This is probably the Cheapest QuadCore 10.1" Tablet that China MID market has offered. Although being the cheapest sometimes doesn't help a Tablet to create an appealing taste to some enthusiasts. Zenithink knew all of that so I believe they've tried to produce a QuadCore Tablet that will surely have its place in the growing China MID market.

The new Zenithink C94 QuadCore 10.1" Tablet offers a QuadCore Freescale i.MX6Q 1.2GHz Cortex A9 processor with QuadCore Vivante GC2000 graphics which we've also found on Ampe A10 QuadCore 10.1" HD-IPS Tablet. But unlike Ampe A10 QuadCore which cost US$219.99, Zenithink C94 QuadCore doesn't have an HD-IPS display and a lower Battery Capacity of 5600mAh which is expected to serve 6hrs of continuous use. It also have a 1GB of DDR3 RAM and an 8GB of Flash Storage which are fine, one can always expand its storage using microSDCard on the Tablet's expansion slot. It also includes Wi-Fi B/G/N connectivity. The ads says it has latest JellyBean 4.1 Android OS installed but only IceCreamSandwich 4.0.4 is stated on the specs. We still have to confirm this later.

Zenithink C94 QuadCore 10.1" Tablet is available at an Online Store based in Shenzhen China for cheap price of US$179.99 including a world-wide free shipping.

Like we've said above, Zenithink didn't put an HD-IPS screen on this QuadCore device. Instead, they choose to use 1024x600px resolution with LED-TN panel which has lower viewing angles if compared to IPS screen or MVA screen but slightly better than ordinary TN Panels. We can also see the 0.3MP Front Facing Camera placed in the middle-top of the screen bezel, it should be fine for Video Calls.

Posted Image
On the bottom of the Tablet we barely notice the two LoudSpeakers located on each corner. We just hope it provides good quality of sounds so sharing musics and movies to our friends,relatives, and or love-ones during outdoor camping is possible. We still don't have any idea if Zenithink C94 uses a glass screen or a hardened plastic screen, but we hope it is Glass screen because it has high tolerance of scratch resist. Both should be good protecting the screen from unwanted scratches from everyday use.

Posted Image
The Back uses plain Plastic Shell material painted with matte white, it doesn't comes with any designs or anything to make the tablet more amusing. Just plain white with 2.0MP Rear Facing Camera placed in the middle-top which hopefully have a good quality of photos and videos. The Power Button and Volume rockers are placed in an uncommon location in the top-left corner (if we are looking at the back-shell). Near the interface buttons are the 3.5mm Audio port and the microSD expansion slot which supports max.32GB of microSDCard.

Posted Image
Just above the Power Button and Volume Rockers, you'll find the rest of Interface ports including (from left to right) 5V 2A Wall Charger port, tiny Reset hole, 2x microUSB which supposed to support OTG function for connecting any USB devices on the Tablet like external 3G-USB dongle or USB Flash drive, Zenithink also didn't remove the mini-HDMI port and should support Full-HD TV Panels for sharing your movies to a larger screen, and the tiny Microphone hole.

The Cons:

  • No IPS Screen - as we all know, IPS Screen gives such beautiful and vivid rich-color images for this cheap Tablets. If Zenithink is causing problems to keep the price lower, they could always use MVA screen like Ainol Novo7 Crystal DualCore 7" Tablet uses.
  • Low Battery Capacity - another negative effect of being the cheapest is the constraint on Battery Capacity. 5600mAh with expectation of 6-hours continuous usage might be good enough but having 7000~8000mAh of Battery Capacity is way much better and could add eye-candy for enthusiasts.
Anyway, I still believe that the Zenithink C94 QuadCore 10.1" Tablet will surely have its place in the current market. And as for the performance, we don't have much any idea on how the QuadCore will performs but it should be better than RK3066 Tablets except on gaming compatibility.


Thanks for reading...

