Symphony i21 specifications
|Dimensions||5.73 x 2.86 x 0.35 inch|
|SIM type||Nano SIM, Micro SIM|
The weight of Symphony i21 is about 5.08 oz with battery, which is average compared to most of the smartphones with same size. The dimensions of this Symphony smartphone are average (5.73 x 2.86 x 0.35 inch). Smaller smartphones are more compact and easier to carry around, but they may have smaller displays that can be harder to read and interact with. A Nano SIM is a small (12.3 x 8.8 x 0.67 mm) chipcard that is used in smartphones as a subscriber identity module (SIM) for connecting to a cellular network. A micro SIM is a smaller (15 x 12 x 0.76 mm) version of the standard SIM card used in mobile devices. The micro SIM card provides the same functionality as the standard SIM card, allowing the user to connect to a cellular network and use mobile data, voice, and messaging services.
|OS version||Android OS v6.0 (Marshmallow)|
|CPU||Quad-core 1.3 GHz Cortex-A7|
|Performance||AnTuTu v9: 32062|
The Symphony i21 comes with Android OS v6.0 (Marshmallow) out of the box, but it is upgradable to the next OS. Android is closely integrated with various Google services, such as Google Maps, Gmail, and Google Drive, which makes it easy for users to access and manage their data across multiple devices. The i21 has a Mediatek MT6580 CPU. This mid-range, quad-core CPU is capable of delivering fast and efficient performance for a wide range of tasks.
The i21 utilizes Mali-400 MP2 GPU. A GPU (Graphics Processing Unit) is a specialized chip that is primarily designed to handle and accelerate the processing of graphics and visual data. It is responsible for rendering images, videos, and animations on a smartphone screen. ARM Mali GPUs are widely used in mobile devices and have a good reputation for performance and power efficiency. They offer competitive performance and power efficiency, making them suitable for a range of applications, including gaming, multimedia, and user interface rendering. We use AnTuTu app to measure general processing performance. AnTuTu Benchmark is the most popular benchmark app for Android phones.
|Screen size||5 inch|
|Resolution||720 x 1280 px|
The 5 inch phone comes with IPS display. The IPS display provides enhanced features, such as optimal viewing angles, color accuracy, invariable color reproduction and better power consumption. The 5 inch display make this smartphone pocket-friendly. The size of the screen is measured diagonally, from corner to corner. A larger screen typically requires more power to illuminate, which can impact battery life. The display of Symphony i21 is multitouch capable. Multitouch technology enables the device's touchscreen to detect and interpret multiple touch points on the screen simultaneously.
|Internal storage||8 GB|
|Memory card slot||microSD|
1 GB of RAM is not typically considered to be enough for a smartphone. Most smartphones today come with at least 3 GB or 4 GB of RAM, and some high-end devices have even more. Having more RAM alone does not necessarily guarantee better performance, and other factors such as the processor and storage speed can also impact overall performance. 32 GB of internal storage is generally considered to be the minimum amount of storage you would want in a smartphone. The i21 has only 8 GB of internal storage. The internal storage of the i21 (8 GB) can be expanded with a compatible microSD card. A microSD card is a type of small, removable flash memory card used to store digital information.
|Main camera||8 MP, 3264 x 2448 px, autofocus|
|Selfie camera||5 MP|
The i21 offers only a single-camera setup. The single camera can still be sufficient for many smartphone users, depending on their photography needs and preferences. The main camera of the i21 is equipped with autofocus. An autofocus (or AF) optical system uses a sensor, a control system and a motor to focus on an automatically or manually selected point or area. Very few Android cameras come without autofocus. The i21 does not have optical image stabilization (OIS). OIS technology is more commonly found in higher-end smartphones and is designed to reduce camera shake and blur, resulting in sharper and clearer images and videos.
|GSM 2G bands||850 / 900 / 1800 / 1900|
|Network coverage||2G / 3G|
|Wi-Fi||Wi-Fi 802.11 b/g/n|
|Headphone||3.5 mm jack|
The Symphony i21 supports 2G and 3G networks only. 3G is obsolete now, because most phones can use 4G and 5G networks. The Symphony i21 like all modern smartphones, is capable of connecting to Wi-Fi networks. Wi-Fi is a wireless networking technology that allows devices to connect to the internet or other networks wirelessly, without the need for physical cables. Wi-Fi is based on the IEEE 802.11 family of standards, which define the specifications for wireless local area networks (WLANs).
With Bluetooth connectivity, you can connect your i21 smartphone to a wide range of Bluetooth-enabled devices, such as headphones, speakers, smartwatches, fitness trackers, and more. The i21 has a GPS receiver. GPS allows smartphones to determine their precise location and provide accurate navigation and mapping services. This includes turn-by-turn directions, real-time traffic updates, points of interest, and alternative routes.
The i21 isn't NFC (Near Field Communication) capable. NFC is not essential for basic phone functionality, but it can be useful for a variety of tasks and features. The i21 phone has built-in FM radio receiver. FM radio allows users to tune in to local radio stations and listen to live broadcasts, news, music, and other content. The i21 has a microUSB port. MicroUSB is a type of USB connector that was commonly used on older smartphones, tablets, and other mobile devices. The i21 smartphone has a 3.5 mm headphone jack. A 3.5 mm headphone jack is a small round port, that allows you to connect wired headphones or earphones to the device.
|Type||Li-Po 2500 mAh, non-removable|
The Li-Po 2500 mAh, non-removable battery gives the smartphone a good battery backup. The lithium polymer (Li-Po) battery is a thin, light-weight, rechargeable battery. No periodic discharge is needed and charging can be done at random. The battery of i21 isn't removable without voiding the warranty.
|Sensors||accelerometer, light, proximity|
Smartphones today come with a wealth of sensors to facilitate a better user experience. The accelerometer provides information about the smartphone's movement in three axes: X (horizontal), Y (vertical), and Z (depth). This Symphony phones come with proximity sensor. This proximity sensor detects how close the phone is to an outside object, such as your ear. The ambient light sensor detects the level of ambient light in the surrounding environment. The main purpose of a light sensor in a smartphone is to automatically adjust the brightness of the device's display. The Dual SIM capability of Symphony i21 phone is ideal for businesses wishing to provide staff with a mobile device that can offer separate numbers and bills for both personal and business use.
