My first tablet & I'm about ready to throw it thru the wall! The stock MP3 Player was horid so I downloaded a better one. I know about setting defaults. But the stock player did an auto-update and now it's the only one the system recognizes. The culprit is Google Play Music. I can still start up my fav player but clicking on an MP3 only does Google, no choices offered & LAUNCH BY DEFAULT is clear. Then text editing is flaky. The cursor randomly jumps to different lines. I'm sure it's this new Android 4.1 OS & Google Play Music. I'm NOT impressed with this Hi-Tech CRAP!
