Phone unlocked problem during call (z2)

[DBZ2]

With my new update to marshmallow, I can't unlocked my phone (Z2) during calls anymore. Is it because of the new updates or because of my settings. Please help. Thank you

Check the following:

- screen protector that might be thicker and could be covering the proximity sensor

- any dirt or grease that might be found on the sensor that could make it malfunction, keep in mind that it is very sensitive.

Screen protector is the same when i have lollipop version and i don't think there will be dirt on the sensor because after I bought my z2 I didn't even change my screen protector. But I think some sensor problem because when I use to have lollipop version if I keep my phone horizontal I can unlock but in other positions I can't unlock and now after my marshmallow update that doesn't work anymore. So is it because I change some of my settings which I was but couldn't remember or because of the new update?
