I have a crack in my screen which seems to make the phone's sensor think it's constantly pressed against my ear, thus not allowing me to use the keypad during calls, switch apps during calls, and on incoming calls, not even hang up.
I was wondering if anyone knew of any way to disable the automatic screen shutoff so I can get around this. I am using CyanogenMod 10.2 on a rooted Sprint galaxy s4, but have had the same problem with the derrick Samsung os.
Thank you, and if I'm posting this in the wrong place, apologies and please let me know where it belongs!

The screen off during calls is controlled by 1 of the top sensors, not by screen touch...Maybe there is damage to or on the surface area above the sensor...

I know you're on CM but here's how it's done in stock, you can toggle the "Turn off screen during calls" when you bring up the dial pad and hit menu then call settings.
Unselecting that item keeps the screen on as it won't use the proximity settings (like when you put it to your ear) to turn off the screen...which is essentially what you've already described that you think is occurring with the crack in your screen...
hope that helps.

Never noticed that, thanks! I wasn't able to find something similar in my OS. I love CM, but I might have to switch back to stock for this.
Btw I also noticed it's accessible through settings > my device > call in stock.
Anyhow, instead of moving from CM, have you tried something like this app to turn off the sensor in calls https://play.google.com/store/apps/details?id=com.itsme4ucz.screenoff
or tried to use the Tasker app to toggle it off? might be worth a shot.
EDIT:
There was a mod for this, so you're likely to find something around that will coincide with what your running on yours - see this: http://www.modaco.com/topic/362514-mod-disable-proximity-sensor-cm101-based-roms-only/
also have you seen this thread on issues with this in CM http://forum.xda-developers.com/showthread.php?t=2409698 ?
AND the other option is to try blowing air in might help, just in case it isn't related to your screen crack....see also: http://forums.androidcentral.com/sa...edition/311795-s4-proximity-sensor-issue.html

I've started experiencing some problems when trying to make a call. Whenever I call someone, my phone turns off and locks, and I'm not able to turn the phone back on and the soft keys won't light up for 30 seconds or so. It's almost as if the phone turns completely off, but it's still making the call. This is only if I make a call. If someone calls me, the phone turns the screen off and on by itself no matter where I position the phone. It just flashes on and off.
I've been running jt's super clean v0.4 and the 11/02 kernel, and I had been running them for a few days before this started happening. I even flashed back to stock and nothing changed so I've flashed back to jt's rom and kernel.
Any help or suggestions or anything would be helpful. Thanks.
And I bet after a boot first couple of calls might be fine? Sounds like you may be using a task killer.
Put
com.samsung.phoneinfo and Call settings
in the ignore list.
good day.
Nope, uninstalled ATK and still the same problem. And the first call after a reboot still had the same problem.
Also, the only way it unlocks itself is if the other person hangs up.

Mine does that too.
It often blanks when I look at it, and stays on when I put the phone to my ear.
In my case the phone isn't actually turning off. It's as if the proximity sensor often doesn't work right.
The proximity sensor is that thing next to the speaker on top. It turns the display and touch screen off so that you don't press the buttons with your ear, and so that the phone doesn't feel too warm on your ear.
I highly suspect that the hardware is fine, but the phone isn't task switching fast enough when the hardware raises an interrupt.
This is the only time that lag bothers me.
This became less bothersome to me when I realised that the phone wasn't actually broken.
I also do not use task killers, because this ain't Windows.

Same here my proximity sensor just locks me out, i am trying to use the keypad and i have to unlock it over and over again. I restored my lock screen to original and it did not do it with a test call. But ill have to keep an eye on it. My biggest issue is the 3g connection dropping to 1x when i hit the web.
It was my screen protector. I guess it covered the sensor enough to block it. Hmm.
Sent from my SCH-I500 using XDA App
My screen sensor doesn't actually cover it, but I am easier able to live with it since I know what's happening.
Still tested different NAND-Android Roms on my HD2 but got still a problem. If i make a phone call and the screen turns black while calling i press the endkey to end the phone call. But instead of turning on the device, the screen stays black and i need to pull the battery and restart the phone.
If i make a phone call and use the free speaking funktion, while the screen don't turn off, i got no problem when ending the phone call.
I don't know what the problem could be, but it seems, that the thing has to do with the sensor who turns the screen on and off. But i don't know if this is the problem and/or know how to fix this problem. Like i said, i tested different Android Roms formated the SD-Card, deleted cache and all the stuff, but nothing fixed this problem. :-(
28 Views and no one with this problem? :-(
There are 2 other threads discussing this issue already. Here is one.
http://forum.xda-developers.com/showthread.php?t=946012
Issue lies with the light/proximity sensor. Could be defective hardware. Could be incorrect sensor drivers. Could be dirty sensors. I have yet to take mine apart to check for dirt on sensors. Blowing into the led/earpiece opening seemed to help. I notice if it doesn't come back on I can hold a very bright light (ex: cigarette lighter) about an inch away and the screen comes on as long as the lighter is lit. Sometimes it stays on.
thanks for your answer. seems to be more things to test and maybe solve this problem. Thanks!
THANK YOU Agoattamer!
Your link helped me to solve the problem! I just cutted a little piece of my screen protector, where the proximity sensor is, and got no more freezes after the phone calls! The screen protector still got two holes for the light and proximity sensor, but this seemed not to be big enough. Anyway, thank you a lot for your post!

