I'm using Samsung Galaxy Ace and i usually connect it to Kies to update the firmware. But now the current update has brought about lots of changes... the task bar icons have become smaller, lost the glossy look, battery icon is smaller and my phone does not ring!! i tried assigning different ringtones still it wont ring. there is nothing wrong with the speaker as i can easily hear music....please reply as soon as possible...
