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

After i hang up on a call (when the phone is in sleep mode and the screen is locked) the screen unlocks. this is quite contrary to what is mentioned in the phone manual chapter 1 page 45. this becomes an issue since i use a bluetooth headset and the phone remains in its sleeve/case and after every call, a whole bunch of applications will launch since the case is in contact with the screen. have i overlooked some settings or are there other owners who have faced this issue?
ideas and suggestions welcomed
did you check it out if any of the hardware buttons being pressed against the case hence wakening up the phone.?
i had it to only closed al my apps in taskm and it stoped flickering
My HD2 is also behaving in the same way even in controlled test conditions - the phone unlocks when a call comes in (I'm presented with slide to accept or reject call) The phone unlocks during the call, but fails to lock again on disconnect (either by pressing "end call" or hang up via bluetooth).
Can anyone verify this? Is it interacting with something I installed?
I believe I found a (complicated) workaround.
What I want: leave HD2 inside pocket, answer calls with bluetooth headset, hang up and phone will go back to lock.
Problem: After I hang up using bluetooth or press the big red "End Call" button or the other party hangs up, the phone stays unlocked! It stays powered on and all kinds of buttons gets clicked.
Practically all lock sw uses their own lock screen (which I don't want to install). CSDevCtrl does not trigger by phone. TouchLockPro uses its own transparent lock screen but can respond to phone events. Using the !SUSPEND for TAPI\Ended under settings does not seem to work when the screen dims about 50 secs into the call.
Solution: Use TouchLockPro together with LockAndOff. Get TAPI\Ended to run LockAndOff will turn phone off, whether by bluetooth, big red "End Call" button, or the other party hangs up.
BTW: I think there is some confusion on whether the phone locks when you
1. press the big red "End Call" button, or
2. the hard "End call" button
in the forums.
I noticed that HD2 have a light sensor next to the top ear speaker.
During a call, if the phone is put near the ear and cover the light sensor , the screen become non-active which is good.
If anyone can come up with a lock sceen using this light sensor , then the problem with random launch of program when phone inside pocket will be solved.
This lock screen should only activated right after an end of call, beacuse , sometime you may want to use the phone in a dark place.

It's the proximity sensor that turns the screen on and off during a call, not the light sensor. How else would it work in the dark? (which it does)

My proximity sensor does not work, when I am getting a call my screen turn off and when I am taking the phone out from my face it turn on only when I am out side at the sun!! the screen stay off when I am inside room. I tested it with flsh light and it is working also.
I have a T-Mobile US version of the HD2. I am having the same problem when using the bluetooth system in my car. After answering or making a call the phone stay unlocked. And then starts making random calls while I am driving!!!!
There has got to be an easy fix for this!!!
Buy pocketshield, problem solved.
i have this unlock problem with 1.48 rom and i solve it by pressing start button and lock. after that everything works fine unless i change theme in settings. then just repeat first step.
Solved
Same trouble with me until I use the following software. I tried it and it's almost perfect. unzip it and just copy to your HD2, run CallerLoc.exe and click Yes, you'll find:when you hang up, or he/she hang up a call, or a call is established, the screen will turn off.
Why say 'almost perfect', the software is in chinese, but the filename is in english. and it's a call location software but with the function we need.
To stop or before you delete the software, run Callerloc.exe and click Yes again.
Hope this will help you. Sorry I don't find a English version of this software. I esure and I'm using this software perfectlly with my Leo.

Greetings.
I understand this is quite an old thread I'm digging up but I need a little help as well and I didn't want to start a new topic just for that.
I've this silly problem, appeared right out of the blue:
You all know the standard manila behavior, when the phone is idle, the screen first dims and after some more time, depending on your preferences, the screen locks. It also locks if you press the power off button. This all was happening to me till this morning.
I added an event in the calendar (the only change I made today) and after that, my phone dims and then goes in sleep mode after the designated period of time, but DOESN'T lock!!! It doesn't even lock when I press the power off button. I can still lock it by pressing Start and then lock or by press and hold the power button and choose the lock phone option. So one would say that it's still operational, so why bother about it, but I kinda liked the standard function and I have to freaking idea why it changed!!!
I'd be most appreciative if you could offer some help with that.
Oh, I forgot to mention. Soft reset didn't solve the problem. Erasing the calendar event didn't either.
My phone runs the factory ROM (1.66.482.1 ELL), I haven't changed anything other than user settings (yeah, I'm a noob... )
Thanks in advance!