I Have a friend who bought a Zenithink C94 on Friday. This should be here before the end of the week and as I will be setting it up for him, I should be able to answer the questions being posted here.

I can tell you this, I have an Upgraded Zenithink C91 which apparently uses the same screen. This is not an IPS screen, nor a higher resolution screen. However, visibility on my tablet is remarkably good throughout a more than 90 degree range, and the screen compares favorably in brightness, clarity, and sharpness to most tablets out there. You actually need to be looking for jaggies to see them.

Battery life does concern me, yet I have not been real happy about the battery in my own machine. Unfortunately the warranty on my battery is only 3 months. Even so, Juice Defender has allowed me to double my battery life. I Would have liked to see a better battery life for the C94. We'll see how well Zenithink has handled this.

Two things have made me think very well about this tablet before I've even seen it. One of these is that though I've looked at the AMPE A10 and SANEI N10 quad core machines, their speakers are not positioned well and quality control/battery life are real issues. I think that perhaps Zenithink learned from their experiments with the C91, C93, and C97 insofar as speaker position/battery life. The other is that I've been privileged to be around several C91 tablets, have had an Idolian Touch Tab 10, have friends who have a couple of XOOMs, two ASUS tablets, and an ARCHOS as well as two IPADs. For the most part I have been very favorably impressed with my dealer, and the support I've had from Zenithink as well as support I've had from Slatedroid. I just love my Zenithink C91.

We'll see what happens when I have hands on experience with the C94-Till then-

Rob

OK, so I am told by Zenithink that there are two versions out right now, the H8_1a and the H8_2a...
If the barcode sticker only says H8 with no 1a or 2a, you have a H8_1a C94.....

They aren't making a Jelly Bean ROM till they iron out all the bugs out of ICS, and they aren't posting a download for a C94 ROM since they are updating it so frequently....

I am also told that there are only a few 1a tablets out, and in the future all will be 2a....

They gave me a download link for the latest ICS ROMs for both the 1a and 2a versions (they are different), but they asked me not to post it (don't know why, waiting for a reply), so if you do need to reflash your tablet, PM me for the download link....

Hi, sorry I don't know how to send a PM on this forum. I think I have one of those rare H8_1a versions as my barcode simply says "H8-xxxx"

I see that the download link for the 2a version is already on Zenithink's site but not for the 1a. Could you please let me have the download link they gave you ?

Many thanks.

I don't know what to say about the C94, but here's my situation-I had a friend who bought one of these a few weeks ago. His has not arrived yet, and when it does come In I will be doing the setup for him. At present I am using an Upgraded C91 and I love it. However, I bought an Ampe A10 Quad Core tonight. It should be here on Monday or Tuesday and I am, because it has a regular USB port that can have a regular USB keyboard plugged into it, going to give my C91 to my wife-She likes a keyboard that actually has keys rather than what I like, which is a swipe keyboard. Once I get all three of these keyboards side by side, I'll be in the position to do an accurate comparison. I'll let you know what I think.

I bought this tablet from a famous site selling Chinese. After many recommendations to the seller to ship the tablet with code xxx2a-xxx (follow carefully the forum, thanks omarahum) I came up with code H8-xxxx. I opened the box and my surprise was great. With a lot of anger :cray: , I wanted to flash the tablet with the ROM xxx2a-xxx downloaded from the official website Zenithink. If fails, I return to the sender. During the simple procedure of flash, it not appeared errors or similar. After the procedure, the tablet worked perfectly. It all works. No error. The camera, volume, power, are OK. After I did the procedure root ( read on this forum somethink). Perfect ! I started to install the applications, games and so on. They are all OK. Now, a question: Why Zenithink has two ROM? I installed the 2a on tablet H8-xxxx. It all works. What are the differences between H8-xxxx and H8_2a? Maybe my tablet eats everything? Or my tablet xxxH8-xxx is near to death ?

