Samsung SGH-A737 / SGH-A736
Terrible internal antenna
It doesn't matter how many bars of reception I have, about every 4th word of mine gets dropped AND I'm always having to ask people to repeat themselves.
I know it's the phone because other AT&T phones don't have the same problem in the same places.
Otherwise I love this phone, but this is a terrible terrible flaw and I will have to get another phone because of it- I run my business using it.
