Okay so I just got my Samsung Reality tonight and for some reason, when I call someone, there's options on the screen during the call such as mute, speaker phone etc. But during the call, the phone locks to prevent my face from pressing buttons, but when I try to unlock it to mute or speaker phone etc, It locks up after a split second of me unlocking it...What am I doing wrong? How do I fix this where I unlock it during a call and it doesn't lock up really fast when i'm trying to see my on screen options and who i'm talking to?
