[Q] Screen blanks when Making/Receiving Calls HELP! - General Questions and Answers

I have tried searching for some time and have encountered several different opinions on how to resolve the issue however, none so far work.
When taking a call or when placing a call after connecting to the call the screen goes blank in what seems to be 2 seconds even though I still have the unit in my hand and not up to my face and I am not touching/blocking the proximity sensors.
What is the definitive answer on what I can do to make a change to the settings to prevent the keypad/screen from blanking out while in a call?
I have the display settings set to keep the screen on when not in a call to 10 minutes and always on when connected to a power source. For the life of me I cannot find a resolution to this problem.

have you got a proximiti sensor? Meaby you screen film blocked it

I think your proximity sensor is broken.. try to search in play store for "proximity sensor" i've heard of an app that can turn off your proximity sensor when calling but i don't know for rooted devices or non rooted
Sent from my GT-I9000 using xda premium

Nope, I do have a screen film installed however, it clears and does not block the 2 proximity sensors on the top front of the phone.
I installed a Proximity Sensor APP from the market and it registers the device as working and activates the sensor at about 2 inches away.
I did notice today that when using the phone to call T-Mobile voice mail the dial pad does NOT blank during the call.
Does Android have a config file anywhere for this or is the screen blank setting built in to the system or perhaps the dialing app itself?

Touch In Call Screen not working on the HD2

I tried to install this great piece of soft, Touch In Call Screen Tweak, because I am not totally satisfied with the way the HD2 manages the backlight during a phone call.
http://forum.xda-developers.com/showthread.php?t=488991
Sadly, for some reasons it seems that Touch In Call Screen Tweak does not work on the HD2.
Did someone try? Any idea to make it work?
thanks...
Sorry but in what way are you not happy with the way the HD2 handles the screen during a call?
Surely what Touch In Call Screen Tweak tries to emulate using the G-Sensor etc. the proximity sensor does effortlessly on the HD2. I really don't see what you would want to install Touch In Call Screen Tweak. Unless I am missing something?

Richard,
Because I think that Touch In Call screen is far more efficient:
- The HD2 only uses the proximity sensor, whatever the position of the device,
- Touch In Call Screen combines the proximity sensor AND the G-sensor.
I am using my HD2 a lot, and sometimes during the phone call I touch the screen and enter in the Menu by mistake. The HD2 system does not work all the time.

I have not experienced any issues yet with the proximity sensor and knocking menu buttons.
I also didn't realise the software could use the proximity sensor as I thought it was designed around devices like the Diamond & HD which don't have proximity sensors.
I find that If the phone is away from my ear then I would ussually want the screen on. Not sure how it handles the screen when using speaker phone though.
Touch Incall screen tweak doesn't use proximity sensor, it uses the g-sensor and the light sensor to emulate what a real proximity sensor does.
I haven't used it on HD2 but previously I've found it difficult to set up because of confusing wording in program settings. So I wouldyousuggest that you try to fiddle with them a little more.
On a side note, while TICST is just an attempt to emulate the real sensor in HD2, it has an option to keep screen off while using headset, which is something I'm badly missing now...
Hi, anybody knows how to change the settings of incall screen off on HD2? My HD2 don´t dim the screen while i cover the proximity sensor during a call.
Is there any menu or registry setting?
Touch screen stays on during call (phone by ear)
I have the same problem: my touch screen stays on during a call when I have the phone by my ear. I have this since I upgraded to the official HTC 1.66 rom. Anyone experiencing this as well? Any solutions? Help would be appreciated...
Hi. Same here. My screen stays on as well. Did someone got a solution?

nosh10, that's interesting. Which cooked ROM did you flash, and did it solve the problem of the screen in call? Besides that, does the ROM work well, or does it cause other problems?
I have the same problem as everybody else here, using stock ROM 1.66. Screen doesn't turn off reliably in call (sometimes yes, other no), leading to push buttons, hang up call, accidental conference call with Australia, China, and US .

Proximity sensor issues?

