Black screen after phone call - Samsung Galaxy S7 Edge Questions and Answers

I had the phone for 3 months. Last week, every time I make a phone call, the screen turns black and I need to wait 2 or 3 minutes to be able to use it again. Is anyone having the same problem ? I'm sure that the sensors on the phone are working btw.

To test that your sensors are working, dial *#0*# in your phones dial pad.

1.61 is the proximity sensor bug fixed?

Hi,
Had the Leo since launch and it's driving me crazy with it's bugs.
Does anyone know if the following bugs have been fixed in 1.61?
1- Proximity Sensor intermittently not working correctly- I was on a call today and I cut the caller off 3 times.
2- SMS getting stuck in the Outbox.
I've already upgraded once to 1.48 I don't want to upgrade again until I know it's fixed.
I should learn in the future not to buy Version 1 of a product. The leo (HTC HD2) feels more like beta (field trial) 0.8 software.

Well, agree to some extent on the "field trial" feeling...
However, I never had the proximity sensor problem, and since I installed 1.61, the SMS issue did not come back (had it rarely before, though).
Personally, the much better radio which comes with this update is worth the flashing alone... but that´s my personal opinion...
Have you got a screen protector on the leo?
when I use mine, the proximity doesnt work fine and I neet to cut the plastic of the protector of that zone
The proximity sensor also doesn't work with hair. Do you have long hair that covers your ears?
I noticed this when my girlfriend used my phone, the screen just wouldn't go off.
I use 1.48 rom and very strangely i have proximty sensor problems when calling numbers that are not on my carrier network ... don.t whant to report it as a bug but ... strange. Even so, have you tried to disable phone canvas cover? Seems it doesn.t switch on so often when this is disabled (using BSB Tweaks)
well my experience with proximity sensor:
when i just make a call it works fine.
when i use the keypad after making a call (for entering extensions and stuff) the proximity sensor stops working. it happens every single time I use the keypad while in a call. I will soon report this bug to HTC.
I don't have any screen protectors on.

just been testing that, I can't replicate it at all.
start a call, press keypad, enter some digits close keypad, or don't close keypad, proximity sensor works fine.
on 161
I have some strange bug with calling screen.
When I call to somebody and talk more then 5-10 min, then I can't press Disconnect red button.
But sometimes, if I call and don't hold phone near of head, for headset for example, I haven't any problem with screen, all buttons pressed normally.
Very strange behavior.

Had exactly the same issue with 1.43, didn't notice it *yet* on 1.48. Screen wouldn't dim after entering dtmf.

Interestingly it's my wife who uses the phone and she has long hair- that fits in with the previous posting
Why does the proximity sensor not work with long hair!!! She still has the phone close to her ear. I can watch her during a call and the screen lights up and activates on and off. I'm not too sure if there are two bugs here- one is radio cutoff, and the other a proximity sensor issue.
I called her a few times over the last day- and cut offs are quite regular.
Previously I used to get various DTMF digits sent down the line as well from her cheek touching the screen, but not now.
I'll give this phone a few more weeks before it get sent back.
FYI- I do not use a screen protector.
With regards to the proximity sensor... I'm on the LEO with a WWE 1.48 rom (experienced the same thing with the original 1.43). Like you all say, it is still a bit flaky at best, though did improve with 1.48. However I find myself doing a little work around...
(to note: I do have the official screen protector attached on as well - it has 2 little holes for the sensors in the film)
• Make or receive a call
• Drop the “virtual” guard
• Enable loud speaker mode / Disable loud speaker mode
• Talk/Listen to your call
Hey presto... you should find the proximity sensor working again. (Got it down to a fine art... the other end doesn’t even realise)

Me too ! Im on 1.43 WWE ROM
i upgraded 1.61 and noticed the proximity bug once yesterday
the only time it happend was when I was ON a call and had another one coming in (call waiting) ... so once i switched over to the other caller, my proximity sensor stopped working
No idea why...but i tried it again 10 minutes later and it worked.
So its intermittent...pretty annoying though
I hope HTC is aware of the problem
I think not... Its getting really annoying

Do you thing the original screen protector from HTC make all the problems with the proxi,ity sensor?
I have the same problem with this sensor, I am not sure which hole the is proximity semsor?
thake the screen protector out or cut it and the proximity sensor will work perfect

[Q] Turn on & off Screen during call?

