First of all, the Vido N90 FHDRK is frequently sold under two other brand names, Window and Yuandao, but the model number remains the same. They all refer to the same company. Phonetically, all 3 brand names sound alike. If I understand it correctly, Vido is the name of the company that produces OEM Android tablets. Then Vido decided to sell tablets under their own brand thus Window and Yuandao were born.
Vido mainly sells their brand of tablets within China but there are retailers who are shipping them internationally. They do not even include an English manual or documentation with their products. Make sure that the support from the retailer is good before committing to buying a Vido tablet.
So with the disadvantages associated with a Vido tablet, why should anyone consider buying one? It is because Vido tablets are among the cheapest China Android tablet PCs that you can buy. The Vido N90 FHDRK is an iPad clone with very similar specs as the Pipo M6 which we gave a maximum 5 stars rating. It is powered by a quad-core Rockchip RK3188 processor and a gorgeous 9.7 inch 2048 x 1536 pixel retina display. A Vido N90 FHDRK can be bought for about $50 less than a Pipo M6.
Please note there are 2 versions of the N90 FHD, with and without the RK suffix. The RK suffix refers to the RK3188 processor that powers the tablet. The model without the RK comes with the Allwinner A31 quad-core processor.

First Impressions
The Vido N90 FHDRK is quite a well built tablet. I expected less as it does cost $50 less so I would not have been surprised if Vido had cut some corners but I am glad to say that they did not. Overall, I would say the Pipo M6 holds an slight edge over the N90 FHDRK but I am impressed with the N90. It has a simple design and the metal band around it which gives it a nice touch. At the back is a brushed metal cover. A very iPad-like design. The rubberized plastic edges on the Pipo M6 makes it more practical for holding the tablet though.
Located along the right edge are the power button, microSD card expansion slot, HDMI port, micro USB port, power in, microphone and a 3.5mm audio jack. On the right of the top edge are the Back button and the Volume rocker button. The buttons provide good tactile feedback when pressed.
There are a pair of stereo speakers located on the lower edges on either sides of the tablet. This is a terrible placement for the speakers as the palms of my hands are often covering the speakers when holding the tablet in landscape position. You can flip it the other way round of course but it is a hassle that could have been done away with if a little more thought had gone into the design. However, the Vido N90 VHDRK is not the only tablet guilty of this sin.
The rear camera on the tablet is nicely mounted inside the housing with a round opening on the back cover. This looks much better than the ugly shiny frame around the M6 that sticks out like a sore thumb.
The tablet measures 243 x 189 x 10mm (9.6 x 7.4 x 0.39 in) and weighs 660g (1.45 lbs). This makes the Vido tablet about the same size as the M6 but slightly heavier.

