Is the Vankyo Matrixpad Z4 10-Inch Tablet Worth It? [2020 Update]

Launched in 2017, Vankyo is a leading brand for projectors but is now slowly moving into the tablet arena with its budget devices. The VANKYO MATRIXPAD Z4 10 inch tablet is such a device.

The 10.1” device equipped with a 2GB RAM, 32GB internal storage, and 64-bit quad-core processor that uses its price as the main selling point.

I own sneakers more expensive than this tablet.

Let’s find out if the features offered are acceptable for this price range.

Vankyo Matrixpad Z4 Tablet Review

As always, my reviews start with the exterior of the device. Let’s start with the looks and dimensions of the device.

At first glance, the Z4 looks like any other tablet but on further inspection, you can see that the device is quite flimsy, and it’s made of low-quality material. The rear panel is made of plastic while the “HD quality” screen feels like it’s also made out of hard plastic and has sort of a rubbery feeling to it.

Usually, glass surfaces are messy because you leave behind fingerprints. This doesn’t usually happen on a plastic surface, but it seems pretty easy to leave behind fingerprints on the plastic rear of the Z4.

I guess this why the device has a low weight of 1.08 lbs (0.49kg).

When I first picked up the device, it felt like I was holding a tablet without any components inside. The device felt hollow. It was as if it was a dummy model.

Under pressure, the tablet creaks a bit, but it doesn’t break unless you like drop twice or thrice consecutively from a considerable height.

Even then I doubt the “glass screen” would crack. But hey, focus on the price right?

Usually on most of the devices today you’d find the charging port on the bottom and the power button on one side and the volume buttons on the opposite side.

Weirdly the VANKYO has all the ports and buttons on the left side of the device and left the three other sides blank. The Micro USB port used for charging, the power and volume buttons, Micro SD card and 3.5mm headphone jack are all right next to each other.


Let’s move on to the display.

The 10.1” display has a resolution of 1280 x 800 which is okay for this price but again there are smartphones with better resolutions.

In terms of brightness and viewing angles, the Z4 probably scores a 0/10. Why?

The device has a max brightness of 162 cd/m2. You’re probably wondering what this is. So “cd/m2 “stands for candela per square meter and is a measure of light or luminance.

As a standard, when you do a battery test you set the device brightness to around 170candela per square meter because usually at this level you get a perfect balance between readability and battery economy in indoor lighting conditions.

So, when the device can’t reach 170 and maxes out at 162, you’re left questioning the ability of this display to be visible under direct sunlight. Viewing angles should simply be dismissed because there are none and the display is also quite reflective which makes matters worse.

The contrast ratio of 529:1 is way below benchmarks, even the much cheaper AMAZON FIRE 7 which cost exactly half of what the Z4 costs, has a max brightness of around 374 candela per square meter and a contrast ratio of 1205:1.

Moving on to the core, the above can be easily forgotten if at least the performance was satisfactory.

Ever heard of a processor brand called ROCKCHIP? Sounds more like a cookie brand to me.

The Z4 rocks a ROCKCHIP RK3066 processor with a 2GB Ram and 32GB internal Storage. The device is pretty slow and lags quite a bit. The application takes at least 5 seconds to open up and typing on the on-screen keyboard is just a nightmare.

To make things worse, the device easily heats up. Stream an HD video and feel the heat slowly build up on the ‘plastic’ rear panel.

What some users think is a slow performance might be tolerable to others. So for a valid verdict, you should always use benchmarks.

If you are not new to the hardware world, you’ve probably heard of Geek bench 4.

When measuring the CPU performance of the Z4 and comparing it to other budget tablets, tablets that cost half as much as the Z4 like the Amazon Fire 7 beat the Z4 by a considerable amount.

Moving on to battery life, you’d probably think that a device with such a low luminance could at least have a bit of extra battery life.

Sorry to burst your bubble but the Z4 average about 7hrs and 30 mins and loses to the Fire 7 yet again.

Sure, 7 hours isn’t bad for a budget tablet but with the given display, sluggish performance I’d like to think the battery drains slower.  

This felt more like a bashing than a review because the MATRIXPAD Z4 just scored poorly in all the important categories.

If it was up to me, I wouldn’t even consider this device. Usually, when I review budget devices that don’t do too well, I am considerate of my readers and recommend the product if they are strapped for cash but in this case, you’d be better off without the Z4.
