Is there a clever way to prevent sleep mode on mobile?

An UE4 app on my Nexus5 always goes into sleep mode after 30 seconds inactivity. This is unfortunate when it comes to long cinematics and passive events.
Is there a way to prevent sleep mode without doing it manual in the phone settings?

Also is it possible to get the sidebar (With “global back” “home” “tab”) to autohide?

Any answers on this? I’m kind of stuck with this problem also…

I too would like a answer to this.
Sleep mode really messes my UE4 app up.

For preventing standby use “Control Screensaver” node.

In my case UE4 crashed on standby when using API level 14, fixed when changed it to 10.
