[Q] Display doesn't turn on during / after a phone call - Xperia Z Q&A, Help & Troubleshooting

Hi!
Because I didn't get any answer in the help-thread I try it this way.
When you receive a phone call on your XZ, does the screen turn on again when you move the phone away from your ear?
This problem drives me crazy! Every phone call (active and passive...) the display of my phone turns off (as it should) when I put the phone to my ear. When I put the phone away from my head, the screen doesn't turn on again. I always have to press the power button to enable the display again. In rare cases, the display turns on as it should. But when a phone call is longer than a few seconds, the display won't turn on again.
The only reason for this problem I've found on the internet is the usage of a screen-protector. Actually I have a screen protector installed, but is has a cutout around the proximity sensor. I've also tested the proximity sensor with an app - it turns on/off correctly when I move my hand in front of the phone...
Does anybody of you experience this issue? I've tried a lot of firmware versions, but it's everytime the same... No matter if I use CM10.2 or different stock roms...
I hate it so much - not being able to stop a call before being redirected to an answering machine only because this piece of shi*** refuses to turn on the display during a call.
I'm looking forward to your answers - I can't imagine that my XZ is the only one that shows this behaviour.
Regards

is there really nobody with any screen on/off during call problems? can't imagine that my XZ is the only one... or is there an android-"feature" I donn't know?
I've already removed my screen protector... but nothing has changed...

I also have this problem frequently, i enabled power button to end calls under accessibility setting so if i press it, it ends the call, so could be partial solution to allow you to end calls, but not a real solution at all if you want an option not to end the call but to have the screen turn on only. Let me know if you find any other solutions

Actually stopping phone calls isn't my main problem. But it annoys me that I can't check the current time by removing the phone from my head for a second. Also when I have to interact with an answering machine (windows activation hotline for example^^) - everytime I have to input a number during a call this f*cking screen is off and I have to press the power button.
Don't people use their XZ for making telephone calls? Am I the only person on earth who uses the phone for other things than watching movies and surfing the net?
I also want to know if this is a general Jelly-Bean problem... If so, replacing my phone with another one would be meaningless.

Press the power button twice to activate the screen during call.

Pressing the power button ONCE also works to turn on the screen during a call. But that's the point. I do not want to press this damn power button. What does the phone has a proximity sensor for??? When I start a call and remove the phone from my head after a few seconds, the screen will mostly turn on itself. But after a while (a minute or longer) moving the phone away from the head will not turn on screen anymore...
Is it too hard for phone manufacturers to build a phone that can be used as a phone? If I wanted to have a tablet I would have bought one...

Problem solved. I have a Nexus5 now and it is just awesome. May the new owner get angry with this piece of sony sh*t.

Prximity Sensor problem....

Hi, I have a huge problem. Every time I make a call, preferably my voicemail, it asks me to press a number in the keypad.
Okay, that's fine. But the only problem is the screen blacks out immediately when the call is made and I cannot choose any of the options. I'm still in the call, although it will repeat the options for about a minute and just end the call.
I can't end the call manually or use the keypad. Tried pressing the lock button, the search, the menu, and Back button. Nothing seems to work.
Is there anything I can do about this? Because this is really becoming a hinderance.
Hi the proximity sensor should brighten the display up the moment you take it away from your ear, if it dosent prpbably there is a problem with it and you need to check it out with either the provider or HTC if you can.
normally to end call you click on the notification on top of the phone.
It is kinda annoying there is no physical button to end calls but i guess thats touchscreens for you
Probabily you use one case
that cover the proximty sensor
I don't use any case or screen protiction... maybe I should to replace it...Thanks..

I had the same problem. Hard reset solved it. Also solved a problem I had connecting with intermittent connections to Wifi. I think a bum app may have caused the problems.
Starting to happen again, not like last time though. Now it's intermitent and seem to recover when the other end hangs up. May try to get a replacement phone this time.
From what I've seen around the internet this is an OS issue... And it happens to me intermittently as well, though my lock button brightens the display... It seems to have something to do with the screen timeout and the lock screen enabling itself...
Mine had the same issue.
I would pull it away from my face, nothing.
Laid it down flat, nothing
Occasionally it would flash.
I had to return it, no problems since.
The sensor must have been loose and slid behind the open area of the glass.
If you can still, get a replacement
My replacement is in the mail. I have found that if I shake or tap the phone it will flicker and come back during a call. I think the sensor is faulty.

[Q] Screen off during call

Yesterday I made a call on the XZ and whilst I had the phone against my ear the screen switched off - this I fully expected - what I did not expect was that at some point during the call I had to press a number to get through and when I went to press the number the screen refused to switch on!! Obviously I could not press the necessary number or indeed end the call. It took me almost ten minutes of hearing the automated message trying to reset the phone (I pressed all the button combinations I knew of and even invented a few myself just in case...) without any luck! I had an idea and removed the SIM from the phone, the bl%%dy automated message still continued, I then inserted the SIM and the screen went on and the phone finally rebooted without me pressing any keys!
I had noticed before this, that the screen did remain off after my calls, but as the other person usually hung up I never really took much issue with this behaviour.
Has anybody had this problem before? My phone is rooted, with the 434 stock firmware and locked bootloader.
Do not have this issue on .434. Didn't have it on .350.
Did you install a screen protector because some of them can mess with the light sensor
Press thanks if I helped
Same issue here...very annoying!

