I may be missing this, but it looks like Verizon has removed some of the Samsung Apps. If anyone knows how to get these (apk post), please let me know.
In the Global User manual it is noted that there should be a "Samsung Apps" or "More Services" in the App drawer. Inside of this, you can install some of the Samsung apps such as "S Baro". This is a barometer using onboard sensors. There are also various other samsung apps which you can not find in the google play store such as a family file share program, photo editor, etc.
The Samsung Apps website allows you to download an apk for older devices (not ICS).
