Nothing special about the design, looks ordinary. Not much different kind of mobile-phone qwerty. But nice solid design plan, with a casing material that is also quite good. There are several buttons and slots on the side of the phone including memory card slots and ports for audio jacks.
With the qwerty design, of course, the concept of the screen is horizontal. Can display images bright enough and with the full screen mode, but it depends also from the file photo or video. Screen size 38 x 50 mm is comfortable enough to display some multimedia features, including when browsing the Internet.
No visible number that indicates the strength of the resolution which is usually written on the side of the lens. But, after we test image settings settings, the camera is capable encouraged ZTE GC990 at a maximum resolution of 1280 x 1024 pixels aka 1.3 Mpix. And, when tested the picture on the computer, the size of the true size of the resolution. The resulting image less than the maximum, let alone minus the flash light and other optimization. However, when light conditions are adequate, the result is quite good.
When tested with multiple audio formats, like MP3, AAC, and WAV, these applications can run well. Well, the sound quality, sounded flat, not equipped with an audio equalizer or another booster. However, when lauched until maximum volume, sound from the speakers are not broken.
As usual, to activate the FM radio feature, we have to plug in the headset first. Simplicity is that we can use a headset with 3.5 mm universal jack. This means that this phone can be compatible with a common headset. Existing radio feature seems simple, and no additional features or track record broadcast ID.
GC990 ZTE relies on two kinds of connectivity for data traffic and connect with other devices, the mini USB cable and bluetooth. USB ports have a common standard, when we tested with the same interface with other phones miniUSB cable is compatible, there are no constraints. Bluetooth has a fairly complete profile, such as handsfree, headset, A2DP, FTP, HID, and DUN.
Overall this phone works well. For the record when taking pictures, saving process takes a few seconds. Thus, we must be ready hand position until the saving process is completed so that images do not blur.
General constraints on dual phone on the need of battery consumption doubled compared with single-band phones. Moreover, if the active use of multimedia features, will more quickly drain the battery. During the test period with a capacity of 900 mAh battery can last up to two days.
