Specifications
Design
The design of the Starmobile Diamond X1 features two distinct color variants, utilizing a polished metal frame, rounded corners, and a 2mm thin side bezel. One configuration pairs a black front panel with a white accents and a removable brushed aluminum rear cover, while the alternative version presents a uniform two-tone black finish paired with a matte metallic back panel. The front of the phone hosts three capacitive navigation buttons alongside sensors and the camera. Physical controls include a power button and a headset jack sitting at the top frame, with a dedicated volume rocker placed on the right side and a microUSB interface sitting at the bottom boundary.[1]
Hardware
The device is powered by a MediaTek MT6592 system-on-chip that features a 1.7 GHz octa-core processor alongside a Mali-450MP4 graphics processing unit.[3]
It comes built with 2 GB of RAM and 8 GB of internal flash storage, which can be expanded by up to an additional 64 GB via a dedicated microSD card slot.[4] It relies on a removable 2,400 mAh lithium-ion battery, which provides roughly 6 hours of local video playback under testing conditions.
Audio
Unlike many contemporary smartphones that utilize generic loudspeakers, the Starmobile Diamond X1 features an audio system engineered by Yamaha, a Japanese manufacturer of audio equipment and musical instruments.[5]
Display
The phablet is equipped with a large 6.0-inch IPS LCD panel sporting a High Definition resolution of 1280×720 pixels.
Cameras
The smartphone utilizes an 18-megapixel backside-illuminated (BSI) sensor complete with autofocus tracking and a single LED flash. The default camera application includes several specialized shooting presets such as High Dynamic Range (HDR) exposure, smile detection, multi-angle stitching, and built-in image filters. Video recording with the rear setup captures up to 720p resolution footage at a fluid 30 frames per second saved into a 3GP file format container. Facing forward, an 8-megapixel BSI sensor handles selfie photography and basic mobile video calling tasks.[6]
Software
The handset ships out of the box running the Android 4.2.2 Jelly Bean mobile operating system natively. Starmobile layers a lightweight proprietary custom user interface on top of the base Android platform to keep animations and navigation transitions highly responsive. To minimize software bloat, third-party system applications are kept to a minimum, though it does feature select factory pre-loaded tools such as the Starmobile App Store and Starmobile Sync utilities alongside core social networking apps.
