Infinix Hot S3X is another astonishing smartphone from Infinix and also an edition of the standard Hot S3 that was released earlier this year.

The phone comes with a large display which has a higher resolution, compared to Hot S3.

Infinix Hot S3X Review

Infinix Hot S3x is an epic smart device that was launched some day ago, by Infinix Mobility. The phone is a high-end smartphone and came out as a surprise because the market did not expect its release. The phone is now available for purchase in Nigeria; a build of the phone can be bought on Jumia or Slot. It sells for about 63,000 NGN, 40 percent more expensive than Infinix Hot S3.

This smart phone is also a 4G LTE smart device. A user buying this smart phone will likely use the phone for about a year, so the support for 4G will make this phone remain relevant in 2019. Had the phone not support 4G networks, it will have made it quite worthless and even hampered its sales.

In some places in Nigeria, 4G networks are very poor. To avoid a user being disconnected in such areas, this phone also supports 2G and 3G networks.

Unlike Infinix Hot S3, Infinix Hot S3x uses micro SIM cards, not nano-SIM cards. If a user of Hot S3 desires to upgrade to Hot S3x, they will have to get micro replacements of their current SIM cards or buy new micro-SIM cards, Hot S3x is a dual SIM phone.

Infinix Hot S3x has a classic appearance. The design of the device is a result of the work of Infinix team of designers which is made up of people with great artistic sense and experience. The phone is a little larger, measuring 156.70 x 75.30 x 8.30 mm. As it can be seen from the dimension, the phone is also slimmer. This comes with a metal case which can be covered with any of the three colours: deep blue, Milan black, and space grey.

Infinix Hot S3x may not be only called a smartphone, it can also be called a phablet. The phone has 6.20 inches display which is much larger than that featured in the standard Hot S3. The smart device’s display has a 720 x 1500 pixels which is necessary to avoid its pixel density being lower than 250 ppi. The display pixel density of this phone is 269 pixels per inch. The display is unfortunately not an AMOLED display, it is rather an IPS LCD.

The epic Infinix Hot S3x can either come with a 3 GB RAM or a 4 GB RAM. The 3 GB RAM build of the phone is the build that costs about 63,000 NGN. The 4 GB RAM build costs a little more than the 3 GB RAM build. For many high-end smartphone users, 3 GB of RAM will be adequate for their operations. However, a buyer who has a few more thousand to spare can go for the 4 GB RAM build of the phone.

Infinix Hot S3x is championed by the same Snapdragon 430 chipset that champions Hot S3. This chipset is a chipset of one of the first-class chipset makers in the world, Qualcomm. As Qualcomm chipsets are known for, Snapdragon 430 is of high quality and power-efficient. The chipset is made up of eight cores put into two groups of four. A set of these four processors have a common processing speed of 1.40 GHz.

As expected, the operating system (OS) run by Hot S3x is the Android 8.1 Oreo OS. This smartphone does not only meet up to our expectation, it also goes beyond it by featuring an unmodified build of the OS. In other words, Hot S3x is an Android One smartphone. Being an Android One phone means a user will definitely have room to upgrade their OS to Android 9.0 Pie. Not only that, they’ll also have room to upgrade to Android 10, when it becomes available.

Infinix Hot S3x uses a 32 GB flash storage for storing data permanently. In this present smartphone age, a 32 GB storage will be adequate for a lot of Android smartphone users. Despite the fact that this internal storage space will very likely be satisfying, the phone has support for micro SD card. Any good micro SD card that is not more than 128 GB in capacity can be inserted into the phone’s SD card slot.

Hot S3x comes with a total of three cameras, two 13 MP cameras and a 2 MP camera. One of the 13 MP alongside the 2 MP camera, sit on the rear side of the smartphone. As expected, the other 13 MP camera is in the front of the phone. Infinix Hot S3x has LED flash on both its front and on its rear side.

