Screen goes black when make a call

[maxivp19]

Hello,I have the new XZ model and since last week I have strange problem with the display when making a call. The display goes black and nothing can. make it active, I even cannot close the ringing until the operator stops or something suddenly happens. It happens from time to time. I don't have protector to think this can make that problem. I checked the proximity sensor and it works. The version of the android is the last 7.0. I appreciate your help.

Hi @maxivp19,

Welcome to the community,

I am sorry to hear about this, how often does this issue occur and did this happen when running on 6.0?

This is likely related to third party software, so booting to Safe Mode as suggest will help determine this for you.

Let us know.

OK, Thanks. I will try it for few days.

Hi, unfortunately I do not have any long experience with Android 6.0 because very soon after having XZ phone I was proposed to update and within next week I did it to 7.0 version

I will try safe mode.

Thanks

Hi @sami19771,

I'm sorry to hear about that.

For how long have you been experiencing this behaviour? Did it occur after you updated your phone or installed a new application?

There is a sensor on your phone called proximity sensor that will turn the screen off when it's covered by for example, your ear when you are making a call or answering an incoming call.

The sensor is placed just to the right of the Sony logo at the top of your screen, is this covered by a screen protector or is there any dust on it? If there is no screen protector covering the sensor, try wiping at the sensor with a clean cloth and place a call.

I would also recommend testing the sensor in the diagnostics test in the phone that @uliwooly recommended. The phone should not vibrate directly when you start the test, only when you cover the sensor with your finger or if you place the phone with the front down towards a for example, a table.

Let us know how it went!
