Infinix recently launched the new Infinix S4 in India with a starting price of 8,999 Rupees. The device has a single variant with 3GB of RAM and 32 GB of internal memory, this price segment faces stiff competition from several other well-known brands that have made a success in the price range. The Infinix S4 offers a three-camera setup at the back and a beautiful design, these aspects add value to the smartphone making it a good choice. The strong question is, with stiff competition from Xiaomi and Realme in the under-10,000 Rs segment, does the Infinix S4 have the performance it needs to make it a product worth buying?
In this review, we test the Infinix S4 and use it throughout the week to understand its strengths and weaknesses.
Design and Display
The Infinix S4 has a sleek design and has a glossy gradient back design, while the back is made entirely of plastic, the device still looks pretty because of its sleek gradient design. The back of the Infinix S4 comes with a three-camera AI setup aligned with a four-LED flashlight to support sufficient light in low light conditions. The device also has a fingerprint sensor on the back of the device just above the Infinix brand. The front of the device is mainly the display, on the Infinix S4, there is a droplet-shaped notch, which contains the device’s selfie camera. As in the case of most other phones, there is an option to hide the notch if you do not like them.
The device comes with volume and power controls on either side of the device. On the left side of the device, there are also two SIM cards and a microSD card slot. The underside of the Infinix S4 has a micro USB port and speaker grid along with a 3.5 mm audio jack. The front of the screen is mainly a large 6.26-inch screen with HD + resolution, the frame rate on the device is 19.5: 9.
The device’s color reproducibility is decent and the display provides a satisfying viewing angle in outdoor conditions. In bright sunlight conditions, the device is not difficult to use and the display is bright enough in most conditions. The Infinix S4 is quite lightweight and handles just right hand although the screen is very large.
We found that the display on the Infinix S4 was quite impressive and the brightness was sufficient for comfortable use in outdoor conditions, the brightness automatically works efficiently to adjust to the environment, and we noticed good optimization software on this front. There is also an eye care mode on the smartphone to apply the screen suitable for night use. The back of the smartphone attracts a lot of stains and fingerprints because of the glossy paint that comes with it, the device also comes with a TPU box in the box to help reduce stains and accumulated fingerprints.
Performance and Software
The Infinix S4 comes with a MediaTek Helio P22 chipset based on a 2.0 GHz Octa-Core processor and has a PowerVR GE8320 GPU. The device has only one variant and has 3GB of RAM along with 32GB of internal memory. The memory on the device can be expanded up to 256GB through the microSD card slot, although the chipset on the device is not the most powerful, it helps the device handle every task daily without much lag. Surprisingly, despite throwing several apps at the phone at the same time, the Infinix S4 handles it quite well and most apps open within a second or two of touching the icon. During normal use, we do not find any noticeable latency on the device and smartphone that delivers an overall good experience.
Lightweight games like Temple Run have no problems and work very smoothly on the Infinix S4, however placing anything a little more intense has caused the phone to crash. The Infinix S4 is obviously not a phone if you are a heavy gamer and we will not recommend this handset for gaming. The performance is good for the price and nothing incredible. When we load a PUBG game, the game is set by default at the lowest setting expected, however, even in this low setting, the game still does not work without jerky and occasionally displays a reduced frame.
The Infinix S4 has the option of fingerprint and face unlock to safely unlock the smartphone, the fingerprint sensor works quite quickly and accurately without any noticeable lag. The fingerprint scanner also doubles to allow for taking pictures, accepting phone calls, and eliminating alarms with gestures. The Infinix S4 runs on XOS 5.0 software based on Android 9 Pie, a user interface loaded with a number of features and apps. The worst part about the software on the Infinix S4 is the software that comes with it.
Bloatware software on the Infinix S4 is endless, the accompanying applications are XTheme, Phone Master, Flipkart, PHX Browser, Facebook, WhatsApp, Instagram, Messenger, Weather News, Opera, the worst part about this is that some of them including XClub and Phone Master apps can not even be uninstalled from smartphones. While the above apps offer a bit of value to a small fraction of users, we’d love to have a way to uninstall these apps for people who don’t need them.
The Infinix S4 comes with a three-camera setup including a 13MP main sensor with an f/ 1.8 aperture, an 8MP sensor with an f / 2.2 aperture for 120-degree ultra-wide photography, and a 2MP camera for depth detection. The rear camera is equipped with a Quad-LED flash. The selfie camera on the Infinix S4 is also comparable and uses a 32MP sensor with an f / 2.0 aperture. The camera app on the device is simple and easy to use. There are many easy-to-access options including AI Camera, Beauty, Bokeh, and AR Shot, similar to AR Emoji on Samsung smartphones.
The AI camera on the smartphone allows to automatically adjust some shooting parameters to get the perfect shot under different lighting conditions, the camera has been trained with multiple scenes and can identify scenes and subjects captured to automatically enhance the image by adjusting some settings. Both the front and rear cameras can record FullHD and the front camera also supports features such as HDR, Selfie Portrait, and Beauty mode.
The rear camera works well at a clear price and shooting, shooting outdoors in above-average daylight with decent clarity and good overall color reproducing. The phone also does quite well in macro and close-up shooting, we noticed very detailedly in these images. Autofocus is quite fast and consistent. The wide-angle lens in the Infinix S4 succeeded in capturing good quality photography with just a hint of flexible distortion. A key feature that we noticed was that the camera detected the clouds and made the sky look much grayer than it actually was. The sky looks very different in the default AI Cam when compared to wide-angle mode.
The infinix S4’s low-light shooting ability was only average, we noticed that the image was heavily noised and the end result was excessive noise. The bokeh mode in the Infinix S4 blurs the background and highlights the subject in the shot, but the software’s edge detection is not good and we notice a skewed result. The front camera is a 32MP sensor and takes a pretty good selfie, the 32MP sensor takes very detailed photos, especially in daylight conditions. There is also Bokeh mode in the front camera to blur the background with a software algorithm. The overall color reproducing and sharpness of the machine is unless in the price segment.
The Infinix S4 is one of the only smartphones in the price range with a 32MP selfie camera, the nearest competitor is from Xiaomi at a price 1,000 Rs higher than the Infinix S4. The device offers good competition in the segment and this is a very suitable device for moderate users and if you do not like intense gaming. It has a good vivid display and long battery, the overall performance of the smartphone is at a decent level. The device’s software is loaded with a lot of bloatware and can be one of the only drawbacks of the device.
