The smartphone has two nice cameras that produce outstanding pictures.

Infinix Hot S3 Review

Infinix S3 is a 4G LTE smart device. The phone works with fourth-generation networks of all mobile network operators in the country. However, smartphone users who have been using their SIM cards before 4G networks were rolled out in Nigeria, will need to upgrade their SIM cards, to use the 4G network of their mobile network operator. The smartphone not only supports 4G networks, it also supports older generations of mobile networks.

Infinix S3 is a dual SIM smartphone, allowing a user to use two SIM cards, without having more than one phone. The SIM cards used by this phone are nano-SIM cards. If your SIM card is a micro SIM, you can walk into an outlet of your mobile network operator, to get a nano SIM.

S3 has a nice appearance, but thick like majority of Infinix smartphones. However, its thickness does not make the phone ugly as the designers of the phone took the thickness of the phone into consideration when designing it. This smart device has a weight of 150 grams and comes in only two colours. A build of the phone either comes in sandstone black or brushed gold. These colours both make the phone look awesome, although many buyers of the smartphone prefer sandstone black.

S3 has a 5.65 inches liquid crystal display (LCD). 2018 high-end smartphones are known to feature 5.50 inches or 6.00 inches displays. Infinix Mobility chose to do something different with the display, featuring a 5.65 inches liquid crystal display (LCD). Infinix S3’s display has a resolution of 720 x 1440 pixels. A 5.65 inches display and a display resolution of 720 x 1440 pixels infer that this smart device has a display pixel density of 285 pixels per inch.

Infinix S3 stands out among smartphones, with its 3 GB random access memory (RAM). The market has a lot of very nice phones that have RAM capacity as their only catch, but S3 stays out of that category. The phone is not only nice in appearance, it also comes with a large 3 GB RAM. S3 uses a Qualcomm chipset as its chipset. Qualcomm chipsets are quite expensive, but they are always known to be remarkable. The Qualcomm chipset in question is Snapdragon 430.

The operating system that Infinix S3 runs is the Oreo version of the Android operating system. The Oreo version of this operating system has a lot of new features that make using the Android platform more enjoyable. Furthermore, the edition of Android 8.0 Oreo this phone runs is the standard edition, not the Go edition. However, this does not mean the smartphone cannot run Android Go apps.

Infinix is not known for producing smartphones with jaw-breaking cameras, in the past. In recent months, the manufacturer has been rolling out phones with great cameras. This is not only nice for Infinix lovers, it also makes them compete better with their competitors. Infinix S3 is one of the Infinix smartphones with remarkable cameras, featuring a 20 MP camera as its selfie camera, and a 13 MP camera as its rear camera.

Infinix S3 has a fingerprint scanner, as expected from a 2018 high-end smartphone. The introduction of fingerprint scanners into the technologies of mobile phones has opened the way to a lot more possibilities for smartphone users. One of the applications of this technology is the unlocking of mobile phones.

Infinix Hot S3 features a number of sensors, some of which are an accelerometer, gyroscope, proximity sensor, compass, and light sensor. These sensors, just like the fingerprint scanner, all expand the capabilities of this smartphone in many ways. One of the most interesting applications of the accelerometer is in simulation games.

Infinix Hot S3 uses a 32 GB flash storage as its internal storage device. A large percentage of smartphone users will find this storage space to be adequate. It is furthermore unlikely that even people who are storage-space hungry will require more storage space in the first 3 months of using the phone. Just like a lot of Android smart devices, Infinix S3 can be provided more storage space using a micro SD card.



For a long time, Infinix Mobility has been known to produce only average smartphones. The manufacturer hardly engages in the production of epic smartphones, like Tecno, Gionee, Samsung, and their like. However, this year has been quite different as the manufacturer now seems to be interested in joining the trend.

In February 2018, this Chinese smartphone company released the epic smartphone tagged Hot S3. The smartphone is more known for its powerful selfie camera. The phone has a powerful 20 MP camera as its selfie camera, and this camera takes epic pictures and videos. Apart from this camera being very powerful on its own, it also has loads of enhancements that add to its power.