I also tried a a lot of different NAND ROM and I had also this problem and I can't use Android efficiently. Now I am using hyperdroid ROM ( first GBX now CM). With this ROM and sanity app (from market, with correct settings you can find with trying) I almost solve this problem. ( probability of 95 % I don't get this error)
hey guys! i found the solution goin through the market!
download an app called "Sanity" theres a free version in the regular android market.
go to the settings > general > check "Reverse Proximity" (This will give you some warning about not using it if you DONT have a buggy proximity sensor). Check it anyways. Then go back to preferences then click "Proximity" scroll down and uncheck Turn off screen and leave leave the Turn on screen checked. this will force your phone to stay on during calls so that it never has to go through the proximity phase of calls this no more black screens. Hope this was helpful ^_^

Does any other one tried this solution ???
Hey guys,
is there any chance to stop the phone from switching off the screen on a phonecall?
My problem is that the phone does not respond afterwards and I cannot get the display to work (apart form connecting it to the power source). However, if I call my mailbox (or anything else where you need to touch-input during phonecalls) I am not able to use the display since it is turned off and there is no way to turn it back on.
So, is there a solution where there is a tiny program (or a setting-file, or kernel) that simply diables the screen-switch-off function? I would rather live with big ears typing the touchscreen whilst on the phone instead of rebooting after each call.
Thanks in advance,
jokeR.
There is a free app in the Android market called 'Call Light'. It's supposed to keep your screen on during calls, seems that it doesn't work for everybody though. But for me, it doesn't keep the screen on always during calls, but it does make the screen come on when i take the phone away from my ear. Before installing the app, i had the same problem as you, now i don't at all. If the app doesn't work for you, try changing kernels and still using the app. I am using Rapfringa's 1.7 OC kernel with the rom in my signature and very pleased with the results. Best of luck

i think its a problem with your rom.try new rom
to disable that option go to setting>call settings>tick off always use proximity

Hi guys just wondering if you noticed this strange behaviour.
I noticed a quite frustrating delay after a call when i take the phone away from my ear, it takes 2-3 sec for the screen to turn back on.
Has anybody experienced the same?
Do you know if there is a solution for this?
Sent from my GT-I9100 using XDA App
yes, think its normal. looks like the same delay when pushing power button for screen on.
sent from my SGSII via T*patalk
Thank you.
That seems strange as it is something really basic that you expect to work in a phone of this price range. Moreover it's something you come across quite often.
Do you know if the latest firmware improves this?

You can just turn off the sensor in the call app, if you want your screen to be available just after a call.. I don't see the problem.. but my delay is also just around a second or so.

But if I do that i will drain battery unnecessarily. I don't know you guys but I find it really annoying having to wait 2sec after a call for the screen to wake up. I want to be able to hang up immediately i think I'm not asking something ridiculous.

you can also set the power button to terminate the call and you will not have to wait for the screen to turn on...
Reading the data from an analogue sensor (such as the proximity one) is always tricky... You need time to level out the values coming back from it, then determine that, over a period of time, the distance is suitable to enable the screen.
Only then can it be turned on etc

How do you go about doing this? Can it be changed in the setting sor does it require a separate App?

Pls go to settings then call then calls answering ending and tick power key ends calls
Yes i find this very annoying too!
Especially when on a call center, press 2 (wait for screen) then press 4 (wait for screen) you get the idea
this is actually the only problem i have with the SGS2 since ke7

sgs 1 managed it fine though?....or am i missing something
Yeh my i8000 had no delay with the proximity censor.
But the screen delay seems to be everywhere. Turning on from sleep, time to adjust to ambient light and obviously the proximity sensor after pulling it away from your face.
Its not a major drama for me but I agree that it would be good to not have the delay.
I just noticed that when I use Skype the sensor works really well, meaning there is almost no lag.
I'm confused..
Sent from my GT-I9100 using XDA App
Yes! Very annoying.
Yep! I was commenting on this the other day. To be honest, I make and receive very few calls from my phone but when i do, I feel the rage rising inside me everytime because of the sensor delay.
It's the small things that annoy you the most.
As mentioned, you can opt to have the power button hang up the phone. It also does not turn the screen off, so you can continue working on the phone.
This is actually under accessibility settings, not call settings.
Menu -> Settings -> Accessibility -> Cancel the prompt -> Tick 'The power key ends calls'.
I also find the lag on waking up very annoying. Even once the screen has woken up, it takes a second for the touch input to be recognised so the pattern unlock only registers my last two or three inputs depending on how quickly I start swiping. I have to enter the pattern again. Very annoying.

I also have this problem, although I'd estimate it only takes about 1-1.5 seconds for the screen to come on.
I do however not think that this is a sensor problem, but rather a software problem.
Type *#0*# in the dialer, and press Sensor.
The phone will now vibrate once you trigger the proximity sensor. And it seems to be very fast and responsive here.
i have the problem using Skype...when i start a call it turns automatically the screen off ! i need then to push on home button to get out of skype...very ennoying...
last time i made an order online, my bank sent me a code by phone and following the instruction, the voice asked me to push the number i hear...i simply could not !! the screen was completely off ! and i could not succefully purchase online, my order was cancelled !.....due to this problem of screen..i think it is seriously ennoying and must be fixed in an update firm or something .
Agreed, this is a very annoying and unnecessary delay. Especially coming from an iPhone, where the screen turns on instantaneously when removed from the ear.
Hoping for a fix.
im ready to pay to get this fixed
trying to help a guy i work with, he has a verizon galaxy s5, i think he turned off the prox sensor because the screen now will not turn off when he takes a call and puts it up next to his ear, I looked though all the settings and didn;t see the option to turn it on or off in there like i have on my note 3. Does anyone have an idea where samsung hide that option in the settings, any help would be appreciated

I guess I thought this was normal behavior. This is news to me. Every other phone I've owned, when you put the phone up to your ear it turns off likely to conserve battery, and so the phone doesn't get too hot.
That is the normal behavior to turn off screen but I know there's a setting to make it so it'll stay on. At least there is on my note 3 and other phones I have had in the past. I just can't find it on his phone with the new layout of settings they did for the s5
