Infinix S4

Infinix S4 Camera

The main selling point of this device is the selfie camera, and that’s obviously why it falls in the S range. The front camera features a 32MP lens, with F2.0 aperture and a 1.6 µm ultra-pixel.

The Infinix S4 also comes with a triple 13MP+8MP+2MP Rear Camera which helps you capture more depth and distance. The device comes with a 6P optical lens and 1.12µm large pixels. The wide-angle lens makes it possible to capture more detail and squeeze all of these into one single shot.

AI 3D Beauty

The device also comes with an AI 3D beauty feature, which is an Advanced AI Algorithm that maps over 1024 points around our face, giving you 18 different beauty packages. The screen flash is rated 45lux. This AI feature works both for the camera and security of the device. You would be able to use the facial recognition option to unlock the device, while you enjoy more depth when taking selfies and when you do video calls and chats.

Infinix S4 Body

The Infinix S4 body comes with a glossy glass-like metal, and that just improves its feel. The device sports a dual 2.5D glass body.

Infinix S4 Connectivity

The Infinix S4 comes with a dual Nano sim+ SD Card slot, and speaking of the network, it allows you enjoy anything from EDGE to 4G LTE. The device also comes with GPS navigation, IEEE 802.11 a/b/g/n/ac;2.4G&5G rated Wi-Fi. Like every other smartphone in this range, the device comes with a Bluetooth feature for file transfers, and Micro USB 5PIN USB port.

The device also comes with a 3.5M earphone Jack, an OTG with a charging output of 5V 2A.

Infinix S4 Sensors

The device sports G-Sensor, Light Sensor, E-Compass, Proximity Sensor, Gyroscope Sensor, and a Fingerprint Sensor, making it one of the best, well-connected smartphones around.

Infinix S4 Battery

The device features a 4000mAh battery, and it can run for 36 hours nonstop on 2G talk time and 26 hours nonstop on 3G talk time. It’s often noted that using your smartphones on 4G drastically increases data and battery consumption, and the battery is often affected by how long and how extensively you use the device, so this is often a subject of debate.

On standby, the device can go for 45 days on 2G, 36 days on 3G and 26 days on 4G.

Infinix S4 Display

The Infinix S4 comes with a 6.2 inch IPS display with a resolution of HD+1520/720. The display was made with TFT (thin-film transistor, a type of LCD flat-panel display screen, in which each pixel is controlled by between one to four transistors). The wide display and its 19.9 aspect ratio and 88.6% screen allow you to enjoy unlimited movies and social media streams. The screen features a light intensity of around 45lux, which is far above the 30lux you find on most mid-range smartphones. The device also sports a 500nit brightness and 1300:1 contrast, making this display one of the best you’ll find on a smartphone.

Infinix S4 Size and Weight

The Infinix S4, coming as the latest Infinix phone on the market is also one pretty lightweight smartphone. The device is 7.9mm thick, 156mm long and 75mm wide.

Infinix S4 Operating System

The Infinix S4 sports an Android 9 Pie, the latest Android operating system on the market, so you can expect to enjoy all the very best of the latest Android OS on the new Infinix phone, coupled with the Improved XOS 5.0 that’s coming with the device. A new operating system and a fully optimized XOS 5.0 gives this device convenience, improved speed, resulting in faster app operation, higher network speeds and more. And speaking of “fast” I think it’s time to talk about memory.

Infinix S4 Memory

The new Infinix smartphone comes with two variants, and these come with major differences in memory. The inbuilt memory is 32GB for the lower and 64GB for the higher variant of the device. It also comes with a RAM of 3GB and 6GB for both the lower and higher variants of the smartphone respectively. The device also comes with an option to upgrade the memory to 128GB using a microSD card.
