If you've set a pattern, PIN or password, you can control which notifications show on your lock screen.

1. Go to Settings > Security & Location.
2. Touch Lock screen preferences > Lock screen.
3. Select whether or not to show notifications. If you show notifications but hide sensitive content, then you'll get notifications for an incoming email or chat, but they won't include message details.

To add your name or a short message to your lock screen for anyone who finds your phone:

1. Go to Settings > Security & Location.
2. Touch Lock screen preferences > Lock screen message.
3. Type the text to display and touch Save.
