Samsung Galaxy Nexus

After the famous GOOGLE NEXUS, here comes the Samsung Google Nexus with lot more features having Android 4.0 version in it….Its surely gonna rock the range of Android phones….

The phone and the Ice Cream Sandwich (ICS) operating system, there’s a lot of minutiae, more than most people will really want to read regarding the scads of cosmetic and substantive changes to each function or app. As a result, I’m aiming for the broad view. In the three weeks since I got the phone, I’ve answered many of your ICS and Galaxy Nexus questions, tested the camera, stumbled onto a lot of hidden features, and explored Android Bemusing another Galaxy Nexus phone (more on this below).

Using ICS on the Galaxy Nexus has been a positive experience, and as with many phones, the Galaxy Nexus grew on me even more. It has an open design and appealing shape, a comfortable “hyperskin” soft-touch back cover, and a great screen. ICS adds snappy graphics and a laundry list of new features.


 The tiny projector (check out the pics below) will show an image up to 50 inches wide and even though the model we saw had been projecting all day, it surprisingly wasn’t too hot.

Running Android 2.1 topped out with TouchWiz, the i8520-numbered handset features a 3.7-inch Super AMOLED touchscreen.

There’s no word on battery life, which we’d imagine would be pretty poor when projecting.


You might previously have heard about the Beam under its codename, Halo. Our Samsung demo dude seemed to think we’d be getting it in Europe late in the year, possibly the Autumn.

The screen is so bright – the new Wave also has such a screen – and seeing really is believing.

However, the six lumens of brightness projection doesn’t quite live up to the billing and even in this darkened area it was hard to see the image properly.



But in concept the Beam is fantastic and we’re obviously just at the start point for pico projection phones.

It also sports a 5 megapixel camera and can record 720p video at 30fps. The phone is also capable with DivX and XviD video, so you can take your most recent download with you to watch.

There’s 16GB of memory on board and a microSD slot, too. As you can see, the model we looked at was firmly screwed down.


Samsung i8520 Beam SPECIFICATIONS: (Halo)is a mobile phones with unsightly projector add-ons or, at the very best, bulky projector housings that are seemingly slapped onto the top of the phone.The Samsung i8520 isn’t just an feature-filled Android phone, it isn’t just a projector phone, it isn’t just a smartphone with a crystal clear AMOLED display – it’s all of those things, rolled into one decently slick package.

The Samsung i8520 sports a 3.7-inch WVGA Super AMOLED touchscreen, 8-megapixel camera (720p / 30fps video recording), front-facing VGA camera, 3G data, WiFi, GPS, Bluetooth 2.1, FM radio, 3.5mm headphone jack, and of course the integrated DLP pico projector. It runs Android OS 2.1, which is awesome, but it runs Samsung’s TouchWIZ UI, which might turn some people away.

Types of Touch Screens

Touch Screen Types

Touch screens appliances are selling like a hot cake now –a – days because of its easy use and availability in various sizes. Any display device with touch screen feature sell as it comes in the market. Although people appreciate and enjoy this amazing new feature yet most of them don’t know about different types of touch screen. Different types of technologies are used in the formation of touch screen. As technology experiments are going on to derive the best devices ever so is the case with touch screen.

Different types of touch screens have different feature, characteristics and differences. These differences are resulted in different qualities of touch screen; some are long life others are sensitive while some others are economic.

Resistive Touch screen

This type of touch screen is made up of three sheets;

  • conductive
  • resistive
  • protective layer

For making the touch screen conductive and resistive layer are place together with a space between. This space allows the current to pass through it when finger press the screen. This current receive the information is then processed into the desired action. The upper layer on the glass is protection layer so that it protects the screen from scratches in case of odd resistance.

Ex : Nokia 5800

Advantages of Resistive Touch Screen

  1. It has comparatively longer life.
  2. It is used in many different ways.
  3. It is a very common type of touch screen.
  4. It is cheap and so approachable.
  5. Due to their durability, they are widely used in commercial zone.

Disadvantages of Resistive Touch Screen

  1. It emits less light as 75 % so fails to give sharp image.
  2. Its appearance is bulky.

Capacitive Touch screen

As the name describe the type of this touch screen. A thin capacitor or electronically charge sheet is placed on the glass. In response to the finger touch some of the charge from the capacitive layer shifts to the finger.
An interesting myth works over here for the functionality of touch screen. You know that capacitor works with electricity then what is the reason it responses to the human touch. Do you remember that electric shock is given to the human heart at the time of heart failure? This is because many electrons are moving in the human cells. When we touch the capacitive screen some of the charge from the screen travel towards the finger and on sheet it decreases.  This reduction in charge sheet processes the application on touch screen.

Ex: Samsung Wave or Samsung Corby

Advantages of Capactive Touch Screen

  • It emits 90% of light ray to make screen clear.
  • It has long life because of the resistivity.
  • It wont get unnecessarily  touched by ur Shirt in your Pocket.

Disadvantages of Capactive Touch Screen

  • They are sensitive only for the fingers touch no other object like stylus can be sensed.

Surface acoustic Wave Touch screen

This is the more advanced types of touch screen. They are fast and have sharp image. In this touch screen three sheets are used to perform the action;

  • Sending transducer
  • Receiving transducer
  • Reflectors layer

Both transducers are used in making of screen and these transducers enable the screen to sense the outer touch and reflectors help in giving the proper response. This whole mechanism works through the wave transmission. When we touch the screen a wave produced and transfer from one transducer to the receiver where reflectors get the message. This wave travels back to the specific place and perform the action.

Advantages of surface acoustic wave touch screen

  • Because of this wave mechanism versatile action can be done.
  • Being no electric field created, it emits 100% light resultantly quality image received.

Disadvantages of surface acoustic wave touch screen

  • They tend to have very short life.
  • They are expensive so out of reach of a common man.
  • They can be easily damaged.
