The success of iPhone and Android has made touch screen mobiles extremely popular. Companies have launched touch screen phones at every price range to take advantage of this popularity. These mobiles differ significantly in quality and responsiveness. Unfortunately many people make the mistake of thinking that any touch screen mobile will be good enough and then end up with a bitter experience.
In this article we shall look at some of the important criteria to consider while buying a touch screen mobile and how to find one that meets your requirements.
Capacitive or Resistive:
These are two distinct technologies used by touch screen phones. The resistive technology senses the pressure to identify the touch whereas the capacitive touch screens use electrodes to sense the touch of your finger. The resistive touch screens are less responsive and typically require a stylus to work. Even among the capacitive touch screens, the responsiveness and accuracy vary widely. The responsive phones come with a higher price tag but a touch screen that is not responsive enough will make the experience an irritating one.
Type of display:
If Retina Display, Super Amoled and S LCD, sound like some language other than English to you, then do not worry. Most users get confused by this technical marketing terms. Broadly speaking these are the different types of screen that power the high-end touch screen phones.
The retina display is used in iPhone 4, so named because the pixels cannot be identified by human eye, which results in a sharp and brilliant display. AMOLED stands for Active-Matrix Organic Light-Emitting Diode. The Nokia N8 runs on Amoled screen while a few Samsung Touch Screen Mobiles like the Samsung Galaxy S I9000 supports a super AMOLED screen.

Availability of QWERTY:
Playing games on a touch screen phone is definitely cool but typing on the touch screen can be a problem for anyone. Especially if you have long nails and you intend to do a considerable amount of typing then you should go for a touch screen phone that has a QWERTY keyboard as well.
Touch screens drain battery a lot faster than any other type of mobile. So while comparing touch screen mobiles, give extra consideration to the battery life.
Screen Size and Resolution:
Too small a screen reduces the usability of the mobile considerably while too large a screen will make the mobile bulky. The screen sizes vary between 2.5 inch and 4 inch. A screen size in the middle like 3.2 inch is the ideal solution. However consider the primary use of the mobile while deciding on a screen size ideal for you. For example if you intend to watch movies on your mobile then the 4 inch screen size may be the best for you.
Finally you will do well to remember that just because a mobile has a touch screen, the other functions do not become unimportant. You must consider other aspects like connectivity options, the processor and RAM before making the final choice.