| Operating System | Android 4.1.1 |
The Vido N90 FHDRK has a Rockchip RK3188 quad-core ARM Cortex-A9 CPU that is paired with a Mali-400 MP4 quad-core GPU. Benchmark tests have shown that the RK3188 with its 28nm process is quite a formidable quad-core chip set, beating out the likes of the Allwinner A31, Nvidia Tegra 3 and Samsung Exynos 4412.
It comes with 2GB of DDR3 RAM and 16 GB of Nand Flash ROM for storage. Some of the quad-core tablets only come with 1GB RAM. The extra 1GB really helps in speeding things up and reducing loading especially when multi-tasking. I would have preferred 32 GB of ROM for storage but this is not a big issue. 16 GB is a lot of storage if you are not storing a lot of media files or recording HD video. If you do need more storage, that is what the micro SD slot is for. The tablet supports storage cards up to 32GB which you can now buy for under $25. On the other hand, top tablets like the Apple iPad or Google Nexus 7 have no memory expansion support.
Both the front and rear cameras are 2 megapixels. There is no LED flash but again this is not a big loss. LED flash don’t really help much in taking photos in low light conditions unless the subject is very near the camera (less than 1m). In my opinion, the best use for LED flash is as an emergency flash light.
It comes with built-in Bluetooth but there is no GPS receiver. Vido also does not offer a 3G version of the tablet so if you do not have a tethering solution while you are on the move, the Vido N90 FHDRK may not be the tablet for you.
The battery capacity is a huge 10,000 mAh but then retina screens suck up a lot of battery. The Pipo M6 has a similarly sized battery and the battery life is about just nice.
Vido N90 FHDRK Performance
Since the Vido N90 FHDRK has similar hardware as the Pipo M6, I expected similar performance as well and I was right. The stock firmware had the same problems as the Pipo M6 initially. Performance was sluggish and I experienced a lot of lag. So I immediately downloaded and installed the latest ROM for the N90 FHDRK and I got much better performance immediately.
Like the Pipo M6, performance is not perfect and it also depends a lot on what you are doing. Running high performance 3D games do still produce quite a bit of lag but it is not entirely unplayable. That being said, you will probably find playing such games on a tablet with the same CPU but a lower resolution screen to be more enjoyable in terms of game performance.
The retina screen looks gorgeous but mainly from the high quality IPS screen used. IPS screens generally look better because of the good color saturation, contrast and almost 180 degrees viewing angle. However, not all IPS screens are created equal. So far, all the 2048×1536 retina screens that I have seen on the China tablets are extremely good quality. I’m not surprised if they all come from the same source.
The cameras on the tablet suffer the same problem as almost every single China tablet I have reviewed. The quality is poor and it is only good for taking simple pictures for the web. Photos look washed out and noise is evident even with photos taken under good lighting conditions. I wish the China tablet manufacturers would put a little more effort into the selection of camera modules.
The speakers on the Vido N90 FHDRK are a little too soft. Unless you are in a really quiet room, you will need to plug in headphones or external speakers to boost the volume. As mentioned earlier, the placement of the speakers is also a problem.
Battery life on the other hand is quite good. It is comparable to the Pipo M6 as the battery can last between 6-8 hours depending on actual usage. The tablet was tested under heavy usage with a lot of movie streaming and gaming plus web browsing. The WiFi connection was kept on at all times.
Conclusion
The Vido N90 FHDRK has very similar specification and performance as the Pipo M6 which I gave a 5 star rating. It has a great looking display, high-end specs, decent performance and above average battery life. In addition, the N90 FHDRK is also about 20% cheaper than the Pipo M6.
On the other hand, the tablet has a few issues that the M6 does not. Firstly, it does not have a 3G version. If you need 3G data connectivity while on the go, you are out of luck. Of course, you can always tether the tablet to a data connected phone or use a 3G dongle but some users may consider this a hassle they rather not have.
Secondly, the speakers on the tablet are a little too soft. While the speakers on the M6 are not that great, they are loud enough to be heard under most circumstances. So if you are up and about and if you want to watch a quick YouTube video, you may have problems with the Vido N90 FHDRK.
The other thing that you may want to consider is that the Vido tablets do not have as much open source support as Pipo tablets currently. However, this may change in the future as Vido tablets gain popularity.
If you want a 9.7″ Android tablet with retina display, the Vido N90 FHDRK is one of the best value for money.

Hi Roy,
Nice review.
Where can that “latest ROM for the N90 FHDRK” be found, and the instructions on how to install it, be found too?
Thank you.
October 8, 2013
Oops! Looks like I forgot to add the link to my review. The firmware is downloaded from the YuanDao website at http://www.yuandaocn.com/download.aspx. Look for the one that says N90四核FHDRK-4.2-20130820-ZZ. Install using Rockchip Batch Tool version 1.7. Search for this online and you will be able to find detailed instructions. Good luck!
October 10, 2013
Thank you for such a quick reply Roy.
I downloaded the firmware and Batch Tool 1.7. The problem is with instructions as I do not know which ones are correct – I found the ones for either an earlier RK chipset (like RK29xx/RK30xx) or with an earlier version of Batch tool.
Would you be so kind to point out at the correct instructions link?
Thank you.
October 10, 2013
Hi Najna. You can follow the instructions on this page: http://www.arctablet.com/blog/featured/flashing-arnova-g2-rockchip-2918-rockchip-flashing-tool/
The instructions are for the Arnova tablet. The only part that is different is how to put your Vido N90 into flash mode (Step 2). To do this, first shut down the tablet (hold power button and select power off). Then connect the tablet to a Windows PC via the micro USB port on the tablet. Press and hold the volume up key and then connect the charging cable to the tablet. If you did this correctly, the display would still be dark, but on your PC’s device manager you will see that new hardware is detected. The rest of the steps should be the same.
October 10, 2013
Thank you Roy.
Wonderful help and wonderful blog.
Just one more question:
Am I suppose to repeat this process (install the latest ROM for the N90 FHDRK) each time a new ROM appears? Or just this new one in comparison with the default one, would be sufficient for future usage?
October 10, 2013
If you are happy with the current ROM, you don’t have to replace it with a newer version if you don’t want to. Besides the official ROMs, there are also unofficial ones made by fans to fix specific problems. All ROMs either official or not come with a change log file that lists all the changes or updates. That would give you an idea if you should update or not. Last but not least, if you don’t like the new ROM, you can always go back to the old one.
October 12, 2013
Understood.
If I want to update to a newer ROM do I need to first “go back” to the default one I got when I bought the N90, and then install the newer one? Or could I just install the newer one over the already installed new one?
And by the way how to get back to the default ROM?
October 13, 2013
You just install over the existing ROM. You don’t have to go back to the default one. You can download the default ROM from the Vido ROM page.
October 15, 2013
Once again, thank you for the reply.
The default ROM could be found on http://www.yuandaocn.com/download.aspx ? Which exactly link is it? It’s written on Chinese language, sorry for ignorance.
October 15, 2013
Hi Najna. I took another look and it seems that Vido no longer posts the older versions of the N90 FHDRK firmware as far as I can tell. However, I did find this post at http://www.slatedroid.com/topic/68682-official-firware-vidoyuandao-rk90fhdrk-rk3188/ where the 2 older versions are posted. Depending on how old your tablet is, it could be one of the 2 older versions.
October 15, 2013
Many thanks once again Roy.
This website definitively deserves 5 stars on support!

