I recently wanted a tablet. The only thing it had to be able to do was showing pictures and videos and so I thought I would have a go at buying a cheap Chinese tablet from Aliexpress. Didn't like any of the cheap local tablets.
After many minutes of research, I went for the great world famous Dongpad T900.

For $A123 delivered (by DHL mail), I got myself a 10" 1920x1200 IPS screen, 4G RAM, 64G ROM, 8 core 2GHz tablet with 3G and 4G dual SIM phone. 12G camera. 5000 mAh battery. Not a bad! The phone did all the Australian 3G bands and a few of the Australian 4G bands.
It arrived in 11 days complete with screen protector, Australian power pack, earphones and microUSB to female USB adapter so you could plug USB memory into the tablet. Packing was superb. Impressive! It is not a bad tablet to use - screen seems good, the applications I needed all work, GPS worked well. Ran Netflix pretty well.
The thing I hadn't realised was the creative magic of the Chinese manufacturer - it went far beyond anything I was expecting.
First noticed something funny about the ROM - when I stored 1G, the free memory went down by 4G. Yes, they hacked the Android OS to multiply ROM space by 4! It really had 16G of ROM.
With the 4G RAM, only 2G was useable. The other 2G of RAM is reported to be there but nothing can use it. Hmmm.
Next the screen. Android reports it as 1920x1200 just as advertised. I did some testing though and it is really 1280x737 pixels - again half the specified space.
Now I guess if you are on a roll, why stop?
The specified OS was 7.0 but the API level is 22 - that is Android 5. Checked for Android 7 features - No, they did't work! Android 6 features? No, definitely not! They have faked the Android version!
Then I tested the back camera (which I don't need). It claims 12 MPixels but it is worse then a 640x480 pixels camera. In fact video mode produces a way better picture then the still camera mode. Looks like the software they added to make their low res camera appear to be 12MPixels destroyed the functionality of the camera.
May as well test the front camera - it is also pretty bad and very narrow angle, so I got a great video capture of my nose.
So on to the processor - specified as the Mediatek MT 8752 8 core 2GHz ARMv8 processor. A really good CPU. The Android OS confirms this, but also confirms it as a ARMv7 CPU!. The benchmarks were well under half the expected speeds, and the GPU was a Mali-400MP. Funny as the MT8752 has a Mali-T760 GPU. Yes, they hacked the Android not only to fake the CPU model, but it seems they also fake the number of cores and they probably double the reported CPU core speeds. It appears to be a 2012/2013 era ARMv7 4 core CPU probably running about 1GHz. It is not the fastest tablet, but it is usable.
Just finished testing the specified 5000mAh battery. I took it down to under 1% and recharged with the tablet off. 3800mAh to fully recharge. I hadn't expected it to be that good after all the previous results.
How about phone. Amazing! It works. However, the inbuilt antenna is really bad and when connected, the phone signal icon shows 4G next to it even when connected to 3G. The hackers couldn't help themselves.

As long as the signal is not weak, it really does work.
I was just amazed at how it wasn't one or two things faked - it was absolutely anything they could fake. I probably still have more treasures to discover. The reason for posting this is just to let people know how fake the cheap tablets can be. There will be many buyer who never realise the tablet is fake since all the faked specs are confirmed by the Andoid OS and by the CPU-z app they preinstall. They even pre-install Antutu 4 benchmark app that seems to get a decent 60,000 benchmark, however if you try and upgrade Antutu, the upgrade fails.
As I said, I have a tablet that is actually good enough for the job at a pretty good price. The 720P screen is not bad at all and the construction quality seems fine. Speakers a bit tinny, but adequate for a cheap tablet. I have heard that the screen glue can start to separate with time.
I am requesting a refund. The seller has offered $15, but unless I get $60 back, I am just going to put in an official dispute and claim 100% refund as it is fake. You do not have to return fake items.
The seller doesn't have my A$123 deal any more, but they are offering a 2560x1600 model instead for about A$160

What I did notice with the new Dongpad offers is that are no longer specifying the CPU, GPU. If I was a bit smarter, I could have noticed that an Armv7 MT8752 with a Mali-400MP GPU is impossible. Also in my ad, one of the photos showed Android 7.0 with API build 22. Also impossible. The API has to be at least build 24 for 7.0.