The rear side of Infinix S3 features a 13 MP camera which operates with the help of software and hardware that add to its capabilities. One of the hardware that assists this camera is a bright LED flash. With the LED flash, dark places can be illuminated, making it possible for the camera to take pictures in places it would not have ordinarily been able to.


The chipset in Infinix S3 needs a memory to operate. With flash storage being cheaper, the smartphone could have used a flash storage as its main memory. However, the fact that flash storages are not optimized for random access makes it impossible for them to be used as main memory. Rather than using an unoptimized flash storage as main memory, the chipset of this phone uses as main memory, a special kind of memory that is optimized for random access.

This random-access has a capacity of 3 GB and will no doubt be okay for the majority of Android smartphone users. With such a large RAM, the phone will seamlessly run the heaviest Android apps and Android games. Unlike in the case of permanent storage, the phone cannot be provided more RAM if a user desires to. If a user desires a larger RAM, they should consider getting S3x or some other Infinix smartphone.


Infinix smartphones are generally known to feature large displays, and this smartphone does not disappoint it that aspect. While many mid-range smartphones come with 5.50 inches, this phone comes with a 5.65 inches display. The display of this smartphone is an in-plane switching (IPS) liquid crystal display (LCD). The display is power-efficient, like the IPS displays featured by a lot of mid-range phones.

Infinix Hot S3’s display has a resolution of 720 x 1440 pixels. This resolution is one of the 2018 standards. The resolution causes the display to have a pixel density of 285 pixels per inch. A pixel density of 285 pixels per inch ensures this smartphone produces standard graphics.


Infinix Hot S3 has a good appearance. It is large, light, but thick. Its thickness, however, does not make it ugly. The phone has a length of 152.30 mm and a width of 72.80 mm. Its thickness reads 8.40 mm while its mass reads 150 grams. Despite the fact that the phone is large and thick, it still manages to have a light mass; this is no doubt a good work from Infinix Mobility.

Mere looking at Infinix Hot S3, the phone appears like a mid-range smartphone. The phone has a plastic body and comes in only two colours. A build of the phone can come in either sandstone black or brush gold.


The chipset that champions the system of hardware in Infinix Hot S3 is a Qualcomm chipset. The chipset has four processors which work collaboratively and simultaneously. The Qualcomm chipset is specifically known as Qualcomm Snapdragon 430. The processors in this chipset have a common processing speed of 1.40 GHz. Talking about the cumulative speed of these cores of the chipset, the chipset has a processing speed of 1.60 GHz.


With the size of Android apps rising every day, it is important that smartphones come with larger storage space. Just a few years ago, the heaviest Android game was less than 500 MB. Today, the heaviest Android app is well over 2 GB. It isn’t only games that have grown in size, other apps have also grown in size.

Owing to the ever-rising size of apps, Infinix S3 comes with a 32 GB flash storage. In this current smartphone age, 32 GB of storage space should be enough for the majority of Android users. However, if there is the need for more storage space, a user of the phone can insert a micro SD card into the phone, to give it additional storage.


Infinix Hot S3 comes with some nice and very useful technologies. The smartphone comes with the Wi-Fi technology. Giving a broad description, the technology makes it possible for the smartphone to connect wirelessly to computer networks. The hardware that makes it possible for the phone to connect wirelessly to computer networks, also makes it possible for the phone to create a computer network.

Infinix Hot S3 comes with the Bluetooth technology which also opens up way to a pool of capabilities. The Bluetooth technology can be used to do all sorts of sharing as well as communication. This technology is also a medium through which the smartphone and peripheral devices can interact.


The graphics processing of Infinix Hot S3 is handled by a Mali graphics processing unit (GPU). This graphics processing unit is specially designed to process graphics-related tasks efficiently.

Infinix Hot S3 has a 4000 mAh Li-Po battery as its source of power. Apart from having such a powerful battery, the phone also has a rapid-charge system which helps charge the device full under 3 hours.
