Hello XDA! Greetings from Berlin.

My name is Johann I'm a Berlin based Electronics Engineer.

You may be wondering why I'm posting here... Right? Well... I'm building my big dream... The fastest ever Android QuadCore tablet based on an Exynos SOC. Yes, the 4412.

Is there anybody here who wants to give me some suggestions?

From now on, my team and I have successfully integrated the SOC, a GPS + BT module, and, an HD Screen.

What would you like to see on a tablet?

Isn't that essentially the Note 10.1?

Well first let me say this is the coolest thing i've seen on here, i know nothing about phone/tablet hardware but i know a LOT about computer hardware, since this is a tablet would a laptop GPU work in it? Also if possible you should try and take a 4G antenna from another tablet and put it in here, Also could you give us detailed specs? Like the PPI and such of the screen?

Mmm... Yes... but the size of the screen will be 8" or 9.7", and, we're building it to never exceed the 159USD as our target price on Bill Of Materials Any suggestion will be appreciated. Thanks for writing!

Hi PantechBurstOwner

That's a good idea. We've been researching about the 4G module, and, actually testing it.

The screen we're testing now is an HD 1024x768px, this one is a normal IPS screen (132PPI from LG), but there's a better one comming. I'll update as soon as it arrives here.

For the 4G modem, the main challange is to find a module thin enough to fit on the casing. On the picture attached you can see the left prototype has 3G module in (A 4G one will fit too), and, the right one is much thinner, and, a 4G module doesn't fit

I think the dimensions of the nexus 7 is prefect, yours looks a bit more like kindle fire HD, personally not a fan of it but I'd still use it :P. Also what are your plans for the speakers and GPU?

Thanks for the comments. For the GPU it'll be the ARM's Mali400 MP (4 Cores Version), the same being used by the Galaxy S3. The CPU will be clocked at 1.6GHZ, so it'll be smooth.

Now we're thinking about the Firmware, as our prototype is now running on Stock Android, but my idea is to do something more impressive.

Which firmware would you love to see running on it? Cyanogen?

Cyanogenmod would be great, if it's smaller though (think 7 inches) think Paranoid Android.

What would really differentiate it, would be if you already had a dual boot preinstalled on it with a little taste of everything. i.e. MIUI, CM10, and one more ultra customizable ROM (I suppose CM10) with themes that could be applied straight through the software. I understand this would probably be a pain to do, but it would make your tablet the MOST versatile tablet out there.

Also, consider like Asus, you may want to consider shoving a port on the bottom for a keyboard dock. Big fan of keyboards...

(Yes I understand I'm practically spamming you with ideas and not many of them are possible, nonetheless, lots of ideas are better than none... no?)

Would you consider a proposal to the cyanogenmod team? It'll be nice to see a highly customizable stock firmware on a tablet..

Big +1
Ain't using separate 4G module too expensive? I don't think there should be any problem in fitting it onboard if you integrate it into one PCB design.
I'd like to see all unused cpu I/Os breaked out into set of pads onboard and documented, like UART, second USB port, I2C bus, FIMC interfaces and so on.

Also, don't get me wrong but if this project doesn't get realised (I really wish it does) - please publish non-NDA documentation. :]
