I would send it to SONY. That is the best what you can do if you have warranty.

Try this
Disable the Stamina mode. By now it should work as normal. If it does then try the below to see if you can rectify the problem.
1. Go to phone app and key in *#*#7378423#*#* to get to service menu.
2. You should see a menu called service tests, open that and find proximity test.
3. Open it and if it shows you as ON, then you have a proximity issue.
4. Try to tap on the area where the proximity located gently and see if you can get it back on track. If it doesn't, your only choice is to go back to Sony service centre.
Good luck.

The problem was with custom rom i have installed.I have flashed the stock ftf with flashtool and now it is working .My proximity test was ok but my proximity sensor was causing problem while calling which is fixed by gently tapping the area where the proximity sensor is located.

It is not a hardware problem.
You can try to factory reset.
If it is still not working, then there is a system bug that acknowledged by Sony.
You can try to update your phone. Or wait for next new software to solve this problem.

[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.

But normally, except during calls, the proximity sensor doesn't do anything if it's activated.
Anyway, I found an app in the Play Store that claims to be able to disable certain hardware functions, but I wouldn't risk it if I were you. Something which might be safe is to re-calibrate your sensor using this app: https://play.google.com/store/apps/details?id=cn.zte.ProximeitySensorClib&hl=el
I hope that helps
Repair your mobile using PCC.. flash the latest firmware,if the problem persists then go to nearest sony center and check the sensor with them.
Thanks
Thank you guys a lot, i returned it to SONY service center , the exchanged it for me . Thanks for your help

After power button directly into standby [Proximity sensor issue?]

Hi,
My screen got broken, so i replaced my LCD and the glass. Thanks to Youtube this was easy.
The L90 boots fine, my homescreen is on screen and after that it goes in standby mode. So far, so good.
When i press the powerbutton my homescreen appears for about 1 second and goes directly into standby mode again. I dont have any time to unlock the screen.
What could be the problem here?
Question 2: how can i access my data which is stored in my phone, if i cannot unlock phone?
MANY THANKS!

- phone is not rooted
- phone is not in usb debugging mode

SOLVED. Some pressure on the proximity sensor before the power button solved my problem. Spread the word ....

Xperia z3c proximity sensor issue

I got a Sony Xperia z3c d5833. Yesterday I installed an app named pocket lock. The main feature of this app is to lock the screen when you cover the proximity and light sensor. Now the problem is just when I Uninstalled this app, the proximity sensor permanently switched ON automatically. And I can't view my screen during calls. I replaced the proximity sensor kit and also re-installed the firmware and went into stock mm6.0.1 from kit kat 4.4.4. Also installed the lollipop 5.1.1
But invain and the problem is still there. My proximity sensor kit which I replaced with another Xperia z3c is working fine in that phone.
I need help....
There is a problem with the display glass on the Z3C separating from the sensor, with an always ON sensor the result. Google and you'll find it.
You can test it in the service menu. It will show as ON, and go OFF if you lightly press on the top left corner of the display.
So you might have a hardware problem. Sometimes just glue the display corner down works.
There are also a few fixes that disable the sensor. You really do not need it. It is a battery saving feature.

All was going fine and fantastic until I installed this fckn app pocket lock ? there's no need to change the proximity sensor kit now because I already have changed it and the most interesting thing is that the faulty proximity sensor kit doing fine in another Xperia z3c. To assure myself that new kit should work fine in my phone I flashed it thrice with three different ROMS but nothing worked. Now I'm wondering how a software can damaged a phones motherboard. It means there's only two things left for me to change, Bootloader and motherboard. D5833's bootloader isn't allowed to be unlocked so therfore I can't upgrade the bootloader, now the only thing left is motherboard of my phone. .
