Is 5 minutes the maximum time before the screen goes blank? Someone in a post elsewhere said he had set his phone to "never" , but how?
Sorry but my Lumia 520 has the following:-
Settings>lock screen>"Screen times out after">only four options here - 30 seconds, 1 minute, 3 minutes,5 minutes. "Never" is not an option.
So, is that it, that is all I can do?
