Hi Pedro,

this problem also exists on the RARZ V3x and I called it ByeByeMoto,
because it stalls my complete phone. There can't be an easy workaround.
It is a really serious bug from Motorola and they should provide free
software upgrades to anyone. However I have no idea how they passed the
Bluetooth qualification with these devices.
Regards
Marcel
