Control: voice dialing, voice control Sensors: proximity Flight mode: yes Touch screen: There are two types of touch displays: resistive and capacitive.Resistive displays consist of two transparent plates that make electrical contact with each other at the point of pressure. Such displays respond to mechanical force by means of any object. Devices equipped with such displays are equipped with special sticks - styluses, which are convenient to control the device.
The disadvantage of such a display is the high susceptibility of the screen to scratches and abrasions, when you control your fingers, you need to make an effort to react the device.
The second type of touch displays - capacitive, devoid of these shortcomings, because. were originally developed for direct finger control, without the use of any third-party items and tools.
In each corner of the display are electrodes that apply the same alternating voltage to the conductive layer of the display. When touched with a finger or other object capable of conducting current and having its own electrical capacitance, current leakage occurs. The closer the touch point is to the electrode, the lower will be the electrical resistance of the display and, accordingly, the current strength will be greater.
Devices with such displays react exclusively to hand control, touching the surface of other objects, due to the lack of their own electrical capacitance, will not lead to the closing of the “contact point - electrode” circuit, and will not have any effect on the device. With the possibility of customization, such a display can be configured not even to touch with a finger, but only to bring it to the surface.
The indisputable advantage of such displays is their very high resistance to mechanical damage, in view of the possibility of using sufficiently thick and durable surface glasses.
Another advantage is the very high accuracy of touch coordinates, up to one pixel. When controlling the hand, of course, such accuracy turns out to be unclaimed, but when using special conductive styluses, it opens up great potentialities.
Capacitive displays are more transparent (about 90%) than resistive ones, the transparency of which does not exceed 85%, which makes it possible to display a better picture on their surface.
The physical resource of capacitive displays is at least 200 million clicks, which corresponds approximately to 6.5 years of clicks with an interval of 1 second. Contamination of the surface with non-conductive substances does not affect their operation.
The relative disadvantages of capacitive touch displays are the need to use large displays in mobile devices due to the need to provide comfortable hand control and higher cost compared to resistive ones.

General characteristics
Type of
Deciding on the type of device (phone or smartphone?) is quite simple. If you need a simple and inexpensive device for calls and SMS, it is recommended to stop the choice on the phone. A smartphone is more expensive, but it offers a wide variety of options: games, videos, the Internet, thousands of programs for all occasions. However, its battery life is significantly less than that of a regular phone.
