Manufacturers of mobile devices today is almost universally rejected the use of a large number of hardware buttons (on the device) and stylus, allowing them to provide inexpensive cheap phones replacing them with touch control. Nevertheless, the market there are trade-offs when the touchscreen is complemented by a physical QWERTY-keyboard (such as HTC Touch Pro 2). Form factor of such phones is called 'side-slider' conventional sliders and candy bars with small buttons under the display had gone into the past. To facilitate the management of screens in such devices are equipped with the support of not only single touches, but at the same time in touch multiple locations (multi). This is true, for example, to scale the photos or web pages. However, for the proper functioning of the multi-touch screen should be performed on a capacitive technology, and not be resistive. This imposes restrictions on its use, for example, in the cold or gloved fingers with long nails. Diagonal screen sizes are still relatively important criterion for selecting the unit, but it must be with the physical resolution, which he supports.
The wide format with a huge resolution (WVGA, for example, like HTC HD2) displays can be just fine for viewing video or photos, but not come for the games. Factories, in principle, have learned to put the display to a comfortable viewing content in the 3-3.5 inch inches is not much housing. All displays are installed on Chinese touchscreen phones are not as large size, are a sign not expensive phone – they can be useful only in the classic scenario of the device. As communicators today, as before, use a memory card standard microSD, but no such small capacity (high capacity) – they put up to 32 GB of information. Whatever it was, not all devices support such drives correctly – it comes from the 8 or 16 GB (on card or do not read, or read errors), so better to have a few cards or in advance, before you buy the phone checks the keeper of information. As an interface connector for wired connections are commonly used mini-micro USB inputs.
They allow you to charge your phone through the normal cable which cost less than $ 100 (as opposed to not cheap reel stands) during synchronization with a PC or a mode card reader or USB drive. Stereo headset plugged into a standard 3.5 mm output – have a proprietary input is currently not allowed. Communicator – a device in the first place for the operation of the web. This suggests that it must have high-speed wireless connection and to it is desirable to be expensive and not cheap to buy a phone you can not everywhere. These include 3G and Wi-Fi. If the latter – is already known technology (in the last few years for it to add on support for specification of WLAN IEEE 802.11n, protocol encoding WPA2 and implementation of DLNA to connect wirelessly multimedia equipment), the 3G network is still relatively new to used to the GPRS EDGE connection users. Ideally, a device must support nynushnee add HSDPA, allowing it to download information from the Internet twice as fast as 'normal' UMTS – at speeds up to 7.2 Mbit / sec. WiMAX devices and CDMA smartphones are for domestic buyers are not usually not the usual thing (they sold them to buy and use such communication services, but to speak of the widespread of such equipment can not).
For WM-units have traditionally been considered the defining corporate functions (e-mail, edit office documents, Web-browsing, etc.), though nothing prevents you from using them quite serious opportunities for entertainment (watching videos, games). Manufacturers typically rely on an extended model of user interaction by setting such a great communicator screens (2.8 "and above) and the QWERTY-keyboard whereas in this category to meet the usual number pad for dialing difficult. On the performance of these devices (size, weight, autonomy) influence on the one hand, the desire to equip them maximum, and with another – the need for a powerful enough processor to cope with resource-intensive operating system. Note that the already announced an enhanced version of Windows Mobile 6.5, has a number of interesting innovations, which intended to provide a competitive advantage in the fight against rookie Android from Google. But some devices described above: ASUS P535 This piece differs decent functionality (Bluetooth 2.0 + EDR, Wi-Fi, GPS, camera 2 megapixel with autofocus) and good performance (520 MHz XScale processor, 256MB Flash ROM). Integrated GPS-SiRF Star III chip provides excellent sensitivity – an important quality in an urban navigation. In addition, the ASUS P535 are cheaper competitors that gives us the right to recommend it As a best buy. ASUS P565 communicator with a record performance in its class able to cope well with a wide range of tasks from viewing high-definition video and ending with holding intensive calculations.
In addition, he has the support networks of 3G, GPS and a full set of wireless interfaces for data transfer. HTC Touch Select this compact and stylish model will be able to almost completely rid you of need to use the stylus to control the mobile terminal. The implementation of this approach is worthy of respect and the best recommendation for demanding users to ergonomics. And for fans note the presence of beauty in selling as much as three colors: black, green and white.
All the leading manufacturers in the mobile phone market have focused on the production of feature phones (smartphones). Samsung is no stranger to this area, customers are already familiar with previous models of this Series: Samsung SGH-i750 and Samsung i320. The completion of this series was Samsung SGH-i600. Models i320 and i600 are similar in design, slim and QWERTY-keyboard. But apart from that a beginner has some advantages over the predecessor: it's Wi-Fi and support for UMTS.
Appearance Smartphone is not overloaded with design tricks and trends of the flow of the glamorous and not touched. Design is fully consistent business-style black plastic, austere design. Form buttons slightly unusual, they made a sort of "wave", but after a brief adaptation begin to feel the charm of a complete layout. Many of the new Samsung seem broad and uncomfortable, but it compensates for the large size soft-touch coating Soft Touch. The use of "gentle" coating in the production of mobile phones – an innovative move, which immediately received the endorsement in the face of consumers. Another plus is the phone's 2.3-inch display.
TFT-matrix with a resolution of 320×240 pixels, located in a horizontal orientation and supports 65k colors, but it provides outstanding color reproduction and stunning color depth. Viewing angle is not very big, but it's not a problem, since unlikely you will need to look at the phone's screen at an angle of 160-180 degrees. Among the options screen is a 5-level brightness control, choice of color scheme, layout firewall. 1.3 – megapixel camera, unfortunately, has not the highest image quality and the lack of autofocus, too sad. But here is the quality of video footage is at a height. On the phone was originally a pre-installed the necessary software: Picsel Viewer and Windows Media Player and such necessary wireless connections like Bluetooth and Wi-Fi. Confuses the novelty of its slow speed and launch applications, low quality images and larger sizes. However, it is worth noting excellent communication capabilities, light weight and longer working. Smartphone, based at the operating system Windows Mobile 5.0., Has good ergonomics and practicality.
