How to reply to messages from the lock screen (PRO method)
Image above: Respond WhatsApp from Android notifications, on locked screen
If you have a device with Android 7 or higher, you don’t need to install an additional application to answer messages without unlocking the screen. The feature is already integrated into this system. You just have to activate it.
By default, in Android 7 you can reply to messages from notifications directly. What you can’t do is reply from the lock screen. If you expand the notification you will see that the cell phone requests to unlock the screen before being able to respond .
To be able to reply from the notifications on the lock screen ( without having to previously unlock ), you must enable this function. However, the procedure requires the help of a PC.
On Samsung Galaxy
The process has been tested on a Samsung Galaxy S7 Edge , but is likely to work on other devices.
The fundamental requirement is that they have the Android 7 «Nougat» system.
Additionally, you must prepare your PC and cell phone to be able to send a couple of text commands from the first to the second. You need to install and configure the ADB tool on the computer. You must also install the mobile USB drivers. On the cell phone you must enable USB debugging.
Once the above is accomplished, the mobile is connected to the PC with the USB cable. The ADB tool runs on the PC. Type the following command and hit Enter:
This should return a character string, confirming that the connection between the computers is correct . Then the following command is entered:
adb shell settings put secure lock_screen_allow_remote_input 1
This command is the one that enables the response from the notifications on the lock screen . It usually takes effect immediately. You don’t even need to restart the device.
If you receive an SMS, WhatsApp or Messenger , check it. In a new notification, swipe down. A text box should appear so you can respond directly from the notification on the lock screen, without having to unlock it first.
How to undo this change
Being able to reply to WhatsApp and other messages without having to unlock the screen is very useful. But it also opens up the possibility that anyone in the possession of the phone can reply to your messages . To reverse the previous process, send the following command:
adb shell settings put secure lock_screen_allow_remote_input 0
