or screen that it is almost guaranteed to happen.

    I recently purchased a Galaxy S4 which also has this problem. I have read through this thread with a great deal of interest, and tried various things. I have not solved the problem, but have reduced the occurrences.

    1 - Disable auto-brightness (swipe down notification and untick AUTO)
    2 - When the screen is black, press the power button & release then do this again but slowly - not like double clicking a mouse. Usually 2 - 3 presses will bring back the lock screen. Do this too quickly and the lock screen will just flash & disappear again.

    So far, disabling the auto brightness has done it for me, but like everyone else, I won't be holding my breath! Would be interesting to know if this works for anyone else.

    I feel sure it is a software problem, and probably Android rather than a third party. I am running Lollipop 5.0.1

    Actually, in my case, thus far, I HAVE solved the problem. Keeping the auto-brightness Unticked has certainly solved the black screen of death. If it comes back then - so will I! I hope this helps others out there suffering with this bizzare problem

    Hi all, i am having the same issue with my S5: sometimes when i push the "home" button from standby the screen stays black but the phone is definitely working. I found out in my case the problem is caused from my silicon "bumper": in fact every time this happen (black screen upon wake up) if i lift the silicon case nearby the power button the screen immediately start working properly again. The case DOES NOT push the power button: in some way the additional pressure brought by the silicon cover on the right hand side edge of the phone causes the issue. Hopefully this can help you, cheers

    I've been having the same problem, and I did a cache wipe, factory reset, and different power/home/volume combos, but the screen came back when it was good and ready (the longest time it was out was about 6 hours, during which time I took the phone to Verizon and a repair place, and contacted Samsung support, and nothing helped). The only thing that reliably brings the screen back is to take the battery out, leave it out for at least 10 minutes, and then turn it back on. It's not a permanent fix, but at least i'm able to reduce the amount of time my phone is out of commission. Since this is such a common problem, you'd think Samsung would make solving it a priority.

    I can't turn my alarm off in the morning because all I have is a black screen. It takes hours for it to come back up after charging it. Anyone have an answer? Thanks.
