Hi. I'm new here, and new to iOS as well. I've just got an iPhone SE. So far everything is ok, except from one thing that keeps bothering me. When the phone is locked, everytime I get, for example, a whatsapp message, the screen turns on for a few seconds. I don't want to disable notifications on the lock screen. I just want the screen not to turn on everytime I get a notification; I wanna see them unlocking the screen manually. Thanks!
