Infinix S2 Pro review perspective


Infinix S2 Pro Review: Design

The Infinix S2 Pro is a compact mid-range smartphone. If you are used to big phones, that may throw you. But even members of the Mobility Arena team who love big smartphones commented on how comfortable the S2 Pro fits in their hands. One-handed use is pleasant.

The S2 Pro is built on a metal frame, though there are bits of plastic here and there. Everything is nicely positioned to give it a very nice look and feel though. The back is metal as well.


At the top of the display, the dual camera lenses are positioned on the right and the earpiece is centralised. Below the screen, three dots represent the capacitive buttons that is standard on most Android smartphones.

At the back is a 13 megapixel camera with LED flash. Going against what has become a more common layout, the volume keys is on the left side of the phone. On the right side is the eject-able dual-SIM compartment and the power button below it.

The S2 Pro has two “loudspeaker” grills that sit astride the regular USB port at the bottom edge, while the 3.5 mm audio jack port sits at the top. Don’t get carried away by the grills though; they do not house stereo speakers.

The Infinix S2 Pro came out of the box with a customised version of Android 6 Marshmallow called XOS Chameleon. But the Android 7 Nougat update arrived a few days after the phone hit the market. The version running on the S2 Pro is 2.2.


XOS is what Infinix calls their custom user interface. It is light and breezy and includes all sorts of nifty tools. Some include the ability to block numbers for calls and SMS. The drop-down menu also gives the user direct access to several useful features, including toggling ultra power mode, high performance mode, do not disturb, screen recording, cast and scrollshot, among others.

Infinix S2 Pro Review: Network, Telephony

Telephony on the Infinix S2 Pro is of good quality and the earpiece is loud enough. The phone supports 2G and 3G networks, as well as 4G LTE networks from MTN, Etisalat, Smile, Ntel, Swift and Spectranet. Unfortunately, it does not support Glo’s band 28(700).

XOS lets the user can easily peg network mode to 4G only. There are also 3G only and 2G only modes. If it is your thing, you get to select what network you wish to use. If it isn’t, just select Auto mode and don’t worry about a thing.

The official specs sheet indicates that the S2 Pro supports the two bands used by US GSM networks, so if you want to use the phone for voice calls in the United States, you are good with this sleek guy.

Infinix S2 Pro Review: Display and Multimedia

We have mentioned that the S2 Pro has a 5.2-inch display. If you are a fan of big displays, this will likely throw you. We are told that there is a layer of protective glass on the S2 Pro. It isn’t Gorilla Glass though but Dragontrail glass.

The display is bright and cool as well. It is one that we like very much.


The loudspeaker on the S2 Pro is loud and offers fair audio quality. Coupled with the beautiful display, watching videos on the phone is a pleasant experience.

Infinix S2 Pro review: rear camera fingerprint scanner

The Infinix S2 Pro has a 13 megapixel rear camera with auto-focus and dual LED flash. On the front, it has two 13 megapixel lenses for selfies. Infinix calls it wide angle and uses the marketing term “wefie”. Of course, we put it to the test.

The selfie camera captures acceptable levels of details and also captures a wider view than the average selfie camera. A sample taken in Normal mode:

The rear 13 megapixel camera is quite capable as well. Here are some sample Photographs taken with it in Normal mode:

As you can see from the above pictures, the S2 Pro’s cameras capture good levels of details, with or without flash. In some low light situations, they sometimes struggle a bit. In normal mode, they are not so accurate in colour reproduction though, especially in the case of the rear camera. The rear camera tends to produce a toned shade of the subject image’s real colours. Still, the resulting pictures are good. But Infinix makes up for it with a range of pre-set filters.

Infinix S2 Pro review: camera filters

The cameras offer up to 9 possible filters you can apply while shooting pictures. That way, you have a great deal of control over how images turn out. They can be more vibrant or cooler or come out in monochrome. The playground is yours.

Infinix S2 Pro Review: Multitasking/Performance

While the processor of the S2 Pro is an octa-core 1.3 Ghz unit, with 3 GB of RAM, the phone provides smooth running. Switching between apps is smooth. Equipping the S2 Pro with 3 GB RAM was a mighty great move by Infinix. If you are interested, here are the benchmark results that the phone posted:

  • Geekbench 4: 623 Single-Core; 2514 Multi-Core
  • AnTuTu 6: 39212

It also helps that the S2 pro has 32 GB internal storage, though you have only about 22 GB usable from the start. Wait. All of 10 GB is used up by system resources? You can expand your storage by using the second SIM slot for a micro-SD card instead.


Infinix S2 Pro Review: Battery life

With a 3,000 mAh battery and a 5.2-inch display, the S2 Pro provides good battery life. On a constant 3G connection, the phone took me through the work day and would often deliver its first low battery warning around 6 pm. On a 4G connection, it performed much less and would throw in a low battery alert around 4 pm.

Infinix S2 Pro Review: Final Words

We are great fans of the S2 pro here at Mobility Arena. However, we are also very unforgiving that it lacks support for Glo’s 4G network, something that TECNO’s Camon CX – which costs about the same – supports. We don’t know what Infinix Mobility’s excuse is, and when we find out, we won’t accept it.

Despite this big grouse of ours, we like the S2. It ticks so many right boxes. It looks and feels good, and it is a good performer all round. If you do not need to use 4G on Glo and do not need a big screen, this is a smartphone you will enjoy using. There are not a lot of N66,000 phones that offer you 3 GB RAM and 32 GB internal storage. If you like the S2 Pro but would rather spend less, you can check out its slightly less capable sibling, the Infinix S2.

  2. Hi Dave, it has been ages since Motorola phones were on sale everywhere in Nigeria. Of recent, Lenovo has been doing some marketing but nothing heavy.

  3. This phone is really great, but not supporting Glo’s 4G isn’t cool. Infinix ought to make it compatible with 4G networks available in its target markets.

  4. BSJD,

    The S2 Pro’s dual selfie camera beats the Lumia 950’s selfie camera hands down. That’s one area the 950’s age shows.

    But as far as the main camera is concerned, the Lumia 950 outshines the S2 Pro’s hands down.
