[help] xolo q700 dissplay issue

[phuchungbhutia]

i bought xolo q700 few days back. i have this strange issue with its display.
everything is working fine and i love this phone. but when i call any number the screen goes off. i cannot see options to put it on loudspeaker and most importantly i cannot use the dialer. also i cannot be sure if i have dialed the right number. the screen just goes off. physical buttons only of volume rocker and power button and it cannot bring the display up.
is this manufacturing defect or is this something to do with display settings (i checked but couldnt find any setting regarding it). is it same with any other jb 4.2 phones?.

Try reseting the phone

the proximity sensor/light sensor of your device may have been covered by the screen guard, try cleaning the dust around it.
