how to stop display turn off during telephone calls - Android Q&A, Help & Troubleshooting

We are developing hardware for Android mobile products.
We are using Samsung Galaxy mobile running on T-Mobile & AT&T cellular networks.
We notice during telephone calls, either dialing outgoing or incoming calls, the display turn off almost immediately when the telephone calls started.
Is there anyway to keep the display turn on all during the entire telephone calls?
I understand you can make all the hard buttons to wake up your phone by modify rhis register,
HKCU\Control Panel\Keybd\
and create REG_DWORD "DefaultKeyLock" Value "0"
Please tell me step by step instruction on how to modify this register inside Android?
thank you

Phone turns off due to proximity sensor...best would be an app to toggle proximity sensor...use that and phone wont go black
Using XDA premium through A5
Press thanks on help

use some proximity toggling app that would seal the deal...

Our why not just on brightness change it to "always on" our never sleep or something like that :c

to set display at the highest brightness and have the display always turn on will likely cause high battery consumption.
That must be better way to keep display on during call to watch the minutes duration of the call.

Just pull out the proximity sensor!

This kind of thing happens on my wife's phone. She has a Samsung galaxy s iii. When she tried to check her voicemail the screen shuts off as soon as the call starts and she always has to press the power button to turn it back on to type in her password. Thought it was just her phone being weird, but maybe I will have to check to see if her proximity sensor isn't working correctly.

Ringer delay for Sprint?

i saw a post about ringer delay for AT&T user and they just need to disable the dialer and the problem solve but what about us sprint users? Here is the original post about that http://forum.xda-developers.com/showthread.php?t=449417
i tried to disable the dialer on registry but still get 2-3 second delay before my Touch Pro actually ring.
Download and install DiamondTweaks. There is an option to disable the ringer delay. Works well.
convert your ringer to .wav file

The ringer delay that this changes is the pause between when the ringtone ends and it repeats. Not the delay from when the LED starts flashing (because a call arrived) till the phone actually starts ringing.
If you wish to turn off the HTC dialer and use the WM Dialer, simply goto the following registry entry,
[HKEY_LOCAL_MACHINE/Security/Phone/Skin]
"Enabled" = dword:1​change the Enabled value from 1 to 0 which will disable the HTC dialer.
I vote for converting to WAV files as well.
If you would like to complain to Sprint about it, the following is the thread I started on Sprint's forum regarding this very subject.

Depends on what you may have done (adding programs, etc..) to your phone. By default, our devices will turn the screen off to conserve battery while a call is in session. However, if you have added one of the S2A dialer GSM versions which was taken from the Touch HD, that feature was disabled because of the InCall curtain. The CDMA versions (my signature and others) were taken from the Sprint Diamond ROM that was released and still contains the necessary code to turn off the screen display while the call is in progress.
Smotrs...just HR'd and installing now. I haven't tried that one, and actually think I ended up with the GSM version I WAS using.
I'll let you know how it works.
Thanks...
Well, it still sits there while the screen "times" out. I thought the light sensor was supposed to dim the screen almost immediately. I'm on the call for 30-40 seconds before it dims, and then cuts off.
Is this a Sprint thing?

It should Dim after about 10 seconds (or whatever you have in the backlight Advanced setting under Battery). After about 40 seconds or so (same location) it should turn off the screen.
At least that's what mine does, just verified it again. Sounds like maybe your values are too high. After a HR they usually are by default.
Somehow it was at 30 (dim) and 1 min (off). That is a little high. Changed it to 10 / 40. We'll see what that does.
Thanks for the tip. I'll keep you posted.
Seems to now be working the way you explained!!! Thank you for the help!
Is there anything else out there, other than S2U2 that allow FULL SCREEN Caller ID pictures??? I don't want to reinstall that because the dialer is actually working right. I just miss full screen caller ID.
Thanks again.
That I don't know, sorry.
Eh...it's ok. I'd much rather have a dialer that works than a full screen picture of my ignorant brother.
you can also change the Slot Cycle Index in the epst settings... you'll need your MSL though
it's under "Modem Settings"
What is slot cycle and where are these settings? How do I find my MSL? I don't see "Modem Settings".

