Is there a way to stop my iPhone from falling asleep while using Apps such as YouTube and Twitch without completely turning off Auto-Lock?

Added (1). I don't want to disable Autolock, because I still want my iPhone to lock when I'm not using those apps.

Yes. Go to settings, then display and brightness and change your auto-lock time. You can even set it so it never auto locks.

  • What is it with Twitch and my laptop? I have recently joined Twitch (a gamer stream website) on my iPhone and when I go on Twitch on my laptop it comes up with mostly white, (see picture) and I knew some thing didn't look right, so I went onto my mothers laptop and it came up with a totally different look.
