How do I find Music (version4.40.23) to download?

[AC Question]

This Music Player (version 4.40.23), came with my phone and I'd like to be able to have my brother download it to his phone so that he can listen to my extensive mp3 collection I sent him on a 64gig sd card. (The musicplayer appears as a purple square with two upright connected white notes)

Use a program to backup your apps to a pc and see if it backs up the apk file. If that doesn't work it's probably in built somehow so won't be possible
