I bought my device (P600) a few month ago,
and suddenly (without changing rom/karnel or doing root) i got a big problem -
when i push the button that close the screen(turn off the screen but the device is still on) or if the screen is turned off automaticly, the screen stay off forever. Even pushing the power button doesnt turn on the screen.
The only way to turn the screen on again is to reset the device (by pushing the power button long press).
I almost sure that the problem is a hardware problem even that it's look like a software problem because after i saw the problem i changed the rom and the karnel to other option to check if the rom/the karnel is the problem and the problem didnt solved.
Someone have a clue which element make the problem?
Thanks (and sorry for my bad english)

I'd bet money on it being a backlight issue.
Test it again in a well-lit room with a bright lock screen wallpaper, something with a lot of bright color. Once the screen turns off, wake the device and look carefully to see if you can see anything. You might have to tilt the screen, but you should see a very faint, dark image.

Amazing that's was the problem!
There is a way to fix it? What is the component that causes this problem?
thank you so much!

Unfortunately I don't know of any solution other than sending it in for warranty coverage or replacing the screen yourself.
I've seen a couple of other posts on XDA involving the same issue, but never saw a solution. I've even seen this issue a couple of times IRL (not on my device, thankfully) and have not been able to find a solution. The two times I've seen this issue, the backlight level could not be adjusted, either. Whether it was set to automatic or manual brightness, it would never adjust, the backlight was locked at a constant level, until the screen turned off, and then the backlight would NOT come on again until the tablet was restarted. Reflashing stock firmware and doing a factory reset did not help, either. On one of those devices, the backlight DID start working again for a while after a manual wipe of internal storage, but only until the tablet was restarted, and I think that might have been a coincidence, I was not able to replicate that again.
So in short, I'm afraid I don't have a good solution other than hardware repair/replacement via warranty.
this has just happened to mine - will have to send it into repair, but it had CLEAN ROM installed so they might argue re the Knox trigger - really annoyed about this!

hi,
does anyone know how i can set it so the screen auto locks after a given amount of time or is there a freeware app that can do this please. because i rather have it that having to remember to press the power button to lock everytime, sometimes i might forget.
cheerz,
snoop
Lock the Screen? Power-Button simply switches the Device of, e.g. the screen. In Power Management you can set a Device timeout in Battery Mode and on AC Operation. This is equal to pushing the Power Button
I think i see the problem, or i'll tell my problem with that issue...
When you push the power-button the screen turns off and is locked, but if you receive a sms or so, the screen returns back on and is not locked...
ok ye i think u get my point.
i dont know about screen lock after receiveing sms or call.
but i c the point of samson, pressing the power botton does lock the screen.

look for deviceock or vj devicelock.
There is a today-application called BatteryStatus. With its help you can lock the device automatically when it is shut down. Does the job for me - of course you allways have to unlock the device after turning it on.

If you had bothered typing 'BatteryStatus' into Google you'd have seen it was the first hit. Establishing it is the right program is simply a case of reading the web page. Why are people so goddam lazy these days?
yes ok i get your point. sorry.
right i have installed. lots of nice options and things. but have little problem now. As we knw the device has the function where as the backlight will turn off after a set amount of time. Mines set to 30sec for battery power and 1min for external power.
After 30secs (using battery) it does its job and turns off the backlight. Normally i would press the power button and device turns back on. HOWEVER! since installing batterystatus the device just wont turn back on. I mean its got enough battery, i can tell this because 1) the light at the top flashes 2) Heres the strange thing , the only way i seem to be able to waking the device from backlight is by pluging in the usb cable.
So i thought i would try and un-install the app see if that would help..but nope that didnt help because it still does the same thing.
After installing the app i did a soft rest. I thought it might help, but it didnt. This is the other thing, once i did this, i see the t-mobile splash screen where shows the ROM and other info. And then i just goes blank for a while....and then i see the T-mobile PIN entry keypad splashing by every few secs. I was only able to by pass this after trying and trying to enter pin number on a black screen.
Do you think i should do a hard-rest? Dont really want to do this. Means i have to re-install my little apps and contacts, email settings etc etc.
Can anyone help me with this problem please??
Hi there, i had quite te same problem, after a soft reset the backlight turns on until the bootup screen dissapears, then the screen seems to be blank, but it shows everything, but without the backlight on. You have to point a light onto the screen and you can hardly see wats on it.
Then go to the backlight settings and turn it up.
Then you have to look at every program, thats adjusting the backlight settings and turn of automatic darken screen or so in the program.
That helped for me.

