How to Take Pictures with an Android Phone
To take a picture with your Android phone, point the camera at the subject and touch the Shutter button, either the touchscreen shutter button or the phone’s physical shutter button, if it has one. Your Android phone's camera display may look something like the following figure.
After you touch the Shutter button, the camera focuses, you may hear a mechanical shutter sound play, and the flash may go off. You’re ready to take the next picture.
To preview the image you just snapped, touch the little icon that appears in the upper-left corner of the screen.
The camera focuses automatically, though you can drag the focus square around the touchscreen to specifically adjust the focus.
You can take as many pictures with your phone as you like, as long as you don’t run out of storage for them on the phone’s internal storage or MicroSD card.
If your pictures appear blurry, ensure that the camera lens on the back of the phone isn’t dirty.
Use the Gallery app to preview and manage your pictures.
Deleting an image immediately after you take it with an Android phone
Sometimes, you just can’t wait to delete an image. Either an annoyed person is standing next to you, begging that the photo be deleted, or you’re just not happy and you feel the urge to smash into digital shards the picture you just took. Hastily follow these steps:
Touch the image preview that appears in the upper-left corner of the screen.
After touching the preview, you see the full-screen image.
Press the Menu soft button and choose the Delete command.
Touch the OK button to confirm.
The image has been banished to bit hell.
If these steps don’t do the job, remember that you can always delete (and manage) your images by using the Gallery app.
Setting the flash on an Android phone camera
Three flash settings are controlled by the Camera app. To change or check the flash setting, open the control drawer. You should find the flash command button there. If not, the button may be found directly on the touchscreen or by pressing the Menu soft button.
A good time to turn on the flash is when taking pictures of people or objects in front of something bright, such as Aunt Betty holding her prized peach cobbler in front of a nuclear explosion.
Icons representing the flash setting may appear on the screen when using the Camera app, or they may replace the flash command button on the control drawer.
