Hello, Is there any ways to see the original Android system files from a PC, without rooting the phone? I would like to access to the folder that stores all the default ringtones / notification sounds. If there are no ways without rooting the phone, then can somebody help me finding the correct documentation to root my Meizu 15 Light (M87H), Android 7.1.2? I can't find anything solid. Thanks a lot! Friendly.