This tablet is very nice. Designed is wonderful. Fast and accurate........ still under warranty 8)

I was told there is a slight redesign in the hardware, and if someone flashes a 2a ROM onto the 1a tablet, the sleep function might not work correctly....

Have you been able to go in and out of sleep ok? How fast does your battery drain while in sleep? I think those are the issues, but I am not sure....

The sleep in and out maybe is normal. This function is OK. I go in and out of sleep many times and Tab is up and down in normal.
From Zenithink, some notice on hardware redesign for difference 1a and 2..........

I wanted to continue to try to install the correct ROM. OK.

I have installed corrected ROM (1a) on this Tablet. Now everything is working properly. The battery icon with power disconnected is now correct. The sleeping is activated by touching the power button. Various settings are now correct.
But there is no bluetooth in Setting. In system/app there is the program bluetooth.apk

Hi guys. I have my ZTpad C94 model from ANANDA. I agree about the battery. Seems a little short for operations. Mine says ICS AOSP on imx6q (I do not know whats it means) and Android 4.0.3. Very nice tablet


I Have a friend who bought a Zenithink C94 on Friday. This should be here before the end of the week and as I will be setting it up for him, I should be able to answer the questions being posted here.

The other is that I've been privileged to be around several C91 tablets, have had an Idolian Touch Tab 10, have friends who have a couple of XOOMs, two ASUS tablets, and an ARCHOS as well as two IPADs. For the most part I have been very favorably impressed with my dealer, and the support I've had from Zenithink as well as support I've had from Slatedroid. I just love my Zenithink C91.

We'll see what happens when I have hands on experience with the C94-Till then-

Thanks for reading...

I do not understand about about the screens (MVA and IPS), can you explain me. How can I do to know if my C94 has any MVA or IPS? Thanks

Hi there,

The Ampe has an IPS screen. The Zenithink, though very good looking does not have quite the resolution, but is nicely saturated and easy on the eyes. Unfortunately, my experience with the C94 has not been good.

Hope you have better experiences.
I use an older Motorola Xoom which serves me very well.

I had had an Ampe A10 Freescale, but cannot, in good conscience recommend the Ampe to anyone.

I had promised a comparison review of my Zenithink C91, the Zenithink C94 and the Ampe A10. I had the chance to have hands on with the C94 the other day, and had a chance to put the C94 through it's paces.

Now, I have to tell you, up front, that I have a Zenithink C91 that I really enjoy. It is a very well constructed, and capable tablet. I will come back to this in a few minutes. Just let me say that my experiences with the C91 have mostly been extremely good and have made me very pre-disposed to like Zenithink's products.

Saying the above though, my first impression of the Zenithink C94 was not very good.

1. There were no instructions in the box.
2. There were no micro to regular usb cables that came with it.
3. My friend, who had bought the tablet, had turned it on, there was a ui error notice, and due to the fact that the default screen shut off was only 1 minute, effectively, at his skill level left him with a bricked tablet.

Well, the first thing I did was to shut off the tablet and reboot it. This is where I discovered that there was, indeed, a Ui error. At that point, I reset the tablet. This did not correct the error. Then I set the screen to never shut itself off, and while in the settings, did a hard reset that wiped the tablet. This took care of the problem. We now had a fully functioning Zenithink C94, or so I thought! What would my friend have done without someone who knew what he was doing? This first experience with the C94 had dampened my enthusiasm for Zenithink. Putting this in perspective then, let's move on.

Now, having what appeared to be a fully functioning C94, let's look at appearances. No one has, till now, answered the question as to whether the C94 has a glass screen or not-Yes, it has a glass screen. The overall heft and feel of the C94 is quite good, and screams quality. Everything fits extremely well and has the little touches that give an overall comfortableness and solidity to the tablet. In fact, I found the C94 to be very attractive. The white plastic back was no problem, as my C91 also has one.

