Its been a while after LG released its 2nd model of its flagship device with the knock feature. Initially this feature allowed users to double tap the screen to turn on the device instantly instead of using the power button and LG has seen that people loved this feature. Now, LG has decided to give updates on all LG L II series smartphones in the upcoming month. They have also decided to add this feature on all their upcoming devices, But availability will be depending on region and carrier, so you might have to wait for a bit longer for the feature.