Pocketshield could be the end of your problems. You can try it for 10 days and see how it goes...
But why do I need to buy third party software in order to revert my phone to it's original operation?
No, this is not the answer I am looking for. I was wondering if you know of any kind of settings that might have changed by accident and caused this undesired behavior.
Thanks.
The best to return to normal operation would be a hard reset. Or you can spend a while trying.
You can try
HKLM\Software\Microsoft\Shell\Lockscreen\Enable=1
HKLM\Software\Microsoft\Shell\Lockscreen\Active=1
Thank you very much. I opted for the hard reset option... I hope it stays ok this time!
My HD2 also had some strange unlocking and unwanted calling.
I noticed it appeared when using the android style lockscreen.
When I changed back to the original one, problem solved
i had this too. the andriod lockscreen seems to be a bit buggy last time i used it, i accidentially called 7 random numbers
Hi. I'm having an issue with my Verizon S5 where the screen turns on randomly, sometimes a few times a minute, for no apparent reason. Researching the issue, I found a lot of people said the reason they found was that the charge port was bent slightly and after bending it back it fixed the issue. They noticed the screen would behave when it was plugged in because all the connections were forced into their proper places by the charger. However, mine turns on and off regardless of whether or not it is plugged in. I downloaded Wakelock Detector to try to see if there were any apps forcing my screen to wake up but it only listed a couple apps and processes and, combined, they didn't come anywhere near the number of times my screen was woken up. Interestingly, the same day I noticed this problem, my home button also stopped working. It will not turn on the screen when off and it will not bring me to the home screen when the screen is on. I thought maybe it was occasionally functioning, causing my screen to turn on. However, I have never experienced the opposite issue; I have never been using my phone with the screen on and had it suddenly bring me to the home screen. Also, oddly my screen does not have this issue when I am playing music either through the speaker or via bluetooth. If I have music playing, the screen never turns on randomly. If I pause my music, the issue returns and my screen turns on randomly unless I resume my music.
The fact that it doesn't do it while playing music (either over bluetooth or through the speaker) means it must be a software issue rather than a hardware issue. The fact that my home button stopped working at the same time seems to make it seem like a hardware issue but maybe my home button not functioning and my screen turning on and off randomly are both part of the same software issue? I have attached a screenshot of my current version of Android and other details.
Thanks in advance for any help.

Generally, I'd recommend a factory reset just to make sure whether it is or not a software issue.
If the issue is not solved, return the phone.

I was able to fix the problem so I thought I might as well share. I replaced the circuit board that goes under the home button (cost about 10 bucks lol). This is not the home button and cable itself. If you disassemble the S5 to the point where you can see the motherboard, the circuit board at the bottom with the charge port, capacitive buttons, and home button contact is the one I replaced. Hope this helps others with similar issues get working in the right direction. Be very careful disassembling your S5 if you decide to try this route.
Hey guys,
i have a serious problem, which happens really often lately. like 10 times a day. The screen just turns off sometimes. The touch-functionality is still working. I can feel the fingersensor "unlock" the Zuk Z1, but the screen just stays off. Then i try to press all the buttons and sometimes the screen turns on again. But sometimes it just turns on after some seconds even though I didn't touch it at all.
First I thought that this is a hardware issue, maybe a loose contact. But recently a new problem showed up. The screen brightness just goes up to 100%. I turned off auto-brightness and move the slider. Nothing happens. Restarting always fixes it. But mostly after 1-60 seconds it goes back to normal.
Any ideas what might be the problem? Or what I could try?
I haven't rooted the phone and its the newest CyOS version.
Cheers, Oliver
Perhaps you are using the flipcover with magnetic auto switch off when you close the case?