The ports on the Zenithink are good as it has two USB ports, HDMI, headphone, and mic ports as well. It also has a reset. These all fit well. I wish they had kept a full sized USB port but Zenithink chose to drop it.

I really don't like the positioning of the ports on the C94 along the top of the machine. I wish they had placed these along the right hand side.

Another problem is the positioning of the On/Off and Volume switches along the upper back right hand side. They are smaller than I'd have liked , but were beautiful there. If you try to buy a case that will fit it, you're out of luck unless you get a very expensive case that allows some serious customization. Seriously, the appearance of the tablet is quite pretty. It is only about half the thickness of my C91 as it is, it is about a ½ inch shorter and a ½ inch wider than the C91, though the screen size is the same as the C91. It lacks the icons that are along the right side of the C91, instead only has standard ICS icons along the left bottom of the screen. That's right, in spite of what you might have seen and heard, the C94 is still running under ICS 4.0.3. In spite of the advertising, Zenithink shipped the tablet before they had Jelly Bean fixed for it. It also has an 8 gig nand ram drive. When you boot the machine up it operates smoothly. There was very little time between pressing the on button and boot up. I was impressed. I found very little in the way of apps pre-installed, and had to load everything my friend wanted in the way of software. All of this came from the Play Store, and had no problem downloading, installing or operating. However, on that particular day the Store would not download Antutu or Quadrant to do speed tests. I think it was because the Zt/I. MX6Q was not registered with them yet.

By the time I got through doing my work that night, his tablet seemed to work very well indeed. It's very fast and capable. The inability to find a case for it, and the placement of the ports would put me off. I'll have more to say later, but my C91 compared very favourably against the C94, though it didn't appear to be anywhere near as fast. The battery life seems to be very good. Since this time I have found out that the firmware is very poor. There is no Bluetooth recognition, nor do either of the USB ports work.

I have sadly recommended that my friend return the tablet for the following reasons.
1. The tablet came without cables or instructions.
2. The UI (User Interface) was corrupted before he ever touched it.
3. The advertising clearly stated that the tablet had Android 4.1. It did not! It came with Android 4.0.3.
4. It was advertised as having two working USB ports. Neither of these work.
5. I discovered that there is no provision for Bluetooth on this tablet even though this was one of the selling points in the advertisements.

Even downloading the latest firmware did not help these problems. These issues carried on to the new firmware which was flawed in the same way, in fact, the firmware upgrade clearly states that it is a beta version of Android 4.0.3..

The hardware appears to be good, but the firmware is shoddy, and only partially functional.

Since I had owned an Upgraded Zenithink C91 I really thought that Zenithink would market a good tablet here. I am severely disappointed because of the firmware they marketed it with. Because of this they have been selling nothing but an expensive toy and I can't recommend it.
--------
On the other hand, A couple of days later, I got my Ampe A10 Quad Core.

I opened the box, and saw the tablet. After removing this, I went through the rest of the contents. There were an inexpensive set of earbuds, a male USB to male micro USB cable, and a female USB to micro male USB cable, and two pieces of paperwork. One of these was an operation manual, and the warranty info. Both of these were in Chinese, and didn't help at all.

The tablet itself is very nice, and extremely beautiful. It booted right up, and I have just loved using it ever since. Yes, there are battery problems, but my dealer is writing a new rom right now that addresses this. In the meantime, Juice Protector has extended the length of the charge to more than four hours. The tablet is extremely well constructed and has a 16 gig internal nand drive. Everything on it works to perfection, and the Play Store is working wonderfully as well. There were programs that either were not completely compatible or were not listed on the Party Store at first, but like Rom Toolbox, which was not there one day, but was the next, compatible versions appear overnight. After running the tablet with more than 180 different apps now, I am really impressed. This is a lightning fast tablet that looks beautiful, and operates wonderfully. The ports are all positioned nicely, fit nicely, show real quality engineering. The screen is a 1280x800 wonder, this is not a higher definition, but larger format screen that really looks good, and makes the tablet about an inch wider than my Zenithink C91. The one drawback is that the screen is made of plastic rather than glass. A good screen protector goes a long way though. Also, the cameras on the tablet could be higher resolution(They're both 2gig cameras), but they have made it easier to get photos when I want them.

