Hello people! I'm having some troubles with my galaxy Vibrant... The volume buttons switched! its like, when I press vol up, it goes down, and when I press vol down it goes up " the other problem is related to the sound too.. I have no external sound in my galaxy, but when I plug my earphones, I can hear everything normally! It's a little weird, the phone thinks the earphone is always connected, and when its actually connected, the phone thinks that it isn't! My vibrant is in firmware version 2.3.4 ! Please, someone help me, i cant use the phone, it is powered off since 2 months !
