My question involves a traffic citation from the state of: California

Is there a standard cost for a first offense for using a cell phone? I was charged $132- for the citation in Redwood City, CA. The officer at the time said it wasn't a big deal, but I was surprised to see the first offense be $132-.
I've seen some documentation saying $20- for the first offense.

If that is not what is suppose to be the fine, since I already paid $132-, what recourse is there if any.

Thanks in advance
