How to prevent iPhone screen from turning off after push notification?
I have an iPhone 5S.
Some program sends me a push notification.
I put the iPhone to sleep (quickly and once press the Power button). I receive a push notification, the screen lights up for 1 minute, and then goes out. Since the screen went out, I don’t know that I received a push notification. How can I make sure that the screen doesn’t go out after the push notification arrives?
What doesn't work: Settings - Display & Brightness - Auto-Lock: Never.
iPhone 5s, iOS 12
