Is there a way to keep the lock screen on longer? It seems to turn off within about 5 seconds sometimes, though at other times it may stay on for maybe 15 seconds. Sometimes, I turn it on, but before I can swipe or fingerprint the device, the screen is already off again.
Have you adjusted the timeout in your settings?

Settings --> Lock screen and security --> Secure lock settings --> Lock automatically: choose time from 5 seconds up to 30 minutes.

Sadly, this sets the time the phone will lock after the screen times out, not the screen on-time before the display shuts off. I still get a 5 second delay before the screen shuts off, even after I set "Lock Automatically" to one minute...
