If the Do Not Disturb is enabled, calls and alters will be prevented while the screen is locked. You can go to Settings > find Do Not Disturb and turn it off.

3. Turn on Allows Notifications

You may think this is too obvious and you have turned on the notification before.  An iOS update may change the settings, therefore, go to have a check.

Go to Settings > Notifications > Show Previews > choose "Always". If you set it to "When Unlocked" or "Never", the notification won't work when the screen is locked.

4. Turn on Notification for Certain App

Although you have turned on notification, you still can't receive the notification from a certain app with the notification off.

Go to Settings > Notifications > tap the app with no notification, like Messages > turn on Allow Notification > turn on Show on Lock Screen and Show as Banners. Besides, tap Sounds, if the ALTER TONES is set to None, reset it to any other way, like Note, Aurora, Bamboo or Chord.
