The Samsung Comment 2 R390C is a feature phone that was announced and released in October 2012. Known for its compact design and practical usability, this phone was specifically aimed at users who preferred QWERTY keyboards over touchscreens. Although discontinued, the phone has been recognized for its simplicity and efficiency during its availability period.
The Samsung Comment 2 R390C operates on CDMA technology, supporting CDMA 850/1700/1900/2100 bands. This means that it was compatible with certain carriers that used CDMA networks. Notably, the phone does not support GPRS or EDGE technology, which are commonly used for mobile data, pointing towards its design being optimized for basic call and text functions rather than internet usage. Bluetooth 2.1 with A2DP support is included for wireless connectivity, but there is no WLAN, positioning services, NFC, or radio capabilities.
The phone measures 110 x 61 x 10.9 mm and weighs 95 grams, making it portable and easy to handle. The form factor features a QWERTY keyboard which appeals to those who favor physical keys for typing. In terms of display, it carries a 2.4-inch screen with a resolution of 320 x 240 pixels and a pixel density of approximately 167 ppi. The TFT display supports 256K colors, which provides basic visual quality for general use.
Internally, the Samsung Comment 2 R390C comes with 256MB of storage, which is relatively small compared to modern smartphones. However, it does include a dedicated slot for microSDHC cards, allowing users to expand storage for media and additional contacts. The phonebook capacity allows up to 1000 entries, and photocall functionality supports image-associated contacts. Call records can also be stored, which is a useful feature for managing communications.
Equipped with a single 2 MP main camera, the Samsung Comment 2 R390C offers basic photography capabilities. Video recording is supported at a resolution of 176x144 pixels. While it may not suffice for high-quality imaging demands, it is adequate for casual snapshots and small-scale video capturing.
Audio capabilities include a loudspeaker for hands-free calling and multimedia playback, along with a 3.5mm headphone jack for connecting external audio devices such as earphones or speakers. The presence of a standard audio jack is a convenient feature for users who utilize wired headsets.
The phone supports SMS, MMS, Email, and IM messaging, catering to the basic communication needs of users. There are pre-installed games available for entertainment. However, it does not support Java, which limits the installation of additional applications beyond what is provided by default.
A removable Li-Ion 1000 mAh battery powers the Samsung Comment 2 R390C. It offers up to 264 hours of standby time and approximately 4 hours of talk time, which, for a feature phone with limited functionalities, translates into a satisfactory battery life. The option to replace the battery is an advantage for users looking to maximize the longevity of their device.
The phone was initially offered in black and was priced around 60 EUR, making it an affordable choice for users seeking a no-frills mobile phone. Its SAR values were recorded as 0.97 W/kg for the head and 1.07 W/kg for the body, which are within standard safety limits for mobile devices.
In summary, the Samsung Comment 2 R390C represents a practical and user-friendly mobile solution from its time, aimed at consumers who prioritize basic communication and ease of use over advanced smartphone features. It offers essential functionalities in a compact and straightforward package, appealing to a specific segment of mobile users.
