Why does my phone not have any audio?
Can't hear music.
Check that you don't have the phone on mute or the volume settings are on low. Check the phones volume by pressing the volume button on the phones left side. If this does not work, turn phone on and off to see if this resolves the issues. If you try all these and still no audio see guide for Speaker Replacement www.ifixit.com/Guide/BLU+Studio+5.0+S+II+Speaker+Replacement/33243
