As a successor to Google's Nexus 9 tablet, I bought an inexpensive Chinese tablet on Yahoo! Auctions for 6,500 yen (shipping fee was 2,900 yen). According to the auction item description, this tablet is unused and has the following specifications.
I thought the specs weren't bad considering it had a 10-inch display with a resolution of 1920 x 1200 (IPS), Android 13, and support for 5G calls.
Regarding the Chinese tablet that was sent to me
The Chinese tablet box sent by the seller only says "Tablet PC" and does not contain any other information such as the manufacturer's name, nor does it include an AC adapter or instruction manual. It wasn't in there.
Although I think it's somewhat suspicious, I'm going to make the initial settings and give it a try.
I later found out that the manufacturer and device name of this tablet is YDJ Pad5Pro.
Operation confirmation of YDJ Pad5Pro
I started the browser Chrome and tried opening my website.
Ugh! ? Something doesn't seem right. The text on the site is rough and the GIF images are not displayed properly. Is this a GPU bug? ?
In the gallery below, the display on the left is "YDJ Pad5Pro" and the display on the right is another Chinese tablet "TPZ T10B-A".
YDJ Pad5Pro device information
Something seems strange, so I'll look into the device information. Below is the device information as seen from Google settings.
It says the system update has been updated to Android 13.0, but when I click on the details here, the last update date is August 5, 2018.
This is finally getting suspicious!
Investigating the system of YDJ Pad5Pro
In order to investigate in detail the contents of this suspicious Chinese tablet, I try to install an application that displays device information, but many applications encounter errors during installation and are difficult to install. In the midst of all this, I was finally able to install the app "devcheck".
The gallery below shows the results from devcheck.
As shown in the gallery above, the actual OS was Android 8.1 (Oreo). Furthermore, the screen resolution is a low resolution display of 1280 x 800 (WXGA). This revealed that the product description was a complete lie.
The SoC is Mediatek MT6750, and the CPU is Cortex-A53 (156MHz-1001MHz x 2 cores/286MHz-1508MHz x 2 cores). Although it has 8 cores, it is an extremely slow CPU, so 5G communication is probably impossible. GPU is ARM Mali-T860.
Also, since it's running Android 8.1, you won't be able to install many apps, and there are security issues. When I actually tested it, unfortunately, I was unable to send an email to any domain using Gmail, probably because it does not support the latest security "SPF", "DKIM", and "DMARC".
In the first place, there may not even be GMS (Google Mobile Service) authentication required for downloading from the Google Play Store.
Please note that there is no mention of Technical Compliance (Certification of Technical Standards Conformity) anywhere, so all wireless uses in Japan, such as 4G/5G, Wi-Fi, and Bluetooth, are illegal.
By the way, the Chinese tablet "TPZ T10B-A" I have has a Technical Conformity Mark engraved on the back of the tablet and on the package as shown below.
Based on the above results, I sent a message to the seller with the following message and requested a return.In the end, the return was processed and I was able to safely recover the full amount of the payment!
Regarding this product, the product I received was completely different from the product description.
After checking and confirming the device using the app "devcheck," the following specifications were found to be false.1. Operating System: Android 13.0 (displayed with Android crack)
⇒ The contents were based on Android 8.1 (Oreo). Therefore, there are some apps that cannot be installed.2. Display resolution: 1920 x 1200 (IPS)
⇒ This is a complete lie. It was actually a low resolution display of 1280x800.By the way, on devcheck, the device name is displayed as Pad5Pro, so this seems to be a counterfeit "Xiaomi Pad 5 Pro".
For the above reasons, we apologize for the inconvenience, but we would like to return this product.

There may be many people who have purchased the product and continue to use it without realizing the fact that it is a counterfeit item, but there is a possibility that such suspicious devices are loaded with malware, so please be careful when using them. You need to be very careful.
At the very least, when purchasing a minor Chinese tablet, we recommend checking the device first.
As a challenge again, I later purchased the following Chinese tablet.
