Walton Primo EF3 specifications

Body

The weight of the Walton Primo EF3 is 5.82 oz. It is still considered to be relatively lightweight and portable. The dimensions of this Walton smartphone are average (5.59 x 2.86 x 0.37 inch). For some people, larger smartphones are more comfortable to hold and easier to use, as they provide a larger display for watching videos, browsing the web, and using apps. A micro SIM is larger than the current standard Nano SIM card but smaller than the older, larger SIM card size. You can use a SIM card adapter to convert a Micro or Nano SIM card into the required size.

System

The Walton Primo EF3 comes with Android OS v4.4.2 (KitKat) out of the box, but it is upgradable to the next OS. Android is an open-source operating system, which means that the source code is freely available to the public and can be modified and distributed by anyone. The Primo EF3 has a Spreadtrum SC7731G CPU. A quad-core mobile CPU can provide fast and efficient performance for mobile games. The Walton Primo EF3 comes with Mali-400 MP2 Graphics Processing Unit. The GPU is optimized for parallel processing and complex mathematical operations required for rendering and manipulating graphics.

ARM Mali GPUs are considered to be a good option for mobile devices, providing a good balance of performance and power efficiency, and are widely used in many popular smartphones and tablets. We use AnTuTu app to analyze the performance of this device. It is designed to measure and evaluate the performance of different hardware components of a device, including the CPU, GPU, RAM and storage.

Display

This 5 inch smartphone comes with a TFT display. TFT technology employs thin-film transistors, which are small semiconductor devices, to control the brightness and color of each individual pixel on an LCD display. The 5 inch display make this smartphone pocket-friendly. The display size represents the diagonal distance from one corner of the screen to the opposite corner. Text will be easier to read, and videos will be more immersive on a larger display. This smartphone is multitouch capable. Multitouch is a feature in smartphones that allows for the detection and tracking of multiple touch points on the screen simultaneously. It enables users to interact with the device using more than one finger or touch input at the same time.

Memory

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. If you primarily use your smartphone for basic tasks like calling, texting, and browsing the web, 32GB may be sufficient for your needs. The Primo EF3 has only 8 GB of internal storage. The internal storage of the Primo EF3 (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.

Camera

This smartphone has only one camera on its back. If you have budget limitations or prioritize other features over a multi-camera system, this single camera setup can be a suitable choice. The autofocus is an important feature in this smartphone. Autofocus helps the camera to focus on a subject automatically, which ensures that the resulting photo or video is clear and sharp. The Primo EF3 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.

Connectivity

The Walton Primo EF3 like all modern smartphones, is capable of connecting to Wi-Fi networks. Wi-Fi allows devices to connect to the network from anywhere within range of the wireless access point, making it easier to work or access the internet from different locations or on different devices. With Bluetooth connectivity, you can connect your Primo EF3 smartphone to a wide range of Bluetooth-enabled devices, such as headphones, speakers, smartwatches, fitness trackers, and more.

The Primo EF3 has a GPS receiver. Many fitness and activity tracking apps rely on GPS to accurately measure and record outdoor activities such as running, cycling, hiking, or tracking routes. The Primo EF3 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 EF3 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 Primo EF3 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 EF3 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.

The battery of Primo EF3 is removable. You can simply buy a new piece from the open market and interchange it easily by yourself.

Features