I'm running CM 7.0.3, and I'm having massive proximity sensor issues, t the point where the phone is becoming unusable. If I'm in a call and I don't manually shut the screen off, the following happens (constantly):
I'll feel some haptic feedback on my ear, and my voice will mute. When I look at the screen, the lock screen is up and when I unlock it, it's at the dialer screen. I'm not hitting the mute or hold button with my ear, it seems like once it gets away from the call screen, my voice is muted.
Needless to say, this is getting massively annoying. Later tonight I'm going to try to see if using a Sense based rom fixes this, but I'd much rather stick with CM. Has anyone else experienced this?
I believe there is another post on this.. you can also Google search for inspire proximity sensor adjustment - someone created an app to adjust the sensor

The thread in question:
http://forum.xda-developers.com/showthread.php?t=1062561
EDIT: I haven't used the proximity sensor adjustment application that's linked in the thread as mine is working normally. If it doesn't work there's a possibility the sensor's faulty and should be replaced (I recently went through this whole thing with my old iphone 4).
Yeah, to be honest, I tried that app and it didn't seem to make much difference. I'll try calling HTC
Flashed to a sense based ROM, and the sensor seems to be working fine. Very odd, to be honest. I will say that after using AOSP for so long, I have no idea how you guys deal with Sense at all.
Well, now I have to decide: I can live with Sense, or I can ship my phone back to HTC and be without a device for 2 weeks. Going to try out the proximity sensor app again, but it didn't seem like any setting made a difference, but it could be that I just don't know what I'm doing with it.
Check under Settings>Call Settings and put a check mark in the "Always use proximity" box. It says it's to help with prox. sensor screen locking when the phone is horizontal, but the CM7-based ROM that I was using showed the same issues and I fixed my particular issue by checking that box.
Tested with a few calls and the screen is definitely shutting off when the phone is standing or lying down.
I read up on the proximity app, and I think I have it calibrated properly at 5/6. It certainly helps, but it's definitely not perfect. Night, thanks for the advice, but yeah, that option has been checked from the start. At least the issue is tolerable now, before it would do this 10 times per call.
Funny - mine was calibrated at 10/11 by default and works pretty well. Try going up to those values. I used a local time/temperature number here, and it worked well when my finger got 1/8" or so from the phone. While I admittedly haven't measured the depth of my ear or anything, it does seem to be working well at those settings.
I think the upper threshold is where you may want to adjust. From my playing with that app, changing the lower threshold too high will make it ignore things too close to the phone and so will an upper threshold that is too low. Try lower 5, upper 11 and see what happens. Anything between lower and upper apparently triggers the sensor. (<<< speculation without documentation)

Dim red light next to proximity sensor

Hi,
I just saw today, that there was a very weak red light just next to the proximity and light sensor. It looked like it was flickering at a very high rate!
I tried to restart the phone normally, but the light didn't disappear. After that I tried a reset by holding the power button down for 10 seconds. That made it vanish.
What the f**k was that all about???
Best regards
Casper
If you were making a phone call, the red flashing light is normal It's the proximity sensor. If you were doing nothing, it should not be seen the red light, might be faulty.

Its The Goverment Spyin On us...Making Sure We Dont Flash Anything Or Even Root...If So It Will Say Tampered And The S.W.A.T. Team Will Come Crashin in Our Homes...
That red light is in fact the actual proximity sensor and it's in use while in a call. If you where not in a call then that was a strange occurance unless you ran some of these sensor testing apps...
Well, I wasn't in a call. I had been calling someone through the hands-free in my car on my way to work, where I discovered it about 10-15 minutes after the call was finished...

That was an odd one... maybe it was a temporary fluke? Strnag nonetheless...
I often use face unlock. The red light turns on when the front cam turns on.

any tips on how to trouble shoot this? I wish I could figure out which app (if any) is causing the proximity sensor to stay lit.
I've heard it's related to an autobrightness tweak, but it appears even when tweak is not applied, across multiple roms. The only commonality between my roms is the apps I have installed.
I've tried multiple proximity sensor testing apps and, it's working.. it's just always lit up.

