Infinix S2 Review

Infinix S2 is a mid-range smartphone with a total of three cameras. The phone was released in April 2017 but has become a little outdated. When this phone was released back in April 2017, it sold for about 50,000 NGN. However, this smartphone currently sells for about 40,000 NGN.

During the time of release of this smartphone, a lot of mid-range devices did not come with support for 4G networks, but Infinix S2 had the support for networks of this generation. This support for 4G is one of the reasons why the phone has a place in the current market. Aside from supporting fourth-generation networks, the smartphone also supports second and third generation networks.

Infinix S2 is a dual SIM smartphone, but it does not use nano-SIM cards like many of the new phones. The phone rather uses micro SIM cards. This device is quite compact, having a length of 148.90 and a width of 72.10 mm. The phone is also slim, having a thickness of 8.07 mm. Infinix S2 has a weight of 137 grams which clearly shows that the phone is light. Black, rose gold, and grey are the colours a build of the phone can come in.

Infinix S2 has a small display which was standard at the time of its release. The display of the smartphone measures 5.20 inches and comes with a standard resolution. The display is also an in-plane switching (IPS) liquid crystal display (LCD) and has 720 x 1280 pixels as its resolution. When calculated, the pixel density of Infinix S2 is calculated to be 282 pixels per inch (ppi).

The chipset of Infinix S2 uses a special RAM as its main memory. This memory in question in a memory-optimized for random access, which is important to avoid inefficiency in the operation of the chipset. This RAM has a capacity of 2 GB — the RAM size generally featured by current mid-range smart devices. A 2 GB RAM will be adequate for the operation of a user of this smartphone.

Infinix S2 hardware is powered by a MediaTek chipset. The MediaTek chipset powering this phone is the popular MediaTek MT6753W chipset. The chipset is a great mid-range chipset, highly efficient, and inexpensive. The chipset is furthermore a quad-core chipset and the processing speed of its cores is 1.30 GHz.

The smartphone runs the Android operating system (OS). The version of Android this smartphone runs is Android 6.0 Marshmallow. Android 6.0 Marshmallow is one of the award-winning versions of the OS. While Android 6.0 Marshmallow is an award-winning OS, it does not really have a place in the current smartphone world, as three newer versions of the OS have been released. It is, however, possible to upgrade the version of this OS to Android 7.0 Nougat.

Infinix S2 comes with a 16 GB internal storage. While a 16 GB would not be adequate for some users, such users can get a micro SD card. With the availability of a micro SD card, a user of this smartphone can put only apps on the internal storage, and put media files in the SD card of this smartphone. Note that a micro SD card larger than 128 GB should not be used for this smartphone.

Infinix S2 is one of the early Infinix phones to feature more than two cameras. The smartphone has a total of three cameras, two in the front of the smartphone and one of the rear side of the phone. A 13 MP camera and an 8 MP camera are in the front of the phone. The rear side of the phone features a 13 MP camera which has the support of a LED flash, as expected.

Infinix S2 is a mid-range phone which comes with remarkable cameras. The phone has three cameras, and two of them are in the front of the smartphone. One of the biggest question about this phone, is how the two front cameras work? The simple answer to this question is that only one of the cameras works at a particular time. However, one of the cameras is optimized for selfie picturea, while the other is optimized for taking wefies.

The rear side Infinix S2, has a 13 MP camera that is nicely positioned. The camera is quite powerful and has enhancements which help amplify its power. One of these enhancements includes a bright LED flash which lightens dark places whenever a user of the phone tries to take pictures in the dark.


Infinix S2 is quite small. While large phones are the current centre of attraction, these days, seeing this smart may cause an individual to change the way they see small phones. The smallness of the smart is not only nice, it furthermore gives the phone some elegance. The smart device has a length of 148.90 mm and a width of 72.10 mm.

Infinix S2 has a light mass, weighing about 137 grams. The phone is not only small and light, it is also slim. Its slimness is found to be 8.07 mm. The smartphone has a plastic body and a build of it can be bought in three colours. These three colours in question are black, rose gold and grey.


Infinix S2 has a catch which is worthwhile exposing to the reader. The smartphone runs Android 6.0 Marshmallow as its operating system. At some point in the previous year, running this OS was cool. However, things have moved so fast that this OS is below the OS standard of Android smartphones.

However, it is possible for a user of the phone to upgrade the operating system to a better version. This better version is not Android 8.0 Oreo. Rather, Android 7.0 Nougat is being referred to as the better operating system. Even though Oreo comes with a lot of new features, a user can consider using Nougat, to enjoy the nice specs and features of this smartphone.

When trying to upgrade the phone’s operating, it is recommended that a user of the phone uses a 4G network or Wi-Fi to download the upgrade. This is recommended to just make things faster. In addition, it is very important a user charges their phone to 100 percent before ever trying to upgrade the phone’s OS. This is just to ensure that the smartphone does not run out of power while upgrading.

If Infinix S2 runs out of power while its operating system is being upgraded, there exists great chances that the phone will get damaged. Furthermore, repairing it after such damaged can be challenging and expensive.


The hardware in Infinix S2 is championed by a quad-core chipset. The cores of this nice chipset always share tasks among themselves, completing tasks faster. The processors of this smartphone are highly efficient in operation. Not only are these processors highly efficient in operation, but also power-efficient.

This chipset which is being talked about is a MediaTek chipset. The chipset is known as MediaTek MT6753W and the processors in it have a common processing speed of 1.30 GHz. This processing speed is just the standard speed expected from chipsets of mid-range smartphones.

Infinix S2 comes with a synchronous dynamic random access memory as its main memory. This RAM is a special RAM designed to avoid inefficiency in the operation of chipsets of this smartphone. Without such a special memory, this phone will operate at a lower speed which isn’t a cool thing.

The random access memory championing Infinix S2 has a capacity of 2 GB. This capacity is large enough to help aid a seamless operation of the smartphone. However, if this smartphone is used by people the device is not designed for, a seamless operation from the smartphone cannot be guaranteed.


Built into Infinix S2, is a Li-Ion battery packed in polymer. The battery powers all active electronic components in the phone. By active electronic components, we mean hardware like display, chipset, RAM, camera, sensors, etc. They polymer packing of the smart phone’s battery enables the smart device to be slim as it is.

The battery of Infinix S2 has a capacity of 3000 mAh. This capacity is standard in this present phone age. It will furthermore give the phone a standard operation time, after a full charge. Even though the battery is marketed as Li-Po, it is still important that it is maintained like a Li-Ion battery. This battery has an operating voltage of 5 volts.


Infinix S2 works with a permanent storage which has a capacity of 16 GB. About 5 years ago, such a storage space is an abundance that only a very few people can use it up. However, technological progress has made this untrue in this present age. In this present age, a 16 GB is only a standard, not an abundance. A user will have about 10 GB of this space to themselves, but apps and media files will eat up this storage in a matter of time.
