The following I am observing so far

low signal strength
very slow moving from screen to screen
while on a call, the lowest volume is very loud and crackly, when I turn the volume up, it barely gets louder
when on a call and the dial pad is up, my face presses numbers
gmail is slow
vibrate not as strong

I'm not experiencing any of that. In fact, I'm now getting a solid 2 bars 4g in the same places it used to switch to 3g.

My screens fly... very fast switching from one to another
No incall volume issues
gmail is just as fast as it was with ICS

Sorry I'm not experiencing any of that either. Have you rebooted since updating? If you have try a factory reset and I bet that all goes away

Actually, 4G signals on my phone seem to have gotten better. It is smoother than before, too. Volumes seem the same to me and phone dialer works like before. I think you need to reset.
