I know the infinix Zero 4 review took a while but it’s finally here. The smart phone has been with me for over two weeks now and the full review is finally ready.

Just a quick note, as usual, I have published a video which exclusively discloses all that you are gonna be reading here. Hence, if you’d rather prefer watching a video to reading long detailed posts, I’ve got you covered.

If you’d prefer detailed review posts with some pictures, continue reading.

Infinix Zero 4 Review

Just before we dive into a proper review of the device, let’s take a quick look at the key specifications of the smart phone.

The infinix Zero 4 x555 features the following key specs:

  • 5.5inch 2.5D FHD Display with 1080p resolution
  • MediaTek MT6753 Octa-core processor clocked at 1.3GHz
  • 3 GB RAM, 32 GB internal expandable storage
  • 16 Megapixels back camera with Laser Auto-focus, OIS, LED flash
  • 8 Megapixels front camera with soft flash
  • Fingerprint Scanner
  • Android 6.0, Marshmallow customized with XOS
  • 3200 mAh battery

Having cleared the key specs out-of-the-way, let’s look at the design.

Infinix Zero 4 Design

Personally, this is the selling point of the device. The design isn’t only attractive, but also feels good in the hands.

The device features a 2.5D curved glass display which is a first on infinix smartphones. And to compliment a premium feel, is the well crafted unibody aluminum build.

Although the design looks similar, I mean, the HTC 10 comes to mind, it still holds its ground as a premium built smart phone.

At the back of the device is the 16 megapixel camera accompanied by the LED flash and the fingerprint sensor.

At the button of the device is the loud-speaker, microphone and charging port.

The top region houses only the 3.5mm Jack.

Infinix Zero 4 Display

On the display side, the infinix zero 4 features a 5.5inch display with 1080p resolution (Full HD) which is said to be protected with corning gorilla glass 3.

No doubt, the display looks sharp and of course, the 2.5D curved glass just makes the whole experience better.

Watching HD videos on the smart phone is fun and sure delivers really nice viewing experience. Thanks to the Full HD display.

Software and UI Review

On the software side, the zero 4 runs Android 6.0 marshmallow customized with XOS out of the box. The User interface isn’t really much different from what we’ve seen in most recent infinix smartphones.

The noticeable addition however, will be the ability to easily access all apps installed on the phone by simply swiping the screen upwards instead of tapping the app drawer.

You still get all the handy features on the drop down menu like screen shot, flash light, ultra power, do not disturb (turns out to be really handy), screen record, Airplane Mode, amongst others.

Audio Review

While the device clearly indicates dual speaker grills, don’t let it deceive you.

Only one of those grills serves as the loud-speaker while the other is likely just a microphone. Sound quality is pretty decent, it’s quite loud and delivers clear sounds, Not just mind-blowing.

Besides, I used the Zero 4 smart phone in recording the voice-over used in the video review. Hence, you should watch the video to get an idea of the sound recorder. However, do note that noise reduction was applied to the audio recording at final processing.

Performance and Gaming Test

On the performance side, the infinix zero 4 is powered by a MediaTek MT6753 octa-core processor clocked at 1.3GHz with 3GB of RAM. Performance on the device is smooth which is expected.

Multi-tasking works just fine and yes, I was able to run and switch between Mortal Kombat X and FIFA 2016 games without experiencing any lagging.

However, I’d like to mention that the device can get really hot under intensive use. Especially when playing games with data connection turned on. Personally, this is much of a concern but the good news is, it easily cools off when placed to rest.

Security – Fingerprint Test

If you have used any recently launched infinix phone with fingerprint scanner or you’ve tried out one, you’d know how fast it unlocks using your fingerprint. It’s really no different in the case of the Zero 4 smart phone.

Infinix Zero 4 Bench Marks

If bench marks is your thing, well, here you go.

In writing, here are the results:

  • Antutu: 38944
  • Geekbench 4: 589 single core, 2378 multi-core.

Infinix Zero 4 Camera Review

The infinix zero 4 features a 16 megapixels back camera with OIS (Optical Image Stabilization), laser auto-focus, dual LED flash accompanied by 8 megapixel selfie shooter.

The device delivers decent looking pictures. However, I wouldn’t term the result as top-notch.

I love the fact that the device comes equipped with features which can get you started with learning professional photography. By default, you have the pro settings.

This can however, be adjusted with quite a handful of professional features like manual focus, ISO amongst others.

Swapping the screen from left to right and vise versa gives room for other features like switching between beauty mode and Normal mode, panorama, Night, HDR, Gestures and more.

Unfortunately, video recording quality on the device is clocked at 720p with no room for adjustments. And less I forget, the front camera features does feature a soft flash.

