The LG KF311 was introduced to the market as a versatile feature phone that combined essential mobile functionalities and moderate multimedia features. Released in February 2009, the device was part of the mid-range segment, serving users who required basic connectivity, communication, and media capabilities without the complexities of modern smartphones.
The LG KF311 boasts a compact form factor with dimensions of 94 x 47 x 16.8 mm and a weight of just 95 grams. This makes it perfectly pocket-sized, emphasizing portability and ease of handling. The phone's design, while functional, is reflective of the minimalistic approach typical of its era. It incorporates a Mini-SIM slot, further simplifying its basic structure.
The device features a 2.0-inch TFT display capable of showing up to 256K colors. Despite its small size, which takes up approximately 28.5% of the body, the display offers a resolution of 176 x 220 pixels, delivering a pixel density of about 141 ppi. This ensures the display is clear enough for basic tasks and moderate image viewing.
On the photography front, the LG KF311 includes a single 2MP rear camera. While it lacks the sophisticated imaging capabilities of modern devices, it still provides users with the ability to capture everyday moments. Additionally, the phone supports video recording, albeit at basic levels. Another highlight is the VGA front-facing camera, which supports video calls, a notable feature given the phone's release date.
The device comes equipped with 45MB of internal storage, a figure that is modest by today's standards but was sufficient for its target audience at the time. To complement this, the KF311 features a microSD slot, allowing users to expand their storage capacity and better manage their files, contacts, and multimedia content. The phone's phonebook can store up to 500 entries, with options for photocall, making it practical for users needing to maintain multiple contacts.
Network capability is a key aspect of the LG KF311, featuring GSM and UMTS technologies. It supports 2G bands (GSM 850, 1800, 1900) and 3G bands (UMTS 2100), ensuring decent connectivity in various regions. Users can achieve network speeds of up to 384 kbps, which was typical at the time for efficient mobile browsing.
While the phone does not support WLAN or positioning services, it does include Bluetooth version 1.2 and USB 2.0 connectivity, enabling basic device pairing and data transfer. Messaging is a strong point, with support for SMS, EMS, MMS, and email. A built-in WAP 2.0/xHTML browser offers limited internet browsing. The phone supports Java (MIDP 2.0) for basic applications and games, enriching the user's interaction with the device.
The LG KF311 is equipped with a loudspeaker, though it lacks a 3.5mm audio jack, which limits headset connectivity without specific adapters. The phone does not include a radio feature, focusing instead on stored audio files and available streaming options with compatible applications via Bluetooth or USB.
Powered by a removable Li-Ion 900 mAh battery, the LG KF311 offers adequate battery life suitable for its features and use case scenarios. It provides up to 443 hours of standby time and approximately 5 hours and 36 minutes of talk time, ensuring it meets the everyday needs of users who require a reliable device with sufficient longevity.
The LG KF311 serves as a testament to the feature phone era, delivering basic functionalities in a compact, user-friendly design. Though it may not compete with modern devices in terms of features or power, it provides a respectable mix of communication, multimedia, and connectivity options for its time. Discontinued now, it remains a piece of mobile technology history that illustrates the evolution of mobile devices over the years.