Screen protector. Issue comes up a lot. Screen protector.
I had the same issue, I even tried to test the proximity sensor via service menu: it turned on when I got my hand near the phone, but it wouldn't turn off. I removed the screen protector, now it works just fine.
After a while I suddenly got a similar issue where my screen would not turn on when calls came in.
In the beginning i could push vol+ or powerbutton and it would turn on.
Then nothing worked. Call came in and I had to wait for the call to end before the screen could be turned on.
Tinkered around with apps to find the culprit, aaand zilch.
this was on .350
After updating to .434 (global), everything was back to normal

[Q] xperia z proximity sensor problem

any one else have this issue with Xperia Z ?
i can make calls or recieve calls and then the screen goes black when put to my ear as it should, but most of the time [not all the time] when i finish the call and take it away from my ear it wont light up so i can't end the call. i have to wait for the other person to hang up, and even then sometimes it wont light up.
they hang up the phone call doesn't end so it just stays black and i can't do anything.
i can restart it by pressing the off button and volume up at the same time, but i don't want to have to restart my phone every time i make a phone call.
has any one had this issue?
Could be software issue, ie a third party app, for example justshake and similar apps have options to alter proximity sensor activity but I stay away from altering them. The only time I have a similar issue is with modded Skype but a brief press or two of power button restores the screen so not a big issue.
You should try in service menu if your sensor is functioning properly.
A small workaround to end call without having to use the screen is to enable ens call with power button press which is in accessibility settings of the phone, so don't need to wait for another party to hang up or to reboot your phone

Proximity sensor
Mine started doing the same thing. After reinstalling and checking if it might be a software issue, I did some research and came across this: talk.sonymobile.com/thread/126533?start=0&tstart=0
I've taken my phone in, and awaiting a response. (The phone is just over a week old, so it just fell out of the "automatic RMA" period).
I put a skin on front... Now having issues... Is there a way to just disable it...

I had the same problem and did like the post #31 on the linked thread says :
Press firmly on the proximity senson with your thumb (located beside the notification led).
I have a screen protector and did not remov it and it now works like a charm.
Hope it helps.
xperia z. I have the same problem after installing the spg glass protector ver1. Since the ver2 has a cutout at the proximity sensor, I do not like it and therefore keep on using the ver1 without the cutout. I prefer to disable the proximity sensor instead of having a pit on the screen surface. Just add the line:
gsm.proximity.enable=false
to the end of the file build.prop located in /system, reboot, and the sensor will be disabled.
The way to activate the screen during a phone call is to press the power button twice.
Hope this help.
Explanation/please

Can i ask how do i reach this settings. I tryed different data searches via phone and with PC (ofc with mobile connected). But i dont seem to find this system folder no matter where i look. Maybe you can make a tutorial for me or just say where to look. Thanks
You need to be rooted. The build.prop file is in /system.
An easier way to add the property to your build.prop would be to use build.prop editor - https://play.google.com/store/apps/details?id=com.jrummy.apps.build.prop.editor
I will just say - BE CAREFUL when editing that file. If you edit the wrong thing, you can stop your phone booting.

I've tired all these solutions above but unfortunately I'm still facing same problem and it's really frustrating
My phone isn't rooted so I can't disable proximity sensor
If there is any other solutions ?
Install proximity smart cover from market. The screen will then come on when you take the phone away from your ear.
In settings:
Enable device admin
Turn screen off - never
Turn screen on - 0 seconds
Then go back and start the service

I was going crazy with this sensor problem, and tried all sort of thing including resetting my phone multiple times. The suggestion you mentioned here worked like a charm.

I have the same issue now, where/how did you enable the notifications from calls? I didn't disable anything...
Fixing Call Display
Had the same problem - goto Settings/Personalization/Manage Notifications
Select the "All" tab
Scroll down and turn on the InCallUI thingy that has the phone icon next to it
Done
Might be a little bit late, but maybe for others
worked pretty well on my Samsung S4.
download the app "proximity fix" from the playstore and run it.
Job done.
Hope that helps you or anyone who stumbles upon this!

My Z3 compact got black screen when calling and I tried all the above solutions with booting and repair of software. But the problem was due to loose screen. The glue did not hold the screen any longer. After regluing the screen, the problem was fixed:good:
I know why this happened - the display has started to peel off from top left corner - alignment of proximity sensor is messed during calls. The glue must have melted due to the phone heating up and the display must have lifted up a little.
To check if I'm right...press the screen ( top left - with your nail maybe) while making the call and the display will stay on. Please thank me of useful

im having this same exact problem right now and the same exact phone. My phone is also peeling off from the left corner and Im thinking maybe that's why it's causing these problems.
how did you re-glue back the screen.

honestly shame on sony. Such a big company that the ****ing glue is peeling off. Not even a chinese phone will do that. It's causing problems with my proximity sensor and even when i press the screen it still wont work and it only works rarely.
very frustrating problem.
My phone goes black after I dial a call. Ran tests and all sensors are not working. What do I do now?

How to stop screen for turning off when on call?

Ok so the sensor is VERY sensitive when I make calls. Everytime I call my bank and it asks to enter my account number while it's on speakerphone...my fingers don't even get close to the speaker and my screen shuts off until I put my finger far away.
Is there any way to improve or turn this off? It gets annoying when you are on the phone and trying to multi task and screen keeps turning off even though your not even close to the sensor
That is surprising because proximity sensor should be off when on speakerphone. Did you install any app which could directly affect proximity sensor? Maybe factory reset would fix that.

Yes it works like that but ur hands to close to the ear piece. Mind does that till I switch hands
BAD ASS NOTE 4 & GEAR S
When Im on the phone with somebody and i receive a text I could never use the scroll option to bring the bar down because of the sensor. What I do is hit the power button on the side of the phone, then hit it again and sign in with my code, then i dont have the sensor problem anymore. I will still be on the phone and Im at the homescreen. Thats the only way around it for me. its real quick too.
Solution
I am on the phone all day and need the screen to not time out because I am on and off the mute button a lot.
I use Call Light to make sure I always have the screen on when on a call.
Hope that helps some.
