When recording a video with specific background music from our iPhone, the limitations of iOS (probably due to the copyright of the songs) they don't let us do itAs the camera is activated, the music stops. However, with the new iPhone 11 it is possible. And no. It is not a new feature available in iOS 13.
It is a characteristic that It is only available in the new iPhone 11, so we can consider that it is not in iOS 13. This function allows us to quickly start recording videos while we are taking pictures thanks to the QuickTape function. This function activates movie recording mode when you hold down the shutter button.
Furthermore, this function also allows us to lock the video mode by sliding the shutter button, so it is not necessary that we are pressing the button on the screen. If we are playing music from our terminal, the music will not stop at any time during the recording, so it allows us to unleash our imagination when creating videos, since on many occasions, it is the music itself that gives meaning to images.
The QuickTape function, only available on iPhone 11, iPhone 11 Pro and iPhone 11 Pro Max. Unfortunately, Apple has not bothered to include this function in the previous version of iPhone, iPhone XS, a terminal that has enough power to be able to use this function. The same happens with the night mode, another of the functions with which Apple encourages the renewal of the terminal by the user.
Now that the jailbreak has become part of Apple's history, we cannot expect a feature similar to QuickTape from this community. Nevertheless, with the night mode things are much simpler. Through the App Store we have at our disposal the NeuralCam application, an application that allows us to offer results very similar to those that we can find in the night mode of the iPhone 11 with the old iPhone.
But it can be done on WhatsApp by recording videos and with music.
