there is no difference between touching and pressing on the home screen button
About a week ago I bought my phone. (iPhone 7plus) My phone notification settings are set to "Settings -> Notifications -> preview -> when unlocked".
In the first days, when I was in the lock screen of the phone, I could see the notification contents by touching the home screen button. So I did not have to press the home screen button, just touch. The contents of the notifications on the screen saver were visible as the lock was unlocked. The notification bar at the top also wrote a notification that the screen was unlocked.
I made some changes in my settings so that my phone is new and this mechanism changed after some changes. Now there is no difference between touching and pressing on the home screen button. Either way, the screen is fully opened and the screensaver comes out. If so, I see either the last application on the screen or the icons on the home screen. I need to go back to the notification screen or open it to see the notification content.
How do I get back to my initial settings?
