I recently broke the screen on my Motorola xt1080. Bought a new screen assembly with frame and installed it. Internet works, camera works, screen works great. When I try to make a call or receive a call, the screen goes black and the phone locks up. When I call out, the call does connect. The other person can hear me, but I can't hear them. I assume I did something when I changed the screen but not sure what. Any suggestions?
