Problem:
The volume is low when using the Mate X7 series phone for a handheld call.
Solution:
The phone's receiver is on the right side, and the effective speaker holes are also on the right. Therefore, when you hold the phone in your right hand, the volume may vary depending on how you hold it. When you feel the volume is low, adjust the volume and the holding position. Try to place the centre of the speaker holes in the centre of your auricle.
