Member: 1279704 Status: Offline Thanks Meter: 2 | the KM900 has a Proximity sensor so when in a call and u put the phone next to the ear the screen goes black and when u move it away the screen turns back on. if up have a screen protector try removing it or is the damage to the screen where the sensor is to the left or right of the top LG logo If your screen is turning off right away when receiving or making a call enter eng test mode dont F*** around with other seting i think the codes 1809#*900# or 18098*#900# and if you get this far scrol down to Proximity sensor and calibrated Hope this helps |