And :S stranger thing was that the problem didnt happen this time, i saw the t-mob splash screen, saw the windows mobile green splash screen and then my keylock and then pin number screens.
hmmmm no idea wots that was all about. but hey its all working K.O so im happy now. just got to fiddle with the settings now
Thanks againt to everyones help. Appercaited

So I have had this pretty serious problem going on with my LCD screen. This problem started happening after I flashed a new ROM (I think).
My LCD screen is working fine, however, after I turn the LCD screen off for the first time after rebooting (by putting it to sleep by using the power button or any other method) the screen will then never come back on. I know the phone is still on because after I press the power button to wake it back up I can still press buttons on the phone and I can hear noise from the phone like I normally would. The phone is on, the LCD just will NOT come back on no matter what I do.
Another weird thing I have noticed is that when I go to adjust the brightness of the phone it does not change the brightness at all even though I am adjusting the slider on the phone.
I have tried about 4 different ROMS (including stock) and they all have the same problem. I tried disabling the light sensor through the advanced configuration tool, but that did not work either.
Does anyone have any clue how to solve this? Thank you.
there was another post about the same issue a couple of days ago, if it wasn't for that i would of said there is a problem with your screen. Go to this thread and read the last post.

Like I said in my post I already did this and it did not work.
My screen's backlight would not work after i press the sleep button.It would respond because as I randomly scroll through the screen I can feel the vibration of the touchflo and if i hold the phone up steady in a certain area with enough ligh such as the glare of the sun I can partially see the screen but its very hard. Only after i reset it the screen would come back in and the backlight would work until it goes into sleep mode after being inactive. I have tried installing a new Rom but it still didnt solve the problem. What do I do to repair this? I was assuming it was the flex but then I thought if it was the flex the screen would not work at all ? Can somebody help me

I'm assuming you aren't asking where the backlight controls are. It seems like you're saying that the backlight simply doesn't come back on after putting the device to sleep.
If you are flashing custom ROMs, preform a task29 (search) and then re-flash the device. If this doesn't fix the problem (make sure you test it before installing anything.), flash the latest stock ROM and see if it continues. If so, see about a warranty repair/exchange.
If this is on a stock ROM, re-flash the latest stock ROM and see if this behavior continues. Test it before installing anything. If it doesn't clear up, ask your carrier about a repair or exchange.
I have a Note 8.0 N5110 that has a strange problem which I don't really how to troubleshoot. When I am using it, the screen will go off just as if I short pressed the power button. I'll press the power button and swipe the screen to unlock. Everything is just as it was when the screen went off, but now the menu, power, and back buttons are non-functional. There are no lights or haptic feedback when I press them. My device was previously rooted before the 4.4.2 update and I had to use odin to install the upgrade. The issue didn't start for a couple of weeks after the update. Once the screen blanks and the buttons become non-functional, minutes later they will start working again; however, at some point, the screen will blank again and the cycle repeats. I have restored to factory settings with no luck resolving the issue. In fact, the screen will blank while I'm still in the setup phase. I really don't know what to try next to resolve this problem and my device is pretty much unusable at this point. Any thoughts or suggestions as to what I could try to fix this? Thanks in advance for any help - Jeff Gaiche

Couple questions.....do you have a case or screen protector on it? Sometimes these can interfere with the sensor and cause these type of issues.
I do have a case on the device. It's been cased pretty much since I purchased it. I guess it can't do any harm to remove it from the case, just to see if it's possibly interfering with a sensor somewhere. The issue does seem to have been sporadic at first. I'll give that a try. Thanks for the suggestion -- Jeff

Was just a thought. Otherwise it might be a defective sensor that has to be replaced. Not really sure.
I had the same issue. In my case the buttons still worked if I used the spen. I went back and wiped both the cache and Dalvik Cache*and it resolved the issue.

Hello. This is my first thread, I have downloaded maybe hundreds of ROM's from this site, have read thousands of threads and of course bricked a few phones lmao. Now I am here with a REALLY confusing problem. Without further ado, let's dive in. sry for my bad english btw.
I bought a second hand S9 today. The guy whom I bought the device told me, when he turns off the screen of the device by pressing the power button, black and green lines appear when he turns on again, and after a few seconds, when he turns the screen back on by pressing the power button, the problem disappears he told. I think he said there is a problem in the part called screen flex. (I ain't sure what that is, I need info about that too.) Sorry if you're confused this far, cuz more is coming thru
I got a very useful APK file named "OLED/AMOLED Saver" and installed it on my device, it worked really well and the lines were almost invisible anymore. After a few hours of use, what I noticed was even more confusing. I activated the AoD (Always on Display) feature, coincidentally, while testing the screen, when I locked the device by pressing the power button and the clock appeared on the AoD screen, when I turned on the screen in that way, I noticed that the screen did not burn in as if it was brand damn new. But if I don't wait for the AoD screen to show up and immediately press the power button again, the screen turns on completely and something really, really terrible appears, a mixture of black and green. Now let's come to my questions, I've blown your mind a lot I think.
1- Can anyone explain what's going on here?
2- Is the problem in the screen flex or is it purely software? (AoD thing)
3-Is there anyone who has experienced this and was able to completely solve the problem?
Thank you for spending your precious time. Hope I get a solution..
Hello, I have same problem with my old S9, it seems that is fully hardware issue, as a workaround you can set full brightness - it causes this issue to appear less frequently and another option is cooling down the phone - when display is black/green just lock the screen and put your phone to the freezer for a while - it will work properly until it heats again
Its something about an update made by Samsung https://eu.community.samsung.com/t5...t-bars-black-screen-issue/td-p/1745470/page/4