Infinix Zero 4 Battery

In the midst of all of these software and hardware, the infinix zero 4 packs a 3200 mAh battery which turned out to be pretty decent – for an average user.

Being a bit of an intensive user, the battery usually wouldn’t take me through the day without having to charge at some point. Of course, the hotness which originates under intensive usage can be blamed for this.

Under basic usage like making and receiving calls, sending and receiving text messages, the battery should last you through the day and probably more. However, I’d give cuddles to the fast charging technology being put in place.

With a quick charge of about 20 minutes, you should have enough juice to last you hours under basic usage. Additionally, the infinix zero 4 has LED notification in place.

In summary, I would say the infinix Zero 4 delivers pretty well. I personally love the design. Really, I do. It’s really attractive. However, the camera bumb is a bit of a turn off. But thanks to the pouch which comes with the box. If you are a fan of pouches (of which I am not), you probably won’t notice the camera bumb as it settles into the pouch conveniently.

If you ask me, I would say the infinix zero 4 is no doubt, a premium looking smart phone. That’s it guys for the review of the infinix zero 4 smart phone. Any questions? Feel free to ask using the comment session.

  • Thanks for the review but i am making issues with changing my security pattern. I did not forget the pattern, i Just want to change into a New security pattern. Please how do i achieve this cause its been challenging. Help!!!!!!!! Thank you

  • I bought my own zero 4, after 3 day I test the finger print and fell after the first operation. It displays finger print hard wear not available, please what music ?

  • Hello Sam i can’t seem to be able to get the Zero 4 Plus any where is it not available yet? If not when would it be available. Thanks

  • Hello sam pls i wana upgrade my infinix hot note tomorrow,now av rooted it before but presently now av unroot it.pls will still there be brick during upgrading to lollipop 5.1 pls enlight me before proceeding tanx..

    • Hi Femi, if the upgrade isn’t a big deal to you, it’s best you don’t upgrade. Because, chances are, it will be bricked during the course of updating.

      However, if upgrade is a biggy, you should back up every file on your phone before initiating the upgrade. Cheers!

  • Hi. I’m supprised that you didn’t say anything about the internet and gsm features of the phone. Remember that these days, Nigeria is also moving into the 4G era and internet speed is of great concern to some of us. even if you didn’t say much, I thought you’d at least mention it as either being a 3G phone or a 4G lte supporting phone

    • Hello Vince, thanks for taking out time to drop a comment. I sincerely apologize i missed talking on the connectivity side of the device. However, I’d like to clarify that the Zero 4 is 4G LTE enabled. I may have to consider putting up a separate post to talk on the internet connectivity side though. Thanks for pointing that out. Much appreciated.

  • Thanks a lot for this review. But I’m just wondering why zero3 would have a camera of 20 mp while zero4 has just 16mp. Camera quality means a lot to me, so do you think I should just go for the zero3?

    • Hello Eunice, size of a camera megapixels doesn’t always translate to a better image quality. Really, it doesn’t. The sensor being used is what counts.

      Sight an example from the Samsung Galaxy S6 and the S7. The S7 features 12 megapixels back camera while the S6 features 16 megapixels back camera. Apparently, the S6 camera has higher megapixels count right? But the S7 takes better quality pictures compared to the S6.

      Back to the Zero 3 or the Zero 4, unfortunately, I wouldn’t know exactly which to recommend. This is because, I never used the Zero 3. Hence, I can’t tell what the camera is like. However, If you need a suggestion, I’d say, go for the Zero 4. Cheers!

      • Zero 3 is superior to the Zero 4, I don’t see Samsung or even Tecno putting a weaker and an outdated processor in the latest flagship device, Zero 3 had a Helio X10 (2.0ghz) while Zero 4 has the MT 6753 (1.3 ghz) from last year’s Infinix Note 2, this Zero 4 is a huge backwards step to the Zero 3, Why didn’t Infinix use the current Helio X20 /X25 or even the Helio P10 ( MT 6755) found in the Tecno Phantom 6, Infinix are trying to con their customers by trying to push this lower mid-range device as a premium device, most phone users these days are well informed about the technical specs of the phone that they wanna buy and won’t be fooled by the media hype of this underwhelming Zero 4. I will advise people to go for the Zero 4 plus, that’s the real Zero 4, this Zero 4 is just a side show to the Zero 4 plus and shouldn’t be priced more than Infinix Zero 3 or Note 3 but I can see that it’s about 86-89k on Jumia. Infinix should definitely expect poor sales from the Zero 4, They won’t be saved by hype in this time around.
