[Q] Can't access phone during call, need help! - Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot

Whenever I start or answer a phone call, my screen goes black and will not turn on until the other person hangs up. I just recently found on my ROM that I can set the power button to end the call so I have been using that, but I cannot use the keypad to type passwords and it is very frustrating. Any ideas on what could be wrong? I am currently using the Black Edition PACRom for the s4, but the problem also happened when using the standard cyanogenmod. I am thinking that maybe the proximity sensor is screwed up but I am just very frustrated about it. Any help would be great!

I think it is the proximity sensor, I had the same issue and what I did is to replace the glass and making some enlargement near the proximity sensor in order to have more blank space around.
you can see it in the photo.
With stock rom, things goes find, now the screen goes black only if i place it on my ear, but with custom rom, i can not hang up calls even if i press the hang up button, call still continuing.
Sorry, if my english is bad, i am a french speaking.

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.

Same for me
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

[Q] Screen goes blank during call[NOT standard feature]

Hey you guys!​
I Just bought a used HTC Legend, got it rooted and is currently using Rodriguezstyle MoDaCoMoDrOm V2.3 Fix Vivid Sense ROM and I'm loving it!
BUT!, when somebody calls me or I make a call, the screen goes blank, I know it's a standard feature, BUT when the call has ended the screen wont turn on again! I have tried pressing the power button and all the other buttons but nothing happens, the when i press the home, menu etc. fast after eachother the phone vibrates like its actually alive just with a turned off screen.
I have tried other Roms, same problem
Can i turn the "blank screen" feature off somewhere?
Sorry for my bad english, I'm a Dane :b
seems like the proximity sensor on the phone being block. are u using any 'bumper' or casing? ever try removing it?
anyway, to ur ques: nope. not aware abt turning off the feature but i like the feature. it prevent user from accident tap anything when doing a call.

WP7 End Call Issue

Hi Guys,
I have been having issues when trying to end a call with the new WP7 Rom. I also used to have this when using Andriod Roms.
When I go to end a call, pressing the end call button does nothing apart from light up the keypad. I've tried pressing every button but nothing but the keypad lighting up happens, the call never ends! I have to remove my battery and switch the phone back on to get the use of my phone back.
I have :
HardSPL 2.08
MAGDLR111
Radio 2.15.50.14
Any Ideas?
Thanks,
Jon

Did you not try the end call on the screen? Not the hard one on the bottom right of phone
Russ
The screen turns off when making a call so the touch buttons are not available. This is why I have to remove the battery as I have no other way of bringing the display back to life. Obviously if I make a call and the other person hangs up it's fine. However if they do not answer and it goes to voicemail or I call my voicemail I get stuck in a never ending loop of press 2 to hear your messages.

Official windows phones have no hard end call button, just the on screen one, therefor I dont think its possible to end a call with the hardware button. Yes, the screen goes off when making a call, but due to the proximity censor it should come back when you move it away from your head. If it does not, make sure its not covered, even a screen protector can block the proximity sensor. Its located next to the speaker.
Hmm I removed the screen protector and still no joy when I move the phone away from my face. The screen just remains black. I did crack the screen about 5 months ago and had it replaced, perhaps they've done a poor job on this....
Don't think so... My is in perfect shape. proximity works on android but not on wp7... i also can't press end call button.
same thing with me
well i get the same problem with mine also, is there anything we can do for that.
I have the same issue, though it only happens to me when calling my voicemail. I hit "end call" and it just hangs there with the message "Ending call..." and I have to pull the battery :/ Regular phone calls have been just fine though.
Finally cracked this one!
I have been experiencing this issue on my Optimus 7 phone since day one, on all firmware versions and I now have the latest update.
This is what worked for me:
-set the automatic brightness to off and choose any manual setting that suits your needs, I chose medium.
-set the screen timeout to never (not sure that this is necessary, I will change it back to 30 sec to see if the issue returns and post back)
I hope this works with your phones, it was really frustrating to pull the batery out. Good luck!
I've had this issue as well. Pressing the end call button on the screen won't end many of my calls, voicemail or to another person. But it's rare enough that it hasn't bothered me, too much. But is a problem that needs to be figured out, if possible.
We should come up witha way to re map the hard buttons to usefull use

I'm assuming your phone is an HD2. First of all, the call should automatically end when the other party hangs up. Secondly, just hit the Power button to turn the screen back on and then unlock the phone and hang up. What is so difficult? WP7 remaps the HD2 buttons so they don't work as they did in WM.

[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???

[28 Aug] [Q] HD2 screen blnks out when talking...

Ok, I get that the screen is supposed to blank out when the receiver is held to ear. However, when I pull the receiver away, it is still blacked out. Should'nt the keypad turn on again? IE need to punch keypad buttons for voicemail etc. Is there some setting I'm missing here.
I'm running the latest TMOUS Energy Rom. Also have BsB tweaks installed as well. I looked over those settings again, can't seem to find anything affecting the screen blank out.
Also, the other problem I have. Using visual voicemail, when hold the phone to hear the message, my ear will cause the delete message screen to pop up.
Sometimes, also when talking on the phone, Ill get the screen you would get when pressing the windows start button. Very frustrating.
So, is there a setting I need, that turns my screen back on when I pull the phone away from my ear. Is there a way to lock the screen from any actions, when using visual voicemail, or talking on the phone?
I did a search of the forums. I couldn't locate anything related to my issues.
Any help appreciated.
Best,
David
try to press a hardware button to get the screen back on again.
I don't use voicemail so not sure how to solve it.
Hello Dr. I do punch the hardware button. I do get the screen back...however, when I do that; the screen wont blank out again, hence I end up opening other menus or programs.
Thanks for your input. After over 80 views, and 1 response; I don't hold too much optimism a solution will be available...but I'll keep checking, in case I do get lucky.
Its linked to the proximity sensor, you might try posting in the TMOUS Energy Rom thread as someone there may have a resolution for you
Proximity sensor always works back on my phone, but I have stock..
if you really need a custom ROM, try Dutty's for a change, it's really close to stock so it might do the trick for you.
