The Amoi CMA8170, launched in 2007, is a feature phone that reflects a particular era in mobile technology, characterized by simple yet practical functionalities suitable for basic communication needs. Despite being discontinued, the device offers a glimpse into the pre-smartphone era where efficiency and battery life were prioritized over multimedia capabilities.
The Amoi CMA8170 is equipped with GSM technology, supporting GSM 900 and 1800 bands alongside CDMA2000 1x EV-DO. However, it lacks more advanced data transmission technologies such as GPRS and EDGE, marking its primary use for voice calls and basic messaging. The phone does not support WLAN, and its Bluetooth version 1.1 allows for limited wireless connectivity, suitable more for simple tasks like sending contacts or small files. The absence of a positioning system (such as GPS) and non-functional USB connectivity further underscore its role as a basic communication tool.
In terms of design, the Amoi CMA8170 has a compact body with dimensions of 92.5 x 49.5 x 18.7 mm. Its usability is enhanced by its lightweight, though the exact weight is unspecified. The device accommodates a Mini-SIM, reflecting its era's standard. The display is a modest 2.0-inch TFT screen, capable of showing 256K colors. With a resolution of 176 x 220 pixels, this display is functional for browsing through menus and conducting basic operations, standing at a screen-to-body ratio of approximately 27.5%.
The phone offers an internal memory of 90MB, which is quite limited by today's standards but was typical for feature phones in the mid-2000s. Thankfully, it includes a dedicated microSD slot for memory expansion, allowing users to store more contacts, messages, and possibly a few media files. The Amoi CMA8170’s phonebook can store up to 500 entries, with records of the last 20 dialed, received, and missed calls, which was adequate for its intended market.
Equipped with a single 1.3 MP main camera, the Amoi CMA8170's photographic abilities are limited. Given the phone's constraints, users could expect functional photos sufficient for casual photography to capture basic moments but without sophisticated image clarity. Video recording capability is absent, which aligns with the phone's focus on simplicity and primary utility.
The Amoi CMA8170 is designed without a loudspeaker and does not support a 3.5mm audio jack, restricting music and audio playback options. The alert types supported include vibration and downloadable ringtones in polyphonic, MIDI, and MP3 formats, thus providing basic personalization criteria for notifications. The lack of a loudspeaker reinforces its focus on straightforward communication rather than media consumption.
Powering the device is a removable Li-Ion 860 mAh battery, which facilitates decent battery performance given the phone's limited power demands. Such a battery capacity suffices for extended standby and talk times, advantageous in an era when recharging was often less frequent. The removable nature of the battery also adds to the longevity and repairability of the phone.
The Amoi CMA8170 includes basic messaging options like SMS, MMS, and Email, integrating essential communication methods available at the time. The presence of WAP 2.0 browser hints at rudimentary internet browsing capabilities, subject to network limitations. Java support is optionally provided, opening avenues for running Java-based applications and simple games, enhancing entertainment options despite the phone's core simplicity.
Announced in 2007, the Amoi CMA8170 has since been discontinued, which was the fate of many feature phones as smartphones rose in dominance. Its availability now is likely confined to second-hand markets or as a collector's piece, reflecting the technological landscape of the late 2000s.
While modern expectations for mobile devices far surpass what the Amoi CMA8170 offers, it serves as a testament to the era when feature phones met the primary needs of mobile communication. Its specifications, while modest, cater to a no-frills, reliable communication experience, which some users might still appreciate for its simplicity and focus on fundamental phone functionalities.