Glad to be of help.

Hi Roy,
I finally got the N90 FHDRK tablet some 10 days ago. Ordered it from tomtop.com.
And I am very disappointed with it. The very first day, I experienced both Android browser and Dolphin browser crashes (while some page is loading, it simply crashes the browser, and returns to android desktop). Further more, I experienced crashes which resulted in restarting the Android (getting back to the N90 FHDRK loading screen).
I upgraded the firmware the way you told me. It works faster now. Still the browser crashes and occasional restarting of the system continue. Sometimes, after the restarting is initiated, it can’t even load back to the desktop screen – it just hangs to infinity, allegedly loading.
I saw no signs of external damage when received the package.
Is this how all N90 FHDRK tablets work???
January 7, 2014
Hi Najna. I’m sorry to hear that you are having problems with your tablet. While firmwares are seldom perfect on the Chinese tablets, they should not be as bad as you are experiencing. I suggest that you do a factory reset and see if that helps. Slowly reinstall your apps one by one to test if any of the apps are causing the problems. Good luck.
January 7, 2014
Thank you for the reply Roy.
When using Rockchip Batch Tool v1.7, instead of “Upgrade” I did “Restore”.
Did that actually erased prior to flash? Is that in fact what a factory reset is?
By the way, I only installed Dolphin Browser, and no other application.
The same problems existed (crashing Android browser and restarting) even before I installed Dolphin.
January 7, 2014
“Restore” is recommended instead of “Upgrade” so you got that right. To do a factory reset, hold Vol Up (try Down if Up doesn’t work) and Power button until the tablet resets itself. You will then be given a choice to do a factory reset that wipes out everything and reinstalls the firmware. You can also try running the tablet in safe mode. This option is available on the same menu. If all things fail, it is possible that the RAM on the tablet is defective.
January 7, 2014
Volume up+Power, did not work. Volume down+Power, simply turns on the tablet.
Is there’s a way to do a factory reset, by connecting the tablet to PC via miniUSB?
January 7, 2014
You may have to hold the buttons for quite awhile (15 secs or more). And the reset will take a long while as well so make sure it is fully charged before attempting.
January 7, 2014
Turn off the tablet. Hold volume up and plug power supply. After you see logo, release volume up. You should see recovery logo. Hold power button, press and release volume up.
See if this works.
January 7, 2014
In fact I hold it for about a minute with both combinations, and still nothing.
The battery is at 81% charged.
January 7, 2014
Thank you. It worked – meaning I got the screen with android robot lying down and a red attention triangle sing on it (this one: http://cdn.howtogeek.com/wp-content/uploads/2012/12/android-recovery-mode.jpg )
After that it took him some two minutes or so to start the system.
What confused me is that I haven’t got my default firmware, but still the new one is there (“N90_E5_9B_9B_E6_A0_B8FHDRK-4.2-20130820-ZZ-_E5_9B_BA_E4_BB_B6_E8_B7_9F_E5_88_B7_E6_9C_BA_E5_B7_A5_E5_85%B7”). And all applications are there too (Adobe Flash, Google Play, Dolphin Browser). Did I do something wrong?
January 7, 2014
The firmware would remain as the new one. However, if you do a factory reset properly, all the apps should be gone. It should also take a whole lot longer than 2 mins. Probably closer to 30 mins. Use the Vol buttons to select the wipe data or factory reset option.
January 8, 2014
Ok, I got it now.
Once I select the “wipe data/factory reset” it takes around 10 minutes, until I get this message:
“Data wipe complete”.
After that I chose “reboot system now”.
It restarted and the logo screen started to load. Remained on that loading screen for some an hour and a half, like it was stuck. I turned it off, and turned on again. The same, it remained on the loading screen for about 20 minutes. Turned it off again, and it succeeded loading it finally.
The applications are gone (unistalled), and the new firmware is still there, as you said.
The same Android browser crashes appeared again.
So you think something is wrong with the RAM memory?
January 8, 2014
It is one of the possibilities although RAM problems usually causes random crashes instead of just with a particular app.
I’m quite baffled at the problem you are encountering. Perhaps you can also ask about it on the popular tablet forums like FreakTab.
January 8, 2014
I have just in called the Chrome browser, and am having the same crash issue with it too. Thank you for the help. Will try asking at Freaktab.
