Quick answer
In California you may not hold a phone while driving, even at a red light. A phone mounted on the dash or windshield can be used with a single tap or swipe. The base fine is $20 for a first ticket (about $162 with fees) and $50 after that, and a second ticket within 36 months adds 1 point.
