Z28 Rockchip RK3328 Android 7.1 4K TV Box Review
Are you looking for a great TV box and can'tseem to find the right one, then you've come to the right channel.
Welcome to TV box stop, the channel wherewe feature the latest in TV boxes and accessories.
On today's presentation, we have a reviewof the Z28, Android 7.
1 4K TV Box.
After the break, we have a full review withperformance 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 havehere is this brown box that the Z28 comes packed in, with absolutely no labeling orfeatures on it.
So I'll just take a minute to unpack the contentsof 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 RJ45Ethernet 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 lightindicator, and there's nothing on the other side.
At the top, you have the Z28 logo, and atthe bottom, you have 4 rubber studs, and there are no ventilation holes.
So I'll now set this up, and when I returnwe'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 thisanimation I've never seen before.
So we're here at the launcher, and this isa 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 launcheris going to get negative reviews from some people.
So I'll just skip the rest of the launcherdemonstration and open the apps section.
So what we have here is some basic systemapps like the Google play store, Gmail, chrome browser, YouTube, and RKMC.
To complete my review, I'll install my benchmarkingapps, launcher and navigation bar to make things a bit easier.
So I'm back once again, and what I'm usinghere is the Nova launcher.
And below here, this navigation bar is theVirtual soft keys navigation bar.
Both launcher and navigation bar can be foundon 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, andbelow here is shows that the operating system is Android 7.
1.
1 Nougat.
What this means, is that certain apps thatrequire root access to work, will not work on this box until you get this box rooted.
A feature that can be provided by the manufacturervia a firmware update.
While we are on the subject of updates, thisbox doesn't come with an OTA update feature.
Which means that updates will have to be donevia an SD card or the OTG port.
Let's check the digital rights managementinformation.
The DRM information shows that the Z28 doesnot have support for any of the supported services, which means that Netflix will notplay in HD quality on this box.
Now on to some system and hardware information.
Under system information, it shows that themanufacturer is Rockchip, and the model is the Z28.
Below here, it shows that the box has 2GBof RAM, and just below here it displays the remaining memory and internal storage afterthe Android installation.
Under CPU, it shows that the CPU is a quadcore cortex A53 CPU, running on a 64bit system.
And below here it shows that the CPU clockrange is up to 1.
5GHz.
Under Display, it shows that the boxes displayis powered by the Mali 450 GPU, with a refresh rate of 60Hz.
Under network, it shows that I 'm connectedto 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 theversion is 7.
1.
1 Nougat.
and below here it shows that the box is not rooted.
Unter thermal information, it shows that thebox runs between 50 to 65° celcius.
Under the codecs information, from the listyou 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 copyspeed of 3369 Mbps, the internal memory got a read speed of 111, and a write speed of39, 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 resultsshow that this box does not have the best WiFi reception.
Which means that you're better off using theEthernet 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 thatthe 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 scoreof 2223.
And that's it for the benchmarks.
This app here, is a custom kodi build calledRKMC, so let's see what we have inside.
This RKMC is really a Kodi 16.
1 build.
However, the software programmers locked thesoftware inside the root of the box, making it impossible to uninstall or even updateto Kodi 17.
Unfortunately I have to conclude my reviewof this Z28 TV box, due to numerous shutdowns an constant freezing up.
Maybe I recieved a defective box or maybethere is something wrong with the software, but this box was a bit of a dissapointmentfor me.
Maybe someone else has had a better experiencewith this box, feel free to leave comments in the description area.
Also, the Kodi 16 app freezes the box makingit impossible to use, and with the box not being rooted, any attempts to fix or installnew versions proved fruitless.
So unless someone refutes my findings in thisvideo, or contradicts my video with one of there own, the Z28 is the first TV box I'madvising people to take caution, until something is released or done about this situation.
Thanks for watching, remember to give thethumbs up or the thumbs down where it is due, and subscribe to this channel for more TVBox Stop videos.
