Hi, I'm a complete newbie here so hope I'm doing this right. I currently have a music app on my Galaxy S21 Ultra, DFX Player Pro. I've been advised that this app is outdated and may not work properly, but has been fine so far. I thought I should prepare myself and install a newer app. My question: Is there an app I can install that will allow me to transfer music files to it from the old app? Thanks in advance.
