Hi.After update to 5.0.2,These problem happened.Factory reset and PC companion don't help.Even at 4.4.2 and 4.4.4 they were broken ,too.

Does that mean it is a hardware failure?

But how can they be broken at the same time when update to lollipop?

Every tests passed except Ear proximity

And in service menu it looked like this

And these meter readings don't change no matter what i do

Check the proximity sensor. Do you see anything blocking it or covering it. For example: any film, or plastic covering, or even dirt or debris?

If you are having trouble locating the proximity sensor, take a look at the link below.

I don't exactly know where it is.Near the LED light,with the light sensor?

The light sensor is funtioning well.

I think nothing blocks it.

Contact Sony xperia support that seems to be a hardware issue.

Well,thx anyway.

But i can tell they would say the mainboard were broken,Need a replacement....

I can found numerous people get dead sensor in updating.

Does that mean updating software might damage the hardware?

I have an Xperia Z running lollipop now, I can't recreate your issue.
