[q] [help]screen freezes during call sony xperia z2 - Xperia Z Q&A, Help & Troubleshooting

Hi everyone,
I have a Sony Xperia Z2. Since about a month now, everytime I make a call, or receive one, my screen freezes to black during the call. I cannot hang up, I cannot put on loud speaker nothing as screen remains black, even when I try unlocking with the power button, nothing happens. I have tried reseting my phone to factory settings, still the same. When ever I am on a call it does this. Even on whatsapp calls. Please can anyone help me fix this

I had the same problem with my XZ.then I removed the screen protector,which was blocking the proximity sensor,that's why the screen remained black during calls.
try removing the protector or tempered glass or anything that can block the proximity.

[Q] Low ear piece volume bug/Also Lock Screen Issue

On my Sony Xperia ZR (Latest firmware) I am noticing that sometimes when I make calls the ear piece volume is very very low. Other times (usually after a restart) it is working fine again...anyone else notice this?
Another Issue I am noticing is that after installing google now and then disabling it when I lock my phone. On the home screen I am no longer taken to the time as per default but to my keypad and text saying "get google now" any idea how to make the phone default lock screen the time without installing any 3rd party apps?

Sounds to me like you're covering the proximity sensor, all depends on how you're going about using the apps. be a little bit more careful not to cover the sensor and you'll soon figure out how to work around it. It's fairly sensitive to be honest.
Also, if you use screen protector. That will also block proximity sensor too.
Phone thinks, like, you are holding phone on your face, soo turn off screen, to prevent miss touch any button.
Proximity sensor is at upper right position. You will see that two point. One of them is ambiance sensor for calculate screen brightness, other one is proximity sensor.

Microphone and screen-on issues

Hi all,
I've come across a couple of problems with the phone that I've put down to manufacturing, but I'm not really seeing anyone else complain about them. I'd just like to see if anyone else is experiencing these issues or if I should have my phone replaced under warranty.
Issue 1: Microphone.
During a call, people can hear me clearly, but if I switch to speakerphone (or use an app like Skype or Viber, which usesspeakerphone for video calls), they have trouble hearing me. I know there is an issue where the mic stops working for some people, but mine is still working...only I sound very faint to the other person. If I bring my face right up to the phone and speak, they can hear me somewhat clearly, but it defeats the purpose holding it to my face when I'm in a video call.
Issue 2: Screen touches during a call.
I've noticed that when in a regular call, the screen turns off when I bring the phone to my face, and turns back on as I pull the phone away, which is fine. The problem is though, that while the screen is off and pressed to my ear, shortly after the light of the screen turns back on and it seems I've been pressing things with my ear, e.g. pulled down the notification shade, opened an app on my home screen or opened my app drawer, etc. Is anyone else noticing the screen turning back on mid-call? Or does anyone know if the screen still responds to touches even though the backlighting is off? Or is this an iPhone 4-esque situation where I'm "holding it wrong"?
Thanks guys
I take it the lack of responses means that no one else is experiencing the issue and that I should swap it under Warranty :/

Never faced any of such issues with my nexus. You should go for a replacement

Mute randomly activates during calls

I'll be on a call and the other person will suddenly be unable to hear me. This happens with stock and Pure Nexus (running on both elemental and shamu). It doesn't happen regularly. It hasn't happened in weeks, but yesterday it happened twice on one phone call and once on another. I can fix it during the call if I mute and unmute the phone on the display. When the phone mutes itself, the display control doesn't show that mute is active, only I after I press it and "activate" it.
I used to think it might have been my face pressing against the screen, but that can't be it as the screen is off while I'm talking. In order to fix it during a call, I have to turn the screen on first. Has anyone else had this problem?
I had this problem and found call screen lock in the play store (which solved it). It turned out I was somehow tapping mute with my face while on the phone after not tripping the proximity sensor...
It only happened rarely, but you can tell if you might be doing this if your screen occasionally wakes up while on the call without being pulled away from your face (the proximity sensor thinks it is not close to you face intermittently).

Question Screen Turns OFF on Video Call (Viber)

Hello,
Just wondering if you guys have the same problem.
Phone is updated on 12.5.8.
Just bought for my wife last week
The app we are having trouble with is Viber during Video Calls. Whenever she video calls someone, while it is ringing, the screen turns OFF. Nothing happens even if she double taps the screen or presses the power button. After a few rings and presses on the power button, the screen will turn ON and everything seems back to normal.
I tried video calling via FB messenger and I am not encountering the same issue.
I tried to test the proximity sensor using Viber call and phone call and it is responding well but not 100%. Sometimes when I put in on my ears, the screen doesn't turn OFF. Most of the time, it does.
I also tested via the CIT (Secret Menu in the About Phone>Kernel Version), the result was mixed. If I just put my hand over the sensor, it does not turn to 0.0. It only goes to 0.0 if I put the phone down facing the table and then goes back to 5.0 when I pick it up.
I tried clearing cache, data, uninstalled, reboot then installed viber but the issue still exist.
Here is a video link of the issue I am talking about

Do any of you face the same issue? TIA!
