I am having a few issues with music on my fone (htc sensation xe) running jellybean I copy music via us to my sd card (8gb). It works for a while. But if I clear my temporary data the phone erases all my music. I have astro file manager and that us showing the music folder as empty too as I thought it may just be the standard music playing software. Any idea why this is happening? Is the phone recognising mp3 as a temp file? ,a potential fix (without installing anything unnecessary) Hope it can be sorted, I'm not due an upgrade for a long while.
