I try calling via NITdroid to my dad

it can call. but i hear nothing neither from it or from his phone.

i've tried reinstall and do it again but it was the same.

how should i do?

and my back button is the soft-touching camera button (i don't know how to write this = =) while it should be the lock button

is this serious?

thanks for any helps !!

sorry for my poor English = =
