Summarize this article in one sentence.
It's at the bottom of the Home Screen. Tap the Camera app icon, which usually resembles a camera or the outline of a camera. Your tablet's Camera app might be named something other than "Camera", so look for the camera-shaped icon here. Your Camera app will usually open to the "Photo" mode, but most tablets allow you to record video by swiping left or right over the "Capture" button that's at the bottom of the screen. Aim your tablet's camera at something that you want to photograph (or video tape). You can also change the tablet's view to the front-facing camera (e.g., the camera on the screen side of the Android) if it has one by tapping the circular arrow icon. Tap the "Capture" button, which is a circular, white button at the bottom of the screen. This will take a photo and automatically save it in your tablet's Photos app. If you want to record a video, tap the red "Record" circle instead to begin recording. Tap this circle again to stop recording and save the video. Every Android tablet comes with a Photos app in which your taken and saved photos and videos are stored. You can find this app in the App Drawer and open it to view the photos/videos that you've taken or saved. You're almost done acquainting yourself with your tablet! The final thing that you should do is create a passcode to secure your tablet. If your tablet already has a passcode, you're all set.

Summary:
Open the App Drawer. Open the Camera app. Select a capture mode. Point the camera at a subject. Take a photo. View your photos and videos. Return to the Home Screen.