Thanks for the reply,
I havent thought of that before but it is not the cause of the problem.
1. I have a leather case
2. When I take the phone out of the case the displays stays dark
I just did a factory reset today in the morning and the problem already showed up again. So! annoying!!!! Will send back the device I guess
i have lenovo zuk z1 . actually i am getting a problem in this phone . after locking the phone at every seconds light turn on and get turn off on the display. i saw so much on the setting but i didnt get any setting .
The same problem is being arrising with me..please someone help. what should i do..
Hi,
i have tome hassle with the hard press home thing.
Sometimes its working ok sometimes it does weird things.
for instance ... if i press the button hard it some times vibrates , when i let go it vibrates again and its unlocked... thats when i think its working correctly.
but sometimes it just vibrates two times although i didnt let go ...
sometimes on homescreen i swipe the homebutton slightly to clean it a bit... not hard pressing and its vibrating. sometimes one single time sometimes two times in a row .
anyone with the same issue ?
thanks
no one ?
Check what sensitivity you have the button set at. It could be too high or low.
I have mine set in the middle and never have an issue.
i tried severeal sensitivity settings ... sometimes it gets better and sometimes worse... but for me its not satisfying
i think i have to weit for an update or so ...
I had the exact same issue with my S8. Sometimes it just works, sometimes it doesn't detect it, sometimes it registers several hard presses even though I've barely touched it (sensitivity reduced as far as it goes).
This has been driving me crazy for the past week. The hard press function was unusable because of this.
At first I thought it's a software issue (something to do with calibration maybe?). I got an update which didn't fix it. I tried resetting it which didn't work either so I sent it back to Samsung yesterday. Waiting to see what they have to say about it.
The lack of complaints about this so far made me think it's just a weird issue with my unit.
I'm having exactly the same problem and it's driving me nuts for not knowing if it's a hardware or a software problem.
I've googled around and this is the only thread so far. Seems like there are very few people with this issue.
Let me know how the repair request went.
i sent it back also
new one is coming tomorrow ... lets see... will report
I have that issue too. Dont know what to do.

Oh wow, that's really fast. I still haven't heard anything from them. Did they give any information about what's wrong (hardware/software)?
no ... i didnt sent it back to samsung.
i bought it from amazon.de and ordered a replacement.
thats faster
it will arrive today then i can sent back my first one...
same here, having issues with the home press function .
I also send it back to the shop where I bought it
I´ve send mine back to the webshop also. My mate got his s8 2 days ago and his hard press was perfect and responded smoothly all the time. So i guess it must be a hardware problem.
Will share more info when i get feedback from the repair.
Same problem here, sometimes it works, sometimes (when the device is in standby) it works only after several tries and pressure in different spots.
Can someone who has got a new device or sent it to repair report if it is better now?
Hardware issue... my replacment Works fine now
Same problem
I have this issue also. Mostly it works, but sometimes it doesn't work and the phone hesitates to come back to life. If I press the power button after hard pressing the home button or just wait 5-10 seconds, the screen will come on. Oddly, when it doesn't work (and occasionally when it does), the small vibration thing happens. I have this turned off, but sometimes when hard pressing the home button, I get the vibration, but the screen won't come on. Other times, I get the vibration and the screen will come on. Mostly I don't get the vibration and the screen comes on. Annoying.

As i said ... it seems to be a Hardware issue. Get a replacement
Mine does this often, i personally could care less for the home button function so I set the sensitivity to max and yet at times if I barely touch the home button area it acts like I have hard pressed the button.
Sent from my SM-G950U using Tapatalk
I have the same problem maybe even worse. To me it looks like it is accumulating presses, the more times I press the button the more times it vibrates. So at the end I sometimes get 4 or more vibrations for just one press. Sometimes after I lock the screen it vibrates by itself and turns on the screen.
Looks like I'll get mine replaced ASAP.
Got the same issue once in a while.. also have a faint red glow on the screen. Considering getting it replaced but dont want to wait for a replacement.
Hi, I just got my Galaxy s8 about 3 weeks ago. I've had very little in the way of problems with it. Well, except one thing... Everytime I make a call on it the screen will wake up at random. It doesn't matter if it's a call from the installed phone app or hangouts. I thought this might have something to do with the apps edge so I disabled that. Didn't fix it. I thought it might be the home button so I put it on the lowest sensitivity. Didn't fix it. I frequently call while laying in bed (who wants to hold a phone up all the time?) so the phone is between my head and a pillow. When the screen wakes up it clicks and than shuts off after five seconds because I turned on the keep off when in pocket or whatever it's called in settings. Before I turned that on the screen would stay on and buttons would get pressed usually ending up with me ending a call. I still think it's the home button but I'm not sure how to fix it. It anyone has any ideas or has the same issue please let me know.

Its the proximity sensor.

Proximity sensor is working though.. I have no way to test it properly but if I place my hand near it the screen goes black and when I move it it lights up again. It also doesn't make the click
Had this bug on every device
So it's just a bug? No fix currently? I'm just wondering because I haven't seen anyone talking about this specific issue before ¯\_(ツ)_/¯
I'm also suffering from this issue
