MECOOL KD3 Android TV Stick Review for 2022 – Bonus Tips & Tricks

This MECOOL KD3 Review was written by Troy from TROYPOINT after using the Android TV system on a regular basis for three days.

This streaming device was provided free of charge to TROYPOINT by MECOOL.  However, this review is unbiased and you will see that I point out both the good and bad regarding this Android TV Stick.  MECOOL did not have access to this post prior to publishing.

Below, you will find an in-depth review that will provide you with the information that you need prior to purchasing.

MECOOL KD3 Android TV Stick

The MECOOL KD3 Android TV Stick comes with 2GB RAM and 8GB ROM (storage).

It’s important to point out that this device is running Android TV 11 and not stock Android like many of the generic boxes use.

The MECOOL KD3 is Netflix and Google certified.  This means that you will be able to play Netflix in HD and take full advantage of all Google features such as Google Assistant and Google Cast.

This Android TV Stick also works great with Amazon Prime Video.

We haven’t seen a fully certified streaming device like this from MECOOL since their popular KM2 Android TV Box.

The MECOOL KD3 is running Google TV OS on top of Android TV 11, includes a new low-power CPU, and comes with an Android TV remote control.

Yes, this device is running the full-blown Google TV OS which I’ve only seen on the Chromecast with Google TV.

There is no doubt that MECOOL is trying to compete against the popular Amazon Fire TV Stick with the new design of the KD3.

Energy-Saving Amlogic S905Y4 Processor

One big difference from other MECOOL Android TV Boxes is the inclusion of the Amlogic S905Y4 Processor.

Yes, this is a budget CPU but its advanced power-saving feature is something to note.

This processor is known for its powerful output yet low-power consumption which will save in electricity costs.

AV1 Supported

The MECOOL KD3 supports AV1 Video (AOMedia Video 1) which also appears in their other products listed below.





This is an open, royalty-free video coding format designed for video transmissions over the Internet.

Some online streaming applications now deliver their content in this format and this Android TV stick is capable of playing it.

In the future, we will see more streaming applications stream in AV1 as opposed to H 265, etc.  Soon, it will probably be the industry standard.

It’s good to look for this standard on any new streaming device that you purchase.

MECOOL KD3 Running Android TV 11

The Android TV operating system is meant for the television and it’s great to see MECOOL embrace this.

Android TV is notably found on the NVIDIA Shield, Chromecast with Google TV, Dynalink Android TV Box, and TiVo Stream 4K as well.

Most of the generic Android TV Boxes run Stock Android and the apps aren’t optimized for the TV screen.  Yes, we can side-load some of them onto those devices but Android TV Google Play Store provides access to all applications meant for the Television.

The inclusion of Android TV into its boxes is what makes this device shine in my opinion.  You get many of the benefits of the NVIDIA Shield at a much lower price.

Google Assistant is built into Android TV so you will enjoy hands-free access to many features on this Android TV Box.

Google Cast is supported so you can easily push the contents on your phone, tablet, or computer to the big screen.

Expand Internal Storage

As with most other MECOOL Android TV devices, you can expand internal storage on the KD3 as well.  This will allow you to install apps onto a USB flash drive.

To do this, you need an OTG cable so you can connect a USB drive to the stick.

You can purchase the OTG cable directly through MECOOL or Amazon.

OTG Cable through MECOOL

OTG Cable through Amazon

MECOOL even adds this as an option when choosing your configuration for the device during checkout.  You can add an OTG cable, USB drive or both.

There’s not doubt that MECOOL recognizes the need for additional storage and they make it easy to purchase everything that you need to do this.

Here are the steps that will allow you to expand internal storage on the MECOOL KD3.

1 Click Settings.

2 Hover over System.

3 Hover over About.

4 Click Android TV OS build 7 times.  Once you do that, you will see a message indicating that you are now a Developer.

5 Click the back button and then click Developer Options.

6 Turn on Force allow apps on external.

7 Connect OTG Cable and USB Drive to MECOOL KD3 and power back on.  In this tutorial I’m using a 256GB SandDisk 3.0 USB Drive.

