I have a problem issue on nexus 10 when I using portrait to read or watch youtube on nexus 10, it sometime went blank and automatic lock and I have not unlock again but few second again it lock again. But when I turn to landscape usage, it show no problem.

anyone has this kind of issue. any advice to resolve this issue. thank you
 
Sensor? where to off the sensor? I do not cover the sensor. I just hold upright in portrait to read news but it off suddenly and I have to unlock again.

Please advise.
 
could it be inactivity? Perhaps when holding the Tablet in landscape you are touching the screen in a way you do not touch it in portrait? Check Settings>Display>Sleep and see what setting the screen is set to shut off at.
