1st problem is that the sensor is very badly calibrated imo compared to my old nexus4 and 2nd problem is that if your screen goes black when sensor is triggered, you can still do touch inputs. Screen should be locked if sensor is triggered as on many other phones. I checked this with someone else who owns a z2 and he was pretty sure it was same for him.
Im gonna doublecheck with two more z2 owners as I dont know that many z1c owners irl.
Only me or any of you also notice it?
