Verizon has added a simulator for the Samsung Galaxy Nexus, running Android 4.0, on its Web site.
This offers potential buyers a chance to see if the new flavor of Android is for them. The simulator will let you check out most of the basic functions, and also some of the newer ones, including the ability to dismiss incoming calls with a text response (as shown below).
You can find the simulator here.
Here's how to use it:
Step 1: Click on a general topic in the left-hand pane of the simulator. Here we'll look at Phone Calls.
Step 2: Find an interesting subtopic within the list that appears. Here you see the options for Ignoring a Call and Sending a Text Message.
Step 3: Click on the red-highlighted areas that appear in the middle of the simulator. (The instructions on the right will explain what you're doing.)
The right-hand pane will say you've completed the steps once you're finished.
While this may not be a real substitute for holding the phone and actually using it on a day-to-day basis, it's certainly a fun way to look at how some new features of Android 4.0 work.
