I am on my 3rd Propel because the first 2 were crap. This one doesn't seem to be much better. It drops calls and cuts out when I have 5 or 6 bars, it has feedback when I use the speaker phone, sometimes I can't hear the other person or they can't hear me, sometimes there's horrible screeching interference. This happens about 4 out of 5 calls. Has anybody else had the same problems?