Same here. Have to restart to get it off again. Any help? (TrickDroid 4.3)
Anytime you make a call by any means other than handset to your ear, the proximity sensor will come on and stay lit until reboot or until you make another call via handset.
Example:
Place call> turn on speaker phone> hang up - proximity sensor will stay lit after call;
To fix do this:
Place call from handset (not using speaker phone or hands free) and hang up right away, or reboot device and light will go out.
Same seems to go for calls through hands free as well.
These guys are lying its a bomb isn't it obvious flashing red light HTC controls it if u do something they don't want u to do boom ur hands are no more why do u think the phone heats up so much its a warning don't believe me read the thread in forums about heats in the one s another reason they don't want us to remove back well see the bomb :what:

Hi All,
My One S also does this. I'm finding it a pain to have to make a call after using speakerphone to turn the proximity sensor off again. Has anyone found out what the cause of this is?
I've tried clearing cache partition with HTC support but still no fix.
Hi all, I forgot to mention that the issue on my phone only happens when the call is ended with speakerphone active. If I turn off the speakerphone before ending the call it does not happen.
Hey brothers.. I had the same problem with the proximity sensor not turning off.. Even after so many restarts resets... Finally I just opened the original task manager of the one x, and push "stop all" .. and YES!! the sensor was turned of and stopped lighting.. After that I tried calls with speaker phone or not..

You maybe have turned off Viber doing this: http://www.boards.ie/vbulletin/showthread.php?p=80972874
Does it come back after restarting Viber?
Sometimes a restart fixes the problem.
I had the same problem. I uninstaled Viber and the light disipired.

[Xperia Miro] Problems with the Proximity Sensor

Hello there.
I have recently had to replace my screen on my miro due to a crack, This went successfully in the fact the phone now works as before, with one minor problem. Since trying to make and receive calls my phone automatically goes to a black screen. this after many searches on the net resulted me to conclude that the sensor is blocked, as the screen digitizer was slightly different for the top left of screen too. the place where the sensors live. In can go round the problem with a set of earphones but sometime a call will cut off more using them. I downloaded the hardware disabler developed on this site but it doesn't load any drivers and then crashed, there also appears to be no other hardware disablers out there, or at least none I can find.
Basically I need some help on restoring the call function, either by fixing the proximity sensor or by getting rid of it
Any help will be welcome on this matter.
thanks

ghost/phantom touch issue in 1+7pro not solved

I have reading the forum and tried contacting 1+7 also but they just say switch off nfc and so on but till today (1 month since I bought it ) I still have the problem . while making a call it goes on hold or connects another call or something or the other happens and the other person gets irritated as if I am doing on purpose. I am still unable to solve this will changing rom be the solution or can someone please help I am fed up with this instrument
My 2 cents... are you sure that it's a ghost touch issue? To me it seems more a proximity sensor trouble... it is possible that, while in call, screen doesn't go off (or wake up while you're talking) and your ear triggers commands at random.
Try to check that your screen remains black while in call, else you could try to reset sensors with one of the apps available on Play Store.
BTW: I had a similar problem one or two times, but maybe because I wasn't so near the phone while I was talking.
will try out can you advice reset sensors apps

Search for "Proximity sensor reset" or similar names. Usually apps like that needs root privileges, btw.
I've had problems with the screen waking up and then causing problems while in call too. This while it's still against my face. Apparently touching my face makes it go into other apps and causes problems. I've had it go into airplane mode, mute and do other weird stuff.
I've had the screen go crazy with multiple chains of taps too, especially while holding it in landscape mode.
Turning the refresh rate down to 60 Hz helped some, but the problem's still there.
I think there's something jacked in their implementation. I came from an S8 that had a curved screen and I never had the phantom tap problems I have with this thing.

I'll try that, but I don't think I have that enabled. I disabled NFC for the other tap issues and that helped some.
I really wish there was a screen calibration tool. Samsung curved screens have none of these issues.
Do you have a dirty screen protector?
This is a known bug with the proximity sensor, although, actually, I believe the root cause is something else.
Screen does go black, which indicates the proximity sensor is working and recognizes your face is near... But input is still allowed (meaning it does not lock it).
As a result, during a call your face/ear will press whatever is underneath and trigger random actions.
I believe (I hope?) that OnePlus is aware of this issue and they issue a fix.
I think it was briefly fixed for 9.5.9 and then reverted on 9.5.10 since it introduced other issues.
Quality control has been a bit subpar on the OnePlus 7 Pro builds when compared to my previous OnePlus phones...
