Why does my Yoyo (S) turn off whilst music is playing?

The Yoyo (S) has an Auto Power Down (APD) feature that causes the speaker to power down after 10 minutes of inactivity. However sometimes, when the audio source level is low (e.g. phone, tablet etc.), the device will register the signal as lower than the APD threshold.

To avoid this please ensure that your mobile device's volume is increased to above 50% or more.
