About the XZP Speakers

[cloudstrife1ph]

Is it just my device or the bottom speaker is slightly weaker than the top one? Are they trying HTC's tweeter - woofer?

And can anyone explain to me why the back center part vibrates when the volume is high?

>why the back center part vibrates when the volume is high?

parts of the phone resonating. perhaps it's more noticeable than in other phone models because of the materials used or the arrangement of internals under the back panel, but it can't be fully avoided.

Faulty unit. Replace it. Had the same problem with Z2 and Z5, shame they still didn't improve on quality control with XZ series.

Both Z2 & Z5 replacement phones had equall volume so definitley hardware fault.