Changed the SCI to 1. We'll see if that helps. There is always "0"!
I'm also seeing mixed reports/opinions on ACCOLC - Access Overload Class. Mine was defaulted at 8 on Sprint. People say leave it alone. People say set it lower. Others say set it higher.
i found that setting SCI to 1 is good enough, i'm able to catch my calls and haven't noticed decreased battery life from it so that's where mine stays.

[Q] AT&T SGSII - Turn Over Silence Feature?

Hey everybody!
I just joined so this is my first post and I am a iPhone 3GS convert. I am finding that the turn over silence feature only works if the phone already starts ringing. It does not silence future calls/notifications. This seems totally useless as it can also be silenced by pressing one of the volume buttons.
I would like to silence all calls and notifications by turning the phone face down and have it revert to normal mode when turning it over or picking it up, etc...
Is this possible? This feature is weak and useless and I cannot believe this is how it was implemented. Is my phone defective?
Thanks in advance!
This feature works when a incoming call is coming
when phone is on a flat surface with this motion effect activated,you will not get anysound or vibrations or you will get sound or vibration for just one second or even less
there is bug in this feature to be sorted out i think
Thanks for your response!
For me it doesn't silence anything. The phone rings and notifies as if it was in normal mode. There is no change in the behavior and I am positive the feature is enabled in the settings > motion menu. If it is a bug I hope they fix it because this a useful feature for me.
Are there any apps that might provide this functionality?

Welcome to XDA!
Thank you. I have submitted a request to have it moved.
Bump........
I'm afraid to say it but what you're asking for is not the intention of the feature as it is. They designed the motion control in this scenario for you to quickly grab your phone and turn it up side down to silence the ring without having to press a button, etc. I agree that's it's not all that great but I can see the benefit for some people.
Your phone is not defective, it just doesn't work the way you thought it would.
And just to add a little logic to the scenario... the feature is called 'motion' so it only works when motion occurs. If the phone is resting upside down, that's not the same thing.
It's called Motion Activation. You hear a phone call comes in, flip it over, the ring silenced. If you keep the phone upside down, there is no motion to activate anything and it won't silence anything. It only works for incoming calls and you need to flip the phone at the right time. Useless feature, as are all other Motion Activation features listed there.
Brilliant! So does this include notifications from text messages too? They must last at least a second or two. If I react quickly I could possibly silence around half of the notification! Useless! If this is truly the intended functionality then that is rediculous to me. Not to mention useless.
The point is putting the phone into a mode that emits no noise; not reacting to a noise that anyone that can fog a mirror can hear and then "flipping my phone over to silence it." If I flip the phone over then I don't want it to make noise. If the phone doesn't have that feature then fine. I find it a useful feature that is missing or poorly described/implemented at best.
"Logic to the situation?" Please. There is no logic in implementing a turn over silence feature the way you have described.

LoL. If you read the other Motion features Samsung implemented here, one of them is zoom in and out. The procedure is quite laughable and in the end, it is ten times easier to just pinch zoom on the screen. I don't know why Samsung even waste time on this.
Try these apps
Have you tried Flip4Silence or Flip-Silent? Both are free apps and seem to have decent reviews.
Thanks! I will definitely give those apps a try. I appreciate the response.

Hi guys,
After many hours of searching around the web i found a solution for this problem.
You just need to calibrate you phone, to do this follow the procedure:
1) Place your phone on the flat surface
2) Go to Settings > Display > Horizontal Calibration > and hit Calibrate
3) Go to Settings > Display > Gyro sensor calibration > and hit Calibrate
Now try the turn over feature
1) Go to settings > Motion > enable Turn Over
under tutorial > Turn over > Try > OK > once it starts ringing flip your phone
This should work fine!!
Cheers!!

I've used it since froyo and its really easy to set it up to silence phone on face down.
I must be dense. If you want the phone to be quiet when sitting why not just put it into Silent mode?

I agree.
The feature is not there for a long term "silent mode", it is there to quickly silence the phone if it rings during a conversation, conference call, meeting, etc. I can it being useful for many people.

