Default [Q] N7 2013 LTE: No proximity sensor?

Hey,

I searched so hopefully did not miss this elsewhere.

I just bought the 32GB LTE version, popped T-mo sim in it- all is peachy as can be (free 1GB a month.. woot!)

However I am trying to have a way to turn on the screen without the power button (since in some case positions the tablet rests on the power button.

The apps I installed cannot see a proximity sensor on the device. what I have been able to find ounline the LTE version was to have a proximity sensor on it. Did I read wrong?

Help?

2013 N7, 32GB, LTE, 4.4.3 in USA.
