I have a Galaxy S9 and want to change the native screen lock sound to the iphone x lock sound. I have installed a few different remapping apps and then uninstalled them because they didn't work well.

The problem I have is that it takes about 2 seconds after I press the power button hard key before I hear the iphone x sound. But when I unlock my phone the sound is instantaneous. I just want to find where that native screen lock sound is in my file explorer and replace it with the new one.
