The dual SIM card handsets are becoming more popular nowadays as people are leading an occupied personal and a professional life. The Samsung has introduced the new B7722 dual SIM card handset. It has a large display and it is capable of switching between the SIM cards with the touch of a button. The company would have thought that the dual SIM card feature is alone enough for the handset to compete with the other existing smartphones. It has not included an operating system in the B7722.
The B7722 has a resistive touch screen display that measures 3.2 inches. It has a resolution of 240×400 pixels and it supports 256 K colors. It has a 5 megapixel camera that supports auto focus and LED flash. It can capture images with a maximum resolution of 2592×1944 pixels and QVGA videos with a resolution of 320×240 pixels. It has an internal memory of 270 MB and also supports micro SD or micro SDHC memory cards of up to 32 GB. It has a micro USB port for charging as well as for data transfer. It has a Dolphin HTML browser with support for WAP and RSS. It supports Bluetooth 2.1 and Wi-Fi 802.11 b/g connectivity options. It uses a standard 1200 mAh lithium ion battery that can provide a life of up to 12.8 hours of talk time and up to 420 hours of stand by time.
The B7722 measures 113.5×55.5×14.3 mm in dimension and weighs around 105 grams. It is available only in black color. It has a glossy black finish that attracts finger prints and smudges. The build quality is excellent as the handset is durable and free from flex. The 3.2 inch touch screen display occupies most of the front part. This display is not very responsive as it is not capacitive. The contrast and saturation levels are normal and not very exciting. The display has a poor sunlight legibility that makes it difficult to use under direct sunlight. This is the case even when the brightness levels are maximum. There are 3 buttons below the display. The key at the middle has a edgy shape as the ones present in many of the feature phones of Samsung. It acts as the back key. The other two keys are on the either side of the middle key and they are the call and end buttons. The front facing camera is placed above the display. The other ports are found on the sides of the handset. The left side houses the micro USB port and the volume rocker while the right side houses the camera key, toggle to switch between the two SIM cards and the screen lock key.
It uses the Samsung’s proprietary TouchWIZ user interface. It has 3 home screens and a dock with 4 icons that provides access to the frequently used applications like contacts, messages, menu and keypad. It supports a number of widgets that can be placed on the home screen. The menu has icons for up to 3 pages and it includes applications like Facebook, MySpace, Google Maps, etc. These can be placed on the home screen as widgets. The interface allows the user to change the size and style of the font. The on screen keypad has large keys that are easy to press. The smart dialing option is enabled in the phonebook alone.
The contacts menu opens a scrollable list of contacts and it provides an alphabetical slider as well as a search box to find a certain contact. It cannot integrate the
Facebook contacts with the ones in the phonebook like the other smartphones form the company. Apart form SMS and MMS, the handset supports emails with an attachable file size of 5 MB. The email setup is difficult as it requires manual setting. It supports the Exchange feature and a built in document viewer. The accelerometer used is highly responsive in changing the orientation of the on screen keyboard. It has 4 rows of keys that are well spaced for easy typing. The 3G connectivity is provided by the B7722 but it can be activated by only one of the 2 SIM cards. The signal statuses of both the SIM cards are displayed but the one that is active at the time being is highlighted in green. The package includes a software CD with the Kies software that is responsible for synchronizing the handset with a computer.
The Dolphin browser renders pages slowly and has no text reflowing feature. The zooming of large web pages results in errors. The camera has a number of features and a simple interface with a variety of preset modes. The focusing is little slow. The picture quality is not very good. The images have good color and impressive details but those are spoiled by the blurry effect. The videos are captured with a frame rate of 30 fps and are of acceptable quality though they possess less detail. The built in music player supports the creation of playlists, filtering of songs, album art and equalizer presets. The handset lacks a dedicated video player. It supports videos with the MPEG4 format and stretches them to the QVGA resolution during playback. The interface of the player is simple and unresponsive. There are applications like calendar, tasks, world clock, unit converter, memo, calculator, dictionary, timer, stopwatch and voice recorder. Other necessary applications can be downloaded from the Samsung Apps menu. The handset has a feature that allows the user to set a timer to switch between the SIM cards automatically.