Infinix Hot S3x is an improved version of Infinix Hot S3 and one of the aspects where this smartphone saw improvement is in the aspect of the display. The phone comes with a large display which is 6.20 inches, compared to the 5.65 inches featured by Hot S3. Using a large display is well-known to give way to a better user experience, and this is no doubt a very cool thing for users of the phone.

The display of Hot S3 is not only large but also has a higher resolution. An increase in the display resolution is essential for the device not to produce poor quality graphics. The phone’s display comes with a resolution of 720 x 1500 pixels. This display resolution leaves the smartphone with a pixel density of 269 pixels per inch (ppi).


Apart from being popular because of the display, Infinix Hot S3x is also popular because it is one of the very few Infinix smartphones using a chipset of the classic Qualcomm chipset maker.

It is unknown why Infinix has not been using Qualcomm chipsets like its competitors, but it seems the manufacturer is ready for a change. Qualcomm chipsets are well-known to be great and powerful, so if Infinix Mobility continues using Qualcomm chipsets, it will be a very good thing for Infinix smartphone users.

The Qualcomm chipset championing the hardware of Infinif Hot S3x is the Qualcomm Snapdragon 430 chipset. This chipset is a popular chipset among high-end smartphones, and its popularity is due to its excellence in operation. The chipset excels in tasks chipsets of its level can’t.

Qualcomm Snapdragon 430 is an octa-core chipset. As expected, the processors of this chipset exist in two sets. A set of these processors have a processing speed of 1.40 GHz. The cores of the other set have a processing speed much higher than 1.40 GHz. Apart from being powerful, this chipset is also very power-efficient, when compared to some other chipsets.


One of the major beauty of Infinix Hot S3x lies in its operating system. The smartphone runs the version 8.1 of the Android operating system. Hot S3X does not just run Android Oreo, the phone runs the unmodified build of the operating system. In other words, the phone is one of the few Android One smartphones.

Having an Android One smartphone has many benefits, and one of them is in the aspect of the operating system. Ordinarily, Infinix, Tecno and their likes equip their phones with a modified version of the Android OS. That is why we see stuff like HiOS, XOS, etc. This hardly has any benefit to the user of an Android smartphone. This furthermore makes its impossible for phones to receive updates from Google, when new versions of Android come around.

However, since Infinix Hot S3x is an Android One smartphone, it is guaranteed to get the opportunity to upgrade from Android Oreo to Android Pie. The phone will also get OS upgrade when Android 10 is released and Google rolls out an upgrade for Android One smartphones.

The advantage of Hot S3x being an Android One smartphone is not limited to OS upgrade. Being an Android One phone also makes the phone more secure. The Android OS has always been criticized by people for security issues. While Google has been working very hard against this issue, modified versions of the OS has hampered some Android devices from being secure as they should. However, with Hot S3x being an Android One phone, it can always get security updates directly from Google, whenever these security updates are rolled out.


Infinix Mobility produced Infinix Hot S3x with great intelligence. The phone comes with either 3 GB RAM or 4 GB RAM and some people have condemned the company for not featuring a 6 GB RAM in the device. While it is true that phones underperform without adequate RAM, it is untrue that very large RAM will bring very great performance.

In the current smartphone age, an Android phone does not need more than a 4 GB RAM. Equipping a phone with RAM larger than this is pointless because it has more disadvantage than advantage.

One of the disadvantages of equipping an Android phone with excessive RAM is that the battery of the phone gets wasted. The larger a RAM is, the more power it draws, even if it does not operate at full capacity.


Infinix Hot S3x has an internal storage capacity of 32 GB, and a very large percentage of Android phones will find this storage space enough. Just like every other Android smartphone, the operating system of this phone is on this device, which also means the total free space of the phone will be less than 32 GB.

For one reason or the other, a user of the Hot S3X might need to provide more storage space on the device. In such a situation a micro SD card not more than 128 GB can be inserted in the storage slot of the phone. A user of the phone can alternatively use a USB flash drive if they desire to.
