My 7100t does not work inside any building! My phone mic seems to be muted not allowing me to talk. I can hear everyone else fine, but they say my voice is very weak/faint and hard to hear. I dont usually experience this problem with the phone outside, but sometimes I do. It seems that anytime my phone is under a roof it can not transmit data or get a good signal even though it says I have good signal strength in the top corner.

Are there others with this same problem?
