Once that’s done, go to the Play Store and download an App called Re Scan Media and run it. Wait 5 minutes for the device to re-scan your media.

If you still cannot play your music, then try turning your phone off and removing your SDCard / memory card (if you have one). Then turn the phone on without the card. Then turn it off again and reinsert the card. Finally turn it on again with the card back in.

If you still can’t play music, then some users have said that there may be a conflict with the Twitter App. Try uninstalling this and see if the error persists.

You can also try downloading some new media player from Play Store and try running media on this new player.