Hi there!
Sure it's easy to fix this problem of mine but I just did not find the way.
If I make a call, the screen automatically turns off, that's fine. However, when I call somewhere where I need to dial a few numbers, I tap a button to turn on screen again, however, I haven't been able to find a way to turn it off again.
Yesterday during a call to my ISP where I needed to press 1-3-4, I accidentally hang up the phone call 3 consecutive times with my cheek, just because the screen was not turned off.
Thank you in advance.
Cheers!
I believe it has a proximity sensor, so the screen turns off when its close to sommit. The sensors are top left of the phone. Just try it, and see if it always stays on when you put your hand close to it.
Hi MalekoUK.
Thanks for your answer. I already tried this and it did not work, this is why my call got hung for 3 consecutive times...
Is there a Default switch or parameter in the registry to test if this sensor is activated? Another way to test if it works properly?
Cheers!
Well there is a tweak for the proximity sensor in development now, take a look and see if it helps or fixes it:
http://forum.xda-developers.com/showthread.php?t=624206
Maybe you have a faulty prox sensor? Also, maybe a hard reset will fix it?
It's strange, sometimes it works, sometimes it doesn't.
My ROM is an Official 1.48 ESN
No one else has had this issue?
Cheers,
Well, I'm somehow glad to see I'm not the only one... See Here

Proximity Sensor Doesn't Work!!!

Hi guys,
I got my xperia x10 and the proximity sensor doesn't work. Even in test mode it just says off with a dial tone. Any idea what I can do? Ive tried flashing firmwares.
Regards
corruptfate
The proximity sensor in X10 does disable the touch on your screen immediately after you put the phone to your face, and it waits about 6 or 7 seconds to turn off the display.
you can test it, call someone and put your finger on the top of the screen( beside the earpiece ) and try to cancel the call.
ya but the thing is it doesn't work in the service menu...
I tested it now and it's working fine from the service test menu. it even detects my finger about centimeter and a half away from it.(give you a tone and write "ON" on the screen)
When you test it in the service menu... are you actually covering the proximity sensor? it won't activate unless you cover it..
it's just above and to the right of the word "Ericsson" at the top of the phone.
yes it is the little black thing It works on my brothers but not mine when I open the test i just hear a dial tone and see off even when I try to cover it
Sounds like you need to take it back then.. either get it repaired or replaced..
but it's working while you are in a call, so don't bother yourself.
maybe it's just a software error.
thats what I'm planing to do... thanks for your help guys

Screen stays off throughout the call.

Hey friends,
I am facing this problem while making calls that as soon as I press call button or receive button(while taking call) the screen turns off n stay that way till the call ends.
I have tried pressing all hardware buttons,even moved the dvp awayfrom me n into direct light but to no avial.though it did turn on once or twice out of twenty times.
Did anyone else experience this? Any suggestions are welcome..
Sent from my HD7 T9292 using Board Express
Do you have a screen protector or case that is obscuring the light sensor or proximity sensor? My first guess is that something is obscuring one or both, because during a call the screen being off is a feature.

screen stays black/off during call
The screen stays black during a call and this happens ramdomly. I have a dell venue pro a t mobile phone but it is a pre release so it works on att 3g and all. I have switched the sd card with no improvement. I have ordered a transender 32 gb sd that I haven't received yet. The firmware version 2250.1400.7004.025 hardware is 112.576.2.0 radio soft 2.2.50.14 radio hard 8250. I have been unable to get any of the hardware keys to hang up the phone which if I get voicemail or something means I have to power the phone down to get the dang thing to hang up. Sometimes it works fine but I cant find a commonality software or hardware that causes this. It happens right out of the box so even after a software reset it can happen. Is there any solution for this issue?
I can't understand why the button on top doesn't hang it up.
PS I got this phone for free and I got ripped off LOL
wow just got a replacement phone today and im having this problem, As soon as I go to make a call the screen goes black and cant do anything on screen during the call, so i cant enter my password when checking voicemail
I think it's related to the proximity sensor. When you put the phone close to your head, the screen switches off. When you move it away, it will switch on - most of the time .
If it stays black, have you tried tapping the power button on the top of the phone? It switches the screen on without disconnecting your call.
A coworker got a replacement the other day(they send a refurb) phone and it had the same problem. Had to go through Twitter to get Dell to send him a new retail phone since they had send him 3 refurbs prior and they all had different issues.
This is just a general statement regarding phone proximity sensors. I have had multiple phones made by different manufactures that experience this to some degree (including the Venue Pro). One thing that I have noticed is that if the phone goes from your face directly into a bright light (outside is most common) it will keep the screen shut off but if the sensor is somewhat shaded it will resume normal function.
I got the same problem too and while it may be a proximity sensor problem, it is not controllable on the user's end. Unless the phone call disconnects magically, a battery pull is necessary.
I'm gonna be on my third one soon and I hope that i won't face the same problem.