8 You should see the USB drive listed under Settings panel.  If not, unplug drive, and then plug back into OTG cable. Click the USB drive.  If still having problems try formatting your drive as FAT32 with this tutorial.

9 Click Set up as device storage.

10 Click Format.

11 Click Move later

From now forward, all applications that I install will be added to the USB drive.  I can also go into each application through settings and move apps to and from the USB drive if I would like.  Apps that come pre-loaded on the device won’t be eligible to be moved to external storage.

I suggest running apps that require more resources on internal storage such as my VPN and Kodi.

Can’t Forget USB Drive

One problem I’m seeing with the USB external setup is that some of my past drives are still showing on the storage screen.  Typically you can click these devices and then “Forget” them so they will disappear from the list.  If I click one of these items, it kicks back to the home screen.

This is what MECOOL KD3 looks like.  As you can see, there is no option to “Forget” the abandoned storage devices.

This is what Chromecast with Google TV looks like.  You will see that there is an option to Forget this device storage.

Let’s hope MECOOL fixes this in a future update.

I suggest avoiding expanding external storage unless you have so many apps installed that it’s absolutely necessary.  It just seems that over time you will encounter problems associated with this type of setup.

Keep in mind, you can always connect external storage to store movies, TV shows, images, videos, etc. and you don’t need to expand internal storage to take advantage of that.  Just install a file manager such as X-Plore through Google Play and you will be good to go.

You can also use the OTG cable for other purposes such as connecting an Ethernet hub such as the one pictured below.

Netflix & Amazon Prime Video

Most generic Android TV Boxes don’t support HD video in either Netflix or Amazon Prime Video.

Maybe we shouldn’t be referring to MECOOL as a generic Android TV Box manufacturer anymore?

Thankfully, Netflix and Amazon Prime Video works in full HD on the MECOOL KD3 and it comes pre-installed.

Can’t Uninstall Netflix or Amazon Prime Video

One strange thing I noticed is that both Netflix and Amazon Prime Video are baked into the MECOOL KD3, meaning you can’t uninstall these two applications.

I’m wondering if they are using some sort of loophole for certification of these two applications.  I personally don’t use either of these services very much and it would be nice to free up some valuable space on the internal storage of this device.

Side-loading Applications on the MECOOL KD3

I used the TROYPOINT App with the Rapid App Installer and installed all of the most popular APKs and my favorite IPTV service.

All of the side-loaded apps that I installed worked great with no problems whatsoever.

The Amlogic S905Y4 processor does an excellent job playing HD quality video, including 4K content.

3rd Party Launchers Work

Yes, 3rd party launchers such as Wolf Launcher work great on the MECOOL KD3.

Many of you are looking for a Firestick replacement since Amazon shut down the ability to run custom launchers.

I’m happy to report that the KD3 works great with 3rd party launchers in conjunction with Launcher Manager.

MECOOL KD3 Remote Control

The quality of the remote control has become an extremely important aspect of these various streaming devices.

The MECOOL KD3 comes with a remote control specifically dedicated to the Android TV operating system.

It also includes four shortcuts to popular applications such as YouTube, Netflix, Prime Video, and Disney+.

This remote allows you to control the volume and power on your television as well.  When going through the setup process, you will be presented with a wizard that will get the remote connected to your TV.

I like the remote and the fact that we can control our TV is a huge plus.

I paired my NVIDIA Shield game controller with the MECOOL KD3 and tested some of the more popular games.

I didn’t experience any lag and the game performance was excellent on this Android TV Box.

The ability to expand internal storage (mentioned above) should appeal to gamers if they run out of space to hold all of their games.

One game can quickly reduce your storage by 1 GB or more.

MECOOL KD3 Download Speeds

I used Analiti Speed test app for the following tests.

