i dont have the dropped calls issues wince the update, but my bluetooth has went to hell.
for some reason it seems to turn off every night on its own. then to get it back on i have to go to settings and click the checkbox to turn it on, and wait.
and it still doesnt turn on.
after a couple minutes, i have to click the checkbox AGAIN, and then finally after a minute it turns on and connects.
FRUSTRATING!
Thats the only issue with android is who do you call for support?! tmobile? samsung? google?