Yes i recently got a new refurbed phone and this problem has arised. Complained to Dell and they are going to send me a Brand new DVP. I see a lot of people having this same issue with the refurbs. Currently Dell is out of new DVP due to them upgraing the firmware, so I have to deal with a broke phone till the end of August. Talk about a dissatisfied customer. Im thinking about selling this brand new unit when I get it, hopefully Toshiba has their device out by then
This is a Proximity Sensor issue. You can fix it though in the EM app. You can adjust the sensor readings and the phone will function like normal. Let me know if you need the values or a step by step!

A step by step would be awesome. I like being able to see the screen during a call.
1) Get the EM app, if you dont have it dial ##634# into the dialer
2) Get into the advanced menu by double tapping the black area and typing in "qwertyuiop"
3) Select "RD test", now enter *#6336# in the box that pops up.
4) Select "Sensors", and the "Proximity Sensor Config"
5) Set the following to these:
LED strength - 1
Diode select - 2
Pulse Count - 43
6) Hit set and then you are good to go!
I have noticed that one of my DVP's needs to have this put in again everytime I reboot the phone, the other saves it. Just an FYI for ya!
I get to step 3 and when i clock on RD test, I am prompted with a white box with blue trim and an X at the top right. can you advise on how to proceed?
Oh yeah, Im sorry I forgot that part. Enter *#6336# as the password.
When I dial *#634# it says thic code is not supported.
What does that mean?
I put in a different number combo before and it put me in the EM screen

Proximity Sensor help needed!

Hi all,
I think my Proximity sensor is broken..... can one try the following:
*#0588# (Proximity Sensor Test Mode)
And tell me what happens when the sensor is covered?
Also anyone got suggestions on how I can fix this?
Thanks
Tony
It works for me with *#0*# then select sensors and then move your hand close to the phone.
It also works with your code, the phone vibrates and the background changes colour when my hand is 5cm above the sensor.

Can you please tell me what it says in Sensor?
In Proximity Sensor I have:
Proximity Sensor (Min/Avg/Max)
------------------------------------------
PROXIMITY: null ADC: 0 (0,0,1)
and sometimes when I cover the sensor it changes to : ADC: 2 (0, 1, 2)
Thanks
Looks like it is broken ACC 78(83,85,89) with my thumb over the sensor.
The important number is the first number (78). This must go over 10 to register as near at about 5cms , then the background turns green.

Thanks for that. Do you know if it's a firmware (I do have original Firmware on it but had CM7 on it for a while)
Looking like a faulty phone to me. These are hardware sensor tests.
a friend of mine has the same problem. We bought the telephone together but , after 1 month, his proximity sensor stopped working.
We tried the samsung diagnostic tool receiving the same information (ADC reach maximum 4).
we noticed that it stopped working after the change of the rom (with the installation of the clock recover) but I'm sure this is the real cause.
Is there a configuration file where proximity sensor parameter like gain/offset are stored?
Maybe some buggy application has changed these values.
if you have no warrenty, you can buy a replacement sensor, only about £10, it's front cam/sensors in one component
problem fixed!
Using phonetester it took 5 minutes to connect to the sensor (while with my phone it took 1 minute) but once connected , the proximity sensor started to work again also with samsung diagnostic and phone application.
