Are you looking for a great TV box and can't seem to find the right one, then you've come
to the right channel.
Welcome to TV box stop, the channel where we feature the latest in TV boxes and accessories.
On today's presentation, we have a review of the Z28, Android 7.1 4K TV Box.
After the break, we have a full review with performance benchmarks to see what this box
has to deliver.
So stay tuned, I'll be back after this.
Welcome back, and as we begin, what we have here is this brown box that the Z28 comes
packed in, with absolutely no labeling or features on it.
So I'll just take a minute to unpack the contents of the box.
So in the box, you have the Z28 itself.
You get an infrared remote.
1 HDMI cable.
1 5 volts 2 amps power adapter.
And that's it, there's no users guide.
Let's have a look at its ports.
To the back, you have 1 HDMI port, 1 RJ45 Ethernet LAN port, you have 1 optical audio
port, and a power adapter jack.
To the side, you have 1 USB 3.0 port, 1 USB / OTG port, and a micro SD card slot.
To the front, you have an LED power light indicator, and there's nothing on the other
side.
At the top, you have the Z28 logo, and at the bottom, you have 4 rubber studs, and there
are no ventilation holes.
So I'll now set this up, and when I return we'll have the rest of the review.
So I'm set and ready to go.
And as I power up the box, here we have this animation I've never seen before.
So we're here at the launcher, and this is a new launcher, one I've never seen or used
before.
It has a simple design with large main buttons, and some smaller slots to add shortcuts of
your choice.
There is no navigation bar at the bottom, and no bar at the top.
I'm already anticipating that this launcher is going to get negative reviews from some
people.
So I'll just skip the rest of the launcher demonstration and open the apps section.
So what we have here is some basic system apps like the Google play store, Gmail, chrome
browser, YouTube, and RKMC.
To complete my review, I'll install my benchmarking apps, launcher and navigation bar to make
things a bit easier.
So I'm back once again, and what I'm using here is the Nova launcher.
And below here, this navigation bar is the Virtual soft keys navigation bar.
Both launcher and navigation bar can be found on the Google play store, They are free, simple
and easy to use.
Let's check to see if this box comes rooted.
And it says that the box is not rooted, and below here is shows that the operating system
is Android 7.1.1 Nougat.
What this means, is that certain apps that require root access to work, will not work
on this box until you get this box rooted.
A feature that can be provided by the manufacturer via a firmware update.
While we are on the subject of updates, this box doesn't come with an OTA update feature.
Which means that updates will have to be done via an SD card or the OTG port.
Let's check the digital rights management information.
The DRM information shows that the Z28 does not have support for any of the supported
services, which means that Netflix will not play in HD quality on this box.
Now on to some system and hardware information.
Under system information, it shows that the manufacturer is Rockchip, and the model is
the Z28.
Below here, it shows that the box has 2GB of RAM, and just below here it displays the
remaining memory and internal storage after the Android installation.
Under CPU, it shows that the CPU is a quad core cortex A53 CPU, running on a 64bit system.
And below here it shows that the CPU clock range is up to 1.5GHz.
Under Display, it shows that the boxes display is powered by the Mali 450 GPU, with a refresh
rate of 60Hz.
Under network, it shows that I 'm connected to my 2.4GHz WiFi Band, and below is the signal
strength, link speed, and the frequency.
This box does not come with dual band capability.
Under Android information, it shows that the version is 7.1.1 Nougat. and below here it
shows that the box is not rooted.
Unter thermal information, it shows that the box runs between 50 to 65° celcius.
Under the codecs information, from the list you can identify the H.264, HEVC, and VP9
decoding.
No H.265 in this list.
That's it for system and hardware information.
Now onto some benchmarks.
Let's check the memory read and write speeds.
The results show that the Z28 has a RAM copy speed of 3369 Mbps, the internal memory got
a read speed of 111, and a write speed of 39, and the SD card slot has a read speed
of 17, and a write speed of 10.
I'll now perform a WiFi speed test.
And the download and upload speed results show that this box does not have the best
WiFi reception.
Which means that you're better off using the Ethernet LAN connection.
I'll now run the Antutu benchmark.
The Z28, got an Antutu score of 35825.
I now run the Geekbench 4 benchmark.
And the final Geekbench 4 score shows that the Z28 got 605 single core, and 1616 multicore.
I now run the ice storm extreme GPU benchmark.
The Ice storm extreme, gave the Z28 a score of 2223.
Unfortunately I have to conclude my review of this Z28 TV box, due to numerous shutdowns
an constant freezing up.
Maybe I recieved a defective box or maybe there is something wrong with the software,
but this box was a bit of a dissapointment for me.
Maybe someone else has had a better experience with this box, feel free to leave comments
in the description area.
Also, the Kodi 16 app freezes the box making it impossible to use, and with the box not
being rooted, any attempts to fix or install new versions proved fruitless.
So unless someone refutes my findings in this video, or contradicts my video with one of
there own, the Z28 is the first TV box I'm advising people to take caution, until something
is released or done about this situation.
Thanks for watching, remember to give the thumbs up or the thumbs down where it is due,
