Ways to improve the speakerphone/general volume level? topic

Hello,

I find that the headphone amplifier is very anemic compared to the iphone 5 (sorry that's what I am used to).
Surpisingly, it makes a difference to me regarding the sound quality from the device.

Also, the speakerphone sounds very quiet, as does the GPS voice in google maps.

Are there any volume related tweaks on the way for the Z1c?

Otherwise I'm pretty pleased with this device.