The tablet is incredibly fast, runs just about everything you throw at it, and is able to run circles around my Zenithink C91.

For my money, this is the tablet that should have been. It's the best. By the way, Freescale, the manufacturer of the chip set, has promised a soon delivery of a working version of Android 4.1.

The Ampe A10 Quad Core is inexpensive, but a quality tablet that I can heartily recommend-The Ampe A10 Quad Core.

Hi The Kingsman,
Thank you for posting your informative review, it's a real eye opener.... First let me say that I am biased towards Zenithink, since they are the only Android devices that I've ever used, and Zenithink does send me a free tablet now and then so I can help all the Zenithink tablet users in all the Forums I am apart of (they never sent me a ZT-282 though, but I tried to help out as much as I could in that forum).... I just have a few comments about the 5 reasons you wouldn't advise someone getting the tablet... Actually, other than the ZT-283's on ICS, I probably wouldn't recommend any of their other products (that I have) either... :(

1. Usually when Zenithink sends me a tablet, I don't get any cables either, I think some vendors add them before shipping (was it stated on the box that cables were included?).... There is the Help PDF on the media partition or in the ROM download in the media folder (for those who are looking for it)....
2. That really sucks, I'm glad you were able to get it to work for your friend. Do you know which ROM was on it when that happened? Is it possible the data partition got corrupted during transit? Was the battery very low when your friend first turned it on, or did he do the recommended charge for a few hours before turning the tablet on?
3. Yes, many people are upset about that, but the JB ROMs for the ZT-283's (from Zenithink) aren't that stable yet (Christian Troy's ROMs are pretty stable though, especially if you change the default Launcher (Trebuchet) to some other JB compatible Launcher). I think it's better they iron out all the wrinkles on ICS before they even attempt to release a JB ROM for the ZT-285's, or there may not be any stable ROM for the C94 for a long time....
4. I believe the host port is for using the ethernet adapter (I could be wrong though).... And if the other port is like the ZT-283's, you need an OTG adapter for it to work for using USB things, a regular adapter wil not work, and then a regular usb cable for mass storage/connecting to your computer... (If I am wrong, and someone knows the correct answer, please post it.)
5. Does your friend have H8 or H8_1a tablet? All of those don't have internal BT, and only recent (not all) H8_2a tablets have them....

Some things I don't like about the C94's (I don't have one, just from what I've read) are that the current ROMs aren't pre-rooted, and also the files have changed from previous Zenithink tablet ROMs, they are the img files now, not the *.tar.bz files that are easy to edit and share with other people....

I think the concensus may be that Zenithink may not be the best quality but for the price it is good value.

USB worked fine for my xxxH8xxx and once rooted got Huawei 3G external modem to connect fine.

I agree GPS and Bluetooth would have been nice :-) JuiceDefender on aggressive helps the battery life noticeably.

How do I know what firmware I am running cos I plan to update to latest ICS and eventually JB?

Oh I agree with case size comment above. Same issue with getting a screen protector. I have a couple on order for acer tablet which has similar dimensions.

(You can easily transfer antutu apk as it looks 'unsupported by device' on GooglePlay)

There should be a txt file in /mnt/sdcard, a version.txt that tells you when you open it, and/or a txt file with the name of the ROM as the filename (like ZT285_H8_1a_1GB_Android4.0_1205_V1.12.txt would mean you have the 1205 ROM).....

Oh, I forgot the kicker-the Zenithink was not rooted either-The Ampe came rooted from my dealer.
I use an older Motorola Xoom which serves me very well.

I had had an Ampe A10 Freescale, but cannot, in good conscience recommend the Ampe to anyone.
