Most phones these days offer call waiting, and the Droid X is no exception. When you’re on one call, you’ll get a notification that another call is coming in. You can then choose to either answer the call, putting your first caller on hold, or to ignore the incoming call. And if you’re a real multitasker, you can stay on both calls simultaneously, hopping back and forth between them. Do that, though, and you risk making both callers feel slighted.
When you’re on a call and another call comes in, your screen shows you the phone number of the second caller. The phone won’t ring or vibrate, and at that point, you’re still on the call with your first caller. You have two choices:
Answer. Tap this button, and you immediately switch to the second call. The first is put on hold. Make sure to tell the first caller you’re putting her on hold, or else you’ll lose a friend. When you answer the second call, a green button labeled “Switch Calls” appears onscreen. Tap it to switch between the two calls.
There’s one annoying oversight with the way that the Droid X handles call waiting: You can’t end one call and then talk on another. When you tap “End call”, you terminate both calls. However, there’s one saving factor—if you’re on one call and tap “End call”, the other call is also terminated, but that person’s phone will immediately call you right back.
Ignore. Tap this, and the incoming caller will be sent into voicemail.
