[Q] Calling Problems

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.

So we now have new causes for an old problem. Sorry I couldn't help.

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.

My screen sensor doesn't actually cover it, but I am easier able to live with it since I know what's happening.

Speaker phone help..

When I am on a call and I tilt my phone it goes to speaker phone and it is driving me crazy. I can not find a setting to turn it off. Can anyone direct me to the solution? I am sure it is easy and I am making this difficult.

Thats not a feature of the phone. When you tilt the phone your light sensor turns the screen on and your cheek presses the button

My face does not touch my screen. Why the hell does my phone go to speaker every single time I pull the phone away from my ear? The moment it tilts to the side the speaker phone turns on.
Edit: I finally figured it out. The app called Sanity is doing this. There was an option to disable the feature.

Proximity sensor delay after a call

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.

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

Phone wake when pulling away from face

Hey guys, here's my question.
My wife and I both have the s4. I'm on mf9 rooted, she's on stock unrooted mdl. My phone has always screen waked when I'm on a phone call and pull it away from my face during the call. My wife's does not. I have to manually wake it up once by pressing power. Then anytime after that during the same phone call it will auto wake like I want it to when I pull it away. After I hang up it starts the whole process all over again.
Any suggestions? It looks like all the settings are the same on both phones.

Do you have the "Turn off screen during calls" option checked? To get there, open the Phone app, go into the Keypad tab, click the menu button, and check to see if that option is checked. With it checked, the screen should turn on when you pull your face away from the phone during a phone call.

A screen protector can effect this if it is covering a sensor up above. But this feature can be turned on and off go into the Motion and Gestures under settings and make sure its on.

You might have a faulty proximity sensor on that phone. I had the same problem and it had to be sent to Samsung to be replaced/fixed.

but its most probably the screen protector and/or he doesn't have the option turned on
i am also mf9 rooted and it works fine for me

If the option is not turned on, then when he places the phone against his face. The screen would stay on. Right now his problem is the screen is turning off when it's placed on his ear, but will not turn back on when it's taken away unless he pushes the power to turn it back on. I had the same exact thing and it was a faulty proximity sensor that had to be replaced.

Disable automatic screen shutoff during phone calls

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
