Walton Primo EM specifications

Body

The weight of Walton Primo EM is about 4.66 oz with battery, which is average compared to most of the smartphones with same size. The dimensions of this Walton smartphone are average (4.96 x 2.52 x 0.41 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 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.

System

The Walton Primo EM comes with Android OS v4.4.2 (KitKat) out of the box, but it is upgradable to the next OS. Android is based on the Linux kernel and includes a user interface, middleware, and a range of pre-installed applications. The Primo EM has a Spreadtrum SC7731G CPU. This mid-range, quad-core CPU is capable of delivering fast and efficient performance for a wide range of tasks. The Primo EM 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.

Display

The 4 inch phone comes with TFT display. A thin-film transistor (TFT) is a type of field-effect transistor that is usually used in a liquid crystal display (LCD). This type of display features a thin-film transistor for each individual pixel. In recent years, many smartphone manufacturers have moved towards using other display technologies, such as OLED and AMOLED, which offer some advantages over TFT.

Smaller smartphones are generally more compact and easier to handle. 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 Walton Primo EM is multitouch capable. Multitouch technology enables the device's touchscreen to detect and interpret multiple touch points on the screen simultaneously.

Memory

512 MB 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. The amount of RAM needed for optimal performance depends on factors such as the operating system, the apps and services you use, and how you use your device. 32 GB of internal storage is generally considered to be the minimum amount of storage you would want in a smartphone. The Primo EM has only 4 GB of internal storage. The internal storage of the Primo EM (4 GB) can be expanded with a compatible microSD card. MicroSD cards are popular because they're small, lightweight, and easy to use.

Camera

The Primo EM 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 camera of the Primo EM has no autofocus capability (fixed-focus). 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. Primo EM is equipped with a basic camera setup, and it does not have any advanced features. Basic camera setups are designed to fulfill the needs of users who prioritize affordability and basic photography requirements.

Connectivity

The Walton Primo EM like all modern smartphones, is capable of connecting to Wi-Fi networks. Wi-Fi networks use radio waves to transmit data between devices and a wireless access point, which is typically connected to a wired network and serves as a hub for wireless devices to connect to the internet or other networks. The Primo EM supports the latest Bluetooth standards, which offers faster data transfer speeds, better range, and improved reliability compared to previous versions of Bluetooth.

The Primo EM 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 Primo EM 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 Primo EM phone has built-in FM radio. During emergencies or natural disasters when cellular networks may be congested or disrupted, FM radio can provide a reliable source of information and emergency alerts. The Primo EM has a microUSB port. MicroUSB is a type of USB connector that was commonly used on older smartphones, tablets, and other mobile devices. The Primo EM 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.

Battery

The Li-Po 3000 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 Primo EM isn't removable without voiding the warranty.

Features

Smartphones today come with a wealth of sensors to facilitate a better user experience. The Walton Primo EM smartphone has an accelerometer. The presence of an accelerometer in smartphones enables a range of interactive and intuitive functionalities that enhance the user experience and enable innovative applications. This Walton 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 Walton Primo EM 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.
