Is there a way that the Nexus 7 stays turned on if you are looking at the screen? I'm getting tired of the screen turning off while I'm still reading...
In settings you should be able to set the sleep cycle: Settings/(Device) Display/Sleep.
Though it would be nice for your reading app to interrupt this setting, a la Netflix. Where are you having this problem?
I am testing Kindle App, Google Books, and Pocket to see if they respect the device setting or ignore it for a better reading experience. I'll edit as necessary. My device is set to sleep in a minute.
Kindle App ignores it. I'm not sure of the timeout, but it has remained alive for far more than three minutes so far, sitting on an open page unattended.
Pocket went to sleep in a minute, per my OS settings.
Google Books ignores the setting. It has been sitting on an open page for more than four minutes.
Now I am interested in finding the ceilings of these programs.
