Making a call, screen blacks out, stays out - Galaxy S 4 Q&A, Help & Troubleshooting

Hello everyone, first of all I did a search on this topic, but either I am too stupid to do a proper search or there hasn't been any problem like mine yet.
I also did a little video, check it out.
https://youtu.be/lB3gYQUyL_8
Whenever I get a call or make a call myself (and the moment I press the dial button) the screen blacks out. This may be a solid and reasonable feature when holding
your phone to your ear to not accidently start any other app with it. The problem is that the display stays dark no matter if I put it to my ear or not. It is like the sensor is registering some
sort of object in front of it and therefore gets into "ear on the phone-display shutdown mode". First I thought the sensor was messed up, but then it still seems to differentiate between
daylight and nighttime, because the screen gets darker when covering the sensor with my finger and lights up when I remove it from that spot.
______________________
When accidently having called someone and I want to stop the call, the display had turned black of course, so no way to shut down the call. So I start pressing buttons, like the middle menue button,
and I get to the desktop screen. Still need to shut down the call, so I want to go to the infopanel (upper slide down menue) and the moment I start moving my finger down, to enter the call panel, it immediatly gets dark again.
But there are times when I can access the upper infopanel (without the screen turning black) and see my call being there, but the instant I press on the entry the screen turns black.
Only solution is to quickly remove the battery to shut down that call.
______________________
I have put on a display protector, but it doesn't cover any sensors really.
The problem started with installing CyanogenMod11 and persisted with the latest CyanogenMod12.
Any idea what I can do?
My current install:
Cynaogenmod-Version:
12-20150407-Nightly-jfltexx
Model:
GT-i9505
Android Version:
5.0.2

Screen Lock issue with HD2

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

[SOLVED] cannot hang up during call

I noticed this problem:
when i start a call, my screen become black and i cannot hang-up the call.
anyone with same problem?
another little question:
i have a time-limited data plan (40H /month) is there a way to know if my HD2/WP7 phone is connected or not? or a way to control my data connection?
thank you!
I have the same issue. If I hold the proximity sensor directly to a bright light source the screen comes back on but I'm not always near a bright light source. I've been making calls on my bluetooth headset because that has a hardware hang-up button. If someone could work out how to hook up the hd2 hang-up button this would be a massive help...
EDIT: i make some test, plese discard this post (test result in post #5)
I'm not sure about yours, but after I finish my call I just remove my phone from my ear then the screen show up . Regardless where I am (dim or bright place) the screen responds to the movement of the phone away from my ear .
ok, i make some other test.
confirmed, we have some problem with proximity sensors.
when i make a call, the screen become black. immediately, witoutn anything else.
wen i remove the phone from my ear the screen will NOT come up UNLESS the other part hang up.
for example: if the other part use an answering machine, i am able to record my message, but the screen DOES NOT comes up when i remove it from my ear.
if the other part is a friend, and HE hang up the call, my screens lights up, again, sayng "call ended". then return to the home screen.
if i'm in-call, and i expose the phone to a bright light, the screen comes back too, sowhing all in-call options (speaker activation keypad, and some other things)
Just press the normal hang up button and that should act as the power button to bring the screen back on...

during call this button doesn't do nothing.... already try with all button..
i just play with registry entries, some are interesting.
HKLM\Drivers\Builtin\Proximity
ScreenOffDebounceTime DWORD:50 (Decimal value)
ScreenOffThreshold DWORD:256 (Decimal value)
But i cannot figure how they affect screen (i try to change their value with no effect)
update:
seems i fix it!!!
after an UPGRADE (hehehe) to winMo 6.5, i realize that problem still exist.
then i remove a portion of the screen protextor and proximity sensors works again!
even if i use original HTC screen protector... :\

I've tried that already but it didn't work for me. I did have my screen replaced so I wonder if the problem started then...
Same to me... Is this a replaced screen issue?
Strange one this...the red button (bottom right of the 5 physical buttons) just brings the screen to life for me and should work I would have thought regardless if screen is replaced.
hey guys i am facing a problem too with my tmous hd2...i have dual booted it..when i make a call in android or win7 proximity sensor doesnt turn off the screen at all.....so i end calls without my knowledge and intent.....anyone facing similar issues??? anybody knows any solution???

AT&T S4 lollipop - phone dialer app issues

Since getting the lollipop update, I have noticed that the screen turns on when while I am holding it to my face during a call. It seems to be more sensitive, turns on too easily. Also related I think, is that because the display turns on, my fingers seem to hit the 'hang up' button now unintentionally. So I am talking, screen turns on, finger on side of case maybe barely touches screen... call hangs up.
Anyone else seeing this, any way to adjust this so it stays off until I remove it completely away from my face?

[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.

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...
