The Samsung Continuum I400, launched in November 2010, showcases a design that blends functionality with a sleek aesthetic. Weighing just 125 g and measuring 125 x 58 x 12 mm, its compact form factor makes it comfortable to hold and easy to carry. The device features a stylish black exterior, complemented by Corning Gorilla Glass that provides durability against scratches and impacts. Despite being discontinued, the Continuum’s form factor remains a representation of the trends prevalent in smartphones during its release.
The smartphone is equipped with a 3.4-inch Super AMOLED display, offering vibrant colors and deep contrasts. With a resolution of 480 x 800 pixels and a density of approximately 274 ppi, users can enjoy clear and sharp visuals. Notably, the Continuum features a unique secondary display known as the 'ticker display.’ This innovative addition provided quick access to notifications, time, and other essential information without having to activate the main display, conserving battery life.
Under the hood, the Samsung Continuum I400 is powered by a Hummingbird chipset paired with a 1.0 GHz Cortex-A8 CPU and a PowerVR SGX540 GPU. Although modest by today's standards, at its launch, these specifications provided adequate performance for typical smartphone tasks. The device originally ran on Android 2.1 Eclair and was upgradable to Android 2.2 Froyo, ensuring access to improved features and applications. The setup allowed for a reasonable multitasking experience despite its 336 MB of RAM.
Photography on the Samsung Continuum I400 is facilitated by a 5 MP rear camera featuring autofocus and an LED flash, allowing for decent quality photographs under well-lit conditions. Capable of recording 720p video, the camera supported casual photography needs. However, the absence of a front-facing camera reflects the era's limitations, when selfies and video calls were not as prevalent.
The device operates on CDMA/EVDO networks, supporting CDMA bands 800/1900 and CDMA2000 1xEV-DO for 3G connectivity with speeds up to 3.1 Mbps. Wireless connectivity options include Wi-Fi 802.11 b/g/n with DLNA and hotspot capabilities (available from Android 2.2 onwards), Bluetooth 3.0 with A2DP, and microUSB 2.0 for data transfer. The inclusion of GPS and A-GPS ensures basic geolocation services. Notably, FM radio support is absent, which might be a drawback for radio enthusiasts.
The Samsung Continuum offers 2 GB of internal storage coupled with 336 MB RAM, reflective of storage standards from that period. For users in need of more space, a dedicated microSDHC slot is available, with an 8 GB card included, providing additional room for media and applications. Given the era's reliance more on local storage than cloud solutions, this setup sufficed for basic usage needs.
Powering the Continuum is a removable Li-Ion battery, providing a stand-by time of up to 312 hours and a talk time of up to 7 hours. This level of battery life was considered satisfactory, enabling moderate usage throughout the day. The ability to replace the battery was a significant advantage, allowing users to carry spare batteries as backup, a feature less common in modern smartphones.
This device is equipped with key sensors that enhance its overall utility, including an accelerometer, gyro, proximity sensor, and compass, enabling better user interaction and navigation. However, limitations such as the absence of a front camera and FM radio are notable. Its 3.5mm headphone jack ensures compatibility with a wide range of audio devices, maintaining a standard that has since become less common in newer devices.
The Samsung Continuum I400 represents an interesting chapter in smartphone evolution, balancing innovation and practicality. Its dual-display design predated the always-on displays of today, offering a glimpse into future trends. Despite being discontinued and superseded by more advanced technology, the Continuum's legacy as a bridge between traditional and modern smartphone designs remains apparent among tech enthusiasts and industry observers.
