Whatsapp: Activate preview in lockscreen
With WhatsApp you can activate a preview on the lockscreen - at least on Android. So you can see incoming messages despite the lock screen and can reply to them without unlocking the phone.
Turn on pop-up notifications in WhatsApp
- Open WhatsApp on your Android smartphone.
- Press the menu button and then "Settings".
- Go to "Notifications"> "Popup Notifications".
- In the new window you have three options for which the popups can be activated: Only when the display is switched on, only when the display is switched off or in both cases.
- Tap the desired option and confirm the setting.
These instructions refer to WhatsApp version 2.11.186 on Android 4.4.2. Also read how to add WhatsApp as a lockscreen widget on your lock screen.
