At first glance, it is a little hard to believe that the Infinix S4 is a sub-Rs. 10,000 smartphone. It is well designed and the glossy gradient back is the highlight of it all. The Infinix S4 is available in three colour variants, Nebula Blue, Space Gray, and Twilight Purple. We got a Nebula Blue review unit, and it was gorgeous to look at.
While the glossy back gives an impression of glass, it is made out of plastic. However, the glossy back is a fingerprint magnet and we had to keep wiping the phone from time to time. Infinix does ship a clear case in the box, which will help keep the smudges off to some extent.
The Infinix S4 sports a big display with a waterdrop notch, and the bezels aren't too thick. Our review unit had a pre-applied screen protector, and there was an extra one in the box. The earpiece on the S4 is quite slim and is wedged between the frame and the display. We found the phone to be comfortable to hold, and it wasn't too heavy.
Infinix has positioned the power and volume buttons on the right but we found the volume buttons to be slightly too high for our liking. Nonetheless, all these buttons have good clicky feedback. This SIM tray is on the left.

Turn the phone around, and the triple camera setup is sure to grab your attention. Such a setup isn't common at this price point and we were surprised to see it on the Infinix S4. The camera module protrudes slightly causing the phone to rock when placed on flat surfaces. There is a quad-LED flash right below the camera module. The fingerprint scanner is positioned next to the camera and is easy to reach. The scanner has a matte texture, breaking the monotony of the glossy back.
At the bottom, you'll find a loudspeaker grille, 3.5mm headphone jack, and Micro-USB port, while the top of the device is completely blank.
Infinix S4 specifications and software
The Infinix S4 sports a 6.21-inch HD+ (720×1520 pixels) display with a 19.5:9 aspect ratio, and the company claims an 89 percent screen-to-body ratio. Infinix also says that the S4 puts out 500nits of brightness, and we found the display to be legible when outdoors. The display was crisp and were happy with the output, however, we couldn't find a way to tweak the colour temperature. There's an Eye-care feature that filters blue light to reduce eye strain.
Infinix has picked the MediaTek Helio P22 SoC to power the S4. This processor is slowly becoming common at this price point, and we have seen other smartphones including the Realme C2 (Review) and Oppo A1k (Review) using the same SoC.
The Infinix S4 comes in one configuration only, with 3GB of RAM and 32GB of storage. It has a dedicated microSD card slot that accepts cards of up to 256GB. Connectivity options on the Infinix S4 include Bluetooth 5, Wi-Fi, dual 4G VoLTE, and GPS. This phone packs in a 4000mAh battery and you get a 10W charger in the box.