I have 1 GB Fiber download speed plan through my Internet Service Provider.

During the WiFi tests, I am connected to the 5Ghz band on my Asus AC3100 Router.  This router resides in the same room as my MECOOL KD3  (approximately 20 feet away from wireless router).

I’m using IPVanish VPN as my VPN on Chicago Server 04 (chi-a04).

Major Differences Between MECOOL KD3 & Chromecast with Google TV

As mentioned earlier in this review, the KD3 reminds me of the Chromecast with Google TV.  The main reason for this is because it is using the same Google TV operating system.

So, the question is whether you should buy a MECOOL KD3 or Chromecast with Google TV?

There are a lot of similarities but here are the major differences that I see.

Android 11

The new MECOOL KD3 comes equipped with Android TV 11 whereas the Chromecast with Google TV currently still uses Android TV 10.

You would think that this is a big deal but it really isn’t.  I don’t see any glaring difference between Android TV 10 / 11 on these devices.

I personally never get too hung up on the version of Android that these streaming devices run on.

No Winner – All Square


It’s easier connecting peripheral devices such as USB storage, Ethernet hubs, etc. to the MECOOL KD3.

The KD3 uses a Micro-USB connection for power therefore we can use an inexpensive OTG cable to connect accessories.

The Chromecast with Google TV uses a USB-C connection for power so we must use a specific USB-C hub as not all of them work with the device.  This is also more expensive than purchasing a $5 OTG cable.

Winner = MECOOL KD3

Download/Upload Speed

Both the MECOOL KD3 and Chromecast with Google TV have comparable download/upload speeds.

No Winner – All Square

Future Updates

There is no doubt that you will see more frequent updates from Google for the Chromecast with Google TV.  Unfortunately, we haven’t see many updates from MECOOL for their existing devices.

Winner = Chromecast with Google TV

AV1 Support

The MECOOL KD3 does support the new AV1 codec and the Chromecast with Google TV does not.

Winner = MECOOL KD3


MECOOL KD3 = $56.70 with “TROYPOINT” coupon code.

Chromecast with Google TV = $49.99

Winner = Chromecast with Google TV

If I had to choose between the MECOOL KD3 and Chromecast with Google TV, it’s extremely close, but I would personally choose the Chromecast.  We’re going to get more updates with the Chromecast with Google TV and I don’t see the bugs on that device that I currently do with the MECOOL KD3.

But, if you’re someone who needs a better way to connect peripherals such as USB drives, Ethernet hubs, etc. I would lean toward the MECOOL KD3 due to OTG cable support.

If MECOOL would have added additional internal storage, this would be a no-brainer and I would choose the KD3.  More on this in my conclusion at the bottom of this review.

Important Note:  Google is expected to release a new Chromecast with Google TV model in 2022.  Recent rumors indicate more internal storage and support for the AV1 codec.  So, if you’re thinking about buying one of these you may want to hold off and see what the next few months bring.  Hopefully, we don’t need to wait until the holidays to see this new streaming device!

Final Thoughts on the MECOOL KD3 Android TV Box

I like the MECOOL KD3 and you will see that I have given it a strong rating below.

But, I wish these manufacturers would produce something that is better than what we currently have on the market.  As mentioned earlier, the KD3 is extremely similar to the Chromecast with Google TV.

The biggest complaint about devices such as this is the amount of internal storage.  It would be great to see a streaming stick get at least 32 GB of internal storage and 4 GB of RAM.  Do something better than what’s currently on the market.

It seems that these technology companies simply try to keep up with their competitors rather than beating them.

Do I like this better than the Amazon Fire TV Stick 4K Max?  Yes I do.  Now that Amazon is pushing  out updates to block 3rd party launchers, I’m starting to give up on them.  What will they take away from us in the next Firestick update?

The MECOOL KD3 is a nice streaming device, especially for those who want to expand its capabilities with accessories through an OTG cable.
