Body and Design

The Body of Infinix Hot S3 is fabricated with plastic material which is not much strong and weighty but looks elegant. The sides are curved beautifully and you will feel strong grip while holding device. It is designed in such a way that the most part of front occupied with touchscreen. It is wrong to say completely bezel less screen, bezels have reduced but not eradicated entirely. There is a great 81 percent screen-to-body ratio which means you are getting approximately full screen of 5.7 inches. There are three on-screen buttons for navigation. A Camera lens, soft dual LED flashes, and an earpiece are equipped above the screen. The 3.5 mm jack is placed on top while OTG supported microUSB port and speaker grilles are present at the bottom.

Left side is armed with a tray which has dual SIM slots and a separate microSD slot therefore you have no need to compromise with cellular connectivity. Power and Volume Keys are available at the right side. Primary Camera Snapper is mounted on the top left corner of the back. Below the primary camera, dual tone LED flash is available. Fingerprint Sensor is embedded in the top center half of rear so you will feel comfort when you want to access fingerprint scanner. Infinix Hot S3 comes in different colors but its black variant looks more beautiful. 

Display and Software

Infinix Hot S3 measures 5.65 inches diagonal screen. It has 18:9 aspect ratio IPS LCD display which is perfect from all viewing angles. The resolution is 720 x 1440 pixels which gives enough brightness to see display details with ease. The screen provides vivid and vibrant scenes under the sunlight. The color saturation is fine but contrast ratio is not good. In our whole experience with Infinix Hot S3, the display didn’t create any issue except some dull vivid colors output.

Infinix Hot S3 is running on latest Android 8.0 (Oreo) which is most favorite OS of young generation. There is XOS 3.0 overlay which gives more polished apps and gestures support. It looks slightly similar to Apple iOS. The XOS Hamming bird interface is amazing and surely you will enjoy it a lot. The XOS 3.0 runs smoothly and supports Changeable Icon Size which lets you adjust the size of icons according to your wish. Infinix Hot S3 software has beautiful Personalized Wallpapers, Various Keyboard themes, Several New Emoji, Multi Window, Multi Accounts, Super Screen Shot, Super OTG, Anti theft, some pre-installed apps and much more. There is a Freezer app which enables you to completely switch off an unwanted app and even mobile data for selected apps to save battery consumption in order to offer you to serve a long time on smartphone. 

Performance and Memory

Under the hood, an old 28nm chipset, Snapdragon 430 is working fine. The chip is not based on 14nm processor that's why the device takes trivial period to accomplish your task. There is an Octa core processor which clocks at 1.4GHz frequency to execute your several programs. Adreno 505 GPU is there which ensure the graphics are nice. There is 3GB RAM which can install your favorite games and apps easily. To get a better gaming and multi-tasking experience, you can choose a 4GB RAM variant of Infinix Hot S3. The overall performance is good and we’ve enjoyed a smooth working experience with Infinix Hot S3. In terms of Memory, you can get either of 32GB and 64GB Storage. Thanks to Infinix, microSD card slot is available for storage expansion. 

20MP Selfie Cam and Photography

Infinix Hot S3 is recommended for selfie lovers. It gets a high 20MP front camera which has f/2.0 wide aperture. There are dual tone dual LED flashlights to capture selfies with different color tones. The Selfie camera performance is amazing and commendable. You can shoot your special moments under the brilliant result. In addition, the Video calling experience with Hot S3 is superb and it won't let you down in any light. One thing is interesting that images and colors look real and natural. Beauty mode adds perfection in your selfies. With the Infinix Hot S3, you are getting also Bokeh effect which does not create perfect but acceptable blurred background selfies.

The primary rear camera of Infinix Hot S3 has 13 mega pixels for shooting. The lens is coupled with dual tone dual LED flash which helps to capture moments in low light but in reality the photography performance is not satisfactory even in daylight. The Selfie performance is super cool while the Photography performance is frustrating and aggressive. The 13MP rear camera captures standard images in some specific conditions otherwise its video recording or capturing capability is not agreeable. The HDR mode can help you to take good looking photographs and videos.

Battery and Price

Infinix Hot S3 is backed by a non-removable battery of 4000mAh. It is long lasting battery which offers you to watch and play games for a lengthy time. It can last you through your day easily. Heavy users and gamers will be pleased with longer life performance of smartphone. It takes 1 hours and 45 minutes to recharge. The Price of Infinix Hot S3 is $140 and its premium 64GB variant is available for $170.


Infinix Hot S3 is an excellent budget smartphone within this price range. Though it has old Snapdragon 430 but it runs steadily. Except its aggressive photography, Infinix Hot S3 is superb. It has 5.6" 18:9 display, 20MP selfie camera, durable 4000mAh battery, fast fingerprint scanner, latest Android 8.0 (Oreo), and all these features are available for only $140 so it is not bad if you’re going to buy Infinix Hot S3.
