Okay this problem I am about to explain to you has happened twice, maybe 3 times now, and I MUST figure out what is going on. I have all my sound settings turned on, ringer volume, touch pad noise etc.. normally when I touch something on my phone it makes a click noise.. but for the second time (atleast), when I try and make a call, or receive a call, I can not hear ANYTHING, it's as if it's mute. BUT if I click speaker... I can THEN hear sound and listen to whatever is on the other end of the line. But if I click off speaker it goes right back to not being able to hear anything... I know something is up because when I push the dial pad to make a call, it doesn't make ANY sound, even when that sound feature is enabled. I hope I've explained myself enough for you to understand my issue... The first time I remedy the problem, i rebooted my phone... but I don't want to do that quite yet because I want to figure out the problem.. can ANYONE help me?!
