Mobile phones make use of the technology which already exists but with a few innovations. The screen installed on these phones is touch-sensitive because it has a layer of a material which is capacitative as it is a tradition of the majority of the touch screens. The phone also has an electrical circuit system with all points on the grid being able to sense some changes. That means that some signals are produced by every point on the grid. These are then relayed to the processor of the phone.

Even if you make simultaneous touches on the screen, the touch screen is capable if identifying where they were made.

The type of material used in making these phones only responds to touch by the fingers. That means that if you put on gloves the touch screen will not work.

Methods of Detecting touch

The screen of an iPhone has two ways of detecting touch.

• Mutual capacitance: In this case, two layers of capacitive circuitry is needed. The first layer is responsible for holding driving lines which passing current along. The other layer consists of sensing lines. These lines are capable of detecting current at the various nodes.
• Self capacitance: This way of detecting touch makes use of a layer of separate electrodes which are connected with a network of circuits capable of sensing touch.

 

The two methods mentioned above are responsible for sending electrical impulses to the processor. This is what we are going to look at. We will see how it works in these articles. At this point, it should be emphasized that the software is very important to interpret the input on the touch screen.  The kind of data sent to other processor is raw data which needs to be interpreted. From the touchscreen to the processor, the signals move in terms of electrical impulses.

The features of every touch are analyzed by the software in the processor. This way data is converted into useful information. The processor has a way of arranging the touches into groups depending on the features. When you move your fingers, the processor determines the starting and finishing point.

The gesture interpretation software is used to find out which command you sent. Your physical movement is combined with the information on which the application is made for. This is followed by the program sending the instructions to the right program. When the raw data does not match any available command, the touch-screen ignores such touch as one made by mistake.

All the above mentioned processes take place in an instant. The changes you see on the screen are all based on your input. With this process you will access all the features of the phone just by touching the screen using your fingertips.

The screen shape changes according to your taste and preferences. The screen can be shifted into many styles such as horizontal, vertical and even tilting it. There is an accelerator in the smartphones which helps the phone to change the orientation of the screen. That is, you can scroll through long lists of music files on a narrow or long screen and then be able to watch your favorite movies in a widescreen format.

Everybody loves the Samsung Galaxy S3. It’s been released to critical acclaim everywhere, topping critics’ charts of the best phones of 2012, and it’s without a doubt a going to be the best-selling Android handset of the year. It’s easy enough to write a long review extolling the virtues of such an unearthly handset, but that’s a little drab and dull – so, instead, we’re going to count the top 10 reasons for getting your hands on a Galaxy S3. If you don’t already have your eye on one of these smooth, sleek handsets, then you certainly will after reading this list. Then all you’ve gotta do is convince a generous benefactor to treat you to one.

 

Quad-Core Power

 

If you use your phone enough to want to spend £500 on a new one, chances are the quad-core processor packed into the Samsung Galaxy S3 will make your life a lot easier. It’s handy for any moderate to heavy smartphone users who don’t want to spend their time waiting for apps, web pages and games to load up. It also means you can multi-task easily on the S3, so if you like to listen to music while browsing the web and playing apps interchangeably, you’ll really like the S3.

 

Smooth Design

 

The Samsung Galaxy S3 has ditched the squared-off corners of the S2 and instead opted for a more rounded look. It’s surprising how much smoother and sleeker this makes the phone appear. It’s not a small handset, with a 4.8-inch display smack-bang in the middle of it, but somehow Samsung managed to streamline it to 8.6mm in depth and just 133g in weight. If that’s not great design, we don’t know what is.

 

Intuitive Gestures

 

The gesture set for the Samsung Galaxy S3 has been vastly improved since the S2, and if you like your phones usable, you’ll be very happy with the S3. Smart Stay is a feature which tracks your eyes using the front-facing camera; once the phone senses you’re looking away from the display, it’ll dim the screen and switch off. If you often forget to set your phone to silent when entering meetings, you’ll also like Turnover. If your phone rings in class or during a meeting, you simply turn it over to immediately silence it.

 

Snappy Snapper

 

The Samsung Galaxy S3 boasts two cameras; one round the back and one round the front. The front snapper is a 1.9MP camera, which will do you fine when it comes to video-calling and Skyping, and also comes in handy if you desperately need a new Facebook profile pic. The rear-facing snapper is an 8MP camera – the same as HTC’s offering in the One X – but is also comes with some great software, so taking photos on your Galaxy S3 doesn’t have to be a chore. The resultant pics look smooth, crisp and clean.

 

50GB of DropBox Storage

 

It’s not unusual to find DropBox storage offered by high-end phone manufacturers these days; HTC offer 25GB of DropBox Storage with many of their phones, while Apple offered 5GB with the iPhone 4S. Samsung, however, have outdone the competition with their offering of 50GB of DropBox storage to owners of the S3. DropBox storage is cloud storage, so when you save data – movies, music, etc. – they don’t have to go somewhere physical on your phone. It’s cool, convenient and compact.

 

Excellent Display

 

The Samsung Galaxy S3′s fantastic display is a Super AMOLED HD display, with a resolution of 1280 x 720 pixels, making it one of the best displays you’ll see on any smartphone on the market at present. It’s 4.8-inches, as already stated, so if you like to read text or e-books on your phone, the S3 will definitely appeal to you. The S3′s display is big, bright and bold, and makes everything you view on the phone just a little bit more enjoyable when compared to using a ‘regular’ smartphone.

 

Reasonable Battery Life

 

OK, so the battery life of very few smartphones deserves to be called ‘good’, but Samsung have done very well in giving the S3 a pretty decent battery life compared to other high-power handsets. The S3′s 2100mAh battery is a mammoth of its kind; it means that if you use your phone for web browsing and video streaming throughout the day, you won’t have to worry about the S3 not lasting until evening.

 

Android 4.0 and Beyond

 

The Samsung Galaxy S3 comes with Android 4.0, Ice Cream Sandwich. This is the latest version of Android, and it features some of the biggest improvements to be made to the OS since its inception. However, that’s not all; as Android’s flagship smartphone, you can feel fairly safe in the knowledge that future versions – such as Jelly Bean – are going to be rolled out to the S3 pretty sharply, because Android need to all they can to keep their top handset, well, at the top.

 

Download ALL the Apps

 

If you love apps, you’ll love the fact that the high-tech spec of the Samsung Galaxy S3 means that you’ll never find an app you can’t use. The S3 packs in everything you need to play the most intense, complex, 3D games and apps available on the Android Marketplace, and you can rest assured that it’ll doubtless also handle any apps that are released in the next couple of years.

 

Longevity

 

This one might not appeal to you if you’re a major tech geek – you know, the kind that wants the latest gadgets the moment they’re release. In other words, if you’re going to buy the iPhone 5 – or whatever’s big next year – as soon as it’s released, then you’re not going to be bothered by this. However, if you’re looking for a handset that won’t look terribly dated in a year’s time, consider the S3. The technology and the design in this phone is so swish, we’ll wager it’s going to still look contemporary in a couple of years – if you can avoid breaking it, this baby will keep ticking over nicely for some time yet.
