Proximity sensor stopped working after an update to ww_18.1220.2111.160
Screen goes black right after call (cell, WhatsApp, FB, etc), screen gestures doesn't work anymore, etc.

Today i've got an OTA update to ww_18.1220.2111.164
Nothing changed with proximity sensor:(
DevCheck shows that the sensor is alive. It starts showing 0cm distance when I put my finger over the sensor.


Is there a chance to get any support from ASUS here?
