Basics of Android Phone-An Overview

The Android operating system has been developing fast since the release of Version 2.x (ranging from Eclair, Froyo to Gingerbread) for smartphones and Version 3 (Honeycomb) for tablets. It achieves another great milestone with the latest Version 4 (Ice Scream Sandwich or ICS), a universal system suitable for running on both smartphone and tablet devices.
If you’re using a smartphone running on the Android version 2.x, you will be familiar with the four hardware buttons—Back, Menu, Home and Search—to interact with the system. Borrowing the design built for the tablet, Google’s flagship smartphone Galaxy Nexus running on Android 4.0 now has no hardware buttons on the front, not even one. These hardware buttons turn virtual, leaving only two physical buttons—Volume and Power—on the left and right sides of the device.

Like the screenshot, the three buttons Back, Home and Recent Apps often appear on a home screen and the Menu button only shows up when an app needs it. When you playback a video, the default media app hides all these onscreen buttons and takes up the whole screen area for your video. A pretty good idea.

If you’ve just got a new Android device running on Version 4.0, these tips and tricks might be of help to you. Some relevant information on older versions of Android is added for ease of reference where applicable.

Conference call

 A conference call is a telephone call in which the calling party wishes to have more than one called party listen in to the audio portion of the call. The conference calls may be designed to allow the called party to participate during the call, or the call may be set up so that the called party merely listens into the call and cannot speak. It is often referred to as an ATC (Audio Tele-Conference).

Conference calls can be designed so that the calling party calls the other participants and adds them to the call; however, participants are usually able to call into the conference call themselves by dialing into a special telephone number that connects to a “conference bridge” (a specialized type of equipment that links telephone lines).

Companies commonly use a specialized service provider who maintains the conference bridge, or who provides the phone numbers and PIN codes that participants dial to access the meeting or conference call.

Three-way calling is available (usually at an extra charge) for many customers on their home or office phone line. To three-way call, the first person, who is the one who someone wishes to talk to is dialed. Then the Hook flash button (known as the recall button in the UK and elsewhere) is pressed and the other person’s phone number is dialed. While it is ringing, flash / recall is pressed again to connect the three people together. This option allows callers to add a second outgoing call to an already connected call.