Wake screen WITHOUT mechnical button (PWR/Volume)

I would like to wake from screen timeout without using any type of mechanical button (Power or Volume Buttons). I was ideally hoping the proximity sensor with the proper app would work but all the apps I have tried (MANY) have not worked properly on the Atrix 4G (cover proximity sensor screen OFF else ON, maybe with delay option before turning OFF) I would be happy If I could touch anywhere on the screen to wake the screen. My Atrix 4G is running factory 2.3.4 and is rooted and my wife's Atrix 4G phone is running 2.3.6 and has not yet been rooted. Seems like a rock solid working app to perform this functionality should be available for the Atrix 4G/MB860 smartphones?
Any help on this issue would be greatly appreciated!!!!!
Don't want to wear out the fingerprint/power button!!!
Regards, Ron
PS-- I would gladly pay a nominal price for a working app (better than wearing out the mechnical switches)
that is not posible
Sent from my MB860 using xda app-developers app
It is possible, but it means it would have to keep the phone in a state of semi-awakedness at all times, never letting it go into deep sleep, thus draining the battery pretty quickly. Also monitoring the sensor constantly, thus draining even more battery. It also means the sensor would emit the faint red light all the time, which many find annoying.
Battery drain will be your best friend.

Proximity Screen Off:
http://forum.xda-developers.com/showthread.php?t=876945
Thanks for the replies!!
I am aware the phone could NOT be in "deep sleep power save mode" and work without using either the power or possibly the volume button. A couple of Google Play "Pay Only" apps indicate they can be configured to wake the display using the side volume button (this would at least preclude the use of the power button to wake the display). I assume the volume button would still adjust the audio level? If anyone can comment on how well these apps work on the Atrix 4g, that would save me from purchasing an app that doesn't work as desired. From my understanding, the display uses the lions share of the battery bugdet. There are also apps that claim the display can be turned on by shaking/flipping or using the proximity/light sensors (anyone get any of these apps to work on the Atrix 4G?). The phones battery life should be extended by simply turning off the display. Waking the phone by something other that the power button would just be ONE of my usage models. If I want to get the maximum battery life, I would wake the phone using the power switch and not use any after market apps.
Thanks Again Very Much for your forum posts and any further help would be greatly appreciated.

widgetlocker lets you wake the phone by volume buttons, by disabling the stock lockscreen and replacing its own locker. it doesnt effect the sleep mode but disabling lockscreen may cause problems like unwanted call accepting. widgetlocker can put its locker over the callscreen but it still wont display the calling number. you may first try the app and then decide to buy it

Possibility to wakeup with a shake is solely depends on the kernel implementation.

Sent from my D6503 using XDA Premium 4 mobile app
I never mentioned vibrations!!!
I should have explained it a little better though
when you make or receive a call and you are on the phone the screen turns off and disables all button presses because the proximity sensor is covered
but even though the display is off and the sensor is covered you can still press buttons whilst on the phone
so far I have tried sending a text
cut people off
muted the phone
put the phone in to airplane mode
added events to my calendar
and more
all this with the side of my face while in a call

[MOD][XPOSED] Call Screen Sleep Fix

Experimental Module
This Xposed Module will prevent Phone Screen to sleep(lock) during phone call.
Proximity sensor will work as it is i.e. Display will go off when proximity sensor is covered but screen won't sleep
Especially useful when loudspeaker is on and "Power key ends call" Accessibility feature is turned on.
display wont go off thus accidental call termination can be avoided.
Note: First Xposed Module
to test this module set sleep time(in phone Settings -> Display) to 15 seconds or so and place a call, if screen doesn't sleep after defined seconds it worked
Download at Xposed Module Repository. repo.xposed.info / module / pkg.x7491.xposed.callscreenfix
Tested on various devices. if it does/doesn't work for you post your ROM and Device Details

This module prevent normally your screen goes to sleep when you make a call with speaker. But with this module my screen goes off anyway when I make a call. And yes with pressing the powerkey you can turn on the screen again. That also worked on Android 4.3.
