Dear all.... I am using Samsung Galaxy Ace GT-S5830i. 1. When i use sip call in Fring or Nimbuzz, I can hear what they say; but they can't hear what I say. When i use ear phone both can hear. Can't I use without ear phone? 2. The phone memory is, as you know, only 190 MB. So when I install any software, some programs are installed in phone memory and some are installed in sd card . When the phone memory is full we can't install anything more. So I want to know if there is any option so as to transfer the installed programs to SD card memory, or can we set the SD Card as default? Pls help dears... If more doubts I will be with u later. Thanks in advance.
